Dual licensing is ok. but one of the licenses must be BSD as opposed to BSD-compatibility. BSD is compatible with GPL but many users of FreeBSD are afraid that GPL in FreeBSD will make it GPL and therefore useless for their purposes. BSD-compatibility is not enough. It should also be BSD licensed. -- Cheers, Cy Schubert FreeBSD UNIX: Web: https://FreeBSD.org NTP: Web: https://nwtime.org e^(i*pi)+1=0 From nobody Mon Oct 21 09:21:47 2024 X-Original-To: freebsd-hackers@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4XX9Jm45H3z5YlpV for ; Mon, 21 Oct 2024 09:40:08 +0000 (UTC) (envelope-from Stephane.ROCHOY@stormshield.eu) Received: from mail.stormshield.eu (mail.stormshield.eu [91.212.116.25]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mail.stormshield.eu", Issuer "Sectigo RSA Organization Validation Secure Server CA" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4XX9Jl3Ck6z4qdw for ; Mon, 21 Oct 2024 09:40:07 +0000 (UTC) (envelope-from Stephane.ROCHOY@stormshield.eu) Authentication-Results: mx1.freebsd.org; dkim=pass header.d=stormshield.eu header.s=signer2 header.b=dm+vtmA+; spf=pass (mx1.freebsd.org: domain of Stephane.ROCHOY@stormshield.eu designates 91.212.116.25 as permitted sender) smtp.mailfrom=Stephane.ROCHOY@stormshield.eu; dmarc=pass (policy=quarantine) header.from=stormshield.eu DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=stormshield.eu; s=signer2; t=1729503606; h=From:Subject:Date:Message-ID:To:MIME-Version :Content-Type:Content-Transfer-Encoding; bh=Bb6vlHNGD8WjSisGRNlXvuZO2IxxQ YluaVq5F+BWD8k=; b=dm+vtmA+kmN5iZ/nLt8i2HptIhKHDaw3n23xSFa+S7fsO69e4SOT1F dHd9+cb5e8NDFoIOeSl/qmB8qiLi+/ku0IhYfLnk+HbTUos3f+Zy7uMHOxvEaUo/NNp9sSwux nVIzloS7DapqXd7sWkb0MySPDxLeRB/XZLl+BGMy2BGxGWmzsyMAmm/qWntQ1tWnh9JA6mQhs 16FcQLNxa+bhggwy5C7vNNX/f46G57AEO2Vnvkg0MVyZphGmamOTgjNhdrnLOGeNJ4ZJ4BvNS znEWSfyexc0jqDaYSQQEy6cOlMqNqqwWVUYBuo0NeEkMthKbF7fPJN9hZk30Na+uvYR6g==; User-agent: mu4e 1.10.7; emacs 29.4 From: Stephane Rochoy To: Subject: swapon vs GEOM labels Date: Mon, 21 Oct 2024 11:21:47 +0200 Message-ID: <86ttd5rdze.fsf@cthulhu.stephaner.labo.int> List-Id: Technical discussions relating to FreeBSD List-Archive: https://lists.freebsd.org/archives/freebsd-hackers List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-hackers@FreeBSD.org MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8"; format=flowed Content-Transfer-Encoding: quoted-printable X-ClientProxiedBy: ICTDCCEXCH002.one.local (10.180.4.2) To ICTDCCEXCH002.one.local (10.180.4.2) X-DKIM-Signer: DkimX (v3.60.360) X-Spamd-Result: default: False [-3.98 / 15.00]; NEURAL_HAM_MEDIUM(-1.00)[-1.000]; NEURAL_HAM_LONG(-1.00)[-1.000]; NEURAL_HAM_SHORT(-0.98)[-0.984]; DMARC_POLICY_ALLOW(-0.50)[stormshield.eu,quarantine]; R_SPF_ALLOW(-0.20)[+a:mail.stormshield.eu]; R_DKIM_ALLOW(-0.20)[stormshield.eu:s=signer2]; MIME_GOOD(-0.10)[text/plain]; RCPT_COUNT_ONE(0.00)[1]; MIME_TRACE(0.00)[0:+]; ASN(0.00)[asn:49068, ipnet:91.212.116.0/24, country:FR]; MLMMJ_DEST(0.00)[freebsd-hackers@freebsd.org]; ARC_NA(0.00)[]; FROM_HAS_DN(0.00)[]; RCVD_COUNT_ZERO(0.00)[0]; FROM_EQ_ENVFROM(0.00)[]; TO_MATCH_ENVRCPT_ALL(0.00)[]; TO_DN_NONE(0.00)[]; DKIM_TRACE(0.00)[stormshield.eu:+] X-Rspamd-Queue-Id: 4XX9Jl3Ck6z4qdw X-Spamd-Bar: --- Hi Hackers, I'm playing with glabel(8) and swapon(8) but found a behavior that is somewhat puzzling.

When things are nested like this, it kinda makes sense that label/usbmemstickp1 shows up. geom doesn't enumerate everything and this seems to be a bit of an artifact. I'd expect both label/usbmemstickp1 and label/swap to be there. geom does odd things with devices that are open to keep others from opening them, and this may just be an artifact of this kinda weird behavior.

Hi Hackers,

I'm playing with glabel(8) and swapon(8) but found a behavior that
is somewhat puzzling.

I boot main (b88df1e893c4) with an USB memstick plugged. The
memstick is da0 and hold a freebsd-swap partition, da0p1. This
partition was given the `swap` label using `glabel label` (i.e.,
an automatic label, stored somewhere into da0p1, AFAIK).

=C2=A0 # glabel status
=C2=A0 =C2=A0 =C2=A0 =C2=A0 Name=C2=A0 Status=C2=A0 Components
=C2=A0 label/swap=C2=A0 =C2=A0 =C2=A0N/A=C2=A0 da0p1

Then I give the whole device the `usbmemstick` label using `glabel
create` (i.e., a manual label, not stored anywhere).

=C2=A0 # glabel create usbmemstick da0
=C2=A0 # glabel status
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 Name=C2=A0 Status=C2=A0 Co= mponents

What puzzle me is what happen when I enable swap:

=C2=A0 # sysctl vm.nswapdev
=C2=A0 vm.nswapdev: 0
=C2=A0 # swapctl -l
=C2=A0 Device:=C2=A0 =C2=A0 =C2=A0 1024-blocks=C2=A0 =C2=A0 =C2=A0Used:

=C2=A0 # glabel status
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 Name=C2=A0 Status=C2=A0 Co= mponents
=C2=A0 label/usbmemstick=C2=A0 =C2=A0 N/A=C2=A0 da0
=C2=A0 # swapoff /dev/label/usbmemstickp1

While swap is enabled, the `swap` label is no longer available. It
comes back when swap is disabled.

Note that I also tried to enable swap using the automatic label
(i.e., `swap`). In such a case this is the `usbmemstick` label
that vanish. And the label is even not restored on `swapoff`.

Is it the expected behavior? Am I doing something wrong?

This both makes sense to me, and seems wrong to me.=C2=A0= When
things are nested like this, it kinda makes sense that labe= l/usbmemstickp1
shows up. geom doesn't enumerate everything a= nd this seems to be a bit
of an artifact. I'd expect both lab= el/usbmemstickp1 and label/swap to be there.
geom does odd things= with devices that are open to keep others from opening
them, and= this may just be an artifact of this kinda weird behavior.

It should also be BSD licensed. It depends on from which side of view. Let's limit "can we borrow any code without violating its license?" here. >From the point of view from GPL'ed software, BSD license is 100% compatible. OTOH, from the point of view from BSD licensed software, GPL is incompatible (because BSD license does not force licensees to make their modified/added codes to be GPL'ed). And FreeBSD has, for example, CDDL'ed codes like OpenZFS in tree, without any action to delete them, unlile GPL'ed ones. This is, (my understanding is) because CDDL is considered as BSD-compatible license. There are more, for example, MIT license and so on. So any of BSD-compatible license is/are included in multiple licenses of the codes, FreeBSD can introduce it in tree. This is my guess. > -- > Cheers, > Cy Schubert > FreeBSD UNIX: Web: https://FreeBSD.org > NTP: Web: https://nwtime.org > > e^(i*pi)+1=0 -- Tomoaki AOKI From nobody Mon Oct 21 19:00:01 2024 X-Original-To: hackers@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4XXPqv3RhPz5Zf9y for ; Mon, 21 Oct 2024 19:04:27 +0000 (UTC) (envelope-from dirkx@webweaving.org) Received: from weser.webweaving.org (weser.webweaving.org [148.251.234.232]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature ECDSA (P-384) client-digest SHA384) (Client CN "weser.webweaving.org", Issuer "E5" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4XXPqt3b00z4RZ1 for ; Mon, 21 Oct 2024 19:04:26 +0000 (UTC) (envelope-from dirkx@webweaving.org) Authentication-Results: mx1.freebsd.org; none Received: from smtpclient.apple (83-85-39-103.cable.dynamic.v4.ziggo.nl [83.85.39.103]) (authenticated bits=0) by weser.webweaving.org (8.18.1/8.18.1) with ESMTPSA id 49LJ2s20068388 (version=TLSv1.2 cipher=ECDHE-ECDSA-AES256-GCM-SHA384 bits=256 verify=NO); Mon, 21 Oct 2024 21:02:59 +0200 (CEST) (envelope-from dirkx@webweaving.org) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=webweaving.org; s=shared; t=1729537379; bh=y4rtjh0AZbOtXAi2T1JzKms9NKS1sjchBnNzsmqTEM8=; h=Subject:From:In-Reply-To:Date:Cc:References:To; b=nO78HDVB2G6NFfWrCPds3g7RXHBsZlCFMOorrX+U79SAPIzuArAZNXXsIquswNT8o yXCigjtlPpGvnjHRWXAybTqEei71cXr1b72uTXA8JLEPg/BP/h9coucqhu1JBhMz+n EHyxBONxyLqeNFHCjAgXXjE6BaoW1tZMdHd5jLL4= X-Authentication-Warning: weser.webweaving.org: Host 83-85-39-103.cable.dynamic.v4.ziggo.nl [83.85.39.103] claimed to be smtpclient.apple Content-Type: text/plain; charset=us-ascii List-Id: Technical discussions relating to FreeBSD List-Archive: https://lists.freebsd.org/archives/freebsd-hackers List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-hackers@FreeBSD.org Mime-Version: 1.0 (Mac OS X Mail 16.0 \(3776.700.51.11.1\)) Subject: Re: pyserial.tools.list_port improvement for FreeBSD From: Dirk-Willem van Gulik In-Reply-To: <202410210954.49L9s9sD076618@critter.freebsd.dk> Date: Mon, 21 Oct 2024 21:00:01 +0200 Cc: hackers@freebsd.org Content-Transfer-Encoding: quoted-printable Message-Id: <203ADA8C-A4ED-4849-B89D-6D18664D67D0@webweaving.org> References: <202410210954.49L9s9sD076618@critter.freebsd.dk> To: Poul-Henning Kamp X-Mailer: Apple Mail (2.3776.700.51.11.1) X-Greylist: Sender succeeded SMTP AUTH, not delayed by milter-greylist-4.6.4 (weser.webweaving.org [148.251.234.232]); Mon, 21 Oct 2024 21:02:59 +0200 (CEST) X-Rspamd-Pre-Result: action=no action; module=replies; Message is reply to one we originated X-Spamd-Result: default: False [-4.00 / 15.00]; REPLY(-4.00)[]; ASN(0.00)[asn:24940, ipnet:148.251.0.0/16, country:DE] X-Rspamd-Queue-Id: 4XXPqt3b00z4RZ1 X-Spamd-Bar: ---- On 21 Oct 2024, at 11:54, Poul-Henning Kamp wrote: > I have had reason to muck about with pyserial.

We are building distributed build and testing farm for NuttX RTOS where different boards are attached over multiport USB HUB(s). Build will be repeated with different tools and commits in order to verify a firmware image build, then firmware will be flashed to a physical board in order to perform on-board runtime tests. Logs will be gathered and sent back to a server for analysis (PASS / FAIL + logs). This comes as complementary action to build only verification on GitHub and recent cuts in CI availability (we exceed CI quota by a lot with just standard PR verification). Plus we will have real world hardware runtime verification :-) Also we plan to use https://github.com/mvp/uhubctl for single USB HUB port control. I did not play with that guy yet, is supposed to work on FreeBSD, will have to add support for my i-Tec U3CHARGEHUB16. ugen device is nice to know, but it will change depending on what will be attached to what port, maybe even change in time as HUB ports are cycled, SN is better for target board/interface identification in scripting :-) Thank you :-) Tomek --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info From nobody Tue Oct 22 06:40:36 2024 X-Original-To: freebsd-hackers@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4XXk8j5Dskz59CP8 for ; Tue, 22 Oct 2024 07:20:05 +0000 (UTC) (envelope-from Stephane.ROCHOY@stormshield.eu) Received: from mail.stormshield.eu (mail.stormshield.eu [91.212.116.25]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mail.stormshield.eu", Issuer "Sectigo RSA Organization Validation Secure Server CA" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4XXk8j2tnfz4K2s for ; Tue, 22 Oct 2024 07:20:05 +0000 (UTC) (envelope-from Stephane.ROCHOY@stormshield.eu) Authentication-Results: mx1.freebsd.org; none DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=stormshield.eu; s=signer2; t=1729581603; h=From:Subject:Date:Message-ID:To:Cc :MIME-Version:Content-Type:Content-Transfer-Encoding:In-Reply-To :References; bh=+PQznfpLphmU3+2upG2zp+NGqM5YyIEKkqadWJfFPnA=; b=Pt4jqOVrN iswgucIA1t/XT8IKO//31NSR9M8fLN4cNgVmgpn5C5IaLHzKcF2Y+QDty/RtVFGJNFml5KZVH M/OOkP6GiyTUtNFCCQBU7ts8kOCymWi90AfJdFUhXlz5BBhR0puO4FEn9cPiVMZyjRsGSjTI4 vTWhR0Y8eDFfQMnS5SEi8f35N3I+oRUkzAV9rNINL98kh7ukLKmOHxcvZpOSRo0cMr9If5NBi wuxOFXYyZPOYSMPAoWw6SxYJvr/vS/mnjDsX3NiCYtJ7x4fdtYEg4C5EoikGKQrGS7Nz9oGJe 025MWycWrIQtryzJPMKmdxO7dIo4fxLdL8DFrV6wg==; References: <86ttd5rdze.fsf@cthulhu.stephaner.labo.int> User-agent: mu4e 1.10.7; emacs 29.4 From: Stephane Rochoy To: Warner Losh CC: Subject: Re: swapon vs GEOM labels Date: Tue, 22 Oct 2024 08:40:36 +0200 In-Reply-To: Message-ID: <86plnsr4d9.fsf@cthulhu.stephaner.labo.int> List-Id: Technical discussions relating to FreeBSD List-Archive: https://lists.freebsd.org/archives/freebsd-hackers List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-hackers@FreeBSD.org MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8"; format=flowed Content-Transfer-Encoding: quoted-printable X-ClientProxiedBy: ICTDCCEXCH002.one.local (10.180.4.2) To ICTDCCEXCH002.one.local (10.180.4.2) X-DKIM-Signer: DkimX (v3.60.360) X-Rspamd-Pre-Result: action=no action; module=replies; Message is reply to one we originated X-Spamd-Result: default: False [-4.00 / 15.00]; REPLY(-4.00)[]; ASN(0.00)[asn:49068, ipnet:91.212.116.0/24, country:FR] X-Rspamd-Queue-Id: 4XXk8j2tnfz4K2s X-Spamd-Bar: ---- Warner Losh writes: > On Mon, Oct 21, 2024 at 3:40=E2=80=AFAM Stephane Rochoy=20 > wrote: > > Hi Hackers, > > I'm playing with glabel(8) and swapon(8) but found a behavior=20 > that > is somewhat puzzling. > > I boot main (b88df1e893c4) with an USB memstick plugged.

Well, I have to admit I'm a bit disappointed by the fact labels don't completely mimic devices. What I'm trying to achieve is to provide some sort of hardware abstraction. I wrote a command that is responsible for probing hardware and expose the fact that, e.g., an USB memstick is available, a read/write SD card is inserted, etc=E2=80=A6 My first attempt was to use symlinks in /dev/. The problem with this approach is that GEOM don't seems to dereference them. For example, if I have /dev/sdcard =E2=86=92 /dev/da0, I cannot do things like= =20 `geom disk list sdcard`. IOW, the GEOM API is defeated by symlinks. That's why I'm playing with labels. If symlinks and labels are not well suited for that, do you know of some alternative I could look at?

Let me rephrase.=C2=A0

I would like to modernize the wifi stack so that ioctls are not = used anymore in ifconfig scan operation, for example. I would like to use n= etlink instead.

It depends on from which side of view.
Let's limit "can we borrow any code without violating its license?= "
here.

>From the point of view from GPL'ed software, BSD license is
100% compatible.

OTOH, from the point of view from BSD licensed software, GPL is
incompatible (because BSD license does not force licensees to make
their modified/added codes to be GPL'ed).

And FreeBSD has, for example, CDDL'ed codes like OpenZFS in tree,
without any action to delete them, unlile GPL'ed ones.

This is, (my understanding is) because CDDL is considered as
BSD-compatible license. There are more, for example, MIT license and so
on.

So any of BSD-compatible license is/are included in multiple licenses
of the codes, FreeBSD can introduce it in tree.

This is my guess.

It depends on from which side of view.
Let's limit "can we borrow any code without violating its license?= "
here.

>From the point of view from GPL'ed software, BSD license is
100% compatible.

OTOH, from the point of view from BSD licensed software, GPL is
incompatible (because BSD license does not force licensees to make
their modified/added codes to be GPL'ed).

And FreeBSD has, for example, CDDL'ed codes like OpenZFS in tree,
without any action to delete them, unlile GPL'ed ones.

This is, (my understanding is) because CDDL is considered as
BSD-compatible license. There are more, for example, MIT license and so
on.

So any of BSD-compatible license is/are included in multiple licenses
of the codes, FreeBSD can introduce it in tree.

This is my guess.
