Re: make a confirm for [usb: dwc3: gadget: skip Set/Clear Halt when invalid]

by Felipe Balbi

Hi, that patch is not 100% correct. You can revert it in your tree. I added that because of a problem I found when running adb against macOS. It's actually okay to send Clear Halt at any time, but for some reason dwc3 was hanging when running adb against macOS. If you can revert the patch and make sure it works against all 3 major OSes (linux, windows and mac) I'd be really glad. liangshengjun <liangshengjun(a)hisilicon.com> writes: > Hi felipe, > > I have met a case about set/clear Halt patch > Version: linux v4.16, > Case: usb uvc run with bulk-mode connect to Windows 7 PC.

[PATCH v2 5/9] mtd: nand: atmel: fix OF child-node lookup

by Johan Hovold

Use the new of_get_compatible_child() helper to lookup the nfc child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the node of the device being probed). While at it, also fix a related nfc-node reference leak.

Patch to consider for stable 3.18, 4.4 and 4.9

by Tomasz Kramkowski

In September last year, Ben Hutchings submitted commit [9547837bdccb] for 3.16.48-rc1 and I informed him that it would be useless without [3f3752705dbd] (and that maybe [c3883fe06488] would be useful as well). Ben dropped the patch but suggested I email this list with the information of the other two patches but I never quite got around to it. Now I see Sasha Levin is submitting [3f3752705dbd] and [c3883fe06488] for 4.9, 4.4 and 3.18 it would now make sense to include [9547837bdccb]. This patch fixes a minor problem where a certain USB adapter for Sega Genesis controllers appears as one input device when it has two ports for two controllers. I imagine some users of emulator distributions might use stable kernels and might benefit from this fix. I'm actually not entirely sure that patch is something suitable for stable but since it was already submitted once then I don't think it hurts to bring it up again (despite it breaking stable-kernel-rules as far as I understand it). Commits mentioned: [9547837bdccb]: HID: usbhid: add quirk for innomedia INNEX GENESIS/ATARI adapter [3f3752705dbd]: HID: reject input outside logical range only if null state is set [c3883fe06488]: HID: clamp input to logical range if no null state If the patch [9547837bdccb] is not relevant then feel free to ignore this email. Thanks, -- Tomasz Kramkowski

[PATCH 3.16, 4.4, 4.9] dm bufio: drop the lock when doing GFP_NOIO allocation

This is backport of the upstream patch 41c73a49df31151f4ff868f28fe4f129f113fa2c.

