* [PATCH] mac80211: ERP IE handling improvementsDaniel Drake2007-07-123-19/+67
| | | | | | | | | | | | | | | The "protection needed" flag is currently parsed out of the ERP IE in beacons. This patch allows the ERP IE to be available at assocation time and causes the appropriate actions to be performed earlier. It is slightly complicated by the fact that most APs don't include the ERP IE in association responses. To work around this, we store ERP values in the ieee80211_sta_bss structure. Also added some WLAN_ERP defines for use by upcoming patches. Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [PATCH] mac80211: Implementation of SIOCSIWRATELarry Finger2007-07-121-1/+39
| | | | | | | | | | | | The WEXT ioctl SIOCSIWRATE is not implemented in mac80211. This patch adds the missing routine. It supports the 'auto' keyword, fixed rates, and the combination of 'auto' and a fixed rate to select an upper bound. Based on the patch from Mohamed Abbas <mabbas@linux.intel.com>.

* [PATCH] mac80211: clarify some mac80211 thingsJohannes Berg2007-07-122-21/+24
| | | | | | | | | | | | | The semantics of not having an add_interface callback are not well defined, this callback is required because otherwise you cannot obtain the requested MAC address of the device. Change the documentation to reflect this, add a note about having no MAC address at all, add a warning that mac_addr in struct ieee80211_if_init_conf can be NULL and finally verify that a few callbacks are assigned by way of BUG_ON() Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W.

* [TG3]: Fix the polarity bit.Matt Carlson2007-07-111-19/+44
| | | | | | | | | | | | | | | | | | | | For most pre-5705 devices, multiple link interrupts were being generated for a single physical link change. The source of the interrupts was determined to be unnecessary toggling of the MAC link polarity bit. This patch changes the way the link polarity bit gets configured. Where possible, code that dynamically configures the bit in response to link changes has been replaced by code that configures the bit once during initialization time and then leaves the bit alone. For correctness, this patch also limits the use of the bit to those devices where it is defined, namely devices before the 5705. This patch also corrects the link polarity configurations for 5700 devices when paired against a bcm5411 phy.

* [TG3]: Fix irq_sync race condition.Michael Chan2007-07-111-3/+3
| | | | | | | | | | | | | | | | | | Gagan Arneja <gaagaan@gmail.com> pointed out that tg3_reset_task() could potentially race with another thread calling tg3_full_lock() such as the ethtool_set_xxx() functions. This may trigger the BUG_ON() in tg3_irq_quiesce() or cause the irq_sync flag to be out- of-sync. I think the easiest way to fix this is to get the tp->lock first before setting the irq_sync flag. This is safe to do because the tp->lock is never grabbed by the irq handler. This change will guarantee that the irq_sync flag updates will be serialized. We also have to change one spot to call tg3_netif_start() (which clears the irq_sync flag) before releasing the tp->lock. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [RTNETLINK]: rtnl_link API simplificationPatrick McHardy2007-07-114-131/+23
| | | | | | | | | | | | | | All drivers need to unregister their devices in the module unload function. While doing so they must hold the rtnl and atomically unregister the rtnl_link ops as well. This makes the rtnl_link_unregister function that takes the rtnl itself completely useless. Provide default newlink/dellink functions, make __rtnl_link_unregister and rtnl_link_unregister unregister all devices with matching rtnl_link_ops and change the existing users to take advantage of that.

* [VLAN]: Fix MAC address handlingPatrick McHardy2007-07-114-45/+57
| | | | | | | | | | | | | | | | | | The VLAN MAC address handling is broken in multiple ways. When the address differs when setting it, the real device is put in promiscous mode twice, but never taken out again. Additionally it doesn't resync when the real device's address is changed and needlessly puts it in promiscous mode when the vlan device is still down. Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly deal with address changes in the device notifier. Also switch to dev_unicast_add (which needs the exact same handling). Since the set_mac_address handler is identical to the generic ethernet one with these changes, kill it and use ether_setup(). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Throw out the old mark & sweep garbage collector and put in a refcounting cycle detecting one. The old one had a race with recvmsg, that resulted in false positives and hence data loss. The old algorithm operated on all unix sockets in the system, so any additional locking would have meant performance problems for all users of these. The new algorithm instead only operates on "in flight" sockets, which are very rare, and the additional locking for these doesn't negatively impact the vast majority of users. In fact it's probable, that there weren't *any* heavy senders of sockets over sockets, otherwise the above race would have been discovered long ago. The patch works OK with the app that exposed the race with the old code. The garbage collection has also been verified to work in a few simple cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 93ec2c723e3f8a216dde2899aeb85c648672bc6b applied excessive duct tape to the netpoll beast's netpoll_cleanup(), thus substituting one leak with another, and opening up a little buglet :-) net_device->npinfo (netpoll_info) is a shared and refcounted object and cannot simply be set NULL the first time netpoll_cleanup() is called. Otherwise, further netpoll_cleanup()'s see np->dev->npinfo == NULL and become no-ops, thus leaking. And it's a bug too: the first call to netpoll_cleanup() would thus (annoyingly) "disable" other (still alive) netpolls too. Maybe nobody noticed this because netconsole (only user of netpoll) never supported multiple netpoll objects earlier. This is a trivial and obvious one-line fixlet.
