netlink: invert error code in netlink_set_err()
The callers of netlink_set_err() currently pass a negative value as parameter for the error code. However, sk->sk_err wants a positive error value. Without this patch, skb_recv_datagram() called by netlink_recvmsg() may return a positive value to report an error. Another choice to fix this is to change callers to pass a positive error value, but this seems a bit inconsistent and error prone to me. Indeed, the callers of netlink_set_err() assumed that the (usual) negative value for error codes was fine before this patch :). This patch also includes some documentation in docbook format for netlink_set_err() to avoid this sort of confusion. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.
