While looking at TC_ACT_* handling, the TC_ACT_CONSUMED is only handled in
sch_handle_ingress but not sch_handle_egress. This was added via cd11b164073b
("net/tc: introduce TC_ACT_REINSERT.") and e5cf1baf92cb ("act_mirred: use
TC_ACT_REINSERT when possible") and later got renamed into TC_ACT_CONSUMED
via 720f22fed81b ("net: sched: refactor reinsert action").
The initial work was targeted for ovs back then and only needed on ingress,
and the mirred action module also restricts it to only that. However, given
it's an API contract it would still make sense to make this consistent to
sch_handle_ingress and handle it on egress side in the same way, that is,
setting return code to "success" and returning NULL back to the caller as
otherwise an action module sitting on egress returning TC_ACT_CONSUMED could
lead to an UAF when untreated.

After the fix, there are no kmemleak reports with the reproducer. This is
in line with what is also done on the ingress side, and from debugging the
skb_unref(skb) on dummy xmit and sch_handle_egress() side, it is visible
that these are two different skbs with both skb_unref(skb) as true. The two
seen skbs are due to mirred doing a skb_clone() internally as use_reinsert
is false in tcf_mirred_act() for egress. This was initially reported by Gal.

tls: expand tls_cipher_size_desc to simplify getsockopt/setsockopt
Commit 2d2c5ea24243 ("net/tls: Describe ciphers sizes by const
structs") introduced tls_cipher_size_desc to describe the size of the
fields of the per-cipher crypto_info structs, and commit ea7a9d88ba21
("net/tls: Use cipher sizes structs") used it, but only in
tls_device.c and tls_device_fallback.c, and skipped converting similar
code in tls_main.c and tls_sw.c.
This series expands tls_cipher_size_desc (renamed to tls_cipher_desc
to better fit this expansion) to fully describe a cipher:
- offset of the fields within the per-cipher crypto_info
- size of the full struct (for copies to/from userspace)
- offload flag
- algorithm name used by SW crypto
With these additions, we can remove ~350L of
switch (crypto_info->cipher_type) { ... }
from tls_set_device_offload, tls_sw_fallback_init,
do_tls_getsockopt_conf, do_tls_setsockopt_conf, tls_set_sw_offload
(mainly do_tls_getsockopt_conf and tls_set_sw_offload).
This series also adds the ARIA ciphers to the tls selftests, and some
more getsockopt/setsockopt tests to cover more of the code changed by
this series.

tls_cipher_size_desc indexes ciphers by their type, but we're not
using indices 0..50 of the array. Each struct tls_cipher_size_desc is
20B, so that's a lot of unused memory. We can reindex the array
starting at the lowest used cipher_type.
Introduce the get_cipher_size_desc helper to find the right item and
avoid out-of-bounds accesses, and make tls_cipher_size_desc's size
explicit so that gcc reminds us to update TLS_CIPHER_MIN/MAX when we
add a new cipher.

tools/net/ynl: Add support for netlink-raw families
This patchset adds support for netlink-raw families such as rtnetlink.
Patch 1 fixes a typo in existing schemas
Patch 2 contains the schema definition
Patches 3 & 4 update the schema documentation
Patches 5 - 9 extends ynl
Patches 10 - 12 add several netlink-raw specs
The netlink-raw schema is very similar to genetlink-legacy and I thought
about making the changes there and symlinking to it. On balance I
thought that might be problematic for accurate schema validation.
rtnetlink doesn't seem to fit into unified or directional message
enumeration models. It seems like an 'explicit' model would be useful,
to force the schema author to specify the message ids directly.
There is not yet support for notifications because ynl currently doesn't
support defining 'event' properties on a 'do' operation. The message ids
are shared so ops need to be both sync and async. I plan to look at this
in a future patch.
The link and route messages contain different nested attributes
dependent on the type of link or route. Decoding these will need some
kind of attr-space selection that uses the value of another attribute as
the selector key. These nested attributes have been left with type
'binary' for now.
