Windows: change buf_Find*() signature to accept cm_fid_t

The buf_Find*() functions require a cm_fid_t to match with the
cm_buf_t objects not a cm_scache_t.  Change the signature so
that the cm_scache_t is not required.  It should be possible to

commit in master:
- In GetVerifiedBlob, the output parameter is set to NULL on entry
and dereferenced later on.
- For Linux, the code in afs_linux_readdir was changed to pass a
DirEntry to GetVerifiedBlob.  This is incorrect, the function still
expects a DirBuffer pointer.
- In afs_dir_IsEmpty, the assignment of ep was removed, leaving
the function to dereference this pointer which was never set.

Jeffrey Altman [Fri, 12 Aug 2011 23:02:48 +0000]
Windows: Fix cm_serverRef ref counts

Use Interlocked operations consistently

Simplify cm_ServerInsertList().  It no longer increments the
refCount on the serverRef object.  Instead it leaves the refCount
as is.  Its the caller's responsibility to add a reference if
required.

Add reference counts and hold locks in places where the
volume server list was used unprotected.

9 years agodir: Protect against circular hash chains
Simon Wilkinson [Sat, 16 Jul 2011 21:59:12 +0000]
dir: Protect against circular hash chains

The dir package didn't protect against circular hash chains when
performing directory lookups. A corrupt directory could therefore
cause a client or a fileserver to go into an endless loop if that
directory contained a loop in its hash chain pointers.

Fix this by exiting the lookup if the hash chain has more elements
than the total number of entries in a directory. This maximum number
of entries is taken as being (number of entries per page) * (max
number of pages), which is considerably more than the real maximum
value.

FBSD: catch up with the disappearance of VOP_GETVOBJECT

The vnode operation VOP_GETVOBJECT disappeared in FreeBSD 6.0, an
embarrassingly long time ago.  Six years ago, a kluge was added
to emulate its behavior, but it did not correctly emulate the
return value of the old VOP implementation.  As a result,
osi_VM_StoreAllSegments() could never actually do anything.  Since we
don't support FreeBSD before 8.0, remove all references to VOP_GETVOBJECT
and examine vp->v_object directly instead.

This has the result that osi_VM_StoreAllSegments() will actually do
something now, which may not be desirable.  (Previously, if somehow
the vnode had no associated VM object, it would crash, and otherwise
it would do nothing at all.)

stds.h: introduce AFS_NONNULL

AFS_NONNULL wraps the GCC/Clang function attribute __nonnull__, which
tells the compiler and the static analyzer that the pointer arguments
to a function (or specific ones, if provided) cannot be null.  Note
that GCC has only limited support for warning about violations of these
constraints.

Usage examples:
int myfunc(struct foo *a, bar_t, struct baz *c) AFS_NONNULL((1));

tells the compiler that the first argument cannot be null (but the
third one can).

int myfunc2(struct foo *a, bar_t, struct baz *c) AFS_NONNULL();

tells the compiler that both pointer arguments cannot be null.

dir/vol: Die() really does

Die() is an abort routine shared by the dir and vol modules.  Move its
prototype into dir.h to ensure that its declaration matches its three
different definitions, and add an AFS_NORETURN annotation so that the
static analyzer knows that it aborts.

9 years agoWindows: cm_BkgDaemon should not do cm_SyncOp's job
Jeffrey Altman [Thu, 7 Jul 2011 21:51:58 +0000]
Windows: cm_BkgDaemon should not do cm_SyncOp's job

cm_SyncOp is designed to synchronize operations among multiple
threads.  The background daemon threads should not filter requests
based upon cm_SyncOp states.  Doing so is racy and does not produce
better performance.

9 years agoWindows: Do not release locks on deleted files
Jeffrey Altman [Fri, 29 Jul 2011 22:07:42 +0000]
Windows: Do not release locks on deleted files

If the cm_scache_t flags include CM_SCACHEFLAG_DELETED, do not
bother releasing an outstanding file lock to the file server.
The lock went away when the file was deleted.  Any attempt to
release will fail with VNOVNODE which is translated locally into
CM_ERROR_BADFD.

If a RXAFS_ReleaseLock RPC fails with VNOVNODE, treat it as
success.

Jeffrey Altman [Thu, 28 Jul 2011 19:05:28 +0000]
Windows: permit perl command to be explicitly set

Add PERL variable to the build system.  If not specified
externally the variable will be set to 'perl'.  However,
ActiveState Perl should be used and not Cygwin Perl.  The build
environment should indicate that by specifying a PERL setting.

SET PERL=c:\perl64\bin\perl.exe

or similar.

9 years agomerge-pod changes for cygwin and MSWin32 perl

merge-pod changes for cygwin and MSWin32 perl

On Windows, the git repository is checked out as CR-LF.
Tell perl to open the pod file with cr-lf as the end of line.

On Windows, the input file names are of the form podX\foo.pod.in.
Cygwin perl cannot parse the directory for the file name unless
the path separator is converted from \ to /.
