71e7578499 Mark i4b IPR and SPPP drivers as NET_NEEDS_GIANT(), as they both
interface with the network stack but are not yet sufficiently
synchronized to run without the Giant lock.  It migh be possible
to mark the interfaces as IFF_NEEDSGIANT, but I'm unable to test
that configuration and am unfamiliar with the architecture of
i4b.

f37a929ca1 Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option.  This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device.  This broke things like the snd_emu10k1 device, which required
quotes to make it parse right.  The no-longer-needed quotes have been
removed from NOTES, GENERIC etc.  eg, I've removed the quotes from:
   device  snd_maestro
   device  "snd_maestro3"
   device  snd_mss

I believe everything will still compile and work after this.

3161f583ca Apply error and success logic consistently to the function netisr_queue() and
its users.

netisr_queue() now returns (0) on success and ERRNO on failure.  At the
moment ENXIO (netisr queue not functional) and ENOBUFS (netisr queue full)
are supported.

Previously it would return (1) on success but the return value of IF_HANDOFF()
was interpreted wrongly and (0) was actually returned on success.  Due to this
schednetisr() was never called to kick the scheduling of the isr.  However this
was masked by other normal packets coming through netisr_dispatch() causing the
dequeueing of waiting packets.

436e887e9c Add another ifdef... 2004-07-05 17:58:03 +00:00
Warner Losh
1877e5a42f meta_p is a void *, so a variable that's of type void * can't be
dereferenced directly.  Toss an ifdef around it for the moment and
allow this to compile.  This likely means that priority packets aren't
queued to the special high priority queue.  The maintainer of this
should look into the problem.

This is likely fallout from the netgraph migration to using a more
generic meta tag from the mbug recently.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

1cafed3941 Update netisr handling; Each SWI now registers its queue, and all queue
drain routines are done by swi_net, which allows for better queue control
at some future point.  Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

68e12ba37e Add a fix for the case where the dialout fails. In this case the isp
interface was left in an active, but not connected, state, which resulted
in data being sent to it and the transmit queue filling up. This happened
because the driver never informed sppp that it shoulkd clean up the
connection. This fix informs sppp that it should clean things up.

The fix was actually developed and tested under -stable, so a short MFC
period seems appropriate, say 2 days.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

Bug in i4btel driver read routine corrected. The conditions in the
while() clause caused the receive queue to be referenced before checking
if a channel is connected, leading to kernel panic (do a 'dd
if=/dev/i4btel0 of=/dev/null' on an unconnected tel device, panic will
follow). Correction was to reorder the while clause conditions to check
for connectedness first.
