martin e9e3eb14ae XXX Explicitly make this fail to compile with a proper warning if we
do not have ARP configured.

This can be caused by configurations including bridge, ppppoe or vlan but
no ethernet interfaces - which does not make sense. We should add a way
to config(8) to issue this kind of warnings.

christos 5c8e181780 We are not guaranteed that we have enough bytes to get a struct ip from our
mbuf. So if we receive a short packet, that looks like gif we would panic.
Reviewed by thorpej, tested by Kimmo Suominen and Andreas Wrede. Thanks for
the help in tracking this down.

atatat 31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

thorpej a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

martin a7d662b71c Clear M_BCAST and M_MCAST on outgoing mbufs.
Don't copy ttl from the inner packet to the encapsulating packet. Make
the outer ttl sysctl'able. This should close PR 14269 from Jasper Wallace
(change partly from there) and it makes traceroute work over gre tunnels.

atatat 9dd8465963 (1) Make if_index "wrap" at USHRT_MAX instead of going above it so
that other parts of the kernel won't lose gratuitously.  There are
places where it's assumed that it won't grow that large.

(2) Avoid accidental reuse of occupied slots in the ifindex2ifnet[]
table.

kleink 67dfac7357 Include <machine/intr.h> unconditionally, instead of only doing so if
__HAVE_GENERIC_SOFT_INTERRUPTS and relying on <sys/param.h> to provide it
otherwise; pointed out by Aymeric Vincent.
2002-01-14 18:19:15 +00:00
kleink c095bf1b6d As discussed with Aymeric, <machine/intr.h> is always required, so don't
make its inclusion conditional.

martin 78ce6cb0f8 Initialize the activity timestamp when opening a connection. Only idle-
timeout connection that made it to phase NETWORK yet. (For drivers using
the internal timeout mechanism; isdnd, that does the timeout handling for
ISDN drivers, still needs to be fixed.)

Thanks to Wolfgang Solfrank for finding this.

martin da249d7da1 Implement a retry counter for failed authorizations and limit it to
a configurable maximum (default: 5).

Some ISPs shut down accounts (at least temporarily) after to many bad
retries. This hit me recently due to a stupid pilot error and the fast
retry rate.

martin 99772f59c4 Move net/if_sppp.h to net/if_spppvar.h, create a new net/if_sppp.h
containing the userland visible thinks (i.e. ioctl definitions).

Remove all (both) old ioctls, as they had a brain dead API and made keeping
binary compatibility more or less impossible.

Replace by several new ioctls. While there, remove any arbitrary limits
(resulting from the old, broken ioctls) and allow any length of names
and passwords.

martin b2bd90b630 Cleanup softc more completely on "ifconfig down", but only if we are
currently in a connection reestablishement state.

The previouse (incomplete/unconditional) cleanup confused the state machine.

martin 729b826ecd Fix packet accounting (now netstat -i and netstat -ib show reasonable
values).

Implement a secondary connection-reestablishement mode, which is only
entered after (1) we have successfully transfered payload data over this
connection and (2) if initial retries did not reestablish a session.
In this mode we retry (infrequently) forever, until adminstrator stops
us (by "ifconfig ppppoe0 down"). XXX - need to display this mode in
pppoectl.

It is now possible to pull the DSL modems plug for say 15 minutes, plug
it back in again and just wait. The connection will be reestablished within
three minutes.
