Re: AW: [PATCH v2 0/7] 22.03 lantiq: add support for x490 Fritzboxes

2022-10-26 Thread Hauke Mehrtens

Hi,

I am also fine if the user has to use image builder. This board is a bit 
special.
Maybe we should allow board specific initram fs root file systems in the 
future. This would also help in other cases where the user has to bot an 
initramfs system for initial flashing. We can do this later.

Hi,

I can understand that it took a long time. The wasp loader kernel module v5 is 
the next in the review list of the remoteproc-linux kernel list.
I will try to deal with Haukes suggestions by the end of the week. With regards 
to the packages, I think wpad is a left over from my tests and I can remove it 
and I will rework the kernel patches.
But for the special packages that are not honored by the build bots, I do not 
really have a solution. For now I was thinking of instructions to use the image 
builder, which also means, that as a start there will not be any downloadable 
images that cover all possible functionality.

Hi all,

Here is my second attempt for initial FritzBox x490 support. 22.03 now
has all the necessary prerequisites, so support can be added according
to the rules.

The original code snippets were submitted by John Crispin (IIRC),
Andreas Böhler and Daniel Kestrel. I carved out the changes I
considered necessary, integrated and tested them and cleaned them up
(hopefully ;)

These are the minimal changes required to run the FB {3,7}490 as DSL
router (tested!). The 5490 is reported to be similar, so I included
it, but could not test it due to lack of hardware.

The wireless on these boxes is offloaded to a secondary SoC which
needs to be provided its own OS. This feature is explicitly left out
here in order to go step by step. I kept some loose ends where they
don't hurt, for future reference.

Changes from v1:


* return to squashfs for the rootfs; ubifs causes too much complexity
esp. for updates, when even the same model can be equipped with
varying flash chip geometries. UBI partitioning and volumes are kept
though.


Hi,

How is this related to the pull request adding support for these devices
on github?
https://github.com/openwrt/openwrt/pull/5075

The pull request on github looks mostly ok to me, I just had some minor
questions.

I also prefer if the CVE number is named in the patch. If this is 
missing somewhere you could send a patch or pull request to rename the

I'm afraid I don't have any explicit examples, but I'll let you know if
find any.  There are some concerns with the older lua I mentioned below,
but I'll need to come back to those. In any case, a suggestion for future
CVE patches.



The OpenWrt project does not have enough resources to maintain 
security patches for the kernel on our own. OpenWrt relays on the LTS 
kernel maintenance and we update to the most recent LTS version every 
few days or weeks in the maintained branches. If some security patches 
are missing in the LTS kernel versions used by OpenWrt it is probably 
best to approach the Linux stable team directly.


See this blog post from Greg Kroah-Hartman, especially the "Keeping a 
secure system" section:

http://kroah.com/log/blog/2018/02/05/linux-kernel-release-model/


Yes, sure. And whether you or I agree with this or not is to some degree
irrelevant, since what matters to the security people is that they see
the bug fixed. In 90% of the cases I was able to dismiss CVEs
since the subsystems in question are not in use by us (or most of OpenWrt
for that matter. e.g, frame buffers), but some tricky ones remain.


I do not care much about such security experts which are just able to 
hand a list of "problems" their broken tool found and now want fixes.


If you found a real problem patches are welcome, but best is probably to 
inform the stable Linux group.


Many security problems in the Linux kernel do not even get CVE numbers, 
relaying only on CVE numbers for the kernel is not reliable.



That said, there's a very large number of patches to the kernel in
OpenWrt; mostly for new device function, pending fixes or whatnot;
I guess few of these are actual security fixes.


It would be good if someone could create a script finds all patches 
which have a Fixes tag referencing a patch we backported.



So, to user space:

dnsmasq 2.86 - my pointing out that CVE-2021-45957 et al are false 
didn't go

over particularly well, even though they have been properly dismissed by
the Simon Kelley and others.


See my mail on the dnsmasq mailing list:
https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2022q1/016161.html


Yes, and was referred to and well understood by myself at least. Still, 
the objection is that Mitre have this as "disputed", which is rather 
unhelpful, and that is what is being focused upon. Obviously I cannot 
fix something that isn't broken and has no fix, so there's no 
satisfactory answer here to a security review beyond getting the CVEs 
dismissed from Mitre.

Long since in OpenWrt patches.

e2fsprogs 1.46.5 - CVE-2022-1304


This is pretty hard to attack. You could provide a patch.


This was the patch I provided here:



I brought in this patch:

diff --git a/lib/ext2fs/extent.c b/lib/ext2fs/extent.c
index b324c7b0..1a206a16 100644


Yes, very large files on OpenWrt are unlikely without external
media.



