2e60314c2809408f999c080cf3980dc5a5b5ce96 - Merge branch 'process-connector-bug-fixes-and-enhancements'

Sun, 23 Jul 2023 12:34:22 +0200

Merge branch 'process-connector-bug-fixes-and-enhancements'Anjali Kulkarni says:====================Process connector bug fixes & enhancementsOracle DB is trying to solve a performance overhead problem it has beenfacing for the past 10 years and using this patch series, we can fix thisissue.Oracle DB runs on a large scale with 100000s of short lived processes,starting up and exiting quickly. A process monitoring DB daemon whichtracks and cleans up after processes that have died without a proper exitneeds notifications only when a process died with a non-zero exit code(which should be rare).Due to the pmon architecture, which is distributed, each process isindependent and has minimal interaction with pmon. Hence fd basedsolutions to track a process's spawning and exit cannot be used. Pmonneeds to detect the abnormal death of a process so it can cleanup after.Currently it resorts to checking /proc every few seconds. Other methodswe tried like using system call to reduce the above overhead were notaccepted upstream.With this change, we add event based filtering to proc connector moduleso that DB can only listen to the events it is interested in. A newevent type PROC_EVENT_NONZERO_EXIT is added, which is only sent by kernelto a listening application when any process exiting has a non-zero exitstatus.This change will give Oracle DB substantial performance savings - it takes50ms to scan about 8K PIDs in /proc, about 500ms for 100K PIDs. DB doesthis check every 3 secs, so over an hour we save 10secs for 100K PIDs.With this, a client can register to listen for only exit or fork or a mix orall of the events. This greatly enhances performance - currently, weneed to listen to all events, and there are 9 different types of events.For eg. handling 3 types of events - 8K-forks + 8K-exits + 8K-execs takes200ms, whereas handling 2 types - 8K-forks + 8K-exits takes about 150ms,and handling just one type - 8K exits takes about 70ms.Measuring the time using pidfds for monitoring 8K process exits took 4times longer - 200ms, as compared to 70ms using only exit notificationsof proc connector. Hence, we cannot use pidfd for our use case.This kind of a new event could also be useful to other applications likeGoogle's lmkd daemon, which needs a killed process's exit notification.This patch series is organized as follows -Patch 1 : Needed for patch 3 to work.Patch 2 : Needed for patch 3 to work.Patch 3 : Fixes some bugs in proc connector, details in the patch.Patch 4 : Adds event based filtering for performance enhancements.Patch 5 : Allow non-root users access to proc connector events.Patch 6 : Selftest code for proc connector.v9->v10 changes:- Rebased to net-next, re-compiled and re-tested.v8->v9 changes:- Added sha1 ("title") of reversed patch as suggested by Eric Dumazet.v7->v8 changes:- Fixed an issue pointed by Liam Howlett in v7.v6->v7 changes:- Incorporated Liam Howlett's comments on v6- Incorporated Kalesh Anakkur Purayil's commentsv5->v6 changes:- Incorporated Liam Howlett's comments- Removed FILTER define from proc_filter.c and added a "-f" run-time option to run new filter code.- Made proc_filter.c a selftest in tools/testing/selftests/connectorv4->v5 changes:- Change the cover letter- Fix a small issue in proc_filter.cv3->v4 changes:- Fix comments by Jakub Kicinski to incorporate root access changes within bind call of connectorv2->v3 changes:- Fix comments by Jakub Kicinski to separate netlink (patch 2) (after layering) from connector fixes (patch 3).- Minor fixes suggested by Jakub.- Add new multicast group level permissions check at netlink layer. Split this into netlink & connector layers (patches 6 & 7)v1->v2 changes:- Fix comments by Jakub Kicinski to keep layering within netlink and update kdocs.- Move non-root users access patch last in series so remaining patches can go in first.v->v1 changes:- Changed commit log in patch 4 as suggested by Christian Brauner- Changed patch 4 to make more fine grained access to non-root users- Fixed warning in cn_proc.c, Reported-by: kernel test robot - Fixed some existing warnings in cn_proc.c====================Signed-off-by: David S.
