[LTP] [PATCH v1 0/2] Refactor getegid testing suite

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

The getegid testing suite has been refactored using new LTP API, optimising the
code by adding some other checks.

[LTP] [PATCH v1 1/2] Refactor getegid01 using new LTP API

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

This new version also verifies that getegid() effectively returns the
right effective group ID by looking at /proc/self/status information.

Hint: You can use assignment suppresion '*' in order to get rid of the
      dummy st_gid variable.

And this does not work at all.

The GID16_CHECK() is for the case where we have GID that is 32bit and we
want to check if the value fits into 16bit. In this case we get 16bit
value from the sycall, so the check will always be true.

Also the check only returns value, which we ingore here, so this isn't
doing anything at all.

What we need to do instead is to check the gid from /proc/ that is 32bit
if it fits into 16bit (in the case of the 16bit syscall) and skip the
comparsion below.

> +	TST_EXP_EQ_LI(gid, st_egid);

So the code here should really do:

	if (GID16_CHECK(st_egid))
		TST_EXP_EQ_LI(gid, st_egid);
	else
		tst_res(TPASS, "getgid() passed");

Which skips the check on 16bit syscall in the case that the GID
overflows 16bit, however we still have to report at least single TPASS
otherwise the test will be failed by the test library.

Mmmh, this would make sense if GID16_CHECK only checked for 16bit 
compatibility, because at the moment it's way different:


#define GID16_CHECK(gid, sys_name, cleanup) \
if (!GID_SIZE_CHECK(gid)) { \
     tst_brkm(TBROK, cleanup, \
         "gid %d of %s is too large for testing 16-bit version " \
         "of %s()", gid, #gid, #sys_name); \
}

Am I missing something?

It seems that I confused GID16_CHECK with GID_SIZE_CHECK(), so it should
have been:

	if (GID_SIZE_CHECK(st_egid))

SAFE_FILE_LINES_SCANF("/proc/self/status", "Gid: %*d %d", &st_egid); works for me.

Ok, that perfectly works now.

Waiting for getegid02 review, then I will modify code and send it with 
the patch set.

Re: [LTP] [PATCH v1 2/2] Refactor getegid02 using new LTP API

[Andrea Cervesato via ltp]

Hi!

I think you can push both getegid01 and getegid02 together, as Cyril 
mentioned in the getegid01 review.
Sorry, it was indeed better to create a patch set for this.

Thanks!
Andrea Cervesato
