[NETNS]: Add netns refcnt debug for kernel sockets.

2008-04-16T08:59:46+00:00

Protocol control sockets and netlink kernel sockets should not prevent the namespace stop request. They are initialized and disposed in a special way by sk_change_net/sk_release_kernel. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

socket: sk_filter deinline

2008-04-10T08:43:09+00:00

The sk_filter function is too big to be inlined. This saves 2296 bytes of text on allyesconfig. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[SOCK][NETNS]: Add a struct net argument to sock_prot_inuse_add and _get.

2008-04-01T02:41:46+00:00

This counter is about to become per-proto-and-per-net, so we'll need two arguments to determine which cell in this "table" to work with. All the places, but proc already pass proper net to it - proc will be tuned a bit later. Some indentation with spaces in proc files is done to keep the file coding style consistent.

[SOCK]: Drop inuse pcounter from struct proto (v2).

2008-03-28T23:39:33+00:00

An uppercut - do not use the pcounter on struct proto. Signed-off-by: Pavel Emelyanov Acked-by: Eric Dumazet Signed-off-by: David S. Miller

[SOCK]: Drop per-proto inuse init and fre functions (v2).

2008-03-28T23:39:10+00:00

Constructive part of the set is finished here. We have to remove the pcounter, so start with its init and free functions. Signed-off-by: Pavel Emelyanov Acked-by: Eric Dumazet Signed-off-by: David S. Miller

[SOCK]: Introduce a percpu inuse counters array (v2).

2008-03-28T23:38:43+00:00

And redirect sock_prot_inuse_add and _get to use one. As far as the dereferences are concerned. Before the patch we made 1 dereference to proto->inuse.add call, the call itself and then called the __get_cpu_var() on a static variable. After the patch we make a direct call, then one dereference to proto->inuse_idx and then the same __get_cpu_var() on a still static variable. So this patch doesn't seem to produce performance penalty on SMP. This is not per-net yet, but I will deliberately make NET_NS=y case separated from NET_NS=n one, since it'll cost us one-or-two more dereferences to get the struct net and the inuse counter.

[SOCK]: Enumerate struct proto-s to facilitate percpu inuse accounting (v2).

2008-03-28T23:38:17+00:00

The inuse counters are going to become a per-cpu array. Introduce an index for this array on the struct proto. To handle the case of proto register-unregister-register loop the bitmap is used. All its bits manipulations are protected with proto_list_lock and a sanity check for the bitmap being exhausted is also added.

[NETNS]: Compilation warnings under CONFIG_NET_NS.

2008-03-26T07:48:17+00:00

Recent commits from YOSHIFUJI Hideaki have been introduced a several compilation warnings 'assignment discards qualifiers from pointer target type' due to extra const modifier in the inline call parameters of {dev|sock|twsk}_net_set. Drop it. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55+00:00

Introduce per-sock inlines: sock_net(), sock_net_set() and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki

[RAW]: Add raw_hashinfo member on struct proto.

2008-03-22T23:56:51+00:00

Sorry for the patch sequence confusion :| but I found that the similar thing can be done for raw sockets easily too late. Expand the proto.h union with the raw_hashinfo member and use it in raw_prot and rawv6_prot. This allows to drop the protocol specific versions of hash and unhash callbacks.
