wifi: iwlwifi: fw: increase fw_version string size In reality 64 bytes are enough to hold fw version string, but some compilers can complain (with W=1) that output may be truncated when building this string with snprintf. Increase the size to avoid this sort of warnings and state explicitely that we want the size to be trancated to 32 bytes.

iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_id 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 <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Link: https://lore.kernel.org/r/iwlwifi.20220128153014.c4ac213cef5c.I6fd9a4fcbcf16ef3a3ae20a2b08ee54ebe06f96f@changeid Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

iwlwifi: fw dump: add infrastructure for dump scrubbing In firmware dumps, currently all kinds of key material may be included, e.g. in host commands (if firmware crashes during the processing of a key-related command) or in the TX FIFO(s) if we have been using in-TX-command key material. Additionally, some firmware versions will advertise sections of their internal data to not dump, due to them containing some sensitive data. Add some infrastructure to allow scrubbing this data out, as dependent on the opmode's idea of what will need to be done.

iwlwifi: incorporate firmware filename into version We have many different firmware images with the same version, and it's sometimes cumbersome to figure out which image was really used, especially as the marketing strings that we do print out can be the same for (slightly) different hardware using different firmware images. Incorporate the firmware filename into the fw_version so it's printed out all the time. Unfortunately, this will make the string be longer than the 32 characters for ethtool, but we almost never really use ethtool, so strip the "iwlwifi-" prefix (if not overridden), and the remaining data that may then be stripped at the end is not usually useful anyway.

The first byte of the field indicates the driver to override existing configuration or keep the previous one The second byte of the field indicated the driver to replace the regions of the previous trigger or to append new regions to it. Change the way the active triggers are maintained to support trigger override in different apply points. Do this by making a trigger that updates at runtime by the triggers that are being used in the different apply points. In case of an assert, the driver does not reconfigure the triggers and uses the old configuration which leads to undefined behavior. Solve this by clearing the triggers in assert recovery flow.

iwlwifi: dbg_ini: remove redundant dram buffer allocation There are several flows in that can cause redundant allocation. In case the driver reaches the maximum amount of blocks allowed, it allocates the buffer and only then checks if it reached the maximum amount of blocks and return without freeing the buffer, causing a memory leak. Solve this by moving the check of the amount of buffers being used before the allocation. In case there was an assert, the apply points are being reused, causing that for each assert, the driver allocates a new redundant buffer. Solve this by adding a new is_alloc field to indicate if the driver already allocated memory for the requested buffer. Also, split iwl_fw_dbg_buffer_allocation function into iwl_fw_dbg_buffer_allocation and iwl_fw_dbg_buffer_apply to increase the clearity of the flow.
