iwlwifi: mvm: Do not require PHY_SKU NVM section for 3168 devices

2020-03-18T06:14:19+00:00

commit a9149d243f259ad8f02b1e23dfe8ba06128f15e1 upstream. The logic for checking required NVM sections was recently fixed in commit b3f20e098293 ("iwlwifi: mvm: fix NVM check for 3168 devices"). However, with that fixed the else is now taken for 3168 devices and within the else clause there is a mandatory check for the PHY_SKU section. This causes the parsing to fail for 3168 devices. The PHY_SKU section is really only mandatory for the IWL_NVM_EXT layout (the phy_sku parameter of iwl_parse_nvm_data is only used when the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section check so that it's only mandatory for IWL_NVM_EXT.

iwlwifi: pcie: fix rb_allocator workqueue allocation

2020-03-05T15:42:12+00:00

commit 8188a18ee2e48c9a7461139838048363bfce3fef upstream We don't handle failures in the rb_allocator workqueue allocation correctly. To fix that, move the code earlier so the cleanup is easier and we don't have to undo all the interrupt allocations in this case.

iwlegacy: ensure loop counter addr does not wrap and cause an infinite loop

2020-02-24T07:34:51+00:00

[ Upstream commit c2f9a4e4a5abfc84c01b738496b3fd2d471e0b18 ] The loop counter addr is a u16 where as the upper limit of the loop is an int. In the unlikely event that the il->cfg->eeprom_size is greater than 64K then we end up with an infinite loop since addr will wrap around an never reach upper loop limit. Fix this by making addr an int.

iwlwifi: don't throw error when trying to remove IGTK

2020-02-11T12:34:07+00:00

commit 197288d5ba8a5289f22d3aeb4fca3824bfd9b4af upstream. The IGTK keys are only removed by mac80211 after it has already removed the AP station. This causes the driver to throw an error because mac80211 is trying to remove the IGTK when the station doesn't exist anymore. The firmware is aware that the station has been removed and can deal with it the next time we try to add an IGTK for a station, so we shouldn't try to remove the key if the station ID is IWL_MVM_INVALID_STA. Do this by removing the check for mvm_sta before calling iwl_mvm_send_sta_igtk() and check return from that function gracefully if the station ID is invalid.

iwlwifi: mvm: fix NVM check for 3168 devices

2020-02-11T12:33:52+00:00

[ Upstream commit b3f20e098293892388d6a0491d6bbb2efb46fbff ] We had a check on !NVM_EXT and then a check for NVM_SDP in the else block of this if. The else block, obviously, could only be reached if using NVM_EXT, so it would never be NVM_SDP. Fix that by checking whether the nvm_type is IWL_NVM instead of checking for !IWL_NVM_EXT to solve this issue. Reported-by: Stefan Sperling Signed-off-by: Luca Coelho Signed-off-by: Sasha Levin
