Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

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

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

net: xilinx: axienet: Use devres for resource management in probe path

2026-01-22T02:57:07Z

Transition axienet_probe() to managed resource allocation using devm_* APIs for network device and clock handling, while improving error paths with dev_err_probe(). This eliminates the need for manual resource cleanup during probe failures and streamlines the remove() function.

net: xilinx: axienet: Fix kernel-doc warnings for missing return descriptions

2025-09-22T23:37:36Z

Add missing "Return:" sections to kernel-doc comments for four functions: - axienet_calc_cr() - axienet_device_reset() - axienet_free_tx_chain() - axienet_dim_coalesce_count_rx() Also standardize the return documentation format by replacing inline "Returns" text with proper "Return:" tags as per kernel documentation guidelines. Fixes below kernel-doc warnings: - Warning: No description found for return value of 'axienet_calc_cr' - Warning: No description found for return value of 'axienet_device_reset' - Warning: No description found for return value of 'axienet_free_tx_chain' - Warning: No description found for return value of 'axienet_dim_coalesce_count_rx' Signed-off-by: Suraj Gupta Link: https://patch.msgid.link/20250919103754.434711-1-suraj.gupta2@amd.com Signed-off-by: Jakub Kicinski

net: xilinx: axienet: Add error handling for RX metadata pointer retrieval

2025-09-04T14:13:08Z

Add proper error checking for dmaengine_desc_get_metadata_ptr() which can return an error pointer and lead to potential crashes or undefined behaviour if the pointer retrieval fails. Properly handle the error by unmapping DMA buffer, freeing the skb and returning early to prevent further processing with invalid data.

net: xilinx: axienet: Fix RX skb ring management in DMAengine mode

2025-08-15T00:38:44Z

Submit multiple descriptors in axienet_rx_cb() to fill Rx skb ring. This ensures the ring "catches up" on previously missed allocations. Increment Rx skb ring head pointer after BD is successfully allocated. Previously, head pointer was incremented before verifying if descriptor is successfully allocated and has valid entries, which could lead to ring state inconsistency if descriptor setup failed. These changes improve reliability by maintaining adequate descriptor availability and ensuring proper ring buffer state management.