[PATCH 3.16, 4.4, 4.9] dm bufio: avoid sleeping while holding the dm_bufio lock

by Mikulas Patocka

This is backport of the upstream patch 9ea61cac0b1ad0c09022f39fd97e9b99a2cfc2dc. It should be backported to stable kernels because this performance problem was seen on the android 4.4 kernel. commit 9ea61cac0b1ad0c09022f39fd97e9b99a2cfc2dc Author: Douglas Anderson <dianders(a)chromium.org> Date: Thu Nov 17 11:24:20 2016 -0800 dm bufio: avoid sleeping while holding the dm_bufio lock We've seen in-field reports showing _lots_ (18 in one case, 41 in another) of tasks all sitting there blocked on: mutex_lock+0x4c/0x68 dm_bufio_shrink_count+0x38/0x78 shrink_slab.part.54.constprop.65+0x100/0x464 shrink_zone+0xa8/0x198 In the two cases analyzed, we see one task that looks like this: Workqueue: kverityd verity_prefetch_io __switch_to+0x9c/0xa8 __schedule+0x440/0x6d8 schedule+0x94/0xb4 schedule_timeout+0x204/0x27c schedule_timeout_uninterruptible+0x44/0x50 wait_iff_congested+0x9c/0x1f0 shrink_inactive_list+0x3a0/0x4cc shrink_lruvec+0x418/0x5cc shrink_zone+0x88/0x198 try_to_free_pages+0x51c/0x588 __alloc_pages_nodemask+0x648/0xa88 __get_free_pages+0x34/0x7c alloc_buffer+0xa4/0x144 __bufio_new+0x84/0x278 dm_bufio_prefetch+0x9c/0x154 verity_prefetch_io+0xe8/0x10c process_one_work+0x240/0x424 worker_thread+0x2fc/0x424 kthread+0x10c/0x114 ...and that looks to be the one holding the mutex. The problem has been reproduced on fairly easily: 0. Be running Chrome OS w/ verity enabled on the root filesystem 1. Pick test patch: http://crosreview.com/412360 2. Install launchBalloons.sh and balloon.arm from http://crbug.com/468342 ...that's just a memory stress test app. 3. On a 4GB rk3399 machine, run nice ./launchBalloons.sh 4 900 100000 ...that tries to eat 4 * 900 MB of memory and keep accessing. 4. Login to the Chrome web browser and restore many tabs With that, I've seen printouts like: DOUG: long bufio 90758 ms ...and stack trace always show's we're in dm_bufio_prefetch(). The problem is that we try to allocate memory with GFP_NOIO while we're holding the dm_bufio lock. Instead we should be using GFP_NOWAIT. Using GFP_NOIO can cause us to sleep while holding the lock and that causes the above problems. The current behavior explained by David Rientjes: It will still try reclaim initially because __GFP_WAIT (or __GFP_KSWAPD_RECLAIM) is set by GFP_NOIO. This is the cause of contention on dm_bufio_lock() that the thread holds. You want to pass GFP_NOWAIT instead of GFP_NOIO to alloc_buffer() when holding a mutex that can be contended by a concurrent slab shrinker (if count_objects didn't use a trylock, this pattern would trivially deadlock). This change significantly increases responsiveness of the system while in this state. It makes a real difference because it unblocks kswapd. In the bug report analyzed, kswapd was hung: kswapd0 D ffffffc000204fd8 0 72 2 0x00000000 Call trace: [<ffffffc000204fd8>] __switch_to+0x9c/0xa8 [<ffffffc00090b794>] __schedule+0x440/0x6d8 [<ffffffc00090bac0>] schedule+0x94/0xb4 [<ffffffc00090be44>] schedule_preempt_disabled+0x28/0x44 [<ffffffc00090d900>] __mutex_lock_slowpath+0x120/0x1ac [<ffffffc00090d9d8>] mutex_lock+0x4c/0x68 [<ffffffc000708e7c>] dm_bufio_shrink_count+0x38/0x78 [<ffffffc00030b268>] shrink_slab.part.54.constprop.65+0x100/0x464 [<ffffffc00030dbd8>] shrink_zone+0xa8/0x198 [<ffffffc00030e578>] balance_pgdat+0x328/0x508 [<ffffffc00030eb7c>] kswapd+0x424/0x51c [<ffffffc00023f06c>] kthread+0x10c/0x114 [<ffffffc000203dd0>] ret_from_fork+0x10/0x40 By unblocking kswapd memory pressure should be reduced.

[PATCH RESEND] ocfs2: fix a misuse a of brelse after failing ocfs2_check_dir_entry

by Changwei Ge

From: Changwei Ge <ge.changwei(a)h3c.com> Somehow, file system metadata was corrupted, which causes ocfs2_check_dir_entry() to fail in function ocfs2_dir_foreach_blk_el(). According to the original design intention, if above happens we should skip the problematic block and continue to retrieve dir entry. But there is obviouse misuse of brelse around related code. After failure of ocfs2_check_dir_entry(), currunt code just moves to next position and uses the problematic buffer head again and again during which the problematic buffer head is released for multiple times. I suppose, this a serious issue which is long-lived in ocfs2. This may cause other file systems which is also used in a the same host insane. So we should also consider about bakcporting this patch into linux -stable.
