* crypto: api - Use formatting of module nameAlex Riesen2009-06-021-6/+3

* crypto: testmgr - Allow hash test vectors longer than a pageHerbert Xu2009-06-021-3/+8
| | | | | | | | | | | As it stands we will each test hash vector both linearly and as a scatter list if applicable. This means that we cannot have vectors longer than a page, even with scatter lists. This patch fixes this by skipping test vectors with np != 0 when testing linearly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Check all test vector lengthsHerbert Xu2009-06-021-0/+25
| | | | | | | | | | As we cannot guarantee the availability of contiguous pages at run-time, all test vectors must either fit within a page, or use scatter lists. In some cases vectors were not checked as to whether they fit inside a page. This patch adds all the missing checks. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hifn_795x - fix __dev{init,exit} markingsMike Frysinger2009-06-021-4/+4
| | | | | | | | | | | | | | The remove member of the pci_driver hifn_pci_driver uses __devexit_p(), so the remove function itself should be marked with __devexit. And where there be __devexit on the remove, so is there __devinit on the probe. Similarly, the module_init/module_exit functions should be declared with plain __init/__exit markings, not the hotplug __dev{init,exit} ones.

* crypto: tcrypt - Do not exit on success in fips modeJarod Wilson2009-06-021-74/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | At present, the tcrypt module always exits with an -EAGAIN upon successfully completing all the tests its been asked to run. In fips mode, integrity checking is done by running all self-tests from the initrd, and its much simpler to check the ret from modprobe for success than to scrape dmesg and/or /proc/crypto. Simply stay loaded, giving modprobe a retval of 0, if self-tests all pass and we're in fips mode. A side-effect of tracking success/failure for fips mode is that in non-fips mode, self-test failures will return the actual failure return codes, rather than always returning -EAGAIN, which seems more correct anyway. The tcrypt_test() portion of the patch is dependent on my earlier pair of patches that skip non-fips algs in fips mode, at least to achieve the fully intended behavior. Nb: testing this patch against the cryptodev tree revealed a test failure for sha384, which I have yet to look into...

* crypto: testmgr - Skip algs not flagged fips_allowed in fips modeJarod Wilson2009-06-021-0/+8
| | | | | | | | | | | Because all fips-allowed algorithms must be self-tested before they can be used, they will all have entries in testmgr.c's alg_test_descs[].

* crypto: testmgr - Mark algs allowed in fips modeJarod Wilson2009-06-021-0/+23
| | | | | | | | | | | | | | | | | | | | | | Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs that are allowed to be used when in fips mode. One caveat: des isn't actually allowed anymore, but des (and thus also ecb(des)) has to be permitted, because disallowing them results in des3_ede being unable to properly register (see des module init func). Also, crc32 isn't technically on the fips approved list, but I think it gets used in various places that necessitate it being allowed. This list is based on http://csrc.nist.gov/groups/STM/cavp/index.html Important note: allowed/approved here does NOT mean "validated", just that its an alg that *could* be validated.

* crypto: testmgr - Dynamically allocate xbuf and axbufHerbert Xu2009-06-023-68/+61
| | | | | | | | | | | | | | | | | | | We currently allocate temporary memory that is used for testing statically. This renders the testing engine non-reentrant. As algorithms may nest, i.e., one may construct another in order to carry out a part of its operation, this is unacceptable. For example, it has been reported that an AEAD implementation allocates a cipher in its setkey function, which causes it to fail during testing as the temporary memory is overwritten. This patch replaces the static memory with dynamically allocated buffers. We need a maximum of 16 pages so this slightly increases the chances of an algorithm failing due to memory shortage. However, as testing usually occurs at registration, this shouldn't be a big problem. Reported-by: Shasi Pulijala <spulijala@amcc.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Print self-test pass notices in fips modeJarod Wilson2009-06-021-0/+4
| | | | | | | | | | | | | | | | | | | According to our FIPS CAVS testing lab guru, when we're in fips mode, we must print out notices of successful self-test completion for every alg to be compliant. New and improved v2, without strncmp crap. Doesn't need to touch a flag though, due to not moving the notest label around anymore. Applies atop '[PATCH v2] crypto: catch base cipher self-test failures in fips mode'. Personally, I wouldn't mind seeing this info printed out regardless of whether or not we're in fips mode, I think its useful info, but will stick with only in fips mode for now.

Test vectors all come from sample FIPS CAVS files provided to Red Hat by a testing lab. Unfortunately, all the published sample vectors in RFC 3610 and NIST Special Publication 800-38C contain nonce lengths that the kernel's rfc4309 implementation doesn't support, so while using some public domain vectors would have been preferred, its not possible at this time.

| | | | | | | | | | | | | | | | | | | | | A pointer to omap_rng_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

* crypto: aes-ni - Add support for more modesHuang Ying2009-06-022-1/+271
| | | | | | | | | | | | | | | | | | | | | | | | Because kernel_fpu_begin() and kernel_fpu_end() operations are too slow, the performance gain of general mode implementation + aes-aesni is almost all compensated. The AES-NI support for more modes are implemented as follow: - Add a new AES algorithm implementation named __aes-aesni without kernel_fpu_begin/end() - Use fpu(<mode>(AES)) to provide kenrel_fpu_begin/end() invoking - Add <mode>(AES) ablkcipher, which uses cryptd(fpu(<mode>(AES))) to defer cryption to cryptd context in soft_irq context. Now the ctr, lrw, pcbc and xts support are added. Performance testing based on dm-crypt shows that cryption time can be reduced to 50% of general mode implementation + aes-aesni implementation.

| | | | | | | | | | | | | | | | | A quirk that we've always supported is having an sg entry that's bigger than a page, or more generally an sg entry that crosses page boundaries. Even though it would be better to explicitly have to sg entries for this, we need to support it for the existing users, in particular, IPsec. The new ahash sg walking code did try to handle this, but there was a bug where we didn't increment the page so kept on walking on the first page over an dover again. This patch fixes it.

The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

If not, the isp1760_urb_done function doesn't get called for the URB and the process trying to free it hangs forever on a wait_queue. This patch does two things. If the URB being dequeued has others queued behind it, it re-queues them. And it searches the queues looking for the URB being dequeued rather than just looking at the one at the front of the queue.

| * | svcrdma: dma unmap the correct length for the RPCRDMA header page.Steve Wise2009-05-272-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The svcrdma module was incorrectly unmapping the RPCRDMA header page. On IBM pserver systems this causes a resource leak that results in running out of bus address space (10 cthon iterations will reproduce it). The code was mapping the full page but only unmapping the actual header length. The fix is to only map the header length. I also cleaned up the use of ib_dma_map_page() calls since the unmap logic always uses ib_dma_unmap_single(). I made these symmetrical.
