ee0ed02 Jan Kara 24 May 2019, 03:35:28 UTC ext4: do not delete unlinked inode from orphan list on failed truncate It is possible that unlinked inode enters ext4_setattr() (e.g. if somebody calls ftruncate(2) on unlinked but still open file).

7996a8b Bob Liu 21 May 2019, 03:25:55 UTC blk-mq: fix hang caused by freeze/unfreeze sequence The following is a description of a hang in blk_mq_freeze_queue_wait(). The hang happens on attempt to freeze a queue while another task does queue unfreeze. The root cause is an incorrect sequence of percpu_ref_resurrect() and percpu_ref_kill() and as a result those two can be swapped: CPU#0 CPU#1 ---------------- ----------------- q1 = blk_mq_init_queue(shared_tags) q2 = blk_mq_init_queue(shared_tags): blk_mq_add_queue_tag_set(shared_tags): blk_mq_update_tag_set_depth(shared_tags): list_for_each_entry() blk_mq_freeze_queue(q1) > percpu_ref_kill() > blk_mq_freeze_queue_wait() blk_cleanup_queue(q1) blk_mq_freeze_queue(q1) > percpu_ref_kill() ^^^^^^ freeze_depth can't guarantee the order blk_mq_unfreeze_queue() > percpu_ref_resurrect() > blk_mq_freeze_queue_wait() ^^^^^^ Hang here!!!! This wrong sequence raises kernel warning: percpu_ref_kill_and_confirm called more than once on blk_queue_usage_counter_release! WARNING: CPU: 0 PID: 11854 at lib/percpu-refcount.c:336 percpu_ref_kill_and_confirm+0x99/0xb0 But the most unpleasant effect is a hang of a blk_mq_freeze_queue_wait(), which waits for a zero of a q_usage_counter, which never happens because percpu-ref was reinited (instead of being killed) and stays in PERCPU state forever. How to reproduce: - "insmod null_blk.ko shared_tags=1 nr_devices=0 queue_mode=2" - cpu0: python Script.py 0; taskset the corresponding process running on cpu0 - cpu1: python Script.py 1; taskset the corresponding process running on cpu1 Script.py: ------ #!/usr/bin/python3 import os import sys while True: on = "echo 1 > /sys/kernel/config/nullb/%s/power" % sys.argv[1] off = "echo 0 > /sys/kernel/config/nullb/%s/power" % sys.argv[1] os.system(on) os.system(off) ------ This bug was first reported and fixed by Roman, previous discussion: [1] Message id: 1443287365-4244-7-git-send-email-akinobu.mita@gmail.com [2] Message id: 1443563240-29306-6-git-send-email-tj@kernel.org [3] https://patchwork.kernel.org/patch/9268199/ Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Ming Lei <ming.lei@redhat.com> Reviewed-by: Bart Van Assche <bvanassche@acm.org> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Roman Pen <roman.penyaev@profitbricks.com> Signed-off-by: Bob Liu <bob.liu@oracle.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> 23 May 2019, 16:25:26 UTC

eded341 Christoph Hellwig 21 May 2019, 07:01:40 UTC block: don't decrement nr_phys_segments for physically contigous segments Currently ll_merge_requests_fn, unlike all other merge functions, reduces nr_phys_segments by one if the last segment of the previous, and the first segment of the next segement are contigous. While this seems like a nice solution to avoid building smaller than possible requests it causes a mismatch between the segments actually present in the request and those iterated over by the bvec iterators, including __rq_for_each_bio. This can for example mistrigger the single segment optimization in the nvme-pci driver, and might lead to mismatching nr_phys_segments number when recalculating the number of request when inserting a cloned request. We could possibly work around this by making the bvec iterators take the front and back segment size into account, but that would require moving them from the bio to the bio_iter and spreading this mess over all users of bvecs. Or we could simply remove this optimization under the assumption that most users already build good enough bvecs, and that the bio merge patch never cared about this optimization either. The latter is what this patch does. dff824b2aadb ("nvme-pci: optimize mapping of small single segment requests").

