crypto: inside-secure/eip93 - unregister only available algorithm

2026-02-26T22:59:04+00:00

[ Upstream commit 0ceeadc7b53a041d89d5843f6bf0ccb7c98b0b4f ] EIP93 has an options register. This register indicates which crypto algorithms are implemented in silicon. Supported algorithms are registered on this basis. Unregister algorithms on the same basis. Currently, all algorithms are unregistered, even those not supported by HW. This results in panic on platforms that don't have all options implemented in silicon.

crypto: inside-secure/eip93 - fix kernel panic in driver detach

[ Upstream commit b6e32ba6d32503440a3e3e16c8d0521cbb7e0c5d ] During driver detach, the same hash algorithm is unregistered multiple times due to a wrong iterator.

crypto: eip93 - Make read-only arrays static const

2025-04-07T05:22:27+00:00

Don't populate the read-only arrays sha256_init, sha224_init, sha1_init and md5_init on the stack at run time, instead make them static. Signed-off-by: Colin Ian King Reviewed-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure/eip93 - acquire lock on eip93_put_descriptor hash

2025-04-03T11:04:33+00:00

In the EIP93 HASH functions, the eip93_put_descriptor is called without acquiring lock. This is problematic when multiple thread execute hash operations. Correctly acquire ring write lock on calling eip93_put_descriptor to prevent concurrent access and mess with the ring pointers.

crypto: inside-secure/eip93 - Correctly handle return of for sg_nents_for_len

2025-02-22T07:56:03+00:00

Fix smatch warning for sg_nents_for_len return value in Inside Secure EIP93 driver. The return value of sg_nents_for_len was assigned to an u32 and the error was ignored and converted to a positive integer. Rework the code to correctly handle the error from sg_nents_for_len to mute smatch warning.

crypto: eip93 - Add Inside Secure SafeXcel EIP-93 crypto engine support

2025-02-09T10:08:11+00:00

Add support for the Inside Secure SafeXcel EIP-93 Crypto Engine used on Mediatek MT7621 SoC and new Airoha SoC. EIP-93 IP supports AES/DES/3DES ciphers in ECB/CBC and CTR modes as well as authenc(HMAC(x), cipher(y)) using HMAC MD5, SHA1, SHA224 and SHA256. EIP-93 provide regs to signal support for specific chipers and the driver dynamically register only the supported one by the chip.
