ea9e5e8519 afs: Handle osi_NewVnode failures
Currently, code inside afs_vcache.c assumes that osi_NewVnode always
returns non-NULL, which means that osi_NewVnode must panic if it
cannot create a new vnode.

All of the callers of afs_GetVCache, afs_NewVCache, etc, already
handle getting a NULL return, though (after all, the given fid may not
exist or be inaccessible due to network errors, etc). So, just
propagate NULL returns from osi_NewVnode up to our callers, to avoid
panics in these situations.

Modify osi_NewVnode on many arches to return an error on allocation
failure, instead of panic'ing.

e1e5df918f stats: incorrect clock square algorithm
Since the original IBM code import, OpenAFS has an algorithm for
squaring clock values, implemented identically in three different
places.  This algorithm does not account correctly for microsecs
overflow into seconds, resulting in incorrect "sum-of-squares" values
for queue and execution time in several OpenAFS performance utilities.

Specifically, this code:

        t1.tv_usec += (2 * t2.tv_sec * t2.tv_usec) % 1000000                   \
                      + (t2.tv_usec / 1000)*(t2.tv_usec / 1000)                \
                      + 2 * (t2.tv_usec / 1000) * (t2.tv_usec % 1000) / 1000   \
                      + (((t2.tv_usec % 1000) > 707) ? 1 : 0);                 \

Can allow for the tv_usec field to be increased by a theoretical max
of around:

        t1.tv_usec += 999998                                                   \
                      + 999*999                                                \
                      + 2 * 999 * 999 / 1000                                   \
                      + 1;                                                     \

Or:

        t1.tv_usec += 1999996;                                                 \

If t1.tv_usec is already 999999, after this calculation its value
could be as high as 2999995. So just checking once if t1.tv_usec is
over 1000000 is not sufficient, since the resulting value (1999995) is
still over 1000000.

Correct all implementations by repeatedly checking if tv_usec is over
1000000 after the above calculation:

18c345a9f8 rxstats: correctly distinguish client and server stats
Commit d3eaa39da3693bba708fa2fa951568009e929550 'rx: Make the rx_call
structure private' inadvertently caused all rxstats (aka rpcstats) to be
recorded as client stats by hardcoding the value for isServer to 1.

Therefore, when peer or process rxstats are enabled for a OpenAFS
component, the rxstat_get_process and rxstat_get_peer utilities will
erroneously report both client and server stats as "accessed as a client".

This is particularly problematic for ubik VOTE_* and DISK_* RPC stats,
for which a given ubik server may be both client and server over time.
In this case, both client and server stats are conflated into the same
"accessed as a client" counters.

Instead, properly pass the value of isServer from
rx_RecordCallStatistics through to rxi_IncrementTimeAndCount.

Note to maintainers:
This bug is only in master and all 1.8.x releases; no 1.6.x releases are
affected.

Note:
Confusingly, isServer=1 indicates client stats and isServer=0 indicates
server stats.  However, this is a quirk of the original implementation
and wire format of the RXSTATS_* RPCs and cannot be changed.  isServer
is actually shorthand for "remote is server"; thus all RPC client stubs
record their rxstats with isServer == 1, and all RPC server stubs record
their rxstats with isServer == 0.

47d809d443 bozo: Log each dir and file with bad access rights
The bosserver directory and file access check stops after finding one
directory or file with incorrect permissions or owner. A log message is
written for this first one found, but more than one directory or file
may have incorrect access rights.

Instead check all of them so the bosserver logs a warning message for
each incorrect director or file permission found.  This should make it
easier to fix all of the file permission problems at once.

4e85324729 xstat: prevent CPU loop when -period 0
Historically xstat_cm_test and xstat_fs_test have supported option
'-period <mm>' to specify continuous operaiton for a length of time.  If
'-period 0' was specified, both programs exited immediately.

Beginning with commits 2c1a7e47336c8f8d14dd6c65d53925a9e0e87c66 'xstat:
add xstat_*_Wait functions' and 6b67cac432043a43d7cdfa6af972ab54412aff94
'convert xstat and friends to pthreads', xstat_cm_test and xstat_fs_test
now support -period 0 to run "forever".  This support is implemented in
xstat_cm_Wait and xstat_fs_Wait, respectively.  Although the "wait
forever" logic was added to allow consolidation of similar code in
afsmonitor, it also changed how xstat_cm_test and xstat_fs_test behave
for '-period 0'.

