KAUTH_REQ_NETWORK_NFS_EXPORT and KAUTH_REQ_NETWORK_NFS_SVC, and use them
to replace two KAUTH_GENERIC_ISSUSER calls in the NFS code.
Also replace two more with KAUTH_SYSTEM_MKNOD, where appropriate.
Documetnation and examples updated. More to come.
Make the FreeBSD and Linux compat code convert the parameters to their
native representation and call the native routines.
Remove KAUTH_PROCESS_SCHEDULER_GET/SET.
Update documentation and examples.
XXX: For now, only the Linux compat code does the priority conversion
XXX: right.
Linux priority conversion code from yamt@, thanks!
Okay yamt@.
words, don't pass an action and a request, and just use a single action to
indicate what is the operation in question.
This is the first step in fixing PR/37986, which calls for policy/priority
checking in the secmodel code. Right now we're lacking room for another
parameter required to make a decision, and this change makes room for such.
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.
- Add a KAUTH_PROCESS_SCHEDULER action, to handle scheduler related
requests, and add specific requests for set/get scheduler policy and
set/get scheduler parameters.
- Add a KAUTH_PROCESS_KEVENT_FILTER action, to handle kevent(2) related
requests.
- Add a KAUTH_DEVICE_TTY_STI action to handle requests to TIOCSTI.
- Add requests for the KAUTH_PROCESS_CANSEE action, indicating what
process information is being looked at (entry itself, args, env,
open files).
- Add requests for the KAUTH_PROCESS_RLIMIT action indicating set/get.
- Add requests for the KAUTH_PROCESS_CORENAME action indicating set/get.
- Make bsd44 secmodel code handle the newly added rqeuests appropriately.
All of the above make it possible to issue finer-grained kauth(9) calls in
many places, removing some KAUTH_GENERIC_ISSUSER requests.
- Remove the "CAN" from KAUTH_PROCESS_CAN{KTRACE,PROCFS,PTRACE,SIGNAL}.
Discussed with christos@ and yamt@.
Been running in my tree for over a month at least.
Reviewed and okay yamt@, and special thanks to him as well as rittera@
for making this possible through fixing NDIS to not call fork1() with
l1 != curlwp.
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.

Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?). Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it. This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.
There's still a little to do on this front, but this was the major
fs interface blast.
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.
libpuffs.
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.

servers. Calling daemon() (i.e. fork()ing) inside a library can
cause nice surprises for e.g. threaded programs. As discussed with
Greg Oster & others.
avoid wasting unbelievable amounts of memory, set the blocksize to
something more believable. Should fix the memset-part to act only
up to the size the file is extended to, though.
