* inet: request sock should init IPv6/IPv4 addressesEric Dumazet2015-03-195-10/+15
| | | | | | | | In order to be able to use sk_ehashfn() for request socks, we need to initialize their IPv6/IPv4 addresses. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* inet: add IPv6 support to sk_ehashfn()Eric Dumazet2015-03-197-45/+45
| | | | | | | | | | | | | | | | Intent is to converge IPv4 & IPv6 inet_hash functions to factorize code. IPv4 sockets initialize sk_rcv_saddr and sk_v6_daddr in this patch, thanks to new sk_daddr_set() and sk_rcv_saddr_set() helpers. __inet6_hash can now use sk_ehashfn() instead of a private inet6_sk_ehashfn() and will simply use __inet_hash() in a following patch.

| * tipc: fix netns refcnt leakYing Xue2015-03-183-92/+39Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the TIPC module is loaded, we launch a topology server in kernel space, which in its turn is creating TIPC sockets for communication with topology server users. Because both the socket's creator and provider reside in the same module, it is necessary that the TIPC module's reference count remains zero after the server is started and the socket created; otherwise it becomes impossible to perform "rmmod" even on an idle module. Currently, we achieve this by defining a separate "tipc_proto_kern" protocol struct, that is used only for kernel space socket allocations. This structure has the "owner" field set to NULL, which restricts the module reference count from being be bumped when sk_alloc() for local sockets is called. Furthermore, we have defined three kernel-specific functions, tipc_sock_create_local(), tipc_sock_release_local() and tipc_sock_accept_local(), to avoid the module counter being modified when module local sockets are created or deleted. This has worked well until we introduced name space support. However, after name space support was introduced, we have observed that a reference count leak occurs, because the netns counter is not decremented in tipc_sock_delete_local(). This commit remedies this problem. But instead of just modifying tipc_sock_delete_local(), we eliminate the whole parallel socket handling infrastructure, and start using the regular sk_create_kern(), kernel_accept() and sk_release_kernel() calls. Since those functions manipulate the module counter, we must now compensate for that by explicitly decrementing the counter after module local sockets are created, and increment it just before calling sk_release_kernel().

I included two TCP changes in this patch series. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * tcp: uninline tcp_oow_rate_limited()Eric Dumazet2015-03-172-30/+32
| | | | | | | | | | | | | | | | | | tcp_oow_rate_limited() is hardly used in fast path, there is no point inlining it. Signed-of-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * tcp: move tcp_openreq_init() to tcp_input.cEric Dumazet2015-03-172-25/+25
| | | | | | | | | | | | | | | | This big helper is called once from tcp_conn_request(), there is no point having it in an include. Compiler will inline it anyway. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * inet: move ir_mark to fill a holeEric Dumazet2015-03-171-6/+5Star
| | | | | | | | | | | | | | | | | | | | | | On 64bit arches, we can save 8 bytes in inet_request_sock by moving ir_mark to fill a hole. While we are at it, inet_request_mark() can get a const qualifier for listener socket. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * netfilter: xt_socket: prepare for TCP_NEW_SYN_RECV supportEric Dumazet2015-03-171-12/+22
| | | | | | | | | | | | | | | | | | | | TCP request socks soon will be visible in ehash table. xt_socket will be able to match them, but first we need to make sure to not consider them as full sockets.

| * netfilter: tproxy: prepare TCP_NEW_SYN_RECV supportEric Dumazet2015-03-171-6/+12
| | | | | | | | | | | | | | TCP request socks soon will be visible in ehash table. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * netfilter: use sk_fullsock() helperEric Dumazet2015-03-175-6/+6
|/ | | | | | | | | Upcoming request sockets have TCP_NEW_SYN_RECV state and should be special cased a bit like TCP_TIME_WAIT sockets. Signed-off-by; Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bpf: allow BPF programs access 'protocol' and 'vlan_tci' fieldsAlexei Starovoitov2015-03-173-22/+62
| | | | | | | | | | | | | as a follow on to patch 70006af95515 ("bpf: allow eBPF access skb fields") this patch allows 'protocol' and 'vlan_tci' fields to be accessible from extended BPF programs. The usage of 'protocol', 'vlan_present' and 'vlan_tci' fields is the same as corresponding SKF_AD_PROTOCOL, SKF_AD_VLAN_TAG_PRESENT and SKF_AD_VLAN_TAG accesses in classic BPF.
