[PATCH v4] tpm: ibmvtpm: retry on H_CLOSED in tpm_ibmvtpm_send()

by George Wilson

tpm_ibmvtpm_send() can fail during PowerVM Live Partition Mobility resume with an H_CLOSED return from ibmvtpm_send_crq(). The PAPR says, 'The "partner partition suspended" transport event disables the associated CRQ such that any H_SEND_CRQ hcall() to the associated CRQ returns H_Closed until the CRQ has been explicitly enabled using the H_ENABLE_CRQ hcall.' This patch adds a check in tpm_ibmvtpm_send() for an H_CLOSED return from ibmvtpm_send_crq() and in that case calls tpm_ibmvtpm_resume() and retries the ibmvtpm_send_crq() once.

[PATCH v6 10/16] kernel/kcmp.c: Use new infrastructure to fix deadlocks in execve

by Bernd Edlinger

This changes kcmp_epoll_target to use the new exec_update_mutex instead of cred_guard_mutex. This should be safe, as the credentials are only used for reading, and furthermore ->mm and ->sighand are updated on execve, but only under the new exec_update_mutex.

[PATCH v6 14/16] pidfd: Use new infrastructure to fix deadlocks in execve

by Bernd Edlinger

This changes __pidfd_fget to use the new exec_update_mutex instead of cred_guard_mutex. This should be safe, as the credentials do not change before exec_update_mutex is locked. Therefore whatever file access is possible with holding the cred_guard_mutex here is also possbile with the exec_update_mutex.

4.19 LTS high /proc/diskstats io_ticks

by Rantala, Tommi T. (Nokia - FI/Espoo)

Hi, Tools like sar and iostat are reporting abnormally high %util with 4.19.y running in VM (the disk is almost idle): $ sar -dp Linux 4.19.107-1.x86_64 03/25/20 _x86_64_ (6 CPU) 00:00:00 DEV tps ... %util 00:10:00 vda 0.55 ... 98.07 ... 10:00:00 vda 0.44 ... 99.74 Average: vda 0.48 ... 98.98 The numbers look reasonable for the partition: # iostat -x -p ALL 1 1 Linux 4.19.107-1.x86_64 03/25/20 _x86_64_ (6 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 10.51 0.00 8.58 0.05 0.11 80.75 Device r/s ... %util vda 0.02 ... 98.25 vda1 0.01 ... 0.09 Lots of io_ticks in /proc/diskstats: # cat /proc/uptime 45787.03 229321.29 # grep vda /proc/diskstats 253 0 vda 760 0 38498 731 28165 43212 1462928 157514 0 44690263 44812032 0 0 0 0 253 1 vda1 350 0 19074 293 26169 43212 1462912 154931 0 41560 150998 0 0 0 0 Other people are apparently seeing this too with 4.19: https://kudzia.eu/b/2019/09/iostat-x-1-reporting-100-utilization-of-nearly-… I also see this only in 4.19.y and bisected to this (based on the Fixes tag, this should have been taken to 4.14 too...): commit 6131837b1de66116459ef4413e26fdbc70d066dc Author: Omar Sandoval <osandov(a)fb.com> Date: Thu Apr 26 00:21:58 2018 -0700 blk-mq: count allocated but not started requests in iostats inflight In the legacy block case, we increment the counter right after we allocate the request, not when the driver handles it. In both the legacy and blk-mq cases, part_inc_in_flight() is called from blk_account_io_start() right after we've allocated the request. blk-mq only considers requests started requests as inflight, but this is inconsistent with the legacy definition and the intention in the code. This removes the started condition and instead counts all allocated requests.

Before the commit, part_round_stats() would only update part->stamp when called after request allocation. Any thoughts how to best fix this in 4.19? I see the io_ticks accounting has been reworked in 5.0, do we need to backport those to 4.19, or any ill effects if this commit is reverted in 4.19? -Tommi
