2017-12-21crypto: Add a flag to identify crypto instancesSteffen Klassert
The upcomming crypto user configuration api needs to identify crypto instances. This patch adds a flag that is set if the algorithm is an instance that is build from templates.

The list_empty case in crypto_alg_match() will return without calling up_read() on crypto_alg_sem. We could do the "goto out" routine, but the function will clearly do the right thing with that test simply removed.

2012-02-09crypto: sha512 - reduce stack usage to safe numberAlexey Dobriyan
commit 51fc6dc8f948047364f7d42a4ed89b416c6cc0a3 upstream. For rounds 16--79, W[i] only depends on W[i - 2], W[i - 7], W[i - 15] and W[i - 16]. Consequently, keeping all W[80] array on stack is unnecessary, only 16 values are really needed. Using W[16] instead of W[80] greatly reduces stack usage (~750 bytes to ~340 bytes on x86_64). Line by line explanation: * BLEND_OP array is "circular" now, all indexes have to be modulo 16. Round number is positive, so remainder operation should be without surprises. * initial full message scheduling is trimmed to first 16 values which come from data block, the rest is calculated before it's needed. * original loop body is unrolled version of new SHA512_0_15 and SHA512_16_79 macros, unrolling was done to not do explicit variable renaming. Otherwise it's the very same code after preprocessing. See sha1_transform() code which does the same trick. Patch survives in-tree crypto test and original bugreport test (ping flood with hmac(sha512).

2012-02-09crypto: sha512 - make it work, undo percpu message scheduleAlexey Dobriyan
commit 84e31fdb7c797a7303e0cc295cb9bc8b73fb872d upstream. commit f9e2bca6c22d75a289a349f869701214d63b5060 aka "crypto: sha512 - Move message schedule W[80] to static percpu area" created global message schedule area. If sha512_update will ever be entered twice, hash will be silently calculated incorrectly. Probably the easiest way to notice incorrect hashes being calculated is to run 2 ping floods over AH with hmac(sha512): #!/usr/sbin/setkey -f flush; spdflush; add IP1 IP2 ah 25 -A hmac-sha512 0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000025; add IP2 IP1 ah 52 -A hmac-sha512 0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000052; spdadd IP1 IP2 any -P out ipsec ah/transport//require; spdadd IP2 IP1 any -P in ipsec ah/transport//require; XfrmInStateProtoError will start ticking with -EBADMSG being returned from ah_input(). This never happens with, say, hmac(sha1). With patch applied (on BOTH sides), XfrmInStateProtoError does not tick with multiple bidirectional ping flood streams like it doesn't tick with SHA-1. After this patch sha512_transform() will start using ~750 bytes of stack on x86_64. This is OK for simple loads, for something more heavy, stack reduction will be done separatedly.

commit b2bac6acf86d05d8af0499f37d91ecac15722803 upstream. As cryptd is depeneded on by other algorithms such as aesni-intel, it needs to be registered before them.

2011-10-21crypto: ghash - Avoid null pointer dereference if no key is setNick Bowler
The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

2011-07-08crypto: gf128mul - fix call to memset()Mathias Krause
In gf128mul_lle() and gf128mul_bbe() r isn't completely initialized with zero because the size argument passed to memset() is the size of the pointer, not the structure it points to. Luckily there are no in-kernel users of those functions so the ABI change implied by this fix should break no existing code. Based on a patch by the PaX Team.

2011-06-30crypto: testmgr - add xts-aes-256 self-testJarod Wilson
FIPS compliance requires a known-answer self-test for all approved cipher and mode combinations, for all valid key sizes. Presently, there are only self-tests for xts-aes-128. This adds a 256-bit one, pulled from the same reference document, which should satisfy the requirement.

2011-06-21net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-16crypto: aesni-intel - Merge with fpu.koAndy Lutomirski
Loading fpu without aesni-intel does nothing. Loading aesni-intel without fpu causes modes like xts to fail. (Unloading aesni-intel will restore those modes.) One solution would be to make aesni-intel depend on fpu, but it seems cleaner to just combine the modules.

2011-03-22zlib: slim down zlib_deflate() workspace when possibleJim Keniston
Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level.
