[OpenAFS] Return of the getcwd bug?

[Neil Brown]

Hi,

Today I've been bitten twice by what appears to be the getcwd bug. I've 
not had this problem in a long time. I thought that had been resolved? Is 
anyone else seeing this?

This was on both a 1.8.2 and a 1.8.0 client. My home volume is on a 1.6.23 
server.

Some details below.

Cheers,

Neil

(~)> uname -srv

You should see the cwd here - No such file or directory

openafs-client-1.8.0-1.el7.x86_64
(tmp)> fs version
openafs 1.8.0

On the 1.8.2 machine:
(~)> uname -srv
Linux 3.10.0-862.14.4.el7.x86_64 #1 SMP Tue Sep 25 14:32:52 CDT 2018
(~)> pwd
/afs/inf.ed.ac.uk/user/n/neilb
(~)> getcwd 
You should see the cwd here - No such file or directory
(~)> cd tmp
(tmp)> getcwd 
You should see the cwd here - /afs/inf.ed.ac.uk/user/n/neilb/tmp
(tmp)> rpm -q openafs
openafs-1.8.2-1.el7.x86_64
(tmp)> fs version
openafs 1.8.2

My "getcwd" script basically does
   perl -e 'use Cwd; print getcwd()'

And the server with my home volume:

: uname -srv
Linux 3.10.0-862.14.4.el7.x86_64 #1 SMP Tue Sep 25 14:32:52 CDT 2018
: bos version
openafs 1.6.23
: rpm -q openafs
openafs-1.6.23-1.el7.x86_64
