2020-09-18crypto: inside-secure - Prevent missing of processing errorsPascal van Leeuwen1-4/+5
On systems with coherence issues, packet processed could succeed while it should have failed, e.g. because of an authentication fail. This is because the driver would read stale status information that had all error bits initialised to zero = no error. Since this is potential a security risk, we want to prevent it from being a possibility at all. So initialize all error bits to error state, so that reading stale status information will always result in errors.

2020-09-11hwrng: imx-rngc - add quality to use it as kernel entropy poolMarco Felsch1-0/+1
The RNGB can generate 2^20 words (1 word == 4 byte) of 'random' data after the seed pool was initialized. The pool needs to be reseeded if more words are required. The reseeding is done automatically since commit 3acd9ea9331c ("hwrng: imx-rngc - use automatic seeding"). We can't retrieve the TRNG values directly so we need a other way to get the quality level. We know that the PRNG uses 20.000 entropy samples from the TRNG to generate 2^20 words (1MiB) and the quality level is defined as (in bits of entropy per 1024 bits of input). So the quality level can be calculated by: 20.000 * 1024 ------------- = ~ 19.5 2^20 Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch fixes most of the sparse endianness warnings in stm32. The patch itself doesn't change anything apart from markings, but there is some questionable code in stm32_cryp_check_ctr_counter. That function operates on the counters as if they're in CPU order, however, they're then written out as big-endian. This looks like a genuine bug.

2020-08-28crypto: mediatek - Fix endianness bugs and sparse warningsHerbert Xu2-34/+25
This patch squashes all the sparse warnings in mediatek, some of which appear to be genuine bugs. In particular, previously on BE the keys and IVs all get 32-bit swabbed which can't be right because they don't get swabbed on LE. I presume LE is the one that actually works. Another funky thing is that the GHASH key gets swabbed on LE. This makes no sense but I'm presuming someone actually tested this on LE so I'm preserving the swabbing. Someone needs to test this though as it is entirely possible that GCM is the only thing that worked on BE but not LE. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

When the devices are removed or not existing, the corresponding algorithms which are registered by 'hisi-zip' driver can't be used. Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to 'hisi_zip_probe'. The algorithms will be registered to crypto only when there is device bind on the driver. And when the devices are removed, the algorithms will be unregistered. In the previous process, the function 'xxx_register_to_crypto' need a lock and a static variable to judge if the registration is the first time. Move this action into the function 'hisi_qm_alg_register'. Each device will call 'hisi_qm_alg_register' to add itself to qm list in probe process and registering algs when the qm list is empty.
