2022-06-20wifi: mac80211: move interface config to new structJohannes Berg1-6/+6
We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif. Some adjustments were done with the following spatch: @@ expression sdata; struct ieee80211_vif *vifp; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ ( -sdata->vif.bss_conf.var +sdata->vif.cfg.var | -vifp->bss_conf.var +vifp->cfg.var ) @bss_conf@ struct ieee80211_bss_conf *bss_conf; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ -bss_conf->var +vif_cfg->var (though more manual fixups were needed, e.g. replacing "vif_cfg->" by "vif->cfg." in many files.)

2022-05-18iwlwifi: mvm: always tell the firmware to accept MCAST frames in BSSEmmanuel Grumbach1-7/+6
Make the firmware's life easier and always accept MCAST frames. If needed, drop them in the driver. We need to filter out MCAST frames in order not to have false positives in the decryption check. If we accept MCAST frames before we have the GKT installed, we'll end up complaining that we can't decrypt the frame. Implement the same filtering, but in the driver.

2022-02-18iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_idJohannes Berg1-8/+5
Instead of taking the group/command separately, make the function take a combined command ID. In many cases, this allows us to pass an existing command ID (e.g. cmd.id), or introduce a new variable for it, so that we don't use the command ID twice. This way, we can also use LONG_GROUP implicitly, so we don't need to spell that out for many commands. Apart from mvm.h, fw/img.{c,h} changes and some copyright and indentation updates, this was done with spatch: @@ identifier cmd; expression fw, G, C, def; @@ struct iwl_host_cmd cmd = { .id = WIDE_ID(G, C), ... }; ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier cmd; expression fw, C, def; @@ struct iwl_host_cmd cmd = { .id = C, ... }; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = WIDE_ID(G, C); ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, WIDE_ID(G, C), flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = C; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, C, flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ expression fw, C, def; @@ -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, C, def) @@ expression fw, C, G, def; @@ -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, WIDE_ID(G, C), def) Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]> Link: https://lore.kernel.org/r/iwlwifi.20220128153014.c4ac213cef5c.I6fd9a4fcbcf16ef3a3ae20a2b08ee54ebe06f96f@changeid Signed-off-by: Luca Coelho <[email protected]>

2021-02-05iwlwifi: mvm: add notification size checksJohannes Berg1-9/+9
We shouldn't trust the firmware with the sizes (or contents) of notifications, accessing too much data could cause page faults if the data doesn't fit into the allocated space. This applies more on older NICs where multiple notifications can be in a single RX buffer. Add a general framework for checking a minimum size of any notification in the RX handlers and use it for most. Some RX handlers were already checking and I've moved the checks, some more complex checks I left and made them _NO_SIZE for the RX handlers.

2019-02-04iwlwifi: mvm: config mac ctxt to HE before TLCLiad Kaufman1-2/+1
If we have a station connecting HE, make sure that the MAC ctxt is updated with indication of this before setting the TLC rates via the TLC manager command. Signed-off-by: Liad Kaufman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-04iwlwifi: mvm: support new format for the beacon notificationEmmanuel Grumbach1-12/+23
The firmware is changing the format of the beacon notification to remove the dependency on the Tx response format. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-04iwlwifi: mvm: support CHANNEL_SWITCH_TIME_EVENT_CMD commandSara Sharon1-21/+37
When we do channel switch, we used to schedule time events ourselves. This was offloaded to FW. Support the new command and flow. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-01-29iwlwifi: mvm: Disconnect on large beacon lossAndrei Otcheretianski1-2/+3
Some buggy APs stop sending beacons, but continue to ack our null data packets or even run some traffic. It's better not to stick connected to such an AP forever, so disconnect after some larger beacon loss threshold is crossed.

2019-01-29iwlwifi: mvm: add an option to dereference vif by idSara Sharon1-55/+44
Currently whenever we get firmware notification with mac id, we iterate over all the interfaces to find the ID. This is a bit cumbersome. Instead, adding an array of RCU pointers, like we have for station IDs. This is not expensive space wise since we have only up to 4 active MACs, and not complicated code wise, since we have a clear point to init and de-init it.

2019-01-29iwlwifi: mvm: fix %16 to %016 print formatJohannes Berg1-1/+1
With just %16, it means 16 characters padding, but we really don't want to print "0x 1F4547B", but instead want to have this filled with zeroes, so we need the 0. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-01-25iwlwifi: mvm: Do not set RTS/CTS protection for P2P Device MACIlan Peer1-2/+0
As this is not needed and might cause interoperability issues during pairing with devices that would not reply to RTS frames. Signed-off-by: Ilan Peer <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-01-25iwlwifi: mvm: support mac80211 TXQs modelSara Sharon1-71/+1
Move to use the new mac80211 TXQs implementation. This has quite a few benefits for us. We can get rid of the awkward mapping of DQA to mac80211 queues. We can stop buffering traffic while waiting for the queue to be allocated. We can also use mac80211 AMSDUs instead of building it ourselves. The usage is pretty simple: Each ieee80211_txq contains iwl_mvm_txq. There is such a queue for each TID, and one for management frames. We keep having static AP queues for probes and non-bufferable MMPDUs, along with broadcast and multicast queues. Those are being used from the "old" TX invocation path - iwl_mvm_mac_tx. When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is being called, and either invokes the TX path, or allocates the queue if it does not exist. Most of the TX path is left untouched, although we can consider cleaning it up some more, for example get rid of the duplication of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.
