commit 24607f11 upstream. Commit 651e22f2 "ring-buffer: Always reset iterator to reader page" fixed one bug but in the process caused another one. The reset is to update the header page, but that fix also changed the way the cached reads were updated. The cache reads are used to test if an iterator needs to be updated or not. A ring buffer iterator, when created, disables writes to the ring buffer but does not stop other readers or consuming reads from happening. Although all readers are synchronized via a lock, they are only synchronized when in the ring buffer functions. Those functions may be called by any number of readers. The iterator continues down when its not interrupted by a consuming reader. If a consuming read occurs, the iterator starts from the beginning of the buffer. The way the iterator sees that a consuming read has happened since its last read is by checking the reader "cache". The cache holds the last counts of the read and the reader page itself. Commit 651e22f2 changed what was saved by the cache_read when the rb_iter_reset() occurred, making the iterator never match the cache. Then if the iterator calls rb_iter_reset(), it will go into an infinite loop by checking if the cache doesn't match, doing the reset and retrying, just to see that the cache still doesn't match! Which should never happen as the reset is suppose to set the cache to the current value and there's locks that keep a consuming reader from having access to the data.

commit 62b4d204 upstream. commit 03b8c7b6 ("futex: Allow architectures to skip futex_atomic_cmpxchg_inatomic() test") added the HAVE_FUTEX_CMPXCHG symbol right below FUTEX. This placed it right in the middle of the options for the EXPERT menu. However, HAVE_FUTEX_CMPXCHG does not depend on EXPERT or FUTEX, so Kconfig stops placing items in the EXPERT menu, and displays the remaining several EXPERT items (starting with EPOLL) directly in the General Setup menu. Since both users of HAVE_FUTEX_CMPXCHG only select it "if FUTEX", make HAVE_FUTEX_CMPXCHG itself depend on FUTEX. With this change, the subsequent items display as part of the EXPERT menu again; the EMBEDDED menu now appears as the next top-level item in the General Setup menu, which makes General Setup much shorter and more usable.

commit 19e81573 upstream. Changeset eb85d94b introduced a problem where if a cifs open fails during query info of a file we will still try to close the file (happens with certain types of reparse points) even though the file handle is not valid. In addition for SMB2/SMB3 we were not mapping the return code returned by Windows when trying to open a file (like a Windows NFS symlink) which is a reparse point. Signed-off-by:

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 77076c7a upstream. Some of the Thinkpads' firmware will issue a backlight change request through i915 operation region unconditionally on AC plug/unplug, the backlight level used is arbitrary and thus should be ignored. This is handled by commit 0b9f7d93 (ACPI / i915: ignore firmware requests for backlight change). Then there is a Dell laptop whose vendor backlight interface also makes use of operation region to change backlight level and with the above commit, that interface no long works. The condition used to ignore the backlight change request from firmware is thus changed to: if the vendor backlight interface is not in use and the ACPI backlight interface is broken, we ignore the requests; oterwise, we keep processing them.

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 2f7dd7a4 upstream. The cgroup iterators yield css objects that have not yet gone through css_online(), but they are not complete memcgs at this point and so the memcg iterators should not return them. Commit d8ad3055 ("mm/memcg: iteration skip memcgs not yet fully initialized") set out to implement exactly this, but it uses CSS_ONLINE, a cgroup-internal flag that does not meet the ordering requirements for memcg, and so the iterator may skip over initialized groups, or return partially initialized memcgs. The cgroup core can not reasonably provide a clear answer on whether the object around the css has been fully initialized, as that depends on controller-specific locking and lifetime rules. Thus, introduce a memcg-specific flag that is set after the memcg has been initialized in css_online(), and read before mem_cgroup_iter() callers access the memcg members. Signed-off-by:

commit 5b6b7490 upstream. Sometimes we need to program PLLs with a fixed rate configuration during driver probe. Doing this after we register the PLLs with the clock framework causes the common clock framework to assume the rate of the PLLs are 0. This causes all sorts of problems for rate recalculations because the common clock framework caches the rate once at registration time unless a flag is set to always recalculate the rates. Split the qcom_cc_probe() function into two pieces, map and everything else, so that drivers which need to configure some PLL rates or otherwise twiddle bits in the clock controller can do so before registering clocks. This allows us to properly detect the rates of PLLs that are programmed at boot. Fixes: 49fc825f "clk: qcom: Consolidate common probe code" 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 36de9286 upstream. If we run into some kind of error, such as ENOMEM, while calling ext4_getblk() or ext4_dx_find_entry(), we need to make sure this error gets propagated up to ext4_find_entry() and then to its callers. This way, transient errors such as ENOMEM can get propagated to the VFS. This is important so that the system calls return the appropriate error, and also so that in the case of ext4_lookup(), we return an error instead of a NULL inode, since that will result in a negative dentry cache entry that will stick around long past the OOM condition which caused a transient ENOMEM error.

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 7878289b upstream. Commit "mmc: mmci: Handle CMD irq before DATA irq", caused an issue when using the ARM model of the PL181 and running QEMU. The bug was reported for the following QEMU version: $ qemu-system-arm -version QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.1), Copyright (c) 2003-2008 Fabrice Bellard To resolve the problem, let's restore the old behavior were the DATA irq is handled prior the CMD irq, but only for the arm_variant, which the problem was reported for.

commit eb90b0c7 upstream. commit fc604767 ("ipvs: changes for local real server") from 2.6.37 introduced DNAT support to local real server but the IPv6 LOCAL_OUT handler ip_vs_local_reply6() is registered incorrectly as IPv4 hook causing any outgoing IPv4 traffic to be dropped depending on the IP header values. Chris tracked down the problem to CONFIG_IP_VS_IPV6=y Bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349768Reported-by:

commit caa8ad94 upstream. There's actually no good reason why we cannot use cgroup id 0, so lets just remove this artificial barrier. Reported-by:

commit 76f084bc upstream. Previously, only the four high bits of the tclass were maintained in the ipv6 case. This matches the behavior of ipv4, though whether or not we should reflect ECN bits may be up for debate. Signed-off-by:
