[Bug 283965] nfs: page fault during nfsrpc_readdir

--- Comment #1 from Alan Somers  ---
I've determined that the cause of the failure in nfscl_invalidfname is because
my test fuse file system includes the NUL character in its readdir entries. 
That is, it replies something like this:

ents[0].d_namlen = 3;
ents[0].d_name = "..";
ents[1].d_namlen = 2;
ents[1].d_name = ".";

I can and will fix that in the tests.  But I can't guarantee that other fuse
file systems won't do the same.  Even if I have fusefs sanitize these strings
in-kernel, other file systems might do the same.  For example, I see that ext2
trusts the on-disk data, and copies it into a dirent without sanitizing it.  So
NFS must be able to handle that.

Fix handling of a nul in a file name received from an NFS server

I think this patch should fix the crash.

Hopefully Alan can test it?

Of course, CURRENT and 14 STABLE, but give me some days, please, I have some

Here in 2025 and I see no way to reproduce this with 15.0-CURRENT.

I am thinking close this as something we may never ever see again.

Here we are in 2025 and I see no easy way to reproduce this or even
to look at it. Given that 32-bit i386 type platform is hardly tier2
these days I am going to close this as not easy to reproduce.
