From afbaade3dc99838a0c39699bea175674f27322a1 Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Fri, 8 Jun 2012 10:56:48 +0200 Subject: delete seven tty headers Commit 51c9d654c2def97827395a7fbfd0c6f865c26544 ("Staging: delete tty drivers") left seven headers unused: nothing in the tree includes them anymore. Two of those headers were still exported, but since nothing in the kernel actually uses the things those two headers provide, that seems pointless. Delete these seven tty headers too.

These features boil down to what each arch does in the mcount trampoline (the ftrace_caller). Currently there's two features that are not the same throughout the archs. 1) Support to stop function tracing before the callback 2) passing of the ftrace ops Both of these require placing an indirect function to support the features if the mcount trampoline does not. On a side note, for all architectures, when more than one callback is registered to the function tracer, an intermediate 'list' function is called by the mcount trampoline to iterate through the callbacks that are registered. Instead of making a separate function for each of these features, and requiring several indirect calls, just use the single 'list' function as the intermediate, to handle all cases. If an arch does not support the 'stop function tracing' or the passing of ftrace ops, just force it to use the list function that will handle the features required.

If a ftrace_ops wants regs saved on the return, then have only the functions with ops registered to save regs. Functions registered by other ops would not be affected, unless the functions overlap. If one ftrace_ops registered functions A, B and C and another ops registered fucntions to save regs on A, and D, then only functions A and D would be saving regs. Function B and C would work as normal. Although A is registered by both ops: normal and saves regs; this is fine as saving the regs is needed to satisfy one of the ops that calls it but the regs are ignored by the other ops function. x86_64 implements the full regs saving, and i386 just passes a NULL for regs to satisfy the ftrace_ops passing. Where an arch must supply both regs and ftrace_ops parameters, even if regs is just NULL. It is OK for an arch to pass NULL regs. All function trace users that require regs passing must add the flag FTRACE_OPS_FL_SAVE_REGS when registering the ftrace_ops. If the arch does not support saving regs then the ftrace_ops will fail to register. The flag FTRACE_OPS_FL_SAVE_REGS_IF_SUPPORTED may be set that will prevent the ftrace_ops from failing to register. In this case, the handler may either check if regs is not NULL or check if ARCH_SUPPORTS_FTRACE_SAVE_REGS. If the arch supports passing regs it will set this macro and pass regs for ops that request them. All other archs will just pass NULL.

With using ftrace optimization, kprobes on the mcount calling address, use ftrace's mcount call instead of breakpoint. Furthermore, this optimization works with preemptive kernel not like as current jump-based optimization. Of cource, this feature works only if the probe is on mcount call. Only if kprobe.break_handler is set, that probe is not optimized with ftrace (nor put on ftrace). The reason why this limitation comes is that this break_handler may be used only from jprobes which changes ip address (for fetching the function arguments), but function tracer ignores modified ip address. Changes in v2: - Fix ftrace_ops registering right after setting its filter. - Unregister ftrace_ops if there is no kprobe using. - Remove notrace dependency from __kprobes macro.

In the limit case of discard_granularity == max_discard_sectors, no request could be aligned correctly, so in fact you might end up with no discarded logical blocks at all. Another example that helps showing the condition in the patch is with discard_granularity == 64, max_discard_sectors == 128. A request that is submitted for 256 sectors 2..257 will be split in two: 2..129, 130..257. However, only 2 aligned blocks out of 3 are included in the request; 128..191 may be left intact and not discarded. With this patch, the first request will be truncated to ensure good alignment of what's left, and the split will be 2..127, 128..255, 256..257. The patch will also take into account the discard_alignment. At most one extra request will be introduced, because the first request will be reduced by at most granularity-1 sectors, and granularity must be less than max_discard_sectors. Subsequent requests will run on round_down(max_discard_sectors, granularity) sectors, as in the current code.

One example is a node that's used to collect a number of non-memory-mapped devices. In that scenario, there may be multiple child nodes with the same name (type) thus necessitating the use of unit addresses in node names, and reg properties: / { regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; regulator@0 { compatible = "regulator-fixed"; reg = <0>; ... }; regulator@1 { compatible = "regulator-fixed"; reg = <1>; ... }; ... }; }; However, #size-cells=0 prevents translation of reg property values into the parent node's address space. In turn, this triggers the kernel to emit error messages during boot, such as: prom_parse: Bad cell count for /regulators/regulator@0 To prevent printing these error messages for legitimate DT content, a number of changes are made: 1) of_get_address()/of_get_pci_address() are modified only to validate the value of #address-cells, and not #size-cells. 2) of_can_translate_address() is added to indicate whether address translation is possible. 3) of_device_make_bus_id() is modified to name devices based on the translated address only where possible, and otherwise fall back to using the (first cell of the) raw untranslated address. 4) of_device_alloc() is modified to create memory resources for a device only if the address can be translated into the CPU's address space.

If the work item is queued, the rest point to the cpu_workqueue with WORK_STRUCT_CWQ set; otherwise, WORK_STRUCT_CWQ is clear and the bits contain the last CPU number - either a real CPU number or one of WORK_CPU_*. Scheduled addition of mod_delayed_work[_on]() requires an additional flag, which is used only while a work item is off queue. There are more than enough bits to represent off-queue CPU number on both 32 and 64bits. This patch introduces WORK_OFFQ_FLAG_* which occupy the lower part of the @work->data high bits while off queue. This patch doesn't define any actual OFFQ flag yet. Off-queue CPU number is now shifted by WORK_OFFQ_CPU_SHIFT, which adds the number of bits used by OFFQ flags to WORK_STRUCT_FLAG_SHIFT, to make room for OFFQ flags. To avoid shift width warning with large WORK_OFFQ_FLAG_BITS, ulong cast is added to WORK_STRUCT_NO_CPU and, just in case, BUILD_BUG_ON() to check that there are enough bits to accomodate off-queue CPU number is added.

One is when someone else is queueing or deqeueing the work item. With the previous patches, it is guaranteed that PENDING and queued state will soon agree making it safe to busy-retry in this case. The other is if multiple __cancel_work_timer() invocations are racing one another. __cancel_work_timer() grabs PENDING and then waits for running instances of the target work item on all CPUs while holding PENDING and !queued. try_to_grab_pending() invoked from another task will keep returning -EAGAIN while the current owner is waiting. Not distinguishing the two cases is okay because __cancel_work_timer() is the only user of try_to_grab_pending() and it invokes wait_on_work() whenever grabbing fails. For the first case, busy looping should be fine but wait_on_work() doesn't cause any critical problem. For the latter case, the new contender usually waits for the same condition as the current owner, so no unnecessarily extended busy-looping happens. Combined, these make __cancel_work_timer() technically correct even without irq protection while grabbing PENDING or distinguishing the two different cases. While the current code is technically correct, not distinguishing the two cases makes it difficult to use try_to_grab_pending() for other purposes than canceling because it's impossible to tell whether it's safe to busy-retry grabbing. This patch adds a mechanism to mark a work item being canceled. try_to_grab_pending() now disables irq on success and returns -EAGAIN to indicate that grabbing failed but PENDING and queued states are gonna agree soon and it's safe to busy-loop. It returns -ENOENT if the work item is being canceled and it may stay PENDING && !queued for arbitrary amount of time. __cancel_work_timer() is modified to mark the work canceling with WORK_OFFQ_CANCELING after grabbing PENDING, thus making try_to_grab_pending() fail with -ENOENT instead of -EAGAIN. Also, it invokes wait_on_work() iff grabbing failed with -ENOENT. This isn't necessary for correctness but makes it consistent with other future users of try_to_grab_pending(). v2: try_to_grab_pending() was testing preempt_count() to ensure that the caller has disabled preemption. This triggers spuriously if !CONFIG_PREEMPT_COUNT. Use preemptible() instead. Reported by Fengguang Wu. v3: Updated so that try_to_grab_pending() disables irq on success rather than requiring preemption disabled by the caller. This makes busy-looping easier and will allow try_to_grap_pending() to be used from bh/irq contexts.

This patch implements mod_delayed_work[_on]() which behaves similarly to mod_timer() - if the delayed_work is idle, it's queued with the given delay; otherwise, its timeout is modified to the new value. Zero @delay guarantees immediate execution. v2: Updated to reflect try_to_grab_pending() changes. Now safe to be called from bh context.

Otherwise, when the root file system is mounted read-only, the journal is replayed, and the error indicator is transferred to the superblock --- but the s_errno field in the jbd2 superblock is left set (since although we cleared it in memory, we never flushed it out to disk).

(If we have multiple rings and no semaphores, userspace assumes that the cost of switching rings between batches is exorbitant and will endeavour to keep the next batch on the active ring - as a coarse approximation to tracking both destination and source surfaces.) Currently userspace has to guess whether semaphores exist based on the chipset generation and the module parameter, i915.semaphores. This is a crude and inaccurate guess as the defaults internally depend upon other chipset features being enabled or disabled, nor does it extend well into the future. By exporting a HAS_SEMAPHORES parameter, we can easily query the driver and obtain an accurate answer.

The size of the dump is specified by sample_stack_user value. Being able to dump parts of the user stack, starting from the stack pointer, will be useful to make a post mortem dwarf CFI based stack unwinding. Added HAVE_PERF_USER_STACK_DUMP config option to determine if the architecture provides user stack dump on perf event samples. This needs access to the user stack pointer which is not unified across architectures. Enabling this for x86 architecture.

To avoid a race with open, this has to be performed before tty_register_device. But currently tty_driver->ports is allocated even in tty_register_device because we do not know whether this is the PTY driver. The PTY driver is special here due to an excessive count of lines it declares to handle. We cannot handle tty_ports there this way. To circumvent this, we start passing tty_driver flags to alloc_tty_driver already and we create tty_alloc_driver for this purpose. There we can allocate tty_driver->ports and do all the magic between tty_alloc_driver and tty_register_device. Later we will introduce tty_port_link_device function for that purpose. All drivers should eventually switch to this new tty driver allocation interface.

On registration the threads for already online cpus are created and started. On deregistration (modules) the threads are stoppped. During hotplug operations the threads are created, started, parked and unparked. The datastructure for registration provides a pointer to percpu storage space and optional setup, cleanup, park, unpark functions. These functions are called when the thread state changes. Each implementation has to provide a function which is queried and returns whether the thread should run and the thread function itself. The core code handles all state transitions and avoids duplicated code in the call sites. [ paulmck: Preemption leak fix ] Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Reviewed-by: Srivatsa S.

However, this has revealed some problems running hackbench on SMP platforms due to the way in which the MUTEX_SPIN_ON_OWNER code operates. The symptoms are that a bunch of hackbench tasks are left waiting on an unlocked mutex and therefore never get woken up to claim it. This boils down to the following sequence of events: Task A Task B Task C Lock value 0 1 1 lock() 0 2 lock() 0 3 spin(A) 0 4 unlock() 1 5 lock() 0 6 cmpxchg(1,0) 0 7 contended() -1 8 lock() 0 9 spin(C) 0 10 unlock() 1 11 cmpxchg(1,0) 0 12 unlock() 1 At this point, the lock is unlocked, but Task B is in an uninterruptible sleep with nobody to wake it up. This patch fixes the problem by ensuring we put the lock into the contended state if we fail to acquire it on the fastpath, ensuring that any blocked waiters are woken up when the mutex is released.

The driver is mostly the same as found in the original 2.6.28 based kernel that comes with the device. The following modifications have been made compared to the original driver version: - Adopt to the changes that has happen in the kernel during the past five years, such as the change in the include paths - The OMAP DM-timers require much more care nowadays. The timers need to be enabled and disabled or otherwise many actions fail. Timers must not be freed without first stopping them or otherwise the timer cannot be requested again. The code has been tested with sending IR codes with N900 device running Debian userland. The device receiving the codes was Anysee DVB-C USB receiver.

The target CPU is implicitly recorded as the CPU the timer is queued on and delayed_work_timer_fn() queues delayed_work->work to the CPU it is running on. Unfortunately, this leaves flush_delayed_work[_sync]() no way to find out which CPU the delayed_work was queued for when they try to re-queue after killing the timer. Currently, it chooses the local CPU flush is running on. This can unexpectedly move a delayed_work queued on a specific CPU to another CPU and lead to subtle errors. There isn't much point in trying to save several bytes in struct delayed_work, which is already close to a hundred bytes on 64bit with all debug options turned off. This patch adds delayed_work->cpu to remember the CPU it's queued for. Note that if the timer is migrated during CPU down, the work item could be queued to the downed global_cwq after this change. As a detached global_cwq behaves like an unbound one, this doesn't change much for the delayed_work.

