2012-01-11sctp: Do not account for sizeof(struct sk_buff) in estimated rwndThomas Graf
[ Upstream commit a76c0adf60f6ca5ff3481992e4ea0383776b24d2 ] When checking whether a DATA chunk fits into the estimated rwnd a full sizeof(struct sk_buff) is added to the needed chunk size. This quickly exhausts the available rwnd space and leads to packets being sent which are much below the PMTU limit. This can lead to much worse performance. The reason for this behaviour was to avoid putting too much memory pressure on the receiver. The concept is not completely irational because a Linux receiver does in fact clone an skb for each DATA chunk delivered. However, Linux also reserves half the available socket buffer space for data structures therefore usage of it is already accounted for. When proposing to change this the last time it was noted that this behaviour was introduced to solve a performance issue caused by rwnd overusage in combination with small DATA chunks. Trying to reproduce this I found that with the sk_buff overhead removed, the performance would improve significantly unless socket buffer limits are increased. The following numbers have been gathered using a patched iperf supporting SCTP over a live 1 Gbit ethernet network. The -l option was used to limit DATA chunk sizes. The numbers listed are based on the average of 3 test runs each. Default values have been used for sk_(r|w)mem.

2012-01-11sctp: fix incorrect overflow check on autocloseXi Wang
[ Upstream commit 2692ba61a82203404abd7dd2a027bda962861f74 ] Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for limiting the autoclose value. If userspace passes in -1 on 32-bit platform, the overflow check didn't work and autoclose would be set to 0xffffffff. This patch defines a max_autoclose (in seconds) for limiting the value and exposes it through sysctl, with the following intentions. 1) Avoid overflowing autoclose * HZ. 2) Keep the default autoclose bound consistent across 32- and 64-bit platforms (INT_MAX / HZ in this patch). 3) Keep the autoclose value consistent between setsockopt() and getsockopt() calls.

2012-01-11mac80211: fix another race in aggregation startJohannes Berg
commit 15062e6a8524f5977f2cbdf6e3eb2f144262f74e upstream. Emmanuel noticed that when mac80211 stops the queues for aggregation that can leave a packet pending. This packet will be given to the driver after the AMPDU callback, but as a non-aggregated packet which messes up the sequence number etc. I also noticed by looking at the code that if packets are being processed while we clear the WANT_START bit, they might see it cleared already and queue up on tid_tx->pending. If the driver then rejects the new aggregation session we leak the packet. Fix both of these issues by changing this code to not stop the queues at all. Instead, let packets queue up on the tid_tx->pending queue instead of letting them get to the driver, and add code to recover properly in case the driver rejects the session. (The patch looks large because it has to move two functions to before their new use.)

2012-01-06sctp: Do not account for sizeof(struct sk_buff) in estimated rwndThomas Graf
[ Upstream commit a76c0adf60f6ca5ff3481992e4ea0383776b24d2 ] When checking whether a DATA chunk fits into the estimated rwnd a full sizeof(struct sk_buff) is added to the needed chunk size. This quickly exhausts the available rwnd space and leads to packets being sent which are much below the PMTU limit. This can lead to much worse performance. The reason for this behaviour was to avoid putting too much memory pressure on the receiver. The concept is not completely irational because a Linux receiver does in fact clone an skb for each DATA chunk delivered. However, Linux also reserves half the available socket buffer space for data structures therefore usage of it is already accounted for. When proposing to change this the last time it was noted that this behaviour was introduced to solve a performance issue caused by rwnd overusage in combination with small DATA chunks. Trying to reproduce this I found that with the sk_buff overhead removed, the performance would improve significantly unless socket buffer limits are increased. The following numbers have been gathered using a patched iperf supporting SCTP over a live 1 Gbit ethernet network. The -l option was used to limit DATA chunk sizes. The numbers listed are based on the average of 3 test runs each. Default values have been used for sk_(r|w)mem.

2012-01-06sctp: fix incorrect overflow check on autocloseXi Wang
[ Upstream commit 2692ba61a82203404abd7dd2a027bda962861f74 ] Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for limiting the autoclose value. If userspace passes in -1 on 32-bit platform, the overflow check didn't work and autoclose would be set to 0xffffffff. This patch defines a max_autoclose (in seconds) for limiting the value and exposes it through sysctl, with the following intentions. 1) Avoid overflowing autoclose * HZ. 2) Keep the default autoclose bound consistent across 32- and 64-bit platforms (INT_MAX / HZ in this patch). 3) Keep the autoclose value consistent between setsockopt() and getsockopt() calls.

commit 15062e6a8524f5977f2cbdf6e3eb2f144262f74e upstream. Emmanuel noticed that when mac80211 stops the queues for aggregation that can leave a packet pending. This packet will be given to the driver after the AMPDU callback, but as a non-aggregated packet which messes up the sequence number etc. I also noticed by looking at the code that if packets are being processed while we clear the WANT_START bit, they might see it cleared already and queue up on tid_tx->pending. If the driver then rejects the new aggregation session we leak the packet. Fix both of these issues by changing this code to not stop the queues at all. Instead, let packets queue up on the tid_tx->pending queue instead of letting them get to the driver, and add code to recover properly in case the driver rejects the session. (The patch looks large because it has to move two functions to before their new use.)

RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

2011-12-09cfg80211: fix race on init and driver registrationLuis R. Rodriguez
commit a042994dd377d86bff9446ee76151ceb6267c9ba upstream. There is a theoretical race that if hit will trigger a crash. The race is between when we issue the first regulatory hint, regulatory_hint_core(), gets processed by the workqueue and between when the first device gets registered to the wireless core. This is not easy to reproduce but it was easy to do so through the regulatory simulator I have been working on. This is a port of the fix I implemented there [1].

2011-12-09mac80211: fix race condition caused by late addBA responseNikolay Martynov
Upstream commit d305a6557b2c4dca0110f05ffe745b1ef94adb80. If addBA responses comes in just after addba_resp_timer has expired mac80211 will still accept it and try to open the aggregation session. This causes drivers to be confused and in some cases even crash. This patch fixes the race condition and makes sure that if addba_resp_timer has expired addBA response is not longer accepted and we do not try to open half-closed session.
