Committed Windows client code to Orange-Branch.

Porting BMI TCP

Add support for post timeout.

merged in changes from summer at LANL

initial support for solaris.  doesn't include /dev/epoll support.  See trac ticket #97.

workaround for bmi tcp testcontext  always returning immediately in shared client/server environments.

fixed type size mismatch between context id in bmi and context id in the job
interface, was causing memory corruption on 32 bit builds

reverse merge from HEAD.

reverse merge from HEAD to directio branch

Fix bug in BMI reference counting.  Previously the server was responsible
for both incrementing and decrementing count while working on a state
machine, but this leaves a window of time between completion of
testunexpected() and the start of a state machine.  If a connection was
reset during this window it could cause state machine to try to use
non-existent BMI address, with some odd results.

This patch adds a flag that the server can use to have BMI automatically
increment reference count on any unexpected message before it is passed to
the server for processing.

Reverse merged and ported to HEAD.

[pcarns]:
tacl-xattr-homedir.patch:
-------------------------
This makes tacl-xattr.sh slightly more portable.  Some Linux distributions have adduser utilities that do not create the home directory for you.  This patch
explicitly does a mkdir -p and chmod after adduser to make sure that required home directories exist.

tacl-xattr-symlink.patch:
-------------------------
This is an important fix to the test script.  It was using the -L argument to getfattr to traverse symbolic links when dumping the ACLs from the test directory.
This
leads to unpredictable results because there was no way to tell whether getfattr would traverse a real directory or its symbolic link first (it depends on the
dirent
order) and the other would always be left out.  ACLs are not supported on symbolic links anyway, so it was just adding noise to the test script.

xattr-symlink.patch:
-------------------------
This is the only change to PVFS2 itself.  Like most Linux file systems, PVFS2 does not support xattrs on symbolic links (despite what is implied by man pages).
This
is due to the fact that symbolic links have 777 permissions by default that would allow anyone on the system to store xattrs in any symbolic link.  This patch
updates
PVFS2 semantics slightly, however, to be more in line with how other file systems implement this.  In particular listxattr() is now allowed (it just returns that
there are zero entries), and setxattr() is implemented to return EPERM rather than EOPNOTSUPP.

pread-pwrite.patch:
-------------------
This fixes a bug in a patch that I submitted earlier to provide a simple alternate AIO implementation.  It defines _GNU_SOURCE in a limited area for dbpf so that
we
can get proper definitions of pread() and pwrite() on Linux.  I tried using _XOPEN_SOURCE=500, but it will break any .c file that includes dbpf.h due to
incompatibilities with Berkeley DB.

zero-dfile.patch:
-------------------
This fixes a bug in the getattr handling on pvfs2-server if it happens to find an attribute structure with the dfile array zeroed out.  In this case, it needs to
set
the attr flag appropriately to prevent the response encoder from segfaulting while processing the array in the response structure.  This condition is very hard to
trigger, but the server should be able to gracefully report the error rather than crashing.

bind-specific.patch:
--------------------
This patch adds a new config file option (TCPBindSpecific) that if enabled tells the server to bind only to its specific IP address rather than using INADDR_ANY.
This is particularly helpful in failover scenarios where you would like one physical machine to assume two ip addresses (and two servers) to run simultaneously
when
another server crashes.  Without this patch you would need to select a different port on each server to prevent collisions.

Reverse merge changes from HEAD to posix-extensions-branch.

[pete] add a connection close set_info option to bmi-tcp so that we can reset the buffer sizes for the connection to the mountpoint server.
[slang] set the defaults for the buffer sizes to 0 in the config file so they
don't get set on new connections unless the config file requests it.

merging small I/O changes to trunk.  The majority of this commit includes the
new small I/O state machines on client and server, and the modifications to
the client IO state machine.  It also includes mods to the zero-fill code
to perform zero-fill of holes only if they exist instead of zero-ing the entire
memory region initially.  Also, some debug stuff has been added to the
state machine processing code to print enter/exit of state machines if sm
debug is enabled.  The genconfig now includes ioports/metaports for running
multiple servers on the same host for testing.

small I/O changes in sio branch for now

Attached patches implements trusted ports and networks similar to
what PVFS1 implemented.
It adds a new <Security> </Security> tag to the fs.conf config file
and parse utilities accordingly. We can edit these later if there
is a strong need.