With these changes lookups in the port hash table becomes safe to use in multiple network namespaces. Signed-off-by: "Eric W. Biederman" Acked-by: Vlad Yasevich Signed-off-by: David S.

Also unexpected behavior could occur if large negative offsets are injected via adjtimex. So this patch improves the sanity check timekeeping inputs by improving the timespec_valid() check, and then makes better use of timespec_valid() to make sure we don't set the time to an invalid negative value or one that overflows ktime_t. Note: This does not protect from setting the time close to overflowing ktime_t and then letting natural accumulation cause the overflow.

However there are cases where multiple instances of a device type can exist, and their IDs aren't (and can't be) known in advance and do not matter. In that case we need automatic device IDs to avoid device name collisions. I am using magic ID value -2 (PLATFORM_DEVID_AUTO) for this, similar to -1 for ID-less devices. The automatically allocated device IDs are global (to avoid an additional per-driver cost.) We keep note that the ID was automatically allocated so that it can be freed later. Note that we also restore the ID to PLATFORM_DEVID_AUTO on error and device deletion, to avoid avoid unexpected behavior on retry. I don't really expect retries on platform device addition, but better safe than sorry.

Also introduce one private field in 'struct firmware', so release_firmware will see the instance of firmware_buf associated with the current firmware instance, then just 'free' the instance of firmware_buf. The firmware_buf instance represents one pages buffer for one firmware image, so lots of firmware loading requests can share the same firmware_buf instance if they request the same firmware image file. This patch will make implementation of the following cache_firmware/ uncache_firmware very easy and simple. In fact, the patch improves request_formware/release_firmware: - only request userspace to write firmware image once if several devices share one same firmware image and its drivers call request_firmware concurrently.

In theory udl would need a flag also, but I intend to push the patches very close to each other and other drivers should do the right thing from the start. I've added a test to my intel-gpu-tools prime branch, however testing this is a bit messy since the only way to get udl to vmap is to rendering something.

To make it happen compiler inserts padding between struct fields if they are not aligned correctly. Reorder fields to remove paddings and make structures denser. Making data smaller saves some memory that is very important for trace events.

It is thus read again on one of the sockets of the fanout group. This result in a loop for software which generate packets when receiving one. This retransmission is not the intended behavior: a fanout group must behave like a single socket. The packet should not be transmitted on a socket if it originates from a socket belonging to the same fanout group.

This makes it impossible to wait for its completion from IRQ handlers and difficult to shoot down a timer from IRQ handlers. This issue caused some issues for delayed_work interface. Because there's no way to reliably shoot down delayed_work->timer from IRQ handlers, __cancel_delayed_work() can't share the logic to steal the target delayed_work with cancel_delayed_work_sync(), and can only steal delayed_works which are on queued on timer. Similarly, the pending mod_delayed_work() can't be used from IRQ handlers. This patch adds a new timer flag TIMER_IRQSAFE, which makes the timer to be executed without enabling IRQ after dequeueing such that its dequeueing and execution are atomic against IRQ handlers. This makes it safe to wait for the timer's completion from IRQ handlers, for example, using del_timer_sync(). It can never be executing on the local CPU and if executing on other CPUs it won't be interrupted until done. This will enable simplifying delayed_work cancel/mod interface.

Also, unlike other flush and cancel functions, a canceled delayed_work would still point to the last associated cpu_workqueue. If the workqueue is destroyed afterwards and the work item is re-used on a different workqueue, the queueing code can oops trying to dereference already freed cpu_workqueue. This patch reimplements cancel_delayed_work() using try_to_grab_pending() and set_work_cpu_and_clear_pending(). This allows the function to be called from IRQ handlers and makes its behavior consistent with other flush / cancel functions.

The kernel passes all-zero SCM_CREDENTIALS ancillary data to the receiver if the sender did not provide such data, instead of not including any such data at all or including the correct data from the peer (as it is the case with AF_UNIX). This bug was introduced in commit 16e572626961 (af_unix: dont send SCM_CREDENTIALS by default) This patch forces passing credentials for netlink, as before the regression. Another fix would be to not add SCM_CREDENTIALS in netlink messages if not provided by the sender, but it might break some programs.

Very broadly speaking this patch expands the concept. This patch introduces compact_checklock_irqsave() to check if a lock is contended or the process needs to be scheduled. If either condition is true then async compaction is aborted and the caller is informed. The page allocator will fail a THP allocation if compaction failed due to contention. This patch also introduces compact_trylock_irqsave() which will acquire the lock only if it is not contended and the process does not need to schedule.

In the same fashion as similar translation functions in linux/mii.h, move these functions from the PHYLIB core to the linux/mdio.h header file so the code will not have to be duplicated in each driver needing MMD-to-ethtool (and vice-versa) translations. The function and some variable names have been renamed to be more descriptive. Not tested on the only hardware that currently calls the related functions, stmmac, because I don't have access to any.

This lock currently protects two modifications: * sklist * prot inuse counters The sklist modifications can be just reprotected with mutex since they already occur in a sleeping context. The inuse counters modifications are trickier -- the __this_cpu_-s are used inside, thus requiring the caller to handle the potential issues with contexts himself. Since packet sockets' counters are modified in two places only (packet_create and packet_release) we only need to protect the context from being preempted. BH disabling is not required in this case.

In v1 Capability structures (PCIe spec r1.0 and r1.1), some fields are optional, so the structure size depends on the device type. This patch adds functions to access this capability so drivers don't have to be aware of the differences between v1 and v2. Note that these new functions apply only to the "PCI Express Capability," not to any of the other "PCI Express Extended Capabilities" (AER, VC, ACS, MFVC, etc.) Function pcie_capability_read_word/dword() reads the PCIe Capabilities register and returns the value in the reference parameter "val". If the PCIe Capabilities register is not implemented on the PCIe device, "val" is set to 0. Function pcie_capability_write_word/dword() writes the value to the specified PCIe Capability register.

It can not validate links have resumed properly until libata has had a chance to perform its revalidation, and any sane placing of an ata_port in the sas-transport model would delay it's resumption until after the host. Export the common portion of port suspend/resume (bypass pm_runtime), and allow sas to perform these operations asynchronously (similar to the libsas async-ata probe implmentation).

The default carrier state of a net device is on, and this will never be changed on drivers that do not support carrier detection, thus the operstate remains IF_OPER_UNKNOWN. For devices that do support carrier detection, the driver must set the carrier state to off initially, then poll the hardware state when the device is opened. However, we must not activate linkwatch for a unregistered device, and commit b473001 ('net: Do not fire linkwatch events until the device is registered.') ensured that we don't. But this means that the operstate for many devices that support carrier detection remains IF_OPER_UNKNOWN when it should be IF_OPER_DOWN. The same issue exists with the dormant state. The proper initialisation sequence, avoiding a race with opening of the device, is: rtnl_lock(); rc = register_netdevice(dev); if (rc) goto out_unlock; netif_carrier_off(dev); /* or netif_dormant_on(dev) */ rtnl_unlock(); but it seems silly that this should have to be repeated in so many drivers. Further, the operstate seen immediately after opening the device may still be IF_OPER_UNKNOWN due to the asynchronous nature of linkwatch. Commit 22604c8 ('net: Fix for initial link state in 2.6.28') attempted to fix this by setting the operstate synchronously, but it was reverted as it could lead to deadlock.

The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

Refragmentation uses the dst_mtu() of the local route without caring about the original fragment sizes, thereby breaking PMTUD.

This includes register access, as well as trigger handling. But each device sub-family has different features and different register layouts (some even have no registers at all) and thus it is impractical to try to support all of the devices by the same driver. This patch adds a common base library for Sigma Delta converter devices. It will be used by individual drivers. This code is mostly based on the three existing Sigma Delta drivers the AD7192, AD7780 and AD7793, but has been improved for more robustness and flexibility.

It is also checked in uprobe_munmap() but ironically its only goal to decrement this counter. However, it is very broken. Just some examples: - uprobe_mmap() can race with uprobe_unregister() and wrongly increment the counter if it hits the non-uprobe "int3". Note that install_breakpoint() checks ->consumers first and returns -EEXIST if it is NULL. "atomic_sub() if error" in uprobe_mmap() looks obviously wrong too. - uprobe_munmap() can race with uprobe_register() and wrongly decrement the counter by the same reason. - Suppose an appication tries to increase the mmapped area via sys_mremap(). vma_adjust() does uprobe_munmap(whole_vma) first, this can nullify the counter temporarily and race with another thread which can hit the bp, the application will be killed by SIGTRAP. - Suppose an application mmaps 2 consecutive areas in the same file and one (or both) of these areas has uprobes. In the likely case mmap_region()->vma_merge() suceeds. Like above, this leads to uprobe_munmap/uprobe_mmap from vma_merge()->vma_adjust() but then mmap_region() does another uprobe_mmap(resulting_vma) and doubles the counter. This patch only removes this counter and fixes the compile errors, then we will try to cleanup the changed code and add something else instead.

It is set by install_breakpoint() and it is copied by dup_mmap(), uprobe_pre_sstep_notifier() checks it to avoid the slow path if the task was never probed. Perhaps it makes sense to check it in valid_vma(is_register => false) as well. This needs the new dup_mmap()->uprobe_dup_mmap() hook. We can't use uprobe_reset_state() or put MMF_HAS_UPROBES into MMF_INIT_MASK, we need oldmm->mmap_sem to avoid the race with uprobe_register() or mmap() from another thread.

Fragmentes are collected in PREROUTING/OUTPUT, are defragmented, the defragmented packet is then passed to conntrack, the resulting conntrack information is attached to each original fragment and the fragments then continue their way through the stack. Helper invocation occurs in the POSTROUTING hook, at which point only the original fragments are available. The result of this is that fragmented packets are never passed to helpers. This patch improves the situation in the following way: - If a reassembled packet belongs to a connection that has a helper assigned, the reassembled packet is passed through the stack instead of the original fragments. - During defragmentation, the largest received fragment size is stored. On output, the packet is refragmented if required. If the largest received fragment size exceeds the outgoing MTU, a "packet too big" message is generated, thus behaving as if the original fragments were passed through the stack from an outside point of view. - The ipv6_helper() hook function can't receive fragments anymore for connections using a helper, so it is switched to use ipv6_skip_exthdr() instead of the netfilter specific nf_ct_ipv6_skip_exthdr() and the reassembled packets are passed to connection tracking helpers. The result of this is that we can properly track fragmented packets, but still generate ICMPv6 Packet too big messages if we would have before. This patch is also required as a precondition for IPv6 NAT, where NAT helpers might enlarge packets up to a point that they require fragmentation. In that case we can't generate Packet too big messages since the proper MTU can't be calculated in all cases (f.i. when changing textual representation of a variable amount of addresses), so the packet is transparently fragmented iff the original packet or fragments would have fit the outgoing MTU.

If set it to 1, the mask value will be inverted before written to mask_base Signed-off-by: Xiaofan Tian Signed-off-by: Mark Brown --- include/linux/regmap.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/linux/regmap.h b/include/linux/regmap.h index 9c4c9c673f38..e3bcc3f4dcb8 100644 --- a/include/linux/regmap.h +++ b/include/linux/regmap.h @@ -300,6 +300,7 @@ struct regmap_irq_chip { unsigned int ack_base; unsigned int wake_base; unsigned int irq_reg_stride; + unsigned int mask_invert; bool runtime_pm; int num_regs; -- cgit v1.2.2 From 85b8614d722389202af298e1bf8a599c431fef19 Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Fri, 24 Aug 2012 20:46:18 +0200 Subject: usb: gadget: get rid of USB_GADGET_{DUAL,SUPER}SPEED This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED Kconfig options. Since now kernel allows many UDC drivers to be compiled, those options may turn to no longer be valid. For instance, if someone decides to build UDC that supports super speed and UDC that supports high speed only, the latter will be "assumed" to support super speed since USB_GADGET_SUPERSPEED will be selected by the former. The test of whether CONFIG_USB_GADGET_*SPEED was defined was just an optimisation which removed otherwise dead code (ie. if UDC is not dual speed, there is no need to handle cases that can happen if speed is high). This commit removes those checks.

