| * | | crypto: cast5 - add x86_64/avx assembler implementationJohannes Goetzfried2012-08-012-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a x86_64/avx assembler implementation of the Cast5 block cipher. The implementation processes sixteen blocks in parallel (four 4 block chunk AVX operations). The table-lookups are done in general-purpose registers. For small blocksizes the functions from the generic module are called. A good performance increase is provided for blocksizes greater or equal to 128B. Patch has been tested with tcrypt and automated filesystem tests. Tcrypt benchmark results: Intel Core i5-2500 CPU (fam:6, model:42, step:7) cast5-avx-x86_64 vs. cast5-generic 64bit key: size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec 16B 0.99x 0.99x 1.00x 1.00x 1.02x 1.01x 64B 1.00x 1.00x 0.98x 1.00x 1.01x 1.02x 256B 2.03x 2.01x 0.95x 2.11x 2.12x 2.13x 1024B 2.30x 2.24x 0.95x 2.29x 2.35x 2.35x 8192B 2.31x 2.27x 0.95x 2.31x 2.39x 2.39x 128bit key: size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec 16B 0.99x 0.99x 1.00x 1.00x 1.01x 1.01x 64B 1.00x 1.00x 0.98x 1.01x 1.02x 1.01x 256B 2.17x 2.13x 0.96x 2.19x 2.19x 2.19x 1024B 2.29x 2.32x 0.95x 2.34x 2.37x 2.38x 8192B 2.35x 2.32x 0.95x 2.35x 2.39x 2.39x Signed-off-by: Johannes Goetzfried <Johannes.Goetzfried@informatik.stud.uni-erlangen.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * | | crypto: cleanup - remove unneeded crypto_alg.cra_list initializationsJussi Kivilinna2012-08-0115-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/'.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.

|/ | | | | | | | | | | | | | | | | | The authenc code doesn't deal with zero-length associated data correctly and ends up constructing a zero-length sg entry which causes a crash when it's fed into the crypto system. This patch fixes this by avoiding the code-path that triggers the SG construction if we have no associated data. This isn't the most optimal fix as it means that we'll end up using the fallback code-path even when we could still execute the digest function. However, this isn't a big deal as nobody but the test path would supply zero-length associated data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been observed that sometimes the crypto allocation code will get stuck for 60 seconds or multiples thereof. This is usually caused by an algorithm failing to pass the self-test. If an algorithm fails to be constructed, we will immediately notify all larval waiters. However, if it succeeds in construction, but then fails the self-test, we won't notify anyone at all. This patch fixes this by merging the notification in the case where the algorithm fails to be constructed with that of the the case where it pases the self-test. This way regardless of what happens, we'll give the larval waiters an answer. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently arc4.c provides simple one-byte blocksize cipher which is wrapped by ecb() module, giving function call overhead on every encrypted byte.

The implementation is very similar to the sse2 implementation and processes eight blocks in parallel. Because of the new non-destructive three operand syntax all move-instructions can be removed and therefore a little performance increase is provided. Patch has been tested with tcrypt and automated filesystem tests.

The implementation processes eight blocks in parallel (two 4 block chunk AVX operations). The table-lookups are done in general-purpose registers. For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way module are called. A good performance increase is provided for blocksizes greater or equal to 128B.
