OPENAFS-SA-2017-001: rx: Sanity-check received MTU and twind values
Rather than blindly trusting the values received in the
(unauthenticated) ack packet trailer, apply some minmial sanity checks
to received values. natMTU and regular MTU values are subject to
Rx minmium/maximum packet sizes, and the transmit window cannot drop
below one without risk of deadlock.
The maxDgramPackets value that can also be present in the trailer
already has sufficient sanity checking.
Extremely low MTU values (less than 28 == RX_HEADER_SIZE) can cause us
to set a negative "maximum usable data" size that gets used as an
(unsigned) packet length for subsequent allocation and computation,
triggering an assertion when the connection is used to transmit data.

afs: add afsd -inumcalc option
This commit adds the afsd -inumcalc command line switch to specify the
inode number calculation method in a platform neutral way.
Inode numbers reported for files within the AFS filesystem are generated
by the cache manager using a calculation which derives a number from a
FID. Long ago, a new type of calculation was added which generates inode
numbers using a MD5 message digest of the FID. The MD5 inode number
calculation variant is computationally more expensive but greatly
reduces the chances for inode number collisions.
The MD5 calculation can be enabled on the Linux cache manager using the
Linux sysctl interface. Other than the sysctl method of selecting the
inode calculation type, the MD5 inode number calculation method is not
specific to Linux.
This change introduces a command-line option which accepts a value to
indicate the calculation method, instead of a simple flag to enable MD5
inode numbers. This should allow for new inode calculation methods
in the future without the need for additional afsd command-line flags.
Two values are currently accepted for -inumcalc. The value of 'compat'
specifies the legacy inode number calculation. The value 'md5' indicates
that the new MD5 calculation is to be used.

However, 230dcebcd61064cc9aab6d20d34ff866a5c575ea moved the global

vol: detach offline volumes on dafs
Taking a volume offline always clears the inService bit. Taking a
volume out of service also takes it offline. Therefore, if the
inService flag is false, the volume in question should be offline.
On dafs, an offline volume should be unattached.
The attach2() function does not change the state of the volume received
as an argument to unattached when the inService flag is false. Instead,
this function changes the state of the volume in question to
pre-attached and returns VNOVOL to the client. As result, subsequent
accesses to this volume will make the server try and fail to attach
this offline volume over and over again, writing to the FileLog each
time.
To fix this problem, detach the volume received as an argument if the
inService flag is false. Since the new state of this volume will be
unattached, subsequent accesses will not hit attach2().
This situation where a volume is not offline but is also not in service
can occur if a volume is taken offline with vos offline and some time
later the DAFS fileserver is shutdown and restarted; the volume is
placed into the preattach state by default when the server restarts.
Each access to the volume by clients then causes the fileserver to
attempt to attach the volume, which fails, since the in-service flag in
the volume header is false from the previous vos offline. The
fileserver will log a warning to the FileLog on each attempt to attach
the volume, and this will fill the FileLog with duplicate messages
corresponding to the number of attempted accesses.

afs: shake harder in shake-loose-vcaches
Linux based cache managers will allocate vcaches on demand and
deallocate batches of vcaches in the background. This feature is called
dynamic vcaches.
Vcaches to be deallocated are found by traversing the vcache LRU list
(VLRU) from the oldest vcache to the newest. Up to a target number of
vcaches are attempted to be evicted. The afs_xvcache lock protecting
the VLRU may be dropped and re-acquired while attempting to evict a
vcache. When this happens, it is possible the VLRU may have changed, so
the traversal of the VLRU is restarted. This restarting of the VLRU
transversal is limited to 100 iterations to avoid looping indefinitely.
Vcaches which are busy cannot be evicted and remain in the VLRU. When a
busy cache was not evicted and the afs_xvache lock was dropped, the VLRU
traversal is restarted from the end of the VLRU. When the busy vcache is
encountered on the retry, it will trigger additional retries until the
loop limit is reached, at which point the target number of vcaches will
not be deallocated.
This can leave a very large number of unbusy vcaches which are never
deallocated. On a busy machine, tens of millions of unused vcaches can
remain in memory. When the busy vcache at the end of the VLRU is finally
evicted, the log jam is broken, and the background deamon will hold the
afs_xvcache lock for an excessively long time, hanging the system.
Fix this by moving busy vcaches to the head of the VLRU before
restarting the VLRU traversal. These busy vcaches will be skipped when
retrying the VLRU traversal, allowing the cache manager to make progress
deallocating vcaches down to the target level.
This was already done on the mac osx platform while attempting to evict
vcaches. Move the code to move busy vcaches to the head of the VLRU up
the the platform agnostic caller.

