5 years agorx: Convert rxinit_status to rx_IsRunning() 16/13416/2
Andrew Deason [Thu, 2 Nov 2017 21:41:52 +0000]
rx: Convert rxinit_status to rx_IsRunning()

Currently, all rx code examines the atomic rxinit_status to determine
if rx is running (that is, if rx_InitHost has been called, and
rx_Finalize/shutdown_rx hasn't been called). This is used in rx.c to
see if we're redundantly calling our setup/teardown functions, and
outside of rx.c in a couple of places to see if rx-related resources
have been initialized.

The usage of rxinit_status is a little confusing, since setting bit 0
indicates that rx is not running, and clearing bit 0 indicates rx is
running. Since using rxinit_status requires atomic functions, this
makes code checking or setting rxinit_status a little verbose, and it
can be hard to see what it is checking for. (For example, does
'if (!rx_atomic_test_and_clear_bit(&rxinit_status, 0))' succeed when
rx running, or when rx is not running?)

The current usage of rxinit_status in rx_InitHost also does not handle
initialization errors correctly. rx_InitHost clears rxinit_status near
the beginning of the function, but does not set rxinit_status if an
error is encountered. This means that any code that checks
rxinit_status (such as another rx_InitHost call) will think that rx
was initialized successfully, but various resources aren't actually
setup. This can cause segfaults and other errors as the code tries to
actually use rx.

This can easily be seen in bosserver, if bosserver is started up while
the local host/port is in use by someone else. bosserver will try to
rx_InitHost, which will fail, and then we'll try to rx_InitHost again,
which will immediately succeed without doing any init. We then
segfault quickly afterwards as we try to use unitialized rx resources.

To fix all of this, refactor code using rxinit_status to use a new
function, called rx_IsRunning(), to make it a little clearer what
we're checking for. We also re-introduce the LOCK_RX_INIT locks to
prevent functions like rx_InitHost and rx_Finalize from running in
parallel.

Note that non-init/shutdown code (such as rx_upcall or rx_GetIFInfo)
does not need to wait for LOCK_RX_INIT to check if rx is running or
not. These functions only care if rx is currently setup enough to be
used, so we can immediately return a 'yes' or 'no' answer. That is, if
rx_InitHost is in the middle of running, rx_IsRunning returns 0, since
some resouces may not be fully initialized.

Background:

Commit 1c96127e37c0ec41c7a30ea3e4aa68f3cc8a24f6 standardized the
location where the openafs.ko module is installed (from
/kernel/3rdparty to /extra/).  The RPM Spec file was not updated to
build the dkms.conf file with the corrected location.

From the documentation for dkms

 DEST_MODULE_LOCATION is ignored on Fedora Core 6 and higher, Red Hat
 Enterprise Linux 5 and higher, Novell SuSE Linux Enterprise Server 10
 and higher, Novell SuSE Linux 10.0 and higher, and Ubuntu.  Instead,
 the proper distribution-specific directory is used.

However the DEST_MODULE_LOCATION is still used saving and restoring old
copies of the module.

The NO_WEAK_MODULES parameter prevents dkms from creating a symlink into
weak-updates directory, which can lead to broken symlinks when
dkms-openafs is removed.  The weak modules facility was designed to
eliminate the need to rebuild kernel modules when kernel upgrades occur
and relies on the symbols within the kABI.  Openafs uses symbols that
are outside the kABI, and therefor is not a candidate for a weak module.

5 years agorx: reset packet header userStatus field on reuse 32/13332/4
Jeffrey Altman [Thu, 7 Jun 2018 01:23:14 +0000]
rx: reset packet header userStatus field on reuse

OpenAFS Rx fails to set the rx packet header userStatus field for most
packets sent other than type RX_PACKET_TYPE_ACK.  If the userStatus
field is not set, its value will be random garbage based upon the
prior use of the memory allocated to the rx_packet.

This change explicitly sets the userStatus field to zero for all
DATA and Special packet types.

Background
----------

OpenAFS Rx allocates a pool of rx_packet structures that are reused
for both incoming and outgoing Rx packets throughout the lifetime
of the process (or kernel module).

The rx packet header field userStatus is set by rxi_Send() to
rx_call.localStatus.  rxi_Send() is called from both rxi_SendAck()
when sending RX_PACKET_TYPE_ACK packets and from rxi_SendSpecial()
when called with a non-NULL call structure (RX_PACKET_TYPE_BUSY,
RX_PACKET_TYPE_ACKALL, or RX_PACKET_TYPE_ABORT).  rx_call.localStatus
defaults to zero and can be modified by the application calling
rx_SetLocalStatus().

The userStatus field is neither set nor reset when sending
RX_PACKET_TYPE_DATA packets and all packets sent without a call
structure.  When allocated packets are reused in these cases, the
value of the userStatus leaks from the prior packet use.  The
userStatus field is expected to be zero unless intentionally set by
the application protocol to another value.

The AFS3 suite of rx services uses the rx_header.userStatus field
only in the RXAFS service and only as part of the definition
for RXAFS_StoreData and RXAFS_StoreData64 RPCs.  The StoreData RPCs
use the rx_header.userStatus field as an out-of-band communication
mechanism that permits the fileserver to signal to the cache manager
when the RXAFS_StoreData[64] has been assigned to an application
worker (thread) and the worker has acquired all of the required locks
and other resources necessary to complete the RPC.  This signal can be
sent before all of the application data has been received.  The cache
manager reads the userStatus value via rx_GetRemoteStatus().  When
bit-0 of the remote status value equals one and CSafeStore mode is
disabled, the cache manager can wakeup any threads blocked waiting for
the store operation to complete.

Cache managers that perform a workload heavy in RXAFS_StoreData[64] RPCs
will end up with an increasing percentage of packets in which the
userStatus field is one instead of zero.

Fileservers processing a workload heavy in RXAFS_StoreData[64] RPCs
will likewise end up with an increasing percentage of packets in which
the userStatus field is one instead of zero.

Cache managers and Fileservers will therefore send DATA and call free
special packets with a non-zero userStatus field to peer services
(RXAFS, RXAFSCB, VL, PR).

The failure to reset the userStatus field has not been a problem in
the past because only the OpenAFS cache manager has ever queried the
userStatus via rx_GetRemoteStatus() and only when issuing
RXAFS_StoreData[64] RPCs.

Failure to correct this flaw interferes with future use of the userStatus
field in yet to be registered AFS3 RPCs and existing non-AFS3 services
that make use of the userStatus when sending data to a service.

5 years agovolser: ensure GCTrans transaction walk remains valid 37/13337/3
Mark Vitale [Fri, 17 Aug 2018 22:48:08 +0000]
volser: ensure GCTrans transaction walk remains valid

Commit bc56f5cc97a982ee29219e6f258b372dbfe1a020 ("volser: Delete
timed-out temporary volumes") introduced new logic to GCTrans().
Unfortunately, part of this logic temporarily drops VTRANS_LOCK in order
to call VPurgeVolume().  While this lock is dropped, other volser_trans
may be added or deleted from the allTrans list.  Therefore, GCTrans
should not trust the next pointer (nt = tt->next) which was obtained
before the lock was dropped.

One symptom observed in the field was a segfault while examining
tt->volume.  Neither tt nor volume were valid any longer, since tt had
been set from a stale nt at the top of the loop.

To repair, improve, and clarify this logic:
- Refactor so nt is assigned correctly and as late as possible.
- Add comments to explain the placement of the assigns to future
maintainers.

5 years agoafs: Return memcache allocation errors 07/13307/5
Andrew Deason [Tue, 7 Aug 2018 22:08:26 +0000]
afs: Return memcache allocation errors

During cache initialization, we can fail to allocate our dcache
entries for memcache. Currently when this happens, we just log a
message and try to disable dcache access. However, this results in at
least one code path that causes a panic anyway during startup, since
afs_CacheTruncateDaemon will try to trim the cache, and afs_GetDownD
will call afs_MemGetDSlot, and we cannot find the given dslot.

To avoid this, change our cache initialization to return an error,
instead of trying to continue without a functional dcache. This causes
afs_dcacheInit to return an error in this case, and by extension
afs_CacheInit and the AFSOP_CACHEINIT syscall. Also change afsd to
actually detect errors from AFSOP_CACHEINIT, and to bail out when it
does.

