2018-05-30qtnfmac: cleanup wdev structure between its usesSergey Matyukevich
Driver uses statically allocated wdev structures for each virtual interface. However wdev structure is not properly cleaned up between its uses. As a result, various bugs appear when userspace tools like hostapd were not gracefully stopped. In particular, this commit fixes the following issue: - start hostapd with more than 2 mBSS - kill hostapd using SIGKILL - start again hostapd with more than 2 mBSS However only two mBSS entities will be started: primary and the last BSS listed in hostapd config.

2018-05-30perf cs-etm: Fix indexing for decoder packet queueMathieu Poirier
The tail of a queue is supposed to be pointing to the next available slot in a queue. In this implementation the tail is incremented before it is used and as such points to the last used element, something that has the immense advantage of centralizing tail management at a single location and eliminating a lot of redundant code. But this needs to be taken into consideration on the dequeueing side where the head also needs to be incremented before it is used, or the first available element of the queue will be skipped.

2018-05-30nbd: clear DISCONNECT_REQUESTED flag once disconnection occurs.Kevin Vigor
When a userspace client requests a NBD device be disconnected, the DISCONNECT_REQUESTED flag is set. While this flag is set, the driver will not inform userspace when a connection is closed. Unfortunately the flag was never cleared, so once a disconnect was requested the driver would thereafter never tell userspace about a closed connection. Thus when connections failed due to timeout, no attempt to reconnect was made and eventually the device would fail. Fix by clearing the DISCONNECT_REQUESTED flag (and setting the DISCONNECTED flag) once all connections are closed.

2018-05-30btrfs: Factor out write portion of btrfs_get_blocks_directNikolay Borisov
Now that the read side is extracted into its own function, do the same to the write side. This leaves btrfs_get_blocks_direct_write with the sole purpose of handling common locking required. Also flip the condition in btrfs_get_blocks_direct_write so that the write case comes first and we check for if (Create) rather than if (!create). This is purely subjective but I believe makes reading a bit more "linear". No functional changes. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
2018-05-30btrfs: Factor out read portion of btrfs_get_blocks_directNikolay Borisov
Currently this function handles both the READ and WRITE dio cases. This is facilitated by a bunch of 'if' statements, a goto short-circuit statement and a very perverse aliasing of "!created"(READ) case by setting lockstart = lockend and checking for lockstart < lockend for detecting the write. Let's simplify this mess by extracting the READ-only code into a separate __btrfs_get_block_direct_read function. This is only the first step, the next one will be to factor out the write side as well. The end goal will be to have the common locking/ unlocking code in btrfs_get_blocks_direct and then it will call either the read|write subvariants. No functional changes.

2018-05-30block: kyber: make kyber more friendly with mergingJianchao Wang
Currently, kyber is very unfriendly with merging. kyber depends on ctx rq_list to do merging, however, most of time, it will not leave any requests in ctx rq_list. This is because even if tokens of one domain is used up, kyber will try to dispatch requests from other domain and flush the rq_list there. To improve this, we setup kyber_ctx_queue (kcq) which is similar with ctx, but it has rq_lists for different domain and build same mapping between kcq and khd as the ctx & hctx. Then we could merge, insert and dispatch for different domains separately. At the same time, only flush the rq_list of kcq when get domain token successfully. Then if one domain token is used up, the requests could be left in the rq_list of that domain and maybe merged with following io.

2018-05-31crypto: x86/salsa20 - remove x86 salsa20 implementationsEric Biggers
The x86 assembly implementations of Salsa20 use the frame base pointer register (%ebp or %rbp), which breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. Recent (v4.10+) kernels will warn about this, e.g. WARNING: kernel stack regs at 00000000a8291e69 in syzkaller047086:4677 has bad 'bp' value 000000001077994c [...] But after looking into it, I believe there's very little reason to still retain the x86 Salsa20 code. First, these are *not* vectorized (SSE2/SSSE3/AVX2) implementations, which would be needed to get anywhere close to the best Salsa20 performance on any remotely modern x86 processor; they're just regular x86 assembly. Second, it's still unclear that anyone is actually using the kernel's Salsa20 at all, especially given that now ChaCha20 is supported too, and with much more efficient SSSE3 and AVX2 implementations. Finally, in benchmarks I did on both Intel and AMD processors with both gcc 8.1.0 and gcc 4.9.4, the x86_64 salsa20-asm is actually slightly *slower* than salsa20-generic (~3% slower on Skylake, ~10% slower on Zen), while the i686 salsa20-asm is only slightly faster than salsa20-generic (~15% faster on Skylake, ~20% faster on Zen). The gcc version made little difference. So, the x86_64 salsa20-asm is pretty clearly useless. That leaves just the i686 salsa20-asm, which based on my tests provides a 15-20% speed boost. But that's without updating the code to not use %ebp. And given the maintenance cost, the small speed difference vs. salsa20-generic, the fact that few people still use i686 kernels, the doubt that anyone is even using the kernel's Salsa20 at all, and the fact that a SSE2 implementation would almost certainly be much faster on any remotely modern x86 processor yet no one has cared enough to add one yet, I don't think it's worthwhile to keep. Thus, just remove both the x86_64 and i686 salsa20-asm implementations.