b2eed9b Ard Biesheuvel 23 May 2019, 09:17:37 UTC arm64/kernel: kaslr: reduce module randomization range to 2 GB The following commit 7290d5809571 ("module: use relative references for __ksymtab entries") updated the ksymtab handling of some KASLR capable architectures so that ksymtab entries are emitted as pairs of 32-bit relative references. This reduces the size of the entries, but more importantly, it gets rid of statically assigned absolute addresses, which require fixing up at boot time if the kernel is self relocating (which takes a 24 byte RELA entry for each member of the ksymtab struct). Since ksymtab entries are always part of the same module as the symbol they export, it was assumed at the time that a 32-bit relative reference is always sufficient to capture the offset between a ksymtab entry and its target symbol. Unfortunately, this is not always true: in the case of per-CPU variables, a per-CPU variable's base address (which usually differs from the actual address of any of its per-CPU copies) is allocated in the vicinity of the ..data.percpu section in the core kernel (i.e., in the per-CPU reserved region which follows the section containing the core kernel's statically allocated per-CPU variables). Since we randomize the module space over a 4 GB window covering the core kernel (based on the -/+ 4 GB range of an ADRP/ADD pair), we may end up putting the core kernel out of the -/+ 2 GB range of 32-bit relative references of module ksymtab entries that refer to per-CPU variables. So reduce the module randomization range a bit further. We lose 1 bit of randomization this way, but this is something we can tolerate.

Otherwise we'd hit the following warning when the device is using MSI: WARNING: CPU: 4 PID: 7 at drivers/pci/msi.c:1272 pci_irq_get_affinity+0x66/0x80 Modules linked in: nvme nvme_core serio_raw CPU: 4 PID: 7 Comm: kworker/u16:0 Tainted: G W 5.2.0-rc1+ #494 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.1-0-ga5cab58e9a3f-prebuilt.qemu.org 04/01/2014 Workqueue: nvme-reset-wq nvme_reset_work [nvme] RIP: 0010:pci_irq_get_affinity+0x66/0x80 Code: 0b 31 c0 c3 83 e2 10 48 c7 c0 b0 83 35 91 74 2a 48 8b 87 d8 03 00 00 48 85 c0 74 0e 48 8b 50 30 48 85 d2 74 05 39 70 14 77 05 <0f> 0b 31 c0 c3 48 63 f6 48 8d 04 76 48 8d 04 c2 f3 c3 48 8b 40 30 RSP: 0000:ffffb5abc01d3cc8 EFLAGS: 00010246 RAX: ffff9536786a39c0 RBX: 0000000000000000 RCX: 0000000000000080 RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff9536781ed000 RBP: ffff95367346a008 R08: ffff95367d43f080 R09: ffff953678c07800 R10: ffff953678164800 R11: 0000000000000000 R12: 0000000000000000 R13: ffff9536781ed000 R14: 00000000ffffffff R15: ffff95367346a008 FS: 0000000000000000(0000) GS:ffff95367d400000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fdf814a3ff0 CR3: 000000001a20f000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: blk_mq_pci_map_queues+0x37/0xd0 nvme_pci_map_queues+0x80/0xb0 [nvme] blk_mq_alloc_tag_set+0x133/0x2f0 nvme_reset_work+0x105d/0x1590 [nvme] process_one_work+0x291/0x530 worker_thread+0x218/0x3d0 ? process_one_work+0x530/0x530 kthread+0x111/0x130 ? kthread_park+0x90/0x90 ret_from_fork+0x1f/0x30 ---[ end trace 74587339d93c83c0 ]--- Fixes: 22b5560195bd6 ("nvme-pci: Separate IO and admin queue IRQ vectors") Reported-by: Iván Chavero <ichavero@chavero.com.mx> Reviewed-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Keith Busch <keith.busch@intel.com> 22 May 2019, 16:11:36 UTC

