Trusty has reached EOL and Xenial has reached end of standard support, so I'm marking their tasks as Won't Fix. I've verified this bug on Focal and Jammy and found that apache2 on both systems accepts a worker name whose length is 256 chars, which, although not great, is the fix provided by upstream to this bug. Therefore, I'm marking this bug as Fix Released on Jammy. ** Changed in: apache2 (Ubuntu Xenial) Status: Triaged => Won't Fix ** Changed in: apache2 (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668474 Title: AH00526 when using long ProxyPass worker name To manage notifications about this bug go to: https://bugs.launchpad.net/apache2/+bug/1668474/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

FYI - The recent re-open by upstream is about a non fatal alert AH02808. It would be a new Ubuntu bug to fix that as well (once the dicussion by upstream settled and it is accepted there).

[Bug 1668474] Re: AH00526 when using long ProxyPass worker name
I don't think it is an actual incompatibility since the util function
for copying those values takes into consideration the size of the dst
buffer. As long as it is being lengthened, I think it's OK. It would be
a problem if we were reducing it and src were larger than dst.
#define PROXY_STRNCPY(dst, src) ap_proxy_strncpy((dst), (src),
(sizeof(dst)))
if (PROXY_STRNCPY(bshared->name, uri) != APR_SUCCESS) {
return apr_psprintf(p, "balancer name (%s) too long", uri);
}

Hi Robie, I do not know for certain. One user on the upstream bug mentions it can't be backported because of an API compat issue, but if there's one present I'm sure not seeing it.

Hi Robie, this fix is in Apache SVN trunk but isn't in upstream stable 2.4 release branch yet so all Ubuntu versions will be affected. In addition, no such patch exists in Debian source. https://anonscm.debian.org/cgit/pkg- apache/apache2.git/tree/modules/proxy/mod_proxy.h#n350 and https://anonscm.debian.org/cgit/pkg- apache/apache2.git/tree/debian/patches I think the best bet is to add it as a debian patch for Zesty and coordinate it with the Debian Apache maintainers until it lands in a stable upstream release.

Brian, thank you for the patch. Please see https://wiki.ubuntu.com/StableReleaseUpdates for information on getting Trusty updated. If this patch qualifies to land in Trusty, then please follow as much as you can of https://wiki.ubuntu.com/StableReleaseUpdates#Procedure. In particular, we need to make sure this bug is fixed in Zesty first. It would be also helpful to know if this impacts Xenial, as I don't think it would be appropriate to fix Trusty without also fixing Xenial (otherwise users will regress when they upgrade).
