iwlwifi: pcie: compare with number of IRQs requested for, not number of CPUs

2018-05-29T07:40:25+00:00

When there are 16 or more logical CPUs, we request for `IWL_MAX_RX_HW_QUEUES` (16) IRQs only as we limit to that number of IRQs, but later on we compare the number of IRQs returned to nr_online_cpus+2 instead of max_irqs, the latter being what we actually asked for. This ends up setting num_rx_queues to 17 which causes lots of out-of-bounds array accesses later on. Compare to max_irqs instead, and also add an assertion in case num_rx_queues > IWM_MAX_RX_HW_QUEUES.

Revert "rt2800: use TXOP_BACKOFF for probe frames"

2018-05-29T07:39:07+00:00

This reverts commit fb47ada8dc3c30c8e7b415da155742b49536c61e. In some situations when we set TXOP_BACKOFF, the probe frame is not sent at all. What it worse then sending probe frame as part of AMPDU and can degrade 11n performance to 11g rates. Cc: stable@vger.kernel.org Signed-off-by: Stanislaw Gruszka Signed-off-by: Kalle Valo

mac80211_hwsim: Fix radio dump for radio idx 0

2018-05-22T08:24:17+00:00

Since 6335698e24ec11e1324b916177da6721df724dd8 the radio with idx of 0 will not get dumped in HWSIM_CMD_GET_RADIO because of the last_idx checks. Offset cb->args[0] by 1 similarly to what is done in nl80211.c.

Kalle Valo says: ==================== wireless-drivers fixes for 4.17 A few fixes for 4.17 but nothing really special. The new ETSI WMM parameter support for iwlwifi is not technically a bugfix but important for regulatory compliance. iwlwifi * use new ETSI WMM parameters from regulatory database * fix a regression with the older firmware API 31 (eg. 31.560484.0) brcmfmac * fix a double free in nvmam loading fails rtlwifi * yet another fix for ant_sel module parameter ==================== Signed-off-by: David S.

rtlwifi: cleanup 8723be ant_sel definition

2018-04-24T10:15:08+00:00

Some HP laptops have only a single wifi antenna. This would not be a problem except that they were shipped with an incorrectly encoded EFUSE. It should have been possible to open the computer and transfer the antenna connection to the other terminal except that such action might void the warranty, and moving the antenna broke the Windows driver. The fix was to add a module option that would override the EFUSE encoding. That was done with commit c18d8f509571 ("rtlwifi: rtl8723be: Add antenna select module parameter"). There was still a problem with Bluetooth coexistence, which was addressed with commit baa170229095 ("rtlwifi: btcoexist: Implement antenna selection"). There were still problems, thus there were commit 0ff78adeef11 ("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d6226928369 ("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these attempts at fixing the problem, the code is not yet right. A proper fix is important as there are now instances of laptops having RTL8723DE chips with the same problem. The module parameter ant_sel is used to control antenna number and path. At present enum ANT_{X2,X1} is used to define the antenna number, but this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX} to make it more readable. This change showed examples where incorrect values were used. It was also possible to remove a workaround in halbtcoutsrc.c. The experimental results with single antenna connected to specific path are now as follows: ant_sel ANT_MAIN(#1) ANT_AUX(#2) 0 -8 -62 1 -62 -10 2 -6 -60 Signed-off-by: Ping-Ke Shih Fixes: c18d8f509571 ("rtlwifi: rtl8723be: Add antenna select module parameter") Fixes: baa170229095 ("rtlwifi: btcoexist: Implement antenna selection") Fixes: 0ff78adeef11 ("rtlwifi: rtl8723be: fix ant_sel code") Fixes: 6d6226928369 ("rtlwifi: btcoexist: Fix antenna selection code") Cc: Stable # 4.7+ Reviewed-by: Larry Finger Signed-off-by: Kalle Valo

iwlwifi: mvm: fix old scan version sizes

2018-04-24T10:13:08+00:00

When version 8 of the scan command API was introduced, only the size of version 7 was updated, causing older versions of the firmware to throw BAD_COMMAND errors. Calculating the old version based on the size of the latest version got too complicated and the size of the older versions will never change anyway, so it's better to just hardcoded the sizes.
