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:

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.

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. Signed-off-by:

With a was number of callsites sctp_add_cmd_sf wrapper bloats kernel by some amount. Due to unlikely tracking allyesconfig, with the initial result were around ~7kB (thus caught my attention) while a non-debug config produced only ~2.3kB effect. I (ij) proposed first a patch to uninline it but Vlad responded with a patch that removed the only sctp_add_cmd call which is wrapped by sctp_add_cmd_sf (I wasn't sure if I could do that). I did minor cleanup to Vlad's patch. Signed-off-by:

Based upon a lockdep report. Since ->poll() can be invoked from netpoll with interrupts disabled, we must not unconditionally enable interrupts in napi_complete(). Instead we must use local_irq_{save,restore}(). Noticed by Peter Zijlstra: <irqs disabled> netpoll_poll() poll_napi() spin_trylock(&napi->poll_lock) poll_one_napi() napi->poll() := sky2_poll() napi_complete() local_irq_disable() local_irq_enable() <--- *BUG* <irq> irq_exit() do_softirq() net_rx_action() spin_lock(&napi->poll_lock) <--- Deadlock! Because we still hold the lock.... Signed-off-by: -

ESP does not account for the IV size when calling pskb_may_pull() to ensure everything it accesses directly is within the linear part of a potential fragment. This results in a BUG() being triggered when the both the IPv4 and IPv6 ESP stack is fed with an skb where the first fragment ends between the end of the esp header and the end of the IV.

This patch tries to make dmesg logs between different runs easier to compare by * removing the jiffies (use CONFIG_PRINTK_TIME if you need timing) * remove the line numbers, they change with each applied patch It also changes the deprecated __FUNCTION__ to __func__ to make checkpatch.pl happy.

This patch reorders some fields in various structures to have less padding within the structures, making them smaller. It doesn't yet make any type adjustments, but often size_t is used for example for IE lengths which is total overkill since size_t will be 8 bytes long on 64-bit yet the length can at most fill a u8.

This patch alters the A-MPDU MLME in sta_info to use dynamic allocation, thus drastically improving memory usage - from a constant ~2 Kbyte in the previous (static) allocation to a lower limit of ~200 Byte and an upper limit of ~2 Kbyte. Signed-off-by:
