* libata-core/sff: Fix multiple assumptions about DMAAlan Cox2007-06-09
| | | | | | | | | | | | | | | The ata IRQ ack functions are only used when debugging. Unfortunately almost every controller that calls them can cause crashes in some configurations as there are missing checks for bmdma presence. In addition ata_port_start insists of installing DMA buffers and pad buffers for controllers regardless. The SFF controllers actually need to make that decision dynamically at controller setup time and all need the same helper - so we add ata_sff_port_start. Future patches will switch the SFF drivers to use this. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* libata: fix probe time irq printoutsOlof Johansson2007-06-09
| | | | | | | | | | | | | | Most drivers don't seem to fill out the host->irq field, resulting in the wrong (no) irq being reported at probe time. For example, sil24 on my system: ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 ata2: SATA max UDMA/100 cmd 0xd000080090021000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 Since they're allocated and set up in ata_host_activate(), just save them away there.

| * ocfs2: Fix invalid assertion during write on 64k pagesMark Fasheh2007-06-06
| | | | | | | | | | | | | | | | | | | | | | | | The write path code intends to bug if a math error (or unhandled case) results in a write outside of the current cluster boundaries. The actual BUG_ON() statements however are incorrect, leading to a crash on kernels with 64k page size. Fix those by checking against the right variables. Also, move the assertions higher up within the functions so that they trip *before* the code starts to mark buffers. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IPv4 options are not very well aligned within the packet and the format of a CIPSO option is even worse. The result is that the CIPSO engine in the kernel does a few unaligned accesses when parsing and validating incoming packets with CIPSO options attached which generate error messages on certain alignment sensitive platforms. This patch fixes this by marking these unaligned accesses with the get_unaliagned() macro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current NetLabel code has some redundant APIs which allow both "struct socket" and "struct sock" types to be used; this may have made sense at some point but it is wasteful now. Remove the functions that operate on sockets and convert the callers. Not only does this make the code smaller and more consistent but it pushes the locking burden up to the caller which can be more intelligent about the locks. Also, perform the same conversion (socket to sock) on the SELinux/NetLabel glue code where it make sense.

Just like Simba bridges, some PCI bridges can lack the 'ranges' OBP property. So we handle this similarly to the existing Simba code: 1) In of_device register address resolving, we push the translation to the parent. 2) In PCI device scanning, we interrogate the PCI config space registers of the PCI bus device in order to resolve the resources, just like the generic Linux PCI probing code does.

Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.

| * | | USB: cxacru: create sysfs attributes in atm_start instead of bindSimon Arlott2007-06-08

Reading the MAC address from atm_dev before atm_dev exists would have been be possible too. Calling create_device_file in atm_start will avoid this problem, and the data is useless until the first status poll runs. However, it must be ready before a status poll does a printk on line status change otherwise userspace could react before the files exist. For completeness I've moved remove_device_file to atm_stop so it's not called in unbind when it's not needed. There's no point starting ADSL if atm_start could still fail either.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe to call with pointers into packed structures, since those are inlined functions and GCC may lose the "packed" attribute. So those references can become unaligned kernel accesses, which are evil on some hardware. This patch updates uses of those routines in the gadget stack. The references into packed structures can just use leXX_to_cpu(*x), which in most cases is more natural. Some other uses in RNDIS, mostly in debug code, were wrong in the first place; those use get_unaligned().

Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

Thus we encounter a section hole with empty section map pointer for SPARSEMEM and OOPs for show_mem. This issue has been seen in 2.6.21, current git and current mm. The patch below is for mainline and mm. It was boot tested for SPARSEMEM, current VMEMMAP of Andy's in mm ml and DISCONTIGMEM. A slightly different patch will be posted to stable for 2.6.21. Previous to commit f0a5a58aa812b31fd9f197c4ba48245942364eae memory_present was called for node_start_pfn to node_end_pfn. This would cover the hole(s) with reserved pages and valid sections. Most SPARSEMEM supported arches do a pfn_valid check in show_mem before computing the page structure address. This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo. Thanks to Arnaldo for testing.

* | | pi-futex: fix exit races and locking problemsAlexey Kuznetsov2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. New entries can be added to tsk->pi_state_list after task completed exit_pi_state_list(). The result is memory leakage and deadlocks. 2. handle_mm_fault() is called under spinlock. The result is obvious. 3. results in self-inflicted deadlock inside glibc. Sometimes futex_lock_pi returns -ESRCH, when it is not expected and glibc enters to for(;;) sleep() to simulate deadlock. This problem is quite obvious and I think the patch is right. Though it looks like each "if" in futex_lock_pi() got some stupid special case "else if". :-) 4. sometimes futex_lock_pi() returns -EDEADLK, when nobody has the lock. The reason is also obvious (see comment in the patch), but correct fix is far beyond my comprehension. I guess someone already saw this, the chunk: if (rt_mutex_trylock(&q.pi_state->pi_mutex)) ret = 0; is obviously from the same opera. But it does not work, because the rtmutex is really taken at this point: wake_futex_pi() of previous owner reassigned it to us. My fix works. But it looks very stupid. I would think about removal of shift of ownership in wake_futex_pi() and making all the work in context of process taking lock. From: Thomas Gleixner <tglx@linutronix.de> Fix 1) Avoid the tasklist lock variant of the exit race fix by adding an additional state transition to the exit code. This fixes also the issue, when a task with recursive segfaults is not able to release the futexes. Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH problem finally. Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup in the lock protected section by using the in_atomic userspace access functions. This removes also the ugly lock drop / unqueue inside of fixup_pi_state() Fix 4) Fix a stale lock in the error path of futex_wake_pi() Added some error checks for verification. The -EDEADLK problem is solved by the rtmutex fixups.

* | | rt-mutex: fix chain walk early wakeup bugThomas Gleixner2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alexey Kuznetsov found some problems in the pi-futex code. One of the root causes is: When a wakeup happens, we do not to stop the chain walk so we follow a not longer relevant locking chain. Drop out when this happens.

* | | rt-mutex: fix stale return valueThomas Gleixner2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alexey Kuznetsov found some problems in the pi-futex code. The major problem is a stale return value in rt_mutex_slowlock(): When the pi chain walk returns -EDEADLK, but the waiter was woken up during the phases where the locks were dropped, the rtmutex could be acquired, but due to the stale return value -EDEADLK returned to the caller. Reset the return value in the retry path.

* | | sata_promise: use TF interface for polling NODATA commandsTejun Heo2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sata_promise uses two different command modes - packet and TF. Packet mode is intelligent low-overhead mode while TF is the same old taskfile interface. As with other advanced interface (ahci/sil24), ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are issued using TF interface in polling mode, so pdc_interrupt() considers interrupts spurious if ATA_TFLAG_POLLING is set. This is broken for polling NODATA commands because command is issued using packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING. Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued using TF interface if ATA_TFLAG_POLLING is set. This patch fixes detection failure introduced by polling SETXFERMODE.