However, this is not true if reliable events are enabled. In that case, del_timer may return true for entries that were just inserted in the dying list. Note that packets / ctnetlink may hold references to conntrack entries that were just inserted to such list. This patch fixes the issue by adding an independent timer for event delivery. This increases the size of the ecache extension. Still we can revisit this later and use variable size extensions to allocate this area on demand.

This reduced the time till the last SYN retransmission packet gets sent from 93secs to 31secs. RFC1122 is stating that the retransmission should be done for at least 3 minutes, but this seems to be quite high. "However, the values of R1 and R2 may be different for SYN and data segments. In particular, R2 for a SYN segment MUST be set large enough to provide retransmission of the segment for at least 3 minutes. The application can close the connection (i.e., give up on the open attempt) sooner, of course." This patch increases the value of TCP_SYN_RETRIES to the value of 6, providing a retransmission window of 63secs. The comments for SYN and SYNACK retries have also been updated to describe the current settings. The same goes for the documentation file "Documentation/networking/ip-sysctl.txt".

It also documents a number of flags for the sysctl_tcp_fastopen knob, and adds a few Linux extension MIBs. In addition, it includes the following: 1. a new TCP_FASTOPEN socket option an application must call to supply a max backlog allowed in order to enable TFO on its listener. 2. A number of key data structures: "fastopen_rsk" in tcp_sock - for a big socket to access its request_sock for retransmission and ack processing purpose. It is non-NULL iff 3WHS not completed. "fastopenq" in request_sock_queue - points to a per Fast Open listener data structure "fastopen_queue" to keep track of qlen (# of outstanding Fast Open requests) and max_qlen, among other things. "listener" in tcp_request_sock - to point to the original listener for book-keeping purpose, i.e., to maintain qlen against max_qlen as part of defense against IP spoofing attack. 3. various data structure and functions, many in tcp_fastopen.c, to support server side Fast Open cookie operations, including /proc/sys/net/ipv4/tcp_fastopen_key to allow manual rekeying.

This includes - 1. allocating, properly initializing, and managing the per listener fastopen_queue structure when TFO is enabled 2. changes to the inet_csk_accept code to support TFO. E.g., the request_sock can no longer be freed upon accept(), not until 3WHS finishes 3. allowing a TCP_SYN_RECV socket to properly poll() and sendmsg() if it's a TFO socket 4. properly closing a TFO listener, and a TFO socket before 3WHS finishes 5. supporting TCP_FASTOPEN socket option 6. modifying tcp_check_req() to use to check a TFO socket as well as request_sock 7. supporting TCP's TFO cookie option 8. adding a new SYN-ACK retransmit handler to use the timer directly off the TFO socket rather than the listener socket. Note that TFO server side will not retransmit anything other than SYN-ACK until the 3WHS is completed. The patch also contains an important function "reqsk_fastopen_remove()" to manage the somewhat complex relation between a listener, its request_sock, and the corresponding child socket. See the comment above the function for the detail. Signed-off-by: H.K. Jerry Chu Cc: Yuchung Cheng Cc: Neal Cardwell Cc: Eric Dumazet Cc: Tom Herbert Signed-off-by: David S.

Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid.

Wysocki" Date: Mon, 6 Aug 2012 01:46:39 +0200 Subject: PM / Domains: Move syscore flag from subsys data to struct device The syscore device PM flag is used to mark the devices (belonging to a PM domain) that should never be turned off, except for the system core (syscore) suspend/hibernation and resume stages. That flag is stored in the device's struct pm_subsys_data object whose address is available from struct device. However, in some situations it may be convenient to set that flag before the device is added to a PM domain, so it is better to move it directly to the "power" member of struct device. Then, it can be checked by the routines in drivers/base/power/runtime.c and drivers/base/power/main.c, which is more straightforward. This also reduces the number of dev_gpd_data() invocations in the generic PM domains framework, so the overhead related to the syscore flag is slightly smaller. Signed-off-by: Rafael J.

For several MoviNAND eMMC parts, there are known issues with secure erase and secure trim. For these specific MoviNAND devices, we skip these operations. Specifically, there is a bug in the eMMC firmware that causes unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE enabled.

This RFC assumes that the sequence number counters are always up to date. However, this is not true if an async crypto algorithm is employed. If the sequence number counters are not up to date on sequence number check, we may incorrectly update the upper 32 bit of the sequence number. This leads to a DOS. We workaround this by comparing the upper sequence number, (used for authentication) with the upper sequence number computed after the async processing. We drop the packet if these numbers are different. To do this, we introduce a recheck function that does this check in the ESN case.

At this point, NFS_COOKIEVERF seems to be more of an obfuscation than a helper, so the best thing would be to just get rid of it.

Rather than change the sunsu.c driver, simply move the struct to be within the exclusive domain of that driver, so it won't get inadvertently picked up and used by other serial drivers going forward. The comments referencing the now driver specific struct are updated accordingly. Note that 8250.c has a struct that is similar in usage, with the name serial8250_config; but is 100% independent and untouched here. Cc: "David S.

The main differences from the SC26XX driver: - Removed dependency on MIPS. Driver can be used on any platform. - Added support for SCC2681, SCC2691, SCC2692, SC28L91, SC28L92, SC28L202, SCC68681 and SCC68692 ICs. - Using devm_-related functions. - Improved error handling of serial port, improved FIFO handling. - Ability to load multiple instances of drivers. To avoid the possibility of regression, driver SC26XX left in the system to confirm the stability of the driver on platforms where it is being used.

The current overflow checking is broken, resulting in Oopses on user-triggered nfs4_getfacl calls, and is opaque to the point where several attempts at fixing it have failed. This patch tries to clean up the code in addition to fixing the Oopses by ensuring that the overflow checks are performed in a single place (decode_getacl). If the overflow check failed, we will still be able to report the acl length, but at least we will no longer attempt to cache the acl or copy the truncated contents to user space.

I had a hard time trying to disable it anyway ;-) The problem this time is lots of code assuming that a call to add_uevent_var() will guarantee that env->buflen > 0. This is not true if CONFIG_HOTPLUG is unset. So things like this end up overwriting env->envp_idx because the array index is -1: if (add_uevent_var(env, "MODALIAS=")) return -ENOMEM; len = input_print_modalias(&env->buf[env->buflen - 1], sizeof(env->buf) - env->buflen, dev, 0); Don't know what the best action is, given that there seem to be a *lot* of this around the kernel. This patch "fixes" the problem for me, but I don't know if it can be considered an appropriate fix. [ It is the correct fix for now, for 3.7 forcing CONFIG_HOTPLUG to always be on is the longterm fix, but it's too late for 3.6 and older kernels to resolve this that way - gregkh ] Reported-by: Fengguang Wu Signed-off-by: Bjørn Mork Tested-by: Fengguang Wu Cc: stable Signed-off-by: Greg Kroah-Hartman --- include/linux/kobject.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include') diff --git a/include/linux/kobject.h b/include/linux/kobject.h index fc615a97e2d3..1e57449395b1 100644 --- a/include/linux/kobject.h +++ b/include/linux/kobject.h @@ -224,7 +224,7 @@ static inline int kobject_uevent_env(struct kobject *kobj, static inline __printf(2, 3) int add_uevent_var(struct kobj_uevent_env *env, const char *format, ...) -{ return 0; } +{ return -ENOMEM; } static inline int kobject_action_type(const char *buf, size_t count, enum kobject_action *type) -- cgit v1.2.2 From 657b306a7bdfca4ae1514b533a0e7c3c6d26dbc6 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 6 Sep 2012 20:27:06 +0530 Subject: usb: phy: add a new driver for omap usb2 phy All phy related programming like enabling/disabling the clocks, powering on/off the phy is taken care of by this driver.

It's a bit more code, but that is the only downside. On the bright side we have: - Ability to make persistent_ram module removable (when needed, we can move ftrace_ops struct into a module). Note that persistent_ram is still not removable for other reasons, but with this patch it's just one thing less to worry about; - Pstore part is more isolated from the generic function tracer. We tried it already by registering our own tracer in available_tracers, but that way we're loosing ability to see the traces while we record them to pstore. This solution is somewhere in the middle: we only register "internal ftracer" back-end, but not the "front-end"; - When there is only pstore tracing enabled, the kernel will only write to the pstore buffer, omitting function tracer buffer (which, of course, still can be enabled via 'echo function > current_tracer').

The IMA-appraisal extension adds local integrity validation and enforcement of the measurement against a "good" value stored as an extended attribute 'security.ima'. The initial methods for validating 'security.ima' are hashed based, which provides file data integrity, and digital signature based, which in addition to providing file data integrity, provides authenticity. This patch creates and maintains the 'security.ima' xattr, containing the file data hash measurement. Protection of the xattr is provided by EVM, if enabled and configured. Based on policy, IMA calls evm_verifyxattr() to verify a file's metadata integrity and, assuming success, compares the file's current hash value with the one stored as an extended attribute in 'security.ima'.

This is mainly used in low power retention states where power consumption is extremely low so higher voltage or less clean supplies can be used. Support this by providing ops for the drivers and a consumer API which allows the device to be put into bypass mode if all consumers enable it and the machine enables permission for this. This is not supported as a mode since the existing modes are rarely used due to fuzzy definition and mostly redundant with modern hardware which is able to respond promptly to load changes.

We use this field to distinguish the UDCs from each other. In theory this could be used on the host side to apply certain quirks if the "special" UDC in combination with this gadget is used. This hasn't been done as far as I am aware. In practice it would be better to fix the UDC driver before shipping since a later release might not need this quirk anymore. There are some driver in tree (on the host side) which use the bcdDevice field to figure out special workarounds for a given firmware revision. This seems to make sense. Therefore this patch converts all gadgets (except a few) to use the kernel version instead a random 2 or 3 plus the UDC number. The few that don't report kernel's version are: - webcam This one reports always a version 0x10 so allow it to do so in future. - nokia This one reports always 0x211. The comment says that this gadget works only if the UDC supports altsettings so I added a check for this. - serial This one reports 0x2400 + UDC number. Since the gadget version is 2.4 this could make sense. Therefore bcdDevice is 0x2400 here. I also remove various gadget_is_ macros which are unused. The remaining few macros should be moved to feature / bug bitfield.

So currently such apps are racy and people just live with it. This patch adds a new ioctl which makes it possible for apps to do this in a race free manner. For flexibility apps can choose to: 1) Specify the driver to disconnect 2) Specify to disconnect any driver except for the one named by the app 3) Disconnect any driver Note that if there is no driver attached, the ioctl will just act like the regular claim-interface ioctl, this is by design, as returning an error for this condition would open a new bag of race-conditions.

In the upcoming USB port power off patches, we need to know whether a USB port can ever see a disconnect event. Often USB ports are internal to a system, and users can't disconnect USB devices from that port. Sometimes those ports will remain empty, because the OEM chose not to connect an internal USB device to that port. According to ACPI Spec 9.13, PLD indicates whether USB port is user visible and _UPC indicates whether a USB device can be connected to the USB port (we'll call this "connectible"). Here's a matrix of the possible combinations: Visible Connectible Name Example ------------------------------------------------------------------------- Yes No Unknown (Invalid state.) Yes Yes Hot-plug USB ports on the outside of a laptop. A user could freely connect and disconnect USB devices. No Yes Hard-wired A USB modem hard-wired to a port on the inside of a laptop. No No Not used The port is internal to the system and will remain empty. Represent each of these four states with an enum usb_port_connect_type. The four states are USB_PORT_CONNECT_TYPE_UNKNOWN, USB_PORT_CONNECT_TYPE_HOT_PLUG, USB_PORT_CONNECT_TYPE_HARD_WIRED, and USB_PORT_NOT_USED. When we get the USB port's acpi_handle, store the state in connect_type in struct usb_port.

Upcoming Intel systems will have an ACPI method to control whether a USB port can be completely powered off. The implication of powering off a USB port is that the device and host sees a physical disconnect, and subsequent port connections and remote wakeups will be lost. Add a new function, usb_acpi_power_manageable(), that can be used to find whether the usb port has ACPI power resources that can be used to power on and off the port on these machines. Also add a new function called usb_acpi_set_power_state() that controls the port power via these ACPI methods. When the USB core calls into the xHCI hub driver to power off a port, check whether the port can be completely powered off via this new ACPI mechanism. If so, call into these new ACPI methods. Also use the ACPI methods when the USB core asks to power on a port.

