763fcb92c5 Use m_dup() instead of m_copypacket() for the time being. Not all 
of the code in the kernel properly checks for read-onlyness before
writing into an mbuf data area. When that code is fixed, the m_dup()
can go back to being m_copypacket().

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights 
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

7b38c4e4d9 RFC 1661 requires that all LCP packets are sent with no address and 
control field compression. The ng_ppp(4) node correctly follows this
rule. However, PPPoE is an exception: when doing PPPoE *all* frames
are sent with address and control field compression.

Alter this node's behavior so that when an outgoing frame is received,
any leading address and control field bytes are removed. This makes
this node compatible with ng_ppp(4).

da010626df Followup to previous commit.. 
- It's worthwhile to use untimeout(9), even though we must still protect
  against "false" timeouts, because most of the time it saves having to
  handle a dummy timeout event.
- Slight tweaks to the delayed ACK algorithm paramters.
 2000-07-25 18:57:20 +00:00
Archie Cobbs
678f9e335e Several fixes: 
- Fix slowness when operating over fast connections, where the timeout(9)
  granularity is on the same order of magnitude as the round trip time.
  timeout(9) can happen up to 1 tick early, which was causing receive
  ack timeouts to happen too early, causing bogus "lost" packets.
- Increase the local time counter to 64 bits to avoid roll-over.
- Keep statistics on memory allocation failures.
- Add a new option to always include the ack when sending data packets.
  Might be useful in high packet loss situations. Might not.

e1e1452d61 Make the ng_ether(4) node type dynamically loadable like the rest. 
This means 'options NETGRAPH' is no longer necessary in order to get
netgraph-enabled Ethernet interfaces. This supports loading/unloading
the ng_ether.ko and attaching/detaching the Ethernet interface in any
order.

Add two new hooks 'upper' and 'lower' to allow access to the protocol
demux engine and the raw device, respectively. This enables bridging
to be defined as a netgraph node, if so desired.

f8307e1233 Add two new generic control messages, NGM_ASCII2BINARY and 
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.

This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.

Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.

See /usr/share/examples/netgraph/ngctl for an example of using this.

Also give ngctl(8) the ability to print out incoming data and
control messages at any time.  Eventually nghook(8) may be subsumed.

Several other misc. bug fixes.

3f47e1e357 Fix some bugs; seems to work now. Minor change to the configuration field 
to make the number of compression slots parameter consistent with what
IPCP negotiates (ie, the number of slots - 1).

3949bee834 Revamped and more useful PPP node type, supporting multi-link PPP directly. 
This is one piece of the grand unified PPP daemon concept, whereby using
netgraph nodes enables PPP data to be handled completely in kernel land,
while leaving negotiation/control to be handled by a single user land
daemon, no matter what the link type(s).

This is a safety checkin only; it compiles, but is utterly untested.
