2017-07-18hwrng: remember rng chosen by userHarald Freudenberger1-2/+19
When a user chooses a rng source via sysfs attribute this rng should be sticky, even when other sources with better quality to register. This patch introduces a simple way to remember the user's choice. This is reflected by a new sysfs attribute file 'rng_selected' which shows if the current rng has been chosen by userspace. The new attribute file shows '1' for user selected rng and '0' otherwise.

2017-07-18hwrng: use rng source with best qualityHarald Freudenberger1-6/+19
This patch rewoks the hwrng to always use the rng source with best entropy quality. On registation and unregistration the hwrng now tries to choose the best (= highest quality value) rng source. The handling of the internal list of registered rng sources is now always sorted by quality and the top most rng chosen.

2017-07-18crypto: caam/qi - handle large number of S/Gs caseHoria Geantă3-4/+34
For more than 16 S/G entries, driver currently corrupts memory on ARMv8, see below KASAN log. Note: this does not reproduce on PowerPC due to different (smaller) cache line size - 64 bytes on PPC vs. 128 bytes on ARMv8. One such use case is one of the cbc(aes) test vectors - with 8 S/G entries and src != dst. Driver needs 1 (IV) + 2 x 8 = 17 entries, which goes over the 16 S/G entries limit: (CAAM_QI_MEMCACHE_SIZE - offsetof(struct ablkcipher_edesc, sgt)) / sizeof(struct qm_sg_entry) = 256 / 16 = 16 S/Gs Fix this by: -increasing object size in caamqicache pool from 512 to 768; this means the maximum number of S/G entries grows from (at least) 16 to 32 (again, for ARMv8 case of 128-byte cache line) -add checks in the driver to fail gracefully (ENOMEM) in case the 32 S/G entries limit is exceeded ================================================================== BUG: KASAN: slab-out-of-bounds in ablkcipher_edesc_alloc+0x4ec/0xf60 Write of size 1 at addr ffff800021cb6003 by task cryptomgr_test/1394 CPU: 3 PID: 1394 Comm: cryptomgr_test Not tainted 4.12.0-rc7-next-20170703-00023-g72badbcc1ea7-dirty #26 Hardware name: LS1046A RDB Board (DT) Call trace: [<ffff20000808ac6c>] dump_backtrace+0x0/0x290 [<ffff20000808b014>] show_stack+0x14/0x1c [<ffff200008d62c00>] dump_stack+0xa4/0xc8 [<ffff200008264e40>] print_address_description+0x110/0x26c [<ffff200008265224>] kasan_report+0x1d0/0x2fc [<ffff2000082637b8>] __asan_store1+0x4c/0x54 [<ffff200008b4884c>] ablkcipher_edesc_alloc+0x4ec/0xf60 [<ffff200008b49304>] ablkcipher_encrypt+0x44/0xcc [<ffff20000848a61c>] skcipher_encrypt_ablkcipher+0x120/0x138 [<ffff200008495014>] __test_skcipher+0xaec/0xe30 [<ffff200008497088>] test_skcipher+0x6c/0xd8 [<ffff200008497154>] alg_test_skcipher+0x60/0xe4 [<ffff2000084974c4>] alg_test.part.13+0x130/0x304 [<ffff2000084976d4>] alg_test+0x3c/0x68 [<ffff2000084938ac>] cryptomgr_test+0x54/0x5c [<ffff20000810276c>] kthread+0x188/0x1c8 [<ffff2000080836c0>] ret_from_fork+0x10/0x50 Allocated by task 1394: save_stack_trace_tsk+0x0/0x1ac save_stack_trace+0x18/0x20 kasan_kmalloc.part.5+0x48/0x110 kasan_kmalloc+0x84/0xa0 kasan_slab_alloc+0x14/0x1c kmem_cache_alloc+0x124/0x1e8 qi_cache_alloc+0x28/0x58 ablkcipher_edesc_alloc+0x244/0xf60 ablkcipher_encrypt+0x44/0xcc skcipher_encrypt_ablkcipher+0x120/0x138 __test_skcipher+0xaec/0xe30 test_skcipher+0x6c/0xd8 alg_test_skcipher+0x60/0xe4 alg_test.part.13+0x130/0x304 alg_test+0x3c/0x68 cryptomgr_test+0x54/0x5c kthread+0x188/0x1c8 ret_from_fork+0x10/0x50 Freed by task 0: (stack is not available) The buggy address belongs to the object at ffff800021cb5e00 which belongs to the cache caamqicache of size 512 The buggy address is located 3 bytes to the right of 512-byte region [ffff800021cb5e00, ffff800021cb6000) The buggy address belongs to the page: page:ffff7e0000872d00 count:1 mapcount:0 mapping: (null) index:0x0 compound_mapcount: 0 flags: 0xfffc00000008100(slab|head) raw: 0fffc00000008100 0000000000000000 0000000000000000 0000000180190019 raw: dead000000000100 dead000000000200 ffff800931268200 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff800021cb5f00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffff800021cb5f80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >ffff800021cb6000: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ^ ffff800021cb6080: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ffff800021cb6100: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ================================================================== Fixes: b189817cf789 ("crypto: caam/qi - add ablkcipher and authenc algorithms") Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2017-07-15random: suppress spammy warnings about unseeded randomnessTheodore Ts'o1-17/+39
Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by: Theodore Ts'o <tytso@mit.edu>
