From: Li Qiang <liqiang...@360.cn>
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
uint64_t
9pfs: fix integer overflow issue in xattr read/write
