Pull EFI updates from Ard Biesheuvel: "Not a lot going on in the EFI tree this cycle. The only thing that stands out is the new support for SBAT metadata, which was a bit contentious when it was first proposed, because in the initial incarnation, it would have required us to maintain a revocation index, and bump it each time a vulnerability affecting UEFI secure boot got fixed. This was shot down for obvious reasons. This time, only the changes needed to emit the SBAT section into the PE/COFF image are being carried upstream, and it is up to the distros to decide what to put in there when creating and signing the build. This only has the EFI zboot bits (which the distros will be using for arm64); the x86 bzImage changes should be arriving next cycle, presumably via the -tip tree. Summary: - Add support for emitting a .sbat section into the EFI zboot image, so that downstreams can easily include revocation metadata in the signed EFI images - Align PE symbolic constant names with other projects - Bug fix for the efi_test module - Log the physical address and size of the EFI memory map when failing to map it - A kerneldoc fix for the EFI stub code" * tag 'efi-next-for-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: include: pe.h: Fix PE definitions efi/efi_test: Fix missing pending status update in getwakeuptime efi: zboot specific mechanism for embedding SBAT section efi/libstub: Describe missing 'out' parameter in efi_load_initrd efi: Improve logging around memmap init

Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers: - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver.

2025-05-23crypto: api - Redo lookup on EEXISTHerbert Xu1-2/+11
When two crypto algorithm lookups occur at the same time with different names for the same algorithm, e.g., ctr(aes-generic) and ctr(aes), they will both be instantiated. However, only one of them can be registered. The second instantiation will fail with EEXIST. Avoid failing the second lookup by making it retry, but only once because there are tricky names such as gcm_base(ctr(aes),ghash) that will always fail, despite triggering instantiation and EEXIST.

2025-05-19crypto: testmgr - Ignore EEXIST on shash allocationHerbert Xu1-1/+1
Soon hmac will support ahash. For compatibility hmac still supports shash so it is possible for two hmac algorithms to be registered at the same time. The shash algorithm will have the driver name "hmac-shash(XXX-driver)". Due to a quirk in the API, there is no way to locate the shash algorithm using the name "hmac(XXX-driver)". It has to be addressed as either "hmac(XXX)" or "hmac-shash(XXX-driver)". Looking it up with "hmac(XXX-driver)" will simply trigger the creation of another instance, and on the second instantiation this will fail with EEXIST. Catch the error EEXIST along with ENOENT since it is expected. If a real shash algorithm came this way, it would be addressed using the proper name "hmac-shash(XXX-driver)".

2025-05-19crypto: ahash - Handle partial blocks in APIHerbert Xu1-279/+248
Provide an option to handle the partial blocks in the ahash API. Almost every hash algorithm has a block size and are only able to hash partial blocks on finalisation. As a first step disable virtual address support for algorithms with state sizes larger than HASH_MAX_STATESIZE. This is OK as virtual addresses are currently only used on synchronous fallbacks. This means ahash_do_req_chain only needs to handle synchronous fallbacks, removing the complexities of saving the request state. Also move the saved request state into the ahash_request object as nesting is no longer possible. Add a scatterlist to ahash_request to store the partial block.

2025-05-12crypto: testmgr - make it easier to enable the full set of testsEric Biggers2-67/+5
Currently the full set of crypto self-tests requires CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y. This is problematic in two ways. First, developers regularly overlook this option. Second, the description of the tests as "extra" sometimes gives the impression that it is not required that all algorithms pass these tests. Given that the main use case for the crypto self-tests is for developers, make enabling CONFIG_CRYPTO_SELFTESTS=y just enable the full set of crypto self-tests by default. The slow tests can still be disabled by adding the command-line parameter cryptomgr.noextratests=1, soon to be renamed to cryptomgr.noslowtests=1. The only known use case for doing this is for people trying to use the crypto self-tests to satisfy the FIPS 140-3 pre-operational self-testing requirements when the kernel is being validated as a FIPS 140-3 cryptographic module.

