While the CPU that sets 'WAIT_UNCLOCKED' is in IDLE state of "WAIT", if the other CPU wakes up and enters IDLE state of "WFI" istead of "WAIT", this CPU can not wake up at expired time. Because, in the case of "WFI", the CPU must be waked up by the local timer interrupt. But, while 'WAIT_UNCLOCKED' is set, the local timer is stopped, when all CPUs execute "wfi" instruction. As a result, the local timer interrupt is not fired. In this situation, this CPU will wake up by IRQ different from local timer. (e.g. broacast timer) So, this fix changes CPU to return to 'WAIT_CLOCKED'.

[PATCH] mm: Fix modifying of page protection by insert_pfn_pmd()

by Aneesh Kumar K.V

With some architectures like ppc64, set_pmd_at() cannot cope with a situation where there is already some (different) valid entry present. Use pmdp_set_access_flags() instead to modify the pfn which is built to deal with modifying existing PMD entries. This is similar to commit cae85cb8add3 ("mm/memory.c: fix modifying of page protection by insert_pfn()") We also do similar update w.r.t insert_pfn_pud eventhough ppc64 don't support pud pfn entries now.

[RFC/RFT PATCH 06/18] crypto: chacha20poly1305 - set cra_name correctly

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> If the rfc7539 template is instantiated with specific implementations, e.g. "rfc7539(chacha20-generic,poly1305-generic)" rather than "rfc7539(chacha20,poly1305)", then the implementation names end up included in the instance's cra_name. This is incorrect because it then prevents all users from allocating "rfc7539(chacha20,poly1305)", if the highest priority implementations of chacha20 and poly1305 were selected.

[RFC/RFT PATCH 01/18] crypto: x86/poly1305 - fix overflow during partial reduction

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> The x86_64 implementation of Poly1305 produces the wrong result on some inputs because poly1305_4block_avx2() incorrectly assumes that when partially reducing the accumulator, the bits carried from limb 'd4' to limb 'h0' fit in a 32-bit integer. This is true for poly1305-generic which processes only one block at a time. However, it's not true for the AVX2 implementation, which processes 4 blocks at a time and therefore can produce intermediate … [View More]limbs about 4x larger. Fix it by making the relevant calculations use 64-bit arithmetic rather than 32-bit. Note that most of the carries already used 64-bit arithmetic, but the d4 -> h0 carry was different for some reason. To be safe I also made the same change to the corresponding SSE2 code, though that only operates on 1 or 2 blocks at a time. I don't think it's really needed for poly1305_block_sse2(), but it doesn't hurt because it's already x86_64 code. It *might* be needed for poly1305_2block_sse2(), but overflows aren't easy to reproduce there. This bug was originally detected by my patches that improve testmgr to fuzz algorithms against their generic implementation. But also add a test vector which reproduces it directly (in the AVX2 case).

From: Eric Biggers <ebiggers(a)google.com> skcipher_walk_done() assumes it's a bug if, after the "slow" path is executed where the next chunk of data is processed via a bounce buffer, the algorithm says it didn't process all bytes. Thus it WARNs on this. However, this can happen legitimately when the message needs to be evenly divisible into "blocks" but isn't, and the algorithm has a 'walksize' greater than the block size. For example, ecb-aes-neonbs sets 'walksize' to 128 bytes and … [View More]
