2026-04-22bnge: remove unsupported backing store typeVikas Gupta1-16/+0
The backing store type, BNGE_CTX_MRAV, is not applicable in Thor Ultra devices. Remove it from the backing store configuration, as the firmware will not populate entities in this backing store type, due to which the driver load fails.

2026-04-13bnge: return after auxiliary_device_uninit() in error pathGreg Kroah-Hartman1-0/+1
When auxiliary_device_add() fails, the error block calls auxiliary_device_uninit() but does not return. The uninit drops the last reference and synchronously runs bnge_aux_dev_release(), which sets bd->auxr_dev = NULL and frees the underlying object. The subsequent bd->auxr_dev->net = bd->netdev then dereferences NULL, which is not a good thing to have happen when trying to clean up from an error. Add the missing return, as the auxiliary bus documentation states is a requirement (seems that LLM tools read documentation better than humans do...)

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds2-14/+7
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 Torvalds6-14/+14
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 Cook6-33/+29
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>