Unfortunately, there is a bug in this support, at least when running on
pthreads.  After the initial 24 minute timer expires, the while (1) will
repeatedly run select with a timeout that is now 0.  This causes the
while loop to consume 100% of the CPU on which this thread is
dispatched.

Instead, modify the wait-forever logic to specify NULL for the select()
timeout value.  Also update the man page to document that '-period 0'
means forever.

74f46e0912 afs: Return to userspace after AFS_NEW_BKG reqs
Currently, for AFS_NEW_BKG, background daemons run in the context of a
normal user process (afsd), in order to return to run
userspace-handled background ops. For non-AFS_NEW_BKG when
AFS_DAEMONOP_ENV is defined, background daemons run as kernel threads
instead, and have no corresponding userspace process.

On LINUX, whether or not we run as a kernel thread has some odd
side-effects: at least one example of this is how open file handles
(struct file) are treated when closed. When the last reference to a
struct file is closed, the final free is deferred to an asynchronous
call to be executed "later", in order to avoid issues with lock
inversion. For kernel threads, "later" means the work is schedule on
the global system work queue (schedule_work()), but for userspace
processes, it is scheduled on the task work queue (task_work_add()),
which is run around when the thread returns to userspace. For
background daemons, we never return from the relevant syscall until we
get a userspace background request (or the client is shutting down),

Commit ca472e66 (LINUX: Turn on AFS_NEW_BKG) changed LINUX to use
AFS_NEW_BKG background daemons, so background requests now run as a
normal userspace process, and last-reference file closes are deferred.
Since we may never return to userspace, this means that our file
handles (used for accessing the disk cache) may never get freed,
leading to an unbounded number of file handles remaining open.

This can be seen by seeing the first value in /proc/sys/fs/file-nr
growing without bound (possibly slowly), as accessing /afs causes
background requests. Eventually the number of open files can exceed
the /proc/sys/fs/file-max limit, causing further file opens to fail,
causing various other problems and potentially panics.

To avoid this issue, define a new userspace background op, called
AFS_USPC_NOOP, which gets returned to the afsd background daemon
process. When afsd sees this, it just does nothing and calls the
AFSOP_BKG_HANDLER syscall again, to go into the background daemon loop
again. In afs_BackgroundDaemon, we return the AFS_USPC_NOOP op
whenever there are no pending background requests, or if we've run 100
background requests in a row without a break. This causes us to return
to userspace periodically, preventing any such task-queued work from
building up indefinitely.

Do this for all platforms (currently just LINUX and DARWIN), in order
to simplify the code, and possibly avoid other similar issues, since
staying inside a syscall for so long while doing real work is arguably
weird.

Add a documentation comment block for afs_BackgroundDaemon while we're
here.

Thanks to mvitale@sinenomine.net for discovering the file leak.

bc6f50ca0c dir: Set srcdir correctly in src/dir/test
srcdir is a magic variable that needs to be set to @srcdir@, not some
relative path like ../../.. (which will usually be somewhere in the
objdir, not srcdir). Set it correctly in here.

Without this, objdir builds can fail with:

    make[4]: Entering directory '...obj/src/dir/test'
    make[4]: *** No rule to make target 'dtest.o', needed by 'dtest'.  Stop.

Which happens because the automatic rule for dtest.o can't be
constructed, since we cannot find dtest.c automatically because srcdir
isn't set properly.

This has been broken since commit 37b4195d (dtest-20021111), but was
not noticeable until commit 192a2ff4 (dir: make dtest buildable
again), since that caused dtest to actually get built.

Also set LIBS correctly in here, using the conventional ${TOP_LIBDIR},
since ${srcdir} no longer points to "../../..".

1aa7d3c199 afs: refactor directory checking in DRead
Commit d566c1cf874d15ca02020894ff0af62c4e39e7bb
'dread-do-validation-20041012' modified directory checking (in the
afs_buffer.c implementation of DRead()) to use size information passed
to DRead, rather than obtained from the cache via afs_CFileOpen.

Because this directory checking does not require any information from
the cache buffers or the cache partition, we can make the check right
away, before searching the cache buffers or calling afs_newslot.

To clarify and simplify, move the directory sanity checking logic to the
beginning of DRead.  Remove the afs_newslot cleanup logic which is no
longer needed.

While here, add Doxygen comments for DRead.

7cc6b97ad2 makesrpm: Support custom version strings
The makesrpm.pl script generates a source RPM by creating a temporary
rpmbuild workspace, populating the SOURCES and SPECS directories in that
workspace, running rpmbuild to build the source RPM, and finally copying
the resulting source RPM out of the temporary workspace.

