| * mac80211: clean up rate control APIJohannes Berg2008-09-241-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Long awaited, hard work. This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it. It's still off better than before. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | Currently the mesh code doesn't support bridging mesh point interfaces with wired ethernet or AP to construct an MPP or MAP. This patch adds code to support the "6 address frame format packet" functionality to mesh point interfaces. Now the mesh network can be used as backhaul for end to end communication.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address'). If we are a bit smarter about the encoding of the phy_addr field, we can avoid the need for a second field -- this patch does that. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add support for keeping an additional character alias associated with an network interface. This is useful for maintaining the SNMP ifAlias value which is a user defined value. Routers use this to hold information like which circuit or line it is connected to. It is just an arbitrary text label on the network device. There are two exposed interfaces with this patch, the value can be read/written either via netlink or sysfs. This could be maintained just by the snmp daemon, but it is more generally useful for other management tools, and the kernel is good place to act as an agreed upon interface to store it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discovered by Timo Teräs, the currently xfrm_state_walk scheme is racy because if a second dump finishes before the first, we may free xfrm states that the first dump would walk over later. This patch fixes this by storing the dumps in a list in order to calculate the correct completion counter which cures this problem. I've expanded netlink_cb in order to accomodate the extra state related to this. It shouldn't be a big deal since netlink_cb is kmalloced for each dump and we're just increasing it by 4 or 8 bytes.

Since retransmit_high must be kept valid, all lost markers must ensure that. Now I also have learned how those "holes" in the rexmittable skbs can appear, mtu probe does them.

| * | mac80211: fix virtual interfaces vs. injectionJohannes Berg2008-09-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, virtual interface pointers passed to drivers might be from monitor interfaces and as such completely uninitialised because we do not tell the driver about monitor interfaces when those are created. Instead of passing them, we should therefore indicate to the driver that there is no information; do that by passing a NULL value and adjust drivers to cope with it. As a result, some mac80211 API functions also need to cope with a NULL vif pointer so drivers can still call them unconditionally. Also, when injecting frames we really don't want to pass NULL all the time, if we know we are the source address of a frame and have a local interface for that address, we can to use that interface. This also helps with processing the frame correctly for that interface which will help the 802.11w implementation. It's not entirely correct for VLANs or WDS interfaces because there the MAC address isn't unique, but it's already a lot better than what we do now. Finally, when injecting without a matching local interface, don't assign sequence numbers at all. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Alternatively, a scan that started as a hardware scan may terminate as though it was a software scan, if the timing is just right. On SMP systems, software scan also has a similar problem, just canceling the delayed work and setting a flag isn't enough since it may be running concurrently; in this case we would also never restore state of other interfaces. This patch hopefully fixes the problems by always invoking ieee80211_scan_completed or requiring it to be invoked by the driver, I suspect the drivers that have ->hw_scan() are buggy. The bug will not manifest itself unless you remove the interface while hw-scanning which will also turn off the hw, and then add a new interface which will be unusable until you scan once.

The main motiviation behind this was to centralize regulatory code as each driver was implementing their own regulatory solution, and to replace the initial centralized code we have where: * only 3 regulatory domains are supported: US, JP and EU * regulatory domains can only be changed through module parameter * all rules were built statically in the kernel We now have support for regulatory domains for many countries and regulatory domains are now queried through a userspace agent through udev allowing distributions to update regulatory rules without updating the kernel. Each driver can regulatory_hint() a regulatory domain based on either their EEPROM mapped regulatory domain value to a respective ISO/IEC 3166-1 country code or pass an internally built regulatory domain. We also add support to let the user set the regulatory domain through userspace in case of faulty EEPROMs to further help compliance. Support for world roaming will be added soon for cards capable of this. For more information see: http://wireless.kernel.org/en/developers/Regulatory/CRDA For now we leave an option to enable the old module parameter, ieee80211_regdom, and to build the 3 old regdomains statically (US, JP and EU). This option is CONFIG_WIRELESS_OLD_REGULATORY. These old static definitions and the module parameter is being scheduled for removal for 2.6.29. Note that if you use this you won't make use of a world regulatory domain as its pointless. If you leave this option enabled and if CRDA is present and you use US or JP we will try to ask CRDA to update us a regulatory domain for us. Signed-off-by: Luis R.
