rin | sys: Drop redundant NULL check before m_freem(9)
m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c
Compile-tested on amd64/ALL.

christos | remove htons, it is pointless (thanks joerg@)
|

christos | remove args from ip_randomid() (John D. Baker). When does this file get built?
|
| 1.20 |
| 29-Jan-2020 |
thorpej | branches: 1.20.6;
Adopt <net/if_stats.h>.
|
| 1.19 |
| 22-Dec-2018 |
maxv | branches: 1.19.6;
Replace M_ALIGN and MH_ALIGN by m_align.
|
| 1.18 |
| 14-Sep-2018 |
maxv | Use non-variadic function pointer in protosw::pr_input.
|
| 1.17 |
| 27-Jun-2018 |
msaitoh | branches: 1.17.2;
Add missing BPF_D_OUT. Reported by John D. Baker.
|
| 1.16 |
| 26-Jun-2018 |
msaitoh | Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.
This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.

| 1.15 |
| 21-Jun-2016 |
ozaki-r | branches: 1.15.16;
Replace ifp of ip_moptions and ip6_moptions with if_index
The motivation is the same as the mbuf's rcvif case; avoid having a pointer
of an ifnet object in ip_moptions and ip6_moptions, which is not MP-safe.
ip_moptions and ip6_moptions can be stored in a PCB for inet or inet6
that's life time is different from ifnet one and so an ifnet object can be
disappeared anytime we get it via them. Thus we need to look up an ifnet
object by if_index every time for safe.
|
| 1.14 |
| 10-Jun-2016 |
ozaki-r | Avoid storing a pointer of an interface in a mbuf
Having a pointer of an interface in a mbuf isn't safe if we remove big
kernel locks; an interface object (ifnet) can be destroyed anytime in any
packet processing and accessing such object via a pointer is racy. Instead
we have to get an object from the interface collection (ifindex2ifnet) via
an interface index (if_index) that is stored to a mbuf instead of an
pointer.
The change provides two APIs: m_{get,put}_rcvif_psref that use psref(9)
for sleep-able critical sections and m_{get,put}_rcvif that use
pserialize(9) for other critical sections. The change also adds another
API called m_get_rcvif_NOMPSAFE, that is NOT MP-safe and for transition
moratorium, i.e., it is intended to be used for places where are not
planned to be MP-ified soon.
The change adds some overhead due to psref to performance sensitive paths,
however the overhead is not serious, 2% down at worst.
Proposed on tech-kern and tech-net.
|
| 1.13 |
| 10-Jun-2016 |
ozaki-r | Introduce m_set_rcvif and m_reset_rcvif
The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.
No functional change.
|
| 1.12 |
| 28-Apr-2016 |
ozaki-r | Constify rtentry of if_output
We no longer need to change rtentry below if_output.
The change makes it clear where rtentries are changed (or not)
and helps forthcoming locking (os psrefing) rtentries.
|
| 1.11 |
| 20-Aug-2015 |
christos | include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.
|

|

drochner | branches: 1.9.2; 1.9.4;
remove KAME IPSEC, replaced by FAST_IPSEC
|
| 1.8 |
| 19-Dec-2011 |
drochner | do missing ipsec->kame_ipsec renames
|

ip_randomid: make mechanism MP-safe and more modular.
OK matt@
|
| 1.6 |
| 05-Apr-2010 |
joerg | Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf
check into the inline functions as well the fourth argument for
bpf_attach.
|
| 1.5 |
| 23-Jan-2010 |
minskim | branches: 1.5.2; 1.5.4;
Fix a typo introduced by the bpf linkage change.
|
| 1.4 |
| 19-Jan-2010 |
pooka | Redefine bpf linkage through an always present op vector, i.e.
#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.

degroote | Import pfsync support from OpenBSD 4.2
Pfsync interface exposes change in the pf(4) over a pseudo-interface, and can
be used to synchronise different pf.
This work was part of my 2009 GSoC
No objection on tech-net@

itojun | branches: 1.2.58;
PF from openbsd 3.5. missing features:
- pfsync (due to protocol # assignment issues)
- carp (not really a PF portion, but thought important to mention)
- PF and ALTQ are mutually-exclusive. this will be sorted out when
kjc@csl.sony.co.jp updates ALTQ and PF (and API inbetween)
reviewed by matt, christos, perry
torture-test is very welcomed.
