screen_play.c: In function 'handle_save_playlist':
screen_play.c:119: warning: generating trampoline in object (requires executable stack)

hardened, some way to fix/avoid this, a part rewriting the code?
Comment 2 SpanKY gentoo-dev 2006-04-11 10:21:11 UTC 
prob not

my guess is there are nested functions ... just unnest them and mark the functions static
Comment 3 Diego Elio Pettenò (RETIRED) gentoo-dev 2006-04-18 11:27:10 UTC 
I would suggest UPSTREAM then or reassigning to hardened team, as I don't actually want to mess more with this than it's needed...
Comment 4 SpanKY gentoo-dev 2006-04-18 17:24:44 UTC 
it cant really be fixed without recoding:

handle_save_playlist(screen_t *screen, mpdclient_t *c, char *name)
{
    ...
    void pre_completion_cb(GCompletion *gcmp, gchar *line)
    {
        ...
        list = gcmp_list_from_path(c, "", NULL, GCMP_TYPE_PLAYLIST);
    }
    ...
    wrln_pre_completion_callback = pre_completion_cb;
    filename = screen_readln(screen->status_window.w ...)
    ...
}

Why was this closed upstream? The ebuild incorrectly assumes mmx.
Comment 7 solar (RETIRED) gentoo-dev 2006-04-21 04:57:14 UTC 
Sorry wrong I just commented on the wrong bug.
