20be493 Andreas Gruenbacher 26 May 2020, 18:11:51 UTC gfs2: Even more gfs2_find_jhead fixes Fix several issues in the previous gfs2_find_jhead fix: * When updating @blocks_submitted, @block refers to the first block block not submitted yet, not the last block submitted, so fix an off-by-one error. * We want to ensure that @blocks_submitted is far enough ahead of @blocks_read to guarantee that there is in-flight I/O. Otherwise, we'll eventually end up waiting for pages that haven't been submitted, yet. * It's much easier to compare the number of blocks added with the number of blocks submitted to limit the maximum bio size. * Even with bio chaining, we can keep adding blocks until we reach the maximum bio size, as long as we stop at a page boundary.

6988f31 Konstantin Khlebnikov 28 May 2020, 05:20:47 UTC mm: remove VM_BUG_ON(PageSlab()) from page_mapcount() Replace superfluous VM_BUG_ON() with comment about correct usage. Technically reverts commit 1d148e218a0d ("mm: add VM_BUG_ON_PAGE() to page_mapcount()"), but context lines have changed. Function isolate_migratepages_block() runs some checks out of lru_lock when choose pages for migration. After checking PageLRU() it checks extra page references by comparing page_count() and page_mapcount(). Between these two checks page could be removed from lru, freed and taken by slab. As a result this race triggers VM_BUG_ON(PageSlab()) in page_mapcount(). Race window is tiny. For certain workload this happens around once a year. page:ffffea0105ca9380 count:1 mapcount:0 mapping:ffff88ff7712c180 index:0x0 compound_mapcount: 0 flags: 0x500000000008100(slab|head) raw: 0500000000008100 dead000000000100 dead000000000200 ffff88ff7712c180 raw: 0000000000000000 0000000080200020 00000001ffffffff 0000000000000000 page dumped because: VM_BUG_ON_PAGE(PageSlab(page)) ------------[ cut here ]------------ kernel BUG at ./include/linux/mm.h:628! invalid opcode: 0000 [#1] SMP NOPTI CPU: 77 PID: 504 Comm: kcompactd1 Tainted: G W 4.19.109-27 #1 Hardware name: Yandex T175-N41-Y3N/MY81-EX0-Y3N, BIOS R05 06/20/2019 RIP: 0010:isolate_migratepages_block+0x986/0x9b0 The code in isolate_migratepages_block() was added in commit 119d6d59dcc0 ("mm, compaction: avoid isolating pinned pages") before adding VM_BUG_ON into page_mapcount().

1acba6a Valentine Fatiev 27 May 2020, 13:47:05 UTC IB/ipoib: Fix double free of skb in case of multicast traffic in CM mode When connected mode is set, and we have connected and datagram traffic in parallel, ipoib might crash with double free of datagram skb. The current mechanism assumes that the order in the completion queue is the same as the order of sent packets for all QPs. Order is kept only for specific QP, in case of mixed UD and CM traffic we have few QPs (one UD and few CM's) in parallel. The problem: ---------------------------------------------------------- Transmit queue: ----------------- UD skb pointer kept in queue itself, CM skb kept in spearate queue and uses transmit queue as a placeholder to count the number of total transmitted packets. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 .........127 ------------------------------------------------------------ NL ud1 UD2 CM1 ud3 cm2 cm3 ud4 cm4 ud5 NL NL NL ........... ------------------------------------------------------------ ^ ^ tail head Completion queue (problematic scenario) - the order not the same as in the transmit queue: 1 2 3 4 5 6 7 8 9 ------------------------------------ ud1 CM1 UD2 ud3 cm2 cm3 ud4 cm4 ud5 ------------------------------------ 1. CM1 'wc' processing - skb freed in cm separate ring. - tx_tail of transmit queue increased although UD2 is not freed. Now driver assumes UD2 index is already freed and it could be used for new transmitted skb. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 .........127 ------------------------------------------------------------ NL NL UD2 CM1 ud3 cm2 cm3 ud4 cm4 ud5 NL NL NL ........... ------------------------------------------------------------ ^ ^ ^ (Bad)tail head (Bad - Could be used for new SKB) In this case (due to heavy load) UD2 skb pointer could be replaced by new transmitted packet UD_NEW, as the driver assumes its free. At this point we will have to process two 'wc' with same index but we have only one pointer to free. During second attempt to free the same skb we will have NULL pointer exception. 2. UD2 'wc' processing - skb freed according the index we got from 'wc', but it was already overwritten by mistake. So actually the skb that was released is the skb of the new transmitted packet and not the original one. 3. UD_NEW 'wc' processing - attempt to free already freed skb. NUll pointer exception. The fix: ----------------------------------------------------------------------- The fix is to stop using the UD ring as a placeholder for CM packets, the cyclic ring variables tx_head and tx_tail will manage the UD tx_ring, a new cyclic variables global_tx_head and global_tx_tail are introduced for managing and counting the overall outstanding sent packets, then the send queue will be stopped and waken based on these variables only. Note that no locking is needed since global_tx_head is updated in the xmit flow and global_tx_tail is updated in the NAPI flow only. A previous attempt tried to use one variable to count the outstanding sent packets, but it did not work since xmit and NAPI flows can run at the same time and the counter will be updated wrongly. Thus, we use the same simple cyclic head and tail scheme that we have today for the UD tx_ring.

