Dear FreeBSD Community,
The deadline for the next FreeBSD Quarterly Status update is
July, 1st 2020 for work done since the last round of Quarterly Reports:
April 2020 - June 2020.
I would like to remind you that reports are collected during the last
month of every quarter.
Status report submissions do not need to be very long. They may be
about anything happening in the FreeBSD project and community, and
they provide a great way to inform FreeBSD users and developers about
work that is underway or has been completed. Report submissions are
not limited to committers; anyone doing anything interesting and
FreeBSD related can -- and should -- write one!
The preferred method is to follow the guidelines at the Quarterly
GitHub repository:
https://github.com/freebsd/freebsd-quarterly
Alternatively you can fetch the Markdown template, fill it in, and
email it to quarterly-submissions@FreeBSD.org.
The template can be found at:
https://raw.githubusercontent.com/freebsd/freebsd-quarterly/master/report-sample.md
We look forward to seeing your 2020Q2 reports!
Thanks,
Daniel Ebdrup Jensen (on behalf of quarterly@)

Hello Everyone,
On the 11th July 2020 from 1400-2100 UTC we will be running a coordinated
virtual Bug Squash. FreeBSD has a Problem Report (PR) database[1] where users
and developers are encouraged to file issues and regressions they find in both
the base system and ports tree.
A Bug Squash is a focused session where we try to triage, process, fix and
close as many reports as we can from the PR database. This July 11th Bug Squash
we will focus on closing as many PRs with patches as we can, some rationale for
this is written up here[4].
While we do process and close issues there are a large number of PRs with
patches attached that should be processed. At the time of writing there are:
- all base system PRs with patches (639)[2]
- all base system PRs with patches, but assigned to no one (277)[3]
We will host a google meet at the start of the Bug Squash to provide an
introduction to the process and will use the #freebsd-bugs irc channel on
freenode to coordinate work, triage and discuss PRs and patches.
https://meet.google.com/dfp-fsou-pwi
We look forward to joining you to squash bugs and commit fixes.
- Tom and Allan

FreeBSD doesn't have a direct equivalent of this. It does support NVMe
device emulation in bhyve, but based on loading RDMA drivers above, I'm
guessing this won't meet your needs. Another option would be to use the
nvmf_tgt provided in SPDK (https://spdk.io/). This would give you the
similar functionality to the Linux NVMe target and supports multiple
transports including RoCE.

That's strange. Those mmp threads shouldn't really be consuming much CPU.
Normally they should just sleep all the time.
Do you use the new ZFS multi-modifier protection feature? I guess not.
Do you have 'multihost' property set on any of your pools?
The change you were looking for is
r361383 MFC r354804,r354806,r354807,r354885: 10499 Multi-modifier protection (MMP)

Dear All,
I have installed FreeBSD 12.1. I have set the "hint.uart.0.flags="0x90" in
the /boot/device.hints file. I also have both ddb and gdb listed when I
issue "sysctl debug.kdb.available". So when I launch db using "sysctl
debug.kdb.enter=1" and issue gdb to change the mode to gdb it shows
"Switching to gdb back-end" and doesn't respond to Ctrl+c. I have to reset
the system in order to get the system up.
Regards,
Arka

All this is expected behavior. You have to connect to the gdb backend
over the serial port using kgdb running on a different system after you
see the "Switching to gdb ..." message. Then debug as usual and detach
when done.

Thanks for the reply. I have one more silly question. I have a terminal at
ttyu1 and I can login through telnet and it works fine except when I issue
"sysctl debug.kdb.enter=1" it hangs showing "debug.kdb.enter". I have
checked the freebsd handbook. At it is mentioned in chapter 26.6, I tried
to put "device sio" in my Kern Conf and it gives me build failure. Looking
at the build log it seems it is missing some header file while building
dev/sio.c. Basically I tried to get into db from serial console and failed.
One more thing is in the console after I get into db and launched gdb I
have also tried connecting kgdb from another host, but got timeout while
connecting the target.
Regards,
Arka

Renamed the port from COM2 to COM1 is bios. This set the serial device to
/dev/ttyu0. One more thing is previously I was terminating telnet using
ctrl+] instead of that issued exit from the terminal (may be that resulted
releasing /dev/ttyu0). With these two changes now I am able to connect kgdb.
Regards,
Arka

FreeBSD recently held an election for its governing body called the =
=E2=80=98Core Team=E2=80=99. The newly elected Core Team would like to =
invite you to a virtual town hall meeting. We=E2=80=99ll be holding two =
sessions, one timed well for Europe and the Americas; the other timed =
well for Asia, Africa and India. Sessions will be held at 1800 UTC on =
July 7, 2020 and 0200 UTC on July 8, 2020. See =
https://wiki.freebsd.org/OfficeHours for details on how to join either a =
live stream to watch, or an interactive meeting to participate. A link =
to this agenda (and any updates) will be there as well.
We=E2=80=99ll be discussing the following topics and taking general =
questions at the end. We=E2=80=99ll have a moderator who will help call =
on people in the meeting to ask questions (or to offer comments) as well =
as relay relevant questions from IRC.
=E2=80=A2 Introduce core members -- All the core team members in =
attendance will briefly introduce themselves and say a few words about =
their goals for this core term.
=E2=80=A2 Discuss proposed terminology changes -- Recently, the =
prior core team had sent out a proposal about how to handle shifts in =
language based on societal change. The initial message was poorly =
written and didn=E2=80=99t strike the right tone. We=E2=80=99ll discuss =
it, the underlying issue and how the new core team plans on doing things =
better.
=E2=80=A2 Recruiting for project teams -- When a new core team =
takes over, it=E2=80=99s a good time to assess the needs of each of the =
teams that we have running different aspects of the project, such as =
administering our machines and helping keep FreeBSD secure. One common =
theme is the need for more help. We=E2=80=99ll discuss what teams there =
are, and make a recruiting pitch and answer any questions.
=E2=80=A2 Core TODO List publishing -- To continue the openness =
initiative, the core team will start publishing out TODO list. This will =
be in addition to the normal meeting minutes and other openness ideas. =
The new core team would love to hear from the community how to improve =
our communications.

FreeBSD recently held an election for its governing body called the =
=E2=80=98Core Team=E2=80=99. The newly elected Core Team would like to =
invite you to a virtual town hall meeting. We=E2=80=99ll be holding two =
sessions, one timed well for Europe and the Americas; the other timed =
well for Asia, Africa and India. Sessions will be held at 1800 UTC on =
July 7, 2020 and 0200 UTC on July 8, 2020. See =
https://wiki.freebsd.org/OfficeHours for details on how to join either a =
live stream to watch, or an interactive meeting to participate. A link =
to this agenda (and any updates) will be there as well.
We=E2=80=99ll be discussing the following topics and taking general =
questions at the end. We=E2=80=99ll have a moderator who will help call =
on people in the meeting to ask questions (or to offer comments) as well =
as relay relevant questions from IRC.
=E2=80=A2 Introduce core members -- All the core team members in =
attendance will briefly introduce themselves and say a few words about =
their goals for this core term.
=E2=80=A2 Discuss proposed terminology changes -- Recently, the =
prior core team had sent out a proposal about how to handle shifts in =
language based on societal change. The initial message was poorly =
written and didn=E2=80=99t strike the right tone. We=E2=80=99ll discuss =
it, the underlying issue and how the new core team plans on doing things =
better.
=E2=80=A2 Recruiting for project teams -- When a new core team =
takes over, it=E2=80=99s a good time to assess the needs of each of the =
teams that we have running different aspects of the project, such as =
administering our machines and helping keep FreeBSD secure. One common =
theme is the need for more help. We=E2=80=99ll discuss what teams there =
are, and make a recruiting pitch and answer any questions.
=E2=80=A2 Core TODO List publishing -- To continue the openness =
initiative, the core team will start publishing out TODO list. This will =
be in addition to the normal meeting minutes and other openness ideas. =
The new core team would love to hear from the community how to improve =
our communications.
=E2=80=A2 Git Transition -- To raise awareness, Ed Maste and =
Warner Losh will be giving a brief presentation about the state of the =
project=E2=80=99s planned transition to git. They can answer a few =
questions here, but are also planning an entire office hours on the git =
transition (tentatively scheduled in two weeks).
=E2=80=A2 General Questions -- Time permitting, the new core =
team can answer any other questions or concerns the community might =
have.
Thanks! We look forward to meeting you.

Hi freebsd-hackers@, freebsd-net@,
These two patches that will be described are a continuation of r357092.
r357092 added support for RFC 6598/Carrier Grade NAT (subnet:
100.64.0.0/10) in libalias and IPFW in-kernel NAT.
These two patches add support for RFC 6598 to natd and ng_nat
respectively:
* natd CGN patch: https://reviews.freebsd.org/D23356
* ng_nat CGN patch: https://reviews.freebsd.org/D23461
Currently, CGN support is missing from natd and ng_nat.
Could someone please review and/or commit these patches?
Best,
Neel Chauhan
