2014-10-21mac80211: remove unnecessary null test before debugfs_remove()Fabian Frederick
The debugfs_remove() function can safely take NULL parameters so the additionally null test isn't required, and there's no other reason to have it here, so remove it.

2014-10-21mac80211: minstrel_ht: add basic support for VHT rates <= 3SS@80MHzKarl Beldan
When the new CONFIG_MAC80211_RC_MINSTREL_VHT is not set (default 'N'), there is no behavioral change including in sampling and MCS_GROUP_RATES remains 8. Otherwise MCS_GROUP_RATES is 10, and a module parameter *vht_only* (default 'true'), restricts the rates selection to VHT when VHT is supported. Regarding the debugfs stats buffer: It is explicitly increased from 8k to 32k to fit every rates incl. when both HT and VHT rates are enabled, as for the format, before: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) after: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) VHT40/LGI MCS5/2 0.0 0.0 0.0 0 0( 0) 0( 0) Signed-off-by: Karl Beldan <karl.beldan@rivierawaves.com> Cc: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-10-20mac80211: minstrel_ht: include type (cck/ht) in rates flagKarl Beldan
ATM, we grep cck rates idx with idx / MCS_GROUP_RATES == MINSTREL_CCK_GROUP. Matching neither-cck-non-ht rates could be done by replacing '==' with '>', however it would be less versatile or explicit. This will allow to match VHT rates with IEEE80211_TX_RC_VHT_MCS.

2014-10-20mac80211: minstrel_ht: Increase the range of handled rate indexesKarl Beldan
Since 5935839ad735 ("mac80211: improve minstrel_ht rate sorting by throughput & probability"), the rate indexes are manipulated via u8's and hence allow for a maximum of 256 mcs_group entries in minstrel_mcs_groups. ATM, minstrel_ht advertizes support up to 3HTSS@40MHz, consuming: 8(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)), i.e. 104 entries. Support for 3VHTSS@80MHz will require: 10(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)) + 10(MCS_GROUP_RATES) * (3(SS)*2(GI)*3(BW)), i.e. 130 + 180 entries.

2014-10-20mac80211: minstrels: fix buffer overflow in HT debugfs rc_statsKarl Beldan
ATM an HT rc_stats line is 106 chars. Times 8(MCS_GROUP_RATES)*3(SS)*2(GI)*2(BW) + CCK(4), i.e. x100, this is well above the current 8192 - sizeof(*ms) currently allocated.

2014-10-14mac80211: fix typo in starting baserate for rts_cts_rate_idxKarl Beldan
It affects non-(V)HT rates and can lead to selecting an rts_cts rate that is not a basic rate or way superior to the reference rate (ATM rates[0] used for the 1st attempt of the protected frame data). E.g, assuming drivers register growing (bitrate) sorted tables of ieee80211_rate-s, having : - rates[0].idx == d'2 and basic_rates == b'10100 will select rts_cts idx b'10011 & ~d'(BIT(2)-1), i.e. 1, likewise - rates[0].idx == d'2 and basic_rates == b'10001 will select rts_cts idx b'10000 The first is not a basic rate and the second is > rates[0]. Also, wrt severity of the addressed misbehavior, ATM we only have one rts_cts_rate_idx rather than one per rate table entry, so this idx might still point to bitrates > rates[1..MAX_RATES].

2014-09-12mac80211: Resolve sk_refcnt/sk_wmem_alloc issue in wifi ack pathAlexander Duyck
There is a possible issue with the use, or lack thereof of sk_refcnt and sk_wmem_alloc in the wifi ack status functionality. Specifically if a socket were to request acknowledgements, and the socket were to have sk_refcnt drop to 0 resulting in it waiting on sk_wmem_alloc to reach 0 it would be possible to have sock_queue_err_skb orphan the last buffer, resulting in __sk_free being called on the socket. After this the buffer is enqueued on sk_error_queue, however the queue has already been flushed resulting in at least a memory leak, if not a data corruption.

2014-09-08mac80211: support DTPC IE (from Cisco Client eXtensions)Steinar H. Gunderson
Linux already supports 802.11h, where the access point can tell the client to reduce its transmission power. However, 802.11h is only defined for 5 GHz, where the need for this is much smaller than on 2.4 GHz. Cisco has their own solution, called DTPC (Dynamic Transmit Power Control). Cisco APs on a controller sometimes but not always send 802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support for parsing and honoring the DTPC IE in addition to the 802.11h element (they do not always contain the same limits, so both must be honored); the format is not documented, but very simple. Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet 1142 joined to a Cisco 2504 WLC, by setting various transmit power levels for the given access points and observing the results. The Wireshark 802.11 dissector agrees with the interpretation of the element, except for negative numbers, which seem to never happen anyway. Signed-off-by: Steinar H.

2014-09-05mac80211: use bss_conf->dtim_period instead of conf.ps_dtim_periodEmmanuel Grumbach
sta_set_sinfo is obviously takes data for specific station. This specific station is attached to a specific virtual interface. Hence we should use the dtim_period from this virtual interface rather than the system wide dtim_period.

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211 Johannes Berg <johannes@sipsolutions.net> says: "Here are a few fixes for mac80211. One has been discussed for a while and adds a terminating NUL-byte to the alpha2 sent to userspace, which shouldn't be necessary but since many places treat it as a string we couldn't move to just sending two bytes. In addition to that, we have two VLAN fixes from Felix, a mesh fix, a fix for the recently introduced RX aggregation offload, a revert for a broken patch (that luckily didn't really cause any harm) and a small fix for alignment in debugfs."
