crypto: blkcipher_get_spot() handling of buffer at end of page

2007-09-26T17:54:41Z

This corresponds to upstream changesets e4630f9fd8cdc14eb1caa08dafe649eb5ae09985 and 32528d0fbda1093eeeaa7d0a2c498bbb5154099d. [CRYPTO] blkcipher: Fix handling of kmalloc page straddling The function blkcipher_get_spot tries to return a buffer of the specified length that does not straddle a page. It has an off-by-one bug so it may advance a page unnecessarily. What's worse, one of its callers doesn't provide a buffer that's sufficiently long for this operation. This patch fixes both problems. Thanks to Bob Gilligan for diagnosing this problem and providing a fix. Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

[CRYPTO] cryptd: Fix problem with cryptd and the freezer

2007-05-31T08:10:22Z

Make sure that cryptd is marked as nonfreezable and does not hold up the freezer. Signed-off-by: Rafael J. Wysocki Signed-off-by: Herbert Xu

[CRYPTO] api: Read module pointer before freeing algorithm

2007-05-19T04:51:00Z

The function crypto_mod_put first frees the algorithm and then drops the reference to its module. Unfortunately we read the module pointer which after freeing the algorithm and that pointer sits inside the object that we just freed. So this patch reads the module pointer out before we free the object. Thanks to Luca Tettamanti for reporting this. Signed-off-by: Herbert Xu

[CRYPTO] tcrypt: Add missing error check

2007-05-18T06:25:19Z

The return value of crypto_hash_final isn't checked in test_hash_cycles. This patch corrects this. Thanks to Eric Sesterhenn for reporting this. Signed-off-by: Herbert Xu

[CRYPTO] cryptomgr: Fix use after free

2007-05-09T03:04:39Z

By the time kthread_run returns the param may have already been freed so writing the returned thread_struct pointer to param is wrong. In fact, we don't need it in param anyway so this patch simply puts it on the stack. Signed-off-by: Herbert Xu

[CRYPTO] cryptd: Add software async crypto daemon

2007-05-02T04:38:32Z

This patch adds the cryptd module which is a template that takes a synchronous software crypto algorithm and converts it to an asynchronous one by executing it in a kernel thread. Signed-off-by: Herbert Xu

[CRYPTO] api: Do not remove users unless new algorithm matches

2007-05-02T04:38:32Z

As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu

[CRYPTO] cryptomgr: Fix parsing of nested templates

2007-05-02T04:38:31Z

This patch allows the use of nested templates by allowing the use of brackets inside a template parameter. Signed-off-by: Herbert Xu

[CRYPTO] api: Add async blkcipher type

2007-05-02T04:38:31Z

This patch adds the mid-level interface for asynchronous block ciphers. It also includes a generic queueing mechanism that can be used by other asynchronous crypto operations in future. Signed-off-by: Herbert Xu
