2022-01-27iwlwifi: mvm: Increase the scan timeout guard to 30 secondsIlan Peer
commit ced50f1133af12f7521bb777fcf4046ca908fb77 upstream. With the introduction of 6GHz channels the scan guard timeout should be adjusted to account for the following extreme case: - All 6GHz channels are scanned passively: 58 channels. - The scan is fragmented with the following parameters: 3 fragments, 95 TUs suspend time, 44 TUs maximal out of channel time. The above would result with scan time of more than 24 seconds. Thus, set the timeout to 30 seconds.

2020-01-29Revert "iwlwifi: mvm: fix scan config command size"Mehmet Akif Tasova
commit 205608749e1ef394f513888091e613c5bfccbcca upstream. Since v5.4-rc1 was released, iwlwifi started throwing errors when scan commands were sent to the firmware with certain devices (depending on the OTP burned in the device, which contains the list of available channels). For instance: iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD This bug was reported in the ArchLinux bug tracker: https://bugs.archlinux.org/task/64703 And also in a specific case in bugzilla, when the lar_disabled option was set: https://bugzilla.kernel.org/show_bug.cgi?id=205193 Revert the commit that introduced this error, by using the number of channels from the OTP instead of the number of channels that is specified in the FW TLV that tells us how many channels it supports. This reverts commit 06eb547c4ae4382e70d556ba213d13c95ca1801b.

The API was reduced to include only knowledge currently needed by the FW scan logic, the rest is legacy. Support the new, reduced version. Using the old API with newer firmwares (starting from iwlwifi-*-50.ucode, which implements and requires the new API version) causes an assertion failure similar to this one: [ 2.854505] iwlwifi 0000:00:14.3: 0x20000038 | BAD_COMMAND Signed-off-by: Ayala Beker <ayala.beker@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-10-08iwlwifi: mvm: use fast balance scan in case of DCM mode with P2P GOAyala Beker
Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec the fw fails to allocate events for the P2P GO dtim due to long passive scan events. Fix this by requesting all scans in this scenario to be fragmented with fast balance scan time settings.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2016-07-06mac80211: Add support for beacon report radio measurementAvraham Stern
Add the following to support beacon report radio measurement with the measurement mode field set to passive or active: 1. Propagate the required scan duration to the device 2. Report the scan start time (in terms of TSF) 3. Report each BSS's detection time (also in terms of TSF) TSF times refer to the BSS that the interface that requested the scan is connected to.

2016-07-06iwlwifi: mvm: change scan timeout to a delayed workLuca Coelho
Some transports may sleep when writing to registers, which is done when calling iwl_force_nmi(). So we can't call iwl_force_nmi() in a timer context. To solve that, convert the scan timeout timer to a delayed work. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
