| | * KVM: Allow cross page reads and writes from cached translations.Andrew Honig2013-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for kvm_gfn_to_hva_cache_init functions for reads and writes that will cross a page. If the range falls within the same memslot, then this will be a fast operation. If the range is split between two memslots, then the slower kvm_read_guest and kvm_write_guest are used. Tested: Test against kvm_clock unit tests. Signed-off-by: Andrew Honig <ahonig@google.com> Signed-off-by: Gleb Natapov <gleb@redhat.com>

As Linus pointed out, the graphics drivers are probably in the best position to make this judgement, so this basically reverts 547b52463 and f9a37be0f and adds a new helper function. Followup patches will add support to nouveau and radeon for probing this ROM source if they can't find a ROM from some other source.

This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

In some cases (bond/team) a single address list is synched down to multiple devices. At the time of unsync, we have a leak in these lower devices, because "synced" is treated as a boolean and the address will not be unsynced for anything after the first device/call. Treat "synced" as a count (same as refcount) and allow all unsync calls to work. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This means that internal loopbacks within a device that have powered devices on them won't be powered up. Fix this by treating any path that is currently in the process of being recursed as having a single input or output so that it is counted for the purposes of power decisions.

The UAPI variant looks like this: struct sigaction { unsigned int sa_flags; __sighandler_t sa_handler; sigset_t sa_mask; }; but the core kernel's variant looks like this: struct sigaction { #ifndef __ARCH_HAS_ODD_SIGACTION __sighandler_t sa_handler; unsigned long sa_flags; #else unsigned long sa_flags; __sighandler_t sa_handler; #endif #ifdef __ARCH_HAS_SA_RESTORER __sigrestore_t sa_restorer; #endif sigset_t sa_mask; }; The problem is that sa_flags has been changed from an unsigned int to an unsigned long. Fix this by making sa_flags unsigned int if __ARCH_HAS_ODD_SIGACTION is defined. Whilst we're at it, rename __ARCH_HAS_ODD_SIGACTION to __ARCH_HAS_IRIX_SIGACTION.

This patch moves this code into libfc and sets up a split in discovery (one time) initialization code and (re-configurable) settings that will come in the next patch.

From Johannes Berg. 6) In mac80211, if we don't actually associate, do not restart the STA timer, otherwise we can crash. From Ben Greear. 7) Missing dma_mapping_error() check in e1000, ixgb, and e1000e. From Christoph Paasch. 8) Fix sja1000 driver defines to not conflict with SH port, from Marc Kleine-Budde. 9) Don't call il4965_rs_use_green with a NULL station, from Colin Ian King. 10) Suspend/Resume in the FEC driver fail because the buffer descriptors are not initialized at all the moments in which they should. Fix from Frank Li. 11) cpsw and davinci_emac drivers both use the wrong interface to restart a stopped TX queue. Use netif_wake_queue not netif_start_queue, the latter is for initialization/bringup not active management of the queue. From Mugunthan V N. 12) Fix regression in rate calculations done by psched_ratecfg_precompute(), missing u64 type promotion. From Sergey Popovich. 13) Fix length overflow in tg3 VPD parsing, from Kees Cook. 14) AOE driver fails to allocate enough headroom, resulting in crashes. Fix from Eric Dumazet. 15) RX overflow happens too quickly in sky2 driver because pause packet thresholds are not programmed correctly. From Mirko Lindner. 16) Bonding driver manages arp_interval and miimon settings incorrectly, disabling one unintentionally disables both. Fix from Nikolay Aleksandrov. 17) smsc75xx drivers don't program the RX mac properly for jumbo frames. Fix from Steve Glendinning. 18) Fix off-by-one in Codel packet scheduler. From Vijay Subramanian. 19) Fix packet corruption in atl1c by disabling MSI support, from Hannes Frederic Sowa. 20) netdev_rx_handler_unregister() needs a synchronize_net() to fix crashes in bonding driver unload stress tests. From Eric Dumazet. 21) rxlen field of ks8851 RX packet descriptors not interpreted correctly (it is 12 bits not 16 bits, so needs to be masked after shifting the 32-bit value down 16 bits). Fix from Max Nekludov. 22) Fix missed RX/TX enable in sh_eth driver due to mishandling of link change indications. From Sergei Shtylyov. 23) Fix crashes during spurious ECI interrupts in sh_eth driver, also from Sergei Shtylyov. 24) dm9000 driver initialization is done wrong for revision B devices with DSP PHY, from Joseph CHANG. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (53 commits) DM9000B: driver initialization upgrade sh_eth: make 'link' field of 'struct sh_eth_private' *int* sh_eth: workaround for spurious ECI interrupt sh_eth: fix handling of no LINK signal ks8851: Fix interpretation of rxlen field. net: add a synchronize_net() in netdev_rx_handler_unregister() MAINTAINERS: Update netxen_nic maintainers list atl1e: drop pci-msi support because of packet corruption net: fq_codel: Fix off-by-one error net: calxedaxgmac: Wake-on-LAN fixes net: calxedaxgmac: fix rx ring handling when OOM net: core: Remove redundant call to 'nf_reset' in 'dev_forward_skb' smsc75xx: fix jumbo frame support net: fix the use of this_cpu_ptr bonding: fix disabling of arp_interval and miimon ipv6: don't accept node local multicast traffic from the wire sky2: Threshold for Pause Packet is set wrong sky2: Receive Overflows not counted aoe: reserve enough headroom on skbs line up comment for ndo_bridge_getlink ...

Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.

This will add a strings folder incl. language code like strings/409/manufacturer as suggested by Alan. - rebased ontop reworked functions.c which has usb_function_instance which is used prior after "mkdir acm.instance" and can be directly used for configuration via configfs. v3…v4 - moved functions from the root folde down to the gadget as suggested by Michał - configs have now their own configs folder as suggested by Michał. The folder is still name.bConfigurationValue where name becomes the sConfiguration. Is this usefull should we just stilc configs/bConfigurationValue/ ? - added configfs support to the ACM function. The port_num attribute is exported by f_acm. An argument has been added to the USB alloc function to distinguish between "old" (use facm_configure() to configure and configfs interface (expose a config_node). The port_num is currently a dumb counter. It will require some function re-work to make it work. scheduled for v5: - sym linking function into config. v2…v3 - replaced one ifndef by ifdef as suggested by Micahał - strstr()/strchr() function_make as suggested by Micahł - replace [iSerialNumber|iProduct|iManufacturer] with [sSerialNumber|sProduct|sManufacturer] as suggested by Alan - added creation of config descriptors v1…v2 - moved gadgets from configfs' root directory into /udcs/ within our "usb_gadget" folder. Requested by Andrzej & Michał - use a dot as a delimiter between function's name and its instance's name as suggested by Michał - renamed all config_item_type, configfs_group_operations, make_group, drop_item as suggested by suggested by Andrzej to remain consisten within this file and within other configfs users - Since configfs.c and functions.c are now part of the udc-core module, the module itself is now called udc. Also added a tiny ifdef around init code becuase udc-core is subsys init and this is too early for configfs in the built-in case. In the module case, we can only have one init function.

This may cause the frontend driver to behave incorrectly or crash. Since the ID field in the request is always in the same place, regardless of the request type we can get the correct ID and make a valid response (which will report BLKIF_RSP_EOPNOTSUPP). This bug affected 64-bit SLES 11 guests when using a 32-bit backend.

VM_POPULATE only has any effect when userspace plays racy games with vmas by trying to unmap and remap memory regions that mmap or mlock are operating on. Also, the only effect of VM_POPULATE when userspace plays such games is that it avoids populating new memory regions that get remapped into the address range that was being operated on by the original mmap or mlock calls. Let's remove VM_POPULATE as there isn't any strong argument to mandate a new vm_flag.