Since this causes some confusion due to the primary use of this resource type for PCI/ISA I/O ports create a new resource type IORESOURCE_REG. Unfortunately the current resource types are specified as bitmasks and there are no free bitmasks even though they really shouldn't be used as such so we define the new type as IORESOURCE_IO | IORESOURCE_MEM. Benjamin Herrenschmidt and Russell King have both verified that none of the users in this series will have a problem with this, and no new code should be affected.

Module code never actually uses that variant of trace functions, because modules don't run code that needs tracing with RCU idled. However, the declaration of those otherwise unused functions causes the module to reference rcu_idle_exit and rcu_idle_enter, which RCU does not export to modules. To avoid this, don't generate trace_*_rcuidle functions for tracepoints declared in module code.

That means that later on Xen will write to it and we'll think that the original mfn is actually what Xen has written to it. Rather than "stealing" struct members from kmap_op, keep using page->index to store the original mfn and add another parameter to m2p_remove_override to get the corresponding kmap_op instead. It is now responsibility of the caller to keep track of which kmap_op corresponds to a particular page in the m2p_override (gntdev, the only user of this interface that passes a valid kmap_op, is already doing that).

This is caused by the (wrong) assumption that RFE in the Status Register is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to the implementation of synchronized byte ordering, e.g.: Dummy-TX - RX - Dummy-TX - RX - ... But since RFE actually stays high after some Dummy-TX, it rather looks like: Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX) The last RX byte is clocked in by the bus controller, but ignored by the kernel when filling the userspace buffer. This patch fixes the issue by asking for RX via Dummy-TX asynchronously. Introducing a separate counter for TX bytes.

This feature enables an HBA and SATA storage device to enter the DevSleep interface state, enabling lower power SATA-based systems. Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as soon as there are no commands outstanding to the device and the port specific Device Sleep idle timer has expired. This enables autonomous entry into the DevSleep interface state without waiting for software in power sensitive systems. This patch enables Aggressive Device Sleep only if both host controller and device support it. Tested on AMD reference board together with Device Sleep supported device sample.

Biederman" Date: Fri, 7 Sep 2012 12:39:21 +0000 Subject: scsi_netlink: Remove dead and buggy code The scsi netlink code confuses the netlink port id with a process id, going so far as to read NETLINK_CREDS(skb)->pid instead of the correct NETLINK_CB(skb).pid. Fortunately it does not matter because nothing registers to respond to scsi netlink requests. The only interesting use of the scsi_netlink interface is fc_host_post_vendor_event which sends a netlink multicast message. Since nothing registers to handle scsi netlink messages kill all of the registration logic, while retaining the same error handling behavior preserving the userspace visible behavior and removing all of the confused code that thought a netlink port id was a process id. This was tested with a kernel allyesconfig build which had no problems. Cc: James Bottomley Cc: James Smart Signed-off-by: "Eric W. Biederman" Signed-off-by: David S.

This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

Since all the builtin subsystems have an id which is lower then CGROUP_BUILTIN_SUBSYS_COUNT we know that any module will have an id larger than CGROUP_BUILTIN_SUBSYS_COUNT. In short the ids are sorted. We are about to change id assignment to happen only at compile time later in this series. That means we can't rely on the above trick since all ids will always be defined at compile time. Furthermore, ordering the builtin subsystems and the module subsystems is not really necessary. So we need a different way to know which subsystem is a builtin or a module one. We can use the subsys[]->module pointer for this. Any place where we need to know if a subsys is module we just check for the pointer. If it is NULL then the subsystem is a builtin one. With this we are able to drop the CGROUP_BUILTIN_SUBSYS_COUNT enum. Though we need to introduce a temporary placeholder so that we don't get a compilation error when only CONFIG_CGROUP is selected and no single controller. An empty enum definition is not valid. Later in this series we are able to remove the placeholder again. And with this change we get a fix for this: kernel/cgroup.c: In function ‘cgroup_load_subsys’: kernel/cgroup.c:4326:38: warning: array subscript is below array bounds [-Warray-bounds] when CONFIG_CGROUP=y and no built in controller was enabled.

For example we define the enums for the subsystems or to declare for struct cgroup_subsys (builtin subsystem) by including cgroup_subsys.h and defining SUBSYS accordingly. Currently, the decision if a subsys is used is defined inside the header by testing if CONFIG_*=y is true. By moving this test outside of cgroup_subsys.h we are able to control it on the include level. This is done by introducing IS_SUBSYS_ENABLED which then is defined according the task, e.g. is CONFIG_*=y or CONFIG_*=m.

A close look is necessary on the RCU part which was introduces by following patch: commit f845172531fb7410c7fb7780b1a6e51ee6df7d52 Author: Herbert Xu Mon May 24 09:12:34 2010 Committer: David S. Miller Mon May 24 09:12:34 2010 cls_cgroup: Store classid in struct sock Tis code was added to init_cgroup_cls() /* We can't use rcu_assign_pointer because this is an int. */ smp_wmb(); net_cls_subsys_id = net_cls_subsys.subsys_id; respectively to exit_cgroup_cls() net_cls_subsys_id = -1; synchronize_rcu(); and in module version of task_cls_classid() rcu_read_lock(); id = rcu_dereference(net_cls_subsys_id); if (id >= 0) classid = container_of(task_subsys_state(p, id), struct cgroup_cls_state, css)->classid; rcu_read_unlock(); Without an explicit explaination why the RCU part is needed. (The rcu_deference was fixed by exchanging it to rcu_derefence_index_check() in a later commit, but that is a minor detail.) So here is my pondering why it was introduced and why it safe to remove it now. Note that this code was copied over to net_prio the reasoning holds for that subsystem too. The idea behind the RCU use for net_cls_subsys_id is to make sure we get a valid pointer back from task_subsys_state(). task_subsys_state() is just blindly accessing the subsys array and returning the pointer. Obviously, passing in -1 as id into task_subsys_state() returns an invalid value (out of lower bound). So this code makes sure that only after module is loaded and the subsystem registered, the id is assigned. Before unregistering the module all old readers must have left the critical section. This is done by assigning -1 to the id and issuing a synchronized_rcu(). Any new readers wont call task_subsys_state() anymore and therefore it is safe to unregister the subsystem. The new code relies on the same trick, but it looks at the subsys pointer return by task_subsys_state() (remember the id is constant and therefore we allways have a valid index into the subsys array). No precautions need to be taken during module loading module. Eventually, all CPUs will get a valid pointer back from task_subsys_state() because rebind_subsystem() which is called after the module init() function will assigned subsys[net_cls_subsys_id] the newly loaded module subsystem pointer. When the subsystem is about to be removed, rebind_subsystem() will called before the module exit() function. In this case, rebind_subsys() will assign subsys[net_cls_subsys_id] a NULL pointer and then it calls synchronize_rcu(). All old readers have left by then the critical section. Any new reader wont access the subsystem anymore. At this point we are safe to unregister the subsystem. No synchronize_rcu() call is needed.

Others show yet different behaviors. These differing interpretations of cgroup hierarchy make using cgroup confusing and it impossible to co-mount controllers into the same hierarchy and obtain sane behavior. Eventually, we want full hierarchy support from all subsystems and probably a unified hierarchy. Users using separate hierarchies expecting completely different behaviors depending on the mounted subsystem is deterimental to making any progress on this front. This patch adds cgroup_subsys.broken_hierarchy and sets it to %true for controllers which are lacking in hierarchy support. The goal of this patch is two-fold. * Move users away from using hierarchy on currently non-hierarchical subsystems, so that implementing proper hierarchy support on those doesn't surprise them. * Keep track of which controllers are broken how and nudge the subsystems to implement proper hierarchy support. For now, start with a single warning message. We can whine louder later on. v2: Fixed a typo spotted by Michal. Warning message updated. v3: Updated memcg part so that it doesn't generate warning in the cases where .use_hierarchy=false doesn't make the behavior different from root.use_hierarchy=true.

This patch introduces a new representation for rational type numbers. The number will be expressed by specifying a numerator and denominator. For converting a raw value to a processed value multiply it by the numerator and divide it by the denominator. The reasoning for introducing this new type is that for a lot of devices the scale can be represented easily by a fractional number, but it is not possible to represent it as fixed point number without rounding. E.g. for a simple DAC the scale is often the reference voltage divided by the number of possible values (Usually 2**n_bits - 1). Each driver currently implements the conversion of this fraction to a fixed point number on its own. Also when it comes to the in-kernel interface this allows to directly use the fractional factors to convert a raw value to a processed value. This should on one hand require less instructions and on the other hand increase the precision.

This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts.

However, on some machines the overrides may do more harm than good due to configuration differences between machines with the same machine identifier. It turns out that it's possible for the bootloader to get the correct information on GOP-based systems, but we can't guarantee that the kernel's being booted with one that's been updated to do so. Add support for a capabilities flag that can be set by the bootloader, and skip the DMI checks in that case. Additionally, set this flag in the UEFI stub code.

The current dynamic debug code uses up to 3 recursion levels via %pV. This can consume quite a bit of stack. Directly call printk_emit to reduce the recursion depth. These changes include: dev_dbg: o Create and use function create_syslog_header to format the syslog header for printk_emit uses. o Call create_syslog_header and neaten __dev_printk o Make __dev_printk static not global o Remove include header declaration of __dev_printk o Remove now unused EXPORT_SYMBOL() of __dev_printk o Whitespace neatening dynamic_dev_dbg: o Remove KERN_DEBUG from dynamic_emit_prefix o Call create_syslog_header and printk_emit o Whitespace neatening Signed-off-by: Joe Perches Acked-by: David S.

Using multiple levels of %pV (a logging function with %pV that calls another logging function with %pV) can consume more stack than necessary.

Tsirkin" Date: Sun, 16 Sep 2012 11:50:30 +0300 Subject: KVM: make processes waiting on vcpu mutex killable vcpu mutex can be held for unlimited time so taking it with mutex_lock on an ioctl is wrong: one process could be passed a vcpu fd and call this ioctl on the vcpu used by another process, it will then be unkillable until the owner exits. Call mutex_lock_killable instead and return status. Note: mutex_lock_interruptible would be even nicer, but I am not sure all users are prepared to handle EINTR from these ioctls. They might misinterpret it as an error. Cleanup paths expect a vcpu that can't be used by any userspace so this will always succeed - catch bugs by calling BUG_ON. Catch callers that don't check return state by adding __must_check. Signed-off-by: Michael S.

With this patch we provide the functionality to initialize the Xen-SWIOTLB late in the bootup cycle - specifically for Xen PCI-frontend. We still will work if the user had supplied 'iommu=soft' on the Linux command line. Note: We cannot depend on after_bootmem to automatically determine whether this is early or not. This is because when PCI IOMMUs are initialized it is after after_bootmem but before a lot of "other" subsystems are initialized.

The AD5757/AD5737 only have current outputs, but for the AD5755/AD5757 each of the outputs can be configured to either be a voltage or a current output. We only allow to configure this at device probe time since usually this needs to match the external circuitry and should not be changed on the fly. A few trivial formatting changes on merge.

This adds a dependency between processor.h and cpuidle.h Although it is not a real problem, removing this dependency has the benefit of separating a bit more the cpuidle code from the rest of the acpi code. Also, the compilation should be a bit improved because we do no longer include cpuidle.h in processor.h. The preprocessor was generating 30418 loc and with this patch it generates 30256 loc for processor_thermal.c, a file which is not concerned at all by cpuidle, like processor_perflib.c and processor_throttling.c. That may sound ridiculous, but "small streams make big rivers" :P This patch moves this field into a static global per cpu variable like what is done in the intel_idle driver.

Build on audit_uid_comparator and audit_gid_comparator and replace audit_compare_id with audit_compare_uid and audit_compare_gid. This is one of those odd cases where being type safe and duplicating code leads to simpler shorter and more concise code. Don't allow bitmask operations in uid and gid comparisons in audit_data_to_entry. Bitmask operations are already denined in audit_rule_to_entry. Convert constants in audit_rule_to_entry and audit_data_to_entry into kuids and kgids when appropriate.

The quota on function is not converted because while it takes a quota type and an id. The id is the on disk quota format to use, which is something completely different. The signature of two struct quotactl_ops methods were changed to take struct kqid argumetns get_dqblk and set_dqblk. The dquot, xfs, and ocfs2 implementations of get_dqblk and set_dqblk are minimally changed so that the code continues to work with the change in parameter type. This is the first in a series of changes to always store quota identifiers in the kernel in struct kqid and only use raw type and qid values when interacting with on disk structures or userspace. Always using struct kqid internally makes it hard to miss places that need conversion to or from the kernel internal values.

