Description of problem: Somehow the handling of FUTEX_CMP_REQUEUE_PI crept into strace. That operation is not supported in the upstream kernel. And worse: the opcode number is used for something else. The newer operations FUTEX_WAIT_BITSET and FUTEX_WAKE_BITSET collide with the incorrect FUTEX_CMP_REQUEUE_PI handling. I'm attaching a patch to correct the problem. Version-Release number of selected component (if applicable): strace-4.5.16-5.fc9 How reproducible: always Steps to Reproduce: 1.run code using FUTEX_WAIT_BITSET under strace 2. 3. Actual results: shown as FUTEX_CMP_REQUEUE_PI operations Expected results: shown as FUTEX_WAIT_BITSET operation Additional info:
Created attachment 306847 [details] Add support for the bitset operations, removing CMP_REQUEUE_PI
Created attachment 306851 [details] Same patch, but don't add printing of parameter for all other operations Little extra change slipped into the last patch.
Patch seems to be in upstream strace cvs already.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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
The strace in F11 is not updated.
Fixed in 4.5.19-1.
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
