13 years agorx mtu discovery constrainment code
Derrick Brashear [Tue, 1 Jun 2010 17:10:32 +0000]
rx mtu discovery constrainment code

this code makes us work in the face of a sub1500 mtu network.
a subsequent commit is needed to make it more effective: attempts
to grow the mtu must be scheduled so we aren't forced to heavily
brute-force on failure to discover the exact mtu immediately;
for performance, we do want to grow to the real mtu.

Windows: Support building a lite-client installer

If LITECLIENT is defined when invoking the WiX based MSI installer
build, we will build a light-weight client installer MSI.  This
minimizes the size of the installer for users who only need client
functionality from OpenAFS.

The light-weight client excludes:

  - Server components
  - Control center components
  - Administration utilities
  - Debug symbols

Lite-client installer can also be built by invoking target wix-lite
from the root NTMakefile.

"fs checkservers" during cache creation can crash client

Many pioctl calls pass as soon as the afs_resourceinit_flag is set,
which happens relatively early, alas before the cell name is set.
PCheckServers and others need the latter and dereference NULL.

Easiest: set the cell name as soon as it is known and the dynroot initialisation
piggy-backed to it can be done.

up: refuse multicharacter arguments

The 'up' command currently silently accepts and discards extra
characters when specifying arguments. This can produce rather
confusing behavior such as mistyping '-v -1' as '-v-1' resulting in
the '-v' switch being honored, but the '-1' being ignored. The same
thing occurs for specifying '-v1', even though the usage message
implies that you can combine arguments.

So instead, report an error message for any arguments specified that
are longer than 2 characters, since they are never valid.

Rod Widdowson [Thu, 20 May 2010 17:27:11 +0000]
Rewrite vldb_check -fix

vldb_check -fix was very 'topical' in nature.  It showed signs that
each sucessive corruption had been treated as a one off needing a
specific fix.  This made the code difficult to understand and
incomplete: for instance a single volume on the wrong hash only was
not corrected.  Further there was some rather unfortunately code which
would under certain circumstances stamp the last volume at various
places across the file.

This checkin removes all the old code and replaces it with a
'systematic' fix.  During the last scan across all the volumes, all
four of the hash chains are rebuild from the ground up.  We can then
get rid of the outer 'Mung Until Now Good' iteration and further we
benefit from a linear run time.

Tested by building several different forms of broken-ness in all three
chains and then fixing it.

Now with improved logging and correct non insertion of nonexistant elements
and clean compiled with extra warning.

concepts.

Replace the Kerberos Server terminology with Kerberos KDC and add

KDC.  Remove some remaining Authentication Server references.  Add

from Kerberos principals to AFS IDs.

Remove some now-obsolete distinctions and concepts between mainframes
and workstations and recommendations for server systems.

Reorganize the order in which the servers are discussed to follow a
somewhat more natural order.

Be clear that the Backup Server is optional and that there are other

Russ Allbery [Thu, 27 May 2010 04:23:10 +0000]
Add k_haspag to libkopenafs

Add the k_haspag function to libkopenafs, which returns true if the
current process is in a PAG and false otherwise.

The implementation currently duplicates code from the ktc_curpag
function since the latter calls the regular pioctl() interface and
hence introduces an Rx dependency that we're avoiding for libkopenafs.
This should be refactored to avoid the code duplication at some point,
but that will require building a utility library that can be reasonably
linked into libkopenafs and is therefore deferred for future work.

Add an OpenAFS config file parser

This adds a Kerberos INI style config file parser to OpenAFS, using
the parser contained in Heimdal as a base. Currently, it only exports
a very small number of functions, but exporting further functions is
simply a matter of adding additional shims to hide the Kerberos
context and other specifics.

Note that we don't want to just use the parser as a library because
firstly, we don't want OpenAFS to have a Kerberos dependency (as
other crypto mechanisms will, and do, exist). Secondly, MIT and
Heimdal use a different API here, so we would have to shim anyway.
Also, our own parser means that we don't need to worry about passing
in the krb5 context, and all of the issues that that presents.

We have to check that we can use the keyrings because there was a

13 years agoFix libafs_tree's cross-architecture support
Russ Allbery [Tue, 25 May 2010 03:03:49 +0000]
Fix libafs_tree's cross-architecture support

The results of libafs_tree are supposed to build on any platform that
shares the same basic kernel code, but this had broken in two ways:
libafs_tree was including a pre-built afs/param.h, which needs to be
regenerated on different architectures, and the Linux kernel build
makefile was being pre-generated despite having some architecture-specific
options.

