Don't hand all the argv options to fuse_main() - it's only interested
in the ones we haven't parsed ourselves.
These changes make the initiator compile and perform discovery successfully
on FreeBSD 6.3. Full login doesn't work yet due to a KSE related bug.

can find.
If the initiator discovers too many targets for it to handle
(currently more than 16), then truncate to the maximum with a loud
warning message, rather than aborting.
In practice, this means that multiple targets can now be used with the
NetBSD iSCSI initiator.

Initial support for multiple targets from the same host.
Base 'MaxTargets' on a #define, rather than hard-coding.

and we need to add 1 to it to get the size of the LUN.
Revert Max LBA calculation when returning the Maximum LBA from the target
to the iinitiator, following an email conversation with Jonathan Kollasch,
who points out a number of things:
+ the NetBSD scsipi driver reads the value returned by the drive and adds
one to it, so that standard SCSI drives return the 0-based Max LBA in a
READ CAPACITY command.
+ it is up to the initiator to add 1 to the Max LBA to find out the size
of the LUN (Jonathan verified this by using the UNH iSCSI initiator on
to a NetBSD target)
+ an analogous change to the NetBSD target (revision 1.34 of
disk.c) is needed.

With a round of applause to Antti Kantee for helping out with puffs
debugging, and a huge thank you to Greg Oster, who has fixed numerous
bugs over the last week (unfortunately, the bugs are all mine), and
provided enthusiasm and drive.
Right now, the initiator is fulling working for only a single target,
and should be considered to be in a state of flux. Having said that,
Greg completed a run of build.sh with the storage on the iSCSI target,
and found times to be within 0.5% of direct attached storage. Cache
effects apply.
The initiator should be portable to everything that uses the FUSE
interface. That's right - a portable iSCSI initiator.
Storage (LUNs exported by the target) is, at the present time,
presented as a regular file called "storage". This will likely
change in the future.

FFS needs a block device, and so vnconfig can be used to sit on top of
the regular file.

This utility uses FreeBSD's libfetch (updated for NetBSD, and to quieten
lint) to provide a BSD-licensed ftp/http/https file system similar to the
old alex utility. The full URL is used as the path underneath the "/ian"
mountpoint.
Sample use as follows:
[19:09:38] agc@inspiron1300 ...examples/refuse/ian 126 > priv ian/obj/ian /ian
[19:09:55] agc@inspiron1300 ...examples/refuse/ian 127 > cat /ian/ftp://localhost/motd
NetBSD 4.99.27 (INSPIRON) #4: Tue Aug 7 13:04:33 BST 2007
Welcome to NetBSD!
This system is running a development snapshot of the NetBSD operating system,
also known as NetBSD-current. It is highly possible for it to contain serious
bugs, regressions, broken features or other problems. Please bear this in mind
and use the system with care.
You are encouraged to test this version as thoroughly as possible. Should you
encounter any problem, please report it back to the development team using the
send-pr(1) utility (requires a working MTA). If yours is not properly set up,
use the web interface at: http://www.netbsd.org/support/send-pr.html
Thank you for helping us test and improve NetBSD.

This file system is based on librefuse and puffs.
The icfs(8) utility can be used to mount an existing directory on a
new mount point. icfs makes use of the virtdir(3) virtual directory
routines. Underneath those virtual directories, the individual
directory entries will be displayed as an exact mirror of the original
directory, except that any capital letters in the original entry's
name will be substituted with an entry name consisting entirely of
lower-case letters.
This is an unusual example of a refuse-based file system which provides
lesser functionality than the file system it sits on.
|
|
Add a function to "normalise" a path to condense multiple repeated '/'
characters into one.
|
|
dmesgfs is another example file system, which displays the device tree
information gained from dmesg(8) as a directory hierarchy. The information
can be displayed in files, or as targets of symbolic links.

intermediate directories have already been created. If not, then

mp3-based files according to artist, genre or year.
Three virtual directories are made available under the mount point -
artists/
genre/
year/
and then virtual directory entries (see virtdir(3)) are created under
these heading directories.
The pkgsrc/audio/id3 package is needed for this file system to function
properly.
Two shell scripts, id3info.sh and id3db.sh, are included to build up
the music database for id3fs to use to build up its virtual
directories.

librefuse-based file systems.
These are especially useful for file systems which present virtual
directory hierarchies to the caller.
The routines build up and manage an array of virtual directory
entries, indexed upon full pathname within the file system. This is
analogous to the way refuse indexes its own entries. Routines are
available to add, delete, and find entries. Each entry can be one of
3 types - file ('f'), directory ('d') or symbolic link ('l'). Each
entry can also be associated with a target, which is a character
string allocated upon addition. This can be useful for virtual
directory entries of the symbolic link type.
The virtual directory entries can be traversed as an ordered list
(the entries are ordered alphabetically), or can be accessed by
directory component, using routines analogous to opendir(3), readdir(3),
and closedir(3).

the BSD world as a "union" file system.
This fanout file system takes a number of directories and makes them
available under a single mount point.
This is more of an example file sytsem than anything else, but is used
as the basis of a number of other file systems which will be forthcoming
"real soon now".

database as a file system.
The file was created in the first place with the following commands:
cp /etc/passwd infile
db -E B -w -f infile -F: -C btree bdb.db
and mounted as follows:
./dbfs bdb.db /mnt
Example use is as follows, using a btree-based database with login
names as the key, and the rest of the passwd file entry as the value:
