2023-06-06wifi: iwlwifi: mvm: tell firmware about per-STA MFP enablementJohannes Berg2-0/+11
Indicate to the firmware for each station whether or not MFP is used with this station. Note that we indicate MFP for it before authorized since we don't know yet, and that will make the firmware not handle should-be-protected management frames without being able to check them.

2023-06-06wifi: iwlwifi: mvm: remove warning for beacon filtering errorJohannes Berg1-5/+1
This warning is sometimes happening if we force a FW error while disconnecting, which is annoying but harmless. However, it's also pointless to throw a warning here, since the stack and driver state doesn't really help, so just remove that so the driver will ignore the error if any.

2023-06-06wifi: iwlwifi: mvm: offload BTM response during D3Haim Dreyfuss3-0/+7
There are mainly two types of BTM (BSS Transition Management) requests, recommendations and notifications. For the first type, a response is needed otherwise, most probably the STA will be disconnected. Since we don't want to wake up the host on it, set the BTM to reject offload flag (if the device supports it) and rely on the FW to take care of it. The FW will reject the BTM request and in case the AP sends DEAUTH the FW can wake up the host to let it decide on the next steps.

2023-06-06wifi: iwlwifi: do not log undefined DRAM buffers unnecessarilyBenjamin Berg1-1/+6
DRAM buffers that are not defined in the TLVs (or are unused in the preset) would cause a log message. To avoid confusion, skip processing buffers with an invalid (i.e. uninitialized) DRAM path.

2023-06-06wifi: iwlwifi: mvm: Fix -Warray-bounds bug in iwl_mvm_wait_d3_notif()Gustavo A. R. Silva1-6/+2
kmemdup() at line 2735 is not duplicating enough memory for notif->tid_tear_down and notif->station_id. As it only duplicates 612 bytes: up to offsetofend(struct iwl_wowlan_info_notif, received_beacons), this is the range of [0, 612) bytes. 2735 notif = kmemdup(notif_v1, 2736 offsetofend(struct iwl_wowlan_info_notif, 2737 received_beacons), 2738 GFP_ATOMIC); which evidently does not cover bytes 612 and 613 for members tid_tear_down and station_id in struct iwl_wowlan_info_notif. See below: $ pahole -C iwl_wowlan_info_notif drivers/net/wireless/intel/iwlwifi/mvm/d3.o struct iwl_wowlan_info_notif { struct iwl_wowlan_gtk_status_v3 gtk[2]; /* 0 488 */ /* --- cacheline 7 boundary (448 bytes) was 40 bytes ago --- */ struct iwl_wowlan_igtk_status igtk[2]; /* 488 80 */ /* --- cacheline 8 boundary (512 bytes) was 56 bytes ago --- */ __le64 replay_ctr; /* 568 8 */ /* --- cacheline 9 boundary (576 bytes) --- */ __le16 pattern_number; /* 576 2 */ __le16 reserved1; /* 578 2 */ __le16 qos_seq_ctr[8]; /* 580 16 */ __le32 wakeup_reasons; /* 596 4 */ __le32 num_of_gtk_rekeys; /* 600 4 */ __le32 transmitted_ndps; /* 604 4 */ __le32 received_beacons; /* 608 4 */ u8 tid_tear_down; /* 612 1 */ u8 station_id; /* 613 1 */ u8 reserved2[2]; /* 614 2 */ /* size: 616, cachelines: 10, members: 13 */ /* last cacheline: 40 bytes */ }; Therefore, when the following assignments take place, actually no memory has been allocated for those objects: 2743 notif->tid_tear_down = notif_v1->tid_tear_down; 2744 notif->station_id = notif_v1->station_id; Fix this by allocating space for the whole notif object and zero out the remaining space in memory after member station_id.

The rs_drv_get_rate flow reads the lq_sta to return the optimal rate for tx frames. This read flow is not protected thereby leaving a small window, a few instructions wide, open to contention by an asynchronous rate update.

2023-05-16wifi: iwlwifi: mvm: don't trust firmware n_channelsJohannes Berg1-0/+10
If the firmware sends us a corrupted MCC response with n_channels much larger than the command response can be, we might copy far too much (uninitialized) memory and even crash if the n_channels is large enough to make it run out of the one page allocated for the FW response. Fix that by checking the lengths. Doing a < comparison would be sufficient, but the firmware should be doing it correctly, so check more strictly.

The DBGI dump is (unsurprisingly) of type DBGI, not SRAM. This leads to bad register accesses because the union is built differently, there's no allocation ID, and thus the allocation ID ends up being 0x8000. Note that this was already wrong for DRAM vs. SMEM since they use different parts of the union, but the allocation ID is at the same place, so it worked.