Copy over more of src/config and postpone generation of afs/param.h and
generation of libafs/Makefile to the libafs build.

Remove the substitution of AFS_SYSNAME from make_libafs_tree.pl; it was
unused and now definitely shouldn't be used since it will break the
architecture-independence of the resulting tree.

Simon Wilkinson [Mon, 17 May 2010 19:15:46 +0000]
Fileserver: Don't sync every 10 seconds

The patch which moved our calls to fsync into the background, added
a sync prior to each batch of fsync calls. This is an incredibly bad
idea.

POSIX says that sync "shall cause all information in memory that
updates file systems to be scheduled for writing out to all file
systems". On Linux this means that we in effect perform an fsync()
on every open filehandle on the entire system, and in addition flush
all superblocks and journals out to disk. This makes the following
fsync() calls superfluous - sync() will have already written out
all of the data.

Add to this the fact that the fileserver is doing this every 10
seconds, and this becomes a major performance bottleneck,
particularly if the machine uses a journalled fs - as any disk
operations will end up blocking whilst the journal is written to
disk.

Flags).  This is because it is doing a htonl on what is a char field.
The read code already has a comment "make sure not to ntohl these,
as they're chars, not ints".

This change strips the corresponding htonl from writeheader (and puts
in a similar comment).

Demand Attach: Volumes and vnodes are different

fssync-debug attempts to copy sizeof(Volume) bytes into an object
defined as a Vnode, a sure fire way to make things go boom.

gcc on Snow Leopard picks this up as a buffer overflow, and warns about
it. Fix the problem by only copying sizeof(Vnode) bytes.

Demand Attach: Simplify __VVGC_entry_cl_add

The __VVGC_entry_cl_add was giving an uninitialised variable warning
for empty_idx, because it was using a separate variable, empty_found
as a sentinel for when empty_idx was holding a real value. Simplify all
of this by removing the sentinel, and making empty_idx being -1 mean
'not found', and a real value imply found.

Demand-Attach: Remove dangerous trailing else

Change 9aa09f5e634db8a8b2dedf3a749f2a90ef206e2f introduced a
dangerous trailing else into the VScheduleSalvage_r function:

 #ifdef A
    if (foo) {
      ...
    } else
 #endif
 #ifdef B
    if (bar) {
      ...
    }
 #endif
    something_else()

In a situation where we have A && !B, then something_else() ends up
only being run when foo is false. Given that something_else() is
VOL_LOCK, this will not end well.

In the real world, we hit this problen when we build the volume
package with SALVSYNC_BUILD_CLIENT and !FSYNC_BUILD_CLIENT - in
other words, whilst building the fileserver.

Matt's patches in a123bd8ccd brought in support for FBSD 7.0, but
also disabled several calls to afs_PutVCache() for FBSD80 and
higher.  Matt says that that patch was focused on 7.0, so the

We haven't even pretended to work on the 4.X series for quite some

AFS_FBSD_ENV is now equivalent to AFS_FBSD50_ENV (though the

VFS_RELE can call afs_freevfs, which grabs GLOCK. Thus, don't call
VFS_RELE with GLOCK held or we can try to recursively acquire GLOCK
and panic.  This is currently unlikely to occur (sans vfs refcount
unbalances) without support for forced unmounts, since the last vfs
ref will usually come from the caller of afs_unmount(). But it still
may be possible.

13 years agoSolaris: stop NetIfPoller on shutdown
Andrew Deason [Wed, 12 May 2010 18:59:06 +0000]
Solaris: stop NetIfPoller on shutdown

The NetIfPoller code that is enabled on AFS_SUN510_ENV never gets
shutdown properly. The current code looks as if it was intended for
NetIfPoller to recognize the appropriate termState and just return,
but we never wait for it, and so we can complete the shutdown sequence
without NetIfPoller ever knowing that we are shutting down. This can
cause the machine to panic, as we keep attempting to run NetIfPoller
even after libafs has been unloaded.

Since NetIfPoller is fired by default every 30 seconds, we probably do
not want to wait for it to fire during shutdown. Instead, just destroy
the necessary timeout and task queue, which will wait for NetIfPoller
to complete if running, and will just prevent it from running in the
future otherwise.
