Based on seqiv, IPsec ESP and rfc4543/rfc4106 the assoclen can be 16 or 20 bytes. From esp4/esp6, assoclen is sizeof IP Header. This includes spi, seq_no and extended seq_no, that is 8 or 12 bytes.

A QM integrated in an accelerator provides queue management service. Queues can be assigned to PF and VFs, and queues can be controlled by unified mailboxes and doorbells. Specific task request are descripted by specific description buffer, which will be controlled and pass to related accelerator IP by QM.

The crypto engine initializes its kworker thread to FIFO-99 (when requesting RT priority), reduce this to FIFO-50. FIFO-99 is the very highest priority available to SCHED_FIFO and it not a suitable default; it would indicate the crypto work is the most important work on the machine.

2019-08-09crypto: caam - execute module exit point only if necessaryIuliana Prodan2-1/+24
Commit 1b46c90c8e00 ("crypto: caam - convert top level drivers to libraries") changed entry and exit points behavior for caamalg, caamalg_qi, caamalg_qi2, caamhash, caampkc, caamrng. For example, previously caam_pkc_init() and caam_pkc_exit() were module entry/exit points. This means that if an error would happen in caam_pkc_init(), then caam_pkc_exit() wouldn't have been called. After the mentioned commit, caam_pkc_init() and caam_pkc_exit() are manually called - from jr.c. caam_pkc_exit() is called unconditionally, even if caam_pkc_init() failed. Added a global variable to keep the status of the algorithm registration and free of resources. The exit point of caampkc/caamrng module is executed only if the registration was successful. Therefore we avoid double free of resources in case the algorithm registration failed.

2019-08-09crypto: caam - fix MDHA key derivation for certain user key lengthsHoria Geantă6-105/+132
Fuzz testing uncovered an issue when |user key| > |derived key|. Derived key generation has to be fixed in two cases: 1. Era >= 6 (DKP is available) DKP cannot be used with immediate input key if |user key| > |derived key|, since the resulting descriptor (after DKP execution) would be invalid - having a few bytes from user key left in descriptor buffer as incorrect opcodes. Fix DKP usage both in standalone hmac and in authenc algorithms. For authenc the logic is simplified, by always storing both virtual and dma key addresses. 2. Era < 6 The same case (|user key| > |derived key|) fails when DKP is not available. Make sure gen_split_key() dma maps max(|user key|, |derived key|), since this is an in-place (bidirectional) operation.

2019-08-02crypto: api - Remove redundant #ifdef in crypto_yield()Thomas Gleixner1-2/+0
While looking at CONFIG_PREEMPT dependencies treewide the #ifdef in crypto_yield() matched. CONFIG_PREEMPT and CONFIG_PREEMPT_VOLUNTARY are mutually exclusive so the extra !CONFIG_PREEMPT conditional is redundant. cond_resched() has only an effect when CONFIG_PREEMPT_VOLUNTARY is set, otherwise it's a stub which the compiler optimizes out. Remove the whole conditional. No functional change. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: linux-crypto@vger.kernel.org Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: "David S.

2019-08-02crypto: jitterentropy - build without sanitizerArnd Bergmann1-0/+2
Recent clang-9 snapshots double the kernel stack usage when building this file with -O0 -fsanitize=kernel-hwaddress, compared to clang-8 and older snapshots, this changed between commits svn364966 and svn366056: crypto/jitterentropy.c:516:5: error: stack frame size of 2640 bytes in function 'jent_entropy_init' [-Werror,-Wframe-larger-than=] int jent_entropy_init(void) ^ crypto/jitterentropy.c:185:14: error: stack frame size of 2224 bytes in function 'jent_lfsr_time' [-Werror,-Wframe-larger-than=] static __u64 jent_lfsr_time(struct rand_data *ec, __u64 time, __u64 loop_cnt) ^ I prepared a reduced test case in case any clang developers want to take a closer look, but from looking at the earlier output it seems that even with clang-8, something was very wrong here. Turn off any KASAN and UBSAN sanitizing for this file, as that likely clashes with -O0 anyway. Turning off just KASAN avoids the warning already, but I suspect both of these have undesired side-effects for jitterentropy.
