      iwlagn: use cts-to-self protection on 5000 adapters series · 42b70a5f
      Stanislaw Gruszka 提交于
      This patch fixes 802.11n stability and performance regression we have
      since 2.6.35. It boost performance on my 5GHz N-only network from about
      5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.
      
      These are test results of 5x downloading of approximately 700MB iso
      image:
      
      vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
      patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946
      
      This was achieved with NetworkManager configured to do not perform
      periodical scans, by configuring constant BSSID. With periodical scans,
      after some time, performance downgrade to unpatched driver level, like
      in example below:
      
      patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683
      
      However patch still make better here, since similar test on unpatched
      driver make link disconnects with below messages after some time:
      
      wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
      wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
      wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
      wlan1: authentication with 00:23:69:35:d1:3f timed out
      
      On 2.6.35 kernel patch helps against connection hangs with messages:
      
      iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
      iwlagn 0000:20:00.0: On demand firmware reload
      iwlagn 0000:20:00.0: Stopping AGG while state not ON or starting

      iwlwifi: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning · 805d7d23
      Stephen Boyd 提交于
      Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following
      warning:
      
      In file included from arch/x86/include/asm/uaccess.h:573,

                       from drivers/net/wireless/iwlwifi/iwl-agn-rs.c:28:

      attribute warning: copy_from_user() buffer size is not provably
      correct
      
      presumably due to buf_size being signed causing GCC to fail to
      see that buf_size can't become negative.
