Fix refcnt on shared UDP DRC
Every request as well as the xprt will place a ref on TCP DRC. The
ref is released when a request is finished as well as when the xprt
is removed. For UDP DRC, we only place a ref for every request. The UDP
xprt doesn't place a ref but does …
[View More]unref when it is removed leading to
"refcnt will underrun" log messages.
We could place a ref on UDP DRC for the xprt or we could avoid unref
on UDP xprt removal. Since UDP DRC is shared and never freed, its ref
counting is not needed. This patch removes ref counting of UDP DRC.

ganesha V2.7.6 wil cause Linux (kernel 3.2) nfs4xdr overflow
by fanzi2009＠hotmail.com
Hi experts,
I create VFS export in ganesha server. My client is ubuntu-12.04 and its kernel is 3.2.0. I tried to read a file in the client, such as
root@vagrant:~# cat /mnt/vfs/1.txt
cat: /mnt/vfs/1.txt: Input/output error
Below is the kernel log. It seems that print_overflow_msg() is called.

It seems only happen on Linux kernel 3.x rather than 4.x. I debug the issue, I found the issue is in the xdr_open_delegation4(). When the delegation_type is OPEN_DELEGATE_NONE_EXT, the problem happened. If it is OPEN_DELEGATE_NONE, it the problem is gone. I don't know what's the difference between them. Is this a ganesha bug or old Linux kernel bug?
Thanks,
Marvin
