I guess that technically this should be (NGROUPS+1) * sizeof(GID_T) even
though in reality kernel will return error even before it attempts to
access the buffer.

tst_get_bad_addr() please.


Otherwise it looks good.

Hi Cyril

Hi!
There is a typo in the subject which got me confused for a while
s/getgroups/setgroups/


Sorry for my mistake

1.merge setgroups04 to setgroups03
2.use safe_macro macro

I guess that technically this should be (NGROUPS+1) * sizeof(GID_T) even
though in reality kernel will return error even before it attempts to
access the buffer.


Agree.




+       glist3 = sbrk(0);



tst_get_bad_addr() please.


Otherwise it looks good.



I will update it.

- *    DETAILED DESCRIPTION
- *	This is a Phase I test for the setgroups(2) system call.  It is intended
- *	to provide a limited exposure of the system call, for now.  It
- *	should/will be extended when full functional tests are written for
- *	setgroups(2).
- *
- * 	Setup:
- * 	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *
- * 	Test:
- *	 Loop if the proper options are given.
- * 	  Execute system call
- *	  Check return code, if system call failed (return=-1)
- *		Log the errno and Issue a FAIL message.
- *	  Otherwise, Issue a PASS message.
- *
- * 	Cleanup:
- * 	  Print errno log and/or timing stats if options given
- *
