The application changes the group ID of the semaphore and tries to use it after changing its own group ID. The only problem is that the semaphore's permissions are not being changed. I am not much of a kernel hacker, but I added a printf() to linux_semctl() in case LINUX_IPC_SET to see what it was getting. It appears that it received a 0 for GID and UID. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
