Avi Kivity 69bbd9c7b9 nfs: fix nfs4d readlink truncated packet ... XDR requires 4-byte alignment; nfs4d READLINK reply writes out the padding, but truncates the packet to the padding-less size. Fix by taking the padding into consideration when truncating the packet. Symptoms: # ll /mnt/ ls: cannot read symbolic link /mnt/test: Input/output error total 4 -rw-r--r--. 1 root root 0 Jun 14 01:21 123456 lrwxrwxrwx. 1 root root 6 Jul 2 03:33 test drwxr-xr-x. 1 root root 0 Jul 2 23:50 tmp drwxr-xr-x. 1 root root 60 Jul 2 23:44 tree Signed-off-by: Avi Kivity <avi@cloudius-systems.com> Fixes: 476a7b1f4b (nfsd4: don't treat readlink like a zero-copy operation) Reviewed-by: Kinglong Mee <kinglongmee@gmail.com> Signed-off-by: J.
