2026-03-25wifi: iwlwifi: pcie: don't dump on reset handshake in dumpJohannes Berg
When a FW dump happens, possibly even because of a reset handshake timeout, there's no point in attempting to dump again. Since all the callers of the function outside the transport itself are from the FW dump infrastructure, just split the internal function and make the external one not dump on timeout.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
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>
2026-01-05compiler-context-analysis: Remove __cond_lock() function-like helperMarco Elver
As discussed in [1], removing __cond_lock() will improve the readability of trylock code. Now that Sparse context tracking support has been removed, we can also remove __cond_lock(). Change existing APIs to either drop __cond_lock() completely, or make use of the __cond_acquires() function attribute instead. In particular, spinlock and rwlock implementations required switching over to inline helpers rather than statement-expressions for their trylock_* variants.

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.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally.

So, we add iwl_tx_cmd_v6_params, that will contain everything except the flexible array and use this one for the containing structs. Also, as part of the refactoring remove unused flex array `payload`.

The conversion from compiler assisted indexing to manual indexing wasn't done correctly.

2025-07-09wifi: iwlwifi: match discrete/integrated to fix some namesJohannes Berg
Some device names were wrong because our internal data suggested that discrete Ga devices have B-step RF, when they actually have C-step. However, matching the step for them is bad anyway. Change the code to be able to find the devinfo depending on the device being integrated or discrete. This is only for the names, since the RF config cannot be different for the same RF because it's discrete or integrated, so add a kunit test that ensures both (a) the RF config is the same and (b) the name is different (the latter really only because that's the whole point of having a match on the discrete/integrated bit.) Remove the RF step matching since it's no longer needed now.

We needed it for setting up trans parameters that could change later in the probe flow.
