When overwriting an existing file with O_TRUNC, the 'atime' was set to
0, meaning the Epoch (01-Jan-1970 UTC). However, the 'mtime' gets
updated correcty.
In case 'atime' or 'mtime' is not passed in the 'struct iatt', the time
values passed to the systemcall are taken from the current values are
returned by lstat().

Backport of http://review.gluster.org/#/c/15923/
Issue:
=====
In certain cases, there was no unwind of read
from read-ahead xlator, thus resulting in hang.
RCA:
====
In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead
of STACK_WIND(). One such case is when inode_ctx for that file
is not present (can happen if readdirp was called, and populates
md-cache and serves all the lookups from cache).
Consider the following graph:
...
io-cache (parent)
|
readdir-ahead
|
read-ahead
...
Below is the code snippet of ioc_readv calling STACK_WIND_TAIL:
ioc_readv()
{
...
if (!inode_ctx)
STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this),
FIRST_CHILD (frame->this)->fops->readv, fd,
size, offset, flags, xdata);
/* Ideally, this stack_wind should wind to readdir-ahead:readv()
but it winds to read-ahead:readv(). See below for
explaination.
*/
...
}
STACK_WIND_TAIL (frame, obj, fn, ...)
{
frame->this = obj;
/* for the above mentioned graph, frame->this will be readdir-ahead
* frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which
* is as expected
*/
...
THIS = obj;
/* THIS will be read-ahead instead of readdir-ahead!, as obj expands
* to "FIRST_CHILD (frame->this)" and frame->this was pointing
* to readdir-ahead in the previous statement.
*/
...
fn (frame, obj, params);
/* fn will call read-ahead:readv() instead of readdir-ahead:readv()!
* as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and
* frame->this was pointing ro readdir-ahead in the first statement
*/
...
}
Thus, the readdir-ahead's readv() implementation will be skipped, and
ra_readv() will be called with frame->this = "readdir-ahead" and
this = "read-ahead". This can lead to corruption / hang / other problems.
But in this perticular case, when 'frame->this' and 'this' passed
to ra_readv() doesn't match, it causes ra_readv() to call ra_readv()
again!. Thus the logic of read-ahead readv() falls apart and leads to
hang.
Solution:
=========
Modify STACK_WIND_TAIL() as:
STACK_WIND_TAIL (frame, obj, fn, ...)
{
next_xl = obj /* resolve obj as the variables passed in obj macro
can be overwritten in the further instrucions */
next_xl_fn = fn /* resolve fn and store in a tmp variable, before
modifying any variables */
frame->this = next_xl;
...
THIS = next_xl;
...
next_xl_fn (frame, next_xl, params);
...
}

On a sharded volume when a brick is replaced while IO is going on, named
lookup on individual shards as part of read/write was failing with
ENOENT on the replaced brick, and as a result AFR initiated name heal in
lookup callback. But since pargfid was empty (which is what this patch
attempts to fix), the resolution of the shards by protocol/server used
to fail and the following pattern of logs was seen:

gfapi needs to provide a function towards applications to free memory
that it allocated. Depending on how the application is compiled/linked,
it could use a different memory allocator than Gluster itself. Therefore
it is not safe for gfapi to request applications to free memory with
'standard' free().
Examples for this are Gluster allocated structures with GF_CALLOC() when
memory accounting is enabled (the default). Some gfapi functions use
malloc() to allocate memory as a workaround, but the free() from the
jemalloc implementation should not be combined with the malloc() from
glibc.

cyclic order
Backport of: http://review.gluster.org/15080
When the bricks are brought offline and then online in cyclic
order while writes are in progress on a file, thanks to inode
refresh in write txns, AFR will mostly fail the write attempt
when the only good copy is offline. However, there is still a
remote possibility that the file will run into split-brain if
the brick that has the lone good copy goes offline *after* the
inode refresh but *before* the write txn completes (I call it
in-flight split-brain in the patch for ease of reference),
requiring intervention from admin to resolve the split-brain
before the IO can resume normally on the file. To get around this,
the patch does the following things:
i) retains the dirty xattrs on the file
ii) avoids marking the last of the good copies as bad (or accused)
in case it is the one to go down during the course of a write.
iii) fails that particular write with the appropriate errno.
This way, we still have one good copy left despite the split-brain situation
which when it is back online, will be chosen as source to do the heal.