Within these tags, you have to specify TrustedPorts <Range of ports> and
TrustedNetwork tcp://<network> tcp://<mask>.
I dont know how to support this cleanly on  non tcp/ip bmi
architectures, so currently this only enables it for the bmi_tcp module
alone. (i guess we could do it for bmi_ib module as well but not done
until someone says that is the right thing to do...)

Also adds support for a --trusted argument to the pvfs2-genconfig script
that will prompt for the trusted port ranges and the network address/masks and write it out
to the fs.conf and server.conf file.

Configure now supports a --enable-trusted to enable all these features.
(NOTE that the fs.conf tags (or lack of one) still allow you to not
select these features even if configure was asked to compile with this
option).

this patch also cleans up all the warnings that arises with gcc
(3.4) and --enable-strict build mode.

updates to my event changes to bring them inline with trunk

fixed error reporting for gethostbyname in BMI-TCP
also fixed simple omissions and errors in related code

More doxygen changes.  Working on the kernel code now.

more doxygen work.

more doxygen work.

- applied Nathan's expandtab patch (expandtab-2.patch.gz)

  first referenced at:
  http://www.beowulf-underground.org/pipermail/pvfs2-developers/2004-July/000745.html

- merging in the pvfs2-nm-nb-branch with the main tree
  see ChangeLog for details, or browse the cvs history of the branch
  for full details

added a set_info option to bmi that tells it to be more aggressive when
cancelling operations; bmi_tcp responds by always closing sockets on
cancellation. use like this:
BMI_set_info(0, BMI_FORCEFUL_CANCEL_MODE, NULL)

- started hacking on a way to let servers release bmi resources for addresses
  that cannot be reconnected; commented out for now until I have more time to
  work on it
- also a bug fix on socket cleanup path, making sure not to call close on a
  socket that is already set to -1

added bmi hint to reference count addresses; not doing anything with it yet

convert bmi and flow cancel cases to use new non-errno error code,
PVFS_ECANCEL, instead of the confusing PVFS_EINTR.  Will result in error
messages like this:
PVFS_sys_lookup: Operation canceled (possibly due to timeout)

- cleanup the error codes in bmi by translating them and making them
  more pvfs friendly.  this only fixes the generic bmi and bmi-tcp parts,
  as the other modules will need some similar translation
- bug fix that will not add an invalid socket if detected

Move from bmi_addr_t to PVFS_BMI_addr_t for consistency.

combo PVFS_id_gen_t -> PVFS_BMI_addr_t, formatting, PVFS error code patch.
Ugly.  Sorry if my formatting pisses someone off; at least I'm not using >
80 columns any more :).

moved BMI addr length limit to somewhere globally accessable (although
it should probably reside somewhere else long term?) and made BMI
enforce it

Renamed id_gen_t to PVFS_id_gen_t and moved it definition into pvfs2-types.h.
Also took the #include for id-generator.h out of header files and into .c
files where possible.

turned the "bmi_flag_t buffer_flag" variable into a named enumeration
"enum bmi_buffer_type buffer_type"

got rid of PVFS_flag type and bmi_flag_t.  need to come back later and
convert the buffer_flag variables in BMI to named enumerations; they are
ints for now

Consolidated some redundant types in BMI and converted to a named
enumeration.  Required changing the name of the flags passed in to
bmi_memalloc() and bmi_memfree() all over the place, unfortunately.

added a get_info() option to BMI that can be used to retrieve a void*
pointer to the method specific address structure for a bmi address.
Could be used by a flow protocol that wants to use the same addressing
scheme as BMI.

modified existing BMI API functions to support the concept of
"contexts" and added hooks to create and destroy them.  This is just a
placeholder, contexts aren't actually implemented yet.

added BMI error code mappings (stolen from trove)

modified all of the BMI code to fall in line with the code formatting
style that we want to use now.  Used the pvfs2-mangle-in-place-80col.sh
script (teamed up with a find -exec command) to do so.

vim formatting line fixes, using pvfs2fixbadformat.pl.

renamed a bunch of files in the bmi subdirectory to use dashes instead
of underscores
