Subject: Re: pax-utils
pax-utils is primarily for PaX, so without this patch is losing a lot
of functionality, like pspax tool:
entropy# pspax -h
* List ELF/PaX information about running processes
Usage: pspax [options]
Options:
-a, --all * Show all processes
-e, --header * Print GNU_STACK/PT_LOAD markings
-i, --ipaddr * Print ipaddr info if supported
-p, --pid * Process ID/pid #
-u, --user * Process user/uid #
-g, --group * Process group/gid #
-n, --nx * Only display w^x processes
-w, --wx * Only display w|x processes
-W, --wide * Wide output display of cmdline
-v, --verbose * Be verbose about executable mappings
-C, --nocolor * Don't emit color in output
-B, --nobanner * Don't display the header
-h, --help * Print this help and exit
-V, --version * Print version and exit
