net/unix: support SCM_SECURITY for stream sockets

2015-06-11T05:49:20+00:00

SCM_SECURITY was originally only implemented for datagram sockets, not for stream sockets. However, SCM_CREDENTIALS is supported on Unix stream sockets. For consistency, implement Unix stream support for SCM_SECURITY as well. Also clean up the existing code and get rid of the superfluous UNIXSID macro. Motivated by https://bugzilla.redhat.com/show_bug.cgi?id=1224211, where systemd was using SCM_CREDENTIALS and assumed wrongly that SCM_SECURITY was also supported on Unix stream sockets.

Conflicts: drivers/net/phy/amd-xgbe-phy.c drivers/net/wireless/iwlwifi/Kconfig include/net/mac80211.h iwlwifi/Kconfig and mac80211.h were both trivial overlapping changes. The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and the bug fix that happened on the 'net' side is already integrated into the rest of the amd-xgbe driver. Signed-off-by: David S.

net: af_unix: implement splice for stream af_unix sockets

2015-05-25T04:06:59+00:00

unix_stream_recvmsg is refactored to unix_stream_read_generic in this patch and enhanced to deal with pipe splicing. The refactoring is inneglible, we mostly have to deal with a non-existing struct msghdr argument. Signed-off-by: Hannes Frederic Sowa Signed-off-by: David S. Miller

net: af_unix: implement stream sendpage support

2015-05-25T04:06:58+00:00

This patch implements sendpage support for AF_UNIX SOCK_STREAM sockets. This is also required for a complete splice implementation. The implementation is a bit tricky because we append to already existing skbs and so have to hold unix_sk->readlock to protect the reading side from either advancing UNIXCB.consumed or freeing the skb at the socket receive tail.

net: Pass kern from net_proto_family.create to sk_alloc

2015-05-11T14:50:17+00:00

In preparation for changing how struct net is refcounted on kernel sockets pass the knowledge that we are creating a kernel socket from sock_create_kern through to sk_alloc. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller
