Simon Wilkinson [Sun, 10 Oct 2010 12:04:41 +0000]
rx: Don't malloc the xmit list

Building the transmit list happens in a time critical section of
code. Using malloc to allocate the list which holds the packets to
be transmitted slows down this critical section. Instead, just
allocate the space as part of the call structure.

Locking of xmitList is somewhat tricksy, as the call->lock is
dropped over calls to sendmsg(). However, the xmitList is protected
by the TQ_BUSY call flag, which prevents multiple threads from
usign the transmit queue, and hence the xmitList, simultaneously.

To prevent this and possibly other problems from happening, force a

secondsUntilDead <= idleDeadTime <= hardDeadTime, by checking these

by default.  To acheive this goal the windows openafs dirent.h is
moved from include\afs to include, references whenever possible to
openafs headers included in include\afs or include\rx are prefixed
with afs\ or rx\ as appropriate.

Some source files or directories have a broad range of interdependencies
that make separation quite challenging.  For those directories or files
the inclusion of the path is added at the smallest possible level.
At some point in the future the WINNT\afsd\ headers should be moved
from include\afs to include\WINNT and should be installed there first
and then referenced internally from that location instead of from the
WINNT\afsd directory.  That will permit further cleanup to be performed.

10 years agoUnix: Rework build system
Simon Wilkinson [Mon, 4 Oct 2010 12:49:16 +0000]
Unix: Rework build system

Rework the unix build system so that we support taking CFLAGS and
LDFLAGS from the command line, and don't replace them with our own
settings. Also, take the opportunity to bring some sanity and
consistency into our Makefiles.

The standard Makefile.config  now defines rules for LWP, pthreaded
and shared library builds. The CFLAGS settings for these are
called LWP_CFLAGS, PTH_CFLAGS and SHD_CFLAGS, respectively.
Similarly named variables are provided for LDFLAGS.

A module may select to use a particular build type for its suffix
rule by including either Makefile.lwp, Makefile.pthread or
Makefile.shared from src/config. This creates an appropriate .c.o
suffix rule, defines AFS_CFLAGS and AFS_LDFLAGS as appropriate, and
creates two rules AFS_CCRULE and AFS_LDRULE, which can be used to
build, and link objects. For example:

foo.o: foo.c
$(AFS_CCRULE) foo.c

foo: foo.o
$(AFS_LDRULE) foo.o

If a you wish to override the CFLAGS or LDFLAGS for an object build
using these rules (or through the .c.o suffix rule) you can do so,
by defining CFLAGS_<object> or LDFLAGS_<object>. For example:

CFLAGS_foo.o= -DDEBUG
LDFLAGS_foo = -ldebugging

A module may also alter the behaviour of the compile and link steps
module wide by defining MODULE_CFLAGS or MODULE_LDFLAGS.

This functionality is now used throughout the tree:
    *) Suffix rules are used wherever possible, removing a number of
       unecessary build rules.
    *) All link steps are replaced with AFS_LDRULE
    *) All standard compile steps are replaced with AFS_CCRULE
    *) Unusal compile steps are defined, as far as possible, int
       terms of the LWP_ PTH_ and SHD_ variables.
    *) The use of $? has been removed entirely, as it makes it
       impossible to provide build rules with dependency information

10 years agovos release: Force full dump on RO_DONTUSE sites
Andrew Deason [Fri, 10 Sep 2010 20:52:34 +0000]
vos release: Force full dump on RO_DONTUSE sites

When releasing a volume, currently we perform an incremental dump on
RO_DONTUSE sites if the volume exists on the remote site. Since
RO_DONTUSE implies that we do not expect a site to exist there, delete
the extant volume if we find one and force a full dump.

If we perform an incremental dump, we run the risk of incrementally
dumping to a temporary volume that the administrator is not aware of,
and doesn't have any actual data but has a last update time late
enough that it may be missing some data after the incremental dump. So
to avoid that, force a full dump every time.

Jeffrey Altman [Wed, 15 Sep 2010 23:06:22 +0000]
Windows: Ensure that cm_NameI errors are acted upon promptly

There are many cases in the SMB server where an error from cm_NameI()
was either ignored or not acted upon until several other operations
are performed that could result in the same error being repeated.
This is a mistake which did not have negative side effects until
additional checks for callback status were added recently.

At present, if a CM_ERROR_ACCESS error is returned and ignored,
subsequent attempts to operate on the same cm_scache_t will result
in additional queries to the file server that will also end in an
abort response.  This can trigger the file server to delay responses
to the client.

This patchset ensures that all cm_NameI() errors are acted upon
promptly.

Rx: raise rx_minPeerTimeout to 20ms

At 2ms it is possible for the packet we are sending to be resent
just about immediately as the retryTime computation occurs before
the send takes place and not afterwards.  If the network send blocks,
the retryTime may have already expired.

We do not want rx_minPeerTimeout to be too large though because the
value will end up being used as the backoff time period when the
actual RTT for the connection is less than the rx_minPeerTimeout
value.  Extensive testing shows 20ms to be an adequate compromise
that avoids the vast majority of unnecessary resends without
unnecessarily slowing down the connection if a packet is in fact

10 years agorx: Make statistics interface use Atomics
Simon Wilkinson [Tue, 28 Sep 2010 23:11:53 +0000]
rx: Make statistics interface use Atomics

Make the rx_statistics statistics gathering infrastructure use
atomics for all of its counters. This significantly reduces
lock contention. However, it also (potentially) changes the format
of the rx_stats variable which has been used by callers in the past.

To simplify this process, and to aid with future changes, we remove
direct access to rx_stats. Instead, two additional API functions
rx_GetStatistics and rx_FreeStatistics are provided. These give the
caller access to an 'normal' rx_statistics structure.

Tom Keiser has suggested that we should explore using thread-local
statistics structures, and just aggregating them when we are asked
to report. This is a fine idea, and is equally possible with the
new interface that this patch introduces.

Simon Wilkinson [Tue, 28 Sep 2010 22:48:50 +0000]
rx: Add rx_NewThreadId function

The fileserver and the fsync server were locking an internal RX
mutex, and incrementing an internal counter in order to obtain fake
pthread thread IDs. Instead of letting them muck around in the

10 years agorx: Add atomic operations code
Simon Wilkinson [Tue, 28 Sep 2010 22:37:54 +0000]
rx: Add atomic operations code

Add support for an atomic type, and atomic operators for RX. This
builds on work which has already been done for Windows, where
InterlockedOperations are used for statistics gathering.

A new opaque type, rx_atomic_t is introduced so that normal arithmetic
operations will fail on atomic data.

An implementation using native atomic methods is provided for Darwin,
Solaris and Windows. A native kernel implementation is used for Linux.
Where OpenAFS is built with a sufficiently modern gcc, gcc's atomic
primitives will be used. Sadly, gcc's builtin operations are not
available for i386, they will only be used with builds the set
-march=i486 (or later).

Otherwise, we fall back to a single mutex which protects all atomic
operations.

10 years agoRX: Tidy reader data locking
Simon Wilkinson [Sun, 26 Sep 2010 14:48:54 +0000]
RX: Tidy reader data locking

Data which is accessed only by the reader thread doesn't need to be
protected by call->lock

Remove the call->lock protection where it isn't required, which makes
certain read/write calls lock free.

Stop rx_ResetCall from manipulating reader thread data. This data will
be zero'd and cleared when the reader thread calls rx_EndCall, and
doesn't need to be reset by the Listener thread.

The change which made rx_ResetCall reset reader thread information
was originally part of 559ea99b. It caused race conditions that were
fixed by adding additional lock protection in d0cc6e, 4dadd2 and
423ab97e. This commit reverts portions of all of those changes. It
is safe to not clear the iovc in ResetCall because any NewCall must
be balanced by a corresponding EndCall in the reader thread, and
EndCall does the appropriate freeing of reader elements.

rx: Big windows make us sad

The commit which took our Window size to 128 caused rxperf to run
40 times slower than before. All of the recent rx improvements have
reduced this to being around 2x slower than before, but we're still
not ready for large window sizes.

As 1.6 is nearing release, reset back to the old, fast, window size
of 32. We can revist this as further performance improvements and
restructuring happen on master.
