While working with some FIPS RNGVS test vectors yesterday, I discovered a little bug in the way the ansi_cprng code works right now. For example, the following test vector (complete with expected result) from http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf ... Key = f3b1666d13607242ed061cabb8d46202 DT = e6b3be782a23fa62d71d4afbb0e922fc V = f0000000000000000000000000000000 R = 88dda456302423e5f69da57e7b95c73a ...when run through ansi_cprng, yields an incorrect R value of e2afe0d794120103d6e86a2b503bdfaa. If I load up ansi_cprng w/dbg=1 though, it was fairly obvious what was going wrong: ----8<---- getting 16 random bytes for context ffff810033fb2b10 Calling _get_more_prng_bytes for context ffff810033fb2b10 Input DT: 00000000: e6 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc Input I: 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Input V: 00000000: f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 tmp stage 0: 00000000: e6 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc tmp stage 1: 00000000: f4 8e cb 25 94 3e 8c 31 d6 14 cd 8a 23 f1 3f 84 tmp stage 2: 00000000: 8c 53 6f 73 a4 1a af d4 20 89 68 f4 58 64 f8 be Returning new block for context ffff810033fb2b10 Output DT: 00000000: e7 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc Output I: 00000000: 04 8e cb 25 94 3e 8c 31 d6 14 cd 8a 23 f1 3f 84 Output V: 00000000: 48 89 3b 71 bc e4 00 b6 5e 21 ba 37 8a 0a d5 70 New Random Data: 00000000: 88 dd a4 56 30 24 23 e5 f6 9d a5 7e 7b 95 c7 3a Calling _get_more_prng_bytes for context ffff810033fb2b10 Input DT: 00000000: e7 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc Input I: 00000000: 04 8e cb 25 94 3e 8c 31 d6 14 cd 8a 23 f1 3f 84 Input V: 00000000: 48 89 3b 71 bc e4 00 b6 5e 21 ba 37 8a 0a d5 70 tmp stage 0: 00000000: e7 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc tmp stage 1: 00000000: 80 6b 3a 8c 23 ae 8f 53 be 71 4c 16 fc 13 b2 ea tmp stage 2: 00000000: 2a 4d e1 2a 0b 58 8e e6 36 b8 9c 0a 26 22 b8 30 Returning new block for context ffff810033fb2b10 Output DT: 00000000: e8 b3 be 78 2a 23 fa 62 d7 1d 4a fb b0 e9 22 fc Output I: 00000000: c8 e2 01 fd 9f 4a 8f e5 e0 50 f6 21 76 19 67 9a Output V: 00000000: ba 98 e3 75 c0 1b 81 8d 03 d6 f8 e2 0c c6 54 4b New Random Data: 00000000: e2 af e0 d7 94 12 01 03 d6 e8 6a 2b 50 3b df aa returning 16 from get_prng_bytes in context ffff810033fb2b10 ----8<---- The expected result is there, in the first "New Random Data", but we're incorrectly making a second call to _get_more_prng_bytes, due to some checks that are slightly off, which resulted in our original bytes never being returned anywhere. One approach to fixing this would be to alter some byte_count checks in get_prng_bytes, but it would mean the last DEFAULT_BLK_SZ bytes would be copied a byte at a time, rather than in a single memcpy, so a slightly more involved, equally functional, and ultimately more efficient way of fixing this was suggested to me by Neil, which I'm submitting here.

This patch swaps the role of libcrc32c and crc32c. Previously the implementation was in libcrc32c and crc32c was a wrapper. Now the code is in crc32c and libcrc32c just calls the crypto layer. The reason for the change is to tap into the algorithm selection capability of the crypto API so that optimised implementations such as the one utilising Intel's CRC32C instruction can be used where available.

This patch makes /proc/crypto call the type-specific show function if one is present before calling the legacy show functions for cipher/digest/compress. This allows us to reuse the type values for those legacy types. In particular, hash and digest will share one type value while shash is phased in as the default hash type.

It is often useful to save the partial state of a hash function so that it can be used as a base for two or more computations. The most prominent example is HMAC where all hashes start from a base determined by the key. Having an import/export interface means that we only have to compute that base once rather than for each message. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

The shash interface replaces the current synchronous hash interface. It improves over hash in two ways. Firstly shash is reentrant, meaning that the same tfm may be used by two threads simultaneously as all hashing state is stored in a local descriptor. The other enhancement is that shash no longer takes scatter list entries. This is because shash is specifically designed for synchronous algorithms and as such scatter lists are unnecessary. All existing hash users will be converted to shash once the algorithms have been completely converted. There is also a new finup function that combines update with final. This will be extended to ahash once the algorithm conversion is done. This is also the first time that an algorithm type has their own registration function. Existing algorithm types will be converted to this way in due course. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch reintroduces a completely revamped crypto_alloc_tfm. The biggest change is that we now take two crypto_type objects when allocating a tfm, a frontend and a backend. In fact this simply formalises what we've been doing behind the API's back. For example, as it stands crypto_alloc_ahash may use an actual ahash algorithm or a crypto_hash algorithm. Putting this in the API allows us to do this much more cleanly. The existing types will be converted across gradually. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

The type exit function needs to undo any allocations done by the type init function. However, the type init function may differ depending on the upper-level type of the transform (e.g., a crypto_blkcipher instantiated as a crypto_ablkcipher). So we need to move the exit function out of the lower-level structure and into crypto_tfm itself. As it stands this is a no-op since nobody uses exit functions at all. However, all cases where a lower-level type is instantiated as a different upper-level type (such as blkcipher as ablkcipher) will be converted such that they allocate the underlying transform and use that instead of casting (e.g., crypto_ablkcipher casted into crypto_blkcipher). That will need to use a different exit function depending on the upper-level type. This patch also allows the type init/exit functions to call (or not) cra_init/cra_exit instead of always calling them from the top level. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This is a patch that was sent to me by Jarod Wilson, marking off my outstanding todo to allow the ansi cprng to set/reset the DT counter value in a cprng instance. Currently crytpo_rng_reset accepts a seed byte array which is interpreted by the ansi_cprng as a {V key} tuple. This patch extends that tuple to now be {V key DT}, with DT an optional value during reset. This patch also fixes a bug we noticed in which the offset of the key area of the seed is started at DEFAULT_PRNG_KSZ rather than DEFAULT_BLK_SZ as it should be.

Resetting the control word is quite expensive. Fortunately this isn't an issue for the common operations such as CBC and ECB as the whole operation is done through a single call. However, modes such as LRW and XTS have to call padlock over and over again for one operation which really hurts if each call resets the control word. This patch uses an idea by Sebastian Siewior to store the last control word used on a CPU and only reset the control word if that changes. Note that any task switch automatically resets the control word so we only need to be accurate with regard to the stored control word when no task switches occur.

The FIPS specification requires that should self test for any supported crypto algorithm fail during operation in fips mode, we need to prevent the use of any crypto functionality until such time as the system can be re-initialized.

SEC version 2.1 and above adds the capability to do the IPSec ICV memcmp in h/w. Results of the cmp are written back in the descriptor header, along with the done status. A new callback is added that checks these ICCR bits instead of performing the memcmp on the core, and is enabled by h/w capability. Signed-off-by: NKim Phillips <kim.phillips@freescale.com> After testing on different parts, another condition was added before using h/w auth check because different SEC revisions require different handling. The SEC 3.0 allows a more flexible link table where the auth data can span separate link table entries. The SEC 2.4/2.1 does not support this case. So a test was added in the decrypt routine for a fragmented case; the h/w auth check is disallowed for revisions not having the extent in the link table; in this case the hw auth check is done by software. A portion of a previous change for SEC 3.0 link table handling was removed since it became dead code with the hw auth check supported. This seems to be the best compromise for using hw auth check on supporting SEC revisions; it keeps the link table logic simpler for the fragmented cases.

there's a new ptrace arch level feature in .28: config X86_PTRACE_BTS bool "Branch Trace Store" it has broken fork() handling: the old DS area gets copied over into a new task without clearing it. Fixes exist but they came too late: c5dee617: x86, bts: memory accounting bf53de90: x86, bts: add fork and exit handling and are queued up for v2.6.29. This shows that the facility is still not tested well enough to release into a stable kernel - disable it for now and reactivate in .29. In .29 the hardware-branch-tracer will use the DS/BTS facilities too - hopefully resulting in better code. Signed-off-by: NIngo Molnar <mingo@elte.hu>

When deleting an edac device, we have to wait for its edac_dev.work to be completed before deleting the whole edac_dev structure. Since we have no idea which work in current edac_poller's workqueue is the work we are conerned about, we wait for all work in the edac_poller's workqueue to be proceseed. This is done via flush_cpu_workqueue() which inserts a wq_barrier into the tail of the workqueue and then sleeping on the completion of this wq_barrier. The edac_poller will wake up sleepers when it is found. EDAC core creates only one kernel worker thread, edac_poller, to run the works of all current edac devices. They share the same callback function of edac_device_workq_function(), which would grab the mutex of device_ctls_mutex first before it checks the device. This is exactly where edac_poller and rmmod would have a great chance to deadlock. In below call trace of rmmod > ... > edac_device_del_device > edac_device_workq_teardown > flush_workqueue > flush_cpu_workqueue, device_ctls_mutex would have already been grabbed by edac_device_del_device(). So, on one hand rmmod would sleep on the completion of a wq_barrier, holding device_ctls_mutex; on the other hand edac_poller would be blocked on the same mutex when it's running any one of works of existing edac evices(Note, this edac_dev.work is likely to be totally irrelevant to the one that is being removed right now)and never would have a chance to run the work of above wq_barrier to wake rmmod up. edac_device_workq_teardown() should not be called within the critical region of device_ctls_mutex. Just like is done in edac_pci_del_device() and edac_mc_del_mc(), where edac_pci_workq_teardown() and edac_mc_workq_teardown() are called after related mutex are released. Moreover, an edac_dev.work should check first if it is being removed. If this is the case, then it should bail out immediately. Since not all of existing edac devices are to be removed, this "shutting flag" should be contained to edac device being removed. The current edac_dev.op_state can be used to serve this purpose. The original deadlock problem and the solution have been witnessed and tested on actual hardware. Without the solution, rmmod an edac driver would result in below deadlock: root@localhost:/root> rmmod mv64x60_edac EDAC DEBUG: mv64x60_dma_err_remove() EDAC DEBUG: edac_device_del_device() EDAC DEBUG: find_edac_device_by_dev() (hang for a moment) INFO: task edac-poller:2030 blocked for more than 120 seconds.

During test of the w1-gpio driver i found that in "w1.c:679 w1_slave_found()" the device id is converted to little-endian with "cpu_to_le64()", but its not converted back to cpu format in "w1_io.c:293 w1_reset_select_slave()". Based on a patch created by Andreas Hummel.
