2026-02-21Convert 'alloc_flex' family to use the new default GFP_KERNEL argumentLinus Torvalds
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>
2025-09-09wifi: iwlwifi: pcie: move pm_support to the specific transportMiri Korenblit
Currently it is under iwl_trans, which is the bus agnostic part of the transport. But really it is relevant for pcie only, so move it to the iwl_trans_pcie and export it via an API to the opmode.

2025-08-28wifi: iwlwifi: simplify iwl_trans_pcie_d3_resumeMiri Korenblit
If iwl_trans_d3_resume succeeded but the hw requested a reset, this will be indicated to the opmode via the iwl_d3_status parameter while the return value will be 0. But the opmode doesn't really care if the resume failed or if a restart is required. It acts the same in both cases (beside different logs, but this can be done in iwl_trans_pcie_d3_resume) This complicates the code for no good reason. Change the iwl_trans_pcie_d3_resume to return an error value also in the case that everything went successfully but a restart is required, and add more logs so we can differentiate between the cases. This makes iwl_d3_status redundant. Remove it as well.

2025-06-24wifi: cfg80211/mac80211: Add support to get radio indexRoopni Devanathan
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

Currently, in supporting API's to fill sinfo structure from sta structure, is mapped to fill the fields from sta->deflink. However, for multi-link (ML) station, sinfo structure should be filled from corresponding link_id. Therefore, add link_id as an additional argument in supporting API's for filling sinfo structure correctly. Link_id is set to -1 for non-ML station and corresponding link_id for ML stations. In supporting API's for filling sinfo structure, check for link_id, if link_id < 0, fill the sinfo structure from sta->deflink, otherwise fill from sta->link[link_id]. Current, changes are done at the deflink level i.e, pass -1 as link_id. Actual link_id will be added in subsequent patches to support station statistics for MLO.

2025-03-18wifi: iwlwifi: dvm: Avoid -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `__struct_group()` helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure groups together all the members of the flexible `struct iwl_tx_cmd` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct members currently causing trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct iwl_tx_cmd_hdr` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. So, with these changes, fix the following warnings: drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2426:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-01-13wifi: iwlwifi: rework firmware error handlingJohannes Berg
In order to later add the ability to do deeper resets of the device when it crashes, first restructure the firmware error handling. Instead of having just a single nic_error() method that handles all, split it: - nic_error() just handles and prints the error itself, - dump_error() synchronously creates an error dump, and - sw_reset() will be called to request doing a SW reset. This changes the architecture so that the transport is now responsible for deciding how to do the reset, and therefore the handling of reprobe if error occurs during reconfig moves there, which necessitates adding a method there that notifies the transport that the recovery was completed. Actually introducing the model under which deeper resets can be done will be in future patches.

2025-01-13wifi: iwlwifi: unify cmd_queue_full() into nic_error()Johannes Berg
Except for some special handling in DVM, error dump and some message behaviour, cmd_queue_full and nic_error are equivalent now. Unify by giving a special error type, so DVM can continue to differentiate.

2025-01-13wifi: iwlwifi: differentiate NIC error typesJohannes Berg
Instead of differentiating only sync/async, differentiate the type of error, and document that only reset handshake timeout (IWL_ERR_TYPE_RESET_HS_TIMEOUT) needs sync handling. The special sync handling is somewhat temporary, the idea is to later split the nic_error() method into error dump, synchronizing the dump, and SW reset methods, and the type is mostly in order to unify command queue full handling into that new architecture as well.

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

This was needed when we had multiple types of transports. Now we only have pcie, so there is no need for this ops. Cleanup the code such as the different trans APIs will call the pcie function directly, instead of calling the callback, and remove struct iwl_trans_ops.
