2010-11-18nl80211/mac80211: Report signal averageBruno Randolf
Extend nl80211 to report an exponential weighted moving average (EWMA) of the signal value. Since the signal value usually fluctuates between different packets, an average can be more useful than the value of the last packet. This uses the recently added generic EWMA library function.

2010-11-16cfg80211: Add nl80211 antenna configurationBruno Randolf
Allow setting of TX and RX antennas configuration via nl80211. The antenna configuration is defined as a bitmap of allowed antennas to use. This API can be used to mask out antennas which are not attached or should not be used for other reasons like regulatory concerns or special setups. Separate bitmaps are used for RX and TX to allow configuring different antennas for receiving and transmitting. Each bitmap is 32 bit long, each bit representing one antenna, starting with antenna 1 at the first bit. If an antenna bit is set, this means the driver is allowed to use this antenna for RX or TX respectively; if the bit is not set the hardware is not allowed to use this antenna. Using bitmaps has the benefit of allowing for a flexible configuration interface which can support many different configurations and which can be used for 802.11n as well as non-802.11n devices. Instead of relying on some hardware specific assumptions, drivers can use this information to know which antennas are actually attached to the system and derive their capabilities based on that. 802.11n devices should enable or disable chains, based on which antennas are present (If all antennas belonging to a particular chain are disabled, the entire chain should be disabled). HT capabilities (like STBC, TX Beamforming, Antenna selection) should be calculated based on the available chains after applying the antenna masks. Should a 802.11n device have diversity antennas attached to one of their chains, diversity can be enabled or disabled based on the antenna information. Non-802.11n drivers can use the antenna masks to select RX and TX antennas and to enable or disable antenna diversity. While covering chainmasks for 802.11n and the standard "legacy" modes "fixed antenna 1", "fixed antenna 2" and "diversity" this API also allows more rare, but useful configurations as follows: 1) Send on antenna 1, receive on antenna 2 (or vice versa). This can be used to have a low gain antenna for TX in order to keep within the regulatory constraints and a high gain antenna for RX in order to receive weaker signals ("speak softly, but listen harder"). This can be useful for building long-shot outdoor links. Another usage of this setup is having a low-noise pre-amplifier on antenna 1 and a power amplifier on the other antenna. This way transmit noise is mostly kept out of the low noise receive channel. (This would be bitmaps: tx 1 rx 2). 2) Another similar setup is: Use RX diversity on both antennas, but always send on antenna 1. Again that would allow us to benefit from a higher gain RX antenna, while staying within the legal limits. (This would be: tx 0 rx 3). 3) And finally there can be special experimental setups in research and development even with pre 802.11n hardware where more than 2 antennas are available. It's good to keep the API simple, yet flexible. Signed-off-by: Bruno Randolf <br1@einfach.org> -- v7: Made bitmasks 32 bit wide and rebased to latest wireless-testing. Signed-off-by: John W.

2010-11-16cfg80211: fix extension channel checks to initiate communicationLuis R. Rodriguez
When operating in a mode that initiates communication and using HT40 we should fail if we cannot use both primary and secondary channels to initiate communication. Our current ht40 allowmap only covers STA mode of operation, for beaconing modes we need a check on the fly as the mode of operation is dynamic and there other flags other than disable which we should read to check if we can initiate communication. Do not allow for initiating communication if our secondary HT40 channel has is either disabled, has a passive scan flag, a no-ibss flag or is a radar channel. Userspace now has similar checks but this is also needed in-kernel. Reported-by: Jouni Malinen <jouni.malinen@atheros.com> Cc: stable@kernel.org Signed-off-by: Luis R.

2010-11-15cfg80211: fix disabling channels based on hintsLuis R. Rodriguez
After a module loads you will have loaded the world roaming regulatory domain or a custom regulatory domain. Further regulatory hints are welcomed and should be respected unless the regulatory hint is coming from a country IE as the IEEE spec allows for a country IE to be a subset of what is allowed by the local regulatory agencies. So disable all channels that do not fit a regulatory domain sent from a unless the hint is from a country IE and the country IE had no information about the band we are currently processing. This fixes a few regulatory issues, for example for drivers that depend on CRDA and had no 5 GHz freqencies allowed were not properly disabling 5 GHz at all, furthermore it also allows users to restrict devices further as was intended. If you recieve a country IE upon association we will also disable the channels that are not allowed if the country IE had at least one channel on the respective band we are procesing. This was the original intention behind this design but it was completely overlooked...

2010-10-25cfg80211: fix regression on processing country IEsLuis R. Rodriguez
The patch 4f366c5: wireless: only use alpha2 regulatory information from country IE removed some complex intersection we were always doing between the AP's country IE info and what we got from CRDA. When CRDA sent us back a regulatory domain we would do some sanity checks on that regulatory domain response we just got. Part of these sanity checks included checking that we already had performed an intersection for the request of NL80211_REGDOM_SET_BY_COUNTRY_IE type. This mean that cfg80211 was only processing country IEs for cases where we already had an intersection, but since we removed enforcing this this is no longer required, we should just apply the country IE country hint with the data received from CRDA.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

The commit failed to take into account that allocated wireless devices (wiphys) are not added into the device list upon allocation, but only when they are registered. Therefore, it opened up a race between allocating and registering a name, so that if two processes allocate and register concurrently ("alloc, alloc, register, register" rather than "alloc, register, alloc, register") the code will attempt to use the same name twice.

When multiple interfaces are actively trying to associate with the same BSS, they may both find that the BSS isn't there and then try to unlink it. This can cause errors since the unlinking code can't currently deal with items that have already been unlinked. Normally this doesn't happen as most people don't try to use multiple station interfaces that associate at the same time too. Fix this by using the list entry as a flag to see if the item is still on a list.

2010-10-05wireless: Use first phyX name available when registering phy devices.Ben Greear
Choose first available phyX name when creating phy devices. This means that reloading a wifi driver will not cause a change in the name of it's phy device. Also, allow users to rename a phy to any un-used name, including phy%d. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-09-20wext: fix potential private ioctl memory content leakJohannes Berg
When a driver doesn't fill the entire buffer, old heap contents may remain, and if it also doesn't update the length properly, this old heap content will be copied back to userspace. It is very unlikely that this happens in any of the drivers using private ioctls since it would show up as junk being reported by iwpriv, but it seems better to be safe here, so use kzalloc.
