ipv4: igmp: get rid of IGMPV3_{QQIC,MRC} and simplify calculation

2026-05-05T02:09:41Z

Get rid of the IGMPV3_MRC macro and use the igmpv3_mrt() API to calculate the Max Resp Time from the Maximum Response Code. Similarly, for IGMPV3_QQIC, use the igmpv3_qqi() API to calculate the Querier's Query Interval from the QQIC field.

tcp: move tp->segs_in and tp->segs_out to tcp_sock_write_txrx group

2026-05-02T00:22:45Z

segs_in is changed for each incoming packet, including ACK packets. segs_out is changed for each outgoing packet, including ACK packets. They belong to tcp_sock_write_txrx group.

net/tcp: Remove tcp_sigpool

2026-04-30T07:38:56Z

tcp_sigpool is no longer used. It existed only as a workaround for issues in the design of the crypto_ahash API, which have been avoided by switching to the much easier-to-use library APIs instead. Remove it. Reviewed-by: Ard Biesheuvel Signed-off-by: Eric Biggers Link: https://patch.msgid.link/20260427172727.9310-6-ebiggers@kernel.org Signed-off-by: Paolo Abeni

net/tcp-ao: Return void from functions that can no longer fail

2026-04-30T07:38:56Z

Since tcp-ao now uses the crypto library API instead of crypto_ahash, and MACs and keys now have a statically-known maximum size, many tcp-ao functions can no longer fail. Propagate this change up into the return types of various functions.

net/tcp-ao: Use stack-allocated MAC and traffic_key buffers

2026-04-30T07:38:56Z

Now that the maximum MAC and traffic key lengths are statically-known small values, allocate MACs and traffic keys on the stack instead of with kmalloc. This eliminates multiple failure-prone GFP_ATOMIC allocations. Note that some cases such as tcp_ao_prepare_reset() are left unchanged for now since they would require slightly wider changes.
