Re: Tracing Syscalls under Fedora 9

2008-06-27 Thread Roland McGrath
 So, it looks like a 2.6.25 i686 problem.

Indeed so.  Sorry about that, folks.  As I said at the time, the 2.6.25
rebase was quick and dirty and this regression slipped through.  It is
only the i386 kernel, not x86_64.  I'll get in fixed in Fedora soon.


Thanks,
Roland

 Hi,
 
 has the tracing of system calls changed in utrace between Fedora 8 and 9?
 
 My module works fine under Fedora 8, but under Fedora 9 the callbacks
 report_syscall_entry and report_syscall_exit seam not to be invoked
 any more.

If it helps at all, systemtap is seeing the same thing - system call
callbacks that got called under F8 aren't getting called under F9.

 For some reason the only way to trace the syscall is to trace also 
 UTRACE_EVENT(SIGNAL_TERM)
 or CORE.
 
 I added an empty report_signal function and now it works.

Martin told me by an E-mail message that the change proposed above solved
his problem. This is for the people on the ML concerned with the same
trouble.
