When we executing the LTP test case found that gethostbyname_r syscall is not returning ERANGE when invalid buffer length is passed. As per the man page "https://linux.die.net/man/3/gethostbyname_r" it should return...

[Tests] getgroups system call causing SIGILL when size is “-1”

This test case tests “getgroups01” system call behavior by passing different parameter values. Below are the test cases. Sub-Test-Case-1: Check to see if getgroups(-1, gidset) fails and sets errno to...
