xtensa/simdisk: Avoid referring to module::args

2026-08-06T11:29:02+00:00

When simdisk support is built as a loadable module, simdisk_param_set_filename() receives a pointer into module::args and stores each filename pointer as is. In preparation for removing module::args, update the simdisk.filename parameter code to copy the provided string. This is somewhat complicated by the fact that simdisk support can also be built-in, in which case the parameters are parsed during early boot before slab is available. In that case, the command line itself is preserved for the lifetime of the kernel, so continue storing the incoming pointer directly. Reviewed-by: Max Filippov Signed-off-by: Petr Pavlu

tty: xtensa/iss: use strnlen to improve iss_console_write

2026-04-30T09:26:48+00:00

Use strnlen() to limit scanning 's' to 'count' bytes. Use the length of 's' to decide if simc_write() should be called instead of dereferencing it first and then calling strlen(). With strnlen(), iss_console_write() is further hardened against callers where 's' is not NUL-terminated.

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

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).
