27dba7b8e8 Implement two new BPF ioctls: BPFGHDRCMPLT and BPFSHDRCMPLT, to get/set
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>.

3108a74999 Sync with bpf-1.2a1
- whitespace
	- add rcsid; our sccsid is newer than the one on 1.2a1.
	- change prototype to add mtu
	- change size_t to u_int for consistency.
	- add alignment stuff in bpf_movein
	- add more consistency checks bpf_movein
	- use one uiomove and then bcopy the data in bpf_movein
	- update the comment for the panic when ifpromisc fails.
	- separate the case when we have non blocking I/O and
	  no data and return EWOULDBLOCK
	- check for other errors and return them
	- pass the mtu to bpf_movein
	- Add the BPF_KERN_FILTER junk, just so that we keep up with the code
	- remove BIOCSRSIG, BIOCGRSIG; SIGIO does this well.
	- don't add the SIOCGIFADDR stuff (it is bogus)
	- Check for malloc return for consistency.
	- comment should say poll
	- change formatting to match the current code.
	- save and restore the pcount and flags in case we fail to set the
	  interface into promiscuous mode.
	- fix spelling typo.

4cf4807ab0 if_arc.h is in net, not netinet. 1997-03-17 06:45:20 +00:00
is
07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When
they're called with M_WAIT, they are defined to never return NULL.

4edabe2501 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.

e1f1a3a9a7 Enhancements to the bpf from Stu Grossman <grossman@cygnus.com>:
* grok FIONBIO, FIOASYNC, and TIOC{G,S}PGRP
	* add BIOC{G,S}RSIG; get/set the signal to be delivered
	  to the process or process group upon packet reception.
	  Defaults to SIGIO.

c7d6aa46d5 copy routines should take size_t lengths for prototype consistency.
don't assume that tick is >= 1000; loses badly on alpha (div. by zero)
only try unaligned copies if NetBSD's UNALIGNED_ACCESS symbol is defined.
various misc type size cleanups, mostly short -> int16_t.