In some cases the CCB DMA-based internal transfer started by the MOVE command (src=M3 register, dst=descriptor buffer) does not finish in time and DECO executes the unpatched descriptor. This leads eventually to a DECO Watchdog Timer timeout error. To make sure the transfer ends, change the MOVE command to be blocking.

Management Complex (MC) f/w detection is based on CTPR_MS[DPAA2] bit. This is incorrect since: -the bit is set for all CAAM blocks integrated in SoCs with a certain Layerscape Chassis -some SoCs with LS Chassis don't have an MC block (thus no MC f/w) To fix this, MC f/w detection will be based on the presence of "fsl,qoriq-mc" compatible string in the device tree.

2018-05-31crypto: clarify licensing of OpenSSL asm codeAdam Langley
Several source files have been taken from OpenSSL. In some of them a comment that "permission to use under GPL terms is granted" was included below a contradictory license statement. In several cases, there was no indication that the license of the code was compatible with the GPLv2. This change clarifies the licensing for all of these files. I've confirmed with the author (Andy Polyakov) that a) he has licensed the files with the GPLv2 comment under that license and b) that he's also happy to license the other files under GPLv2 too. In one case, the file is already contained in his CRYPTOGAMS bundle, which has a GPLv2 option, and so no special measures are needed. In all cases, the license status of code has been clarified by making the GPLv2 license prominent. The .S files have been regenerated from the updated .pl files. This is a comment-only change. No code is changed. Signed-off-by: Adam Langley <agl@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Commit 56e8e57fc3a7 ("crypto: morus - Add common SIMD glue code for MORUS") accidetally consiedered the glue code to be usable by different architectures, but it seems to be only usable on x86. This patch moves it under arch/x86/crypto and adds 'depends on X86' to the Kconfig options and also removes the prompt to hide these internal options from the user.

2018-05-31crypto: testmgr - eliminate redundant decryption test vectorsEric Biggers
Currently testmgr has separate encryption and decryption test vectors for symmetric ciphers. That's massively redundant, since with few exceptions (mostly mistakes, apparently), all decryption tests are identical to the encryption tests, just with the input/result flipped. Therefore, eliminate the redundancy by removing the decryption test vectors and updating testmgr to test both encryption and decryption using what used to be the encryption test vectors. Naming is adjusted accordingly: each cipher_testvec now has a 'ptext' (plaintext), 'ctext' (ciphertext), and 'len' instead of an 'input', 'result', 'ilen', and 'rlen'. Note that it was always the case that 'ilen == rlen'. AES keywrap ("kw(aes)") is special because its IV is generated by the encryption. Previously this was handled by specifying 'iv_out' for encryption and 'iv' for decryption. To make it work cleanly with only one set of test vectors, put the IV in 'iv', remove 'iv_out', and add a boolean that indicates that the IV is generated by the encryption. In total, this removes over 10000 lines from testmgr.h, with no reduction in test coverage since prior patches already copied the few unique decryption test vectors into the encryption test vectors. This covers all algorithms that used 'struct cipher_testvec', e.g. any block cipher in the ECB, CBC, CTR, XTS, LRW, CTS-CBC, PCBC, OFB, or keywrap modes, and Salsa20 and ChaCha20. No change is made to AEAD tests, though we probably can eliminate a similar redundancy there too. The testmgr.h portion of this patch was automatically generated using the following awk script, with some slight manual fixups on top (updated 'struct cipher_testvec' definition, updated a few comments, and fixed up the AES keywrap test vectors): BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER } /^static const struct cipher_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC } /^static const struct cipher_testvec.*_dec_/ { mode = DECVEC } mode == ENCVEC && !/\.ilen[[:space:]]*=/ { sub(/\.input[[:space:]]*=$/, ".ptext =") sub(/\.input[[:space:]]*=/, ".ptext\t=") sub(/\.result[[:space:]]*=$/, ".ctext =") sub(/\.result[[:space:]]*=/, ".ctext\t=") sub(/\.rlen[[:space:]]*=/, ".len\t=") print } mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER } mode == OTHER { print } mode == ENCVEC && /^};/ { mode = OTHER } mode == DECVEC && /^};/ { mode = DECVEC_TAIL } Note that git's default diff algorithm gets confused by the testmgr.h portion of this patch, and reports too many lines added and removed. It's better viewed with 'git diff --minimal' (or 'git show --minimal'), which reports "2 files changed, 919 insertions(+), 11723 deletions(-)".
