This function puts a fairly large structure unnecessarily on the stack, and also has a few other very strange things, clean it up a bit. Signed-off-by:

If the device is malfunctioning and reports too short rx descriptor length, iwl_rx_packet_payload_len() will underflow, eventually resulting in accessing memory out of bounds and other bad things. Prevent this. Signed-off-by:

In MCC_UPDATE_CMD we get from the FW the number of entries in the channel info array. We used to WARN_ON if this parameter is greater than we expected. Since this is not really a driver bug, and since it might happen in some valid cases too, we shouldn't use a warning here. Fix this by replacing the WARN_ON with a debug print. Signed-off-by:

Due to preg protection we cannot write to this register while FW is running (when FW in Halt it is ok). since we have some cases that we need to dump this region while FW is running remove this writing from DRV. FW will do this writing. Signed-off-by:

Since commit a05829a7 ("cfg80211: avoid holding the RTNL when calling the driver") we're not only holding the RTNL when going in and out of suspend, but also the wiphy->mtx. Add that to the D3 test debugfs in iwlwifi since it's required for various calls to mac80211. Fixes: a05829a7 ("cfg80211: avoid holding the RTNL when calling the driver") Signed-off-by:

We may not have all the interfaces added to the driver when we get the THERMAL_DUAL_CHAIN_REQUEST notification from the FW, so instead of iterating all vifs to update SMPS, iterate only the ones that are already assigned. The interfaces that were not assigned yet, will be updated accordingly when we start using them. Signed-off-by:

Until now function just got a pointer to some buffer and used it as if it's good to use with no boundaries about size left in the buffer. This infra helps for internal functions ops to make sure buffer usage is in bound of allocation. We also add external checks with warnings to verify every internal function didn't exceed usage of the free buffer size. Signed-off-by:

Most of this change is a continuation of commit 403ea939 ("iwlwifi: dbg: Mark ucode tlv data as const") propagating the (const) type qualifier for ucode based tlv data to avoid having the impression that it is writeable. The other part of the change preserves the (const) type qualifier over casts and function calls where it was previously lost. Both changes are needed to avoid compile time errors on system with more strict error settings, in this case found with clang on FreeBSD. Sponsored by: The FreeBSD Foundation Signed-off-by:

In order to de-const variables simply casting through (void *) is not enough: "cast from 'const .. *' to 'void *' drops const qualifier". Cast through (uintptr_t) as well [1] to make this compile on systems with more strict requirements. In addition passing const void *data to dma_map_single() also drops the (const) qualifier. De-constify on variable on assignment which may be overwritten later. In either case the (void *) cast to dma_map_single() is not needed (anymore) either.

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: -

The order of arguments for iwl_cmd_id() is confusing, and the version is always 0 and thus a useless argument. Prefer the WIDE_ID() macro (which needs to be a macro due to use in switch cases etc.) over the iwl_cmd_id() function. Obviously done with spatch: @@ expression G, C; @@ -iwl_cmd_id(C, G, 0) +WIDE_ID(G, C) Signed-off-by:

Since FW is now in charge of timing the channel switch, there is no need to send the add/modify/remove time event command to fw with every (e)CSA element. However, the driver needs to cancel the channel switch if the CS start notification arrives and it does not know about an ongoing channel switch. Signed-off-by:

The recent fix for NULL sta in iwl_mvm_get_tx_rate() still has a call of iwl_mvm_sta_from_mac80211() that may be called with NULL sta. Although this practically only points to the address and the actual access doesn't happen due to the conditional evaluation at a later point, it looks a bit flaky. This patch drops the temporary variable above and evaluates iwm_mvm_sta_from_mac80211() directly for avoiding confusions.
