2014-04-03netfilter: nf_conntrack_dccp: fix skb_header_pointer API usagesDaniel Borkmann
commit b22f5126a24b3b2f15448c3f2a254fc10cbc2b92 upstream. Some occurences in the netfilter tree use skb_header_pointer() in the following way ... struct dccp_hdr _dh, *dh; ... skb_header_pointer(skb, dataoff, sizeof(_dh), &dh); ... where dh itself is a pointer that is being passed as the copy buffer. Instead, we need to use &_dh as the forth argument so that we're copying the data into an actual buffer that sits on the stack. Currently, we probably could overwrite memory on the stack (e.g. with a possibly mal-formed DCCP packet), but unintentionally, as we only want the buffer to be placed into _dh variable.

2014-04-03x86: fix boot on uniprocessor systemsArtem Fetishev
commit 825600c0f20e595daaa7a6dd8970f84fa2a2ee57 upstream. On x86 uniprocessor systems topology_physical_package_id() returns -1 which causes rapl_cpu_prepare() to leave rapl_pmu variable uninitialized which leads to GPF in rapl_pmu_init(). See arch/x86/kernel/cpu/perf_event_intel_rapl.c. It turns out that physical_package_id and core_id can actually be retreived for uniprocessor systems too. Enabling them also fixes rapl_pmu code.

2014-04-03Input: synaptics - add manual min/max quirkBenjamin Tissoires
commit 421e08c41fda1f0c2ff6af81a67b491389b653a5 upstream. The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad. However, these new Synaptics devices report bad axis ranges. Under Windows, it is not a problem because the Windows driver uses RMI4 over SMBus to talk to the device. Under Linux, we are using the PS/2 fallback interface and it occurs the reported ranges are wrong. Of course, it would be too easy to have only one range for the whole series, each touchpad seems to be calibrated in a different way. We can not use SMBus to get the actual range because I suspect the firmware will switch into the SMBus mode and stop talking through PS/2 (this is the case for hybrid HID over I2C / PS/2 Synaptics touchpads). So as a temporary solution (until RMI4 land into upstream), start a new list of quirks with the min/max manually set.

2014-03-30ipc/msg: fix race around refcountKonstantin Khlebnikov
[fixed differently in 6062a8dc0517bce23e3c2f7d2fea5e22411269a3 upstream.] In older kernels (before v3.10) ipc_rcu_hdr->refcount was non-atomic int. There was possuble double-free bug: do_msgsnd() calls ipc_rcu_putref() under msq->q_perm->lock and RCU, while freequeue() calls it while it holds only 'rw_mutex', so there is no sinchronization between them. Two function decrements '2' non-atomically, they both can get '0' as result. do_msgsnd() freequeue() msq = msg_lock_check(ns, msqid); ... ipc_rcu_getref(msq); msg_unlock(msq); schedule(); (caller locks spinlock) expunge_all(msq, -EIDRM); ss_wakeup(&msq->q_senders, 1); msg_rmid(ns, msq); msg_unlock(msq); ipc_lock_by_ptr(&msq->q_perm); ipc_rcu_putref(msq); ipc_rcu_putref(msq); < both may get get --(...)->refcount == 0 > This patch locks ipc_lock and RCU around ipc_rcu_putref in freequeue. ( RCU protects memory for spin_unlock() ) Similar bugs might be in other users of ipc_rcu_putref(). In the mainline this has been fixed in v3.10 indirectly in commmit 6062a8dc0517bce23e3c2f7d2fea5e22411269a3 ("ipc,sem: fine grained locking for semtimedop") by Rik van Riel. That commit optimized locking and converted refcount into atomic. I'm not sure that anybody should care about this bug: it's very-very unlikely and no longer exists in actual mainline. I've found this just by looking into the code, probably this never happens in real life. Signed-off-by: Konstantin Khlebnikov <k.khlebnikov@samsung.com>

commit c15bdfd5b9831e4cab8cfc118243956e267dd30e upstream. The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.

