Hi, I tried to run hugeshmat01 testcase, but it failed. This testcase failed in following systems. - RHEL5.5-ia64 - RHEL4.8-x86_64 - RHEL4.8-ia64
I used latest git:
ltp-dev-7c67a09a10268b5f9f503e0254f1f0f9f5ac2b69.tar.gz
This testcase failed also in previous gits.
RHEL5.5-ia64 log:
------------
hugeshmat01 1 TPASS : conditions and functionality are correct
hugeshmat01 2 TFAIL : hugeshmat01 call failed - errno = 22 : Invalid
argument
hugeshmat01 3 TBROK : Remaining cases broken
------------
It is caused by "EINVAL" failure of shmat().
---(hugeshmat01.c)---------
[...]
for (i=0; i<TST_TOTAL; i++) {
/*
* Use TEST macro to make the call
*/
errno = 0;
addr = shmat(*(TC[i].shmid), (void *)(TC[i].addr),
TC[i].flags);
[...]
------------
In second loop (i=1), arguments of shemat() are followings:
shmat(id, 0x10000000eee, SHM_RND)
This test expects that the return value of shmat() is rounded down to
a multiple of SHMLBA.
But shmat() failed in some systems.
I deduced that "0x10000000eee" address may be outside of hugepages area.
So I used the return value of first loop's shmat() instead of fixed
address ("0x10000000eee").
And the test succeeded.
