Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.

configuration

control objects, save memory on systems with 64kB page size

hmac(sha256), hmac(sha384) and cts(cbc(aes)) algorithms have been
marked as FIPS allowed for years. Mark the respective authenc()
constructions per RFC 8009 ("AES Encryption with HMAC-SHA2 for
Kerberos 5") as such as well.
SP 800-57 Part 3 Rev. 1 from Jan 2015 [1] links the draft of what
became RFC 8009 in Oct 2016 as approved in section 6.3 Procurement

Remove the insecure FCrypt block cipher from the crypto API. Its only
user was net/rxrpc/, but now net/rxrpc/ implements it locally. The
crypto API implementation is no longer needed.
For some additional context: FCrypt was designed in 1988 and is
essentially a weakened version of DES. It has the same 56-bit key size
as DES, which is easily brute forced. Moreover, it's cryptographically
weak and doesn't even provide the intended 56-bit security level. Its
author considers it to be a mistake, as well
(https://lists.openafs.org/pipermail/openafs-devel/2000-December/005320.html).
But fortunately this 1980s-era homebrew block cipher was never adopted
outside of net/rxrpc/. So its code can just be kept there.

"Prediction resistance", i.e. the property that the RNG's output is
unpredictable even after a state compromise, might sound like a nice
property to have. In reality, it's not very practical, as it requires
that fresh entropy be pulled on every request. (The normal Linux RNG
doesn't provide prediction resistance.) In the case of drbg.c, that
means pulling from "jitterentropy", which is extremely slow.
For some perspective, running a simple benchmark, generating 32 random
bytes takes the following amount of time:
get_random_bytes(): 90 ns
drbg_nopr_hmac_sha512: 3707 ns
drbg_pr_hmac_sha512: 773082 ns
So at least in this case, the "pr" (prediction-resistant) DRBG is over
200 times slower than the "nopr" (non-prediction-resistant) DRBG, or
over 8000 times slower than the normal Linux RNG. While anyone using
drbg.c has always had to tolerate that it's slower than the normal Linux
RNG, the "pr" DRBG is clearly at another level of slowness.
Thus, the following is also entirely unsurprising:
- FIPS 140-3 doesn't actually require that SP800-90A DRBG
implementations support prediction resistance. The non-prediction
resistant DRBGs can be, and have been, certified.
- drbg.c registers "drbg_nopr_hmac_sha512" with a higher cra_priority
than "drbg_pr_hmac_sha512". So "drbg_nopr_hmac_sha512" is already
the one actually being used in practice.
Given these considerations, it's clear that "drbg_pr_hmac_sha512" isn't
actually useful, and it essentially just existed as another curiosity in
the museum of crypto algorithms. Remove it to simplify the code.

When booted with fips=1, RSA signature generation using SHA-1 must not be
available. However, pkcs1pad(rsa,sha1) can currently be instantiated
because it is not present in alg_test_descs; alg_test() falls through the
no_test path and succeeds, after which the algorithm appears in
/proc/crypto as fips-capable.
Add explicit alg_test_descs entries for pkcs1pad(rsa,sha1) and
pkcs1(rsa,sha1) without marking them fips_allowed, so they are treated as
not FIPS-allowed when fips=1 is enabled.
Include both names to cover kernels where RSA sign/verify is provided via
the pkcs1(...) signature template, while pkcs1pad(...) remains for the
traditional wrapper naming and/or RSAES operations.

Remove support for the HMAC-SHA256 and HMAC-SHA384 variants of
HMAC_DRBG, leaving only the HMAC-SHA512 variant of HMAC_DRBG.
HMAC-SHA512 is already the default. The default did used to be
HMAC-SHA256, but several years ago it was upgraded to HMAC-SHA512 "to
support compliance with SP800-90B and SP800-90C". Given that the point
of crypto/drbg.c is compliance with those standards, and there's also no
technical reason to prefer HMAC-SHA384 in this situation even if
acceptable, there's really no point in offering anything else.
Note: now that only HMAC-SHA512 remains, a lot of unnecessary
abstractions can be removed. A later commit will do that. This commit
just straightforwardly removes the HMAC-SHA256 and HMAC-SHA384 code.

