http://bugzilla.novell.com/show_bug.cgi?id=546559 Summary: kernel notify event DN_DELETE wrongly handled Classification: openSUSE Product: openSUSE 11.2 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: agruen@novell.com ReportedBy: ms@novell.com QAContact: qa@suse.de Found By: --- When using the kernel notify system to detect create and delete events the delete event produces two signals: "delete" but followed by a wrong "create" event How to reproduce: code example ---snip--- #define _GNU_SOURCE #include #include #include #include #include #include #include void handleNotifyEvent ( int, siginfo_t* , void* ); int main (void) { int n=0; struct sigaction action; sigset_t block_set; action.sa_sigaction = handleNotifyEvent; sigemptyset (&action.sa_mask); action.sa_flags = SA_SIGINFO; sigaction (SIGRTMIN + 0 , &action , NULL); sigaction (SIGRTMIN + 1 , &action , NULL); sigemptyset (&block_set); sigaddset (&block_set,SIGIO); for (n=0;n<2;n++) { sigaddset (&block_set,SIGRTMIN + n); } sigprocmask(SIG_BLOCK, &block_set,0); for (n=0;n<2;n++) { int fd = open ("/mnt/", O_RDONLY); if (fd == -1) { return 1; } fcntl (fd, F_SETSIG, SIGRTMIN + n); long flags = 0; switch (n) { case 0: flags = DN_MULTISHOT | DN_CREATE; break; case 1: flags = DN_MULTISHOT | DN_DELETE; break; default: break; } if (fcntl (fd,F_NOTIFY, flags) == -1) { return 1; } } sigprocmask(SIG_UNBLOCK, &block_set,0); printf ("entering event loop\n"); while (1) { pause(); } } void handleNotifyEvent ( int s, siginfo_t* si , void* p) { if (s == SIGRTMIN) { printf ("Create... %d\n",si->si_fd); } else { printf ("Delete... %d\n",si->si_fd); } } ---snap--- Thanks -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
