Commit 37db7985fde9e6a5e71ae628d0b7124a27bf31c3 modernized how we
declare module dependencies on Solaris 10 and newer.
Instead of explicitly specifying recent Solaris version numbers, specify
old versions for the old method. This should be more future proof.
Thanks to Ben Kaduk for the suggestion.

The ancient way of declaring module dependencies with _depends_on has
been deprecated since SunOS 2.6 (circa 1996). The presence of the old
_depends_on symbol triggers a warning message on the console starting
with Solaris 12, and the kernel runtime loader (krtld) feature of using
the _depends_on symbol to load dependencies may be removed in a future
version of Solaris.
Convert the kernel module from the ancient _depends_on method to modern
ELF dependencies. Remove the old _depends_on symbol and specify the -dy
and -N <name> linker options to set the ELF dependencies at link time,
as recommended in the Solaris device driver developer guidelines [1].
This commit does not change the declared dependencies, which may be
vestiges of ancient afs versions.

Linux commit f74e7b33c37e vfs: remove unused have_submounts() function
(v4.10-rc2) removes have_submounts from the tree after providing a
replacement (path_has_submounts) for its last in-tree caller, autofs.
However, it turns out that OpenAFS is better off not using the new
path_has_submounts. Instead, OpenAFS could/should have stopped using
have_submounts() much earlier, back in Linux v3.18 when d_invalidate
became void. At that time, most in-tree callers of have_submounts had
already been converted to use check_submounts_and_drop back in v3.12.
At v3.18, a series of commits modified check_submounts_and_drop to
automatically remove child submounts (instead of returning -EBUSY if a
submount was detected), then subsumed it into d_invalidate. The end
result was that VFS now implicitly handles much of the housekeeping
previously called explicitly by the various filesystem d_revalidate
routines:
- shrink_dcache_parent
- check_submounts_and_drop
- d_drop
- d_invalidate
All in-tree filesystem d_revalidate routines were updated to take
advantage of this new VFS support.
Modify afs_linux_dentry_revalidate to no longer perform any special
handling for invalid dentries when D_INVALIDATE_IS_VOID. Instead, allow
our VFS caller to properly clean up any invalid dentry when we return 0.

Currently, if the client is started without any options that require
an extra thread (like -afsdb), all processes spawned by afsd will
exit. There may be some kernel threads still active, but those are
spawned by the kernel module, and are not child processes of the
parent afsd process, or anything like that.
Since we are a Type=forking service in systemd, systemd interprets
this situation to mean that the service has stopped successfully, and
then runs the ExecStop commands. So, for example, if our AFSD_ARGS in
our sysconfig is "-fakestat -afsdb", the service starts as normal. But
if it is changed to "-fakestat", then when openafs-client.service is
started, it immediately stops again.
To avoid this, turn on the systemd option RemainAfterExit, which tells
systemd that the service has not stopped if all of our processes have
exited. The client service will thus remain running until it is
stopped.

In Linux 3.15 commit 520c8b16505236fc82daa352e6c5e73cd9870cff,
inode_operation rename2() was added. It takes the same arguments as
rename(), with an added flags argument supporting the following values:
RENAME_NOREPLACE: if "new" name exists, fail with -EEXIST. Without
this flag, the default behavior is to replace the "new" existing file.
RENAME_EXCHANGE: exchange source and target; both must exist.
OpenAFS never implemented a .rename2() routine because it was optional
when introduced at Linux v3.15.
In Linux 4.9-rc1 the following commits remove the last in-tree uses of
.rename() and converts .rename2() to .rename().
aadfa8019e81 vfs: add note about i_op->rename changes to porting
2773bf00aeb9 fs: rename "rename2" i_op to "rename"
18fc84dafaac vfs: remove unused i_op->rename
1cd66c93ba8c fs: make remaining filesystems use .rename2
e0e0be8a8355 libfs: support RENAME_NOREPLACE in simple_rename()
f03b8ad8d386 fs: support RENAME_NOREPLACE for local filesystems
With these changes, it is now mandatory for OpenAFS afs_linux_rename()
to accept a 5th flag argument.
Add an autoconfig test to determine the signature of .rename(). Use this
information to implement afs_linux_rename() with the appropriate number
of arguments. Implement "toleration support" for the flags option by
treating a zero flag as a normal rename; if any flags are specified,
return -EINVAL to indicate the OpenAFS filesystem does not yet support
any flags.

Deleting an AFS directory entry (afs_dir_Delete) merely removes the
entry logically by updating the allocation map and hash table. However,
the entry itself remains on disk - that is, both the cache manager's
cache partition and the fileserver's vice partitions.
This constitutes a leak of directory entry information, including the
object's name and MKfid (vnode and uniqueid). This leaked information
is also visible on the wire during FetchData requests and volume
operations.
Modify afs_dir_Delete to clear the contents of deleted directory
entries.
Patchset notes:
This commit only prevents leaks for newly deleted entries. Another
commit in this patchset prevents leaks of partial object names upon
reuse of pre-existing deleted entries. A third commit in this
patchset prevents yet another kind of directory entry leak, when
internal buffers are reused to create or enlarge existing directories.
All three patches are required to prevent new leaks. Two additional
salvager patches are also included to assist administrators in the
cleanup of pre-existing leaks.

Summary:
Due to incomplete initialization or clearing of reused memory,
fileserver directory objects are likely to contain "dead" directory
entry information. These extraneous entries are not active - that is,
they are logically invisible to the fileserver and client. However,
they are physically visible on the fileserver vice partition, on the
wire in FetchData replies, and on the client cache partition. This
constitutes a leak of directory information.
Characterization:
There are three different kinds of "dead" residual directory entry
leaks, each with a different cause:
1. There may be partial name data after the null terminator in a live
directory entry. This happens when a previously used directory entry
becomes free, then is reused for a directory entry with a shorter name.
This may be addressed in a future commit.
2. "Dead" directory entries are left uncleared after an object is
deleted or renamed. This may be addressed in a future commit.
3. Residual directory entries may be inadvertently picked up when a new
directory is created or an existing directory is extended by a 2kiBi
page. This is the most severe problem and is addressed by this commit.
This third kind of leak is the most severe because the leaked
directory information may be from _any_ other directory residing on the
fileserver, even if the current user is not authorized to see that
directory.
Root cause:
The fileserver's directory/buffer package shares a pool of directory
page buffers among all fileserver threads for both directory reads and
directory writes. When the fileserver creates a new directory or
extends an existing one, it uses any available unlocked buffer in the
pool. This buffer is likely to contain another directory page recently
read or written by the fileserver. Unfortunately the fileserver only
initializes the page header fields (and the first two "dot" and "dotdot"
entries in the case of a new directory). Any residual entries in the
rest of the directory page are now logically "dead", but still
physically present in the directory. They can easily be seen on the
vice partition, on the wire in a FetchData reply, and on the cache
partition.
Note:
The directory/buffer package used by the fileserver is also used by the
salvager and the volserver. Therefore, salvager activity may also leak
directory information to a certain extent. The volserver vos split
command may also contribute to leaks. Any volserver operation that
creates volumes (create, move, copy, restore, release) may also have
insignificant leaks. These less significant leaks are addressed by this
commit as well.
Exploits:
Any AFS user authorized to read directories may passively exploit this
leak by capturing wire traffic or examining his local cache as he/she
performs authorized reads on existing directories. Any leaked data will
be for other directories the fileserver had in the buffer pool at the
time the authorized directories were created or extended.
Any AFS user authorized to write a new directory may actively exploit
this leak by creating a new directory, flushing cache, then re-reading
the newly created directory. Any leaked data will be for other
directories the fileserver had in the buffer pool within the last few
seconds. In this way an authorized user may sample current fileserver
directory buffer contents for as long as he/she desires, without being
detected.
Directories already containing leaked data may themselves be leaked,
leading to multiple layers of leaked data propagating with every new or
extended directory.
The names of files and directories are the most obvious source of
information in this leak, but the FID vnode and uniqueid are leaked as
well. Careful examination of the sequences of leaked vnode numbers and
uniqueids may allow an attacker to:
- Discern each layer of old directories by observing breaks in
consecutive runs of vnode and/or uniqueid numbers.
- Infer which objects may reside on the same volume.
- Discover the order in which objects were created (vnode) or modified
(uniqueid).
- Know whether an object is a file (even vnode) or a directory (odd
vnode).
Prevent new leaks by always clearing a pool buffer before using it to
create or extend a directory.
Existing leaks on the fileserver vice partitions may be addressed in a
future commit.

Currently, when we need to contact all other servers in the ubik
quorum (to create a write transaction, and send db changes, etc), we
call the ContactQuorum_* family of functions. To contact each server,
those functions follow an algorithm like the following pseudocode:
{
int rcode = 0;
int code;
int okcalls = 0;
for (ts = ubik_servers; ts; ts = ts->next) {
if (ts->up) {
code = contact_server(ts);
if (code) {
rcode = code;
} else {
okcalls++;
}
}
}
if (okcalls + 1 >= ubik_quorum) {
return 0;
} else {
return rcode;
}
}
This means that if we successfully contact a majority of ubik sites,
we return success, even if some sites returned an error. If most sites
fail, then we return an error (we arbitrarily pick the last error we
got).
This means that in most situations, a successful write transaction is
guaranteed to have been transmitted to a majority of ubik sites, so
the written data cannot be lost (at least one of the sites that got
the new data will be in a future elected quorum).
However, if a site is already known to be down (ts->up is 0), then we
skip trying to contact that site, but we also don't set any errors.
This means that if a majority of sites are already known to be down
(ts->up is 0), then we can indicate success for a write transaction,
even though the relevant data has not been written to a majority of
sites. In that situation, it is possible to lose data.
Most of the time this is not possible, since a majority of sites must
be 'up' for the sync site to be elected and to allow write
transactions at all. There are a few ways, though, in which we can get
into a situation where most other sites are 'down', but we still let a
write transaction go through.
An example scenario:
Say we have sites A, B, and C. All 3 sites come up at the same time,
and A is the lowest IP so it starts an election (after around BIGTIME
seconds). Right after A is elected the sync site, sites B and C will
have 'lastYesState' set to 0, since site A hasn't yet sent out a
beacon as the sync site.
A client can then start a write to the ubik database on site A, which
site A will allow since it's the sync site (and presumably all the
relevant recovery flags are set). Site A will try to contact sites B
and C for a DISK_Begin call, but lastYesState is set to 0 on those
sites. This will cause DISK_Begin to return UNOQUORUM
(urecovery_AllBetter will return 0, because uvote_HaveSyncAndVersion
will return 0, because lastYesState is not set).
So site A will get a UNOQUORUM error from sites B and C, and so site A
will set 'ts->up' to 0 for sites B and C, and will return UNOQUORUM to
the client. The client may then try to retry the call (because
UNOQUORUM is not treated as a 'global' error in ubikclient.c's
ubik_Call_New), or another client write request could come in. Now
that 'ts->up' is unset for both sites B and C, we skip trying to
contact any remote sites, and the ContactQuorum functions will return
success. So the ubik write will go through successfully, but the new
data will only be on site A.
At this point, if site A crashes, then sites B and C will elect a
quorum, and will not have the modifications that were written to site
A (so the data written to site A is lost). If site A stays up, then it
will go through database recovery, sending the entire database file to
sites B and C.
In addition, it's very possible in this scenario for a client to write
to the database, and then try to read back data and confusingly get a
different result. For example, if someone issues the following two
commands while triggering the above scenario:
$ pts createuser testuser
$ pts examine testuser
If the second command contacts site B or C, then it will always fail,
saying that the user doesn't exist (even though the first command
succeeded). This is because sites B and C don't have the new data
written to site A, at least temporarily. While this confusing behavior
is not completely avoidable in ubik (this can always happen
'sometimes' due to network errors and such), with the scenario
described here, it happens 100% of the time.
The general scenario described above can also happen if sites B and C
are suddenly legitimately unreachable from site A, instead of throwing
the UNOQUORUM error. All of the steps are pretty much the same, but
there is a bit of a delay while we wait for the DISK_Begin call to
fail.
To fix this, do not let 0 be returned if a quorum has not been
reached. In some sense, UNOQUORUM could *always* be returned in
that case, but it is more in keeping with historical behavior to
return a "real" error if there is one available.
It is somewhat questionable whether we should even be propagating
errors received from calls like DISK_Begin/DISK_Commit to the ubik
client (e.g. if we get a -1 from trying to contact a remote site, we
return -1 to the client, so the client may think it couldn't reach the
site at all). But this commit does not change any of that logic, and
should only change behavior when a majority of sites have 'ts->up'
unset. A later commit might effect the change to always return
UNOQUORUM and ignore the actual error values from the DISK_ calls,
but that is not needed to fix the immediate issue.
An important note:
Before this commit, there was a window of about 15 seconds after a
sync site is elected where a write to the ubik db would appear to be
successful, but would only modify the ubik db on the sync site.
(Details described above.) With this commit, writes during that
15-second window will instead fail, because we cannot guarantee that
we won't lose that data. If someone relies on 'udebug' data from the
sync site to let them know when writes will go through successfully,
this commit could appear to cause new errors.

Previously, we would set -fno-strict-aliasing only when
--enable-checking was given to configure but not
--enable-checking=all. The intent seems to have been to
only warn about strict aliasing violations when --enable-checking=all
is in use, but that there was no need to disable the strict-aliasing
diagnostics when -Werror was not enabled.
Unfortunately, -fno-strict-aliasing affects not only the diagnostics
emitted by the compiler, but also the code generation! So we were
leaving the normal (no --enable-checking) case with the compiler
assuming C's strict aliasing rules. The OpenAFS codebase has
historically not been strict-aliasing safe (for example,

as the compiler using the C strict aliasing rules to make
optimizations that exposed the invalid program code.
To avoid futher surprises due to new compiler optimizations
that utilize the C strict aliasing rules, always disable
strict aliasing except when --enable-checking=all is used.

Currently, the ubik recovery code will always set UBIK_RECFOUNDDB
during recovery, after asking all other sites for their dbversions.
This happens regardless of how many sites we were actually able to
successfully contact, even if we couldn't contact any of them.
This can cause problems when we are unable to contact a majority of
sites with DISK_GetVersion. Since, if we haven't contacted a majority
of sites, we cannot say with confidence that we know what the best db
version available is (which is what UBIK_RECFOUNDDB represents; that
we've found which database is the one we should be using). This can
also result in UBIK_RECHAVEDB in a similar situation, indicating that
we have the best db version locally, even though we never actually
asked anyone else what their db version was.
For example, say site A is the sync site going through recovery, and
DISK_GetVersion fails for the only other sites B and C. Site A will
then set UBIK_RECFOUNDDB, and will claim that site A has the best db
version available (UBIK_RECHAVEDB). This allows site A to process ubik
write transactions (causing the db to be labelled with a new epoch),
or possibly to send the db to the other sites via DISK_SendFile, if
they quickly become available during recovery. Ubik write transactions
can succeed in this situation, because our ContactQuorum_* calls will
succeed if we never try to contact a remote site ('rcode' defaults to
0).
This situation should be rather rare, because normally a majority of
sites must be reachable by site A for site A to be voted the sync site
in the first place. However, it is possible for site A to lose
connectivity to all other sites immediately after sync site election.
It is also possible for site A to proceed far enough in the recovery
process to set UBIK_RECHAVEDB before it loses its sync site status.
As a result of all of this, if a site with an old database comes
online and there are network connectivity problems between the other
sites and a ubik write request comes in, it's possible for the "old"
database to overwrite the "new" database. This makes it look as if the
database has "rolled back" to an earlier version.
This should be possible with any ubik database, though how to actually
trigger this bug can change due to different ubik servers setting
different network timeouts. It is probably the most likely with the
VLDB, because the VLDB is typically the most frequently written
database.
If a VLDB reverts to an earlier version, it can result in existing
volumes to appear to not exist in the VLDB, and can result in new
volumes re-using volume IDs from existing volumes. This can result in
rather confusing errors.
To fix this, ensure that we have contacted a majority of sites with
DISK_GetVersion before indicating that we have located the best db
version. If we've contacted a majority of sites, then we are
guaranteed (under ubik assumptions) that we've found the best version,
since previous writes to the database should be guaranteed to hit a
majority of sites (otherwise they wouldn't be successful).
If we cannot reach a majority of sites, we just don't set
UBIK_RECFOUNDDB, and the recovery process restarts. Presumably on the
next iteration we'll be able to contact them, or we'll lose sync site
status if we can't reach the other sites for long enough.

might have to be called several times. If so, the
memory previously allocated should be released.
