Subject: [PATCH net-next] ipv6: Fix inet6_csk_bind_conflict so it builds with user namespaces enabled
Date: Tue, 29 Jan 2013 04:16:18 -0800	[thread overview]
Message-ID: <871ud4chgt.fsf@xmission.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1301201542470.2060@pokey.mtv.corp.google.com> (Tom Herbert's message of "Sun, 20 Jan 2013 16:07:48 -0800 (PST)")


When attempting to build linux-next with user namespaces enabled I ran
into this fun build error.

  CC      net/ipv6/inet6_connection_sock.o
.../net/ipv6/inet6_connection_sock.c: In function ‘inet6_csk_bind_conflict’:
.../net/ipv6/inet6_connection_sock.c:37:12: error: incompatible types when initializing type ‘int’ using
 type ‘kuid_t’
.../net/ipv6/inet6_connection_sock.c:54:30: error: incompatible type for argument 1 of ‘uid_eq’
.../include/linux/uidgid.h:48:20: note: expected ‘kuid_t’ but argument is of type ‘int’
make[3]: *** [net/ipv6/inet6_connection_sock.o] Error 1
make[2]: *** [net/ipv6] Error 2
make[2]: *** Waiting for unfinished jobs....

Using kuid_t instead of int to hold the uid fixes this.