If would be simply easier on the optics if I was able to ditch 5.1.5 
in the

build and just use 5.3 - is this possible; I'm sure there's been much
discussion on this before, so please point me at that - will it break 
luci?


An update to Lua 5.4 would be good, but I do not know which impact it 
has.


Understood. I'm going to come back to this later in another post.



There's much more, but that's quite enough for now.


OpenWrt is a mostly volunteer run project. Especially (security) 
maintenance does not get paid by companies. If you have some fixes 
tested patches would be really helpful.


Yes, I know, and to say my reliance upon OpenWrt over the years is 
considerable

would be an understatement, but my time is limited as well, and my focus
must be on addressing specifics to the security review.  Still, I felt it
better to at least have a partial discussion here, and do what little I 
can.


I don't necessarily have time to roll patches in a format suitable
for OpenWrt upstreaming; sometimes I think it's more constructive to simply
point out what can be done, and have the maintainers do it. Maybe not 
ideal,

but it's something.

Look for some more posts on specific topics in the near future.

Re: [PATCH v2 2/2] realtek: use assisted learning on CPU port

2022-10-26 Thread Jan Hoffmann

On 26.10.22 at 00:20, Jan Hoffmann wrote:

L2 learning on the CPU port is currently not consistently configured and
relies on the default configuration of the device. On RTL83xx, it is
disabled for packets transmitted with a TX header, as hardware learning
corrupts the forwarding table otherwise. As a result, unneeded flooding
of traffic for the CPU port can already happen on some devices now. It
is also likely that similar issues exist on RTL93xx, which doesn't have
a field to disable learning in the TX header.

To address this, disable hardware learning for the CPU port globally on
all devices. Instead, enable assisted learning to let DSA write FDB
entries to the switch.

For now, this does not sync local/bridge entries to the switch. However,
support for that was added in Linux 5.14, so the next switch to a newer
kernel version is going to fix this.

This is a follow-up to the patch "realtek: don't set L2LEARNING flag in
rtl83xx TX header". An undesired effect of that patch is flooding of

This patch series switches to assisted learning for the CPU port on all
devices, and also fixes some existing issues with setup of unicast L2
entries.

Together with the kernel 5.15 pull request, entries for local/bridge
addresses are added to the switch. I am still not sure why that doesn't
work with the patches in the current kernel. However, the pull request
for the kernel update seems to be in a good shape, so I don't think it
is worth it to investigate that any further.

Tested on RTL838x (HPE 1920-8G) and RTL839x (HPE 1920-48G).

Changes in v2:
  - don't explicitly specify struct name as parameter to sizeof
  - make calculation of SALRN shift offset clearer

Thanks for the respin! Both patches have been applied on master.


Thank you for applying the patches.

My intention for this series was for it to be applied in addition to the 
previous patch "realtek: don't set L2LEARNING flag in rtl83xx TX 
header", but that patch isn't applied. I guess my wording in the cover 
letter was somewhat ambiguous here, and maybe I should have just 
included the change in this series.


However, in terms of actual functionality it shouldn't matter anyways, 
as the L2LEARNING flag in the TX header doesn't have any effect now that 
learning is disabled using the SALRN register. In the end, it just means 
that the explanation of the FDB corruption issue isn't in the Git 
history, and the commit message of eb456aedfe24 ("realtek: use assisted 
learning on CPU port") is now slightly confusing, as it references the 
change to the TX header which doesn't actually exist.


Best,

It's totally impractical.

Can't we bind to 0.0.0.0 and use SO_BINDTODEVICE to make sure it's
really only responding on the right interface ?
With complicated routing setup it changes a bit the behavior, but this
might be the simplest option if we don't want to rely only on the

I have an experimental branch with SO_BINDTODEVICE support,

I also have to reiterate these "security audits", and this is in now
way related to OpenWRT, but the people who like to think they know
security.

o just because a package is installed does not mean it is listening
o go read some docs
o learn how to port scan yourself
o go read some docs
o learn how to write your own exploits
o go read some docs
o quit reading CVEs that are not related to your product(s)
o go read some docs
o join LKML and read what is being done
o go read some docs

Leave us alone - my company uses Linux exclusively - the threats are
handled way faster than any other platform (OpenWRT aside), so tell
your *security* people to hire someone that is not a straight out of
college noob running some 3rd part package collector and actually
learn how to examine a system for exploits.  Just because something is
installed absolutely does not mean it is vulnerable to attack.