As part of inode_table_destroy(), we first retire entries
in the lru list but the lru_size is not adjusted accordingly.
This may result in invalid memory reference in inode_table_prune
if the lru_size > lru_limit.

Problems: The maximum number of migratior threads created was static set
to "40". And the number of these threads get created in rebalance depends
on the number of cores user has. If the number of cores exceeds 40, a
crash or memory corruption can be seen.
Fix: Make the migratior thread pool dynamic.

socket_spawn.
Problem: Current approach to cleanup threads of socket_poller is not appropriate.
Solution: Enable detach flag at the time of thread creation in socket_spawn.
Fix: Write a new wrapper(gf_create_detach_thread) to create detachable thread
instead of store thread ids in a queue.
Test: Fix is verfied on gluster process, To test the patch followed below
procedure
Enable the client.ssl and server.ssl option on the volume
Start the volume and count anon segment in pmap output for glusterd process
pmap -x <glusterd-pid> | grep "\[ anon \]" | wc -l
Stop the volume and check again count of anon segment it should not increase.

One of the consumers of a page aligned buffer would be posix's
readv fop on O_DIRECT fds. Today the way it works is by getting
a page-aligned buffer through calloc, pread()ing into this buffer
and then copying its contents into a newly created iobuf's ptr.
This results in an extra memcpy() which can be avoided if we could
implement an api that would return an iobuf whose ptr is
page-aligned. That way the iobuf->ptr can be directly passed to
sys_pread() as a parameter by posix translator.

This is to prevent any unforeseen problems that might arise due to
writevs and readvs being wound with @flag parameter containing
O_TRUNC or O_APPEND especially wrt translators like sharding and ec
where O_TRUNC write or O_APPEND write on individual shards/fragments
is not the same as O_TRUNC write or O_APPEND write as expected by the
application.

If the application opens a file with O_DIRECT, the shards'
anon fds would also need to inherit the flag. Towards this,
shard xl would be passing the odirect flag in the @flags parameter
to the WRITEV fop. This will be used in anon fd resolution
and subsequent opening by posix xl.

__fd_unref() doesn't do any cleanup, so it cannot be called to release
fd references, specially if it's the last reference.
The code has been changed to avoid a call to this function.
In the previous version we always tried to keep the newest fd in the
ec_lock_t structure. However this is not necessary. We'll always keep
one reference to an open file on the same inode. It's irrelevant if
the reference is new or old.
The function __fd_unref() has also been removed from fd.h to avoid being
used in the future since it's useless as it's defined now.

We do not set the same flags to anonymous fd that posix uses to open
an anonymous fd in the backend. If there are any xlators which rely on
these flags for their operation they may not work well.
Add proper flags to anonymous fds at the time of their creation and
refer to them for subsequent operations.

Problem:
Afr does post-ops after write but the stat buffer it unwinds is at the
time of write, so if nfs client caches this, it will see different
ctime when it does stat on it after post-op is done. From NFS client's
perspective it thinks the file is changed. Tar which depends on this
to be correct keeps giving 'file changed as we read it' warning.
If Afr instead has to choose to unwind after post-op, eager-lock,
delayed-post-op will have to be disabled which will lead to bad
performance for all write usecases.
Fix:
Don't let client cache stat after write.