Thanks to gsgatlin@ncsu.edu for reporting the relevant panic.

5 years agoubik: Buffer log writes with stdio 53/13353/5
Andrew Deason [Thu, 10 May 2018 21:22:52 +0000]
ubik: Buffer log writes with stdio

Currently, when we write ubik i/o operations to the db log, we tend to
issue several syscalls involving small writes and fstat()s. This is
because each "log" operation involves at least one write, and each log
operation tends to be pretty small.

Each logged operation hitting disk separately is unnecessary, since
the db log does not need to hit the disk at all until we are ready to
commit the transaction. So to reduce the number of syscalls when
writing to the db, change our log writes to be buffered in memory
(using stdio calls). This also avoids needing to fstat() the
underlying log file, since we open the underlying file in append-only
mode, since we only ever append to (and truncate) the log file.

To implement this, we introduce a new 'buffered_append' phys
operation, to explicitly separate our buffered and non-buffered
operations, to try to avoid any bugs from mixing buffered and
non-buffered i/o. This new operation is only used for the db log.

ubik: do not assign variables in logging argument lists

within the logging function call argument list, which would set a
variable as side effect of evaluating the function call arguments.

These embedded assignments are problematic since the logging function
calls have been replaced by ViceLog macros, which avoid the overhead of
a function call depending on logging levels.

Remove the embedded assignments within the logging argument lists so the

OPENAFS-SA-2018-001 backup: use authenticated connection to butc

Use the standard routine to pick a client security object, instead of
always assuming rxnull.  Respect -localauth as well as being able to
use the current user's tokens, but also provide a -nobutcauth argument
to fall back to the historical rxnull behavior (but only for the connections
to butc; vldb and budb connections are not affected).

OPENAFS-SA-2018-001 butc: require authenticated connections with -localauth

The butc -localauth option is available to use the cell-wide key to
authenticate to the vlserver and buserver, which in normal deployments
will require incoming connections to be authenticated as a superuser.
In such cases, the cell-wide key is also available for use in
authenticating incoming connections to the butc, which would otherwise
have been completely unauthenticated.

Because of the security hazards of allowing unauthenticaed inbound
RPCs, especially ones that manipulate backup information and are allowed
to initiate outboud RPCs authenticated as the superuser, default to
not allowing unauthenticated inbound RPCs at all.  Provide an opt-out
command-line argument for deployments that require this functionality
and have configured their network environment (firewall/etc.) appropriately.

OPENAFS-SA-2018-003 rxgen: prevent unbounded input arrays

RPCs with unbounded arrays as inputs are susceptible to remote
denial-of-service (DOS) attacks.  A malicious client may submit an RPC
request with an arbitrarily large array, forcing the server to expend
large amounts of network bandwidth, cpu cycles, and heap memory to
unmarshal the input.

Instead, issue an error message and stop rxgen when it detects an RPC
defined with an unbounded input array.  Thus we will detect the problem
at build time and prevent any future unbounded input arrays.

OPENAFS-SA-2018-003 volser: prevent unbounded input to various AFSVol* RPCs

Several AFSVol* RPCs are defined with an unbounded XDR "string" as
input.

RPCs with unbounded arrays as inputs are susceptible to remote
denial-of-service (DOS) attacks.  A malicious client may submit an
AFSVol* request with an arbitrarily large string, forcing the volserver
to expend large amounts of network bandwidth, cpu cycles, and heap
memory to unmarshal the input.

Instead, give each input "string" an appropriate size.
Volume names are inherently capped to 32 octets (including trailing NUL)
by the protocol, but there is less clearly a hard limit on partition names.
The Vol_PartitionInfo{,64} functions accept a partition name as input and
also return a partition name in the output structure; the output values
have wire-protocol limits, so larger values could not be retrieved by clients,
but for denial-of-service purposes, a more generic PATH_MAX-like value seems
appropriate.  We have several varying sources of such a limit in the tree, but
pick 4k as the least-restrictive.

OPENAFS-SA-2018-003 volser: prevent unbounded input to AFSVolForwardMultiple

AFSVolForwardMultiple is defined with an input parameter that is defined
to XDR as an unbounded array of replica structs:
  typedef replica manyDests<>;

RPCs with unbounded arrays as inputs are susceptible to remote

Even though AFSVolForwardMultiple requires superuser authorization, this
attack is exploitable by non-authorized actors because XDR unmarshalling
happens long before any authorization checks can occur.

Add a bounding constant (NMAXNSERVERS 13) to the manyDests input array.
This constant is derived from the current OpenAFS vldb implementation, which
is limited to 13 replica sites for a given volume by the layout (size) of the
serverNumber, serverPartition, and serverFlags fields.

OPENAFS-SA-2018-003 budb: prevent unbounded input to BUDB_SaveText

BUDB_SaveText is defined with an input parameter that is defined to XDR
as an unbounded array of chars:
   typedef char charListT<>;

RPCs with unbounded arrays as inputs are susceptible to remote
denial-of-service (DOS) attacks.  A malicious client may submit a
BUDB_SaveText request with an arbitrarily large array, forcing the budb
server to expend large amounts of network bandwidth, cpu cycles, and
heap memory to unmarshal the input.

Modify the XDR definition of charListT so it is bounded.  This typedef
is shared (as an OUT parameter) by BUDB_GetText and BUDB_DumpDB, but
fortunately all in-tree callers of the client routines specify the same
maximum length of 1024.

Note: However, SBUDB_SaveText server implementation seems to allow for up to
BLOCK_DATA_SIZE (2040) = BLOCKSIZE (2048) - sizeof(struct blockHeader)
(8), and it's unknown if any out-of-tree callers exist.  Since we do not need a
tight bound in order to avoid the DoS, use a somewhat higher maximum of
4096 bytes to leave a safety margin.

OPENAFS-SA-2018-003 vlserver: prevent unbounded input to VL_RegisterAddrs

VL_RegisterAddrs is defined with an input argument of type bulkaddrs,
which is defined to XDR as an unbounded array of afs_uint32 (IPv4 addresses):
  typedef afs_uint32 bulkaddrs<>

The <> with no value instructs rxgen to build client and server stubs
that allow for a maximum size of "~0u" or 0xFFFFFFFF.

Ostensibly the bulkaddrs array is unbounded to allow it to be shared
among VL_RegisterAddrs, VL_GetAddrs, and VL_GetAddrsU.  The VL_GetAddrs*
RPCs use bulkaddrs as an output array with a maximum size of MAXSERVERID
(254). VL_RegisterAddrss uses bulkaddrs as an input array, with a
nominal size of VL_MAXIPADDRS_PERMH (16).

However, RPCs with unbounded array inputs are susceptible to remote
denial-of-service attacks.  That is, a malicious client may send a
VL_RegisterAddrs request with an arbitrarily long array, forcing the
vlserver to expend large amounts of network bandwidth, cpu cycles, and
heap memory to unmarshal the argument.  Even though VL_RegisterAddrs
requires superuser authorization, this attack is exploitable by
non-authorized actors because XDR unmarshalling happens long before any
authorization checks can occur.

Because all uses of the type that our implementation support have fixed
bounds on valid data (whether input or output), apply an arbitrary
implementation limit (larger than any valid structure would be), to
prevent this class of attacks in the XDR decoder.

[kaduk@mit.edu: limit the bulkaddrs type instead of introducing a new type]

current_kernel_time() returns the 32-bit struct timespec.
current_kernel_time64() returns the 64-bit struct timespec64.

redhat: actually remove unused AFS::ukernel man page

Commit 278581c24a802834719e0d57f27978321556c9bb (redhat: package libuafs
perl bindings) added swig as a build dependency on RHEL 6+/Fedora 15+ to
build and package AFS::ukernel perl bindings for libuafs.  The man page
for AFS::ukernel is generated from the pod files unconditionally, so
needs to be removed from the staging directories when AFS::ukernel is
not packaged.

Unfortunately, the full path to the staged AFS::ukernel manpage was
not given in that commit, so the rpmbuild will fail on RHEL 5 with
the error:

        RPM build errors:
        Installed (but unpackaged) file(s) found:
        /usr/share/man/man3/AFS::ukernel.3.gz

Fix this error by specifying the full path to the AFS::ukernel man page
to actually remove it when we are not packaging AFS::ukernel files.

5 years agoafs: Stop looking for dcaches on Get*DSlot errors 91/13191/2
Andrew Deason [Thu, 26 Apr 2018 17:27:12 +0000]
afs: Stop looking for dcaches on Get*DSlot errors

In various places in the code, we'll be looking for a dslot, calling
afs_GetValidDSlot (or afs_GetUnusedDSlot) in a loop. In a few places,
we currently keep looking for the dslot when we get an error back,
since afs_GetValidDSlot may return successfully for other slots, and
we might find the dslot we're looking for.

This behavior was introduced in a few commits, including:

- commit 2679af76 (afs: Traverse discard/free dslot list if errors)
- commit 00fd34a6 (afs: Handle easy GetValidDSlot errors)
- commit 9a558660 (afs: Cope with afs_GetValidDSlot errors)

This behavior means that if afs_GetValidDSlot/afs_GetUnusedDSlot
returns an error for a particular dcache slot, but other slots are
okay, then we may still find the dcache we're looking for.

However, by far the most common reason that
afs_GetValidDSlot/afs_GetUnusedDSlot fails is because our disk cache
is completely unusable; it is very rare that only a few slots cannot
be used, but others are fine (this would mean that the disk cache was
corrupted in oddly specific ways, or there are small isolated errors
in the underlying disk). So continuing the dcache search in these
situations is not very useful.

On Linux, this is most commonly seen by the underlying disk cache i/o
calls returning -EINTR, which can happen if a SIGKILL signal is
pending for the current process when we try to do the i/o. In this
situation, all attempts to read in a dslot from disk will fail; trying
other slots or waiting will not improve the situation. Depending on
which specific code path encounters an afs_Get*DSlot error, we can
then flood the log with "disk cache read error in CacheItems" messages
emitted from afs_UFSGetDSlot, since we keep calling afs_Get*DSlot in
our loop.

The worst offender of this is usually afs_GetDSlotFromList via
afs_AllocDCache, since we end up calling afs_GetUnusedDSlot for every
single dslot in the free and discard lists. However, our other call
sites that are looking for dcaches for a specific file can still
generate quite a few of these messages, since we'll end up calling
afs_GetValidDSlot for every slot in a dcache hash chain.

So to avoid flooding the log in these situations, change most callers
of afs_GetValidDSlot and afs_GetUnusedDSlot to stop on the first
error, and act like we never found a dcache that we were looking for.

This commit also adjusts one caller in afs_ProcessOpCreate, which was
not handling errors from afs_GetValidDSlot at all, and changes
FlushVolumeData to be able to return error codes.

our free() abstractions that can run in the kernel (like afs_osi_Free,

5 years agoLINUX: Detect NULL page during write_begin 43/13243/2
Andrew Deason [Thu, 5 Jul 2018 22:16:48 +0000]
LINUX: Detect NULL page during write_begin

In afs_linux_write_begin, we call grab_cache_page_write_begin to get a
page to use for writing data when servicing a write into AFS. Under
low-memory conditions, this can return NULL if Linux cannot find a
free page to use. Currently, we always try to reference the page
returned, and so this causes a BUG.

To avoid this, check if grab_cache_page_write_begin returns NULL, and
just return -ENOMEM, like other callers of grab_cache_page_write_begin
do.

Linux's fault injection framework is useful for testing code paths
like these. The following settings made it possible to
somewhat-reliably exercise the relevant code path on a test RHEL7
system:

reported when the vldb contained more than one mh extent blocks.  That

byte order of all the mh blocks, not just the first block, in order to
check the value of those flags.

Unfortunately, that commit missed converting non-zero blocks back to
network byte order in the complementary writeMH() function, which is
used to write the data back to disk when vldb_check is run with the -fix

5 years agorxevent: prevent negative rx_connection refCount 29/13229/2
Mark Vitale [Sat, 30 Jun 2018 21:35:09 +0000]
rxevent: prevent negative rx_connection refCount

rxi_ChallengeEvent is called directly from rxi_ChallengeOn to start the
first challenge; subsequent calls to rxi_ChallengeEvent are from the
event handler.  When called as an event, we must putConnection the
reference held by the event.  But when called directly for the first
time, the event has not been scheduled yet and so has not taken a
reference on the connection.  For this case, we must not putConnection
or the rx_connection refCount will go negative.

One reported symptom of this bug is a fileserver crash with:
  'Assertion failed! file rx.c, line 1327.'

Introduced by commit 304d758983b499dc568d6ca57b6e92df24b69de8
('Standardize rx_event usage').

5 years agoafs: Avoid GetDCache delays on screwy cache 90/13190/2
Andrew Deason [Thu, 26 Apr 2018 17:01:57 +0000]
afs: Avoid GetDCache delays on screwy cache

Currently, if our afs_AllocDCache call fails in afs_GetDCache, we
retry once per second for 5 minutes. The reasoning is that we're out
of dcache slots, and so if we wait a little while, maybe something
will become freeable and we can continue.

However, afs_AllocDCache can also fail if we have plenty of free
dslots, but we are unable to successfully call afs_GetUnusedDSlot() on
any of them. This can happen if our disk cache is screwed up, and so
waiting and retrying will not make things better (but we'll spew a ton
of "disk cache read error in CacheItems slot" errors in the log each
time, and do so 300 times).

So instead, only do our sleep/retry loop if we actually appear to be
out of free or discarded dslots. Otherwise, just return an error
immediately, since sleeping and retrying will not make anything
better.

5 years agoafs: Avoid GetDCache panic on AllocDCache failure 89/13189/2
Andrew Deason [Thu, 26 Apr 2018 17:02:18 +0000]
afs: Avoid GetDCache panic on AllocDCache failure

Currently, in afs_GetDCache, if afs_AllocDCache fails, we retry for 5
minutes and then panic. Panicing in this situation is completely
unnecessary; afs_GetDCache can fail for a variety of other mundane
reasons (such as, if we can't fetch the requested data from the
relevant fileserver).

It may seem unusual for afs_AllocDCache to fail for over 5 minutes
(this is supposed to mean that we're out of dslots, and our attempts
to free up dslots have failed). However, afs_AllocDCache can also fail
if we are having issues in accessing the disk cache, and so we may not
be out of cache space or dslots at all; we just can't access the
cache. In this case, afs_AllocDCache can easily fail forever; waiting
longer or trying to free up cache space isn't going to help.

So, to avoid panicing in such situations, just make afs_GetDCache
return an error. We just need to make sure afs_xdcache is unlocked,
and then we can just jump to 'done', like plenty of other codepaths
do; no extra cleanup is required.

Also since we are removing a panic, add a log message when this
situation happens, so EIO errors don't suddenly pop up silently.

5 years agoxdr: avoid xdr_enum memory overrun 83/13183/2
Mark Vitale [Wed, 6 Jun 2018 19:23:26 +0000]
xdr: avoid xdr_enum memory overrun

Since openafs-ibm-1_0, xdr_enum has used xdr_long to read and write, even
though enum_t is defined as int.  For systems where sizeof(int) ==
sizeof(long), this works by accident.  But other systems (e.g., DARWIN
ARCHFLAGS=x86_64) xdr_enum will overrun its int-sized second parameter.  For
XDR_DECODE, this results in memory corruption.

This was first noticed with OpenAFS 1.8.0 on macOS 10.13; if aklog is issued
while already holding a token, it will fail in token_SetsEquivalent with a
segfault in decodeToken.  The root cause is that the address passed to
decodeToken had been overwritten by a previous call to tokenType -> xdr_enum ->
xdr_long.

Instead, modify xdr_enum to use xdr_int for its work.

5 years agoutil: check for trailing characters in partition names 21/13121/2
Michael Meffie [Sat, 28 Apr 2018 03:08:34 +0000]
util: check for trailing characters in partition names

The function which maps partition names to partition ids currently
ignores trailing characters in the partition names. For example, the
partition name "/vicepbogus" is currently considered a valid partition
name ("/vicepbogus" maps to "bo" which is id 66). Although this is not a
regression, it is problematic for several reasons.