2014-03-30i7300_edac: Fix device reference countJean Delvare
commit 75135da0d68419ef8a925f4c1d5f63d8046e314d upstream. pci_get_device() decrements the reference count of "from" (last argument) so when we break off the loop successfully we have only one device reference - and we don't know which device we have. If we want a reference to each device, we must take them explicitly and let the pci_get_device() walk complete to avoid duplicate references. This is serious, as over-putting device references will cause the device to eventually disappear. Without this fix, the kernel crashes after a few insmod/rmmod cycles.

2014-03-30libceph: resend all writes after the osdmap loses the full flagJosh Durgin
commit 9a1ea2dbff11547a8e664f143c1ffefc586a577a upstream. With the current full handling, there is a race between osds and clients getting the first map marked full. If the osd wins, it will return -ENOSPC to any writes, but the client may already have writes in flight. This results in the client getting the error and propagating it up the stack. For rbd, the block layer turns this into EIO, which can cause corruption in filesystems above it. To avoid this race, osds are being changed to drop writes that came from clients with an osdmap older than the last osdmap marked full. In order for this to work, clients must resend all writes after they encounter a full -> not full transition in the osdmap. osds will wait for an updated map instead of processing a request from a client with a newer map, so resent writes will not be dropped by the osd unless there is another not full -> full transition. This approach requires both osds and clients to be fixed to avoid the race. Old clients talking to osds with this fix may hang instead of returning EIO and potentially corrupting an fs. New clients talking to old osds have the same behavior as before if they encounter this race.

2014-03-23jiffies: Avoid undefined behavior from signed overflowPaul E. McKenney
commit 5a581b367b5df0531265311fc681c2abd377e5e6 upstream. According to the C standard 3.4.3p3, overflow of a signed integer results in undefined behavior. This commit therefore changes the definitions of time_after(), time_after_eq(), time_after64(), and time_after_eq64() to avoid this undefined behavior. The trick is that the subtraction is done using unsigned arithmetic, which according to 6.2.5p9 cannot overflow because it is defined as modulo arithmetic. This has the added (though admittedly quite small) benefit of shortening four lines of code by four characters each. Note that the C standard considers the cast from unsigned to signed to be implementation-defined, see 6.3.1.3p3. However, on a two's-complement system, an implementation that defines anything other than a reinterpretation of the bits is free to come to me, and I will be happy to act as a witness for its being committed to an insane asylum. (Although I have nothing against saturating arithmetic or signals in some cases, these things really should not be the default when compiling an operating-system kernel.) Signed-off-by: Paul E.

2014-03-23Btrfs: fix data corruption when reading/updating compressed extentsFilipe David Borba Manana
commit a2aa75e18a21b21952dc6daa9bac7c9f4426f81f upstream. When using a mix of compressed file extents and prealloc extents, it is possible to fill a page of a file with random, garbage data from some unrelated previous use of the page, instead of a sequence of zeroes. A simple sequence of steps to get into such case, taken from the test case I made for xfstests, is: _scratch_mkfs _scratch_mount "-o compress-force=lzo" $XFS_IO_PROG -f -c "pwrite -S 0x06 -b 18670 266978 18670" $SCRATCH_MNT/foobar $XFS_IO_PROG -c "falloc 26450 665194" $SCRATCH_MNT/foobar $XFS_IO_PROG -c "truncate 542872" $SCRATCH_MNT/foobar $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foobar This results in the following file items in the fs tree: item 4 key (257 INODE_ITEM 0) itemoff 15879 itemsize 160 inode generation 6 transid 6 size 542872 block group 0 mode 100600 item 5 key (257 INODE_REF 256) itemoff 15863 itemsize 16 inode ref index 2 namelen 6 name: foobar item 6 key (257 EXTENT_DATA 0) itemoff 15810 itemsize 53 extent data disk byte 0 nr 0 gen 6 extent data offset 0 nr 24576 ram 266240 extent compression 0 item 7 key (257 EXTENT_DATA 24576) itemoff 15757 itemsize 53 prealloc data disk byte 12849152 nr 241664 gen 6 prealloc data offset 0 nr 241664 item 8 key (257 EXTENT_DATA 266240) itemoff 15704 itemsize 53 extent data disk byte 12845056 nr 4096 gen 6 extent data offset 0 nr 20480 ram 20480 extent compression 2 item 9 key (257 EXTENT_DATA 286720) itemoff 15651 itemsize 53 prealloc data disk byte 13090816 nr 405504 gen 6 prealloc data offset 0 nr 258048 The on disk extent at offset 266240 (which corresponds to 1 single disk block), contains 5 compressed chunks of file data. Each of the first 4 compress 4096 bytes of file data, while the last one only compresses 3024 bytes of file data. Therefore a read into the file region [285648 ; 286720[ (length = 4096 - 3024 = 1072 bytes) should always return zeroes (our next extent is a prealloc one). The solution here is the compression code path to zero the remaining (untouched) bytes of the last page it uncompressed data into, as the information about how much space the file data consumes in the last page is not known in the upper layer fs/btrfs/extent_io.c:__do_readpage(). In __do_readpage we were correctly zeroing the remainder of the page but only if it corresponds to the last page of the inode and if the inode's size is not a multiple of the page size. This would cause not only returning random data on reads, but also permanently storing random data when updating parts of the region that should be zeroed. For the example above, it means updating a single byte in the region [285648 ; 286720[ would store that byte correctly but also store random data on disk. A test case for xfstests follows soon.

2014-03-23SCSI: isci: correct erroneous for_each_isci_host macroLukasz Dorau
commit c59053a23d586675c25d789a7494adfdc02fba57 upstream. In the first place, the loop 'for' in the macro 'for_each_isci_host' (drivers/scsi/isci/host.h:314) is incorrect, because it accesses the 3rd element of 2 element array. After the 2nd iteration it executes the instruction: ihost = to_pci_info(pdev)->hosts[2] (while the size of the 'hosts' array equals 2) and reads an out of range element. In the second place, this loop is incorrectly optimized by GCC v4.8 (see http://marc.info/?l=linux-kernel&m=138998871911336&w=2).

2014-03-23SCSI: isci: fix reset timeout handlingDan Williams
commit ddfadd7736b677de2d4ca2cd5b4b655368c85a7a upstream. Remove an erroneous BUG_ON() in the case of a hard reset timeout. The reset timeout handler puts the port into the "awaiting link-up" state. The timeout causes the device to be disconnected and we need to be in the awaiting link-up state to re-connect the port. The BUG_ON() made the incorrect assumption that resets never timeout and we always complete the reset in the "resetting" state. Testing this patch also uncovered that libata continues to attempt to reset the port long after the driver has torn down the context. Once the driver has committed to abandoning the link it must indicate to libata that recovery ends by returning -ENODEV from ->lldd_I_T_nexus_reset().

Since commit d25f06ea466e "vmxnet3: fix netpoll race condition", the vmxnet3 driver fails to build when CONFIG_PCI_MSI is disabled, because it unconditionally references the vmxnet3_msix_rx() function.

2014-03-23vmxnet3: fix netpoll race conditionNeil Horman
commit d25f06ea466ea521b563b76661180b4e44714ae6 upstream. vmxnet3's netpoll driver is incorrectly coded. It directly calls vmxnet3_do_poll, which is the driver internal napi poll routine. As the netpoll controller method doesn't block real napi polls in any way, there is a potential for race conditions in which the netpoll controller method and the napi poll method run concurrently. The result is data corruption causing panics such as this one recently observed: PID: 1371 TASK: ffff88023762caa0 CPU: 1 COMMAND: "rs:main Q:Reg" #0 [ffff88023abd5780] machine_kexec at ffffffff81038f3b #1 [ffff88023abd57e0] crash_kexec at ffffffff810c5d92 #2 [ffff88023abd58b0] oops_end at ffffffff8152b570 #3 [ffff88023abd58e0] die at ffffffff81010e0b #4 [ffff88023abd5910] do_trap at ffffffff8152add4 #5 [ffff88023abd5970] do_invalid_op at ffffffff8100cf95 #6 [ffff88023abd5a10] invalid_op at ffffffff8100bf9b [exception RIP: vmxnet3_rq_rx_complete+1968] RIP: ffffffffa00f1e80 RSP: ffff88023abd5ac8 RFLAGS: 00010086 RAX: 0000000000000000 RBX: ffff88023b5dcee0 RCX: 00000000000000c0 RDX: 0000000000000000 RSI: 00000000000005f2 RDI: ffff88023b5dcee0 RBP: ffff88023abd5b48 R8: 0000000000000000 R9: ffff88023a3b6048 R10: 0000000000000000 R11: 0000000000000002 R12: ffff8802398d4cd8 R13: ffff88023af35140 R14: ffff88023b60c890 R15: 0000000000000000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 #7 [ffff88023abd5b50] vmxnet3_do_poll at ffffffffa00f204a [vmxnet3] #8 [ffff88023abd5b80] vmxnet3_netpoll at ffffffffa00f209c [vmxnet3] #9 [ffff88023abd5ba0] netpoll_poll_dev at ffffffff81472bb7 The fix is to do as other drivers do, and have the poll controller call the top half interrupt handler, which schedules a napi poll properly to recieve frames Tested by myself, successfully.

commit 596f3142d2b7be307a1652d59e7b93adab918437 upstream. We always disable cr8 intercept in its handler, but only re-enable it if handling KVM_REQ_EVENT, so there can be a window where we do not intercept cr8 writes, which allows an interrupt to disrupt a higher priority task. Fix this by disabling intercepts in the same function that re-enables them when needed. This fixes BSOD in Windows 2008.

commit 70335abb2689c8cd5df91bf2d95a65649addf50b upstream. The expected logic of proc_map_files_get_link() is either to return 0 and initialize 'path' or return an error and leave 'path' uninitialized. By the time dname_to_vma_addr() returns 0 the corresponding vma may have already be gone. In this case the path is not initialized but the return value is still 0. This results in 'general protection fault' inside d_path().

commit 70044d71d31d6973665ced5be04ef39ac1c09a48 upstream. PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. firewire core-device and sbp2 have been been multiplexing work items with multiple work functions. Introduce fw_device_workfn() and sbp2_lu_workfn() which invoke fw_device->workfn and sbp2_logical_unit->workfn respectively and always use the two functions as the work functions and update the users to set the ->workfn fields instead of overriding work functions using PREPARE_DELAYED_WORK(). This fixes a variety of possible regressions since a2c1c57be8d9 "workqueue: consider work function when searching for busy work items" due to which fw_workqueue lost its required non-reentrancy property.

commit 45ab2813d40d88fc575e753c38478de242d03f88 upstream. If a module fails to add its tracepoints due to module tainting, do not create the module event infrastructure in the debugfs directory. As the events will not work and worse yet, they will silently fail, making the user wonder why the events they enable do not display anything. Having a warning on module load and the events not visible to the users will make the cause of the problem much clearer.

commit c685689fd24d310343ac33942e9a54a974ae9c43 upstream. We hit one rare case below: T1 calling disable_irq(), but hanging at synchronize_irq() always; The corresponding irq thread is in sleeping state; And all CPUs are in idle state; After analysis, we found there is one possible scenerio which causes T1 is waiting there forever: CPU0 CPU1 synchronize_irq() wait_event() spin_lock() atomic_dec_and_test(&threads_active) insert the __wait into queue spin_unlock() if(waitqueue_active) atomic_read(&threads_active) wake_up() Here after inserted the __wait into queue on CPU0, and before test if queue is empty on CPU1, there is no barrier, it maybe cause it is not visible for CPU1 immediately, although CPU0 has updated the queue list. It is similar for CPU0 atomic_read() threads_active also. So we'd need one smp_mb() before waitqueue_active.that, but removing the waitqueue_active() check solves it as wel l and it makes things simple and clear.

2014-03-23mwifiex: copy AP's HT capability info correctlyAmitkumar Karwar
commit c99b1861c232e1f641f13b8645e0febb3712cc71 upstream. While preparing association request, intersection of device's HT capability information and corresponding fields advertised by AP is used. This patch fixes an error while copying this field from AP's beacon. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2014-03-23ath9k: Fix ETSI compliance for AR9462 2.0Sujith Manoharan
commit b3050248c167871ca52cfdb2ce78aa2460249346 upstream. The minimum CCA power threshold values have to be adjusted for existing cards to be in compliance with new regulations. Newer cards will make use of the values obtained from EEPROM, support for this was added earlier. To make sure that cards that are already in use and don't have proper values in EEPROM, do not violate regulations, use the initvals instead.
