* [ARP]: Introduce the arp_hdr_len helper.Pavel Emelyanov2008-03-03
| | | | | | | | | | | | | | 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.

| * mac80211: fix key replacing, hw accelJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mac80211: split ieee80211_key_alloc/freeJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | 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.)

| * mac80211: atomically check whether STA exists alreadyJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
