Hi! I've tried to post PR, but it seems it got lost somewhere. I just wonder whether there was some change in shmget behavior in current. Look at this patch to src/sys-cur/tools/regression/sysvshm/shmtest.c --- shmtest_old.c Tue Nov 28 09:59:55 2006 +++ shmtest.c Tue Nov 28 09:58:39 2006 @@ -126,6 +126,9 @@ if ((sender_shmid = shmget(shmkey, pgsize, IPC_CREAT | 0640)) == -1) err(1, "shmget"); + if ((sender_shmid = shmget(shmkey, pgsize, 0640)) == -1) + err(1, "shmget"); + if (shmctl(sender_shmid, IPC_STAT, &s_ds) == -1) err(1, "shmctl IPC_STAT"); It failed with permission denied. Is that ok? Same code does not fail on STABLE nor Linux. The system is: i386 FreeBSD 7.0-CURRENT Relevant part of conf file: options SYSVSHM #SYSV-style shared memory options SYSVMSG #SYSV-style message queues options SYSVSEM #SYSV-style semaphores As I searched via cvsview, there were no suspicious changes in sysv ipc code recently, the only change is switch to priv(9) from suser(9). Thanks for clarification, Jarda Suchanekhome | help
