This was done entirely with mindless brute force, using git grep -l '\

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: fill in MODULE_DESCRIPTION()s for CAIF

2024-01-05T16:06:35+00:00

W=1 builds now warn if module is built without a MODULE_DESCRIPTION(). Add descriptions to all the CAIF sub-modules. Link: https://lore.kernel.org/r/20240104144855.1320993-1-kuba@kernel.org Signed-off-by: Jakub Kicinski

caif: move from strlcpy with unused retval to strscpy

2022-08-23T00:57:35+00:00

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

net: caif: fix memory leak in caif_device_notify

2021-06-03T22:05:07+00:00

In case of caif_enroll_dev() fail, allocated link_support won't be assigned to the corresponding structure. So simply free allocated pointer in case of error Fixes: 7c18d2205ea7 ("caif: Restructure how link caif link layer enroll") Cc: stable@vger.kernel.org Reported-and-tested-by: syzbot+7ec324747ce876a29db6@syzkaller.appspotmail.com Signed-off-by: Pavel Skripkin Signed-off-by: David S.

caifdevs->list is traversed using list_for_each_entry_rcu() outside an RCU read-side critical section but under the protection of rtnl_mutex.
