This is a note to let you know that I've just added the patch titled crypto: fix test vector for rsa to the 4.3-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-fix-test-vector-for-rsa.patch and it can be found in the queue-4.3 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@vger.kernel.org> know about it. From tadeusz.struk@intel.com Sun Feb 14 12:56:09 2016 From: Tadeusz Struk <tadeusz.struk@intel.com> Date: Wed, 13 Jan 2016 20:57:40 -0800 Subject: crypto: fix test vector for rsa To: Greg KH <gregkh@linuxfoundation.org> Cc: stable@vger.kernel.org, Herbert Xu <herbert@gondor.apana.org.au>, Linux Crypto Mailing List <linux-crypto@vger.kernel.org>, Linux Kernel Developers List <linux-kernel@vger.kernel.org>, David Howells <dhowells@redhat.com> Message-ID: <56972AC4.4010501@intel.com> From: Tadeusz Struk <tadeusz.struk@intel.com> After the fix to the asn1_decoder in commit: 0d62e9dd "ASN.1: Fix non-match detection failure on data overrun" the rsa algorithm is failing to register in 4.3 stable kernels with error: "alg: rsa: test failed on vector 4, err=-74" This happens because the asn1 definition for the rsa key that has been added in 4.2 defined all 3 components of the key as non-optional, as the asn1_decoder before the fix was working fine for both the private and public keys. This patch adds the missing (fake) component to one key vector to allow the algorithm to successfully register and be used with a valid private keys later. This is only to make the asn1_decoder successfully parse the key and the fake component is never used in the test as the vector is marked as public key. This patch applies only to 4.3 kernels as the 4.2 version of asn1_decoder works fine with the asn1 definition. 4.4 is also ok because the akcipher interface has been changed, and the set_key function has been split into set_public_key and set_priv_key and there are two separate asn1 definitions for the two key formats with all the required components correctly defined (commit 22287b0).
