Re: [clamav-users] Freshclam updates problem
Paul, I think this is probably the same behavior you faced before, exacerbated by the fact that we used a zero-byte patch to force freshclam to download the whole cvd. I have a pretty good idea on how to solve this in a future clamav version, but for now we're working to un-stick the stuck 0.103.1-0.103.3 freshclam clients. All: We created another new version of main.cvd (version 61) along with a small main-61.cdiff file. We did some testing internally and then published it on the CDN. I've confirmed that it's live now and that the main database update is working as expected again on versions 0.102.4 and 0.103.3. The daily database is still stuck for freshclam versions 0.103.1-0.103.3. We're building a new daily database & daily cdiff to un-stick this one. The build is expected to take about 4 hours. After that, everyone should be able to update normally again.

I'm running 0.103.3 on all 3 of my ClamAV installations. On one of the systems (where I have very detailed logging of freshclam), main was still at 59 (today at 7:43 AM EDT), and freshclam correctly downloaded daily 26231 over 26230. Later on, from the same system, main was allegedly (DNS TXT) supposed to be at 60, and daily was supposed to be at 26232, but *both* failed to download at least 7 times (15:43 EDT through 21:43). This may, of course, be essentially the same problem I had with Cloudflare's BOS (Anycast) POP a couple of years ago, which made me give up putting any more work into setting up my own mirror. ___ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
Re: [clamav-users] Freshclam updates problem
Hi Mark, I think I know what happened on your system. The CDN (cloudflare) sometimes sends cached responses for daily.cvd downloads, and presumably also does for main.cvd. If you got a cached main.cvd version 59 after attempting to download version 60, then it would try a new download all over again the next time you run freshclam. We just cleared the cache on cloudflare so hopefully this doesn't happen again. Clearing the cache hasn't been reliable, in my experience, so if we get more reports of this we'll clear it again. Meanwhile, we're building a minor patch version for main.cvd and publish version 61. Combine that with the daily update for daily.cvd and we should be back to normal tomorrow morning.

Re: [clamav-users] Freshclam updates problem
Hi Robert, The zero-byte cdiff update was intentional. For more details, see: https://lists.clamav.net/pipermail/clamav-users/2021-July/011494.html The database back-end folks did the right thing... This error message is my fault and is a Freshclam bug. Thankfully this bug should just be a loud error message but should not cause Freshclam to fail. Freshclam should begin to behave normally again after we publish the next database version and it downloads that. Please see my message from just a bit ago for more details: https://lists.clamav.net/pipermail/clamav-users/2021-July/011499.html Regards, Micah > -Original Message- > From: clamav-users On Behalf Of > Robert M.

Re: [clamav-users] Freshclam updates problem
Hi Paul, all: We're triaging this issue now, also reported by a user on Discord. We issue a zero-byte CDIFF database patch file whenever we want Freshclam to download a whole CVD instead of doing the incremental/patch update. Today we published a zero-byte patch file for both daily and main, as we've migrated about half of the daily signatures over to the main database. Unfortunately it appears we have a bug in 0.102 and 0.103 where Freshclam will complain loudly about the zero-byte CDIFF patch file. I suspect we didn't notice it before because, despite the error message, Freshclam will still do the right thing (at least in 0.102). But it seems 0.103 has a second bug where it will patiently wait until it's at least 2 versions behind before it downloads the whole CVD database. This behavior is supposed to happen when a private mirror doesn't have the latest patch file yet, but wasn't supposed to happen for a zero-byte patch file. So we clearly have 2 bugs to fix ASAP. The good news is, I believe that if we publish 1 more version of daily.cvd and main.cvd, we will see the 0.103 Freshclam clients all download the new daily & main and they'll be good again. I will work with our signature publishing team here to get an update for daily & main out as soon as we're able. I'm sorry about the bug everyone. Thank you for your patience! I will write again a soon as I have an update. -Micah > -Original Message- > From: clamav-users On Behalf Of > Paul Netpresto via clamav-users > Sent: Wednesday, July 14, 2021 3:30 PM > To: clamav-users@lists.clamav.net > Cc: Paul Netpresto > Subject: [clamav-users] Freshclam updates problem > > Hello > > This has started occurring on all our 103.2 systems.

Re: [clamav-users] The "=" sign in freshclam options (---datadir= as an example) is mandatory?
Hi there, On Wed, 14 Jul 2021, Michael Wang wrote: I discovered that the "=" sign in freshclam option is mandatory. For example: freshclam --datadir=c:\temp\database (with =) and freshclam --datadir c:\temp\database (without =) are different. In the latter, the option "--datadir c:\temp\database" is ignored as if it were not specified. On the other hand, the "=" in clamscan option is optional, i.e. clamscan --log=c:\tmp\my.log and clamscan --log c:\tmp\my.log are equivalent. I would like to get a confirmation that this is true, and secondly to get an opinion if this is a bug, as far as I know, the = in option should be optional. If an option takes an argument, and it has long and short forms (for example -l and --log) then it's more or less a Unix custom for the short form of the option to require that there is no following '=', and for the long form to require one. As you say, the clamscan and freshclam 'man' pages show that, but it seems that the conformance of the executables to the custom is patchy. I've confirmed that clamscan on Linux behaves in the same way you have described for Windows. Because of the changes currently taking place in the main and daily databases I haven't run freshclam to test it (in any case I very rarely run freshclam manually) but I'd be surprised if it didn't also behave in the same way. Most of the code is common (in .../shared/optparser.c) to both operating systems. Thesedays, rather than re-invent that particular wheel I'd use a library, but I guess at the time this was written (getting on for twenty years ago) the author had his reasons. I think you've found two faults, not one. Unless the man page says that it will ignore a malformed option, freshclam should not do that; it should issue an error message and quit with no other action. And the '=' should be required, not optional, in the option's long form. I'd recommend reporting the faults via the ClamAV Bugzilla, if they have not already been reported. Full marks for studying the man pages carefully and checking that the binaries behave as described. -- 73, Ged. ___ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
[clamav-users] The "=" sign in freshclam options (---datadir= as an example) is mandatory?
I discovered that the "=" sign in freshclam option is mandatory. For example: freshclam --datadir=c:\temp\database (with =) and freshclam --datadir c:\temp\database (without =) are different. In the latter, the option "--datadir c:\temp\database" is ignored as if it were not specified. On the other hand, the "=" in clamscan option is optional, i.e. clamscan --log=c:\tmp\my.log and clamscan --log c:\tmp\my.log are equivalent. I would like to get a confirmation that this is true, and secondly to get an opinion if this is a bug, as far as I know, the = in option should be optional. ___ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
