| | | | | | | | | privilege attempts to toggle SF_SETTABLE flags. - Use the '^' operator in the SF_SNAPSHOT anti-toggling check. Flags are now stored to ip->i_flags in one place after all checks. Submitted by: bde
* sem_open: Make sure to fail an O_CREAT|O_EXCL open, even if that semaphorejilles2012-04-091-4/+10
| | | | | | | | | | | | is already open in this process. If the named semaphore is already open, sem_open() only increments a reference count and did not take the flags into account (which otherwise happens by passing them to open()). Add an extra check for O_CREAT|O_EXCL. PR: kern/166706 Reviewed by: davidxu MFC after: 10 days
