this is critical so all the tests will be contained in the same
directory, and one can just 'cp -a tests/ &lt;any-location&gt;/' and
run glusterfs tests.

only 'glfsxmp.c' was an exception as it was just copying the
file from api example directory. Now moved it to tests.

Problem:
Just setting the path to the CRL directory in socket_init() wasn't working.

Solution:
Need to use special API to retrieve and set X509_VERIFY_PARAM and set
the CRL checking flags explicitly.
Also, setting the CRL checking flags is a big pain, since the connection
is declared as failed if any CRL isn't found in the designated file or
directory. A comment has been added to the code appropriately.

<title>fuse: add --lru-limit option</title>

<id>d49b41e817d592c1904b6f01716df6546dad3ebe</id>
<content type='text'>
The inode LRU mechanism is moot in fuse xlator (ie. there is no
limit for the LRU list), as fuse inodes are referenced from
kernel context, and thus they can only be dropped on request of
the kernel. This might results in a high number of passive
inodes which are useless for the glusterfs client, causing a
significant memory overhead.

This change tries to remedy this by extending the LRU semantics
and allowing to set a finite limit on the fuse inode LRU.

A brief history of problem:

When gluster's inode table was designed, fuse didn't have any
'invalidate' method, which means, userspace application could
never ask kernel to send a 'forget()' fop, instead had to wait
for kernel to send it based on kernel's parameters. Inode table
remembers the number of times kernel has cached the inode based
on the 'nlookup' parameter. And 'nlookup' field is not used by
no other entry points (like server-protocol, gfapi etc).

Hence the inode_table of fuse module always has to have lru-limit
as '0', which means no limit. GlusterFS always had to keep all
inodes in memory as kernel would have had a reference to it.
Again, the reason for this is, kernel's glusterfs inode reference
was pointer of 'inode_t' structure in glusterfs. As it is a
pointer, we could never free it (to prevent segfault, or memory
corruption).

Solution:

In the inode table, handle the prune case of inodes with 'nlookup'
differently, and call a 'invalidator' method, which in this case is
fuse_invalidate(), and it sends the request to kernel for getting
the forget request.

When the kernel sends the forget, it means, it has dropped all
the reference to the inode, and it will send the forget with the
'nlookup' parameter too. We just need to make sure to reduce the
'nlookup' value we have when we get forget. That automatically
cause the relevant prune to happen.

Upcall notifications are received from server via epoll
and same thread is used to forward these notifications
to the application. This may lead to deadlock and hang
in the following scenario.

Consider if as part of handling these callbacks,
application has to do some operations which involve
sending I/Os to gfapi stack which inturn have to wait for
epoll threads to receive repsonse. Thus this may lead to
deadlock if all the epoll threads are waiting to complete
these callback notifications.

To address it, instead of using epoll thread itself,
make use of synctask to send those notificaitons to the
application.

When the glusterfs server recalls the lease, it expects
client to flush data and unlock the lease. If not it sets
a timer (starting from the time it sends RECALL request) and post
timeout, it revokes it.

Here we could have a race where in client did send UNLK
lease request but because of network delay it may have reached
after server revokes it. To handle such situations, treat
such requests as noop and return sucesss.

Based on the proposal to remove few features as they are not

build.

[1] https://lists.gluster.org/pipermail/gluster-users/2018-July/034400.html

This patch aims at clearing the translator from build and tests.
A followup is needed to remove the code from repository.
