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.
- update copyright
- add their rcsid
- initialize some variables later later for consistency
with the current code.
- change char to u_char to match the current code.
- 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.
