+Subject: [PATCH] net: enhance getsockopt decoding
+
+When getsockopt syscall fails the kernel sometimes updates the optlen
+argument, for example, NETLINK_LIST_MEMBERSHIPS updates it even if
+optval is not writable.
+
+* src/net.c (SYS_FUNC(getsockopt)): Try to fetch and print optlen
+argument on exiting syscall regardless of getsockopt exit status.

+Subject: [PATCH] tests: update sockopt-sol_netlink test
+
+Update sockopt-sol_netlink test that started to fail, likely
+due to recent linux kernel commit f4e4534850a9 ("net/netlink: fix
+NETLINK_LIST_MEMBERSHIPS length report").
+
+* tests/sockopt-sol_netlink.c (main): Always print changing optlen value
+on exiting syscall.