The name of the source RPM file created by rpmbuild depends on the
package version and release strings. Unfortunately, the format of the
source RPM file name changed around OpenAFS 1.6.0, so makesrpm.pl has
special logic to find the version string and extra code depending on the
detected OpenAFS version.

Instead of trying to predict the name of the resulting source RPM file
from the OpenAFS version string, and having different logic for old
versions of OpenAFS, use a filename glob to find resulting source RPM
file name in the temporary rpmbuild workspace.

Remove the major, minor, and patch level variables, which were only used
to guess the name of the resulting source RPM file name.

Convert '-' characters to '_' in the package version and package
release, since the '-' character is reserved by rpm as a field
separator.

While here, add the --dir option to specify the path of the generated
source RPM, and change the 'srpm' makefile target to use the new --dir
option, instead of changing the current directory before running
makesrpm.pl.  Also, add a dependency on the 'dist' makefile target,
since the the source and document tarballs are required to build the
source RPM.

Add pod documentation and add the --help (-h) option to print a brief
help message, and add the --man option to print the full man page.

With this change, we can build a source RPM even when the .version file
in the src.tar.bz file has a custom format or was created from a
checkout of the master branch or other non-release reference.

c4f853aa00 UKERNEL: Build linktest with COMMON_CFLAGS
Currently, 'linktest' in libuafs is built with a weird custom rule
that specifies several various CFLAGS and LDFLAGS, etc. One
side-effect of this is that linktest is built without specifying -O,
even if optimization is otherwise enabled.

Normally nobody would care about the optimization of linktest, since
it's never supposed to be run, but this can cause an error when
building with -D_FORTIFY_SOURCE=1 on some systems (such as RHEL7):

    In file included from /usr/include/sys/types.h:25:0,
                     from /.../src/config/afsconfig.h:1485,
                     from /.../src/libuafs/linktest.c:15:
    /usr/include/features.h:330:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
     #  warning _FORTIFY_SOURCE requires compiling with optimization (-O)
        ^
    cc1: all warnings being treated as errors
    make[3]: *** [linktest] Error 1

For now, to fix this just include $(COMMON_CFLAGS) in the flags we
give for linktest, so $(OPTMZ) also gets pulled in, and building
linktest gets a little closer to a normal compilation step.

16bae98ec5 INSTALL: document the minimum Linux kernel level
The change associated with gerrit #14300 removed support for older
Linux kernels (2.6.10 and earlier).

The commit 'Import of code from autoconf-archive' (d8205bbb4) introduced
a check for Autoconf 2.64.  Autoconf 2.64 was released in 2009.

The commit 'regen.sh: Use libtoolize -i, and .gitignore generated
build-tools' (a7cc505d3) introduced a dependency on libtool's  '-i'
option.  Libtool supported the '-i' option with libtool 1.9b in 2004.

Update the INSTALL instructions to document a minimum Linux kernel
level and the minimum levels for autoconf and libtool.

Notes: RHEL4 (EOL in 2017) had a 2.6.9 kernel and RHEL5 has a 2.6.18
kernel. RHEL5 has libtool 1.5.22 and autoconf 2.59, RHEL6 has libtool
2.2.6 and autoconf 2.63, and RHEL7 has libtool 2.4.2 and autoconf 2.69.

b968875a34 afs: Avoid NatPing event on all connection
Inside release_conns_user_server, connection vector is traversed and after
destroying a connection new eligible connection is found on which NatPing
event will be set. Ideally there should be only one connection on which
NatPing should be set but in current code while traversing all connection
of server a NatPing event is set on all connections to that server. In
cases where we have large number of connection to a server this can lead
to huge number of “RX_PACKET_TYPE_VERSION” packets sent to a server.
Since this happen during Garbage collection of user structs, to simulate
this issue below steps were tried

  - had one script which “cd” to a volume mount and then script sleeps for
    large time.
  - Ran one infinite while loop where above script was called using PAG
    based tokens (As new connection will be created for each PAG)
  - Instrumented the code, so that we hit above code segment where NatPing
    event is set. Mainly reduced NOTOKTIMEOUT to 60 sec.

To fix this issue set NatPing on one connection and once it is set break
from “for” loop traversing the server connection.

291bad659e vos: avoid 'half-locked' volume after interrupted 'vos rename'
Reported symptoms:

If a 'vos rename' is interrupted after it has locked the volume and
replaced the VLDB entry, but before it has unlocked the volume, the
volume will remain locked.  However, the locked volume will NOT be
listed as locked in any vos commands that display locked status (see
below for details).

