after upgrade to 24.11: squid doesn´t start

Could we do a cp instead just in case?

Thanks

@stephenw10 Hi,

yes, the systems had Squid installed all along, so coming from 2.7.2 onwards.

@JeGr you are a life saver!

It's working again now :)

ps: my system also was updated from a 2.7

Nice. It would be good to confirm everyone hitting this is using an install upgraded from CE.

No that won't fix the problem of the linker pulling the wrong library. If you just copy it, the original is still in /usr/lib and gets pulled via ldd.
That's why I said "move" (mv) it instead of just deleting. Moving IS the backup way instead of plain and simply deleting the old library that seems obsolete. So you're not breaking anything permanently by moving, you can always move it back afterwards if that happens to trigger any other problems, but we have seen none so far on a system with quite a bunch of different packages installed.

Cheers

with out customer that was the case, I'll hit our lab VMs and spin them up to check if some of them has a libc++ in /usr/lib instead of /lib only, but testing will be messy there as our old snapshots aren't recognized as working "plus" anymore (because the VM HW changed after cloning them). But I'll see what we can do.

Hallo,
after upgrading to 24.11 squid can not be started
I always get this:
/pkg_edit.php: The command '/usr/local/sbin/squid -f /usr/local/etc/squid/squid.conf' returned exit code '1', the output was 'ld-elf.so.1: /usr/local/sbin/squid: Undefined symbol "_ZTTNSt3__118basic_stringstreamIcNS_11char_traitsIcEENS_9allocatorIcEEEE"'

Would be curious, if your system was also updated from CE or just an older Plus version. Hope our workaround works for you, too.

Thanks with the updates to fix the major security concerns upstream, I assume that this package will not be removed as the concerns for removing it have been addressed. Please see attached..

This was the email from the Squid development team...

"The Squid Project apologizes for being late in responding to the
publication of 55 vulnerabilities disclosed by Joshua Rogers of Opera Software
at https://megamansec.github.io/Squid-Security-Audit/

We thank Joshua for discovering these bugs and sharing their details with us.
The surprise publication caught us off guard, but Squid
developers had worked on addressing some of the disclosed vulnerabilities
since before that publication. This message summarizes Squid's status on
October 9th, 2024.

As of Squid v6.8, the vast majority of high-impact vulnerabilities have been
addressed. The following disclosed vulnerabilities are still present:


### Vulnerability “strlen(NULL) Crash Using Digest Authentication”

This vulnerability is still present in Squid v6.11. A fix is expected in Squid
v6.12, due any day now.
Digest authentication is disabled by default; the current workaround is
to avoid Digest authentication.

To verify whether your Squid configuration is vulnerable, check whether it
contains "auth_param” directive. Configurations with auth_param directives
mentioning "digest" scheme may be vulnerable.


### pipeline_prefetch (HTTP pipelining of client-to-Squid requests)

All reported pipelining-related vulnerabilities may still be present in Squid
v6. Pipelining code will probably be removed in master branch and become
unavailable in Squid v7. Pipelining is disabled by default.

If you do not need pipelining (or do not know for sure that you need it), do
not enable that performance optimization.

To verify whether your Squid configuration is vulnerable, check whether it
contains a pipeline_prefetch directive. Configurations containing a
pipeline_prefetch directive set to a positive value may be vulnerable.


### ESI (Edge Side Includes)

Most reported ESI-related vulnerabilities are still present in Squid v6. ESI
code has been removed in the master branch and will not be available
in Squid v7.
ESI is disabled in the default build starting with Squid v6.10. In earlier
versions, ESI code is enabled by default, but the risk is moderate because
exploiting this family of vulnerabilities requires Squid to be
configured as a reverse proxy for a malicious origin server.

If you do not need ESI (or do not know whether you need it), disable it with
`--disable-esi` (default for Squid v6.10 and later).

To verify whether your Squid build is vulnerable, run `squid -v`. Squid v6.9
and earlier versions may be vulnerable unless the output contains
`--disable-esi`. Squid v6.10 and later versions may be vulnerable if the
output contains `--enable-esi`.


### Squid v5

Some fixes were backported to Squid v5, but we lack the resources necessary to
support that old version. Folks running Squid v5 and earlier versions should
either upgrade to the latest v6 release or rely on their
integrator/distributor for support.

So it's now fixed upstream and the new version in the package reflects the updated version. Again there is still some software convergence going on with the updates.

Thanks for all you do.

Indeed the plan was to remove it from the package repo; it's still there since there haven't been significant challenges to keeping it and it gives more time for those using it to plan ahead. At this time there is no maintainer for the pfSense package and there are no plans to maintain it.

mv /usr/lib/libc++.so.1 /root

I tried and got this error when I try and restart squid. am on 24.11-RELEASE (amd64)

JeGr

@dauhee That looks like missing files or stuff from de-/reinstall not finishing completely. If unsure, you can easily remove the package and install again or reinstall. But that it starts AT ALL is due to the bad library being moved so it now can start again. Everything after is likely a config or install thing but seeing it started up again for you is very nice!

Should be possible to restore or roll back to your config now. Also keep in mind the other patches above that mentioned problems with the config file format (noTLSv1 etc.) that perhaps need to be patched, too.

But that should at least fix the point with it not starting due to the ld-elf.so error message.

Cheers :)

@dauhee you need to recreate the linker file to the error log folder it is listed incorrectly again.

https://redmine.pfsense.org/issues/14406
I am thinking that 14406 is the same issue for the error log folder mix up again. It jumps from en to en-us sometimes