When sending netlink broadcasts always convert uids and quota identifiers into the intial user namespace. There is as yet no way to send a netlink broadcast message with different contents to receivers in different namespaces, so for the time being just map all of the identifiers into the initial user namespace which preserves the current behavior. Change the callers of quota_send_warning in gfs2, xfs and dquot to generate a struct kqid to pass to quota send warning. When all of the user namespaces convesions are complete a struct kqid values will be availbe without need for conversion, but a conversion is needed now to avoid needing to convert everything at once.

Make minimal changes to dquot, quota_tree, quota_v1, quota_v2, ext3, ext4, and ocfs2 to deal with the change in quota structures and signatures. The ocfs2 changes are larger than most because of the extensive tracing throughout the ocfs2 quota code that prints out dq_id. quota_tree.c:get_index is modified to take a struct kqid instead of a qid_t because all of it's callers pass in dquot->dq_id and it allows me to introduce only a single conversion. The rest of the changes are either just replacing dq_type with dq_id.type, adding conversions to deal with the change in type and occassionally adding qid_eq to allow quota id comparisons in a user namespace safe way.

Handling the crash from a separate thread is helpful because: - Ability to call invoke rproc_report_crash() from atomic context, due to the fact that many crashes trigger an interrupt, so this function can be called directly from ISR context. - Avoiding deadlocks which could happen if rproc_report_crash() is called from a function which indirectly holds the rproc lock. Handling the crash might involve: - Remoteproc register dump - Remoteproc stack dump - Remoteproc core dump - Saving Remoteproc traces so they can be read after the crash - Reseting the remoteproc in order to make it functional again (hard recovery) Right now, we only print the crash type which was detected, and only the mmufault type is supported. Remoteproc low-level drivers can add more types when needed.

Other than the in-tree driver, the hypervisor driver actually cares about doing this only for the device where the debug is port actually in use, i.e. it needs to be told the coordinates of the device being reset (quite obviously, leveraging the addition done for that would likely benefit the in-tree driver too).

Commit c83ce989cb5f ("VFS: Fix the nfs sillyrename regression in kernel 2.6.38") was found to be the culprit. The nfs sillyrename fix used DCACHE_DISCONNECTED to indicate that the dentry was killed. This flag can be set on non-killed dentries too, which results in infinite retries when trying to traverse the dentry tree. This patch introduces a separate flag: DCACHE_DENTRY_KILLED, which is only set in d_kill() and makes try_to_ascend() test only this flag. IBM reported successful test results with this patch.

Currently this is done each time the control is accessed. And while the performance impact of this should be negligible we can easily do better. The roundup_pow_of_two macro performs the same calculation which is currently done manually, but it is also possible to use this macro with compile time constants and so it can be used to initialize static data. So we can use it to initialize the mask field of a ENUM control during its declaration.

Research on the web suggests that the warning disappears if '>' instead of '>=' is used for the comparison. Tests after changing the macro along that line show that the warning is gone, and that the result is still correct: i=-4: DIV_ROUND_CLOSEST(i, 2)=-2 i=-3: DIV_ROUND_CLOSEST(i, 2)=-2 i=-2: DIV_ROUND_CLOSEST(i, 2)=-1 i=-1: DIV_ROUND_CLOSEST(i, 2)=-1 i=0: DIV_ROUND_CLOSEST(i, 2)=0 i=1: DIV_ROUND_CLOSEST(i, 2)=1 i=2: DIV_ROUND_CLOSEST(i, 2)=1 i=3: DIV_ROUND_CLOSEST(i, 2)=2 i=4: DIV_ROUND_CLOSEST(i, 2)=2 Code size is the same as before.

By accumulating a frame worth of data before passing it on, the latency can be dramatically reduced. As a side effect, the special EV_SYN handling can be removed, since the frame is now atomic. This patch adds the events() handler callback and uses it if it exists. The latency is improved by 50 us even without the callback.

" If insufficient fragments are received to complete reassembly of a packet within 60 seconds of the reception of the first-arriving fragment of that packet, reassembly of that packet must be abandoned and all the fragments that have been received for that packet must be discarded. If the first fragment (i.e., the one with a Fragment Offset of zero) has been received, an ICMP Time Exceeded -- Fragment Reassembly Time Exceeded message should be sent to the source of that fragment. " As Herbert suggested, we could actually use the standard IPv6 reassembly code which follows RFC2460. With this patch applied, I can see ICMP Time Exceeded sent from the receiver when the sender sent out 3/4 fragmented IPv6 UDP packet.

The interrupt controller, or the HW block containing it, is referred to occasionally as "armctrl" in the SoC documentation, hence the symbol naming in the code. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved implementation to drivers/irchip/. * Added devicetree documentation, and hence removed list of IRQs from bcm2835.dtsi. * Changed shift in MAKE_HWIRQ() and HWIRQ_BANK() from 8 to 5 to reduce the size of the hwirq space, and pass the total size of the hwirq space to irq_domain_add_linear(), rather than just the number of valid hwirqs; the two are different due to the hwirq space being sparse. * Added the interrupt controller DT node to the top-level of the DT, rather than nesting it inside a /axi node. Hence, changed the reg value since /axi had a ranges property. This seems simpler to me, but I'm not sure if everyone will like this change or not. * Don't set struct irq_domain_ops.map = irq_domain_simple_map, hence removing the need to patch include/linux/irqdomain.h or kernel/irq/irqdomain.c. * Simplified armctrl_of_init() using of_iomap(). * Removed unused IS_VALID_BANK()/IS_VALID_IRQ() macros. * Renamed armctrl_handle_irq() to prevent possible symbol clashes. * Made armctrl_of_init() static. * Removed comment "Each bank is registered as a separate interrupt controller" since this is no longer true. * Removed FSF address from license header. * Added my name to copyright header.

Each channel has an output compare register, which is compared against the 32 least significant bits of the free running counter values, and generates an interrupt. Timer 3 is used as the Linux timer. The BCM2835 also contains an SP804-based timer module.

One major advantage, other than unifying the page tracking structures, this offers is that we replace the vmalloc'ed array (which can be up to a megabyte in size) with a chain of individual pages which helps reduce memory pressure. The disadvantage is that we then do not have a simple array to iterate, or to access randomly. The common case for this is in the relocation processing, which will typically fit within a single scatterlist page and so be almost the same cost as the simple array. For iterating over the array, the extra function call could be optimised away, but in reality is an insignificant cost of either binding the pages, or performing the pwrite/pread. v2: Fix drm_clflush_sg() to not invoke wbinvd as well! And fix the trivial compile error from rebasing.

Adding support for RTNL childs involved refactoring of ipoib_vlan_add which is now used by both the sysfs and the link_ops code. Also, added ndo_uninit entry to support calling unregister_netdevice_queue from the rtnl dellink entry. This required removal of calls to ipoib_dev_cleanup from the driver in flows which use unregister_netdevice, since the networking core will invoke ipoib_uninit which does exactly that.

If a user creates a new state or updates an existing one but does not supply the bytes for the whole ESN replay window, the kernel copies random heap bytes into the replay bitmap, the ones happen to follow the XFRMA_REPLAY_ESN_VAL netlink attribute. This leads to following issues: 1. The replay window has random bits set confusing the replay handling code later on. 2. A malicious user could use this flaw to leak up to ~3.5kB of heap memory when she has access to the XFRM netlink interface (requires CAP_NET_ADMIN). Known users of the ESN replay window are strongSwan and Steffen's iproute2 patch (). The latter uses the interface with a bitmap supplied while the former does not. strongSwan is therefore prone to run into issue 1. To fix both issues without breaking existing userland allow using the XFRMA_REPLAY_ESN_VAL netlink attribute with either an empty bitmap or a fully specified one. For the former case we initialize the in-kernel bitmap with zero, for the latter we copy the user supplied bitmap. For state updates the full bitmap must be supplied. To prevent overflows in the bitmap length calculation the maximum size of bmp_len is limited to 128 by this patch -- resulting in a maximum replay window of 4096 packets. This should be sufficient for all real life scenarios (RFC 4303 recommends a default replay window size of 64).

This change adds a new interface, AcpiDecodePldBuffer that parses the buffer into a more usable local struct. Also adds macros to both get and set individual fields within the packed _PLD buffer. Adds a new include file, acbuffer.h - which will be expanded to add structs for other ACPI names that return buffers. ACPICA BZ 954. Emit (in comments) the decoded contents of a static _PLD buffer in order to improve comprehension of this bit-packed buffer. Add multi-endian support to the _PLD decode routine. Deploy the multi-endian macros to extract data from the _PLD buffer.

Since Xen-4.2, hvm domains may have portions of their memory paged out. When a foreign domain (such as dom0) attempts to map these frames, the map will initially fail. The hypervisor returns a suitable errno, and kicks an asynchronous page-in operation carried out by a helper. The foreign domain is expected to retry the mapping operation until it eventually succeeds. The foreign domain is not put to sleep because itself could be the one running the pager assist (typical scenario for dom0). This patch adds support for this mechanism for backend drivers using grant mapping and copying operations. Specifically, this covers the blkback and gntdev drivers (which map foreign grants), and the netback driver (which copies foreign grants). * Add a retry method for grants that fail with GNTST_eagain (i.e. because the target foreign frame is paged out). * Insert hooks with appropriate wrappers in the aforementioned drivers. The retry loop is only invoked if the grant operation status is GNTST_eagain. It guarantees to leave a new status code different from GNTST_eagain. Any other status code results in identical code execution as before. The retry loop performs 256 attempts with increasing time intervals through a 32 second period. It uses msleep to yield while waiting for the next retry. V2 after feedback from David Vrabel: * Explicit MAX_DELAY instead of wrap-around delay into zero * Abstract GNTST_eagain check into core grant table code for netback module. V3 after feedback from Ian Campbell: * Add placeholder in array of grant table error descriptions for unrelated error code we jump over. * Eliminate single map and retry macro in favor of a generic batch flavor. * Some renaming. * Bury most implementation in grant_table.c, cleaner interface. V4 rebased on top of sync of Xen grant table interface headers.

This is intended to mimic the model of a swap disk, where a disk read is non-destructive. Unlike a disk, however, freeing up the RAM can be valuable. Over the years that frontswap was in the review process, several reviewers (and notably Hugh Dickins in 2010) pointed out that this would result, at least temporarily, in two copies of the data in RAM: one (compressed for zcache) copy in tmem, and one copy in the swap cache. We wondered if this could be done differently, at least optionally. This patch allows tmem backends to instruct the frontswap code that this backend performs exclusive gets. Zcache2 already contains hooks to support this feature. Other backends are completely unaffected unless/until they are updated to support this feature. While it is not clear that exclusive gets are a performance win on all workloads at all times, this small patch allows for experimentation by backends. P.S. Let's not quibble about the naming of "get" vs "read" vs "load" etc. The naming is currently horribly inconsistent between cleancache and frontswap and existing tmem backends, so will need to be straightened out as a separate patch. "Get" is used by the tmem architecture spec, existing backends, and all documentation and presentation material so I am using it in this patch.

ACPI _UPC and _PLD can help to resolve this issue and so it is necessary to bind USB with ACPI. This patch is to allow ACPI binding with USB-3.0 hub. Current ACPI only can bind one struct-device to one ACPI device node. This can not work with USB-3.0 hub, because the USB-3.0 hub has two logical devices. Each works for USB-2.0 and USB-3.0 devices. In the Linux USB subsystem, those two logical hubs are treated as two seperate devices that have two struct devices. But in the ACPI DSDT, these two logical hubs share one ACPI device node. So there is a requirement to bind multi struct-devices to one ACPI device node. This patch is to resolve such problem. Following is the ACPI device nodes' description under xhci hcd.

Previously we were always taking an RTT sample in tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we receive the SYN. So for TFO we must wait until tcp_rcv_state_process() to take the RTT sample. To fix this, we wait until after TFO calls tcp_v4_syn_recv_sock() before we set the snt_synack timestamp, since tcp_synack_rtt_meas() already ensures that we only take a SYNACK RTT sample if snt_synack is non-zero.

When specified, a new resamplefd is provided that notifies the user when the irqchip has been resampled by the VM. This may, for instance, indicate an EOI. Also in this mode, posting of an interrupt through an irqfd only asserts the interrupt. On resampling, the interrupt is automatically de-asserted prior to user notification. This enables level triggered interrupts to be posted and re-enabled from vfio with no userspace intervention. All resampling irqfds can make use of a single irq source ID, so we reserve a new one for this interface.

If the interrupt occurs from idle, then lockdep-RCU will complain about such uses, as they appear to be illegal uses of RCU from the idle loop. In other environments, RCU_NONIDLE() could be used to properly protect the use of RCU, but RCU_NONIDLE() currently cannot be invoked except from process context. This commit therefore modifies RCU_NONIDLE() to permit its use more globally. Reported-by: Steven Rostedt Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.

McKenney" Date: Thu, 23 Aug 2012 08:34:07 -0700 Subject: time: RCU permitted to stop idle entry via softirq The can_stop_idle_tick() function complains if a softirq vector is raised too late in the idle-entry process, presumably in order to prevent dangling softirq invocations from being delayed across the full idle period, which might be indefinitely long -- and if softirq was asserted any later than the call to this function, such a delay might well happen. However, RCU needs to be able to use softirq to stop idle entry in order to be able to drain RCU callbacks from the current CPU, which in turn enables faster entry into dyntick-idle mode, which in turn reduces power consumption. Because RCU takes this action at a well-defined point in the idle-entry path, it is safe for RCU to take this approach. This commit therefore silences the error message that is sometimes produced when the going-idle CPU suddenly finds that it has an RCU_SOFTIRQ to process. The error message will continue to be issued for other softirq vectors. Reported-by: Sedat Dilek Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.

This MFD patch supports the I2C communication using the regmap, the interrupt handling using the linear IRQ domain and configurable platform data structures for each driver module. (Driver Architecture) < mfd devices > LP8788 HW .......... mfd .......... regulator drivers I2C power supply driver IRQs iio adc driver rtc driver backlight driver current sink drivers o regulators : LDOs and BUCKs o power supply : Battery charger o iio adc : Battery voltage/temperature o rtc : RTC and alarm o backlight o current sink : LED and vibrator All MFD device modules are registered by LP8788 MFD core driver. For sharing information such like the virtual IRQ number, MFD core driver uses the resource structure. Then each module can retrieve the specific IRQ number and detect it in the IRQ thread. Configurable platform data is handled in each driver module.

This PHY needs additional setup if it is strapped for address 0. In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by: Marek Vasut Cc: David J. Choi Cc: David S.

This page is used to build fragments for skbs. Its done to increase probability of coalescing small write() into single segments in skbs still in write queue (not yet sent) But it wastes a lot of memory for applications handling many mostly idle sockets, since each socket holds one page in sk->sk_sndmsg_page Its also quite inefficient to build TSO 64KB packets, because we need about 16 pages per skb on arches where PAGE_SIZE = 4096, so we hit page allocator more than wanted. This patch adds a per task frag allocator and uses bigger pages, if available. An automatic fallback is done in case of memory pressure. (up to 32768 bytes per frag, thats order-3 pages on x86) This increases TCP stream performance by 20% on loopback device, but also benefits on other network devices, since 8x less frags are mapped on transmit and unmapped on tx completion. Alexander Duyck mentioned a probable performance win on systems with IOMMU enabled. Its possible some SG enabled hardware cant cope with bigger fragments, but their ndo_start_xmit() should already handle this, splitting a fragment in sub fragments, since some arches have PAGE_SIZE=65536 Successfully tested on various ethernet devices.

This commit therefore adds rcu_user_enter() and rcu_user_exit(), which allow non-idle tasks to enter RCU idle mode. These are quite similar to rcu_idle_enter() and rcu_idle_exit(), respectively, except that they omit the idle-task checks.

In this case, the current CPU would enter the IPI handler in userspace-RCU-idle mode, but would need to exit the IPI handler after having exited that mode. To allow this to work, this commit adds two new APIs to TREE_RCU: - rcu_user_enter_after_irq(). This must be called from an interrupt between rcu_irq_enter() and rcu_irq_exit(). After the irq calls rcu_irq_exit(), the irq handler will return into an RCU extended quiescent state. In theory, this interrupt is never a nested interrupt, but in practice it might interrupt softirq, which looks to RCU like a nested interrupt. - rcu_user_exit_after_irq(). This must be called from a non-nesting interrupt, interrupting an RCU extended quiescent state, also between rcu_irq_enter() and rcu_irq_exit(). After the irq calls rcu_irq_exit(), the irq handler will return in an RCU non-quiescent state.

It is currently x86-only, but that restriction will be removed in a subsequent patch. Unfortunately, the kernel checksyscalls script had a bug which suppressed any warning to other architectures that the kcmp syscall was not implemented. A patch to checksyscalls is being tested in linux-next and other architectures are seeing warnings about kcmp being unimplemented. This patch adds __NR_kcmp to so that kcmp is wired in for architectures using the generic syscall list.

I.e. when booting with console=ttyAMA0 kgdboc=ttyAMA0, everything works fine, but with console=ttyFOO kgdboc=ttyAMA0, the kgdboc doesn't work. This is because we don't initialize the hardware. Calling ->startup() is not an option, because drivers request interrupts there, and drivers fail to handle situations when tty isn't opened with interrupts enabled. So, we have to implement a new callback (actually, tty_ops already have a similar callback), which does everything needed to initialize just the hardware.

Unlike KDB's disable_nmi command, with this driver you are always able to go back to the debugger using KGDB escape sequence ($3#33). This is because this console driver processes the input in NMI context, and thus is able to intercept the magic sequence. Note that since the console interprets input and uses polling communication methods, for things like PPP it is still better to fully detach debugger port from the KGDB NMI (i.e. disable_nmi), and use raw console. Usually, to enter the debugger one have to type the magic sequence, so initially the kernel will print the following prompt on the NMI debugger console: Type $3#33 to enter the debugger> For convenience, there is a kgdb_fiq.knock kernel command line option, when set to 0, this turns the special command to just a return key press, so the kernel will be printing this: Hit to enter the debugger> This is more convenient for long debugging sessions, although it makes nmi_console feature somewhat useless. And for the cases when NMI connected to a dedicated button, the knocking can be disabled altogether by setting kgdb_fiq.knock to -1.

Section 4.2. Default Tunnel Egress Behaviour. o If the inner ECN field is Not-ECT, the decapsulator MUST NOT propagate any other ECN codepoint onwards. This is because the inner Not-ECT marking is set by transports that rely on dropped packets as an indication of congestion and would not understand or respond to any other ECN codepoint [RFC4774]. Specifically: * If the inner ECN field is Not-ECT and the outer ECN field is CE, the decapsulator MUST drop the packet. * If the inner ECN field is Not-ECT and the outer ECN field is Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the outgoing packet with the ECN field cleared to Not-ECT. This patch moves the ECN decap logic out of the individual tunnels into a common place. It also adds logging to allow detecting broken systems that set ECN bits incorrectly when tunneling (or an intermediate router might be changing the header). Overloads rx_frame_error to keep track of ECN related error. Thanks to Chris Wright who caught this while reviewing the new VXLAN tunnel. This code was tested by injecting faulty logic in other end GRE to send incorrectly encapsulated packets. Signed-off-by: Stephen Hemminger Signed-off-by: David S.

However, ACPI 5.0 (which introduces the BGRT) recommends putting the logo image in EFI boot services memory, so that the OS can reclaim that memory. Production systems follow this recommendation, breaking the ACPI BGRT driver. Move the bulk of the BGRT code to run during a new EFI late initialization phase, which occurs after switching EFI to virtual mode, and after initializing ACPI, but before freeing boot services memory. Copy the BIOS logo image to kernel memory at that point, and make it accessible to the BGRT driver. Rework the existing ACPI BGRT driver to act as a simple wrapper exposing that image (and the properties from the BGRT) via sysfs.

Introduce the basic SR-IOV parvirtualization context objects for multiplexing and demultiplexing MADs. 2. Introduce support for the new proxy and tunnel QP types. This patch introduces the objects required by the master for managing QP paravirtualization for guests. struct mlx4_ib_sriov is created by the master only. It is a container for the following: 1. All the info required by the PPF to multiplex and de-multiplex MADs (including those from the PF). (struct mlx4_ib_demux_ctx demux) 2. All the info required to manage alias GUIDs (i.e., the GUID at index 0 that each guest perceives. In fact, this is not the GUID which is actually at index 0, but is, in fact, the GUID which is at index[] in the physical table. 3. structures which are used to manage CM paravirtualization 4. structures for managing the real special QPs when running in SR-IOV mode. The real SQPs are controlled by the PPF in this case. All SQPs created and controlled by the ib core layer are proxy SQP. struct mlx4_ib_demux_ctx contains the information per port needed to manage paravirtualization: 1. All multicast paravirt info 2. All tunnel-qp paravirt info for the port. 3. GUID-table and GUID-prefix for the port 4. work queues. struct mlx4_ib_demux_pv_ctx contains all the info for managing the paravirtualized QPs for one slave/port. struct mlx4_ib_demux_pv_qp contains the info need to run an individual QP (either tunnel qp or real SQP). Note: We made use of the 2 most significant bits in enum mlx4_ib_qp_flags (based on enum ib_qp_create_flags in ib_verbs.h). We need these bits in the low-level driver for internal purposes.

This is performed the master detects that a slave has started up (MLX4_DEV_EVENT_SLAVE_INIT event generated when a slave initializes its comm channel). For the master, there is no such startup event, so it creates its own tunneling resources when it starts up. In addition, the master also creates the real special QPs.

The guest then did offset calculations on the sqp_base qp number that the PPF passed to it in QUERY_FUNC_CAP(). This is now changed so that the guest does no offset calculations regarding proxy or tunnel QPs to use. This change frees the PPF from needing to adhere to a specific order in allocating proxy and tunnel QPs. Now QUERY_FUNC_CAP provides each port individually with its proxy qp0, proxy qp1, tunnel qp0, and tunnel qp1 QP numbers, and these are used directly where required (with no offset calculations). To accomplish this change, several fields were added to the phys_caps structure for use by the PPF and by non-SR-IOV mode: base_sqpn -- in non-sriov mode, this was formerly sqp_start. base_proxy_sqpn -- the first physical proxy qp number -- used by PPF base_tunnel_sqpn -- the first physical tunnel qp number -- used by PPF. The current code in the PPF still adheres to the previous layout of sqps, proxy-sqps and tunnel-sqps. However, the PPF can change this layout without affecting VF or (paravirtualized) PF code.

This is a problem that shows up when userspace is using a drm plane to implement a hw cursor.. making overlay disable synchronous causes a performance problem when x11 is rapidly enabling/disabling the hw cursor. But not making it synchronous opens up a race condition for crashing if userspace turns around and immediately deletes the fb. Refcnt'ing the fb makes it possible to solve this problem. v1: original v2: add drm_framebuffer_remove() which is called in all paths where fb->funcs->destroy() was directly called before. This cleans up the CRTCs/planes that the fb was attached to.

As the headers are split the entries will be transferred across from the old Kbuild files to the UAPI Kbuild files. The changes made in this commit are: (1) Exported generated files (of which there are currently four) are moved to uapi/ directories under the appropriate generated/ directory, thus we get: include/generated/uapi/linux/version.h arch/x86/include/generated/uapi/asm/unistd_32.h arch/x86/include/generated/uapi/asm/unistd_64.h arch/x86/include/generated/uapi/asm/unistd_x32.h These paths were added to the build as -I flags in a previous patch. (2) scripts/Makefile.headersinst is now given the UAPI path to install from rather than the old path. It then determines the old path from that and includes that Kbuild also if it exists, thus permitting the headers to exist in either directory during the changeover. I also renamed the "install" variable to "installdir" as it refers to a directory not the install program. (3) scripts/headers_install.pl is altered to take a list of source file paths instead of just their names so that the makefile can tell it exactly where to find each file. For the moment, files can be obtained from one of four places for each output directory: .../include/uapi/foo/ .../include/generated/uapi/foo/ .../include/foo/ .../include/generated/foo/ The non-UAPI paths will be dropped later.

The patch adds a generic implementation which calls do_sendfile() directly and avoids set_fs(). The sparc architecture has wrappers for the sign extensions while powerpc relies on the compiler to do the this. The patch adds wrappers for powerpc to handle the u32->int type conversion. compat_sys_sendfile64() can be replaced by a sys_sendfile() call since compat_loff_t has the same size as off_t on a 64-bit system. On powerpc, the patch also changes the 64-bit sendfile call from sys_sendile64 to sys_sendfile. Signed-off-by: Catalin Marinas Acked-by: David S.

This was hard to reproduce but the symptom was that packets were delivered to local host instead of being forwarded. David suggested to add fib_type to fib_info so that we dont inadvertently share same fib_info for different purposes. With help from Julian Anastasov who provided very helpful hints, reproduced here : Can it be a problem related to fib_info reuse from different routes. For example, when local IP address is created for subnet we have: broadcast 192.168.0.255 dev DEV proto kernel scope link src 192.168.0.1 192.168.0.0/24 dev DEV proto kernel scope link src 192.168.0.1 local 192.168.0.1 dev DEV proto kernel scope host src 192.168.0.1 The "dev DEV proto kernel scope link src 192.168.0.1" is a reused fib_info structure where we put cached routes. The result can be same fib_info for 192.168.0.255 and 192.168.0.0/24. RTN_BROADCAST is cached only for input routes. Incoming broadcast to 192.168.0.255 can be cached and can cause problems for traffic forwarded to 192.168.0.0/24. So, this patch should solve the problem because it separates the broadcast from unicast traffic. And the ip_route_input_slow caching will work for local and broadcast input routes (above routes 1 and 3) just because they differ in scope and use different fib_info. Many thanks to Chris Clayton for his patience and help.

After connection is established, path1 is not available, thus this path is marked as inactive. Then traffic goes through path2, but for some reasons packets are delayed (after rto.max). Because packets are delayed, the retransmit mechanism will switch again to path1. At this time, we receive a delayed SACK from path2. When we update the state of the path in sctp_check_transmitted(), we do not take into account the source address of the SACK, hence we update the wrong path.

For example a custom algorithm could be used to manage alignment requirements. As I can't predict all the possible requirements/needs for all allocation uses cases, I add a "free" field 'void *data' to pass any needed information to the allocation function. For example 'data' could be used to handle a structure where you store the alignment, the expected memory bank, the requester device, or any information that could influence the allocation algorithm. An usage example may look like this: struct my_pool_constraints { int align; int bank; ... }; unsigned long my_custom_algo(unsigned long *map, unsigned long size, unsigned long start, unsigned int nr, void *data) { struct my_pool_constraints *constraints = data; ... deal with allocation contraints ... return the index in bitmap where perform the allocation } void create_my_pool() { struct my_pool_constraints c; struct gen_pool *pool = gen_pool_create(...); gen_pool_add(pool, ...); gen_pool_set_algo(pool, my_custom_algo, &c); } Add of best-fit algorithm function: most of the time best-fit is slower then first-fit but memory fragmentation is lower. The random buffer allocation/free tests don't show any arithmetic relation between the allocation time and fragmentation but the best-fit algorithm is sometime able to perform the allocation when the first-fit can't. This new algorithm help to remove static allocations on ESRAM, a small but fast on-chip RAM of few KB, used for high-performance uses cases like DMA linked lists, graphic accelerators, encoders/decoders. On the Ux500 (in the ARM tree) we have define 5 ESRAM banks of 128 KB each and use of static allocations becomes unmaintainable: cd arch/arm/mach-ux500 && grep -r ESRAM . ./include/mach/db8500-regs.h:/* Base address and bank offsets for ESRAM */ ./include/mach/db8500-regs.h:#define U8500_ESRAM_BASE 0x40000000 ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK_SIZE 0x00020000 ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK0 U8500_ESRAM_BASE ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK1 (U8500_ESRAM_BASE + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK2 (U8500_ESRAM_BANK1 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK3 (U8500_ESRAM_BANK2 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK4 (U8500_ESRAM_BANK3 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_DMA_LCPA_OFFSET 0x10000 ./include/mach/db8500-regs.h:#define U8500_DMA_LCPA_BASE (U8500_ESRAM_BANK0 + U8500_ESRAM_DMA_LCPA_OFFSET) ./include/mach/db8500-regs.h:#define U8500_DMA_LCLA_BASE U8500_ESRAM_BANK4 I want to use genalloc to do dynamic allocations but I need to be able to fine tune the allocation algorithm.

If pins are on a GPIO device which gets its base GPIO number assigned dynamically at run-time, the values can't be hard-coded. In that case, let the caller tell i2c-mux-gpio the name of the GPIO chip and the (relative) GPIO pin numbers to use. At probe time, the i2c-mux-gpio driver will look for the chip and apply the proper offset to turn relative GPIO pin numbers to absolute GPIO pin numbers. The same could be (and was so far) done on the caller's end, however doing it in i2c-mux-gpio has two benefits: * It avoids duplicating the code on every caller's side (about 30 lines of code.) * It allows for deferred probing for the muxed part of the I2C bus only. If finding the GPIO chip is the caller's responsibility, then deferred probing (if the GPIO chip isn't there yet) will not only affect the mux and the I2C bus segments behind it, but also the I2C bus trunk.

Expectation is that the driver reserves the memory attributes for the pfn before calling vm_insert_pfn(). remap_pfn_range() (when called for the whole vma) will setup a new attribute (based on the prot argument) for the specified pfn range. This addresses the legacy usage which typically calls remap_pfn_range() with a desired memory attribute. For ranges smaller than the vma size (which is typically not the case), remap_pfn_range() will use the existing memory attribute for the pfn range. Expose two different API's for these different behaviors. track_pfn_insert() for tracking the pfn attribute set by vm_insert_pfn() and track_pfn_remap() for the remap_pfn_range(). This cleanup also prepares the ground for the track/untrack pfn vma routines to take over the ownership of setting PAT specific vm_flag in the 'vma'.

VM_MIXEDMAP VMA can mix pure-pfn ptes, special ptes and normal ptes. Now copy_page_range() always copies VM_MIXEDMAP VMA on fork like VM_PFNMAP. If driver populates whole VMA at mmap() it probably not expects page-faults. This patch removes special check from vma_wants_writenotify() which disables pages write tracking for VMA populated via vm_instert_page(). BDI below mapped file should not use dirty-accounting, moreover do_wp_page() can handle this. vm_insert_page() still marks vma after first usage. Usually it is called from f_op->mmap() handler under mm->mmap_sem write-lock, so it able to change vma->vm_flags. Caller must set VM_MIXEDMAP at mmap time if it wants to call this function from other places, for example from page-fault handler.

Usually binfmt module sets mm->exe_file and mmaps executable vmas with this file, they hold mm->exe_file while task is running. comment from v2.6.25-6245-g925d1c4 ("procfs task exe symlink"), where all this stuff was introduced: > The kernel implements readlink of /proc/pid/exe by getting the file from > the first executable VMA.

This avoids pinning the mounted filesystem. exe_file's vma accounting is hooked into every file mmap/unmmap and vma split/merge just to fix some hypothetical pinning fs from umounting by mm, which already unmapped all its executable files, but still alive. Seems like currently nobody depends on this behaviour. We can try to remove this logic and keep mm->exe_file until final mmput(). mm->exe_file is still protected with mm->mmap_sem, because we want to change it via new sys_prctl(PR_SET_MM_EXE_FILE). Also via this syscall task can change its mm->exe_file and unpin mountpoint explicitly.

I noticed a lot of possible speed improvements, which I am now proposing in this patch set. Patches 1-4 are preparatory: remove internal functions from rbtree.h so that users won't be tempted to use them instead of the documented APIs, clean up some incorrect usages I've noticed (in particular, with the recently added fs/proc/proc_sysctl.c rbtree usage), reference the documentation so that people have one less excuse to miss it, etc. Patch 5 is a small module I wrote to check the rbtree performance. It creates 100 nodes with random keys and repeatedly inserts and erases them from an rbtree. Additionally, it has code to check for rbtree invariants after each insert or erase operation. Patches 6-12 is where the rbtree optimizations are done, and they touch only that one file, lib/rbtree.c . I am getting good results out of these - in my small benchmark doing rbtree insertion (including search) and erase, I'm seeing a 30% runtime reduction on Sandybridge E5, which is more than I initially thought would be possible. (the results aren't as impressive on my two other test hosts though, AMD barcelona and Intel Westmere, where I am seeing 14% runtime reduction only). The code size - both source (ommiting comments) and compiled - is also shorter after these changes. However, I do admit that the updated code is more arduous to read - one big reason for that is the removal of the tree rotation helpers, which added some overhead but also made it easier to reason about things locally. Overall, I believe this is an acceptable compromise, given that this code doesn't get modified very often, and that I have good tests for it. Upon Peter's suggestion, I added comments showing the rtree configuration before every rotation. I think they help; however it's still best to have a copy of the cormen/leiserson/rivest book when digging into this code. This patch: reference Documentation/rbtree.txt for usage instructions include/linux/rbtree.h included some basic usage instructions, while Documentation/rbtree.txt had some more complete and easier to follow instructions. Replacing the former with a reference to the latter.

We can make use of this property to simplify the code emitted by the RB_EMPTY_NODE and RB_CLEAR_NODE macros. Also, we can get rid of the rb_init_node function which had been introduced by commit 88d19cf37952 ("timers: Add rb_init_node() to allow for stack allocated rb nodes") to avoid some issue with the empty node's color not being initialized. I'm not sure what the RB_EMPTY_NODE checks in rb_prev() / rb_next() are doing there, though. axboe introduced them in commit 10fd48f2376d ("rbtree: fixed reversed RB_EMPTY_NODE and rb_next/prev"). The way I see it, the 'empty node' abstraction is only used by rbtree users to flag nodes that they haven't inserted in any rbtree, so asking the predecessor or successor of such nodes doesn't make any sense. One final rb_init_node() caller was recently added in sysctl code to implement faster sysctl name lookups. This code doesn't make use of RB_EMPTY_NODE at all, and from what I could see it only called rb_init_node() under the mistaken assumption that such initialization was required before node insertion.

A new callback is added to the rbtree insertion and erase rebalancing functions, to be called on each tree rotations. Such rotations preserve the subtree's root augmented value, but require recalculation of the one child that was previously located at the subtree root. In the insertion case, the handcoded search phase must be updated to maintain the augmented information on insertion, and then the rbtree coloring/rebalancing algorithms keep it up to date. In the erase case, things are more complicated since it is library code that manipulates the rbtree in order to remove internal nodes. This requires a couple additional callbacks to copy a subtree's augmented value when a new root is stitched in, and to recompute augmented values down the ancestry path when a node is removed from the tree. In order to preserve maximum speed for the non-augmented case, we provide two versions of each tree manipulation function. rb_insert_augmented() is the augmented equivalent of rb_insert_color(), and rb_erase_augmented() is the augmented equivalent of rb_erase().

It also adds synthetic tests to compare the performance of interval trees vs prio trees. Short answers is that interval trees are slightly faster (~25%) on insert/erase, and much faster (~2.4 - 3x) on search. It is debatable how realistic the synthetic test is, and I have not made such measurements yet, but my impression is that interval trees would still come out faster. Patch 2 uses a preprocessor template to make the interval tree generic, and uses it as a replacement for the vma prio_tree. Patch 3 takes the other prio_tree user, kmemleak, and converts it to use a basic rbtree. We don't actually need the augmented rbtree support here because the intervals are always non-overlapping. Patch 4 removes the now-unused prio tree library. Patch 5 proposes an additional optimization to rb_erase_augmented, now providing it as an inline function so that the augmented callbacks can be inlined in. This provides an additional 5-10% performance improvement for the interval tree insert/erase benchmark. There is a maintainance cost as it exposes augmented rbtree users to some of the rbtree library internals; however I think this cost shouldn't be too high as I expect the augmented rbtree will always have much less users than the base rbtree. I should probably add a quick summary of why I think it makes sense to replace prio trees with augmented rbtree based interval trees now. One of the drivers is that we need augmented rbtrees for Rik's vma gap finding code, and once you have them, it just makes sense to use them for interval trees as well, as this is the simpler and more well known algorithm. prio trees, in comparison, seem *too* clever: they impose an additional 'heap' constraint on the tree, which they use to guarantee a faster worst-case complexity of O(k+log N) for stabbing queries in a well-balanced prio tree, vs O(k*log N) for interval trees (where k=number of matches, N=number of intervals). Now this sounds great, but in practice prio trees don't realize this theorical benefit. First, the additional constraint makes them harder to update, so that the kernel implementation has to simplify things by balancing them like a radix tree, which is not always ideal. Second, the fact that there are both index and heap properties makes both tree manipulation and search more complex, which results in a higher multiplicative time constant. As it turns out, the simple interval tree algorithm ends up running faster than the more clever prio tree. This patch: Add two test modules: - prio_tree_test measures the performance of lib/prio_tree.c, both for insertion/removal and for stabbing searches - interval_tree_test measures the performance of a library of equivalent functionality, built using the augmented rbtree support. In order to support the second test module, lib/interval_tree.c is introduced. It is kept separate from the interval_tree_test main file for two reasons: first we don't want to provide an unfair advantage over prio_tree_test by having everything in a single compilation unit, and second there is the possibility that the interval tree functionality could get some non-test users in kernel over time.

