Linux: Remove extra "goto out" from tmpfs fix

Remove a stray "goto out" that should not have been applied in
this spot along with the tmpfs fix.

Thanks to Stephan Wiesand for pointing it out.

Linux: Fix tmpfs cache support

As of kernel 3.1, tmpfs no longer has a readpage() operation in its
address space operations. Some of the cache manager code relies on
this, causing an oops if tmpfs is used as backing store for the
cache.

As a minimal fix, detect that there is no readpage() and disable
the optimizations that depend on it.

Linux: stop trying to use getname/putname

The current code has afs_putname defined as

kmem_cache_free (names_cachep, (void *) name);

This is wrong and will cause a double -free when syscall auditing is
enabled. Fix it to call putname properly.

Instead of that, just create a new afs_getname function that doesn't
bother with struct filename at all, and use that unconditionally.

Fix DARWIN build with clang

In 1d8937b86050 we added a function call to kauth_cred_unref in the
DARWIN100 case (replacing a macro), but added the inclusion of
sys/kauth.h only when using versions older than DARWIN80.
On DARWIN100 and above, clang detects that the now-implicit function
declaration is in conflict with the actual prototype, which is included
later through afs/sysincludes.h when compiling the kernel rx code.

Since including sys/kauth.h seems to have been harmless for old versions,
just include it always.

DARWIN: Make crfree() an inline function

On Darwin 100, we have
#define crfree(X) kauth_cred_unref(&X)
which expands in one place to
kauth_cred_unref(&(afs_ucred_t *)avc->linkData)

clang warns about this in -Werror mode, because arguments to the
address-of operator must be lvalues.

To fix this make crfree an inline function, which will then let us do
the indirection required.

Support for changes to OS X Mavericks VNOP_SYMLINK() function.

Add support for an extra argument to afs_symlink() to return the
newly-created symlink vnode if requested (this is needed on OS X
Mavericks). On OS X Mavericks return the newly-created symlink vnode in
the symlink vnops functions, on all other platforms ignore it.

It turns out that technically OS X has required the symlink to be
created for a while, but code inside of symlink() would call namei() on
the symlink name if the returned vnode point was NULL. The difference
is that on Mavericks the Manditory Access Control Framework has been
enabled, and that turns on some extra code which unconditionally calls
vnode_mount() on the returned vnode pointer, which ends up causing a
panic

rx: Always call rxi_StartListener

Commit c10f5296 made rx_Init only call rxi_StartListener in the kernel
if we have RXK_LISTENER_ENV. But this doesn't make any sense, since
rxi_StartListener only does anything if RXK_LISTENER_ENV is _not_
defined. As a result, for any non-rxk-listener non-rx-upcall platform,
we never receives rx packets in the kernel, since we never set up our
rx packet callback. The only such platform appears to be AIX, since
while other platforms (HPUX, FBSD, IRIX) have a non-rxk-listener mode,
they also implement an rxk-listener mode that we always turn on.

So, just always call rxi_StartListener, and let the ifdef guards for
the various implementations of rxi_StartListener do the right thing.

Linux 3.11: Convert from readdir to iterate file operation

Convert the readdir function so that it can be used as the new
"iterate" file operation. This new operation is passed a context
that contains a pointer to the filldir function and the offset.
The context is passed into the new dir_emit function that will
call the function specified by the context.

The new dir_emit function returns true on success, so we must be
careful about how we check for failure since this is different
behaviour from what filldir currently does.

Add support for deriving DES keys to klog.krb5

Reload rxkad.keytab on CellServDB modification

Make the reloading of rxkad.keytab keys occur in the same way that
KeyFile keys are reloaded. That is, we only try to reload them if the
CellServDB mtime has changed. This is intended to have exactly the
same reloading behavior as KeyFile reloads.

I would have triggered this from afsconf_Check, but that approach
has annoyances. (Calling ticket5_keytab functions directly from
cellconfig pulls in libkrb5 dependencies for everything that uses
cellconfig, and we'd have to trigger an afsconf_Check call by calling
some other cellconfig function.)

Avoid calling afsconf_GetLatestKey directly

Don't call afsconf_GetLatestKey to determine whether we can print our
own local tokens, since we may have keytab 'local' keys, but no DES
keys. Just try to construct them and see if it fails, using
afsconf_PickClientSecObj or afsconf_ClientAuth{,Secure} as
appropriate.

auth: Do not always fallback to noauth

Make afsconf_PickClientSecObj error out if we can't construct
localauth tokens (unless the caller explicitly requested rxnull
fallback). afsconf_ClientAuth{,Secure} still falls back, as always.

Clean up akimpersonate and use for server-to-server

Since a6d7cacfd, aklog has been able to print a krb5 ticket to
itself for an arbitrary client principal, allowing a user with
access to the cell's krb5 key to get tokens as an arbitrary user.

Now that it is possible to use native krb5 tickets with non-DES
enctypes for authentication, and akimpersonate is available from libauth,
use printed native krb5 tickets for server-to-server communication (as well
as the -localauth versions of the client utilities).

Remove the early call to afsconf_GetLatestKey() in
afsconf_PickClientSecObj() so that we do not end up picking an old DES
key before we try to find a better key to use.

Before doing so, refactor the akimpersonate code to be more usable
and readable, and eliminate some dead code.  For example, we always printed
addressless tickets, so that code could be removed.  Other code had excessive
stack usage for a library routine, which is eliminated.  Use a start time
of 0 instead of 300 so that the printed ticket will always be
detected as infinite-lifetime.

In order to ensure usability on all platforms (in particular Solaris),
provide a couple more compat shims to implement routines which are not
always available from the krb5 library, in particular encode_krb5_ticket
and encode_krb5_enc_tkt_part.  Thanks to Andrew Deason for implementing
these compatability routines.

UKERNEL doesn't need this stuff.

Move akimpersonate to libauth

Give it its own source file and header, install the header at
depinstall time, and have aklog get the akimpersonate functionality
from libauth.

Keep the linux box copyright from aklog_main.c (but strip the trailing
whitespace), as that block was added with the akimpersonate code.

Remove all calls to afs_com_err() as is fitting for library code,
to let it build. Do not bother removing curly braces which are
no longer needed; a future cleanup commit will catch that.

Derive DES/fcrypt session key from other key types

If a kerberos 5 ticket has a session key with a non-DES enctype,
use the NIST SP800-108 KDF in counter mode with HMAC_MD5 as the PRF to
construct a DES key to be used by rxkad.

To satisfy the requirements of the KDF, DES3 keys are first compressed into a
168 bit form by reversing the RFC3961 random-to-key algorithm

Add rxkad server hook function to decrypt more types of tokens

Allow tokens to be encrypted with algorithms other than DES.
The security object owner must provide an implementation
by calling rxkad_SetAltDecryptProc.

Make sure plainsiz is initialized before calling the alternate decrypt
proc.

viced: Rename fs_rxstat_userok

The fs_rxstat_userok function can be used for other purposes; give it

OpenBSD 5.3: Replace use of copyinstr for setting mount point name.

As a result of a realignment of kernel memory in OpenBSD 5.3,
the copyinstr() routine no longer works for copying the mount
point name into the internal mount table structure. It also
fails silently, so it's not noticed until someone looks at
the mount table and discovers that the mount point name for
AFS is missing.

This patch replaces the use of copyinstr() with strlcpy() for

Note that this is consistent with how other similar device

afs: Do not invalidate all dcaches on startup

Commit 20b0c65a289e2b55fb6922c8f60e873f1f4c6f97 changed
afs_UFSGetDSlot to always treat a dslot entry as invalid if
'datavalid' was 0. This was to force the invalidation of the given
dslot if we were reading in a dslot from the free or discard list,
since the data in that dslot is not valid.

However, 'datavalid' is also 0 when we read in dcache entries from
disk on startup. So, this means that we invalidated all cache entries
when the client started up, effectively making our persistent cache
worthless.

Fix this by only forcing this invalidation when we are reading from a
free or discarded dcache, and not during the initial cache scan. That
is, when 'indexvalid' is 1, and 'datavalid' is 0.

The parameters for these Get*DSlot variants should maybe be changed to
be a little more clear, but for now, this is a targeted fix for this
specific issue.

Make ihandle sync behavior runtime-configurable

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.

LINUX: Sometimes let dentry_open handle refcounts

When Linux changed dentry_open to use a 'path' argument, they also
changed it so dentry_open handles incrementing the relevant ref
counts. So now, sometimes we need to inc the dentry and vfsmount
refcounts ourselves, and sometimes we need to leave them alone.

To accommodate this, change afs_dentry_open to also handle refcounting
itself, and 'get' the given dentry and vfsmount if necessary.

Also note that currently, afs_linux_raw_open can call afs_dentry_open
twice in the case of an error, but it does not dget(dp). This means
that dp could be undercounted, since dentry_open on older kernels will
dec the refcount on the given dentry in the case of an error. This
change should also fix this so dp is not undercounted in that case.

ubik: Try to detect VOTE_Beacon errors

Currently the way ubik dbsites vote for each other is via the "return
value" of the Beacon VOTE RPC. Since this is really an Rx abort, this
can easily collide with actual errors on the wire, such as rxkad
errors.

Try to detect these by detecting vote times that are very different
than the current timestamp (more than an hour in the future or past),
and treat it like a network error.

