[Qemu-devel] [PATCH v2 04/16] linux-user: support SO_PASSSEC setsockopt option

[Paul Burton <paul@archlinuxmips.org>]

Translate the SO_PASSSEC option to setsockopt to the host value &
perform the syscall as expected, allowing use of the option by target
programs.

Signed-off-by: Paul Burton <paul@archlinuxmips.org>
