From: Lorenzo Colitti Date: Wed, 10 May 2017 14:54:04 +0000 (+0900) Subject: ANDROID: net: xfrm: make PF_KEY SHA256 use RFC-compliant truncation. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=350c0df01370ac0de4a4bb30b5d4f33625114844;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ANDROID: net: xfrm: make PF_KEY SHA256 use RFC-compliant truncation. When using the PF_KEY interface, SHA-256 hashes are hardcoded to use 96-bit truncation. This is a violation of RFC4868, which specifies 128-bit truncation, but will not be fixed upstream due to backwards compatibility concerns and because the PF_KEY interface is deprecated in favour of netlink XFRM (which allows the app to specify an arbitrary truncation length). Change the hardcoded truncation length from 96 to 128 so that PF_KEY apps such as racoon will work with standards-compliant VPN servers.