Synchronize the drbg_nopr_hmac_sha512 test vector with the first test
vector from the latest ACVP json files, so that both of the DRBG test
vectors are pulled from a consistent source.
Note that the new test vector has a nonempty personalization string.
That should be helpful as well: Some FIPS labs require this, due to
their interpretation of SP800-90A 11.3.2 which says that a
"representative" value of the personalization string must be tested.
It also now does an explicit reseed, which makes it clearer that the
requirement to test "Reseed" is met, without having to interpret the
additional input processing as covering that.

Remove the support for HASH_DRBG. It's likely unused code, seeing as
HMAC_DRBG is always enabled and prioritized over it unless
NETLINK_CRYPTO is used to change the algorithm priorities.
There's also no compelling reason to support more than one of
[HMAC_DRBG, HASH_DRBG, CTR_DRBG]. By definition, callers cannot tell
any difference in their outputs. And all are FIPS-certifiable, which is
the only point of the kernel's NIST DRBGs anyway.
Switching to HASH_DRBG doesn't seem all that compelling, either. For
one, it's more complex than HMAC_DRBG.
Thus, let's just drop HASH_DRBG support and focus on HMAC_DRBG.

Remove the support for CTR_DRBG. It's likely unused code, seeing as
HMAC_DRBG is always enabled and prioritized over it unless
NETLINK_CRYPTO is used to change the algorithm priorities.
There's also no compelling reason to support more than one of
[HMAC_DRBG, HASH_DRBG, CTR_DRBG]. By definition, callers cannot tell
any difference in their outputs. And all are FIPS-certifiable, which is
the only point of the kernel's NIST DRBGs anyway.
Switching to CTR_DRBG doesn't seem all that compelling, either. While
it's often the fastest NIST DRBG, it has several disadvantages:
- CTR_DRBG uses AES. Some platforms don't have AES acceleration at all,
causing a fallback to the table-based AES code which is very slow and
can be vulnerable to cache-timing attacks. In contrast, HMAC_DRBG
uses primitives that are consistently constant-time.
- CTR_DRBG is usually considered to be somewhat less cryptographically
robust than HMAC_DRBG. Granted, HMAC_DRBG isn't all that great
either, e.g. given the negative result from Woodage & Shumow (2018)
(https://eprint.iacr.org/2018/349.pdf), but that can be worked around.
- CTR_DRBG is more complex than HMAC_DRBG, risking bugs. Indeed, while
reviewing the CTR_DRBG code, I found two bugs, including one where it
can return success while leaving the output buffer uninitialized.
- The kernel's implementation of CTR_DRBG uses an "ctr(aes)"
crypto_skcipher and relies on it returning the next counter value.
That's fragile, and indeed historically many "ctr(aes)"
crypto_skcipher implementations haven't done that. E.g. see
commit 511306b2d075 ("crypto: arm/aes-ce - update IV after partial final CTR block"),
commit fa5fd3afc7e6 ("crypto: arm64/aes-blk - update IV after partial final CTR block"),
commit 371731ec2179 ("crypto: atmel-aes - Fix saving of IV for CTR mode"),
commit 25baaf8e2c93 ("crypto: crypto4xx - fix ctr-aes missing output IV"),
commit 334d37c9e263 ("crypto: caam - update IV using HW support"),
commit 0a4491d3febe ("crypto: chelsio - count incomplete block in IV"),
commit e8e3c1ca57d4 ("crypto: s5p - update iv after AES-CBC op end").
I.e., there were many years where the kernel's CTR_DRBG code (if it
were to have actually been used) repeated outputs on some platforms.
AES-CTR also uses a 128-bit counter, which creates overflow edge cases
that are sometimes gotten wrong. E.g. see commit 009b30ac7444
("crypto: vmx - CTR: always increment IV as quadword").
So, while switching to CTR_DRBG for performance reasons isn't completely
out of the question (notably BoringSSL uses it), it would take quite a
bit more work to create a solid implementation of it in the kernel,
including a more solid implementation of AES-CTR itself (in lib/crypto/,
with a scalar bit-sliced fallback, etc). Since HMAC_DRBG has always
been the default NIST DRBG variant in the kernel and is in a better
state, let's just standardize on it for now.

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used. Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.
It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.

