netrom: fix info leak via msg_name in nr_recvmsg()

2013-05-01T16:46:02+00:00

[ Upstream commits 3ce5efad47b62c57a4f5c54248347085a750ce0e and c802d759623acbd6e1ee9fbdabae89159a513913 ] In case msg_name is set the sockaddr info gets filled out, as requested, but the code fails to initialize the padding bytes of struct sockaddr_ax25 inserted by the compiler for alignment. Also the sax25_ndigis member does not get assigned, leaking four more bytes. Both issues lead to the fact that the code will leak uninitialized kernel stack bytes in net/socket.c. Fix both issues by initializing the memory with memset(0). Signed-off-by: Mathias Krause Cc: Ralf Baechle Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

net: Convert all sysctl registrations to register_net_sysctl

2012-04-21T01:22:30+00:00

This results in code with less boiler plate that is a bit easier to read. Additionally stops us from using compatibility code in the sysctl core, hastening the day when the compatibility code can be removed. Signed-off-by: Eric W. Biederman Acked-by: Pavel Emelyanov Signed-off-by: David S. Miller

net: Move all of the network sysctls without a namespace into init_net.

2012-04-21T01:21:17+00:00

This makes it clearer which sysctls are relative to your current network namespace. This makes it a little less error prone by not exposing sysctls for the initial network namespace in other namespaces. This is the same way we handle all of our other network interfaces to userspace and I can't honestly remember why we didn't do this for sysctls right from the start. Signed-off-by: Eric W.

net: cleanup unsigned to unsigned int

NET: NETROM: Cleanup argument SIOCADDRT ioctl argument checking.

2011-11-29T05:23:13+00:00

nr_route.ndigis is unsigned int so the nr_route.ndigis < 0 expression is never true and can be dropped. Doing the nr_ax25_dev_get call later allows the nr_route.ndigis test to bail out without having to dev_put. Signed-off-by: Ralf Baechle Cc: Thomas Osterried Signed-off-by: David S. Miller
