crypto: ccree - use the full crypt length value

2019-10-11T16:36:05+00:00

commit 7a4be6c113c1f721818d1e3722a9015fe393295c upstream. In case of AEAD decryption verifcation error we were using the wrong value to zero out the plaintext buffer leaving the end of the buffer with the false plaintext.

crypto: ccree - don't map AEAD key and IV on stack

2019-04-25T07:38:16+00:00

The AEAD authenc key and IVs might be passed to us on stack. Copy it to a slab buffer before mapping to gurantee proper DMA mapping. Signed-off-by: Gilad Ben-Yossef Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu

crypto: ccree - don't mangle the request assoclen

2019-04-25T07:38:15+00:00

We were mangling the request struct assoclen field. Fix it by keeping an internal version and working on it. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - remove unused defines

2019-04-25T07:38:15+00:00

Remove unused definitions from AEAD driver code. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - do not copy zero size MLLI table

2019-04-25T07:38:15+00:00

When we are given a 0 sized cryptlen and assoclen in a scatterlist with two entries we were falsely trying to create a zero length MLLI table, causing the HW to choke. Don't try to copy a zero sized MLLI table. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - zero out internal struct before use

2019-04-25T07:38:15+00:00

We did not zero out the internal struct before use causing problem in some rare error code paths. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - copyright header update

2019-04-25T07:38:14+00:00

This sacrificial copyright header update is offered to the legal department as atonement for any changes made in this driver files in the course of the current year which have not been duly recorded as such. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - fix backlog notifications

2019-04-25T07:38:14+00:00

We were doing backlog notification callbacks via a cipher/hash/aead request structure cast to the base structure, which may or may not work based on how the structure is laid in memory and is not safe. Fix it by delegating the backlog notification to the appropriate internal callbacks which are type aware.

crypto: ccree - Forbid 2-key 3DES in FIPS mode

2019-04-18T14:14:59+00:00

This patch forbids the use of 2-key 3DES (K1 == K3) in FIPS mode. Signed-off-by: Herbert Xu Acked-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - convert to use crypto_authenc_extractkeys()

2019-01-10T13:37:31+00:00

Convert the ccree crypto driver to use crypto_authenc_extractkeys() so that it picks up the fix for broken validation of rtattr::rta_len. Fixes: ff27e85a85bb ("crypto: ccree - add AEAD support") Cc: # v4.17+ Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu
