There exist in the wild AFS3 clients that improperly construct access
control lists which are then stored to directories via RXAFS_StoreACL
(opcode 134). These clients add negative access control entries (if any)
to the normal rights list.
As there is no method by which a fileserver can determine that the
ACL is improperly constructed, the only method to defend the storage of
broken ACLs is to identify clients that are known to properly construct
ACLs by introducing a new RXAFS_StoreACL opcode (164).
This change:
* Renames RXAFS opcode 134 to RXAFS_OldStoreACL
* Introduces RXAFS opcode 164 as RXAFS_StoreACL
* Implements SRXAFS_OldStoreACL and SRXAFS_StoreACL in the fileserver
via a common_StoreACL() function that accepts the executed opcode
as input.
* To avoid breaking changes in stable release branches,
SRXAFS_OldStoreACL will still be allowed by default, with an option
to cause it to be failed by default with error EPERM/UAEPERM.
A follow-up commit will cause SRXAFS_OldStoreACL to fail by default
on the master branch.
* When opcode 134 is called, the a FileLog entry will be generated
at log level 0 instead of 1 and the entry will contain the string
"CVE-2018-7168".
* Modifies the format of the ACL logged to the FileLog and the audit
stream. Previously the AFSOpaque format was used directly. The
problem with this format is that it uses newlines as the ACE
separator. Since the FileLog and file audit log is intended to
be one line per log entry, the newlines break the file formats.
This change replaces the newlines with spaces for display purposes
unless the process is unable to allocate the additional memory.
* Introduces a new fileserver command line switch -cve-2018-7168-enforce
which when specified causes SRXAFS_OldStoreACL RPCs to be failed.

Commit dfceff1d3a added the
-preserve-vol-stats flag to the volume server. This enabled a change in
the volume server to preserve volume usage statistics during reclone and
restore operations. Otherwise, volume usage counters of read-only
volumes are cleared when volumes are released, making it difficult to
track usage with the volume stats.
Make this feature the default behavior of the volume server and provide
the option -clear-vol-stats to use the old behavior if so desired. This
change makes the -preserve-vol-stats the default, and keeps it as a
hidden flag for sites which may already have that flag set in the
BosConfig.
Since this changes a default behavior of the volume server, this change
is only appropriate on a major or minor release boundary, not in the
middle of a stable series.

The ability to set the size of the volume hash table was added
at the same time that DAFS was introduced, and got caught up
in the same preprocessor conditional. However, -vhashsize can
be useful for the traditional fileserver as well (even though
we recommend DAFS over the traditional fileserver), so let it
be used in that case.
Update the man pages accordingly and fix some grammar while here.

* never -- the existing behavior
* always -- switch to using afsconf_ClientAuthSecure, which uses
rxkad_crypt, for ForwardVolume calls.
* inherit -- encrypt inter-server traffic if the causal client
connection is encrypted. This has the effect of "inheriting" the
"-encrypt" flag given to "vos release", for example.

The actual behavior of FDH_SYNC has changed a bit over the years, and
some people want one behavior, and some want another. Make it possible
to make this choice at runtime with the new -sync option, instead of
making this decision by running with different patches.
Note that FDH_SYNC is not a macro anymore, nor is it an inline
function. While it could be a macro, it would look a bit complex, and
there are some oddities with trying to use vol_io_params inside the
FDH_SYNC expansion (vol_io_params is not declared for LWP, for
example). And having it be an inline function causes problems with
some odd linking dependencies. For example, vlib.a contains volume.o,
but does not contain a definition for DFlushVolume (dir/buffer.c),
which is referenced in volume.o. 'vos' uses vlib.a, but does not
bring in anything that defines DFlushVolume. Currently this appears to
not cause a problem because 'vos' uses nothing from volume.o, so the
dependencies of volume.o don't matter. Adding an inline FDH_SYNC for
platforms that don't support 'static inline' would add a dependency to
volume.o (via vol_io_params), which causes an error for the lack of a
DFlushVolume.
Those are possibly just some problems, and may not be all. So instead,
make it so we don't have to deal with that and just have a normal
function. While FDH_SYNC may be called in a performance-critical
section, the overhead of a real function call is nowhere near the
delay of an actual fsync(), so presumably any overhead doesn't matter.
