2021-06-10async_xor: check src_offs is not NULL before updating itXiao Ni
When PAGE_SIZE is greater than 4kB, multiple stripes may share the same page. Thus, src_offs is added to async_xor_offs() with array of offsets. However, async_xor() passes NULL src_offs to async_xor_offs(). In such case, src_offs should not be updated. Add a check before the update.

2021-04-26async_xor: increase src_offs when dropping destination pageXiao Ni
Now we support sharing one page if PAGE_SIZE is not equal stripe size. To support this, it needs to support calculating xor value with different offsets for each r5dev. One offset array is used to record those offsets. In RMW mode, parity page is used as a source page. It sets ASYNC_TX_XOR_DROP_DST before calculating xor value in ops_run_prexor5. So it needs to add src_list and src_offs at the same time. Now it only needs src_list. So the xor value which is calculated is wrong. It can cause data corruption problem. I can reproduce this problem 100% on a POWER8 machine. The steps are: mdadm -CR /dev/md0 -l5 -n3 /dev/sdb1 /dev/sdc1 /dev/sdd1 --size=3G mkfs.xfs /dev/md0 mount /dev/md0 /mnt/test mount: /mnt/test: mount(2) system call failed: Structure needs cleaning.

This may want reconsideration in the future, but, currently, you can't add to the blacklist keyring from userspace and the only source of blacklist keys generates lowercase descriptions. - Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.

2021-02-10crypto: ecdh_helper - Ensure 'len >= secret.len' in decode_key()Daniele Alessandrelli
The length ('len' parameter) passed to crypto_ecdh_decode_key() is never checked against the length encoded in the passed buffer ('buf' parameter). This could lead to an out-of-bounds access when the passed length is less than the encoded length. Add a check to prevent that.

Instead of using an alignmask of 0x3 to ensure 32-bit alignment of the Twofish input and output blocks, which propagates to mode drivers, and results in pointless copying on architectures that don't care about alignment, use the unaligned accessors, which will do the right thing on each respective architecture, avoiding the need for double buffering.

2021-02-10crypto: serpent - get rid of obsolete tnepres variantArd Biesheuvel
It is not trivial to trace back why exactly the tnepres variant of serpent was added ~17 years ago - Google searches come up mostly empty, but it seems to be related with the 'kerneli' version, which was based on an incorrect interpretation of the serpent spec. In other words, nobody is likely to care anymore today, so let's get rid of it. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-02-10crypto: michael_mic - fix broken misalignment handlingArd Biesheuvel
The Michael MIC driver uses the cra_alignmask to ensure that pointers presented to its update and finup/final methods are 32-bit aligned. However, due to the way the shash API works, this is no guarantee that the 32-bit reads occurring in the update method are also aligned, as the size of the buffer presented to update may be of uneven length. For instance, an update() of 3 bytes followed by a misaligned update() of 4 or more bytes will result in a misaligned access using an accessor that is not suitable for this. On most architectures, this does not matter, and so setting the cra_alignmask is pointless. On architectures where this does matter, setting the cra_alignmask does not actually solve the problem. So let's get rid of the cra_alignmask, and use unaligned accessors instead, where appropriate.
