directly, call the function pointer (*if_input)(ifp, m). The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary. Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
and "pass-filter" and "inbound" and "outbound" qualifiers in the filter
expression, use new "active-filter-in", "active-filter-out", "pass-filter-in",
and "pass-filter-out" without these qualifiers.
This is necessary due to the horrible, awful way "inbound" and "outbound"
were specified for the filter programs when a packet was passed through them.
Basically, the "address" byte in the serial PPP header was overwritten with
a value to indicate the direction. However, the "address" byte doesn't even
exist on PPP headers for all other PPP encaps! So, this old method worked
only for serial encaps, and corrupted packets for all others (PPPoE, ATM, etc.)
to serial encap, change its data link type to DLT_PPP_SERIAL.
* Work around some serious bogosity in the filtering code which utterly
breaks proper functioning of BPF. The PPP code and pppd(8) WILL be changed
to fix this.
select the current medium, (and it is not autoselect), assume no change and
do not try to select the medium. Fixes 'ifconfig le0 medium 10base5' on sparc2
without requiring a 'do nothing' mediachange callback.
and netinet, currently only tested under netinet.
Disabled by default, enabled by compiling the kernel with option
IFA_STATS. Enabling this feature seems to make the ip_output function
take 13% longer than before, which should be OK for people that need
this feature.
- ETHER_ADDR_LEN: length of Ethernet address (actually, we already defined
this).
- ETHER_TYPE_LEN: length of the Ethernet header `type' field.
- ETHER_CRC_LEN: length of the Ethernet CRC (explorer got this already, mostly
because I forgot to commit these changes earlier).
- ETHER_HDR_LEN: total length of the Ethernet header
- ETHER_MAX_LEN: maximum length of an Ethernet frame, including header and CRC
- ETHER_MIN_LEN: minimum length of an Ethernet frame, including header and CRC
Define ETHERMTU and ETHERMIN (payload sizes) in terms of the above constants.
this fixed in the figures (but still not in the text); anyway, the intention
of the ATA is that this is identical to the PHDS specification.
Remove the ...EXC_8782 constant, and change the _EXC_1201 constant to be
a simple ...EXC.
above only; since this is the only occurence, fix it locally rather than in
<sys/cdefs.h> as to not remove all the functionality on pre-2.8 systems.
XXX Shouldn't use zero-length arrays at all.
After booting a current kernel and receiving a few arp requests on the
network it panics (data modified on free list). The panic message is wrong,
as code inspection shows the memory pool for routing entries is intialized
twice, while the routing timer memory pool is never initialized.
table. These are actually subtype+option combos, but these are the
strings displayed by the MII code to indicate 10Mbps full-duplex and
100Mbps full-duplex respectively, and it's Nice that ifconfig(8) can
grok them.
Our other constants also use "ATALK".
Added many new ETHERTYPE constants to sys/net/ethertypes.h, including the
ones from libpcap and tcpdump "ethertype.h" files.
fix last two fixes one more time, this time dealing with ugly
prototype issues, including the fact that the bcopy returns nothing,
but memcpy returns a void *. Never mind that we don't use it...
This was semi-nontrivial, since a function pointer to bcopy gets used
in this file.
Note #1: The catchpacket routine, which takes a function pointer to
bpf_mcpy or memcpy, should probably be converted to take a
flag that just says which is used, so memcpy can be inlined.
Note #2: The code is heavily #ifdef'ed to run on older operating
systems. We probably want to clean that cruft out, unless
someone is planning a new release of the code at LBL (doubtful.)
This allows pppoutput to be called from splimp (e.g., when ipflow is
in use.) without requiring pppasyncstart to run at splimp.
This is believed to fix PR5624.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
the "header already complete" flag. This allows BPF writers to spoof
layer 2 source addresses (providing the layer 2 in use supports it) in
applications where this is necessary. From Greg Smith <greg@nas.nasa.gov>.
use the Ethernet source address speficied in the sockaddr rather than
the interface's Ethernet address, and then fall through to the AF_UNSPEC
case. From Greg Smith <greg@nas.nasa.gov>.
if_fddisubr.c to fastpath IP forwarding. If ip_forward successfully
forwards a packet, it will create a cache (ipflow) entry. ether_input
and fddi_input will first call ipflow_fastforward with the received
packet and if the packet passes enough tests, it will be forwarded (the
ttl is decremented and the cksum is adjusted incrementally).
change pfil_add_hook to put output filters at the tail of the queue,
while continuing to place input filters at the head of the queue. update
the two users of these functions, and document these changes.
fixes PR#4593.
the case mentioned in the PR was fixed as part of PR/2582. There was a similar
case though that was not handled as part of my initial fix, which was fixed
in FreeBSD. I applied the remaining part from FreeBSD and the code matches
now the FreeBSD respective version. [this probably should be pulled up for 1.3]
stripclose(). In strip_watchdog(), make abort if the line has been closed.
This fixes kern/4470 (Wolfgang Rupprecht), which was a bad pointer passed
to b_to_q() from strip_proberadio() called via strip_watchdog(); the tty
hadn't yet been attached to the strip interface.
