2008-03-04[IPV6] ADDRCONF: Convert ipv6_get_saddr() to ipv6_dev_get_saddr().YOSHIFUJI Hideaki
Since most users of ipv6_get_saddr() pass non-NULL as dst argument, use ipv6_dev_get_saddr() directly. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
2008-03-04[NET] NEIGHBOUR: Remove unpopular neigh_is_connected().YOSHIFUJI Hideaki
neigh_is_connected() is not popular at all, and the only user drivers/net/cxgb3/l2t.c:t3_l2t_update() also have raw (expanded) expression. Let's expand it and remove the inline function. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>

2008-03-03[ARP]: Introduce the arp_hdr_len helper.Pavel Emelyanov
There are some place, that calculate the ARP header length. These calculations are correct, but a) some operate with "magic" constants, b) enlarge the code length (sometimes at the cost of coding style), c) are not informative from the first glance. The proposal is to introduce a helper, that includes all the good sides of these calculations. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-02-29mac80211: fix key replacing, hw accelJohannes Berg
Even though I thought about it a lot and had also tested it, some of my recent changes in the key code broke replacing keys, making the kernel oops because a key is removed from a list while not on it. This patch fixes that using the list as an indication whether or not the key is on it (an empty list means it's not on any list.) Also, this patch fixes hw accel enabling, the check for not doing hw accel when the interface is down was lost and is restored by this. Additionally, move adding the key to the list into the function __ieee80211_key_replace() for more consistency. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: split ieee80211_key_alloc/freeJohannes Berg
In order to RCU-ify sta_info, we need to be able to allocate a key without linking it to an sdata/sta structure (because allocation cannot be done in an rcu critical section). This patch splits up ieee80211_key_alloc() and updates all users appropriately. While at it, this patch fixes a number of race conditions such as finally making key replacement atomic, unfortunately at the expense of more complex code. Note that this patch documents /existing/ bugs with sta info and key interaction, there is currently a race condition when a sta info is freed without holding the RTNL. This will finally be fixed by a followup patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: remove STA infos last_ack stuffJohannes Berg
These things aren't used and the only possible use is within rate control algorithms, however those can, if they need it, keep track of it in their private data. last_ack_ms isn't even updated so completely useless.

2008-02-29mac80211: safely free beacon in ieee80211_if_reinitJohannes Berg
If ieee80211_if_reinit() is called from ieee80211_unregister_hw() then it is possible that the driver will still request a beacon (it is allowed to until ieee80211_unregister_hw() has returned.) This means we need to use an RCU-protected write to the beacon information even in this function. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: clarify use of TX status/RX callbacksJohannes Berg

2008-02-29mac80211: fix debugfs_sta print_mac() warningJohannes Berg
When print_mac() was marked as __pure to avoid emitting a function call in pr_debug() scenarios, a warning in this code surfaced since it relies on the fact that the buffer is modified and doesn't use the return value. This patch makes it use the return value instead. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Reported-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: Disallow concurrent IBSS/STA mode interfacesJohannes Berg
Disallow having more than one IBSS interface up at any time because of beacon distribution issues, and for now also disallow having more than one IBSS/STA interface up at the same time because we use the master interface's BSS struct which would be completely corrupted when we have more than one up.

2008-02-29mac80211: atomically check whether STA exists alreadyJohannes Berg
When a STA structure is added, it is often checked whether it already exists before adding it. This, however, isn't done atomically so there is a race condition that could lead to two STA structures being added with the same MAC address. This patch changes sta_info_add() to return an ERR_PTR in case of failure and adds the failure mode -EEXIST when the STA already exists.

2008-02-29mac80211: rework TX filtered frame codeJohannes Berg
This reworks the code for TX filtered frames, splitting it out to a new function to handle those cases, making the clear instruction a flag and renaming a few things to be easier to understand and less Atheros hardware specific. Finally, it also makes the comments explain more. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-02-29mac80211: consolidate TIM handling codeJohannes Berg
This consolidates all TIM handling code to avoid re-introducing errors with the bitmap/set_tim order and to reduce code. While reading the code I noticed a possible problem so I also added a comment about that. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: remove sta TIM flag, fix expiry TIM handlingJohannes Berg
The TIM flag that is kept in each station's info is completely useless, there's no code (aside from the debugfs display code) checking it, hence it can be removed. While doing that, I noticed that the TIM handling is broken when buffered frames expire, so fix that. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-29mac80211: invoke set_tim() callback after setting own TIM infoJohannes Berg
Drivers should be allowed to simply get a complete new beacon when set_tim() is invoked (and set_tim() is required for drivers that just want a beacon template!), so we need to update our own TIM bitmap before calling set_tim() so that getting the beacon will now get an already updated beacon.

2008-02-29rt2x00: Fix MAC address defines in rt61pciIvo van Doorn
The MAC address offset defines were incorrect because the byte offset was used instead of word index. This bug had no affect on normal operations since these defines weren't used.

2008-02-29rt2x00: Remove async vendor request calls from rt2x00usbIvo van Doorn
The async vendor requests are a ugly hack which is not working correctly. The proper fix for the scheduling while atomic issue is finding out why we can't use led classes for USB drivers and fix that. Just replace all async calls with the regular ones and print an error for the disallowed LED configuration attempts. That will help in determining which led class is causing the problem.
