11 years agorx: Don't have different args for rxi_FreeCall
Simon Wilkinson [Tue, 28 Sep 2010 23:21:43 +0000]
rx: Don't have different args for rxi_FreeCall

rxi_FreeCall changes its number of arguments depending on whether
locks are enabled or not. That's a little bit nasty to read, so just
change it so that it always takes two arguments, and ignores the
second when it doesn't need it.

11 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.

11 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.

11 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.

11 years agorxgen: Handle complex structures
Simon Wilkinson [Wed, 1 Sep 2010 13:38:58 +0000]
rxgen: Handle complex structures

Servers built using rxgen will break if they take complex
structures as RPC arguments. A complex structure, in this case, is
one which contains an array.

For example an RPC which takes as an argument:

struct MyData {
    opaque somebytes<>;
}

... will cause memory corruption on the server whenever it is called.

This is becase the server stubs emitted by rxgen do not zero out the
contents of the MyData structure, leaving it with whatever garbage may
be on the stack. When XDR comes to populate the somebytes opaque
array, it sees that MyData.somebytes.somebytes_val is non-zero, and
assumes that this is a pre-allocated block into which it can record
the data from the wire. However, it's really just stack garbage, and
so we overwrite memory.

As a fix, this patch creates a new list of 'complex' structures, which
are identified as structures which contain arrays. When a server stub
is created for a function that takes a complex structure, the structure
is set to zero before use, and marked to be freed afterwards.

I suspect that there may be a wider class of complex structures than are
caught by this routine, but this is a start...

Jeffrey Altman [Mon, 20 Sep 2010 12:11:20 +0000]
Rx: Do not hold call lock across memcpy in rx_ReadProc/rx_WriteProc

1.4.x does not hold the call lock across memcpy operations in
rx_ReadProc, rx_ReadProc32, rx_WriteProc, rx_WriteProc32.  The
claim is that the call curpos, curlen, and nLeft fields which
refer to the current packet being processed will not be touched
by any other thread.  Therefore it is safe to drop the call lock
to permit another thread to add packets to the call while the memcpy
is performed in parallel.

This patchset continues to hold the call lock longer than the
original implementation but does drop it for the length of time
it takes to copy data from the packet buffer to the application
buffer.

Jeffrey Altman [Thu, 16 Sep 2010 12:23:41 +0000]
Windows: Negative Caching for Volume Lookups

If a volume lookup returns VL_NOENT or VL_BADNAME, cache the negative
response for five minutes.  This prevents volume lookup storms caused
by the same volume lookup being performed repeated during a short
time period.  This can happen if mount points to volumes that do not
exist are present in a directory that is being evaluated by Windows
Explorer or Common Control File Dialogs.

This functionality is implemented by storing the most recent update
time for the volume group as part of the cm_volume_t.  A non-existing
volume group is identified with a new CM_VOLUMEFLAG_NOEXIST flag.
The presence of the lastUpdateTime value also permits volume location
information to expire at lastUpdateTime + lifetime instead of expiring
all volume information simultaneously each lifetime period.

Marc Dionne [Thu, 1 Jul 2010 15:38:20 +0000]
Linux: normalize error return for emulated syscalls

pagsh and other code expect setpag() and pioctl() to behave like
a regular syscall or pioctl, that is to return -1 on error, with
errno set to the specific error code.
On Linux, the underlying emulation does a straight return of any
error code it gets from the ioctl, and errors are not properly
caught by the callers.

As an example, pagsh won't detect an error from setpag such as
exceeding a keyring quota limit.  With this patch, the user
will see this:

$ pagsh
setpag: Disk quota exceeded
sh-4.1$

The code in proc_afs_syscall is modified to set errno to the error
code and to set errorcode to -1 in case of error.

proc_afs_sycall is reindented while we're changing code there.

We don't need the keyring headers in every file, so reduce
namespace pollution by just including them in osi_groups.c, which is
the only place that uses them.

aklog: Fix weak_crypto tests

The tests for the various ways of enabling weak cryptography fail
with current Heimdal master, because it defines krb5_allow_weak_crypto
but does not prototype it.

Fix this by testing for the Heimdal version (which MIT does not provide)
first, and only if that's not available, try to use allow_weak_crypto.

Marc Dionne [Fri, 10 Sep 2010 01:02:05 +0000]
Warning fix for gcc 4.5 "operation may be undefined" warnings

The inc_header_word and set_header_word macros make repeated use of their
argument, which triggers many (~30) warnings with gcc 4.5, like this one:

./ptutils.c:473:6: warning: operation on â€˜cheader.foreigncount’ may be undefined

Removing the cast to afs_int32 in the macros gets rid of the warning,
and should be safe since we're just getting a small positive integer value
- the offset of the member in the structure - and passing it to the
pr_Write function which expects an afs_int32.

11 years agonamei: Do not remove n_voldir1
Andrew Deason [Thu, 9 Sep 2010 19:10:01 +0000]
namei: Do not remove n_voldir1

When removing data directories in namei_RemoveDataDirectories, do not
remove the n_voldir1 directory (directory X in /vicepa/AFSIDat/X).
Removing this directory can race against the creation of an entirely
unrelated volume, causing the create op to fail (since it tries to
create a directory in a directory that no longer exists).

We don't currently have the necessary locking to make this safe, and
since the overhead of n_voldir1 existing is pretty negligible, just
leave it there. Also add some comments briefly justifying this.

Note that other similar races probably exist for directories under
n_voldir1, but they would only be between volumes in the same VG, and
so are much less likely to occur.
