[PATCH 1/4] cputime, cpuacct: Include guest time in user time in cpuacct.stat

by Andrey Ryabinin

cpuacct.stat in no-root cgroups shows user time without guest time included int it. This doesn't match with user time shown in root cpuacct.stat and /proc/<pid>/stat. Make account_guest_time() to add user time to cgroup's cpustat to fix this.

Checking the mitigation itself is not sufficient as it can be toggled on at any time and KVM doesn't reset MMU contexts when that happens. KVM could reset the contexts, but that would require purging all SPTEs in all MMUs, for no real benefit. And, KVM already forces EFER.NX=1 when TDP is disabled (for WP=0, SMEP=1, NX=0), so technically NX is never reserved for shadow MMUs.

stable 5.4.135 REGRESSION / once-a-day WARNING: at kthread_is_per_cpu+0x1c/0x20

by bof＠bof.de

Hi, first regression report in a long while... hope I'm doing this right. I run self-build, from time to time, mainline kernels, in production, both on HP DL hosts + inside kvm VMs on these. I usually stick to a certain long term stable line for a year or three. As such, for a bit longer already, I'm running 5.4, starting somewhere at 5.4.4x. At the moment, I started to roll out 5.4.135 on a few of the hosts, and encounter a rare "WARNING: CPU ... PID ... at kthread_is_per_cpu+0x1c/0x20" splat (see full dmesg below) Previous kernel I was running there, never seeing that, was 5.4.114 Searching a bit, turns up this 5.4.118 commit / backport: https://lore.kernel.org/stable/162074016514831@kroah.com/ https://lore.kernel.org/lkml/20210407220628.3798191-2-valentin.schneider@ar… pointing to exactly the place shown in the dmesg trace. So far, this happened on two out of three updated webservers, at uptimes 71828 seconds and 92993 seconds, both times "under" an httpd-prefork process. Apart from that WARNING, I don't see any user affecting regression. Further workload information: these VMs are webservers, each running a constant load of around 6 out of 14 cores, serving about 5000 reqs/minute (apache prefork + mod_php) with a bit of local redis around. The hosts they run on, are not much overbooked, one other VM running along, overall load around 13 out of 20 real cores (no HT). Find below, the dmesg output of one of these WARNING dumps, and the kernel config I'm using there. Hope this makes sense to someone who understands these code areas. best regards Patrick [71828.149058] ------------[ cut here ]------------ [71828.149074] WARNING: CPU: 3 PID: 28387 at kthread_is_per_cpu+0x1c/0x20 [71828.149078] Modules linked in: [71828.149082] CPU: 3 PID: 28387 Comm: httpd-prefork Not tainted 5.4.135-vm #2 [71828.149083] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.13.0-0-gf21b5a4-rebuilt.opensuse.org 04/01/2014 [71828.149086] RIP: 0010:kthread_is_per_cpu+0x1c/0x20 [71828.149092] Code: eb d7 0f 0b eb e7 0f 1f 84 00 00 00 00 00 f6 47 26 20 74 16 48 8b 87 b0 04 00 00 48 85 c0 74 07 48 8b 00 83 e0 01 c3 31 c0 c3 <0f> 0b eb e6 53 48 83 ec 08 f6 47 26 20 74 4b 48 8b 9f b0 04 00 00 [71828.149093] RSP: 0018:ffffc9000a2b3888 EFLAGS: 00010046 [71828.149095] RAX: 0000000000000003 RBX: ffffc9000a2b38f8 RCX: 00000000061205e4 [71828.149095] RDX: ffff8897d9411670 RSI: ffffc9000a2b38f8 RDI: ffff88970363a500 [71828.149096] RBP: ffff88970363a500 R08: 00000029273da8f2 R09: ffff8897d8da9e40 [71828.149097] R10: 0000000000000000 R11: 0000000000000400 R12: 0000000000000000 [71828.149098] R13: ffff88970363a500 R14: ffff8897df9e7550 R15: ffff8897df9e6b40 [71828.149102] FS: 00007f3a9bd09800(0000) GS:ffff8897df8c0000(0000) knlGS:0000000000000000 [71828.149102] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [71828.149103] CR2: 00007f79aa9a44a8 CR3: 00000017103c4006 CR4: 0000000000160ea0 [71828.149104] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [71828.149105] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [71828.149109] Call Trace: [71828.149115] can_migrate_task+0xc2/0x170 [71828.149118] load_balance+0x34f/0x950 [71828.149120] newidle_balance+0x136/0x310 [71828.149121] pick_next_task_fair+0x2e/0x2f0 [71828.149149] __schedule+0xda/0x530 [71828.149153] ? hrtimer_start_range_ns+0x181/0x2a0 [71828.149155] schedule+0x34/0xa0 [71828.149157] schedule_hrtimeout_range_clock+0x7f/0xe0 [71828.149158] ? __hrtimer_init+0x90/0x90 [71828.149161] poll_schedule_timeout.constprop.0+0x3d/0x60 [71828.149163] do_sys_poll+0x3c6/0x4d0 [71828.149178] ? ip_output+0x5c/0xd0 [71828.149179] ? __ip_finish_output+0x200/0x200 [71828.149180] ? __ip_queue_xmit+0x151/0x3c0 [71828.149182] ? lock_timer_base+0x5c/0x80 [71828.149187] ? __tcp_transmit_skb+0x53d/0xa90 [71828.149189] ? poll_select_finish+0x1e0/0x1e0 [71828.149204] ? _copy_from_iter_full+0x8a/0x280 [71828.149205] ? __tcp_push_pending_frames+0x2d/0xb0 [71828.149208] ? tcp_sendmsg_locked+0x3b6/0xd90 [71828.149212] ? release_sock+0x3e/0x90 [71828.149213] ? _raw_spin_unlock_bh+0x5/0x20 [71828.149215] ? tcp_sendmsg+0x2e/0x40 [71828.149216] ? __sys_sendto+0x14b/0x160 [71828.149217] ? _raw_spin_unlock_bh+0x5/0x20 [71828.149219] ? sock_setsockopt+0xba/0xcc0 [71828.149223] ? kvm_clock_get_cycles+0xd/0x10 [71828.149225] ? ktime_get_ts64+0x41/0xe0 [71828.149226] __x64_sys_poll+0x75/0x120 [71828.149228] do_syscall_64+0x43/0x100 [71828.149230] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [71828.149232] RIP: 0033:0x7f3a9c048a93 [71828.149234] Code: 49 8b 45 10 5d 41 5c 41 5d 41 5e c3 66 2e 0f 1f 84 00 00 00 00 00 90 64 8b 04 25 18 00 00 00 85 c0 75 14 b8 07 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 55 c3 0f 1f 40 00 48 83 ec 28 89 54 24 1c 48 [71828.149235] RSP: 002b:00007ffc3d3557a8 EFLAGS: 00000246 ORIG_RAX: 0000000000000007 [71828.149236] RAX: ffffffffffffffda RBX: 0000560f09ca2cc8 RCX: 00007f3a9c048a93 [71828.149237] RDX: 0000000057b12c00 RSI: 0000000000000001 RDI: 00007ffc3d3557c8 [71828.149238] RBP: 0000560f09cac1f8 R08: 0000000000000004 R09: 0000000000000000 [71828.149239] R10: 0000560f09cabf68 R11: 0000000000000246 R12: 0000560f09bb7d67 [71828.149240] R13: 000000000000005a R14: 00007ffc3d3557c8 R15: 20c49ba5e353f7cf #

[PATCH] rtc: mc146818: Use hours for checking RTC availability

by Mateusz Jończyk

To prevent an infinite loop, it is necessary to ascertain the RTC is present. Previous code was checking if bit 6 in register 0x0D is cleared. This caused a false negative on a motherboard with an AMD SB710 southbridge; according to the specification [1], bit 6 of register 0x0D on this chipset is a scratchbit. Use the RTC_HOURS register instead, which is expected to contain a value not larger then 24, in BCD format. Caveat: when I was playing with while true; do cat /sys/class/rtc/rtc0/time; done I sometimes triggered this mechanism on my HP laptop. It appears that CMOS_READ(RTC_VALID) was sometimes reading the number of seconds from previous loop iteration. This happens very rarely, though, and this patch does not make it any more likely.

[PATCH] PCI: Add Max Payload Size quirk for ASMedia ASM1062 SATA controller

by Marek Behún

The ASMedia ASM1062 SATA controller causes an External Abort on controllers which support Max Payload Size >= 512. It happens with Aardvark PCIe controller (tested on Turris MOX) and also with DesignWare controller (armada8k, tested on CN9130-CRB): ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata1.00: ATA-9: WDC WD40EFRX-68WT0N0, 80.00A80, max UDMA/133 ata1.00: 7814037168 sectors, multi 0: LBA48 NCQ (depth 32), AA ERROR: Unhandled External Abort received on 0x80000000 at EL3! ERROR: exception reason=1 syndrome=0x92000210 PANIC at PC : 0x00000000040273bc Limiting Max Payload Size to 256 bytes solves this problem. On Turris MOX this problem first appeared when the pci-aardvark controller started using the pci-emul-bridge API, in commit 8a3ebd8de328 ("PCI: aardvark: Implement emulated root PCI bridge config space"). On armada8k this was always a problem because it has HW root bridge.

[PATCH] f2fs: remove broken support for allocating DIO writes

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Currently, non-overwrite DIO writes are fundamentally unsafe on f2fs as they require preallocating blocks, but f2fs doesn't support unwritten blocks and therefore has to preallocate the blocks as regular blocks. f2fs has no way to reliably roll back such preallocations, so as a result, f2fs will leak uninitialized blocks to users if a DIO write doesn't fully complete. This can be easily reproduced by issuing a DIO write that will fail due to misalignment, e.g.: rm -f file truncate -s 1000000 file dd if=/dev/zero bs=999999 oflag=direct conv=notrunc of=file od -tx1 file # shows uninitialized disk blocks Until a proper design for non-overwrite DIO writes on f2fs can be designed and implemented, remove support for them and make them fall back to buffered I/O. This is what other filesystems that don't support unwritten blocks, e.g. ext2, also do, at least for non-extending DIO writes. However, f2fs can't do extending DIO writes either, as f2fs appears to have no mechanism for guaranteeing that leftover allocated blocks past EOF will get truncated. (f2fs does have an orphan list, but it's only used for deleting inodes, not truncating them.) This patch doesn't attempt to remove the F2FS_GET_BLOCK_{DIO,PRE_DIO} cases in f2fs_map_blocks(); that can be cleaned up later.
