treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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/iucv: clean up iucv kernel-doc warnings

2026-02-05T04:39:58+00:00

Fix numerous (many) kernel-doc warnings in iucv.[ch]: - convert function documentation comments to a common (kernel-doc) look, even for static functions (without "/**") - use matching parameter and parameter description names - use better wording in function descriptions (Jakub & AI) - remove duplicate kernel-doc comments from the header file (Jakub) Examples: Warning: include/net/iucv/iucv.h:210 missing initial short description on line: * iucv_unregister Warning: include/net/iucv/iucv.h:216 function parameter 'handle' not described in 'iucv_unregister' Warning: include/net/iucv/iucv.h:467 function parameter 'answer' not described in 'iucv_message_send2way' Warning: net/iucv/iucv.c:727 missing initial short description on line: * iucv_cleanup_queue Build-tested with both "make htmldocs" and "make ARCH=s390 defconfig all".

net: Remove KMSG_COMPONENT macro

2025-11-29T03:20:27+00:00

The KMSG_COMPONENT macro is a leftover of the s390 specific "kernel message catalog" from 2008 [1] which never made it upstream. The macro was added to s390 code to allow for an out-of-tree patch which used this to generate unique message ids. Also this out-of-tree patch doesn't exist anymore. The pattern of how the KMSG_COMPONENT macro is used can also be found at some non s390 specific code, for whatever reasons. Besides adding an indirection it is unused. Remove the macro in order to get rid of a pointless indirection. Replace all users with the string it defines. In all cases this leads to a simple replacement like this: - #define KMSG_COMPONENT "af_iucv" - #define pr_fmt(fmt) KMSG_COMPONENT ": " fmt + #define pr_fmt(fmt) "af_iucv: " fmt [1] https://lwn.net/Articles/292650/ Signed-off-by: Heiko Carstens Acked-by: Alexandra Winter Acked-by: Julian Anastasov Acked-by: Sidraya Jayagond Link: https://patch.msgid.link/20251126140705.1944278-1-hca@linux.ibm.com Signed-off-by: Jakub Kicinski

net: Convert proto_ops connect() callbacks to use sockaddr_unsized

2025-11-05T03:10:32+00:00

Update all struct proto_ops connect() callback function prototypes from "struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the compiler about object sizes. Calls into struct proto handlers gain casts that will be removed in the struct proto conversion patch. No binary changes expected.
