Subject: Use lstat rather than stat in gssd_find_existing_krb5_ccache
X-Git-Tag: nfs-utils-1-1-0-rc1~70
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=a4fe85a8e98655aa9be534258074312446d337ab;p=nfs-utils.git

Use lstat rather than stat in gssd_find_existing_krb5_ccache

As this is a file in /tmp, a symlink could take us anywhere...
If it was a NFS filesystem with a dead server, we could block for a long time..
