3Date: Wed, 31 Dec 2014 12:41:03 -0800
4Subject: [PATCH] Complain if an inc-recursive path is not right for its dir.
5 This ensures that a malicious sender can't use a just-sent symlink as a
6 trasnfer path.
7
8Upstream-Status: BackPort
9
10Fix the CVE-2014-9512, rsync 3.1.1 allows remote attackers to write to arbitrary
11files via a symlink attack on a file in the synchronization path.
12
13BackPort and fix this patch to make it able to apply to source code