Background:

Most vos write operations lock the VLDB volume entry before proceeding,
then release the volume lock when finished.  This is accomplished via
VL_SetLock and VL_ReleaseLock, respectively.

VL_SetLock always sets these members in the VLDB volume entry:
- flags is modified to set the required VLOP_* code bit as specified
- LockAFSid is set to 0 (never implemented)
- LockTimestamp is set to the current time

VL_ReleaseLock always sets them as follows:
- flags is cleared of any VLOP_* code bit
- LockAFSid is set to 0 (never implemented)
- LockTimestamp is set to 0

VL_ReplaceEntry(N) may also optionally clear each of these members:
- flags operation bits may be explicitly cleared via LOCKREL_OPCODE
- LockAFSid may be explicitly cleared via LOCKREL_AFSID
- LockTimestamp may be explicitly cleared via LOCKREL_TIMESTAMP

When all 3 options are specified, VL_ReplaceEntry also does the
functional equivalent of a VL_ReleaseLock.  Most vos operations use this
method.  However, when no lock release options are specified on
VL_ReplaceEntry(N), the VLDB entry is simply replaced with the supplied
entry.  This includes whatever flags values are specified in the
supplied entry; therefore, this amounts to an additional, implicit way
to set or modify the flags.

Root cause:

'vos rename' (UV_RenameVolume) is the only vos operation that does all
of the following things:
- accepts a replacement volume entry that was obtained before VL_SetLock
  (and thus does NOT have any lock flags set)
- issues VL_SetLock (which sets the lock flag in the VLDB)
- issues VL_ReplaceEntry(N) with the original unlocked entry, and with
  no lock release options (thus with explicit intent to leave the lock
  flag unchanged, but inadvertently doing an implicit clear of the lock
  flag in the VLDB)
- (performs some additional volserver work)
- issues VL_ReleaseLock to release the volume lock

Therefore, if 'vos rename' is cancelled or killed before reaching the
final VL_ReleaseLock step, the VLDB entry is left with the lock flags
cleared but the LockTimestamp still set.  As we will see below, this
'half-locked' state produces confusing results from other vos commands.

Detection of locked state:

The 'vos lock' command (and all other vos commands that issue
VL_SetLock) use the lock timestamp to determine if a volume is locked.

However, several other vos commands ('vos listvldb <vol>', 'vos examine
<vol>', 'vos listvldb -locked') use the VLDB entry's lock flags (not the
lock timestamp) to determine if the volume is locked.  Therefore, if the
lock flags have been cleared but the lock timestamp is still set, these
commands fail to detect that the volume is still locked.  Yet an
administrator's 'vos lock <volume>' will still fail with:

  Could not lock VLDB entry for volume <volume>
  VLDB: vldb entry is already locked

This is the external manifestation of the 'half-locked' state.

Workaround and fix:

This scenario has a simple workaround: 'vos unlock <volume>'.  However,
to avoid this confusing outcome in the first place, modify the 'vos
rename' logic so that the lock flags are no longer inadvertently
cleared.  Now, if the 'vos rename' is interrupted before the volume is
unlocked, it will still appear locked in normal vos command output.

904f5bd398 vlserver: fix missing read-only entries from ListAttributesN2
The ListAttributesN2() RPC can fail to list read-only entries under
certain circumstances. This RPC is used by the `vos listvldb` command to
retrieve vldb entries (unless the -name option is given). The `vos
listvldb` command fails to list volume entries when run with the
'-server' option for volumes that have read-only replicas, but have not
been released.

Consider the following example volume:

    $ vos create fs1.example.com a test
    $ vos addsite fs1.example.com a test
    $ vos addsite fs2.example.com a test
    $ vos listvldb
    ...
    test
        RWrite: 536870921
        number of sites -> 3
           server fs1.example.com partition /vicepa RW Site
           server fs1.example.com partition /vicepa RO Site  -- Not released
           server fs2.example.com partition /vicepa RO Site  -- Not released

`vos listvldb` fails to find the volume when the search is limited to
server 'fs2':

    $ vos listvldb -server fs2.example.com
    VLDB entries for server fs2.example.com
    Total entries: 0

Instead of the expected results:

    $ vos listvldb -server fs2.example.com
    test
        RWrite: 536870921
        number of sites -> 3
           server fs1.example.com partition /vicepa RW Site
           server fs1.example.com partition /vicepa RO Site  -- Not released
           server fs2.example.com partition /vicepa RO Site  -- Not released

This situation makes it difficult to remove old server addresses from
the vldb.  In this situation, 'vos remaddrs' and 'vos changeaddr
-remove' commands will complain the server addresses are still in use by
volume entries, however running 'vos listvldb -server' will not show
which volumes entries are in use.

