[PATCH 1/2] tests: Additional IPC checks
|
From: Eugene S. <ev...@gm...> - 2016-09-07 12:41:12
|
* tests/ipc_msg.c: Additional msgget (parameter format), msgctl
(parameter format, decoding of struct msqid_ds in IPC_SET/IPC_STAT
commands) checks.
* tests/ipc_sem.c: Additional semget, semctl checks.
* tests/ipc_shm.c: Additional shmctl checks.
* tests/semop.c: Additional semop checks. Added checks for semtimedop.
* tests/semop.test: Add explicit -e parameter in order to trace both
semop and semtimedop.
* tests/shmxt.c: Additional shmat/shmdt tests.
