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:

This patch makes ieee80211_get_channel a static inline defined in cfg80211's header file which simply calls __ieee80211_get_channel to avoid symbol clashes with the ieee80211 code. The problem was pointed out by David Miller, thanks! Signed-off-by:

This patch add LEDS support to 3965 and 4965 drivers. It is based on led trigger and class. For our drivers we needed to avoid two things. 1- We receive led trigger on/off on each Rx\Tx frame. In our driver we can not call led command like that. In this driver once driver receive a start of traffic it call the led command to start blinking then we count all bytes of Tx and Rx frame, after two second we count the blink rate of last two second then id blink rate changed we call the led commands 2- Since we can call led command very often, we make sure we call the led command after we receive the statistics notification so we don't need to wake up the ucode id it is in sleep state. This patch was tested with 4965 and 3945. Signed-off-by:Mohamed Abbas <mabbas@linux.intel.com> Signed-off-by: Ian Schram<ischram@telenet.be> Signed-off-by:

The IPv6 BEET output function is incorrectly including the inner header in the payload to be protected. This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function. Thanks to Joakim Koskela for finding this problem. Signed-off-by:

The commits f3db4851 ([NETNS][IPV6] ip6_fib - fib6_clean_all handle several network namespaces) and 69ddb805 ([NETNS][IPV6] route6 - Make proc entry /proc/net/rt6_stats per namespace) made some proc files per net. Both of them introduced potential OOPS - get_proc_net can return NULL, but this check is lost - and a struct net leak - in case single_open() fails the previously got net is not put. Kill all these bugs with one patch. Signed-off-by:

Currently each vlan_groupd contains 8 pointers on arrays with 512 pointers on struct net_device each :) Such a construction "in many cases ... wastes memory". My proposal is to allow for some of these arrays pointers be NULL, meaning that there are no devices in it. When a new device is added to the vlan_group, the appropriate array is allocated. The check in vlan_group_get_device's is safe, since the pointer vg->vlan_devices_arrays[x] can only switch from NULL to not-NULL. The vlan_group_prealloc_vid() is guarded with rtnl lock and is also safe. I've checked (I hope that) all the places, that use these arrays and found, that the register_vlan_dev is the only place, that can put a vlan device on an empty vlan_group. Rough calculations shows, that after the patch a setup with a single vlan dev (or up to 512 vlans with sequential vids) will occupy approximately 8 times less memory. The question I have is - does this patch makes sense, or a totally new structures are required to store the vlan_devs? Signed-off-by:
