[LTP] [PATCH v6] Testing statx syscall
Vaishnavi D
vaishnavi.d@zilogic.com
Wed Aug 22 12:57:47 CEST 2018
From: vaishnavid <vaishnavi.d@zilogic.com>
* statx01.c: This file will check metadata of files like uid, gid,
size, blocks, mode for normal file(1) and rdev_major, rdev_minor
number for device file(2)
* statx02.c: This file will check flag like AT_EMPTY_PATH,
AT_SYMLINK_NOFOLLOW
* AT_EMPTY_PATH: If pathname is an empty string,
operate on the file referred to by dirfd.
* AT_SYMLINK_NOFOLLOW:If pathname is a symbolic link, do not
dereference it: instead return information about the link itself.
* stat03.c: This file will check error code(errno) by providing
required input in statx argument syscall. The following errno are
checked: EBADF, EBADF, ENAMETOOLONG, ENOENT, ENOTDIR, EFAULT.
* statx04.c: This file will check attribute flag by defining flag
to that directory and checks another directory with no flags.
Changes from V5 to V6:
* Made changes in the m4 file and LTP_CHECK_STATX added to configure.ac
* Replaced arch-specific printf format with general one.
* Added ifndef cases for structs in stat.h.