The crash happens roughly 125..130ms after the disconnect. This correlates with the 'delay' timer that is started on certain USB tx/rx errors in the URB completion handler. The problem is a race of usbnet_stop() with usbnet_start_xmit(). In usbnet_stop() we call usbnet_terminate_urbs() to cancel all URBs in flight. This only makes sense if no new URBs are submitted concurrently, though. But the usbnet_start_xmit() can run at the same time on another CPU which almost unconditionally submits an URB. The error callback of the new URB will then schedule the timer after it was already stopped. The fix adds a check if the tx queue is stopped after the tx list lock has been taken. This should reliably prevent the submission of new URBs while usbnet_terminate_urbs() does its job. The same thing is done on the rx side even though it might be safe due to other flags that are checked there. Signed-off-by: Jan Klötzke <Jan.Kloetzke@preh.de> Signed-off-by: David S.

Bug: In ipheth_tx(), netif_wake_queue() may be called on the callback ipheth_sndbulk_callback(), _before_ netif_stop_queue() is called. When this happens, the queue is stopped longer than it needs to be, thus reducing network performance. Fix: Move netif_stop_queue() in front of usb_submit_urb(). Now the order is always correct. In case, usb_submit_urb() fails, the queue is woken up again as callback will not fire. Testing: This racing condition is usually not noticeable, as it has to occur very frequently to slowdown the network. The callback from the USB is usually triggered slow enough, so the situation does not appear.

These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up. These diffstats are not small, 3840 files are touched, over 10k lines removed in just 24 patches" * tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (24 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 25 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 24 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 23 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 22 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 21 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 20 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 19 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 18 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 17 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 15 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 14 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 13 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 12 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 11 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 10 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 9 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 7 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 5 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 4 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 3 ... 21 May 2019, 19:33:38 UTC

9b2ca37 Tom Zanussi 18 April 2019, 15:18:52 UTC tracing: Add a check_val() check before updating cond_snapshot() track_val Without this check a snapshot is taken whenever a bucket's max is hit, rather than only when the global max is hit, as it should be. Before: In this example, we do a first run of the workload (cyclictest), examine the output, note the max ('triggering value') (347), then do a second run and note the max again. In this case, the max in the second run (39) is below the max in the first run, but since we haven't cleared the histogram, the first max is still in the histogram and is higher than any other max, so it should still be the max for the snapshot. It isn't however - the value should still be 347 after the second run. # echo 'hist:keys=pid:ts0=common_timestamp.usecs if comm=="cyclictest"' >> /sys/kernel/debug/tracing/events/sched/sched_waking/trigger # echo 'hist:keys=next_pid:wakeup_lat=common_timestamp.usecs-$ts0:onmax($wakeup_lat).save(next_prio,next_comm,prev_pid,prev_prio,prev_comm):onmax($wakeup_lat).snapshot() if next_comm=="cyclictest"' >> /sys/kernel/debug/tracing/events/sched/sched_switch/trigger # cyclictest -p 80 -n -s -t 2 -D 2 # cat /sys/kernel/debug/tracing/events/sched/sched_switch/hist { next_pid: 2143 } hitcount: 199 max: 44 next_prio: 120 next_comm: cyclictest prev_pid: 0 prev_prio: 120 prev_comm: swapper/4 { next_pid: 2145 } hitcount: 1325 max: 38 next_prio: 19 next_comm: cyclictest prev_pid: 0 prev_prio: 120 prev_comm: swapper/2 { next_pid: 2144 } hitcount: 1982 max: 347 next_prio: 19 next_comm: cyclictest prev_pid: 0 prev_prio: 120 prev_comm: swapper/6 Snapshot taken (see tracing/snapshot).

c8d94a1 Tom Zanussi 18 April 2019, 15:18:51 UTC tracing: Check keys for variable references in expressions too There's an existing check for variable references in keys, but it doesn't go far enough. It checks whether a key field is a variable reference but doesn't check whether it's an expression containing variable references, which can cause the same problems for callers. Use the existing field_has_hist_vars() function rather than a direct top-level flag check to catch all possible variable references.