Problem:
Negative cache feature implementation in md-cache requires xattrs
returned by posix to be intercepted for every call that can possibly
return xattrs. This includes readdirp(). This is crucial to treat
missing keys in cache as a case of negative entry (returns ENODATA)
md-cache puts names of xattrs that it wants to cache in xdata and
passes it down to posix which returns the specified xattrs in the
callback. This is done in lookup() and readdirp(). Hence, a xattr
that is cached can be invalidated during readdirp_cbk too.
This is based on the assumption that readdirp() will always return
all xattrs that md-cache is interested in. However, this is not the
case when readdirp() call is served from readdir-ahead's cache.
readdir-ahead xlator will pre-fetch dentries during opendir_cbk
and readdirp. These internal readdirp() calls made by readdir-ahead
xlator does not set xdata in it's requests. Hence, no xattrs are
fetched and stored in it's internal cache.
This causes metadata loss in gluster-swift. md-cache returns ENODATA
during getxattr() call even though the xattr for that object exists on
the brick. On receiving ENODATA, gluster-swift will create new metadata
and do setxattr(). This results in loss of information stored in
existing xattr.
Fix:
During opendir, md-cache will communicate to readdir-ahead asking it
to store the names of xattrs it's interested in so that readdir-ahead
can fetch those in all subsequent internal readdirp() calls issued by
it. This stored names of xattrs is invalidated/updated on the next
real readdirp() call issued by application. This readdirp() call will
have xdata set correctly by md-cache xlator.

Problem:
when bind-insecure is 'off', all the clients bind to secure ports,
if incase all the secure ports exhaust the client will no more bind
to secure ports and tries gets a random port which is obviously insecure.
we have seen the client obtaining a port number in the range 49152-65535
which are actually reserved as part of glusterd's pmap_registry for bricks,
hence this will lead to port clashes between client and brick processes.
Solution:
If we can define different port ranges for clients incase where secure ports
exhaust, we can avoid the maximum port clashes with in gluster processes.
Still we are prone to have clashes with other non-gluster processes, but
the chances being very low, but that's a different story on its own, which
will be handled in upcoming patches.

Intro:
Currently glusterd maintain the portmap registry which contains ports that
are free to use between 49152 - 65535, this registry is initialized
once, and updated accordingly as an then when glusterd sees they are been
used.
Glusterd first checks for a port within the portmap registry and gets a FREE
port marked in it, then checks if that port is currently free using a connect()
function then passes it to brick process which have to bind on it.
Problem:
We see that there is a time gap between glusterd checking the port with
connect() and brick process actually binding on it. In this time gap it could
be so possible that any process would have occupied this port because of which
brick will fail to bind and exit.
Case 1:
To avoid the gluster client process occupying the port supplied by glusterd :
we have separated the client port map range with brick port map range more @
http://review.gluster.org/#/c/13998/
Case 2: (Handled by this patch)
To avoid the other foreign process occupying the port supplied by glusterd :
To handle above situation this patch implements a mechanism to return EADDRINUSE
error code to glusterd, upon which a new port is allocated and try to restart
the brick process with the newly allocated port.
Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to
handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit
code of the executed command (brick process). Hence as of now in such case,
we cannot know with what error the brick has failed to connect.
This patch also fix the runner_end() to perform some cleanup w.r.t
return values.

Recent changes done w.r.t handling of mkdir calls in posix translator
resulted in crashing the brick process from trash translator. This was
due to the changes made in posix translator to return EPERM for every
mkdir calls without 'gfid-req' set in dictionary. In order to avoid
gfid mismatches during directory creation from brick side trash
translator does not set 'gfid-req'. This patch is to have an exemption
for trash based on a special pid set for those mkdir calls originating
from trash translator and to reset it in callback.
This patch also includes a small optimization to the existing test case for trash feature.

by glusterfs clients like shd, quotad etc. In order to have this enum
capable of holding all other special PIDs including the one used by
trash translator, _gf_client_pid is being renamed to _gf_special_pid.

Backport of http://review.gluster.org/13448
commit c4d67a8338b42d6485f49999f310cbb9ed5359c5
It has become very difficult to identify the xlator which returned
negative op_ret. Being able to just change the log level and
visualize the stack is helpful in such cases.

