File 0204-9pfs-fix-memory-leak-in-v9fs_xattrc.patch of Package qemu.15027
From fa76b5e60cf27e9285dcf3f807f591a1f86ceea5 Mon Sep 17 00:00:00 2001 From: Li Qiang <liqiang6-s@360.cn> Date: Mon, 17 Oct 2016 14:13:58 +0200 Subject: [PATCH] 9pfs: fix memory leak in v9fs_xattrcreate The 'fs.xattr.value' field in V9fsFidState object doesn't consider the situation that this field has been allocated previously. Every time, it will be allocated directly. This leads to a host memory leak issue if the client sends another Txattrcreate message with the same fid number before the fid from the previous time got clunked.
