The function get_net_ns_by_pid(), to get a network namespace from a pid_t, will be required in cfg80211 as well. Therefore, let's move it to net_namespace.c and export it. We can't make it a static inline in the !NETNS case because it needs to verify that the given pid even exists (and return -ESRCH). Signed-off-by:

This makes generic netlink network namespace aware. No generic netlink families except for the controller family are made namespace aware, they need to be checked one by one and then set the family->netnsok member to true. A new function genlmsg_multicast_netns() is introduced to allow sending a multicast message in a given namespace, for example when it applies to an object that lives in that namespace, a new function genlmsg_multicast_allns() to send a message to all network namespaces (for objects that do not have an associated netns). The function genlmsg_multicast() is changed to multicast the message in just init_net, which is currently correct for all generic netlink families since they only work in init_net right now. Some will later want to work in all net namespaces because they do not care about the netns at all -- those will have to be converted to use one of the new functions genlmsg_multicast_allns() or genlmsg_multicast_netns() whenever they are made netns aware in some way. After this patch families can easily decide whether or not they should be available in all net namespaces. Many genl families us it for objects not related to networking and should therefore be available in all namespaces, but that will have to be done on a per family basis. Note that this doesn't touch on the checkpoint/restart problem where network namespaces could be used, genl families and multicast groups are numbered globally and I see no easy way of changing that, especially since it must be possible to multicast to all network namespaces for those families that do not care about netns.

All we need to take care of is using proper RCU list add/del primitives and inserting a synchronize_rcu() at one place to make sure the exit notifiers are run after everybody has stopped iterating the list. Signed-off-by:

For the network namespace work in generic netlink I need to be able to call this function under rcu_read_lock(), otherwise the locking becomes a nightmare and more locks would be needed. Instead, just embed a struct rcu_head (actually a struct listeners_rcu_head that also carries the pointer to the memory block) into the listeners memory so we can use call_rcu() instead of synchronising and then freeing. No rcu_barrier() is needed since this code cannot be modular. Signed-off-by:

I added those myself in commits b4ff4f04 and 84659eb5, but I see no reason now why they should be exported, only generic netlink uses them which cannot be modular. Signed-off-by:

We've named the registered devices 'drv' sometimes, thinking of "driver", which is not what it is, it's the internal representation of a wiphy, i.e. a device. Let's clean up the naming once and and use 'rdev' aka 'registered device' everywhere. Signed-off-by:

Over time, a lot of locking issues have crept into the smarts of cfg80211, so e.g. scan completion can race against a new scan, IBSS join can race against leaving an IBSS, etc. Introduce a new per-interface lock that protects most of the per-interface data that we need to keep track of, and sprinkle assertions about that lock everywhere. Some things now need to be offloaded to work structs so that we don't require being able to sleep in functions the drivers call. The exception to that are the MLME callbacks (rx_auth etc.) that currently only mac80211 calls because it was easier to do that there instead of in cfg80211, and future drivers implementing those calls will, if they ever exist, probably need to use a similar scheme like mac80211 anyway... In order to be able to handle _deauth and _disassoc properly, introduce a cookie passed to it that will determine locking requirements. Signed-off-by:

The original code in mac80211 could send a deauth frame under certain circumstances even if nothing had ever requested an authentication. This has been fixed with the rework there, so cfg80211 can now warn again about spurious events to catch possible future drivers or mac80211 regressions. Signed-off-by:

We shouldn't be looking at the ssid_len for non-IBSS, and for IBSS we should also return an error on trying to leave an IBSS while not in or joining an IBSS. This fixes an issue where we wouldn't disconnect() on an interface being taken down since there's no SSID configured this way. Signed-off-by:

The new key work for cfg80211 will only give us the WEP key for shared auth to do that authentication, and not via the regular key settings, so we need to be able to encrypt a single frame in software, and that without a key struct. Thus, refactor the WEP code to not require a key structure but use the key, len and idx directly. Signed-off-by:

Sit tight. This shakes up the world as you know it. Let go of your spaghetti tongs, they will no longer be required, the horrible statemachine in net/mac80211/mlme.c is no more... With the cfg80211 SME mac80211 now has much less to keep track of, but, on the other hand, for FT it needs to be able to keep track of at least one authentication being in progress while associated. So convert from a single state machine to having small ones for all the different things we need to do. For real FT it will still need work wrt. PS, but this should be a good step. Signed-off-by:

This patch squashes a few old bugs, which have been around since the initial version of p54usb in one form or another. we never freed a orphaned frame, when were denied the resources, which are necessary to pass the data into the usb subsystem. As a result we could end up with a full queue that wasn't emptied, until the device was brought down. Signed-off-by:

We've designed the /dev/rfkill API in a way that we can increase the event struct by adding members at the end, should it become necessary. To validate the events, userspace and the kernel need to have the proper event size to check for -- when reading from the other end they need to verify that it's at least version 1 of the event API, with the current struct size, so define a constant for that and make the code a little more 'future proof'. Not that I expect that we'll have to change the event size any time soon, but it's better to write the code in a way that lends itself to extending. Due to the current size of the event struct, the code is currently equivalent, but should the event struct ever need to be increased the new code might not need changing. Signed-off-by:

"Ath5k: unify resets" introduced a regression into 2.6.28 where the PCU registers are never initialized, due to ath5k_reset() always passing true for change_channel. We subsequently program a lot of these registers but several may start in an unknown state. Cc: stable@kernel.org Reported-by:

Using the enable_beacon flag allows some simplifications and fixes some corner cases in beacon handling. This change adds a state variable for beaconing in ath5k_beacon_config and handles both enabling and disabling, thus eliminating the need for ath5k_beacon_disable. We also now configure the beacon when any of the beacon parameters change, so ath5k_beacon_reconfig is no longer needed (its mmiowb gets moved to ath5k_beacon_config). Finally, by locking around the whole config function, we don't need to worry about clearing the interrupt mask register before installing the new mask. The upshot is this correctly disables beaconing when the interfaces are taken down, it fixes a potential restarting of beaconing when ath5k_reset() is called, and ensures that updates to the beacon interval take effect immediately.

mac80211's software scan implementation uses a passive dwell time of (HZ / 5) which means we stay 200ms on each passive channel. Compared to iwlwifi's hw scan and the old ipw* drivers which use values around 120ms this is quite long. Reducing the passive dwell time from 200ms to 125ms should save us something around a second on cards capable of 11a and we should still be able to catch beacons from most access points (assuming a ~100ms beacon interval).