The negative-sense of CRYPTO_MANAGER_DISABLE_TESTS is a longstanding mistake that regularly causes confusion. Especially bad is that you can have CRYPTO=n && CRYPTO_MANAGER_DISABLE_TESTS=n, which is ambiguous. Replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS which has the expected behavior.

crypto_get_default_null_skcipher() and crypto_put_default_null_skcipher() are no longer used, so remove them. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-12crypto: krb5enc - do not select CRYPTO_NULLEric Biggers1-1/+0
The krb5enc code does not use any of the so-called "null algorithms", so it does not need to select CRYPTO_NULL. Presumably this unused dependency got copied from one of the other kconfig options.

2025-05-12crypto: geniv - use memcpy_sglist() instead of null skcipherEric Biggers4-42/+7
For copying data between two scatterlists, just use memcpy_sglist() instead of the so-called "null skcipher". This is much simpler. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2025-05-12crypto: lib/chacha - add array bounds to function prototypesEric Biggers1-2/+2
Add explicit array bounds to the function prototypes for the parameters that didn't already get handled by the conversion to use chacha_state: - chacha_block_*(): Change 'u8 *out' or 'u8 *stream' to u8 out[CHACHA_BLOCK_SIZE]. - hchacha_block_*(): Change 'u32 *out' or 'u32 *stream' to u32 out[HCHACHA_OUT_WORDS]. - chacha_init(): Change 'const u32 *key' to 'const u32 key[CHACHA_KEY_WORDS]'. Change 'const u8 *iv' to 'const u8 iv[CHACHA_IV_SIZE]'. No functional changes. This just makes it clear when fixed-size arrays are expected.

2025-05-12crypto: lib/chacha - strongly type the ChaCha stateEric Biggers1-8/+8
The ChaCha state matrix is 16 32-bit words. Currently it is represented in the code as a raw u32 array, or even just a pointer to u32. This weak typing is error-prone. Instead, introduce struct chacha_state: struct chacha_state { u32 x[16]; }; Convert all ChaCha and HChaCha functions to use struct chacha_state. No functional changes.

2025-05-05crypto: ahash - Add core export and importHerbert Xu1-1/+24
Add crypto_ahash_export_core and crypto_ahash_import_core. For now they only differ from the normal export/import functions when going through shash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-05crypto: ahash - Enforce MAX_SYNC_HASH_REQSIZE for sync ahashHerbert Xu1-9/+18
As sync ahash algorithms (currently there are none) are used without a fallback, ensure that they obey the MAX_SYNC_HASH_REQSIZE rule just like shash algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Mark shash algorithms with the REQ_VIRT bit as they can handle virtual addresses as is. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-05crypto: shash - Cap state size to HASH_MAX_STATESIZEHerbert Xu1-0/+2
Now that all shash algorithms have converted over to the generic export format, limit the shash state size to HASH_MAX_STATESIZE. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-05crypto: sha256 - Use the partial block APIHerbert Xu1-23/+58
Use the shash partial block API by default. Add a separate set of lib shash algorithms to preserve testing coverage until lib/sha256 has its own tests. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-05crypto: sha256 - Use the partial block API for genericHerbert Xu1-37/+42
The shash interface already handles partial blocks, use it for sha224-generic and sha256-generic instead of going through the lib/sha256 interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-05-05crypto: api - Rename CRYPTO_ALG_REQ_CHAIN to CRYPTO_ALG_REQ_VIRTHerbert Xu4-7/+7
As chaining has been removed, all that remains of REQ_CHAIN is just virtual address support. Rename it before the reintroduction of batching creates confusion. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2025-05-05Revert "crypto: run initcalls for generic implementations earlier"Herbert Xu76-82/+76
This reverts commit c4741b23059794bd99beef0f700103b0d983b3fd. Crypto API self-tests no longer run at registration time and now occur either at late_initcall or upon the first use. Therefore the premise of the above commit no longer exists. Revert it and subsequent additions of subsys_initcall and arch_initcall. Note that lib/crypto calls will stay at subsys_initcall (or rather downgraded from arch_initcall) because they may need to occur before Crypto API registration.
