2013-05-24crypto: crct10dif - Simple correctness and speed test for CRCT10DIF hashTim Chen3-0/+51
These are simple tests to do sanity check of CRC T10 DIF hash. The correctness of the transform can be checked with the command modprobe tcrypt mode=47 The speed of the transform can be evaluated with the command modprobe tcrypt mode=320 Set the cpu frequency to constant and turn turbo off when running the speed test so the frequency governor will not tweak the frequency and affects the measurements.

2013-04-25crypto: camellia - add AVX2/AES-NI/x86_64 assembler implementation of ↵Jussi Kivilinna2-0/+35
camellia cipher Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring 32 parallel blocks for input (512 bytes). Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards. Even with this additional handling, performance should be higher compared to the AES-NI/AVX implementation.

Patch adds AVX2/x86-64 implementation of Serpent cipher, requiring 16 parallel blocks for input (256 bytes). Implementation is based on the AVX implementation and extends to use the 256-bit wide YMM registers. Since serpent does not use table look-ups, this implementation should be close to two times faster than the AVX implementation.

Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel blocks for input (256 bytes). Table look-ups are performed using vpgatherdd instruction directly from vector registers and thus should be faster than earlier implementations.

2013-04-22X.509: Support parse long form of length octets in Authority Key IdentifierChun-Yi Lee1-8/+47
Per X.509 spec in 4.2.1.1 section, the structure of Authority Key Identifier Extension is: AuthorityKeyIdentifier ::= SEQUENCE { keyIdentifier [0] KeyIdentifier OPTIONAL, authorityCertIssuer [1] GeneralNames OPTIONAL, authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL } KeyIdentifier ::= OCTET STRING When a certificate also provides authorityCertIssuer and authorityCertSerialNumber then the length of AuthorityKeyIdentifier SEQUENCE is likely to long form format. e.g. The example certificate demos/tunala/A-server.pem in openssl source: X509v3 Authority Key Identifier: keyid:49:FB:45:72:12:C4:CC:E1:45:A1:D3:08:9E:95:C4:2C:6D:55:3F:17 DirName:/C=NZ/L=Wellington/O=Really Irresponsible Authorisation Authority (RIAA)/OU=Cert-stamping/CN=Jackov al-Trades/emailAddress=none@fake.domain serial:00 Current parsing rule of OID_authorityKeyIdentifier only take care the short form format, it causes load certificate to modsign_keyring fail: [ 12.061147] X.509: Extension: 47 [ 12.075121] MODSIGN: Problem loading in-kernel X.509 certificate (-74) So, this patch add the parsing rule for support long form format against Authority Key Identifier. v3: Changed the size check in "Short Form length" case, we allow v[3] smaller then (vlen - 4) because authorityCertIssuer and authorityCertSerialNumber are also possible attach in AuthorityKeyIdentifier sequence. v2: - Removed comma from author's name. - Moved 'Short Form length' comment inside the if-body. - Changed the type of sub to size_t. - Use ASN1_INDEFINITE_LENGTH rather than writing 0x80 and 127. - Moved the key_len's value assignment before alter v. - Fixed the typo of octets. - Add 2 to v before entering the loop for calculate the length. - Removed the comment of check vlen.

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin1-3/+3
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2013-02-19crypto: user - fix info leaks in report APIMathias Krause8-30/+29
Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

2013-01-08crypto: ctr - make rfc3686 asynchronous block cipherJussi Kivilinna3-63/+115
Some hardware crypto drivers register asynchronous ctr(aes), which is left unused in IPSEC because rfc3686 template only supports synchronous block ciphers. Some other drivers register rfc3686(ctr(aes)) to workaround this limitation but not all. This patch changes rfc3686 to use asynchronous block ciphers, to allow async ctr(aes) algorithms to be utilized automatically by IPSEC.

When in fips mode, compression algoritms fails to initialize, e.g. modprobe ubifs returns UBIFS error: compr_init: cannot initialize compressor lzo, error -2 FIPS mode should not care about compression algoritms at all. Patch just set fips_enabled flag to 1 to all compression algorithms managed by testmgr. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

camellia cipher This patch adds AES-NI/AVX/x86_64 assembler implementation of Camellia block cipher. Implementation process data in sixteen block chunks, which are byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre- and post-filtering.

corruption cryptd_queue_worker attempts to prevent simultaneous accesses to crypto workqueue by cryptd_enqueue_request using preempt_disable/preempt_enable. However cryptd_enqueue_request might be called from softirq context, so add local_bh_disable/local_bh_enable to prevent data corruption and panics.