The algorithms are similar to lib/interval_tree.c; however that code can't be directly reused as the interval endpoints are not explicitly stored in the VMA. So instead, the common algorithm is moved into a template and the details (node type, how to get interval endpoints from the node, etc) are filled in using the C preprocessor. Once the interval tree functions are available, using them as a replacement to the VMA prio tree is a relatively simple, mechanical job.

Changes: - fixed 'endpoing' typo noticed by Andrew Morton - replaced include/linux/interval_tree_tmpl.h, which was used as a template (including it automatically defined the interval tree functions) with include/linux/interval_tree_generic.h, which only defines a preprocessor macro INTERVAL_TREE_DEFINE(), which itself defines the interval tree functions when invoked. Now that is a very long macro which is unfortunate, but it does make the usage sites (lib/interval_tree.c and mm/interval_tree.c) a bit nicer than previously. - make use of RB_DECLARE_CALLBACKS() in the INTERVAL_TREE_DEFINE() macro, instead of duplicating that code in the interval tree template. - replaced vma_interval_tree_add(), which was actually handling the nonlinear and interval tree cases, with vma_interval_tree_insert_after() which handles only the interval tree case and has an API that is more consistent with the other interval tree handling functions. The nonlinear case is now handled explicitly in kernel/fork.c dup_mmap().

Instead, the avc's were ordered in such a way that the origin vma was always visited by rmap before the destination. This ordering and the use of page table locks rmap usage safe. However, we want to replace the use of linked lists in anon rmap with an interval tree, and this will make it harder to impose such ordering as the interval tree will always be sorted by the avc->vma->vm_pgoff value. For now, let's replace the anon_vma_moveto_tail() ordering function with proper anon_vma locking in move_ptes(). Once we have the anon interval tree in place, we will re-introduce an optimization to avoid taking these locks in the most common cases.

When a large VMA (anon or private file mapping) is first touched, which will populate its anon_vma field, and then split into many regions through the use of mprotect(), the original anon_vma ends up linking all of the vmas on a linked list. This can cause rmap to become inefficient, as we have to walk potentially thousands of irrelevent vmas before finding the one a given anon page might fall into. By replacing the same_anon_vma linked list with an interval tree (where each avc's interval is determined by its vma's start and last pgoffs), we can make rmap efficient for this use case again. While the change is large, all of its pieces are fairly simple. Most places that were walking the same_anon_vma list were looking for a known pgoff, so they can just use the anon_vma_interval_tree_foreach() interval tree iterator instead. The exception here is ksm, where the page's index is not known. It would probably be possible to rework ksm so that the index would be known, but for now I have decided to keep things simple and just walk the entirety of the interval tree there. When updating vma's that already have an anon_vma assigned, we must take care to re-index the corresponding avc's on their interval tree. This is done through the use of anon_vma_interval_tree_pre_update_vma() and anon_vma_interval_tree_post_update_vma(), which remove the avc's from their interval tree before the update and re-insert them after the update. The anon_vma stays locked during the update, so there is no chance that rmap would miss the vmas that are being updated.

When the destination VMA is placed after the original in rmap traversal order, we can avoid taking the rmap locks in move_ptes(). Essentially, this reintroduces the optimization that had been disabled in "mm anon rmap: remove anon_vma_moveto_tail". The difference is that we don't try to impose the rmap traversal order; instead we just rely on things being in the desired order in the common case and fall back to taking locks in the uncommon case. Also we skip the i_mmap_mutex in addition to the anon_vma lock: in both cases, the vmas are traversed in increasing vm_pgoff order with ties resolved in tree insertion order.

The ideal was that a counter be maintained for each pageblock but maintaining this information would incur a severe penalty due to a shared writable cache line. It has reached the point where the scanning costs are a serious problem, particularly on long-lived systems where a large process starts and allocates a large number of THPs at the same time. Instead of using a shared counter, this patch adds another bit to the pageblock flags called PG_migrate_skip. If a pageblock is scanned by either migrate or free scanner and 0 pages were isolated, the pageblock is marked to be skipped in the future. When scanning, this bit is checked before any scanning takes place and the block skipped if set. The main difficulty with a patch like this is "when to ignore the cached information?" If it's ignored too often, the scanning rates will still be excessive. If the information is too stale then allocations will fail that might have otherwise succeeded. In this patch o CMA always ignores the information o If the migrate and free scanner meet then the cached information will be discarded if it's at least 5 seconds since the last time the cache was discarded o If there are a large number of allocation failures, discard the cache. The time-based heuristic is very clumsy but there are few choices for a better event. Depending solely on multiple allocation failures still allows excessive scanning when THP allocations are failing in quick succession due to memory pressure. Waiting until memory pressure is relieved would cause compaction to continually fail instead of using reclaim/compaction to try allocate the page. The time-based mechanism is clumsy but a better option is not obvious.

Order > 0 compaction stops when enough free pages of the correct page order have been coalesced. When doing subsequent higher order allocations, it is possible for compaction to be invoked many times. However, the compaction code always starts out looking for things to compact at the start of the zone, and for free pages to compact things to at the end of the zone. This can cause quadratic behaviour, with isolate_freepages starting at the end of the zone each time, even though previous invocations of the compaction code already filled up all free memory on that end of the zone. This can cause isolate_freepages to take enormous amounts of CPU with certain workloads on larger memory systems. This patch caches where the migration and free scanner should start from on subsequent compaction invocations using the pageblock-skip information. When compaction starts it begins from the cached restart points and will update the cached restart points until a page is isolated or a pageblock is skipped that would have been scanned by synchronous compaction.

This information is not cleared by the page allocator based on activity due to the impact it would have to the page allocator fast paths. Hence there is a requirement that something clear the cache or pageblocks will be skipped forever. Currently the cache is cleared if there were a number of recent allocation failures and it has not been cleared within the last 5 seconds. Time-based decisions like this are terrible as they have no relationship to VM activity and is basically a big hammer. Unfortunately, accurate heuristics would add cost to some hot paths so this patch implements a rough heuristic. There are two cases where the cache is cleared. 1. If a !kswapd process completes a compaction cycle (migrate and free scanner meet), the zone is marked compact_blockskip_flush. When kswapd goes to sleep, it will clear the cache. This is expected to be the common case where the cache is cleared. It does not really matter if kswapd happens to be asleep or going to sleep when the flag is set as it will be woken on the next allocation request. 2. If there have been multiple failures recently and compaction just finished being deferred then a process will clear the cache and start a full scan. This situation happens if there are multiple high-order allocation requests under heavy memory pressure. The clearing of the PG_migrate_skip bits and other scans is inherently racy but the race is harmless. For allocations that can fail such as THP, they will simply fail.

To do this, zone_reclaim_mode is set if the distance between any two nodes on the system is greather than this distance. This, however, ends up causing the page allocator to reclaim from every zone regardless of its affinity. What we really want is to reclaim only from zones that are closer than RECLAIM_DISTANCE. This patch adds a nodemask to each node that represents the set of nodes that are within this distance. During the zone iteration, if the bit for a zone's node is set for the local node, then reclaim is attempted; otherwise, the zone is skipped.

This patch solves the problem by calling invalidate_page notification after releasing the lock (but before freeing the page itself), or by wrapping the page invalidation with calls to invalidate_range_begin and invalidate_range_end. To prevent accidental changes to the invalidate_range_end arguments after the call to invalidate_range_begin, the patch introduces a convention of saving the arguments in consistently named locals: unsigned long mmun_start; /* For mmu_notifiers */ unsigned long mmun_end; /* For mmu_notifiers */ ... mmun_start = ... mmun_end = ... mmu_notifier_invalidate_range_start(mm, mmun_start, mmun_end); ... mmu_notifier_invalidate_range_end(mm, mmun_start, mmun_end); The patch changes code to use this convention for all calls to mmu_notifier_invalidate_range_start/end, except those where the calls are close enough so that anyone who glances at the code can see the values aren't changing. This patchset is a preliminary step towards on-demand paging design to be added to the RDMA stack. Why do we want on-demand paging for Infiniband? Applications register memory with an RDMA adapter using system calls, and subsequently post IO operations that refer to the corresponding virtual addresses directly to HW. Until now, this was achieved by pinning the memory during the registration calls. The goal of on demand paging is to avoid pinning the pages of registered memory regions (MRs). This will allow users the same flexibility they get when swapping any other part of their processes address spaces. Instead of requiring the entire MR to fit in physical memory, we can allow the MR to be larger, and only fit the current working set in physical memory. Why should anyone care? What problems are users currently experiencing? This can make programming with RDMA much simpler. Today, developers that are working with more data than their RAM can hold need either to deregister and reregister memory regions throughout their process's life, or keep a single memory region and copy the data to it. On demand paging will allow these developers to register a single MR at the beginning of their process's life, and let the operating system manage which pages needs to be fetched at a given time. In the future, we might be able to provide a single memory access key for each process that would provide the entire process's address as one large memory region, and the developers wouldn't need to register memory regions at all. Is there any prospect that any other subsystems will utilise these infrastructural changes? If so, which and how, etc? As for other subsystems, I understand that XPMEM wanted to sleep in MMU notifiers, as Christoph Lameter wrote at http://lkml.indiana.edu/hypermail/linux/kernel/0802.1/0460.html and perhaps Andrea knows about other use cases. Scheduling in mmu notifications is required since we need to sync the hardware with the secondary page tables change. A TLB flush of an IO device is inherently slower than a CPU TLB flush, so our design works by sending the invalidation request to the device, and waiting for an interrupt before exiting the mmu notifier handler. Avi said: kvm may be a buyer. kvm::mmu_lock, which serializes guest page faults, also protects long operations such as destroying large ranges. It would be good to convert it into a spinlock, but as it is used inside mmu notifiers, this cannot be done. (there are alternatives, such as keeping the spinlock and using a generation counter to do the teardown in O(1), which is what the "may" is doing up there).

So user can notice memory block is changed. But in the 2nd case, the memory block's state is not changed and the notification is not also sent to userspcae even if calling remove_memory(). So user cannot notice memory block is changed. For adding the notification at memory hot remove, the patch just prepare as follows: 1st case uses offline_pages() for offlining memory. 2nd case uses remove_memory() for offlining memory and changing memory block's state and notifing the information. The patch does not implement notification to remove_memory().

But even if offlining memory, we cannot notice it. So the patch updates the memory block's state and sends notification to userspace. Additionally, the memory device may contain more than one memory block. If the memory block has been offlined, __offline_pages() will fail. So we should try to offline one memory block at a time. Thus remove_memory() also check each memory block's state. So there is no need to check the memory block's state before calling remove_memory().

This is evident if you try to mlock(), munlock(), and then mlock() a range again. Currently: #define MAP_SIZE (4 << 30) /* 4GB */ void *ptr = mmap(NULL, MAP_SIZE, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS, 0, 0); mlock(ptr, MAP_SIZE); $ grep -E "Unevictable|Inactive\(anon" /proc/meminfo Inactive(anon): 6304 kB Unevictable: 4213924 kB munlock(ptr, MAP_SIZE); Inactive(anon): 4186252 kB Unevictable: 19652 kB mlock(ptr, MAP_SIZE); Inactive(anon): 4198556 kB Unevictable: 21684 kB Notice that less than 2MB was added to the unevictable list; this is because these pages in the range are not transparent hugepages since the 4GB range was allocated with mmap() and has no specific alignment. If posix_memalign() were used instead, unevictable would not have grown at all on the second mlock(). The fix is to call mlock_vma_page() so that the mlock bit is set and the page is added to the unevictable list.