The entries are not listed for unreleased volumes because the
ListAttributesN2() RPC is currently checking the volume VLF_ROEXISTS
flag, instead of the server site flags (serverFlags) to determine when
the entry is a read-only site. The volume VLF_ROEXISTS flag is set when
a volume is released.

To fix this, make ListAttributesN2 check for the VLSF_ROVOL site flag,
instead of the VLF_ROEXISTS entry flag.

Linux-5.9-rc1 commit 'fs: remove the HAVE_UNLOCKED_IOCTL and

The support for unlocked_ioctl and compat_ioctl were introduced in

Remove references to HAVE_UNLOCKED_IOCTL and HAVE_COMPAT_IOCTL using
the assumption that they were always defined.


Notes:

With this change, building against kernels 2.6.10 and older will fail.
RHEL4 (EOL in March 2017) used a 2.6.9 kernel.  RHEL5 uses a 2.6.18
kernel.

In linux-2.6.33-rc1 the commit messages for "staging: comedi:

remove check for HAVE_COMPAT_IOCTL" (5d7ae225) both state that all new
kernels have support for unlocked_ioctl/compat_ioctl so the checks can
be removed along with removing support for older kernels.

f5051b87a5 vos: avoid CreateVolume when restoring over an existing volume
Currently, the UV_RestoreVolume2 function always attempts to create a
new volume, even when doing a incremental restore over an existing
volume.  When the volume already exists, the volume creation operation
fails on the volume server with a VVOLEXISTS error. The client will then
attempt to obtain a transaction on the existing volume. If a transaction
is obtained, the incremental restore operation will proceed. If a full
restore is being done, the existing volume is removed and a new empty
volume is created.

Unfortunately, the failed volume creation is logged to by the volume
server, and so litters the log file with:

    Volser: CreateVolume: Unable to create the volume; aborted, error code 104

To avoid polluting the volume server log with these messages, reverse
the logic in UV_RestoreVolume2. Assume the volume already exists and try
to get the transaction first when doing an incremental restore. Create a
new volume if the transaction cannot be obtained because the volume is
not present.  When doing a full restore, remove the existing volume, if
one exists, and then create a new empty volume.

eccd4b9778 afs: Always define our own osi_timeval32_t
Since OpenAFS 1.0, osi_GetTime has taken a timeval-like pointer, which
contains 32-bit fields (the actual type has been called either
osi_timeval_t or osi_timeval32_t over time). For platforms that have a
native timeval-like type with 32-bit fields, we just define
osi_timeval32_t to that type, and elsewhere we define our own struct
to be osi_timeval32_t. For platforms that use the native timeval, we
can then define osi_GetTime() to just be, e.g., microtime().

This approach is difficult to maintain, though, because we must keep
track of whether 'struct timeval' contains 32-bit fields on each
platform, which can depend on many factors. It's easy to make mistakes
(the current tree already contains mistakes), and there's not much
benefit.

To avoid all of this, just always define osi_timeval32_t to be our own
struct with afs_int32 fields, and provide definitions for osi_GetTime
that convert from the native time struct to our osi_timeval32_t. This
does mean that for some platforms we do an unnecessary type
conversion, but this is a small price to pay for more straightforward
and maintainable code.

To be a little more sure that our types are correct, change
osi_GetTime to be defined as an inline function instead of a macro.

At the same time, do a similar conversion for the KERNEL
implementation of the rx clock_GetTime function. Get rid of
platform-specific mess, and do a straightforward type conversion
between osi_timeval32_t and struct clock in an inline function.

a5c3dfe99f afs: Move osi_GetTime out of param.h
Most platforms currently #define osi_GetTime in their param.h. This is
really redundant, since the definition of osi_GetTime almost never
changes for a given platform, so we end up with many copies of the
same osi_GetTime definition for a given platform.

Move osi_GetTime out of param.h for these platforms, and define it in
osi_machdep.h instead, which is where most platform-specific
definitions go.

For DFBSD, we don't have an osi_machdep.h at all yet, so create a new
one to contain the osi_GetTime definition. Currently we don't build
libafs at all on DFBSD, but do this anyway so we don't lose the
existing osi_GetTime definition.

