Message-Id: <1320790365-29152-1-git-send-email-nbowler@elliptictech.com> Date: Tue, 8 Nov 2011 17:12:43 -0500 From: Nick Bowler <nbowler@...iptictech.com> To: netdev@...r.kernel.org, linux-kernel@...r.kernel.org Cc: "David S. Miller" <davem@...emloft.net> Subject: [PATCH 0/2] AH fixes for asynchronous hash algorithms. Here are two fixes for AH when using an asynchronous hmac driver. Both are -stable candidates as these problems appear to have been present since AH was converted to use ahash way back in 2.6.33. These code paths are not exercised when using the default software hash implementations which do not use the ahash callbacks, but the issues can be reproduced by using cryptd to create an asynchronous hash algorithm for testing. This driver could probably do with some cleanups to reduce the code duplication (and thus test coverage) between the asynchronous callbacks and synchronous code paths, which should help avoid these kind of problems in the future. These code paths apparently do not see a lot of testing. But that's for a later patch series. Nick Bowler (2): ah: Correctly pass error codes in ahash output callback. ah: Read nexthdr value before overwriting it in ahash input callback. net/ipv4/ah4.c | 6 ++---- net/ipv6/ah6.c | 6 ++---- 2 files changed, 4 insertions(+), 8 deletions(-) -- 1.7.3.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