9210c07 Dongli Zhang 27 May 2020, 16:13:52 UTC nvme-pci: avoid race between nvme_reap_pending_cqes() and nvme_poll() There may be a race between nvme_reap_pending_cqes() and nvme_poll(), e.g., when doing live reset while polling the nvme device. CPU X CPU Y nvme_poll() nvme_dev_disable() -> nvme_stop_queues() -> nvme_suspend_io_queues() -> nvme_suspend_queue() -> spin_lock(&nvmeq->cq_poll_lock); -> nvme_reap_pending_cqes() -> nvme_process_cq() -> nvme_process_cq() In the above scenario, the nvme_process_cq() for the same queue may be running on both CPU X and CPU Y concurrently. It is much more easier to reproduce the issue when CONFIG_PREEMPT is enabled in kernel. When CONFIG_PREEMPT is disabled, it would take longer time for nvme_stop_queues()-->blk_mq_quiesce_queue() to wait for grace period. This patch protects nvme_process_cq() with nvmeq->cq_poll_lock in nvme_reap_pending_cqes().

7f5ad9c Takashi Iwai 26 May 2020, 08:28:10 UTC ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audio Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices, a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC (USB ID 0414:a000). The latter serves solely for the headphone output on the front panel while the former serves for the rest I/Os (mostly for the I/Os in the rear panel but also including the front mic). Both chips do work more or less with the unmodified USB-audio driver, but there are a few glitches. The ALC1220-VB returns an error for an inquiry to some jacks, as already seen on other TRX40-based mobos. However this machine has a slightly incompatible configuration, hence the existing mapping cannot be used as is. Meanwhile the ESS chip seems working without any quirk. But since both audio devices don't provide any specific names, both cards appear as "USB-Audio", and it's quite confusing for users. This patch is an attempt to overcome those issues: - The specific mapping table for ALC1220-VB is provided, reducing the non-working nodes and renaming the badly chosen controls. The connector map isn't needed here unlike other TRX40 quirks. - For both USB IDs (0414:a000 and 0414:a001), provide specific card name strings, so that user-space can identify more easily; and more importantly, UCM profile can be applied to each.

a4ae32c Eric W. Biederman 25 May 2020, 17:56:15 UTC exec: Always set cap_ambient in cap_bprm_set_creds An invariant of cap_bprm_set_creds is that every field in the new cred structure that cap_bprm_set_creds might set, needs to be set every time to ensure the fields does not get a stale value. The field cap_ambient is not set every time cap_bprm_set_creds is called, which means that if there is a suid or sgid script with an interpreter that has neither the suid nor the sgid bits set the interpreter should be able to accept ambient credentials. Unfortuantely because cap_ambient is not reset to it's original value the interpreter can not accept ambient credentials. Given that the ambient capability set is expected to be controlled by the caller, I don't think this is particularly serious. But it is definitely worth fixing so the code works correctly. I have tested to verify my reading of the code is correct and the interpreter of a sgid can receive ambient capabilities with this change and cannot receive ambient capabilities without this change.

399c01a Takashi Iwai 26 May 2020, 06:24:06 UTC ALSA: hda/realtek - Add a model for Thinkpad T570 without DAC workaround We fixed the regression of the speaker volume for some Thinkpad models (e.g. T570) by the commit 54947cd64c1b ("ALSA: hda/realtek - Fix speaker output regression on Thinkpad T570"). Essentially it fixes the DAC / pin pairing by a static table. It was confirmed and merged to stable kernel later. Now, interestingly, we got another regression report for the very same model (T570) about the similar problem, and the commit above was the culprit. That is, by some reason, there are devices that prefer the DAC1, and another device DAC2! Unfortunately those have the same ID and we have no idea what can differentiate, in this patch, a new fixup model "tpt470-dock-fix" is provided, so that users with such a machine can apply it manually. When model=tpt470-dock-fix option is passed to snd-hda-intel module, it avoids the fixed DAC pairing and the DAC1 is assigned to the speaker like the earlier versions.

a16b8e0 Roi Dayan 30 April 2020, 06:16:01 UTC net/mlx5e: Fix inner tirs handling In the cited commit inner_tirs argument was added to create and destroy inner tirs, and no indication was added to mlx5e_modify_tirs_hash() function. In order to have a consistent handling, use inner_indir_tir[0].tirn in tirs destroy/modify function as an indication to whether inner tirs are created. Inner tirs are not created for representors and before this commit, a call to mlx5e_modify_tirs_hash() was sending HW commands to modify non-existent inner tirs.
