using an EXTERN_INLINE definition for functions that are defined as
inline but provide an externally callable reference.

#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.
Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
Note: the ipf code contains a lot of ifdefs, some of them for NetBSD
versions that are no longer maintained. It won't make the code more
readable, but we should consider removing them.
2031730 4.1.31 Nat drops fragmented packets after the first
http://ipfilter.cvs.sourceforge.net/viewvc/ipfilter/ipfilter/ip_nat.c#rev1.2.2.48
Fixes problems on UDP NFS with ipnat as mentioned in PR kern/38773 and
PR kern/41074. Tested on several slow NFS clients and an i386 server
running ipnat.
Should be pulled up to 5.0.
has been changed from m0 to *mpp. But as *mpp has been set to NULL just
before the call, we end up calling ether_output() with a NULL mbuf,
leading to a NULL pointer dereference. Revert back to using m0 here.
The issue show up when using 'return-rst' or 'return-icmp' in ipf6.conf.
Problem discovered and fix tested on ftp.fr.netbsd.org.
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.

to _ro_rt. Use rtcache_getrt() to access a route cache's struct
rtentry *.
Introduce struct ifnet->if_dl that always points at the interface
identifier/link-layer address. Make code that treated the first
ifaddr on struct ifnet->if_addrlist as the interface address use
if_dl, instead.
Remove stale debugging code from net/route.c. Move the rtflush()
code into rtcache_clear() and delete rtflush(). Delete rtalloc(),
because nothing uses it any more.
Make ND6_HINT an inline, lowercase subroutine, nd6_hint.
I've done my best to convert IP Filter, the ISO stack, and the
AppleTalk stack to rtcache_getrt(). They compile, but I have not
tested them. I have given the changes to PF, GRE, IPv4 and IPv6
stacks a lot of exercise.
The mbuf chain wasn't being walked and thus fin_m was not updated to point
to the new first mbuf with data in it.
Patch from the official IPFilter repository.
alignment and nothing guarantees that IPv6 packets in mbufs are 8-byte
aligned. gcc was coalescing adjacent 32-bit compares into "ldx" on
sparc64, leading to alignment faults when processing icmp6 arriving on
gif with IPv4 outer addresses.
Fix mostly from darrenr@. Discussed extensively on port-sparc64.
set to rn_walktree.
Introduce rt_walktree(), which applies a subroutine to every route
in a particular address family. Use it instead of rn_walktree()
virtually everywhere. This helps to hide the routing table
implementation.
update in ICMP error messages. In the test case for this, the wrong
input was actually being used (it should be the headers from the previous
packet output) and therefore the expected results were also wildly wrong.