Intro:
pid_t waitpid(pid_t pid, int *status, int options);
The waitpid() system call suspends execution of the calling process
until a child specified by pid argument has changed state.
Here the ret (pid) value is not equal to the exit status of the child process.
Check manpages for more info on this.
Problem:
In the current runner framework we always return the pid i.e ret value
of the waitpid, as said above it is not the exit value of the child process
Solution:
Extract the actual exit code/status in case if the child terminated normally,
that is, by calling exit(3) or _exit(2), or by returning from main()

In inode_table_destroy, we iterate through lru and active lists
to move the entries to purge list so that they can be destroyed
during inode_table_prune.
But if used "list_for_each_entry" or "list_for_each_entry_safe"
to iterate, we could end up accessing the entries which may have
got moved to different(purge) lists in the process and can result
in either infinite loop or crash. The safe approach seems to fetch
the first entry of the list in each iteration till it gets empty.

As a part of CHILD_MODIFIED event DHT forgets the current layout and
performs fresh lookup. However this is not required when a replica pair
goes offline as the xattrs can be read from other replica pairs. Hence
setting different event to handle replica pair going down.

When quota is enabled the quota enforcer tries to get the size of the
source directory by sending nameless lookup to quotad. But if the rename
is successful even on one subvol or the source layout has anomalies then
this nameless lookup in quotad tries to heal the directory which requires
a lock on as many subvols as it can. But src is already locked as part of
rename. For rename to proceed in brick it needs to complete a cluster-wide
lookup. But cluster-wide lookup in quotad is blocked on locks held by rename,
hence a deadlock. To avoid this quota sends an option in xdata which instructs
DHT not to heal.

When querying we will order the query result to get
the hotest or the coldest files in the queried list
so that these files are migrated first.
Now here we are giving priority to the write heat(time and counters),
as it requires complex queries to have a composite
ordering of write and read + it has it impact on performance.

Similar changes need to be done for dentry operations like create,
symlink, link, unlink, rmdir, rename. These will be addressed in
subsequent patches. This patch addresses only mkdir codepath.
This change breaks stripe tests, as on some striped subvols dht layout
xattrs are not set for some reason. This results in failure of
mkdir. Since striped volumes are always created with dht, some tests
associated with stripe also fail. So, I am making following tests
changes (since stripe is out of maintainance):
* modify ./tests/basic/rpc-coverage.t to not to use striped volumes
* mark all (2) tests in tests/bugs/stripe/ as bad tests

Most of this functionality's ideas are contributed
by Richard Wareing, in his patch:
https://bugzilla.redhat.com/show_bug.cgi?id=1221737#c1
VERY BIG thanks to him :-).
After starting porting/testing the patch above, I found a few things we can
improve in this patch based on the results we got in testing.
1) We are reading all the indices before we launch self-heals. In some customer
cases I worked on there were almost 5million files/directories that needed
heal. With such a big number self-heal daemon will be OOM killed if we go
this route. So I modified this to launch heals based on a queue length
limit.
2) We found that for directory hierarchies, multi-threaded self-heal
patch was not giving better results compared to single-threaded
self-heal because of the order problems. We improved index xlator to
give gfid type to make sure that all directories in the indices are
healed before the files that follow in that iteration of readdir
output(http://review.gluster.org/13553). In our testing this lead to
zero errors of self-heals as we were only doing self-heals in parallel
for files and not directories. I think we can further improve self-heal
speed for directories by doing name heals in parallel based on similar
techniques Richard's patch showed. I think the best thing there would be to
introduce synccond_t infra (pthread_cond_t kind of infra for syncops)
which I am planning to implement for future releases.
3) Based on 1), 2) and the fact that afr already does retries of the
indices in a loop I removed retries again in the threads.
4) After the refactor, the changes required to bring in multi-threaded
self-heal for ec would just be ~10 lines, most of it will be about
options initialization.
Our tests found that we are able to easily saturate network :-).
High level description of the final feature:
Traditionally self-heal daemon reads the indices (gfids) that need to be healed
from the brick and initiates heal one gfid at a time. Goal of this feature is
to add parallelization to the way we do self-heals in a way we do not regress
in any case but increase parallelization wherever we can. As part of this following
knobs are introduced to improve parallelization:
1) We can launch 'max-jobs' number of heals in parallel.
2) We can keep reading indices as long as the wait-q for heals doesn't go over
'max-qlen' passed as arguments to multi-threaded dir_scan.
As a first cut, we always do healing of directories in serial order one at a time
but for files we launch heals in parallel. In future we can do name-heals of dir
in parallel, but this is not implemented as of now. Reason for this is mentioned
already in '2)' above.
AFR/EC can introduce options like max-shd-threads/wait-qlength which can be set
by users to increase the rate of heals when they want. Please note that the
options will take effect only for the next crawl.

