I've installed the patch on a 2nd server with heavy traffic, and all run as flawlessly as with the previous patch.

Had this problem on one of my servers (the only one running bind on Bionic), installed this proposed-update package on Thursday morning, 31st, and have not seen this error since then. Searching through my logs I saw this error appearing at least every second day - often more than once a day - and have not seen it now for more than four days!

Hi Łukasz, I'm testing the proposed patch (https://launchpad.net/ubuntu/+source/bind9/1:9.11.3+dfsg-1ubuntu1.10/+build/17958751). As with the previous patch by Bryce (https://launchpad.net/~bryce/+archive/ubuntu/bind9-sru-1804542), everything seems ok by now, with correct operation and absence of the logs that originated this issue.

Hello Tateru, or anyone else affected, Accepted bind9 into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/bind9/1:9.11.3+dfsg- 1ubuntu1.10 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: bind9 (Ubuntu Bionic) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804542 Title: [SRU] Multiple intermittent socket failures during name resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/bind/+bug/1804542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1804542] Re: [SRU] Multiple intermittent socket failures during name resolutions
Can someone help define steps to reproduce this issue? Ideally in a vanilla install or ideally in a container. The SRU process requires a test case for validating the change, that flags the error before the package installation, and checks the absence of the error after the package installation. So, the next step to move forward with this bug is to get such a test case in hand.

The originally flagged patch was [2/2] of a 2-patch set (AIUI), and the second doesn't make much sense to include without the first.

[Bug 1804542] Re: [SRU] Multiple intermittent socket failures during name resolutions
The upstream commit message is vague in explaining what was going on,
but I'm gathering there was uninitialized data in a variable that would
trigger the error message? The fix appears to be switching to a static
buffer and initializing it to {0}.
** Description changed:
+ [Impact]
+ Socket failures due to uninitialized memory during name resolution.
+
+ [Test Case]
+ TBD
+
+ [Regression Potential]
+ Things to watch for would include memory-related issues and faults relating
to long names or addresses. The patch changes memory management for a data
buffer used in socket communication. There could be behavioral differences
between handling of ipv4 and ipv6 addresses.
+
+ [Fix]
+ See comment #7
+ This will need to be backported.
+
+ [Discussion]
+
+
+ [Original Report]
