2014-06-30mm/memory-failure.c: support use of a dedicated thread to handle ↵Naoya Horiguchi
SIGBUS(BUS_MCEERR_AO) commit 3ba08129e38437561df44c36b7ea9081185d5333 upstream. Currently memory error handler handles action optional errors in the deferred manner by default. And if a recovery aware application wants to handle it immediately, it can do it by setting PF_MCE_EARLY flag. However, such signal can be sent only to the main thread, so it's problematic if the application wants to have a dedicated thread to handler such signals. So this patch adds dedicated thread support to memory error handler. We have PF_MCE_EARLY flags for each thread separately, so with this patch AO signal is sent to the thread with PF_MCE_EARLY flag set, not the main thread. If you want to implement a dedicated thread, you call prctl() to set PF_MCE_EARLY on the thread. Memory error handler collects processes to be killed, so this patch lets it check PF_MCE_EARLY flag on each thread in the collecting routines. No behavioral change for all non-early kill cases. Tony said: : The old behavior was crazy - someone with a multithreaded process might : well expect that if they call prctl(PF_MCE_EARLY) in just one thread, then : that thread would see the SIGBUS with si_code = BUS_MCEERR_A0 - even if : that thread wasn't the main thread for the process.

2014-06-26ima: audit log files opened with O_DIRECT flagMimi Zohar
commit f9b2a735bdddf836214b5dca74f6ca7712e5a08c upstream. Files are measured or appraised based on the IMA policy. When a file, in policy, is opened with the O_DIRECT flag, a deadlock occurs. The first attempt at resolving this lockdep temporarily removed the O_DIRECT flag and restored it, after calculating the hash. The second attempt introduced the O_DIRECT_HAVELOCK flag. Based on this flag, do_blockdev_direct_IO() would skip taking the i_mutex a second time. The third attempt, by Dmitry Kasatkin, resolves the i_mutex locking issue, by re-introducing the IMA mutex, but uncovered another problem. Reading a file with O_DIRECT flag set, writes directly to userspace pages. A second patch allocates a user-space like memory. This works for all IMA hooks, except ima_file_free(), which is called on __fput() to recalculate the file hash. Until this last issue is addressed, do not 'collect' the measurement for measuring, appraising, or auditing files opened with the O_DIRECT flag set. Based on policy, permit or deny file access. This patch defines a new IMA policy rule option named 'permit_directio'. Policy rules could be defined, based on LSM or other criteria, to permit specific applications to open files with the O_DIRECT flag set.

2014-06-11dm thin: add 'no_space_timeout' dm-thin-pool module paramMike Snitzer
commit 80c578930ce77ba8bcfb226a184b482020bdda7b upstream. Commit 85ad643b ("dm thin: add timeout to stop out-of-data-space mode holding IO forever") introduced a fixed 60 second timeout. Users may want to either disable or modify this timeout. Allow the out-of-data-space timeout to be configured using the 'no_space_timeout' dm-thin-pool module param. Setting it to 0 will disable the timeout, resulting in IO being queued until more data space is added to the thin-pool.

2014-06-11firewire: revert to 4 GB RDMA, fix protocols using Memory SpaceStefan Richter
commit 2fe2023adf695d08af5b598b2be3b288a95d563c upstream. Undo a feature introduced in v3.14 by commit fcd46b34425d "firewire: Enable remote DMA above 4 GB". That change raised the minimum address at which protocol drivers and user programs can register for request reception from 0x0001'0000'0000 to 0x8000'0000'0000. It turned out that at least one vendor-specific protocol exists which uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921 For the time being, revert most of commit fcd46b34425d so that affected protocols work like with kernel v3.13 and before. Just keep the valid documentation parts from the regressing commit, and the ability to identify controllers which could be programmed to accept >32 bit physical DMA addresses. The rest of fcd46b34425d should probably be brought back as an optional instead of default feature.

2014-06-07Input: elantech - fix touchpad initialization on Gigabyte U2442Hans de Goede
commit 36189cc3cd57ab0f1cd75241f93fe01de928ac06 upstream. The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept 0x0b as initialization value for r10, this stand-alone version of the driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2 Uses 0x03 which does work, so this means not setting bit 3 of r10 which sets: "Enable Real H/W Resolution In Absolute mode" Which will result in half the x and y resolution we get with that bit set, so simply not setting it everywhere is not a solution. We've been unable to find a way to identify touchpads where setting the bit will fail, so this patch uses a dmi based blacklist for this. https://bugzilla.kernel.org/show_bug.cgi?id=61151 Reported-by: Philipp Wolfer <ph.wolfer@gmail.com> Tested-by: Philipp Wolfer <ph.wolfer@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-06-07ARM: common: edma: Fix xbar mappingThomas Gleixner
commit cf7eb979116c2568e8bc3b6a7269c7a359864ace upstream. This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.

2014-05-06hung_task: check the value of "sysctl_hung_task_timeout_sec"Liu Hua
commit 80df28476505ed4e6701c3448c63c9229a50c655 upstream. As sysctl_hung_task_timeout_sec is unsigned long, when this value is larger then LONG_MAX/HZ, the function schedule_timeout_interruptible in watchdog will return immediately without sleep and with print : schedule_timeout: wrong timeout value ffffffffffffff83 and then the funtion watchdog will call schedule_timeout_interruptible again and again. The screen will be filled with "schedule_timeout: wrong timeout value ffffffffffffff83" This patch does some check and correction in sysctl, to let the function schedule_timeout_interruptible allways get the valid parameter.

Pull networking fixes from David Miller: "I know this is a bit more than you want to see, and I've told the wireless folks under no uncertain terms that they must severely scale back the extent of the fixes they are submitting this late in the game. Anyways: 1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which is the correct implementation, like it should. Instead it does something like a NAPI poll operation. This leads to crashes. From Neil Horman and Arnd Bergmann. 2) Segmentation of SKBs requires proper socket orphaning of the fragments, otherwise we might access stale state released by the release callbacks. This is a 5 patch fix, but the initial patches are giving variables and such significantly clearer names such that the actual fix itself at the end looks trivial. From Michael S. Tsirkin. 3) TCP control block release can deadlock if invoked from a timer on an already "owned" socket. Fix from Eric Dumazet. 4) In the bridge multicast code, we must validate that the destination address of general queries is the link local all-nodes multicast address. From Linus Lüssing. 5) The x86 BPF JIT support for negative offsets puts the parameter for the helper function call in the wrong register. Fix from Alexei Starovoitov. 6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the r8169 driver is incorrect. Fix from Hayes Wang. 7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see if a packet is a GSO frame, but that's not the correct test. It should use skb_is_gso(skb) instead. Fix from Wei Liu. 8) Negative msg->msg_namelen values should generate an error, from Matthew Leach. 9) at86rf230 can deadlock because it takes the same lock from it's ISR and it's hard_start_xmit method, without disabling interrupts in the latter. Fix from Alexander Aring. 10) The FEC driver's restart doesn't perform operations in the correct order, so promiscuous settings can get lost. Fix from Stefan Wahren. 11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann. 12) Reference count and memory leak fixes in TIPC from Ying Xue and Erik Hugne. 13) Forced eviction in inet_frag_evictor() must strictly make sure all frags are deleted, otherwise module unload (f.e. 6lowpan) can crash. Fix from Florian Westphal. 14) Remove assumptions in AF_UNIX's use of csum_partial() (which it uses as a hash function), which breaks on PowerPC. From Anton Blanchard. The main gist of the issue is that csum_partial() is defined only as a value that, once folded (f.e. via csum_fold()) produces a correct 16-bit checksum. It is legitimate, therefore, for csum_partial() to produce two different 32-bit values over the same data if their respective alignments are different. 15) Fix endiannes bug in MAC address handling of ibmveth driver, also from Anton Blanchard. 16) Error checks for ipv6 exthdrs offload registration are reversed, from Anton Nayshtut. 17) Externally triggered ipv6 addrconf routes should count against the garbage collection threshold. Fix from Sabrina Dubroca. 18) The PCI shutdown handler added to the bnx2 driver can wedge the chip if it was not brought up earlier already, which in particular causes the firmware to shut down the PHY. Fix from Michael Chan. 19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as currently coded it can and does trigger in legitimate situations. From Eric Dumazet. 20) BNA driver fails to build on ARM because of a too large udelay() call, fix from Ben Hutchings. 21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix from Eric Dumazet. 22) The vlan passthrough ops added in the previous release causes a regression in source MAC address setting of outgoing headers in some circumstances.

2014-03-05dm thin: ensure user takes action to validate data and metadata consistencyMike Snitzer
If a thin metadata operation fails the current transaction will abort, whereby causing potential for IO layers up the stack (e.g. filesystems) to have data loss. As such, set THIN_METADATA_NEEDS_CHECK_FLAG in the thin metadata's superblock which: 1) requires the user verify the thin metadata is consistent (e.g. use thin_check, etc) 2) suggests the user verify the thin data is consistent (e.g. use fsck) The only way to clear the superblock's THIN_METADATA_NEEDS_CHECK_FLAG is to run thin_repair. On metadata operation failure: abort current metadata transaction, set pool in read-only mode, and now set the needs_check flag. As part of this change, constraints are introduced or relaxed: * don't allow a pool to transition to write mode if needs_check is set * don't allow data or metadata space to be resized if needs_check is set * if a thin pool's metadata space is exhausted: the kernel will now force the user to take the pool offline for repair before the kernel will allow the metadata space to be extended. Also, update Documentation to include information about when the thin provisioning target commits metadata, how it handles metadata failures and running out of space.

2014-03-03can: remove CAN FD compatibility for CAN 2.0 socketsOliver Hartkopp
In commit e2d265d3b587 (canfd: add support for CAN FD in CAN_RAW sockets) CAN FD frames with a payload length up to 8 byte are passed to legacy sockets where the CAN FD support was not enabled by the application. After some discussions with developers at a fair this well meant feature leads to confusion as no clean switch for CAN / CAN FD is provided to the application programmer. Additionally a compatibility like this for legacy CAN_RAW sockets requires some compatibility handling for the sending, e.g. make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?). This will become a mess when people start to develop applications with real CAN FD hardware. This patch reverts the bad compatibility code together with the documentation describing the removed feature.
