Re: Generic reasons for recursive performance not to peg CPU?
Thanks for the response, but you're answering a different question than I asked. :) The question I'm interested in is, Why is the recursive server not pegging the CPU? I should have quoted Sten's context. If the recursive answer contains additional data, that may contributing to the time spent awaiting bandwidth for the delivery of outbound packets.

There seems to be a pile of misconceptions here. (1) There is no requirement at all that a domain name have an A record. It does not have to resolve to an IP address at all.

Or to anything. (3) However, any name MAY resolve to any IP address, routable or not. That doesn't mean there's anything useful, or even related to that domain, at that IP address. (4) 127.0.0.1 is the IP equivalent of the English language word me. If I say, me, I am referring to myself. If you say, me, you are referring to yourself. It cannot be used to direct anyone to somewhere else. In fact, some use it to deflect probers AWAY from themselves, and back on the prober's own server.

Re: A Few Additional Words About CVE-2014-0591
Hmmm, from what I vaguely recall from my software engineering days, was that memcpy() didn't ever handle overlapped memory buffers and that you should consider memmove() in such cases. Doesn't really make sense that it should, though I think I first learned about this during a code review. Don't recall if I had lazily used it once or if it was something an intern had done, but it was a co-worker that had caught it. On 01/13/14 13:13, Michael McNally wrote: Hello, Bind-Users Readers -- Since you are all subscribers to bind-announce as well [You are, aren't you? It's where we make announcements about security vulnerabilities and about new versions of BIND] you are probably already aware that ISC has announced CVE-2014-0591, a vulnerability which can cause BIND to crash while servicing certain queries against an NSEC3-signed zone. The official announcements can be found in bind-announce or at: https://kb.isc.org/article/AA-01078 and new versions of BIND which patch the vulnerability can be found at http://www.isc.org/downloads But we'd like to point out a few additional facts about this advisory which you might find relevant. 1) Security Patches Are Ending for the BIND 9.6-ESV Branch Back in 2012 we announced our intention to retire the 9.6-ESV branch in 2013. We previously extended the EOL (End of Life) date for 9.6-ESV by six months but those six months are almost over and the rescheduled EOL date for 9.6-ESV is upon us. Unless there are extraordinary circumstances justifying it, 9.6-ESV will not receive future security patches and 9.6-ESV-R11 is the last version planned in the 9.6-ESV sequence. BIND 9.9 was designated an ESV version of BIND in May 2013. Users who require long-term support for their version of BIND should migrate to BIND 9.9. 2) Vulnerability to CVE-2014-0591 is OS and libc Dependent We have issued a general warning for the bug that causes CVE-2014-0591, because with security it is better to be safe than sorry, but per our developer's analysis, the bug (which causes an INSIST crash in name.c) can only be triggered on servers using a memcpy call that behave in a certain fashion. This bug went undiscovered until recently because under most memcpy implementations the software behaves safely. However, recent optimizations to glibc's memcpy have exposed the underlying bug on systems using newer versions of glibc. To date our reports of CVE-2014-0591 crashes have all been from Linux users using glibc version 2.18, but because of the multiplicity of Unix-like operating systems and C library variants we cannot represent all others as safe. The safest course of action is to patch the underlying bug and ensure that your server is not vulnerable regardless of memcpy optimizations, but we do believe that users are unlikely to encounter this crash on older glibc versions or on non-Linux operating systems that do not use glibc. Slightly more information about this is available in our CVE-2014-0591 FAQ and Supplemental Information article in the ISC Knowledge Base: https://kb.isc.org/article/AA-01085 ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users -- Who: Lawrence K.

Yes, that's correct, and in fact we're replacing all uses of memcpy() with memmove() in upcoming releases. Oddly enough, I benchmarked both routines in the newest version of glibc on amd64, and found that memmove() consistently runs about 35% faster than memcpy(). So it's both safer *and* faster. On most platforms, memcpy() does work safely with overlapping buffers, but the POSIX standard doesn't require it to do so, and you're not supposed to rely on it. We had a coding error that caused such a copy, but there were no bad effects, so we missed it -- until glibc changed their memcpy() and revealed our mistake.

The patch devs have been silent on their site, and on this list. NBD -- their choice, of course. Who, other than you, has said anything about *need*? You appear to want people to supply you with a new patch because there is a minor change in the code. You were the one complaining about the lack of info. That certainly looks like you need info to keep using the code. and no info on the 3rd-party rpz2 patches since the 9.9.4 release, we're downgrading to rpz1, as included in the supported Bind release (ack'd that rpz2 will be 'in' 9.10.x). You're of course welcome to use/apply any undocumented/unsupported patches you choose to. Otoh, I choose to use as close to a release product as I can functionally get away with. Me, I'm usually running unreleased code with features that havn't even make a alpha release. Yes, I eat my own dog food. I, personally, have zero interest in playing the lab-rat to determine what secondary/hidden effects there _might_ be by using even an 'obvious' patch that's been, in effect, abandoned. -P's have the minimum in changes required to address the particular security problem. The existing patches work fine and unless you are paying Vernon to support you he is under no obligation to respond to you. When the previous -P came out the advice given to the list was just apply the patch. Tho, now that you mention it, one DOES wonder that if it's so 'obvious', why ISC is waiting until 9.10.x to include it in the code ... Because we broke the rule about including a chunks of new code in a non .0 release for this and additional changes are of a level where we would normally only add them at a .0 release. In any case, my question was what the diffs are, and any hints on downgrading . That's all taken care of, so - thanks. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: specifics of downgrading from rpz2 (3rd party patch) - rpz1 (in Bind release) ?
You appear to want people to supply you with a new patch Oh, THAT's what I wanted? Thanks SO much for clearing that up! ... and unless you are paying Vernon to support you he is under no obligation to respond to you. ... You can keep bloviating, but it still doesn't mean you have the slightest connection to any sort of reality. Who said anything about obligations? Exactly which part of asking about downgrading are you not picking up on? ( pssst! hint, hint! re-read the NBD -- their choice of course part) Please go waste someone else's time. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
