 1.77  08-Sep-2024  rillig fix a/an grammar in obvious cases
 1.76  05-Jul-2024  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.

Suggested by knakahara@
 1.75  30-Jan-2020  thorpej branches: 1.75.30;
Adopt <net/if_stats.h>.
 1.74  05-Feb-2019  msaitoh branches: 1.74.6;
Remove very old IFF_NOTRAILERS flag.
 1.73  26-Jun-2018  msaitoh branches: 1.73.2;
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.
 1.72  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.71  23-Oct-2017  msaitoh branches: 1.71.2;
If if_attach() failed in the attach function, return.
 1.70  23-May-2017  ozaki-r branches: 1.70.2;
Remove an out-of-date comment

 1.69  23-May-2017  ozaki-r Apply deferred if_start to more drivers

And annotate some XXX_start as it runs in softint to clarify that
it doesn't need deferred if_start.
 1.68  15-Dec-2016  ozaki-r Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
- Where/When if_ipackets is counted up
- Note that some drivers still update packet statistics in their own
way (periodical update)
- Moved bpf_mtap run in softint
- This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net
 1.67  10-Jun-2016  ozaki-r branches: 1.67.2;
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.
 1.66  09-Feb-2016  ozaki-r Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Additional information including performance numbers can be found
in the thread at tech-kern@ and tech-net@:

 1.65  30-Oct-2015  phx Fixed format string types to make it compile with BAH_DEBUG again.
 1.64  27-Oct-2012  chs branches: 1.64.14;
split device_t/softc for all remaining drivers.

 1.63  05-Apr-2010  joerg branches: 1.63.8; 1.63.18;
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.
 1.62  19-Jan-2010  pooka branches: 1.62.2; 1.62.4;
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.
 1.61  10-Jan-2010  snj Add a missing closing parenthesis in a few places. From Henning Petersen
in PR kern/42527.
 1.60  31-May-2009  he Don't include <machine/mtpr.h> anymore since it has been removed
(at least from the amiga port) and appears to no longer be required.
 1.59  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.58  12-Nov-2008  phx branches: 1.58.4;
Added missing #include <net/if_ether.h> for ether_ioctl().
 1.57  07-Nov-2008  dyoung *** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address. (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior. Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability. KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr. That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR. For example, pull ..._init() out of any switch
statement that looks like this:

switch (...->sa_family) {
case ...:
..._init();
...
break;
...
default:
..._init();
...
break;
}

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

switch (x & (IFF_UP|IFF_RUNNING)) {
case 0:
...
break;
case IFF_RUNNING:
...
break;
case IFF_UP:
...
break;
case IFF_UP|IFF_RUNNING:
...
break;
}

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure. Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls. In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source. In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset. Delete unnecessary casts to void *. Use
sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with
NULL instead of "testing truth". Replace some instances of (type
*)0 with NULL. Change some K&R prototypes to ANSI C, and join
lines.

 1.34  23-Mar-2000  thorpej New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Avoid calling m_pullup in a few places, where not necessary.
 1.32  27-Aug-1999  is Factor out arc_storelladdr(), and use that instead of arc_ifattach() in

 1.31  26-Aug-1999  is Only use ifp->if_addrlen after initializing it.\
Problem detected by Andreas Johansson.
 1.30  18-May-1999  thorpej Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
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.

 1.17  07-May-1996  thorpej branches: 1.17.4;
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_start)()
to take a struct ifnet *, rather than a unit number.
 1.16  20-Mar-1996  is - Zeroth version of M68060 support (dont want to cause emulation traps for
the "Fast Assembler Version of the copy loop)
- Yet another sanity check included: initialize unused receive buffers to
zero sender id; and test for sender hardware id of zero in the receiver.
Gives us better error messages in case flaky hardware causes spurious
receive interupts.
 1.15  17-Mar-1996  thorpej New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

It's not required to include net/bpfdesc.h. Remove it.
--
Simplify like other drivers. NULL check of ifp->if_bpf is done in
bpf_mtap(), so it's not required to do it here.
--
Remove duplicated inclusion of net/bpf.h.
--
Remove duplicated inclusion of net/bpf.h.
--
Simplify bpf_mtap() call. No functional change.

if_initalize() and if_attach() failed when resource allocation failed
(e.g. allocating softint). Without this change, it panics. It's bad because
resource shortage really occured when a lot of pseudo interface is created.
To avoid this problem, don't panic and change return value of if_initialize()
and if_attach() to int. Caller fanction will be recover from error cleanly by
checking the return value.
Return if bah_attach_subr() failed.
If if_attach() failed in the attach function, return.
- If if_initialize() failed in the attach function, free resources and return.
- Add some missing frees in bridge_clone_destroy().
- KNF
If error occured in bcmeth_ccb_attach(), free resources and return.
If error occured in pq3etsec_attach(), free resources and return.
If error occured in the attach function, free resources and return.
- If if_initialize() failed in athn_attach(), free resources and return.
- Add missing pmf_event_deregister() in athn_detach().
- Free resources correctly on some errors in atw_attach().
- Use apint*() insread of printf() in the attach function.
If if_initialize() failed in the attach function, return.
- If if_initialize() failed in the attach function, free resources and return.
- Add missing dwc_gmac_free_dma_rings() and mutex_destroy() when attach
failed.
- If if_initialize() failed in the attach function, free resources and return.
- ifp is always not NULL in iwi_detach(). Check correctly with ifp->if_softc.
- If if_initialize() failed in the attach function, free resources and return.
- Fix error path in the attach function correctly.
If if_initialize() failed in the attach function, free resources and return.
If if_attach() failed in the attach function, free resources and return.
- If if_initialize() failed in the attach function, free resources and return.
- KNF
- If if_attach() failed in the attach function, free resources and return.
- KNF
Fix compile error.
Fix compile error.
We don't need '&mii', but just 'mii' for mii_detach().
Don't free sc_rthash twice