Commit c89fd17df1032ec2eacc0d0c9b73e19c5e8db7d2 introduced an explicit

Several components of libafs which require cred.h were picking it by
including sched.h.
Instead, explicitly add an include for cred.h. cred.h begins with a
customary one-shot to prevent multiple loads:
#ifndef _LINUX_CRED_H
#define _LINUX_CRED_H
Therefore we don't need a new autoconf test or preprocessor conditional
to prevent redundant includes on older Linux releases.

statx: Add a system call to make enhanced file info available
The Linux getattr inode operation is altered to take two additional
arguments: a u32 request_mask and an unsigned int flags that indicate
the synchronisation mode. This change is propagated to the
vfs_getattr*() function.
- int (*getattr) (struct vfsmount *, struct dentry *, struct kstat *);
+ int (*getattr) (const struct path *, struct kstat *,
+ u32 request_mask, unsigned int sync_mode);
The first argument, request_mask, indicates which fields of the statx
structure are of interest to the userland call. The second argument,
flags, currently may take the values defined in
include/uapi/linux/fcntl.h and are optionally used for cache coherence:
(1) AT_STATX_SYNC_AS_STAT tells statx() to behave as stat() does.
(2) AT_STATX_FORCE_SYNC will require a network filesystem to
synchronise its attributes with the server - which might require
data writeback to occur to get the timestamps correct.
(3) AT_STATX_DONT_SYNC will suppress synchronisation with the server in
a network filesystem. The resulting values should be considered
approximate.
This patch provides a new autoconf test and conditional compilation to
cope with the changes in our getattr implementation.

SOLARIS: prevent BAD TRAP panic with Studio 12.5
Starting with Solaris Studio 12.3, it is documented that Solaris kernel
modules (such as libafs) must not use any floating point, vector, or
SIMD/SSE instructions on x86 hardware. However, each new Studio
compiler release (12.4 and especially 12.5) is more likely to use these
types of instructions by default.
If the libafs kernel module includes any forbidden kernel instructions,
Solaris will panic the system with:
BAD TRAP: type=7 (#nm Device not available)
Provide a new autoconfig test to specify the required compiler options
(-xvector=%none -xregs=no%float) when building the OpenAFS kernel module
for Solaris, so that no invalid x86 instructions are used.
In addition, reinstate default kernel module optimization for Solaris.
It had been disabled in commit 80592c53cbb0bce782eb39a5e64860786654be9f
to address this same issue in Studio 12.3 and 12.4. However, Studio
12.5 started using some SSE instructions even with no optimization.
This commit has been tested with OpenAFS master and Studio 12.5 at all
optimization levels (none, -xO1 through -xO5) and verified to contain no
XMM register instructions via the following command:

SOLARIS: Use AFS_PAG_ONEGROUP_ENV for Solaris 11
On Solaris 11 (specifically, Solaris 11.1+), the supplemental group
list for a process is supposed to be sorted. Starting with Solaris
11.2, more authorization checks are done that assume the list is
sorted (e.g., to do a binary search), so having them out of order
can cause incorrect behavior. For example:
$ echo foo > /tmp/testfile
$ chmod 660 /tmp/testfile
$ sudo chown root:daemon /tmp/testfile
$ cat /tmp/testfile
foo
$ id -a
uid=100(adeason) gid=10(staff) groups=10(staff),12(daemon),20(games),21(ftp),50(gdm),60(xvm),90(postgres)
$ pagsh
$ cat /tmp/testfile
cat: cannot open /tmp/testfile: Permission denied
$ id -a
uid=100(adeason) gid=10(staff) groups=33536,32514,10(staff),12(daemon),20(games),21(ftp),50(gdm),60(xvm),90(postgres)
Solaris sorts the groups given to crsetgroups() on versions which
required the group ids to be sorted, but we currently manually put our
PAG groups in our own order in afs_setgroups(). This is currently
required, since various places in the code assume that PAG groups are
the first two groups in a process's group list.
To get around this, do not require the PAG gids to be the first two
gids anymore. To more easily identify PAG gids in group processes, use
a single gid instead of two gids to identify a PAG, like modern Linux
currently uses (under the AFS_PAG_ONEGROUP_ENV). High-numbered groups
have been possible for quite a long time on Solaris, allegedly further
back than Solaris 8. Only do this for Solaris 11, though, to reduce
the platforms we affect.

LINUX: Debian/Ubuntu build regression on kernel 3.16.39
Now that kernel 4.9 has hit jessie-backports, it becomes desirable to
also backport the associated openafs patches.
Unfortunately, Linux-4.9-inode_change_ok-becomes-setattr_prepare.patch
causes a build failure against jessie's current default kernel,
3.16.39-1, due to the fact that setattr_prepare() is available (it was
cherrypicked to address CVE-2015-1350) but file_dentry() is not (it was
introduced in kernel 4.6).
This makes it difficult to have a version of openafs for jessie that
supports both kernels.
To deal with this, follow the implementation of file_dentry() in 4.6,
and simplify it to account for the lack of d_real() support in older
kernels.
Note that inode_change_ok() has been added back to 3.16.39-1 to avoid
ABI changes. That means the current openafs packages in jessie continue
to work with kernel 3.16.39-1 since they do not include
Linux-4.9-inode_change_ok-becomes-setattr_prepare.patch.

Linux 4.10: have_submounts is gone
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.

systemd: RemainAfterExit in openafs-client.service
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.

Linux 4.9: inode_operation rename now takes flags
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.

Linux commit 81243eacfa40 "cred: simpler, 1D supplementary groups"

The GROUP_AT macro is also removed from the tree.
