2010-08-24iwlwifi: configurable ampdu factor and densityWey-Yi Guy
Add ampdu factor and density to .cfg, this allow both parameters can be configure per device based. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlwifi: more generic name for rssi calc in iwlagnWey-Yi Guy
Change the define to more generic naming to match _agn devices since the rssi calculation are common function for 5000 series and up Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlwifi: additional parameter in REPLY_RX_PHY_CMDWey-Yi Guy
Adding additional parameter in REPLY_RX_PHY_CMD, frame_time indicate the frame's time on the air based on byte count and frame rate calculation Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlagn: continue perform rate scale when error detectedWey-Yi Guy
If for some reason, the actual link command not matching neither active nor search table; instead of return and not performing rate scale, by-pass the data collection and continue the rate scale process. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlagn: adjust starting action for rate scaleWey-Yi Guy
During rate scale, reset starting action after making action adjustment to avoid the possibility of break out of loop too early. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlwifi: refactor iwl_setup_rxon_timingJohannes Berg
All callers of iwl_setup_rxon_timing() also send the command right away, so rename the function to iwl_send_rxon_timing() and move the sending into it. Also, some callers clear the data, this can be done always and thus moved in as well. Finally, there's no reason for the function to acquire the spinlock, but it should be called with the mutex held, so assert that.

2010-08-24iwlwifi: cleanup iwl_set_rxon_channel()Shanyu Zhao
Update outdated comments of iwl_set_rxon_channel() to reflect the current signature. Also remove the unnecessary validation of the channel. Those channel info are constructed in iwlwifi driver and mac80211 will never modify the content of the struct. Also everytime before this function is called the channel info has been validated already (as a paranoid check).

2010-08-24iwlwifi: avoid race condition in channel changeShanyu Zhao
When iwl_mac_config() is called by mac80211, the channel pointer hw->conf->channel can potentially change, resulting in mismatch band and channel number when configuring RXON command. To avoid this situation, save the channel pointer in local variables and validate the channel before using it. Note that priv->mutex is locked during the whole function so the local variables are safe. Same change is applied to iwl_mac_channel_switch() since basically it copies code from iwl_mac_config(). Also removed an outdated comment in the flow. Signed-off-by: Shanyu Zhao <shanyu.zhao@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-24iwlwifi: do not call ieee80211_frequency_to_channelShanyu Zhao
A few cases in iwlwifi driver function ieee80211_frequency_to_channel() is called to get channel number from center frequency. This is not needed since the channel number is already saved in hw_value field of struct ieee80211_channel in function iwlcore_init_geos(). So replace those function calls with hw_value field of struct ieee80211_channel.

It will not look standard-compliant in a sniffer because because it doesn't * sync TSF * adjust the TSF in beacons * send beacons at TBTT * cancel beacons when another phy sends However, it does allow testing the configuration and parts of the mac80211 code for IBSS and as such is still useful.

2010-08-24wireless: move documentation booksJohannes Berg
This moves mac80211 documentation into a new 802.11 bookset and also adds a cfg80211 book to the set.

2010-08-24p54: improve eeprom parserChristian Lamparter
Like other vendors, p54* devices have a checksum for the EEPROM descriptor data. This patch enhances the parser code to generate and verify the data fields, before initializing the radio-chip on the card. Note: If you have to bootstrap an alternative EEPROM image for your device and you don't know how to generate a valid crc ccitt checksum, you should take a look at: http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git The "checksum" utility loads a binary p54 EEPROM blob (use the -f switch, to skip the check) and applies the correct crc automatically.

2010-08-24ath5k: remove monitor check in receive_frame_ok filterBob Copeland
Monitor interfaces are never seen by the driver, so tests based on that opmode don't make sense. Also, we already pass all mic failure packets.

Allow userspace to register for more than just action frames by giving the frame subtype, and make it possible to use this in various modes as well.

2010-08-24mac80211: remove unused don't-encrypt flagJohannes Berg
When MFP is disabled, action frames will not be encrypted since they are management frames and the only management frames that can then be encrypted are authentication frames.

2010-08-24cfg80211: mark ieee80211_hdrlen constJohannes Berg
This function analyses only its single, value-passed argument, and has no side effects. Thus it can be const, which makes mac80211 smaller, for example: text data bss dec hex filename 362518 16720 884 380122 5ccda mac80211.ko (before) 362358 16720 884 379962 5cc3a mac80211.ko (after) a 160 byte saving in text size, and an optimisation because the function won't be called as often.

2010-08-23net: increase the size of priv_flags and add IFF_OVS_DATAPATHSimon Horman
IFF_OVS_DATAPATH is a place-holder for the Open vSwitch datapath which I am preparing to submit for merging. As all 16 bits of priv_flags are already assigned flags, also increase the size of priv_flags to 32 bits. Unfortunately, by my calculations this increases the size of struct net_device by 4 bytes on 32bit architectures and 8 bytes on 64 bit architectures. I couldn't see an obvious way to avoid that.

2010-08-23ethtool: allow non-netadmin to query settingsstephen hemminger
The SNMP daemon uses ethtool to determine the speed of network interfaces. This fails on Debian (and probably elsewhere) because for security SNMP daemon runs as non-root user (snmp). Note: A similar patch was rejected previously because of a concern about the possibility that on some hardware querying the ethtool settings requires access to the PHY and could slow the machine down. But the security risk of requiring SNMP daemon (and related services) to run as root far out weighs the risk of denial-of-service.

2010-08-23dccp ccid-2: Replace broken RTT estimator with better algorithmGerrit Renker
The current CCID-2 RTT estimator code is in parts broken and lags behind the suggestions in RFC2988 of using scaled variants for SRTT/RTTVAR. That code is replaced by the present patch, which reuses the Linux TCP RTT estimator code. Further details: ---------------- 1. The minimum RTO of previously one second has been replaced with TCP's, since RFC4341, sec. 5 says that the minimum of 1 sec. (suggested in RFC2988, 2.4) is not necessary. Instead, the TCP_RTO_MIN is used, which agrees with DCCP's concept of a default RTT (RFC 4340, 3.4). 2. The maximum RTO has been set to DCCP_RTO_MAX (64 sec), which agrees with RFC2988, (2.5). 3. De-inlined the function ccid2_new_ack(). 4. Added a FIXME: the RTT is sampled several times per Ack Vector, which will give the wrong estimate. It should be replaced with one sample per Ack. However, at the moment this can not be resolved easily, since - it depends on TX history code (which also needs some work), - the cleanest solution is not to use the `sent' time at all (saves 4 bytes per entry) and use DCCP timestamps / elapsed time to estimated the RTT, which however is non-trivial to get right (but needs to be done). Reasons for reusing the Linux TCP estimator algorithm: ------------------------------------------------------ Some time was spent to find a better alternative, using basic RFC2988 as a first step. Further analysis and experimentation showed that the Linux TCP RTO estimator is superior to a basic RFC2988 implementation. A summary is on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/ccid2/rto_estimator/ In addition, this estimator fared well in a recent empirical evaluation: Rewaskar, Sushant, Jasleen Kaur and F. Donelson Smith. A Performance Study of Loss Detection/Recovery in Real-world TCP Implementations. Proceedings of 15th IEEE International Conference on Network Protocols (ICNP-07), 2007. Thus there is significant benefit in reusing the existing TCP code. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
