lsattr,chattr: do not open e.g. device files unless asked directly; do not follow links
Add O_NOFOLLOW (and O_NOCTTY for good measure) to open calls like e2fsprogs does. In lsattr, when recursing, operate only on regular files, symlinks, and directories. (Otherwise, "lsattr /dev" can e.g. open a watchdog device... not good). At this time, looks like chattr/lsattr can't operate on symlink inodes - ioctls do not work on open(O_PATH | O_NOFOLLOW) fds. function old new delta lsattr_dir_proc 168 203 +35 change_attributes 410 408 -2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 35/-2) Total: 33 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
