crypto: testmgr - Pad aes_ccm_enc_tv_template vector

2017-03-12T05:44:14+00:00

commit 1c68bb0f62bf8de8bb30123ea840d5168f25abea upstream. Running with KASAN and crypto tests currently gives BUG: KASAN: global-out-of-bounds in __test_aead+0x9d9/0x2200 at addr ffffffff8212fca0 Read of size 16 by task cryptomgr_test/1107 Address belongs to variable 0xffffffff8212fca0 CPU: 0 PID: 1107 Comm: cryptomgr_test Not tainted 4.10.0+ #45 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.9.1-1.fc24 04/01/2014 Call Trace: dump_stack+0x63/0x8a kasan_report.part.1+0x4a7/0x4e0 ? __test_aead+0x9d9/0x2200 ? crypto_ccm_init_crypt+0x218/0x3c0 [ccm] kasan_report+0x20/0x30 check_memory_region+0x13c/0x1a0 memcpy+0x23/0x50 __test_aead+0x9d9/0x2200 ? kasan_unpoison_shadow+0x35/0x50 ? alg_test_akcipher+0xf0/0xf0 ? crypto_skcipher_init_tfm+0x2e3/0x310 ? crypto_spawn_tfm2+0x37/0x60 ? crypto_ccm_init_tfm+0xa9/0xd0 [ccm] ? crypto_aead_init_tfm+0x7b/0x90 ? crypto_alloc_tfm+0xc4/0x190 test_aead+0x28/0xc0 alg_test_aead+0x54/0xd0 alg_test+0x1eb/0x3d0 ? alg_find_test+0x90/0x90 ? __sched_text_start+0x8/0x8 ? __wake_up_common+0x70/0xb0 cryptomgr_test+0x4d/0x60 kthread+0x173/0x1c0 ? crypto_acomp_scomp_free_ctx+0x60/0x60 ? kthread_create_on_node+0xa0/0xa0 ret_from_fork+0x2c/0x40 Memory state around the buggy address: ffffffff8212fb80: 00 00 00 00 01 fa fa fa fa fa fa fa 00 00 00 00 ffffffff8212fc00: 00 01 fa fa fa fa fa fa 00 00 00 00 01 fa fa fa >ffffffff8212fc80: fa fa fa fa 00 05 fa fa fa fa fa fa 00 00 00 00 ^ ffffffff8212fd00: 01 fa fa fa fa fa fa fa 00 00 00 00 01 fa fa fa ffffffff8212fd80: fa fa fa fa 00 00 00 00 00 05 fa fa fa fa fa fa This always happens on the same IV which is less than 16 bytes. Per Ard, "CCM IVs are 16 bytes, but due to the way they are constructed internally, the final couple of bytes of input IV are dont-cares. Apparently, we do read all 16 bytes, which triggers the KASAN errors." Fix this by padding the IV with null bytes to be at least 16 bytes.

crypto: testmgr - add/enhance test cases for CRC-T10DIF

2016-12-07T12:01:15+00:00

The existing test cases only exercise a small slice of the various possible code paths through the x86 SSE/PCLMULQDQ implementation, and the upcoming ports of it for arm64. So add one that exceeds 256 bytes in size, and convert another to a chunked test. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: FIPS - allow tests to be disabled in FIPS mode

2016-08-31T15:21:25+00:00

In FIPS mode, additional restrictions may apply. If these restrictions are violated, the kernel will panic(). This patch allows test vectors for symmetric ciphers to be marked as to be skipped in FIPS mode. Together with the patch, the XTS test vectors where the AES key is identical to the tweak key is disabled in FIPS mode. This test vector violates the FIPS requirement that both keys must be different. Reported-by: Tapas Sarangi Signed-off-by: Stephan Mueller Signed-off-by: Herbert Xu