For NBSD, we were providing (conflicting!) definitions for osi_GetTime
in param.h and in osi_machdep.h. Just remove the definitions in
param.h, since those should have been getting overridden by the
osi_machdep.h definition.

c56873bf95 afs: Avoid using logical OR when setting f_fsid
Building with clang-10 produces the warning/error message
    warning: converting the result of '<<' to a boolean always evaluates
    to true [-Wtautological-constant-compare]
for the expression
    abp->f_fsid = (AFS_VFSMAGIC << 16) || AFS_VFSFSID;

The message is because a logical OR '||' is used instead of a bitwise
OR '|'.  The result of this expression will always set the f_fsid
member to a 1 and not the intended value of AFS_VFSMAGIC combined with
AFS_VFSFSID.

Update the expression to use a bitwise OR instead of the logical OR.

Note: This will change value stored in the f_fsid that is returned from
statfs.

Using a logical OR has existed since OpenAFS 1.0 for hpux/solaris and in
UKERNEL since OpenAFS 1.5 with the commit 'UKERNEL: add uafs_statvfs'
b822971a.

446457a124 afs: Set AFS_VFSFSID to a numerical value
Currently when UKERNEL is defined, AFS_VFSFSID is always set to
AFS_MOUNT_AFS, which is a string for many platforms for UKERNEL.

Update src/afs/afs.h to insure that the define for AFS_VFSFSID is a
numeric value when building UKERNEL.

Clean up the preprocessor indentation in src/afs/afs.h in the area
around the AFS_VFSFSID defines.

Thanks to adeason@sinenomine.net for pointing out a much easier solution
for resolving this problem.

e5f44f6e9a clang-10: ignore fallthrough warning in generated code
Clang-10 will not recognize '/* fall through */' as an indicator to
turn off the fallthrough warning due to the lack of a 'break' in a case
statement.

Code generated by flex uses the '/* fall through */' comments to turn
off compiler warnings for fallthroughs in case statements.

For code generated by flex, ignore the implicit-fallthrough via pragma
or disable the warning via a compile time flag.

Add new env variable "CFLAGS_NOIMPLICIT_FALLTHROUGH" to selectively
disable the compile check in Makefiles when checking is enabled.

16f1b2f894 clang-10: use AFS_FALLTHROUGH for case fallthrough
Clang-10 will not recognize '/* fallthrough */' as an indicator to
turn off the fallthrough diagnostic due to the lack of a 'break' in a
case statement.  Clang-10 requires the '__attribute__((fallthrough))'
statement to disable the diagnostic.

In addition clang-10 is finding additional locations where fall throughs
occur.

Determine if the compiler supports '__attribute__((fallthrough))' to
disable the implicit fallthrough diagnostic.

Define a new macro 'AFS_FALLTHROUGH' that will disable the fallthrough
diagnostic. Set it as a wrapper for the Linux kernel's 'fallthrough'
macro if available, otherwise set it as a wrapper macro for
'__attribute__((fallthrough))' if the compiler supports it.

Update CODING to document the use of AFS_FALLTHROUGH when needing to
fallthrough between case statements.

Replace the '/* fallthrough */' comments with AFS_FALLTHROUGH, and add
AFS_FALLTHROUGH as needed.

Replace some fallthroughs with a break (or goto) if the flow was was
just to a break (or goto).

e.g.   case x:                 case x:
           somestmt;               somestmt;
                                   break;
       case y:                 case y:
           break;                  break;

Correct a mis-indented brace '}' in src/WINNT/afsd/smb3.c

Note, the clang maintainers have rejected the use of comments as a flag
to turn off the fall through warnings.

e61ab9353e redhat: Add make to the dkms-openafs pre-requirements
If `make` is not installed before dkms-openafs, the OpenAFS kernel
module is not built during the dkms-openafs package installation.

The failure happens in the "checking if linux kernel module build works"
configure step, which invokes `make` to check the linux buildsystem.
configure fails when `make` is not available, and gives the unhelpful
suggestion (in this case) of configuring with --disable-kernel module.

Running the configure.log in the dkms build directory shows:

    configure:7739: checking if linux kernel module build works
    make -C /lib/modules/4.18.0-193.6.3.el8_2.x86_64/build M=/var/lib/dkms/openafs/...
    ./configure: line 7771: make: command not found
    configure: failed using Makefile:

Avoid this build failure by adding `make` to the list of dkms-openafs
package pre-requirements.
