drivers: net: drop ipv6_stub usage and use direct function calls

2026-03-29T18:21:23Z

As IPv6 is built-in only, the ipv6_stub infrastructure is no longer necessary. Convert all drivers currently utilizing ipv6_stub to make direct function calls. The fallback functions introduced previously will prevent linkage errors when CONFIG_IPV6 is disabled. Signed-off-by: Fernando Fernandez Mancera Tested-by: Ricardo B. Marlière Reviewed-by: Jason A.

ovpn: consolidate crypto allocations in one chunk

2026-03-17T10:09:20Z

Currently ovpn uses three separate dynamically allocated structures to set up cryptographic operations for both encryption and decryption. This adds overhead to performance-critical paths and contribute to memory fragmentation. This commit consolidates those allocations into a single temporary blob, similar to what esp_alloc_tmp() does. The resulting performance gain is +7.7% and +4.3% for UDP when using AES and ChaChaPoly respectively, and +4.3% for TCP.

ovpn: add support for asymmetric peer IDs

2026-03-17T10:09:05Z

In order to support the multipeer architecture, upon connection setup each side of a tunnel advertises a unique ID that the other side must include in packets sent to them. Therefore when transmitting a packet, a peer inserts the recipient's advertised ID for that specific tunnel into the peer ID field. When receiving a packet, a peer expects to find its own unique receive ID for that specific tunnel in the peer ID field. Add support for the TX peer ID and embed it into transmitting packets. If no TX peer ID is specified, fallback to using the same peer ID both for RX and TX in order to be compatible with the non-multipeer compliant peers.

ovpn: use correct array size to parse nested attributes in ovpn_nl_key_swap_doit

2026-03-17T10:08:54Z

In ovpn_nl_key_swap_doit, the attributes array used to parse the OVPN_A_KEYCONF uses OVPN_A_PEER_MAX instead of OVPN_A_KEYCONF_MAX. Note that this does not cause any bug, since currently OVPN_A_KEYCONF_MAX < OVPN_A_PEER_MAX. The wrong constant was introduced by commit 203e2bf55990 ("ovpn: implement key add/get/del/swap via netlink") Signed-off-by: Sabrina Dubroca Signed-off-by: Antonio Quartulli

net: remove addr_len argument of recvmsg() handlers

Use msg->msg_namelen as a place holder instead of a temporary variable, notably in inet[6]_recvmsg().

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
