Created attachment 327662 [details] patch attempting to fix problem Description of problem: During our IDS work it was noticed that mysql creates copious amounts of syscalls that return EINVAL. The cause is during SCHED_OTHER policy, the sched_priority value must be 0. Since the purpose of the call to pthread_setschedparam is to set the priority, we should noop the use of that function. How reproducible: always Steps to Reproduce: 1. add the following audit rule: -a always,exit -S sched_setscheduler -F exit=-EINVAL -k einval 2. reboot machine with mysql running 3. ausearch --start today -k einval Adding patch that should fix the problem.
I don't see any very good reason why I shouldn't close this NOTABUG. The code isn't causing anything bad to happen; moreover, the proposed patch doesn't appear to have any connection to the actual use of pthread_setschedparam --- it's called with SCHED_POLICY, not SCHED_OTHER.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This is fixed in F-11 ... how much do you care about prior branches?
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
Hmm ... not sure whether mysql has changed since 5.1.33 or whether the original patch failed to fix the problem at all, but this issue has definitely come back as of 5.1.52. It looks like we have to disable use of both pthread_setschedparam and pthread_setschedprio to suppress these calls.
