[LTP] [RFC PATCH 3/9] syscalls/ipc: Rewrite msgctl01 + merge msgctl06
Cyril Hrubis
chrubis@suse.cz
Tue Jun 12 17:46:25 CEST 2018
Rewrite msgctl01 to be much more strict, now we assert all fields of the
buffer we get from IPC_STAT.
This also removes msgctl06 that was testing the very same IPC_STAT
command but checked different subset of the msqid_ds buffer.

/*
- * NAME
- * msgctl01.c
- *
- * DESCRIPTION
- * msgctl01 - create a message queue, then issue the IPC_STAT command
- * and RMID commands to test the functionality
- *
- * ALGORITHM
- * create a message queue
- * loop if that option was specified
- * call msgctl() with the IPC_STAT command
- * check the return code
- * if failure, issue a FAIL message and break remaining tests
- * otherwise,
- * if doing functionality testing
- * if the max number of bytes on the queue is > 0,
- * issue a PASS message
- * otherwise
- * issue a FAIL message
- * else issue a PASS message
- * call cleanup
- *
- * USAGE: <for command-line>
- * msgctl01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- * where, -c n : Run n copies concurrently.
- * -f : Turn off functionality Testing.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * HISTORY
- * 03/2001 - Written by Wayne Boyer
- *
- * RESTRICTIONS
- * none
+ * Test that IPC_STAT command succeeds and the the buffer is filled with
+ * correct data.
