* crypto: ecc - Fix off-by-one missing to clear most significant digitStefan Berger2024-06-161-1/+1
| | | | | | | | | | | | | | | | Fix an off-by-one error where the most significant digit was not initialized leading to signature verification failures by the testmgr. Example: If a curve requires ndigits (=9) and diff (=2) indicates that 2 digits need to be set to zero then start with digit 'ndigits - diff' (=7) and clear 'diff' digits starting from there, so 7 and 8.

* crypto: sm2 - Remove sm2 algorithmHerbert Xu2024-06-0710-635/+2
| | | | | | | | | | | | | | The SM2 algorithm has a single user in the kernel. However, it's never been integrated properly with that user: asymmetric_keys. The crux of the issue is that the way it computes its digest with sm3 does not fit into the architecture of asymmetric_keys. As no solution has been proposed, remove this algorithm. It can be resubmitted when it is integrated properly into the asymmetric_keys subsystem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ecdsa - Use ecc_digits_from_bytes to convert signatureStefan Berger2024-06-071-10/+2
| | | | | | | | | | | | Since ecc_digits_from_bytes will provide zeros when an insufficient number of bytes are passed in the input byte array, use it to convert the r and s components of the signature to digits directly from the input byte array. This avoids going through an intermediate byte array that has the first few bytes filled with zeros.

| | | | | | | | | | | | | | Since crypto_shash_setkey(), crypto_ahash_setkey(), crypto_skcipher_setkey(), and crypto_aead_setkey() apparently need to work in no-SIMD context on some architectures, make the self-tests cover this scenario. Specifically, sometimes do the setkey while under crypto_disable_simd_for_test(), and do this independently from disabling SIMD for the other parts of the crypto operation since there is no guarantee that all parts happen in the same context. (I.e., drivers mustn't store the key in different formats for SIMD vs. no-SIMD.) Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent ecc_digits_from_bytes from reading too many bytes from the input byte array in case an insufficient number of bytes is provided to fill the output digit array of ndigits. Therefore, initialize the most significant digits with 0 to avoid trying to read too many bytes later on. Convert the function into a regular function since it is getting too big for an inline function. If too many bytes are provided on the input byte array the extra bytes are ignored since the input variable 'ndigits' limits the number of digits that will be filled.

The PKCS#7 signature verification API builds upon the KCAPI primitives to perform its high-level operations. Therefore, this change in testmgr.c also allows ECDSA to be used by the PKCS#7 signature verification API (in FIPS mode). However, from a FIPS perspective, the PKCS#7 signature verification API is a distinct "service" from the KCAPI primitives. This is because the PKCS#7 API performs a "full" signature verification, which consists of both hashing the data to be verified, and the public key operation. On the other hand, the KCAPI primitive does not perform this hashing step - it accepts pre-hashed data from the caller and only performs the public key operation. For this reason, the ECDSA self-tests in crypto/testmgr.c are not sufficient to cover ECDSA signature verification offered by the PKCS#7 API. This is reflected by the self-test already present in this file for RSA PKCS#1 v1.5 signature verification. The solution is simply to add a second self-test here for ECDSA. P-256 with SHA-256 hashing was chosen as those parameters should remain FIPS-approved for the foreseeable future, while keeping the performance impact to a minimum. The ECDSA certificate and PKCS#7 signed data was generated using OpenSSL. The input data is identical to the input data for the existing RSA self-test.

This file is only compiled if the new CONFIG_FIPS_SIGNATURE_SELFTEST_RSA configuration option is set, which ensures that the required dependencies (RSA, SHA-256) are present. Otherwise, the kernel would panic when trying to execute the self-test. The introduction of this new option, rather than adding the dependencies to the existing CONFIG_FIPS_SIGNATURE_SELFTEST option, allows for additional self-tests to be added for different algorithms. The kernel can then be configured to only execute the self-tests for those algorithms that are included.

AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The private key in ctx->private_key is currently initialized in reverse byte order in ecdh_set_secret and whenever the key is needed in proper byte order the variable priv is introduced and the bytes from ctx->private_key are copied into priv while being byte-swapped (ecc_swap_digits). To get rid of the unnecessary byte swapping initialize ctx->private_key in proper byte order and clean up all functions that were previously using priv or were called with ctx->private_key: - ecc_gen_privkey: Directly initialize the passed ctx->private_key with random bytes filling all the digits of the private key. Get rid of the priv variable. This function only has ecdh_set_secret as a caller to create NIST P192/256/384 private keys. - crypto_ecdh_shared_secret: Called only from ecdh_compute_value with ctx->private_key. Get rid of the priv variable and work with the passed private_key directly. - ecc_make_pub_key: Called only from ecdh_compute_value with ctx->private_key.

| * crypto: ecdh - Pass private key in proper byte order to check valid keyStefan Berger2024-04-261-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ecc_is_key_valid expects a key with the most significant digit in the last entry of the digit array. Currently ecdh_set_secret passes a reversed key to ecc_is_key_valid that then passes the rather simple test checking whether the private key is in range [2, n-3]. For all current ecdh- supported curves (NIST P192/256/384) the 'n' parameter is a rather large number, therefore easily passing this test. Throughout the ecdh and ecc codebase the variable 'priv' is used for a private_key holding the bytes in proper byte order. Therefore, introduce priv in ecdh_set_secret and copy the bytes from ctx->private_key into priv in proper byte order by using ecc_swap_digits. Pass priv to ecc_is_valid_key.

| * X.509: Introduce scope-based x509_certificate allocationLukas Wunner2024-04-123-49/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a DEFINE_FREE() clause for x509_certificate structs and use it in x509_cert_parse() and x509_key_preparse(). These are the only functions where scope-based x509_certificate allocation currently makes sense. A third user will be introduced with the forthcoming SPDM library (Security Protocol and Data Model) for PCI device authentication. Unlike most other DEFINE_FREE() clauses, this one checks for IS_ERR() instead of NULL before calling x509_free_certificate() at end of scope. That's because the "constructor" of x509_certificate structs, x509_cert_parse(), returns a valid pointer or an ERR_PTR(), but never NULL. Comparing the Assembler output before/after has shown they are identical, save for the fact that gcc-12 always generates two return paths when __cleanup() is used, one for the success case and one for the error case. In x509_cert_parse(), add a hint for the compiler that kzalloc() never returns an ERR_PTR(). Otherwise the compiler adds a gratuitous IS_ERR() check on return. Introduce an assume() macro for this which can be re-used elsewhere in the kernel to provide hints for the compiler.

While existing curves may prepend a 0 byte to their coordinates (to make the number positive), NIST P521 will not do this since only the first bit in the most significant byte is used. If the encoding of the x & y coordinates requires at least 128 bytes then an additional byte is needed for the encoding of the length.

Further, it is true that for the NIST curves p > n with 'n' being the 'curve_order' and therefore the following may be true as well: p > res.x >= n. If res.x >= n then res.x mod n can be calculated by iteratively sub- tracting n from res.x until res.x < n. For NIST P192/256/384 this can be done in a single subtraction. This can also be done in a single subtraction for NIST P521. The mathematical reason why a single subtraction is sufficient is due to the values of 'p' and 'n' of the NIST curves where the following holds true: note: max(res.x) = p - 1 max(res.x) - n < n p - 1 - n < n p - 1 < 2n => holds true for the NIST curves Tested-by: Lukas Wunner <lukas@wunner.de> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Stefan Berger <stefanb@linux.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: ecdsa - Adjust tests on length of key parametersStefan Berger2024-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for support of NIST P521, adjust the basic tests on the length of the provided key parameters to only ensure that the length of the x plus y coordinates parameter array is not an odd number and that each coordinate fits into an array of 'ndigits' digits. Mathematical tests on the key's parameters are then done in ecc_is_pubkey_valid_full rejecting invalid keys. The change is necessary since NIST P521 keys do not have keys with coordinates that each require 'full' digits (= all bits in u64 used). NIST P521 only requires 2 bytes (9 bits) in the most significant digit unlike NIST P192/256/384 that each require multiple 'full' digits.

| * crypto: ecdsa - Convert byte arrays with key coordinates to digitsStefan Berger2024-04-121-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For NIST P192/256/384 the public key's x and y parameters could be copied directly from a given array since both parameters filled 'ndigits' of digits (a 'digit' is a u64). For support of NIST P521 the key parameters need to have leading zeros prepended to the most significant digit since only 2 bytes of the most significant digit are provided. Therefore, implement ecc_digits_from_bytes to convert a byte array into an array of digits and use this function in ecdsa_set_pub_key where an input byte array needs to be converted into digits.

| * crypto: ecdh - explicitly zeroize private_keyJoachim Vandersmissen2024-04-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | private_key is overwritten with the key parameter passed in by the caller (if present), or alternatively a newly generated private key. However, it is possible that the caller provides a key (or the newly generated key) which is shorter than the previous key. In that scenario, some key material from the previous key would not be overwritten. The easiest solution is to explicitly zeroize the entire private_key array first. Note that this patch slightly changes the behavior of this function: previously, if the ecc_gen_privkey failed, the old private_key would remain. Now, the private_key is always zeroized. This behavior is consistent with the case where params.key is set and ecc_is_key_valid fails.

| * crypto: ecc - update ecc_gen_privkey for FIPS 186-5Joachim Vandersmissen2024-04-021-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FIPS 186-5 [1] was released approximately 1 year ago. The most interesting change for ecc_gen_privkey is the removal of curves with order < 224 bits. This is minimum is now checked in step 1. It is unlikely that there is still any benefit in generating private keys for curves with n < 224, as those curves provide less than 112 bits of security strength and are therefore unsafe for any modern usage. This patch also updates the documentation for __ecc_is_key_valid and ecc_gen_privkey to clarify which FIPS 186-5 method is being used to generate private keys. Previous documentation mentioned that "extra random bits" was used. However, this did not match the code. Instead, the code currently uses (and always has used) the "rejection sampling" ("testing candidates" in FIPS 186-4) method.
