peer out from sppp_lcp_open() to sppp_lcp_up(). For one, this makes
things look more symmetrical to sppp_lcp_close(), and somehow it also
just occurred to me that an Up event following the open caused the
value of the authentication option to be clobbered.

MFC candidate -- after spending 6 hours tracking this down, I checked and
discovered that it has been in NetBSD for over a year, so it should be safe
for MFC into 4.3-RELEASE
It's not finished yet (I still have to find a way to implement process-
dependent nodes without consuming too much memory, and the permission
system needs tightening up), but it's becoming hard to work on without
a repo (I've accidentally almost nuked it once already), and it works
(except for the lack of process-dependent nodes, that is).
I was supposed to commit this a week ago, but timed out waiting for jkh
to reply to some questions I had. Pass him a spoonful of bad karma :)
Specifically, the cpuid, curproc, curpcb, npxproc, and idleproc members.
Also, if witness is compiled into the kernel, then a list of all the spin
locks held by this CPU is displayed. By default the information for the
current CPU is displayed, but a decimal cpu id may be specified as a
parameter to obtain information on a specific CPU.
list into a public witness_list_locks() function. Call this function
twice in witness_list() instead of using an evil goto.
- Adjust the 'show locks' command to take an optional parameter which
specifies the pid of a process to list the locks of. By default the
locks held by the current process are displayed.
Don't leak iospace when irq allocation fails. (call wi_free())
Call bus_release_resource() with the correct "rid" obtained from
bus_alloc_resource() that's saved in the softc instead of a hardcoded
0.
VFS operation, make use of the calling process's credential. This
solution may not be ideal (there are a number of other possible
proposals, including making use of the proc0 credential, adding a
credential argument to the VFSOP, and switching from a hard-coded
ucred to a hard-coded nfscred), it is simple and appears to
work. The arguments against using simply crget() are fairly
strong: it is the only place in the code (other than a nearly
identical invocation in ncp) where crget() is invoked, other than
in the process credential creation code; as ucred becomes extensible,
this use of crget() without appropriate context results in less and
less meaningful credential data. The implementation here will
probably be tweaked as a result of experimentation and further
exploration of the requirements. In the mean-time, it allows
progress to be made in ucred expansion for new security models without
causing a crash every time df is used on an NFS mounted file system.
This code has been interop tested against FreeBSD and Solaris NFS
servers. While using the process credentials should not introduce
interop problems, please let me know if any turn out to exist.

Also place the macros under #ifdef _KERNEL. Equally hide the internal
structures such as the freelist structs which include condition variables.

immediate value or the accumulator. 0 is the chip's internal
representation for the accumulator, and so 0 is an invalid immediate value
when the accumulator can also be specified as an argument.

overflow the request queue. The reason we want to do this is that we
now push out completed CTIOs as we complete them- this gets the QLogic
working on them quicker. So we need to know whether we can put the entire
burrito out before we start.
We now support conjoint status with data for the last CTIO for both Fibre
Channel and SCSI. Leave the old code in place in case we need to go back
(minor 3 line ifdef).
Ultra-ultra important- *don't* set rq->req_seg_count for non-data
target mode requests in isp_pci_dmasetup. D'oh- this is actually
the tag value area for a CTIO. What *was* I thinking? Boy howdy
does both aic7xxx and sym get awfully unhappy when on reconnect
you give them a constant '1' for a tag value.
function- we did it a bit cleaner. We only use this if a CTIO completes with
!CT_OK state. We now have managed to get away without having to poke around
and trying to find the original ATIO- the csio we're using has the tag_id
and lun values with it which is mostly what we need when we do the putback.
Make sure we correctly propagate AT_TQAE->CT_TQAE for tags. Make sure
we call ISP_DMAFREE only if we had DATA to move.
tag is active for an ATIO, and say that you want to reconnect with
a tag value in a CTIO have *never* been exercised until now. This lossage
derived from Solaris code where this stuff originally came from that is
about 7 years old. Amazing.
We now bundle the incoming tag (legal values are 0..256) as the low
16 bits of the ccb_accept_tio's at_tagid while we put the firmware
handle for this ATIO in the top 16 bits- define some macros to make
this cleaner.
Complete some Ansification.
Redo establishment of default SCSI parameters whether or not
we've been compiled for target mode. Unfortunately, the Qlogic
f/w is confused so that if we set all targets to be 'safe' (i.e.,
narrow/async), it will also then report narrow, async if we're
contacted in target mode from that target (acting in initiator
role). D'oh!
Fix ISPCTL_TOGGLE_TMODE to correctly enable the right channel for
dual channel cards. Add some more opcodes. Fix a stupid NULL
pointer bug.