Firstly, this can lead to duplicate partition ids on the server, for
example "/vicepbad" and "/vicepbar" both map to the same partition id
("ba" is id 52).

Second, partitions are internally tracked by numeric id. The partition
names are generated from numeric ids when reporting partition names.
This means the trailing characters are lost when reporting the partition
names. For example, vos reports the attached partition "/vicepbad" as
"/vicepba".

Third, it could be possible (but perhaps unlikely) in the future to
extend the range of partition ids, so the trailing characters could
become significant at that time.

Finally, it could be confusing to admins that such partition names are
attached by the fileserver. For example, "/vicepaa-backup" is attached
and is used by the fileserver as partition id 26.

This change adds a check for trailing characters in partition names in
the volutil_GetPartitionID function, so it is more strict in what it
accepts as a valid partition name.  That function will now return -1
(illegal partition name) when trailing characters are found in
partition names.

libafsauthent: export additional xdr_ functions

Formally, we need to use xdr_free to deallocate storage for RPC output
variables, in case the XDR stack uses a different allocator than the
standard application allocator.  Some types have non-autogenerated
wrappers exposed already (e.g., token_FreeSet()), but for a handful of
the base ptint types we need to expose the xdr routines in order for a
safe way to deallocate their storage to be available.

Windows: define AFS_IHANDLE_PIO_ENV for ihandle pio

Support for positional i/o in the ihandle package was added to the
windows platform in commit 50b6a116a1c412d0e6d7442d13d6e92c9dbb35ee
using native windows functions.  That commit also defined HAVE_PIO in
the windows version of the afsconfig.h file. Unfortunately, that
definition of HAVE_PIO is not limited to the ihandle package.

Remove the project-wide HAVE_PIO definition from the windows afsconfig.h
file and define the new AFS_IHANDLE_PIO_ENV symbol when position i/o
support is available in the ihandle package.

Build the fallback ih_pread and ih_pwrite functions (which use lseek)
only when positional i/o is not available in the ihandle package for the
current platform.

Use AFS_IHANDLE_PIO_ENV instead of HAVE_PIO in ih_open() to determine
when it is is safe to share ihandles among threads.

vol: check for bad partition names

Examples of such misnamed partitions are "/vicepzz", "/vicep0", and
others.

The presence of these misnamed partitions cause the server processes to
crash on startup, since the out of range partition ids are used as an
index.

Add a check for the bad partition names in VCheckPartitions to avoid
attaching them. Log a warning for such partitions to let the admins know
why the partitions are not attached.

5 years agoubik: clones should not request votes 16/13116/2
Marcio Barbosa [Tue, 15 May 2018 21:10:45 +0000]
ubik: clones should not request votes

Clones should not be able to become the sync-site. To make it possible,
regular sites do not vote for a site tagged as clone. In other words,
the clones ask for votes but they cannot be the sync-site. Knowing that
their requests for votes should be refused by the regular sites, they
should never have enough votes to win the election.

In addition to the unnecessary network traffic created by these
unnecessary requests, this current approach can be problematic in some
specific situations. As an example, consider the following scenario:

    The user wants to turn a regular site, called host1, into a clone.
    To do so, he runs the following commands on every single server:

    $ bos removehost -server <server> -host host1
    $ bos addhost -server <server> -host host1 -clone

After that, he restarts the servers, one by one. Depending on the delay
between the restarts, a clone can become the sync-site. This is possible
because the clones request votes from the other sites. If enough regular
sites are not aware (yet) that the request for vote came from a clone,
the clone in question can get enough votes to win the election.

To fix the problems mentioned above, do not request votes if you cannot
be the sync-site.

5 years agoUse afs_DestroyReq in afs_PrefetchNoCache() 14/13114/2
Benjamin Kaduk [Tue, 8 May 2018 23:04:21 +0000]
Use afs_DestroyReq in afs_PrefetchNoCache()

Since commit 76ad941902c650a4a716168d3cbe68f62aef109f we use afs_DestroyReq()
instead of osi_Free() directly.

Also update the UKERNEL version of the function to afs_CreateReq() properly.

FIXES 134533
