2018-12-06mm, thp: restore node-local hugepage allocationsDavid Rientjes3-29/+17
This is a full revert of ac5b2c18911f ("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings") and a partial revert of 89c83fb539f9 ("mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask"). By not setting __GFP_THISNODE, applications can allocate remote hugepages when the local node is fragmented or low on memory when either the thp defrag setting is "always" or the vma has been madvised with MADV_HUGEPAGE. Remote access to hugepages often has much higher latency than local pages of the native page size. On Haswell, ac5b2c18911f was shown to have a 13.9% access regression after this commit for binaries that remap their text segment to be backed by transparent hugepages. The intent of ac5b2c18911f is to address an issue where a local node is low on memory or fragmented such that a hugepage cannot be allocated. In every scenario where this was described as a fix, there is abundant and unfragmented remote memory available to allocate from, even with a greater access latency. If remote memory is also low or fragmented, not setting __GFP_THISNODE was also measured on Haswell to have a 40% regression in allocation latency. Restore __GFP_THISNODE for thp allocations.

2018-12-05Revert "mfd: cros_ec: Use devm_kzalloc for private data"Enric Balletbo i Serra1-1/+7
This reverts commit 3aa2177e47878f7e7616da8a2050c44f22301b6e. That commit triggered a new WARN when unloading the module (see at the end of the commit message). When a class_dev is embedded in a structure then that class_dev is the thing that controls the lifetime of that structure, for that reason device managed allocations can't be used here. See Documentation/kobject.txt. Revert the above patch, so the struct is allocated using kzalloc and we have a release function for it that frees the allocated memory, otherwise it is broken. ------------[ cut here ]------------ Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

2018-12-05blk-mq: fix corruption with direct issueJens Axboe1-1/+25
If we attempt a direct issue to a SCSI device, and it returns BUSY, then we queue the request up normally. However, the SCSI layer may have already setup SG tables etc for this particular command. If we later merge with this request, then the old tables are no longer valid. Once we issue the IO, we only read/write the original part of the request, not the new state of it. This causes data corruption, and is most often noticed with the file system complaining about the just read data being invalid: [ 235.934465] EXT4-fs error (device sda1): ext4_iget:4831: inode #7142: comm dpkg-query: bad extra_isize 24937 (inode size 256) because most of it is garbage... This doesn't happen from the normal issue path, as we will simply defer the request to the hardware queue dispatch list if we fail. Once it's on the dispatch list, we never merge with it. Fix this from the direct issue path by flagging the request as REQ_NOMERGE so we don't change the size of it before issue.

2018-12-04btrfs: tree-checker: Don't check max block group size as current max chunk ↵Qu Wenruo1-5/+3
size limit is unreliable [BUG] A completely valid btrfs will refuse to mount, with error message like: BTRFS critical (device sdb2): corrupt leaf: root=2 block=239681536 slot=172 \ bg_start=12018974720 bg_len=10888413184, invalid block group size, \ have 10888413184 expect (0, 10737418240] This has been reported several times as the 4.19 kernel is now being used. The filesystem refuses to mount, but is otherwise ok and booting 4.18 is a workaround. Btrfs check returns no error, and all kernels used on this fs is later than 2011, which should all have the 10G size limit commit. [CAUSE] For a 12 devices btrfs, we could allocate a chunk larger than 10G due to stripe stripe bump up. __btrfs_alloc_chunk() |- max_stripe_size = 1G |- max_chunk_size = 10G |- data_stripe = 11 |- if (1G * 11 > 10G) { stripe_size = 976128930; stripe_size = round_up(976128930, SZ_16M) = 989855744 However the final stripe_size (989855744) * 11 = 10888413184, which is still larger than 10G. [FIX] For the comprehensive check, we need to do the full check at chunk read time, and rely on bg <-> chunk mapping to do the check. We could just skip the length check for now.

I noticed that the Android v3.0.8 kernel on droid4 is using different keypad values from the mainline kernel and does not have issues with keys occasionally being stuck until pressed again. Turns out there was an earlier patch posted to fix this as "Input: omap-keypad: errata i689: Correct debounce time", but it was never reposted to fix use macros for timing calculations. This updated version is using macros, and also fixes the use of the input clock rate to use 32768KiHz instead of 32000KiHz. And we want to use the known good Android kernel values of 3 and 6 instead of 2 and 6 in the earlier patch.

2018-12-03ALSA: usb-audio: Fix UAF decrement if card has no live interfaces in card.cHui Peng1-1/+4
If a USB sound card reports 0 interfaces, an error condition is triggered and the function usb_audio_probe errors out. In the error path, there was a use-after-free vulnerability where the memory object of the card was first freed, followed by a decrement of the number of active chips. Moving the decrement above the atomic_dec fixes the UAF. [ The original problem was introduced in 3.1 kernel, while it was developed in a different form. The Fixes tag below indicates the original commit but it doesn't mean that the patch is applicable cleanly. -- tiwai ] Fixes: 362e4e49abe5 ("ALSA: usb-audio - clear chip->probing on error exit") Reported-by: Hui Peng <benquike@gmail.com> Reported-by: Mathias Payer <mathias.payer@nebelwelt.net> Signed-off-by: Hui Peng <benquike@gmail.com> Signed-off-by: Mathias Payer <mathias.payer@nebelwelt.net> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-12-03ALSA: hda/realtek - Fix speaker output regression on Thinkpad T570Takashi Iwai1-0/+9
We've got a regression report for some Thinkpad models (at least T570s) which shows the too low speaker output volume. The bisection leaded to the commit 61fcf8ece9b6 ("ALSA: hda/realtek - Enable Thinkpad Dock device for ALC298 platform"), and it's basically adding the two pin configurations for the dock, and looks harmless. The real culprit seems, though, that the DAC assignment for the speaker pin is implicitly assumed on these devices, i.e. pin NID 0x14 to be coupled with DAC NID 0x03. When more pins are configured by the commit above, the auto-parser changes the DAC assignment, and this resulted in the regression. As a workaround, just provide the fixed pin / DAC mapping table for this Thinkpad fixup function. It's no generic solution, but the problem itself is pretty much device-specific, so must be good enough.

The macros PCI_EXP_LNKCAP_SLS_*GB are values, not bit masks. We must mask the register and compare it against them. This fixes errors like this: amdgpu: [powerplay] failed to send message 261 ret is 0 when a PCIe-v3 card is plugged into a PCIe-v1 slot, because the slot is being incorrectly reported as PCIe-v3 capable. 6cf57be0f78e, which appeared in v4.17, added pcie_get_speed_cap() with the incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask. 5d9a63304032, which appeared in v4.19, changed amdgpu to use pcie_get_speed_cap(), so the amdgpu bug reports below are regressions in v4.19.
