crypto: skcipher - remove the "blkcipher" algorithm type

2019-11-01T05:38:32+00:00

Now that all "blkcipher" algorithms have been converted to "skcipher", remove the blkcipher algorithm type. The skcipher (symmetric key cipher) algorithm type was introduced a few years ago to replace both blkcipher and ablkcipher (synchronous and asynchronous block cipher). The advantages of skcipher include: - A much less confusing name, since none of these algorithm types have ever actually been for raw block ciphers, but rather for all length-preserving encryption modes including block cipher modes of operation, stream ciphers, and other length-preserving modes. - It unified blkcipher and ablkcipher into a single algorithm type which supports both synchronous and asynchronous implementations. Note, blkcipher already operated only on scatterlists, so the fact that skcipher does too isn't a regression in functionality. - Better type safety by using struct skcipher_alg, struct crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc. - It sometimes simplifies the implementations of algorithms. Also, the blkcipher API was no longer being tested. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: user - fix memory leak in crypto_reportstat

2019-10-10T12:42:45+00:00

In crypto_reportstat, a new skb is created by nlmsg_new(). This skb is leaked if crypto_reportstat_alg() fails. Required release for skb is added. Fixes: cac5818c25d0 ("crypto: user - Implement a generic crypto statistics") Cc: Signed-off-by: Navid Emamdoost Signed-off-by: Herbert Xu

crypto: user - make NETLINK_CRYPTO work inside netns

2019-07-26T12:08:02+00:00

Currently, NETLINK_CRYPTO works only in the init network namespace. It doesn't make much sense to cut it out of the other network namespaces, so do the minor plumbing work necessary to make it work in any network namespace. Code inspired by net/core/sock_diag.c. Tested using kcapi-dgst from libkcapi [1]: Before: # unshare -n kcapi-dgst -c sha256 Signed-off-by: Herbert Xu

crypto: stat - remove unused mutex

2019-01-18T10:43:43+00:00

crypto_cfg_mutex in crypto_user_stat.c is unused. Remove it. Cc: Corentin Labbe Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: user - forward declare crypto_nlsk

2019-01-18T10:43:43+00:00

Move the declaration of crypto_nlsk into internal/cryptouser.h. This fixes the following sparse warning: crypto/crypto_user_base.c:41:13: warning: symbol 'crypto_nlsk' was not declared. Should it be static? Cc: Corentin Labbe Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: user - remove unused dump functions

2018-12-23T03:52:44+00:00

This patch removes unused dump functions for crypto_user_stats. There are remains of the copy/paste of crypto_user_base to crypto_user_stat and I forgot to remove them. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: user - rename err_cnt parameter

2018-12-07T06:15:00+00:00

Since now all crypto stats are on their own structures, it is now useless to have the algorithm name in the err_cnt member. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: user - Split stats in multiple structures

2018-12-07T06:15:00+00:00

Like for userspace, this patch splits stats into multiple structures, one for each algorithm class. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: user - remove intermediate variable

2018-12-07T06:15:00+00:00

The use of the v64 intermediate variable is useless, and removing it bring to much readable code. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: user - Fix invalid stat reporting

2018-12-07T06:15:00+00:00

Some error count use the wrong name for getting this data. But this had not caused any reporting problem, since all error count are shared in the same union. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu
