pooka | Separate common bits for all interfaces implementing virtif hypercalls
from Makefile to Makefile.virtif. The latter is meant to be .included.
|

backends in the same rump kernel.

Rerevert to preprevious now that this builds with build.sh
|
| 1.5 | 14-Mar-2013 |
pooka | Guess the RUMPCOMP_USER stuff wasn't ready to be in the NetBSD tree yet,
so revert previous commits to fix build. I'll look at rereverting when
toolchain/47644 is fixed and clean buildtests are again possible.
|
| 1.4 | 13-Mar-2013 |
pooka | Push the bits accessing the networking backend into hypercalls.
This allows a few highly desirable things to happen:
1) Linux support, which is included in this commit (thanks to wanq for
sending me the magic bits for accessing /dev/net/tun)
2) Reusing the kernel-side of the interface for devices such as
hardware packet processors which interact directly with user vm spaces
(not included in the commit).

pooka | branches: 1.3.12; 1.3.22;
Use a bunch of weak symbols to determine which network components
are present. This works in userspace as opposed relying in link
sets, which fail miserably. Later, when the networking stack
becomes modularized, we can move to a dynamic scheme like with file
systems.
Also, this change allows us to do proper autoconfig, namely attach
the loopback interface iff it is present.

pooka | branches: 1.1.2;
Implement a virtual userspace networking interface. This is required
for any sensible operation when running the entire TCP/IP stack in
userspace (as opposed to libsockin which uses host kernel networking
to provide PF_INET).
While this basically works (although it is quite barebones), it
depends on some bit of cleanup in librump and is not built by
default yet.

Introduce RUMP_COMPONENT. It behaves mostly like a simplified
module which is linked into the kernel and cannot be unloaded.
The main purpose is to get the proper constructors run and create
any /dev nodes necessary for said component. Once more of the
kernel (e.g. networking stack and device drivers) are converted to
MODULE and devfs pops up from somewhere, rump components can be
retired.

riastradh | if_attach and if_initialize cannot fail, don't test return value
These were originally made failable back in 2017 when if_initialize
allocated a softint in every interface for link state changes, so
that it could fail gracefully instead of panicking:
https://mail-index.NetBSD.org/source-changes/2017/10/23/msg089053.html
However, this spawned many seldom- or never-tested error branches,
which are risky to have around. And that softint in every interface
has since been replaced by a single global workqueue, because link
state changes require thread context but not low latency or high
throughput:
https://mail-index.NetBSD.org/source-changes/2020/02/06/msg113759.html
So there is no longer any reason for if_initialize to fail. (The
subroutine if_stats_init can't fail because percpu_alloc can't fail
either.)
There is a snag: the softint_establish in if_percpuq_create could
fail, potentially leading to bad consequences later on trying to use
the softint. This change doesn't introduce any new bugs because of
the snag -- if_percpuq_attach was already broken. However, the snag
can be better addressed without spawning error branches, either by
using a single softint or making softints less scarce.
(Separate commit will change the signatures of if_attach and
if_initialize to return void, scheduled to ride whatever is the next
convenient kernel bump.)

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.

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

The API is used to set (or reset) a received interface of a mbuf.

the upcoming change.

ozaki-r | Prevent LWP migrations between CPUs during upper layer processing
This is a contract of psref(9) that is used by upper layer componenets,
e.g., bridge(4).
|
| 1.50 | 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@:

Acknowledgment: riastradh@ greatly helped this work.
Thank you very much!

pooka | Pull in the changes from the dpdk, netmap and snabb switch repos.
There are two major changes:
1) All thread context policy is pushed down to the hypercalls.
This is meant to help performance-mongering implementations be
able to control packet scheduling better (e.g. pin down packet
reception to certain physical cores).
2) Generalize linkstr, meaning that the interface can now take an
arbitrary string which is passed to the create() hypercall. This can
be used to map backend device characteristics to the rump kernel
interface instance.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>. This change includes
the following:
An initial cleanup and minor reorganization of the entropy pool
code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are
fixed. Some effort is made to accumulate entropy more quickly at
boot time.
A generic interface, "rndsink", is added, for stream generators to
request that they be re-keyed with good quality entropy from the pool
as soon as it is available.
The arc4random()/arc4randbytes() implementation in libkern is
adjusted to use the rndsink interface for rekeying, which helps
address the problem of low-quality keys at boot time.
An implementation of the FIPS 140-2 statistical tests for random
number generator quality is provided (libkern/rngtest.c). This
is based on Greg Rose's implementation from Qualcomm.
A new random stream generator, nist_ctr_drbg, is provided. It is
based on an implementation of the NIST SP800-90 CTR_DRBG by
Henric Jungheim. This generator users AES in a modified counter
mode to generate a backtracking-resistant random stream.
An abstraction layer, "cprng", is provided for in-kernel consumers
of randomness. The arc4random/arc4randbytes API is deprecated for
in-kernel use. It is replaced by "cprng_strong". The current
cprng_fast implementation wraps the existing arc4random
implementation. The current cprng_strong implementation wraps the
new CTR_DRBG implementation. Both interfaces are rekeyed from
the entropy pool automatically at intervals justifiable from best
current cryptographic practice.
In some quick tests, cprng_fast() is about the same speed as
the old arc4randbytes(), and cprng_strong() is about 20% faster
than rnd_extract_data(). Performance is expected to improve.
The AES code in src/crypto/rijndael is no longer an optional
kernel component, as it is required by cprng_strong, which is
not an optional kernel component.
The entropy pool output is subjected to the rngtest tests at
startup time; if it fails, the system will reboot. There is
approximately a 3/10000 chance of a false positive from these
tests. Entropy pool _input_ from hardware random numbers is
subjected to the rngtest tests at attach time, as well as the
FIPS continuous-output test, to detect bad or stuck hardware
RNGs; if any are detected, they are detached, but the system
continues to run.
A problem with rndctl(8) is fixed -- datastructures with
pointers in arrays are no longer passed to userspace (this
was not a security problem, but rather a major issue for
compat32). A new kernel will require a new rndctl.
The sysctl kern.arandom() and kern.urandom() nodes are hooked
up to the new generators, but the /dev/*random pseudodevices
are not, yet.
Manual pages for the new kernel interfaces are forthcoming.

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.

Implement a virtual userspace networking interface. This is required
for any sensible operation when running the entire TCP/IP stack in
userspace (as opposed to libsockin which uses host kernel networking
to provide PF_INET).
While this basically works (although it is quite barebones), it
depends on some bit of cleanup in librump and is not built by
default yet.

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.

Pull in the changes from the dpdk, netmap and snabb switch repos.
There are two major changes:
1) All thread context policy is pushed down to the hypercalls.
This is meant to help performance-mongering implementations be
able to control packet scheduling better (e.g. pin down packet
reception to certain physical cores).
2) Generalize linkstr, meaning that the interface can now take an
arbitrary string which is passed to the create() hypercall. This can
be used to map backend device characteristics to the rump kernel
interface instance.

pooka | A simple (void) is apparently too easy and traditional to make
