This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.

mac80211 currently assumes init_net for all interfaces, so really will not cope well with network namespaces, at least at this time. To change this, we would have keep track of the netns in addition to the ifindex, which is not something I want to think about right now.

Currently there are two paths for filling rx buffer queues. One is used during initialization and the other during runtime. This patch removes ql_alloc_sbq_buffers() and ql_alloc_lbq_buffers() and replaces them with a call to the runtime functions ql_update_lbq() and ql_update_sbq().

This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

it was pointed out on the list that ixgbe was failing when using 64kB pages and large 16kB MTU. since with a 64kB PAGE_SIZE MAX_SKB_FRAGS = 3, the way the driver was configuring page usage was assuming 2kB is half a page, and was only ever dmaing that much data to a half page. (16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to 16kB for each descriptor.

Fix regression introduded by commit 079aa88f (netfilter: xt_recent: IPv6 support): From http://bugzilla.kernel.org/show_bug.cgi?id=12753: Problem Description: An uninitialized buffer causes IPv4 addresses added manually (via the +IP command to the proc interface) to never match any packets. Similarly, the -IP command fails to remove IPv4 addresses. Details: In the function recent_entry_lookup, the xt_recent module does comparisons of the entire nf_inet_addr union value, both for IPv4 and IPv6 addresses. For addresses initialized from actual packets the remaining 12 bytes not occupied by the IPv4 are zeroed so this works correctly. However when setting the nf_inet_addr addr variable in the recent_mt_proc_write function, only the IPv4 bytes are initialized and the remaining 12 bytes contain garbage. Hence addresses added in this way never match any packets, unless these uninitialized 12 bytes happened to be zero by coincidence. Similarly, addresses cannot consistently be removed using the proc interface due to mismatch of the garbage bytes (although it will sometimes work to remove an address that was added manually). Reading the /proc/net/xt_recent/ entries hides this problem because this only uses the first 4 bytes when displaying IPv4 addresses. Steps to reproduce: $ iptables -I INPUT -m recent --rcheck -j LOG $ echo +169.254.156.239 > /proc/net/xt_recent/DEFAULT $ cat /proc/net/xt_recent/DEFAULT src=169.254.156.239 ttl: 0 last_seen: 119910 oldest_pkt: 1 119910 [At this point no packets from 169.254.156.239 are being logged.] $ iptables -I INPUT -s 169.254.156.239 -m recent --set $ cat /proc/net/xt_recent/DEFAULT src=169.254.156.239 ttl: 0 last_seen: 119910 oldest_pkt: 1 119910 src=169.254.156.239 ttl: 255 last_seen: 126184 oldest_pkt: 4 125434, 125684, 125934, 126184 [At this point, adding the address via an iptables rule, packets are being logged correctly.] $ echo -169.254.156.239 > /proc/net/xt_recent/DEFAULT $ cat /proc/net/xt_recent/DEFAULT src=169.254.156.239 ttl: 0 last_seen: 119910 oldest_pkt: 1 119910 src=169.254.156.239 ttl: 255 last_seen: 126992 oldest_pkt: 10 125434, 125684, 125934, 126184, 126434, 126684, 126934, 126991, 126991, 126992 $ echo -169.254.156.239 > /proc/net/xt_recent/DEFAULT $ cat /proc/net/xt_recent/DEFAULT src=169.254.156.239 ttl: 0 last_seen: 119910 oldest_pkt: 1 119910 src=169.254.156.239 ttl: 255 last_seen: 126992 oldest_pkt: 10 125434, 125684, 125934, 126184, 126434, 126684, 126934, 126991, 126991, 126992 [Removing the address via /proc interface failed evidently.] Possible solutions: - initialize the addr variable in recent_mt_proc_write - compare only 4 bytes for IPv4 addresses in recent_entry_lookup Signed-off-by: NPatrick McHardy <kaber@trash.net>
