commit 8e0e99ba upstream. It has come to my attention (thanks Martin) that 'discard_zeroes_data' is only a hint. Some devices in some cases don't do what it says on the label. The use of DISCARD in RAID5 depends on reads from discarded regions being predictably zero. If a write to a previously discarded region performs a read-modify-write cycle it assumes that the parity block was consistent with the data blocks. If all were zero, this would be the case. If some are and some aren't this would not be the case. This could lead to data corruption after a device failure when data needs to be reconstructed from the parity. As we cannot trust 'discard_zeroes_data', ignore it by default and so disallow DISCARD on all raid4/5/6 arrays. As many devices are trustworthy, and as there are benefits to using DISCARD, add a module parameter to over-ride this caution and cause DISCARD to work if discard_zeroes_data is set. If a site want to enable DISCARD on some arrays but not on others they should select DISCARD support at the filesystem level, and set the raid456 module parameter. raid456.devices_handle_discard_safely=Y As this is a data-safety issue, I believe this patch is suitable for -stable. DISCARD support for RAID456 was added in 3.7 Cc: Shaohua Li <shli@kernel.org> Cc: "Martin K.

commit d62dbf77 upstream. When building this driver as a module, we get a helpful warning about the return type: drivers/cpufreq/integrator-cpufreq.c:232:2: warning: initialization from incompatible pointer type .remove = __exit_p(integrator_cpufreq_remove), If the remove callback returns void, the caller gets an undefined value as it expects an integer to be returned. This fixes the problem by passing down the value from cpufreq_unregister_driver. Signed-off-by:

commit d3cb8bf6 upstream. A migration entry is marked as write if pte_write was true at the time the entry was created. The VMA protections are not double checked when migration entries are being removed as mprotect marks write-migration-entries as read. It means that potentially we take a spurious fault to mark PTEs write again but it's straight-forward. However, there is a race between write migrations being marked read and migrations finishing. This potentially allows a PTE to be write that should have been read. Close this race by double checking the VMA permissions using maybe_mkwrite when migration completes.

commit 6c72e350 upstream. Oleg noticed that a cleanup by Sylvain actually uncovered a bug; by calling perf_event_free_task() when failing sched_fork() we will not yet have done the memset() on ->perf_event_ctxp[] and will therefore try and 'free' the inherited contexts, which are still in use by the parent process. This is bad.. Suggested-by:

commit c03aa9f6 upstream. We did not implement any bound on number of indirect ICBs we follow when loading inode. Thus corrupted medium could cause kernel to go into an infinite loop, possibly causing a stack overflow. Fix the possible stack overflow by removing recursion from __udf_read_inode() and limit number of indirect ICBs we follow to avoid infinite loops. Signed-off-by:

commit ff20783f upstream. Clocks that don't have a pre-divider don't list any pre-divider in their frequency tables, but their tables are initialized using aggregate initializers. Use tagged initializers so we properly assign the m and n values for each frequency. Furthermore, the mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second element to pll2 instead of pll8, causing the clock driver to recalculate the wrong rate for any clocks using this array along with a rate that uses pll2. Plus the .num_parents field is 3 instead of 4 so you can't even switch the parent to pll3. Finally I noticed that the jpegd clock improperly indicates that the pre-divider width is only 2, when it's actually 4 bits wide.

commit 067bb174 upstream. In some cases, clocks can switch their parent with clk_set_rate, for example clk_mux can do this in some cases. Current implementation of clk_change_rate uses un-safe list iteration on the clock children, which will cause wrong clocks to be parsed in case any of the clock children change their parents during the change rate operation. Fixed by using the safe list iterator instead. The problem was detected due to some divide by zero errors generated by clock init on dra7-evm board, see discussion under http://article.gmane.org/gmane.linux.ports.arm.kernel/349180 for details.

commit b8cb6b4c upstream. If a devices is being recovered it is not InSync and is not Faulty. If a read error is experienced on that device, fix_read_error() will be called, but it ignores non-InSync devices. So it will neither fix the error nor fail the device. It is incorrect that fix_read_error() ignores non-InSync devices. It should only ignore Faulty devices. So fix it. This became a bug when we allowed reading from a device that was being recovered. It is suitable for any subsequent -stable kernel. Fixes: da8840a7Reported-by:

commit 34e97f17 upstream. Both normal IO and resync IO can be retried with reschedule_retry() and so be counted into ->nr_queued, but only normal IO gets counted in ->nr_pending. Before the recent improvement to RAID1 resync there could only possibly have been one or the other on the queue. When handling a read failure it could only be normal IO. So when handle_read_error() called freeze_array() the fact that freeze_array only compares ->nr_queued against ->nr_pending was safe. But now that these two types can interleave, we can have both normal and resync IO requests queued, so we need to count them both in nr_pending. This error can lead to freeze_array() hanging if there is a read error, so it is suitable for -stable. Fixes: 79ef3a8aReported-by:

commit c2fd4c94 upstream. raise_barrier() uses next_resync as part of its calculations, so it really should be updated first, instead of afterwards. next_resync is always used under resync_lock so update it under resync lock to, just before it is used. That is safest. This could cause normal IO and resync IO to interact badly so it suitable for -stable. Fixes: 79ef3a8aSigned-off-by:

commit 23554960 upstream. next_resync is (approximately) the location for the next resync request. However it does *not* reliably determine the earliest location at which resync might be happening. This is because resync requests can complete out of order, and we only limit the number of current requests, not the distance from the earliest pending request to the latest. mddev->curr_resync_completed is a reliable indicator of the earliest position at which resync could be happening. It is updated less frequently, but is actually reliable which is more important. So use it to determine if a write request is before the region being resynced and so safe from conflict. This error can allow resync IO to interfere with normal IO which could lead to data corruption. Hence: stable. Fixes: 79ef3a8aSigned-off-by:

commit 2f73d3c5 upstream. The resync/recovery process for raid1 was recently changed so that writes could happen in parallel with resync providing they were in different regions of the device. There is a problem though: While a write request will always wait for conflicting resync to complete, a resync request will *not* always wait for conflicting writes to complete. Two changes are needed to fix this: 1/ raise_barrier (which waits until it is safe to do resync) must wait until current_window_requests is zero 2/ wait_battier (which waits at the start of a new write request) must update current_window_requests if the request could possible conflict with a concurrent resync. As concurrent writes and resync can lead to data loss, this patch is suitable for -stable. Fixes: 79ef3a8a Cc: majianpeng <majianpeng@gmail.com> Signed-off-by:

commit c6d119cf upstream. commit 79ef3a8a made it possible for reads to happen concurrently with resync. This means that we need to be more careful where read_balancing is allowed during resync - we can no longer be sure that any resync that has already started will definitely finish. So keep read_balancing to before recovery_cp, which is conservative but safe. This bug makes it possible to read from a device that doesn't have up-to-date data, so it can cause data corruption. So it is suitable for any kernel since 3.11. Fixes: 79ef3a8aSigned-off-by:

commit 669cc7ba upstream. If there are outstanding writes when close_sync is called, the change to ->start_next_window might cause them to decrement the wrong counter when they complete.

commit bd8c78e7 upstream. In testmode and vendor command reply/event SKBs we use the skb cb data to store nl80211 parameters between allocation and sending. This causes the code for CONFIG_NETLINK_MMAP to get confused, because it takes ownership of the skb cb data when the SKB is handed off to netlink, and it doesn't explicitly clear it. Clear the skb cb explicitly when we're done and before it gets passed to netlink to avoid this issue. Reported-by:

commit f2d5a944 upstream. On 32-bit architectures, the legacy buffer_head functions are not always handling the sector number with the proper 64-bit types, and will thus fail on 4TB+ disks. Any code that uses __getblk() (and thus bread(), breadahead(), sb_bread(), sb_breadahead(), sb_getblk()), and calls it using a 64-bit block on a 32-bit arch (where "long" is 32-bit) causes an inifinite loop in __getblk_slow() with an infinite stream of errors logged to dmesg like this: __find_get_block_slow() failed. block=6740375944, b_blocknr=2445408648 b_state=0x00000020, b_size=512 device sda1 blocksize: 512 Note how in hex block is 0x191C1F988 and b_blocknr is 0x91C1F988 i.e. the top 32-bits are missing (in this case the 0x1 at the top). This is because grow_dev_page() is broken and has a 32-bit overflow due to shifting the page index value (a pgoff_t - which is just 32 bits on 32-bit architectures) left-shifted as the block number. But the top bits to get lost as the pgoff_t is not type cast to sector_t / 64-bit before the shift. This patch fixes this issue by type casting "index" to sector_t before doing the left shift. Note this is not a theoretical bug but has been seen in the field on a 4TiB hard drive with logical sector size 512 bytes. This patch has been verified to fix the infinite loop problem on 3.17-rc5 kernel using a 4TB disk image mounted using "-o loop". Without this patch doing a "find /nt" where /nt is an NTFS volume causes the inifinite loop 100% reproducibly whilst with the patch it works fine as expected. Signed-off-by:
