Jeffrey Altman [Sun, 9 May 2010 14:15:30 +0000]
Make afsio be useful on Windows and fix bugs

On Windows, the stdin and stdout handles default to text
mode which corrupts data piped through them.  At the start
of readFile and writeFile, the mode is now set to binary.

The ProbeUuid callback is supposed to determine if this
client is the same as the one being requested.  Since we
are advertising a new uuid in TellMeAboutYourself and
WhoAmI, we should perform the uuid check and return a
valid answer in order to avoid confusing the file server.

Add support for TellMeAboutYourself.  On Windows, return
valid interface information.

Always print verbose output to stderr.

Display MB/sec to three decimal places.

In readFile, always perform a AFSFetchStatus operation
otherwise we have no idea what the file size is.

On Windows, the path separator is backslash.

13 years agoWindows: RXAFS_InlineBulkStat errors must be processed via cm_Analyze
Jeffrey Altman [Thu, 6 May 2010 21:12:48 +0000]
Windows: RXAFS_InlineBulkStat errors must be processed via cm_Analyze

RXAFS_InlineBulkStatus does not return errors such as EACCES,
VNOVOL, VNOVNODE, VOFFLINE, VBUSY, VIO, VMOVED, etc. as an RPC return
code.  Instead they are returned in the status info errorCode field
for each file.

Traditionally, the error associated with the first FID in the query
list has been returned to the caller of cm_TryBulkStatRPC().
However, the error has never been processed through cm_Analyze()
which means that the per-vnode processing for VNOVNODE and the volume
global processing for VMOVED, VNOVOL, etc. has never been performed.
As a result, failover to other .readonly volume instances cannot occur,
volume moves will not be handled, and files that have been deleted
are not detected.

This patchset makes the following changes:

1. If an inline bulk operation has been performed and the inline
   errorCode is a volume global error, then that error replaces
   the RPC return code within the cm_Analyze() processing for
   the RPC.  This will affect whether or not a retry operation
   is performed.

2. The variable 'inlinebulk' is reset to 0 at the top of the
   cm_Analyze() loop in case failover from an inlinebulk capable
   file to an inlinebulk incapable file server takes place.

3. The FID that is passed into cm_Analyze() is not a real fid.
   Instead it consists of the cell and volume but vnode = 0.
   This ensures that the error (if any) is not applied to the
   directory object.

4. If an inline bulk operation was performed, prior to performing
   the cm_MergeStatus() operation a vnode a check is made to
   determine if an error was returned for that vnode.  If so,
   cm_Analyze() is called with no connection, a fake cm_req_t,
   the fid, and the error.  This permits cm_Analyze() processing
   to be performed on the file.

Simon Wilkinson [Thu, 6 May 2010 14:00:00 +0000]
Modernise use of AC_CHECK_TYPE

Prior to autoconf 2.13, AC_CHECK_TYPE took two arguments, the type
to check and the a default type to use if that type wasn't defined.
This usage has been deprecated since 2.13, and the AC_CHECK_TYPE
macro itself now behaves differently. Whilst there is a compatibility
mode, the autoconf documentation discourages its use.

We also have an occurence of a slightly more modern AC_CHECK_TYPE,
where we explicitly #define a default value if one isn't provided.
The autoconf manual also discourages this form, however, in favour
of using AC_CHECK_TYPES, and placing suitable typedefs in an
external header file.

Modify our code so we do things in the recommended way.

Windows: Secure C String usage in src\WINNT\afsd\fs.c

The use of strlen, strcat, strcpy, strncpy and sprintf in
src\WINNT\afsd\fs.c does not effectively protect against buffer
overruns and string truncation errors.  This patchset replaces
their use with StringCbLen, StringCbCat, StringCbCopy,
StringCbCopyN, StringCbCopyEx and StringCbPrintf respectively from
strsafe.h.

The functions sscanf, fscanf and scanf do not check for the size of
the parameters so it is prone to buffer overruns. These functions
can be replaced by sscanf_s, fscanf_s, scanf_s when the Visual Studio
compiler version is 1400 or greater.  Also memcpy will be replaced
by memcpy_s which will check for the size of the destination buffer.

In all cases, failure conditions are handled.

Patchset development was mentored by Asanka Herath and Jeffrey Altman.

Solaris: prevent AFS umount while busy

Return EBUSY from unmount if someone still references stuff in AFS.
This prevents kernel panics that can occur on shutdown if we umount
while there is a file in AFS open. Normally a process can hold a file
in AFS open, AFS is unmounted, and the file is closed, triggering our
code which explodes if called after we're unmounted.

This adds VFS_HOLD/VFS_RELE calls whenever we 'create' a vcache, or
retire an old one, to keep track if anyone has an open reference to
us.

13 years agoRefactor afs_NewVCache
Simon Wilkinson [Sat, 7 Nov 2009 00:16:28 +0000]
Refactor afs_NewVCache

afs_NewVCache was a twisty turny maze of #ifdefs and duplicated code.
This makes a number of sweeping changes to simplify this code, and to
move platform specific elements out into their own directories.

*) ShakeLooseVCaches is refactored so that the same code can be used
   both for platforms that support dynamic vcaches, and those which
   don't.
*) afs_NewVCache, ShakeLooseVCaches, and afs_AllocVCache are all
   modified to remove platform specific code, and to call platform
   specific functions.
*) A new platform file 'osi_vcache.c' is created to hold a number of
   platform specific vcache operations:
   *) osi_TryEvictVCache handles the decision of whether a vcache can
      be evicted or not, and does so if required
   *) osi_NewVnode allocates a new vnode
   *) osi_PrePopulateVCache does the necessary population of the
      vcache, before it's threaded onto the VLRUQ and associated hash
      tables.
   *) osi_AttachVnode handles attaching an OS vnode to our vcache,
      where that is necessary
   *) osi_PostPopulateVCache handles the vcache population that must
      occur after we're on the VLRUQ and have a vnode attached.

OpenBSD: Fix bug in setpag() when group list is empty

In OpenBSD, the PAG uses the 2nd and 3rd group slots in the task's
group list. If an application sets en empty group list (such as Samba
does), any existing PAG is lost and any new one is NOT set because
the existing code will set the new group count to 2 instead of 3, and
it leaves the first group entry as garbage (whatever random value the
memory contained), thereby totally messing up the task's group list.
This patch fixes it so that it behaves as expected.

Windows: Restructure cm_LookupInternal addition of Freelance entries

cm_LookupInternal creates Freelance mount points and symlinks
when queries cannot be found in the Freelance root.afs directory.
If the search name is a full cell name for which vldb information
can be obtained, then a mount point is added.  If the search name
is a left-most substring or the full cell name with a dot appended
to it, then a symlink was created.  This approach created a very
poluted Freelance name space.

This patchset makes the following changes:

 1. Do not create symlinks with a dot appended to the cellname

 2. Do not create symlinks where the left-most substring is not
    a full dot separated component of the cellname.

 3. Permit lookups to succeed when we would have created a
    symlink in the past without creating the symlink.

calls whenever the kernel would let it. This is anti-social, as
we've never had sysctl numbers allocated to us. In kernels newer
than 2.6.24, this misbehaviour is detected and punished. In recent
kernels, the binary interface has gone away entirely.

Since 2.6.19, the kernel has supported allocated unnumbered system
calls. These are only available via /proc/sys (and not the using
the legacy, binary, API), but they're really the only interface
available to us.

Change the sysctl registration code to use unnumbered calls whenever
they are available. Unnumbered calls aren't available in 2.4.x, so
completely remove that code there.

Linux: Remove unnecessary crhold on incomplete kernel credentials

When credentials debugging is active in the kernel, sanity checks
in various credentials functions such as get_cred or put_cred
require that they are called with full fledged kernel credentials.
This can be a problem with recent kernels in osi_Init where we
build our own credentials and try to "crhold" them.
Getting a reference doesn't make much sense anyway since we're
using a statically allocated structure that we never try to free
or modify.

As a minimal fix, just don't call crhold when we're using
the kernel credentials structure.

Where vfs_llseek is available to us (it has been since 2.6.8) use that
directly. If vfs_llseek isn't available, then use either the
filesystem's llseek method, or default_llseek (available since 2.6.0),
to ensure we get the proper locking.

Move rxkad/domestic/* into rxkad/ directory proper

Historically, the fcrypt code lived in its own directory, named
'domestic', so that ACLs could be used to prevent nasty foreigners
from getting access to it. Now that those days are gone, having the
domestic directory just complicates builds. Remove it, and reunite
fcrypt with the rest of the tree.

Improve shared library building support

This change removes the need to maintain two forms of symbol export
lists, instead generating the simpler lists required by AIX and Mac OS X
from the more complex Linux and Solaris mapfile. It can only handle
simple mapfiles at present, any more complex files (for example, those
which contain versioning information) will require changes to the
translation script. The now unused .exp files are removed, and a
dependency on the .map file added to the library build line.

This change adds support for export lists to Darwin for the first time.
Doing so identified a number of symbols in libafsrpc that are required
by libafsauthent, which were not being exported. Export these symbols,
and bump the minor revision of the shared library.

13 years agoUnix: Modify disk cache versioning
Simon Wilkinson [Thu, 22 Apr 2010 21:24:11 +0000]
Unix: Modify disk cache versioning

This change increments the disk cache version number, and adds a
structure size record to the disk cache header. All old disk caches
will be replaced when the client is started.

With the various changes made to unify our file handles, and to
support large file handles on Linux, the size of the 'fcache'
structure was modified earlier in the 1.5 series. However, fcache
is also the building block of the CacheItems file, so these changes
inadvertently broke users upgrading from 1.4. In addition, as the
disk cache inode is now a union of many different structures, the
structure size is now potentially volatile across both kernel, and
OpenAFS revisions.

Up the version number so old disk caches are invalidated and won't
crash users who are upgrading. Also take the opportunity to add an
item to the header which stores the size of struct fcache used
by the disk cache. If the size on disk doesn't match that expected
by the kernel module, truncate the cache and start again.

13 years agoUpdate nextVnodeUnique before checking inUse
Andrew Deason [Thu, 22 Apr 2010 16:54:06 +0000]
Update nextVnodeUnique before checking inUse

When attaching a volume, update the nextVnodeUnique field for the
volume, before we do any checks on the volume; for example, checking
inUse, which may result in a demand-salvage if we are running DAFS.

If we do not do this, we can schedule a demand-salvage without setting
nextVnodeUnique, and VUpdateVolume_r will update the volume header
uniquifier to nextVnodeUnique+200, when nextVnodeUnique is not set.
So, we will always set the uniquifier to 200. Fortunately, the salvage
should usually fix the uniquifer anyway.

So, set nextVnodeUnique before doing any of those checks, to avoid
screwing up the uniquifier when taking the volume offline.
