While attempting to build a (pre-)5.0 of glusterfs on Ubuntu
bionic and cosmic, it became apparent that there are some gremlins
hiding in the combination of the xlator export-symbols, the newish
addition of -Wl,--no-undefined, and the new switch to libuuid from
the old contrib/uuid.
Note: even though Fedora 28 (and later) and Ubuntu bionic (and
later) have the same nominal version of libtool, the Fedora version
appears to do a better job of recursing through dependencies to
determine the libraries to link with.
Examination of the build logs showed that despite appearing to work
on Fedora, not all xlators and shared libs were linked with -Wl,
--no-undefined, and -luuid. And in the case of the gnfs xlator, it
was not only not linked with -Wl,--no-undefined but alsos not linked
with -lgfxdr and -lgfrpc.
Added GF_XLATOR_LDFLAGS, similar to GF_XLATOR_DEFAULT_LDFLAGS.
GF_XLATOR_DEFAULT_LDFLAGS is for xlators that export/expose the
default or common set of symbols. GF_XLATOR_LDFLAGS is for those
remaining xlators that export/expose non-default symbols, e.g. dht
and glupy. This removes the need in the future to add things like
$(UUID_LIBS) to every xlator's Makefile.am. Just add it to
GF_XLATOR_LDFLAGS and GF_XLATOR_DEFAULT_LDFLAGS in configure.ac
and you're done.
This patch was tested on Fedora 28 (build, rpmbuild), Fedora
Rawhide/30 (rpmbuild), RHEL8 (rpmbuild), CentOS7 (rpmbuild), Fedora
koji --scratch build for f30/rawhide, and a Launchpad build for
Ubuntu cosmic/18.10.

current implementation of alloca can cause issues when strings larger
than the allocated buffer is passed to the xdr. Hence it makes sense
to allow XDR decode functions to deal with memory allocations, which
we can free later.

This will prevent any arbitrary file creation through glusterfs
by modifying the client bits.
Also check for the similar flaw inside posix too, so we prevent any
changes in layers in-between.

Move to GF_MALLOC() instead of GF_CALLOC() when possible
It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.
In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.
1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.
Only compile-tested!
.. and allocate memory as much as needed.

appropriately.

Introduce a `./configure --enable-asan` to build with
`-fsanitize=address -fno-omit-frame-pointer` options. This uses the
libasan.so shared library, so that needs to be available.
While running builds with the ASAN options, several linker issues
surfaced and these have been addressed with this change as well.
Building with --enable-asan has been tested on Fedora 28.

Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h
file that on occasion gets included instead of the libglusterfs file.
When this happens, 'struct event_pool' will not be defined and building
will fail with errors like:
autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool'
int thread_count = pool->eventthreadcount;
~~~~^
autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool'
struct event_pool *pool = ctx->event_pool;
^
This problem is caused by 'pkg-config --cflags uuid' that adds
/usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred
so that the contrib/uuid/ directory can be removed.
By renaming event.h to gf-event.h there is no conflict between the
different event.h files anymore and compiling on FreeBSD works without
issues.

This change explicitly adds 'ssl-allow' options to the server xlator's
options table so that glusterd2 can see it as a settable option. This
change also marks 'auth.allow' and 'auth.reject' options as a settable.
Glusterd2 doesn't maintain a separate volume options table. Glusterd2
dynamically loads shared objects of xlators to read their option table
and other information. Glusterd2 reads 'xlator_api_t' if available. If
that's not available, it falls back to reading just the options table
directly.
In glusterd2, volume set operations are performed by users on keys of
the format <xlator>.<option-name>. Glusterd2 uses xlator name set in
'xlator_api_t.identifier'. If that's not present it will use the shared
object's file name as xlator name. Hence, it is important for
'xlator_api_t.identifier' to be set properly, and in this case, the
proper value is "server". This name shall be used by users as prefix
while setting volume options implemented in server xlator. The name will
also be used in volfile.
A user in glusterd2 can authorize a client over TLS as follows:
$ glustercli volume set <volname> server.ssl-allow <client1-CN>[,<clientN-CN>]

client_submit_vec_request() which is used by WRITEV, and PUT
and client_submit_request() used by the rest of the fops have
almost similar code. However, there have been some more checks
- such as whether setvolume was successful or not, and one more
that is send-gid-specific - that have been missed out in the vectored
version of the function.
This patch fixes this code duplication.

The state management of "connected" in rpc is ad-hoc as far as the
responsibility goes. Note that there is nothing wrong with
functionality itself. rpc layer manages this state in disconnect
codepath and has exposed an api to manage this one from
consumers. Note that rpc layer never sets "connected" to true by
itself, which forces the consumers to use this api to get a working
rpc connection. The situation is best captured from a comment in code
from Jeff Darcy in glusterfsd/src/gf-attach.c:
-/*
- * In a sane world, the generic RPC layer would be capable of tracking
- * connection status by itself, with no help from us. It might invoke our
- * callback if we had registered one, but only to provide information. Sadly,
- * we don't live in that world. Instead, the callback *must* exist and *must*
- * call rpc_clnt_{set,unset}_connected, because that's the only way those
- * fields get set (with RPC both above and below us on the stack). If we don't
- * do that, then rpc_clnt_submit doesn't think we're connected even when we
- * are. It calls the socket code to reconnect, but the socket code tracks this
- * stuff in a sane way so it knows we're connected and returns EINPROGRESS.
- * Then we're stuck, connected but unable to use the connection. To make it
- * work, we define and register this trivial callback.
- */
Also, consumers of rpc know about state of connection only through the
notifications sent by rpc-clnt. So, consumers don't have any extra
information to manage the state and hence letting them manage the
state is counter intuitive. This patch cleans that up and instead
moves the responsibility of state management of rpc layer into
itself.

An earlier commit set conf->connected just after rpc layer sends
RPC_CLNT_CONNECT event. However, success of socket level connection
connection doesn't indicate brick stack is ready to receive fops, as
an handshake has to be done b/w client and server after
RPC_CLNT_CONNECT event. Any fop sent to brick in the window between,
* protocol/client receiving RPC_CLNT_CONNECT event
* protocol/client receiving a successful setvolume response
can end up accessing an uninitialized brick stack. So, set
conf->connected only after a successful SETVOLUME.

Earlier glusterfs never had an assumption someone would start it with
right arguments, and brick processes would be spawned by a management
layer. It just assume the role based on the volfile. Other than
volfile, no other arguments should be technically mandatory for
working of glusterfs. With this patch, that assumption holds true.
Updates: github issue # 352
A note on why this particular issue for this basic sanity?
As per the design of thin-arbiter/tie-breaker, it can be started
independently on any machine, without need of glusterd. So, similar
to 'glusterd', we should be able to spawn a process with any translator
without options/volume id etc.

lookup, create, mknod etc) and fops that remove a dentry (like rename,
unlink, rmdir etc) due to which stale dentries are left out in inode
table even though the dentry doesn't exist on backend. For eg.,
consider a lookup (parent/bname) and unlink (parent/bname) racing in
the following order:
* lookup hits storage/posix and finds that dentry exists
* unlink removes the dentry on storage/posix
* unlink reaches protocol/server where the dentry (parent/bname) is
unlinked from the inode
* lookup reaches protocol/server and creates a dentry (parent/bname)
on the inode
Now we've a stale dentry (parent/bname) associated with the inode in
itable. This situation is bad for fops like link, create etc which
invoke resolver with type RESOLVE_NOT. These fops fail with EEXIST
even though there is no such dentry on backend fs. This issue can be
solved in two ways:
* Enable "dentry fop serializer" xlator [1].
# gluster volume set features.sdfs on
* Make sure resolver does a lookup on backend when it finds a dentry
in itable and validates the state of itable.
- If a dentry is not found, unlink those stale dentries from itable
and continue with fop
- If dentry is found, fail the fop with EEXIST
This patch implements second solution as sdfs is not enabled by
default in brick xlator stack. Once sdfs is enabled by default, this
patch can be reverted.

When this option is enabled, we will check for a matching
username and password, if not found then the connection will
be rejected. This also does a checksum validation of volfile
The option is invalid when SSL/TLS is in use, at which point
the SSL/TLS certificate user name is used to validate and
hence authorize the right user. This expects TLS allow rules
to be setup correctly rather than the default *.
This option is not settable, as a result this cannot be enabled
for volumes using the CLI. This is used with the shared storage
volume, to restrict access to the same in non-SSL/TLS environments
to the gluster peers only.
Tested:
./tests/bugs/protocol/bug-1321578.t
./tests/features/ssl-authz.t
- Ran tests on volumes with and without strict auth
checking (as brick vol file needed to be edited to test,
or rather to enable the option)
- Ran tests on volumes to ensure existing mounts are
disconnected when we enable strict checking

Problem: glusterd2 build is failed due to undefined symbol
(xlator_mem_cleanup , glusterfsd_ctx) in server.so
Solution: To resolve the same done below two changes
1) Move xlator_mem_cleanup code from glusterfsd-mgmt.c
to xlator.c to be part of libglusterfs.so
2) replace glusterfsd_ctx to this->ctx because symbol
glusterfsd_ctx is not part of server.so

Problem: Sometimes brick process is getting crashed at the time
of stop brick while brick mux is enabled.
Solution: Brick process was getting crashed because of rpc connection
was not cleaning properly while brick mux is enabled.In this patch
after sending GF_EVENT_CLEANUP notification to xlator(server)
waits for all rpc client connection destroy for specific xlator.Once rpc
connections are destroyed in server_rpc_notify for all associated client
for that brick then call xlator_mem_cleanup for for brick xlator as well as
all child xlators.To avoid races at the time of cleanup introduce
two new flags at each xlator cleanup_starting, call_cleanup.

Problem:
The values for inode/fd was populated from the ctx received
from the server xlator.
Without brickmux, every brick from a volume belonged to a
single brick from the volume.
So searching the server and populating it worked.
With brickmux, a number of bricks can be confined to a single
process. These bricks can be from different volumes too (if
we use the max-bricks-per-process option).
If they are from different volumes, using the server xlator
to populate causes problem.
Fix:
Use the brick to validate and populate the inode/fd status.

In a mixed mode cluster involving 4.0 and older 3.x bricks, if
clients are newer, then the iatt encoded in the dictionary can be
of the older iatt format, which a newer client will map incorrectly
to the newer structure.
This causes failures in FOPs that depend on this iatt for some
functionality (seen in mkdir operations failing as EIO, when DHT
hits its internal setxattr call).
The fix provided is to convert the iatt in the dict, based on which
RPC version is used to communicate with the server.
IOW, this is the reverse of change in commit "b966c7790e"
Tested using a mixed mode cluster (i.e bricks in 3.12 and 4.0 versions)
and a mixed set of clients, 3.12 and 4.0 clients.
There is no regression test provided, as this needs a mixed mode cluster
to test and validate.

Added iatt conversion to an older format, when dealing with
older RPC versions. This enables iatt structure conformance
when dealing with older clients.
This helps fix rolling upgrade from 3.x versions to 4.0 version
of gluster by sending the right iatt in the dictionary when DHT
requests the same.

There was an issue when some accesses to saved_fds list were
protected by the wrong mutex (lock instead of fd_lock).
Additionally, the retrieval of fdctx from fd's context and any
checks done on it have also been protected by fd_lock to avoid
fdctx to become outdated just after retrieving it.

We have the following undefined symbol error from protocol/server.so:
glusterfs_mgmt_pmap_signout
glusterfs_autoscale_threads
See https://review.gluster.org/19225 (bz#1532238)
and https://review.gluster.org/19657 (bz#1550895)
(why are there two different bzs for the same bug?)
IMO this is a cleaner solution. I.e. moving the above two functions
to libgfrpc (.../rpc/rpc-lib/...)
I would also, for (foolish) consistency sake, like to see
glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as
well.
This works on f28/rawhide, with its new, more restrictive run-time
link semantics. The smoke and regression tests on earlier fedora and
centos will confirm that it works on those platforms too.

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.
With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

With https://review.gluster.org/#/c/12363/ being merged, we no longer
send client's lk-version to server side and the corresponding check on
server is also removed. But when clients are upgraded prior to servers,
the check for lk-version at server side fails and is reported back to
clients resulting in disconnection.
Since we don't have lock-recovery (lk-version and grace-timeout) logic
anymore in code base our best bet would be to add client's default
lk-version i.e, 1, into the dictionary just to make server side check
pass and continue with remaining SETVOLUME operations.