Reimplement the "sm3" crypto_shash on top of the SM3 library, closely
mirroring the other hash algorithms (e.g. SHA-*).
The result, after later commits migrate the architecture-optimized SM3
code into the library as well, is that crypto/sm3.c will be the single
point of integration between crypto_shash and the actual SM3
implementations, simplifying the code.
Note: to see the diff from crypto/sm3_generic.c to crypto/sm3.c, view

Make the "gcm" template access GHASH using the library API instead of
crypto_ahash. This is much simpler and more efficient, especially given
that all GHASH implementations are synchronous and CPU-based anyway.
Note that this allows "ghash" to be removed from the crypto_ahash (and
crypto_shash) API, which a later commit will do.
This mirrors the similar cleanup that was done with POLYVAL.

Update the "aes" module to implement "cmac(aes)", "xcbc(aes)", and
"cbcmac(aes)" algorithms using the corresponding library functions, and
register these with the crypto_shash API. Each algorithm is included
only if the corresponding existing kconfig option is enabled.
This allows the architecture-optimized implementations of these
algorithms to continue to be accessible via the crypto_shash API once
they are migrated into the library.
For "xcbc(aes)", I also fixed the bug where AES key lengths other than
128 bits were allowed, so that this bug didn't have to be implemented in
the library. The AES-XCBC-MAC specification (RFC 3566) is clear that
key lengths other than 128 bits MUST NOT be supported. AES-XCBC-MAC
derives a 128-bit subkey internally, so the nonstandard support for
longer AES keys didn't really work: AES-128 was still used internally.
In the unlikely event that someone is actually relying on the broken and
nonstandard support for longer AES-XCBC-MAC keys, we can fairly easily
reintroduce it. But it seems unnecessary: the only user of "xcbc(aes)"
seems to be IPsec, which uses 128-bit keys with it.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

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 *".

Now that the AES library's performance has been improved, replace
aes_generic.c with a new file aes.c which wraps the AES library.
In preparation for making the AES library actually utilize the kernel's
existing architecture-optimized AES code including AES instructions, set
the driver name to "aes-lib" instead of "aes-generic". This mirrors
what's been done for the hash algorithms. Update testmgr.c accordingly.
Since this removes the crypto_aes_set_key() helper function, add
temporary replacements for it to arch/arm/crypto/aes-cipher-glue.c and
arch/arm64/crypto/aes-cipher-glue.c. This is temporary, as that code
will be migrated into lib/crypto/ in later commits.

Reimplement the Adiantum message hashing using the nh() library
function, combined with some code which directly handles the Poly1305
stage. The latter code is derived from crypto/nhpoly1305.c.
This eliminates the dependency on the "nhpoly1305" crypto_shash
algorithm, which existed only to fit Adiantum message hashing into the
traditional Linux crypto API paradigm. Now that simple,
architecture-optimized library functions are a well-established option
too, we can switch to this simpler implementation.
Note: I've dropped the support for the optional third parameter of the
adiantum template, which specified the nhpoly1305 implementation. We
could keep accepting some strings in this parameter for backwards
compatibility, but I don't think it's being used. I believe only
"adiantum(xchacha12,aes)" and "adiantum(xchacha20,aes)" are used.

Remove ansi_cprng, since it's obsolete and unused, as confirmed at
https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/
This was originally added in 2008, apparently as a FIPS approved random
number generator. Whether this has ever belonged upstream is
questionable. Either way, ansi_cprng is no longer usable for this
purpose, since it's been superseded by the more modern algorithms in
crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A
Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after
2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.)
Therefore, there is no reason to keep it around.

The "hash function" in hctr2 is fixed at POLYVAL; it can never vary.
Just use the POLYVAL library, which is much easier to use than the
crypto_shash API. It's faster, uses fixed-size structs, and never fails
(all the functions return void).
Note that this eliminates the only known user of the polyval support in
crypto_shash. A later commit will remove support for polyval from
crypto_shash, given that the library API is sufficient.

For the "chacha20", "xchacha20", and "xchacha12" skcipher algorithms,
instead of registering "*-generic" drivers as well as conditionally
registering "*-$(ARCH)" drivers, instead just register "*-lib" drivers.
These just use the regular library functions, so they just do the right
thing and are fully accelerated when supported by the CPU.
This eliminates the need for the ChaCha library to support
chacha_crypt_generic() and hchacha_block_generic() as part of its
external interface. A later commit will make chacha_crypt_generic() a
static function.
Since this commit removes several "*-generic" driver names which
crypto/testmgr.c expects to exist, update testmgr.c accordingly.

Reimplement crypto/md5.c on top of the new MD5 library functions. Also
add support for HMAC-MD5, again just wrapping the library functions.
This closely mirrors crypto/sha1.c.
