[Bug libc/30270] syslog: openlog with NDELAY, but seccomp still requires openat(2) and lseek(2)?

--- Comment #3 from Steffen Nurpmeso <steffen at sdaoden dot eu> ---
I am explicitly doing "%.950s" to avoid taking the alloc path.
'Would have hoped NDELAY gets over some..  i do have

        /* syslog (plus reopen) */\
        a_SEND,\
a_ALLOW(SYS_openat),\
a_ALLOW(SYS_lseek),\
        a_ALLOW(SYS_socket),\
        a_ALLOW(SYS_connect),\
        a_ALLOW(SYS_getpid),\

unfortunately (i use LOG_PID).
(I am currently wondering whether i can really do enable seccomp(2) for this by
default, sitting on a moving black box.)

Patch 4 is (CRUX Linux, core collection)
