2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2015-05-29mac80211: prevent possible crypto tx tailroom corruptionMichal Kazior
There was a possible race between ieee80211_reconfig() and ieee80211_delayed_tailroom_dec(). This could result in inability to transmit data if driver crashed during roaming or rekeying and subsequent skbs with insufficient tailroom appeared. This race was probably never seen in the wild because a device driver would have to crash AND recover within 0.5s which is very unlikely. I was able to prove this race exists after changing the delay to 10s locally and crashing ath10k via debugfs immediately after GTK rekeying. In case of ath10k the counter went below 0. This was harmless but other drivers which actually require tailroom (e.g. for WEP ICV or MMIC) could end up with the counter at 0 instead of >0 and introduce insufficient skb tailroom failures because mac80211 would not resize skbs appropriately anymore.

2015-05-20mac80211: fix memory leakJohannes Berg
My recent change here introduced a possible memory leak if the driver registers an invalid cipher schemes. This won't really happen in practice, but fix the leak nonetheless.

2015-05-06mac80211: validate cipher scheme PN length betterJohannes Berg
Currently, a cipher scheme can advertise an arbitrarily long sequence counter, but mac80211 only supports up to 16 bytes and the initial value from userspace will be truncated. Fix two things: * don't allow the driver to register anything longer than the 16 bytes that mac80211 reserves space for * require userspace to specify a starting value with the correct length (or none at all) Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-05-05mac80211: make LED triggering depend on activationJohannes Berg
When LED triggers are compiled in, but not used, mac80211 will still call them to update the status. This isn't really a problem for the assoc and radio ones, but the TX/RX (and to a certain extend TPT) ones can be called very frequently (for every packet.) In order to avoid that when they're not used, track their activation and call the corresponding trigger (and in the TPT case, account for throughput) only when the trigger is actually used by an LED. Additionally, make those trigger functions inlines since theyre only used once in the remaining code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-04-22mac80211: allow drivers to support S/GJohannes Berg
If drivers want to support S/G (really just gather DMA on TX) then we can now easily support this on the fast-xmit path since it just needs to write to the ethernet header (and already has a check for that being possible.) However, disallow this on the regular TX path (which has to handle fragmentation, software crypto, etc.) by calling skb_linearize(). Also allow the related HIGHDMA since that's not interesting to the code in mac80211 at all anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-04-01mac80211: add an intermediate software queue implementationFelix Fietkau
This allows drivers to request per-vif and per-sta-tid queues from which they can pull frames. This makes it easier to keep the hardware queues short, and to improve fairness between clients and vifs. The task of scheduling packet transmission is left up to the driver - queueing is controlled by mac80211. Drivers can only dequeue packets by calling ieee80211_tx_dequeue. This makes it possible to add active queue management later without changing drivers using this code. This can also be used as a starting point to implement A-MSDU aggregation in a way that does not add artificially induced latency.

2015-04-01mac80211: use rhashtable for station tableJohannes Berg
We currently have a hand-rolled table with 256 entries and are using the last byte of the MAC address as the hash. This hash is obviously very fast, but collisions are easily created and we waste a lot of space in the common case of just connecting as a client to an AP where we just have a single station. The other common case of an AP is also suboptimal due to the size of the hash table and the ease of causing collisions. Convert all of this to use rhashtable with jhash, which gives us the advantage of a far better hash function (with random perturbation to avoid hash collision attacks) and of course that the hash table grows and shrinks dynamically with chain length, improving both cases above. Use a specialised hash function (using jhash, but with fixed length) to achieve better compiler optimisation as suggested by Sergey Ryazanov. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-03-30cfg80211: pass name_assign_type to rdev_add_virtual_intf()Tom Gundersen
This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

2015-02-28mac80211: remove TX latency measurement codeJohannes Berg
Revert commit ad38bfc916da ("mac80211: Tx frame latency statistics") (along with some follow-up fixes). This code turned out not to be as useful in the current form as we thought, and we've internally hacked it up more, but that's not very suitable for upstream (for now), and we might just do that with tracing instead. Therefore, for now at least, remove this code. We might also need to use the skb->tstamp field for the TCP performance issue, which is more important than the debugging.

2015-01-22mac80211: allow drivers to control software cryptoJohannes Berg
Some drivers unfortunately cannot support software crypto, but mac80211 currently assumes that they do. This has the issue that if the hardware enabling fails for some reason, the software fallback is used, which won't work. This clearly isn't desirable, the error should be reported and the key setting refused. Support this in mac80211 by allowing drivers to set a new HW flag IEEE80211_HW_SW_CRYPTO_CONTROL, in which case mac80211 will only allow software fallback if the set_key() method returns 1. The driver will also need to advertise supported cipher suites so that mac80211 doesn't advertise any (future) software ciphers that the driver can't actually do. While at it, to make it easier to support this, refactor the ieee80211_init_cipher_suites() code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-01-21mac80211: fix HW registration error pathsJohannes Berg
Station info state is started in allocation, so should be destroyed on free (it's just a timer); rate control must be freed if anything afterwards fails to initialize. LED exit should be later, no need for locking there, but it needs to be done also when rate init failed. Also clean up the code by moving a label so the locking doesn't have to be done separately.

2014-02-12mac80211: add NAPI support backJohannes Berg
NAPI was originally added to mac80211 a long time ago (by John in commit 4e6cbfd09c66 in July 2010), but then removed years later (by Stanislaw in commit 30c97120c6c7 in February 2013). No driver ever used it, so that was fine. Now I'm adding support for NAPI to our driver, so add some code to mac80211 again to support NAPI. John was originally wrapping some (but not nearly all NAPI-related functions), but that doesn't scale very well with the number of functions that are there, some of which are even only inlines. Thus, instead of doing that, let the drivers manage the NAPI struct, except for napi_add() which is needed so mac80211 knows how to call napi_gro_receive(). Also remove some no longer needed definitions that were left when NAPI support was removed.

The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses.