This commit exposes some issues with management encryption that prevents
GlusterFS from operating properly. This will be added again once
problems with management encryption are fixed.

If 'changelog' is enabled and 'changelog.capture-del-path' option is on
it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by
caller. 'changelog_unlink' calls this routine directly with
'loc->pargfid' resulting it being modified and point to root instead of
actual pargfid. This is a nasty bug and could cause the deletion of
entry on root directory instead on actual parent when 'loc->path' is
not present. Hence this fix to make 'pargfid' a const pointer and
'resolve_pargfid' to work on copy of pargfid.
Glusterfind session creation enables these options by default to
capture deleted entry path in changelog.
Thanks Pranith for root causing this.

Problem:
During the rename of a particular file (ec
is holding blocking inodelk on the parent
directory), if the rename of another file
under the same directory comes. EC does not
release the lock and goes ahead and renames
the "new" file with the "already held lock".
That causes rebalance process to be blocked
on a lock which has been acquired by rename.
Solution:
While rename fop comes, ec takes blocking inodelk
on old and new parent of the file. Before releasing,
every lock held by ec, it waits for some "time" to
see if that lock can be reused by the next fop.
If within this "time" some other request comes,
it releases this lock based on condition
"lock count > 1"
To get this "lock count" for rename fop, we have
implemented "pl_rename" in feature/lock. Also,
on ec side, changed the condition to release the lock
based on the type of fop and old and new parent
directories.

Commit 8fdfa0c introduced a fix to ensure cmd_history file is log rotated
properly. However with this fix fdopen() is called with mode "a" on a fd which
was not opened with O_WRONLY & O_APPEND resulting into a fdopen() failure.
Fix is to open cmd_history.log file with O_CREATE|O_WRONLY|O_APPEND mode

Issue: http://thread.gmane.org/gmane.comp.file-systems.gluster.devel/10922
The right fix for this is elaborate and intrusive, until it is in place,
this patch provides a temperory fix. This fix is necessary, as without this
libgfapi applications like qemu, samba, NFS ganesha are prone to crashes.
This patch will be reverted completely, once the actual fix gets accepted.

This patch is backport of: http://review.gluster.org/#/c/12346/
Previously if user set an option where length of key=value goes beyond
PATH_MAX (4096) character then tokenzing the option at the time of
reading configuration file will fail.
This is because of the we was having restraction in fgets to read maximum
of PATH_MAX (4096) length of character.
Consequence of this is when user try to restart glusterd, after setting
key=value length beyond PATH_MAX (4096) character, glusterd will not restart.
With this fix instead of PATH_MAX, consumer of gf_store_read_and_tokenize
function will decide the size of the buffer length.

Backport of http://review.gluster.org/12451
In replicate volumes, when a brick is added to a replicate
group, heal to the new brick should be triggered.
Also, the new brick should not be considered as source for
healing till it is up to date.
Previously, extended attributes had to be set manually on
the bricks for this to happen. This patch is part 1 patch
to automate this process.

Problem:
Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration,
1. glusterd needs to listen on default port (240007) as IPv6 TCP listner.
2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe
needs to work using ipv6 addresses.
3. Bricks needs to listen on ipv6 addresses.
All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.
Fix:
When "option transport.address-family inet6" option is present in glusterd.vol
file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved
inside brick volume files used by glusterfsd brick process when they are starting.
Tests Run:
Regression tests using ./run-tests.sh
IPv4: Regression tests using ./run-tests.sh for release-3.7 branch verified by comparing with clean repo.
IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts)
Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here
