Hi all, while running the openposix testsuite I saw testcase timer_create/9-1.c failing. This testcase tests whether timers are disarmed when a process calls exec, as described in e.g. http://www.opengroup.org/onlinepubs/009695399/functions/timer_create.html. The attached one-liner patch (+ one line comment) fixes this issue. I did the diff against 2.6.12.1, but the fix is pretty much the same for every other 2.6.x kernel I had a look at. I don't think this patch breaks anything, as relying on this (undocumented) behaviour would imho be bad style. So tell me what you think, and if you have some pointers to interesting discussions about Linux and POSIX compliance then I would like to read that as well. mfg Gernot --- linux-2.6.12.1-orig/fs/exec.c 2005-06-29 14:29:31.069738264 +0200 +++ linux-2.6.12.1/fs/exec.c 2005-06-29 14:34:46.034856288 +0200 @@ -1200,6 +1200,10 @@ acct_update_integrals(current); update_mem_hiwater(current); kfree(bprm); + + /* delete old itimers */ + exit_itimers(current->signal); + return retval; } | ||||||||||||
