Subject: [Qemu-devel] [PATCH v3 0/3] 9pfs: fix xattr related issues
Date: Thu, 13 Oct 2016 03:09:40 -0700

From: Li Qiang <address@hidden>

The current xattr implementation in 9pfs has several issues.

-The 'copied_len' in V9fsXattr is used both for accounting bytes and to tag the 
xattr fid.
-The 'len/copied_len' field in V9fsXattr has a wrong type.
-The read/write dispatch function of xattr uses unsafe computations.

This patchset solves these issues.

Li Qiang (3):
  9pfs: add xattrwalk_fid field in V9fsXattr struct
  9pfs: convert 'len/copied_len' field in V9fsXattr to the type of
  9pfs: fix integer overflow issue in xattr read/write
