We are seeing infrequent failures in the LTP test gettimeofday02, possibly a couple of times a month in our automated testing. <<<test_start>>> tag=gettimeofday02 stime=1205421336 cmdline="gettimeofday02" contacts="" analysis=exit initiation_status="ok" <<<test_output>>> gettimeofday02 0 INFO : checking if gettimeofday is monotonous, takes 30s gettimeofday02 1 FAIL : Time is going backwards (old 1205421341.12818 vs new 1205421341.12812! <<<execution_status>>> duration=5 termination_type=exited termination_id=1 corefile=no cutime=87 cstime=391 <<<test_end>>> This was fixed upstream with http://hg.uk.xensource.com/linux-2.6.18-xen.hg?cs=87bb8705768 which applies cleanly to the 2.6.9-67.0.7.EL tree.
Ian, thanks for the bz! this was patched in rhel5; why it wasn't cloned for rhel4, I don't know. the rhel5 bz was 245761. I ran Rik's clocktest program from 245761 (comment #22), and it failed *immediately*. I will file a patch for rhel4 asap, ask for exception, and ask for it to be included in 4.6 z-stream.
Please us URLs which are visible from the external internet when posting patches! http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev/87bb8705768 is the xenbits URL for the above changeset.
Don: Unfortunately I don't have permission to access 245761 ("Access to some bugs is restricted due to embargoed security issues or respect for customer and partner information which must remain confidential.") or comment #22 therein. Stephen: Sorry, my fingers are hard coded for the internal (i.e. local) mirror. I do it nearly every time :-(
Justification for exception to 4.7: see bz 245761; same problems, same fix, (rhel4.6-specific patch above), same biz justification, same test program (comment #22 from bz 245761), use test program to verify fix. Please review exception, set appropriate flags. - Don ps -- if this is accepted/exceptioned into 4.7, I would strongly recommend it as a candidate for 4.6 z-stream.
Ian, I will post the 245761 attachement to this bz, so you can grab the test program for your future reference/use. as for the auto-bad-http-link ... i'm use to it... i sub'd "xenbits" for 'hg.uk' as automagically as you use it to post .... old dog, new trick! ;-) - Don
