2007-10-26[PATCH] mac80211: fix printk warning on 64-bitJohannes Berg
My AID message patch introduced a warning on 64-bit machines because ~ extends to unsigned long: | net/mac80211/ieee80211_sta.c: In function ‘ieee80211_rx_mgmt_assoc_resp’: | net/mac80211/ieee80211_sta.c:1187: warning: format ‘%d’ expects type ‘int’, but argument 7 has type ‘long unsigned int’ This fixes it by explicitly casting the result to u16 (which 'aid' is).

Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

2007-10-18[PATCH] mac80211: make ieee802_11_parse_elems return voidJohn W. Linville
Some APs send management frames with junk padding after the last IE. We already account for a similar problem with some Apple Airport devices, but at least one device is known to send more than a single extra byte. The device in question is the Draytek Vigor2900: http://www.draytek.com.au/products/Vigor2900.php The junk in question looks like an IE that runs off the end of the frame. This cause us to return ParseFailed. Since the frame in question is an association response, this causes us to fail to associate with this AP. The return code from ieee802_11_parse_elems is superfluous. All callers still check for the presence of the specific IEs that interest them anyway. So, remove the return code so the parse never "fails". Acked-by: Michael Wu <flamingice@sourmilk.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2007-10-10[PATCH] ieee80211_if_set_type: make check for master dev more explicitJohn W. Linville
Problem description by Daniel Drake <dsd@gentoo.org>: "This sequence of events causes loss of connectivity: <plug in> <associate as normal in managed mode> ifconfig eth7 down iwconfig eth7 mode monitor ifconfig eth7 up ifconfig eth7 down iwconfig eth7 mode managed <associate as normal> At this point you are associated but TX does not work. This is because the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit." The problem is caused by ieee80211_if_set_type checking for a non-zero hard_start_xmit pointer value in order to avoid changing that value for master devices. The fix is to make that check more explicitly linked to master devices rather than simply checking if the value has been previously set.

2007-10-10[PATCH] mac80211: fix iff_promiscs, iff_allmultis raceJohannes Berg
When we update the counters iff_promiscs and iff_allmultis in struct ieee80211_local we have no common lock held to protect them. The problem is that the update to each counter may not be atomic, so we could end up with iff_promiscs == -1 in unfortunate conditions. To fix it, use atomic_t values. It doesn't matter whether the two counters are updated together atomically or not, if there are two invocations of set_multicast_list we will end up with multiple configure_filter() invocations of which the latter will always be correct.

2007-10-10[PATCH] mac80211: fix interface initialisation and deinitialisationJohannes Berg
When an interface is registered it is still uninitialised so ieee80211_if_reinit() can't be called on it (it will oops.) Hence, we need to move the uninit method assignment. Also, this patch fixes the bug that the master device is never initialised nor deinitialised at all. Oddly, the deinit code had an if statement to not run some code when running for the master interface (which never happened), but that if statement is also wrong. Fix that too. Now that the uninit code is run for the master device, another bug surfaced: it tries to remove all dependent interfaces and that oopses or BUGs at some point, either because it unregisters already unregistered interfaces (missing list_del bug) or due to trying to iterate a list that has had other things removed. Fix this too by handling the master interface specially. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-10-10[PATCH] mac80211: fix virtual interface lockingJohannes Berg
Florian Lohoff noticed a bug in mac80211: when bringing the master interface down while other virtual interfaces are up we call dev_close() under a spinlock which is not allowed. This patch removes the sub_if_lock used by mac80211 in favour of using an RCU list. All list manipulations are already done under rtnl so are well protected against each other, and the read-side locks we took in the RX and TX code are already in RCU read-side critical sections.

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
