There is no need to compare *val.vu32* with < 0 because such variable is of type u32 (32 bits, unsigned), making it impossible to hold a negative value. Fix this by removing such comparison. Also, initialize variable *max_val* to -1, just in case it is not initialized to either BNXT_MSIX_VEC_MAX or BNXT_MSIX_VEC_MIN_MAX before using it in a comparison with val.vu32 at line 159: if (val.vu32 > max_val) Addresses-Coverity-ID: 1473915 ("Unsigned compared against 0") Addresses-Coverity-ID: 1473920 ("Uninitialized scalar variable") Signed-off-by: Gustavo A.

Sara Sharon authored
iwl_fw_dbg_collect can be called by any function that already has the error string ready. iwl_fw_dbg_collect_trig, on the other hand, does string formatting. The occurrences decrement is at iwl_fw_dbg_collect_trig, instead of iwl_fw_dbg_collect, which causes it to sometimes be skipped. Move it to the right location.

For trigger-based PPDUs, most values aren't part of the HE-SIG-A because they're preconfigured by the trigger frame. However, we still have this information since we used the trigger frame to configure the hardware, so we can (and do) read it back out and can thus show it in radiotap.

With NICs that don't read the NVM directly and instead rely on getting the relevant data from the firmware, the number of reserved MAC addresses was not added to the API. This caused the driver to assume there is only one address which results in all interfaces getting the same address. Update the API to fix this. While at it, fix-up the comments with firmware api names to actually match what we have in the firmware.

If all free RB queues are empty, the driver will never restock the free RB queue. That's because the restocking happens in the Rx flow, and if the free queue is empty there will be no Rx. Although there's a background worker (a.k.a. allocator) allocating memory for RBs so that the Rx handler can restock them, the worker may run only after the free queue has become empty (and then it is too late for restocking as explained above). There is a solution for that called 'emergency': If the number of used RB's reaches half the amount of all RB's, the Rx handler will not wait for the allocator but immediately allocate memory for the used RB's and restock the free queue. But, since the used RB's is per queue, it may happen that the used RB's are spread between the queues such that the emergency check will fail for each of the queues (and still run out of RBs, causing the above symptom). To fix it, move to emergency mode if the sum of *all* used RBs (for all Rx queues) reaches half the amount of all RB's Signed-off-by: Shaul Triebitz <shaul.triebitz@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

Fix a bug that happens in the following scenario: 1) suspend without WoWLAN 2) mac80211 calls drv_stop because of the suspend 3) __iwl_mvm_mac_stop deallocates the aux station 4) during drv_stop the firmware crashes 5) iwlmvm: * sets IWL_MVM_STATUS_HW_RESTART_REQUESTED * asks mac80211 to kick the restart flow 6) mac80211 puts the restart worker into a freezable queue which means that the worker will not run for now since the workqueue is already frozen 7) ... 8) resume 9) mac80211 runs ieee80211_reconfig as part of the resume 10) mac80211 detects that a restart flow has been requested and that we are now resuming from suspend and cancels the restart worker 11) mac80211 calls drv_start() 12) __iwl_mvm_mac_start checks that IWL_MVM_STATUS_HW_RESTART_REQUESTED clears it, sets IWL_MVM_STATUS_IN_HW_RESTART and calls iwl_mvm_restart_cleanup() 13) iwl_fw_error_dump gets called and accesses the device to get debug data 14) iwl_mvm_up adds the aux station 15) iwl_mvm_add_aux_sta() allocates an internal station for the aux station 16) iwl_mvm_allocate_int_sta() tests IWL_MVM_STATUS_IN_HW_RESTART and doesn't really allocate a station ID for the aux station 17) a new queue is added for the aux station Note that steps from 5 to 9 aren't really part of the problem but were described for the sake of completeness. Once the iwl_mvm_mac_stop() is called, the device is not accessible, meaning that step 12) can't succeed and we'll see the following: drivers/net/wireless/intel/iwlwifi/pcie/trans.c:2122 iwl_trans_pcie_grab_nic_access+0xc0/0x1d6 [iwlwifi]() Timeout waiting for hardware access (CSR_GP_CNTRL 0x080403d8) Call Trace: [<ffffffffc03e6ad3>] iwl_trans_pcie_grab_nic_access+0xc0/0x1d6 [iwlwifi] [<ffffffffc03e6a13>] iwl_trans_pcie_dump_regs+0x3fd/0x3fd [iwlwifi] [<ffffffffc03dad42>] iwl_fw_error_dump+0x4f5/0xe8b [iwlwifi] [<ffffffffc04bd43e>] __iwl_mvm_mac_start+0x5a/0x21a [iwlmvm] [<ffffffffc04bd6d2>] iwl_mvm_mac_start+0xd4/0x103 [iwlmvm] [<ffffffffc042d378>] drv_start+0xa1/0xc5 [iwl7000_mac80211] [<ffffffffc045a339>] ieee80211_reconfig+0x145/0xf50 [mac80211] [<ffffffffc044788b>] ieee80211_resume+0x62/0x66 [mac80211] [<ffffffffc0366c5b>] wiphy_resume+0xa9/0xc6 [cfg80211] The station id of the aux station is set to 0xff in step 3 and because we don't really allocate a new station id for the auxliary station (as explained in 16), we end up sending a command to the firmware asking to connect the queue to station id 0xff. This makes the firmware crash with the following information: 0x00002093 | ADVANCED_SYSASSERT 0x000002F0 | trm_hw_status0 0x00000000 | trm_hw_status1 0x00000B38 | branchlink2 0x0001978C | interruptlink1 0x00000000 | interruptlink2 0xFF080501 | data1 0xDEADBEEF | data2 0xDEADBEEF | data3 Firmware error during reconfiguration - reprobe! FW error in SYNC CMD SCD_QUEUE_CFG Fix this by clearing IWL_MVM_STATUS_HW_RESTART_REQUESTED in iwl_mvm_mac_stop(). We won't be able to collect debug data anyway and when we will brought up again, we will have a clean state from the firmware perspective. Since we won't have IWL_MVM_STATUS_IN_HW_RESTART set in step 12) we won't get to the 2093 ASSERT either.
