crypto: api - Only abort operations on fatal signal

2015-11-12T13:09:02Z

commit 3fc89adb9fa4beff31374a4bf50b3d099d88ae83 upstream. Currently a number of Crypto API operations may fail when a signal occurs. This causes nasty problems as the caller of those operations are often not in a good position to restart the operation. In fact there is currently no need for those operations to be interrupted by user signals at all. All we need is for them to be killable. This patch replaces the relevant calls of signal_pending with fatal_signal_pending, and wait_for_completion_interruptible with wait_for_completion_killable, respectively.

crypto: user - fix info leaks in report API

2013-02-19T12:27:03Z

Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all. Signed-off-by: Mathias Krause Cc: Steffen Klassert Signed-off-by: Herbert Xu

crypto: Stop using NLA_PUT*().

2012-04-02T08:33:42Z

These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller

crypto: user - Fix lookup of algorithms with IV generator

2012-03-29T11:52:47Z

We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg(). Signed-off-by: Steffen Klassert Signed-off-by: Herbert Xu

crypto: algapi - Fix build problem with NET disabled

The report functions use NLA_PUT so we need to ensure that NET is enabled. Reported-by: Luis Henriques Signed-off-by: Herbert Xu

crypto: skcipher - avoid NULL dereference

2010-06-23T10:01:45Z

Stanse found a potential NULL dereference in ablkcipher_next_slow. Even though kmalloc fails, its retval is dereferenced later. Return from that function properly earlier. Signed-off-by: Jiri Slaby Acked-by: David S. Miller Signed-off-by: Herbert Xu
