Let's error out on syscalls that cannot be resolved or fail to resolve instead
of just warning users.

Seccomp fixup part 2

Be more strict about unrecognized actions. Previously the
parser would happily accept lines with typos like:

  kexec_load errrno 1

(note the extra 'r')
Signed-off-by: Wolfgang Bumiller <w.bumiller@proxmox.com>

Moving parse_config_v2 to use getline accidentally parsed
the wrong buffer. Since both _v1 and _v2 now use getline it
seems to be simpler to also use getline() for the first line
before entering the version specific parsers and pass along
the pointer and size so they can reuse them.

Fixes: 9c3798eb ("seccomp: parse_config_v2()")

This can happen when the 'errno' action can't parse its
supplied number.

seccomp: leak fixup

Fix an error case not free()ing the line forgotten during
the move from fgets() on a static buffer to using getline.

seccomp: cleanup

tree-wide: s/sigprocmask/pthread_sigmask()/g

sscanf() skips whitespace anyway so don't account for tabs in case the file
layout changes.
Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>

The behavior of sigprocmask() is unspecified in multi-threaded programs. Let's
use pthread_sigmask() instead.
