crypto: keembay - use crypto_memneq() to compare CCM AEAD tags

2026-08-15T01:28:36+00:00

Use crypto_memneq() for constant-time comparison. The CCM path in ocs-aes.c verifes the received authentication tag with memcmp(), which returns early on the first mismatched byte. This leaks valid-prefix length and allows for valid tag forgery which violates the INT-CTXT guarantee of AEAD. Assisted-by: gregkh_clanker_t1000 Signed-off-by: David C.C.M.

crypto: keembay - Remove redundant dev_err()

2026-07-27T00:29:27+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_threaded_irq() automatically logs detailed error messages on failure. Remove the now-redundant driver-specific dev_err() calls. Signed-off-by: Pan Chuang Signed-off-by: Herbert Xu

crypto: keembay - publish OF module alias for OCS AES/SM4

2026-07-27T00:29:26+00:00

The Keem Bay OCS AES/SM4 driver has an OF match table wired to .of_match_table, but does not export the table with MODULE_DEVICE_TABLE(). Although the match table lives in keembay-ocs-aes-core.o, that object is part of the composite keembay-ocs-aes module. Add the missing MODULE_DEVICE_TABLE(of, ...) entry so modpost can generate OF module alias information for OF based module autoloading. This is a source-level fix. It does not claim dynamic hardware reproduction; the evidence is the driver-owned match table, its use by the platform driver, and the missing module alias publication.

crypto: keembay - Initialize completion before requesting IRQ

2026-07-27T00:29:26+00:00

kmb_ocs_aes_probe() requests the device IRQ before initializing irq_completion. Once the handler is registered it can run immediately, and ocs_aes_irq_handler() unconditionally calls complete(). An interrupt in this window would therefore use an uninitialized completion. Initialize the completion before requesting the IRQ, as the sibling OCS HCU and ECC drivers already do.

crypto: keembay - Fix AEAD unregister count in error path

2026-07-05T05:27:16+00:00

register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms. If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size. Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered. Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same call, while this function must still unwind earlier successful registration steps.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.