This is becoming a headache trying to teach the recently graduated
kids with security degrees or certifications (that are easily handed
out nowadays) how to handle security.  Everyone wants to package
inspect versus network inspect.

Let me tell you something - if I have physical access, there is not a
damn thing you can do to stop me - so just worry about network access
like everyone is telling you.  If your company is not amenable to that
- I would find another job.  I have a rule of thumb - I do not work
for people dumber than me - you should try that rather than trying to
force dumber people to make you change.  Rules of the world
progressing (college class 101).

[PATCH] build: touch stampfile after subtarget run

2022-10-26 Thread Michael Pratt via openwrt-devel
The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.--- Begin Message ---
Each individual build directory has stampfiles
that are touched as part of their build process
when each stage of the build process completes.

However, the subtargets themselves do not touch
the stampfiles that are defined for them.
They are only touched when a target that has
that stampfile as a prerequisite is ran.

For example,
"make tools/compile" will not touch .tools_compile_...
but "make toolchain/compile" will,
after each build directory in tools/ is checked again,
because the stampfile is a prerequisite,
not the tools/compile target itself.

This makes each subtarget touch a stampfile, if defined,
when the subtarget has completed successfully.

A small amount of build time is expected to be saved
when rebuilding after 'make clean' or an interruption.

Can one be curious and ask what is gonna be used instead of lua, or is
that still not 100% decided yet?

Hi,

all errors you quoted are occurring within Lua code. The view rendering etc.
mostly happens in JavaScript on the client side, this is why things /seem/ to
work. Many backend actions are implemented as rpcd plugins in Lua code though,
and all those seem to fail (not register with rpcd in the first place, likely
because the requested interpreter /usr/bin/lua is not there).

Newer Lua versions do have various incompatibilities with Lua 5.1 and the
deprecation of setfenv(), getfenv() in favor to _ENV will require a lot of
refactoring in LuCI framework code.

Since LuCI is in the process of migrating away from Lua, only keeping an
optional compatibility Lua runtime for legacy applications, it is unlikely
that any work will be spent to convert the framework code to later Lua versions.

Re: lua 5.1.5 CVEs / lua 5.3 with luci

2022-10-26 Thread Peter Naulls

My opinion is that openwrt should try and move to a newer version of lua. This 
old 5.1.5 version appears to be unmaintained, and there does not seem to be the 
resources within the openwrt community to change that.


So I naively adjusted the lua5.3 package to add PROVIDES for lua and liblua
and symlinked the /usr/bin/lua5.3 binary to /usr/bin/lua.

In some very superficial testing, skimming through pages, luci
almost works correctly. What I do see on all pages, is this:

RPCError: RPC call to luci/getFeatures failed with error -32000: Object not

Just bear in mind that although this is 22.03, I have some heavyish changes to 
customize luci too. I don't know this particular code, but I can't imagine it 
being hard to fix.


There's some additional similar errors on other pages.

Switch config:

RPCError: RPC call to luci/getSwconfigFeatures failed with error -32000: Object 
not found



Firewall:

RPCError: RPC call to luci/getConntrackHelpers failed with error -32000: Object 
not found


The system log tabs also report: "Unable to load log data: Not Found".

Wireguard: RPC call to luci.wireguard/getWgInstances failed with error -32000: 
Object not found



Suggested fixes?

In any case, this seems like it would be a major internal change in OpenWrt.

[PATCH procd] ubus: add state measurement

2022-10-26 Thread Florian Eckert
Procd has different states during booting. When the system is
booted, it is in the 'running' state. This state is only exited when the
system is shut down cleanly. This state is called 'shutdown'. To find out
what state the system is in and how long it will take to complete this,
the commit adds a new section 'state' to the ubus call system info. There
you can read which state the procd is in and how long it has been in
this state or how long it has been running in the state.

command:
ubus call system info

output:
{
"localtime": 1666795909,
"state": {
"load": {
"active": false,
"duration": 42.667914
},
"early": {
"active": false,
"duration": 1.107519
},
"ubus": {
"active": false,
"duration": 0.536634
},
"init": {
"active": false,
"duration": 123.176279

"running": {

[PATCH] libnl-tiny: set SOCK_CLOEXEC if available

2022-10-26 Thread Joerg Vehlow
From: Joerg Vehlow 

If CLOEXEC is not set on the netlink socket, restarting netifd using ubus
fails with "Failed to initialize system control", because the bind call
in nl_connect fails with EADDRINUSE, due to the inherited socket handle.

Also it does not make sense, to leak the handle to child processes.

See libnl3: ca0fc7558 ("socket: Set SOCK_CLOEXEC if available")