If we do not do this, a single site reporting an error can cause us to
never reach quorum, since we calculate our sync site expiration based
on the oldest 'yes' vote, which for most known Rx aborts will be far
in the past.

vos: Restore some VNOVOL error messages

Many places in vos/vsprocs have code to delete a volume. Commit
f4e73067cdef990262c69c38ac98761620a63f25 tried to refactor them by
consolidating the common "delete" code into DoVolDelete. However, not
all of the removed code had exactly the same behavior, and some of
these variants were not handled by DoVolDelete.

One such variation is that DoVolDelete always printed an error message
if the target volume did not exist. But for some call sites this
condition is not an error, and prior to the refactoring they did not
print such an error message. Commit
1092cbe34fc8519826b3fa0565505b7bd81bc922 tried to correct this by
suppressing the error message if the target volume does not exist.
However, this means that all DoVolDelete calls do not print such an
error, where some should and some should not print an error. This
means that in some edge cases when we encounter an unexpected VNOVOL
error, we now skip printing the specific error we got and instead go
right to cleanup/recovery/exit. For a few other cases, we used to
print an error and continue (because it is a non-fatal error or a
warning), but now we print nothing when we encounter a VNOVOL error.

Fix this by specifically printing an error for the VNOVOL error for
DoVolDelete call sites that used to print such an error. Do this for
all such sites except ones where we obviously print an error
immediately afterwards anyway.

This is just a quick targeted fix. A future more robust fix should
involve altering DoVolDelete to handle all of the different behaviors
expected by its various callers.

With vos refactor commit f4e73067cdef990262c69c38ac98761620a63f25,
some formerly conditional volume deletes are now unconditional.
This regresses 'vos move' output with harmless "error" messages
when AFSVolTransCreate() returns VNOVOL:
"Failed to start transaction on <volume>"
"Volume not attached, does not exist, or not online"

Modify DoVolDelete() to return early (and silently) with VNOVOL
in this case, allowing the caller to handle this appropriately.

afsd: Parse cacheinfo during argument parsing

Currently we parse cacheinfo in afsd_run, when the client is
initialized and started. Parsing cacheinfo can change
afsd_cacheMountDir, however, which may be of interest to afsd.o users;
in particular, libuafs exposes this via uafs_MountDir(). This means
that if a mount dir is not explicitly specified in the libcmd
arguments to afsd, a libuafs-using program will see the mountpoint as
the empty string if it is queried after afsd_parse but before
afsd_run. For afsd.fuse, this causes the cryptic error message:

fuse: bad mount point `': No such file or directory

since the mountpoint is the empty string if it is not specified
explicitly on the command line.

To fix this, move cacheinfo parsing to effectively near the end of
afsd_parse, so the mountpoint is calculated in afsd_parse().

true under certain circumstances when evaluating mountpoints.

To fix this, populate the dnlc for non-mountpoints, even if force_eval

viced: initInterfaceAddr_r regardless of ICBS code

Currently we only call initInterfaceAddr_r for a host if a call to
RXAFS_InitCallBackState3 succeeds. However, this leaves the host
without a host->interface structure, which indicates that the host
does not support UUIDs, and is represented by just a single host,port
pair.

But this is not correct; the host probably does have the relevant UUID
associated with it, but it is just not responding. So, with the
current code, we create a uuid-less host structure for a host that
probably has a uuid; that host structure will probably never be used,
and will just get deleted later.

So instead, always call initInterfaceAdd_r. Do it before the ICBS
call, so the host will be findable via UUID as early as possible. If
the ICBS call fails, the host will be marked as 'down' later on.

- For newer kernels with aio, let the kernel use its default read

with the AFS specific bits, calling into generic_file_aio_read/write.
The kernels default read/write operations are just wrappers around the

Beautify ubik_print()

After lots of intermediate steps a call to ubik_print(), ubik_vprint()
and ubik_dprint*() ends in vFSLog() which adds a timestamp to the output.
So any call to ubik_print(), that does not contain a \n at the end,
makes a mess of the logfile.
The least invasive change will simply add this newline at the end
of any ubik_print() call.
This also prevents long lines in the log, which might appear on
multi-homed hosts with lots of interfaces.

viced: Avoid dangling uuid hash table entry

Currently we add a given host to the uuid hash table, then call
RXAFS_InitCallBackState3, and then only initialize the host->interface
structure if the ICBS3 call succeeded.

If the ICBS3 call fails, we have added a host to the uuid hash table,
but the host structure does not contain that uuid. If the host is then
deleted, we will not remove the host from the uuid hash table (since
host->interface is NULL), and so the uuid hash table entry will still
point to the freed host. If that host is then later looked up via that
uuid, we can reference a freed host, which can cause all kinds of
undefined behavior.

So instead, add the host to the uuid hash table at the same time that
we initialize the host->interface structure, inside
initInterfaceAddr_r.
