Hi,
I am facing problem with reconnect_path failing with EACCES when doing
lookup_one_len. I have 2 users goind to same directory, one with uid=0
and another with uid=xxx. Sometime for uid=0 request, nfsd is still is using
uid=xxx (as it was used previously), as uid=xxx doesn't have any permissions
on the directory.
Should this probably do nfsd_setuser_and_check_port before
the below code in nfsd_set_fh_dentry()? As it carries older
fsuid and fsgid, can it create issues. This always happens
with disconnected dentries.
if (exp->ex_flags & NFSEXP_NOSUBTREECHECK) {
/* Elevate privileges so that the lack of 'r' or 'x'
* permission on some parent directory will
* not stop exportfs_decode_fh from being able
* to reconnect a directory into the dentry cache.
* The same problem can affect "SUBTREECHECK" exports,
* but as nfsd_acceptable depends on correct
* access control settings being in effect, we cannot
* fix that case easily.
Thanks,
Rajesh
