We are excited to announce the ClamAV 1.0.0 release candidate!
I'm seeing log entries like this for the machines with 1.0.0-rc
indicating the daily.cld update failed:
I experienced same problem while I'm working to update FreeBSD ClamAV
port to 1.0.0-rc. It happens if ClamAV is built with external
TomsFastMath library (that is, ENABLE_EXTERNAL_TOMSFASTMATH option is
ON).
See issue #736 for more detail.
https://github.com/Cisco-Talos/clamav/issues/736
I am building from the tarball at
https://www.clamav.net/downloads/production/clamav-1.0.0-rc.tar.gz
on Ubuntu kinetic 22.10 (released this month) and have the same problem,
but have not (yet?) managed to resolve it with the internal TomsFastMath
library.
I started by copying the database directory from one built by freshclam v103.7
which has had no problems with recent updates, including yesterday and today.
The freshclam.conf files have different UpdateLogFile and DatabaseDirectory but
are otherwise identical, including
DatabaseMirror db.local.clamav.net
DatabaseMirror database.clamav.net
Yesterday freshclam suggested that I checked again later, but today
it is downloading the .cvd after failing to patch the .cld
Should I, or you, be concerned that after just two days, freshclam
switches to a large download ?
Joel asked:
You wouldn’t download the cld from the server.
Or am I reading this thread wrong.
No, but the database directory has an existing .cld to update.
In mkdir_and_chdir_for_cdiff_tmp() libfreshclam_internal.c I see:
/*
* 3) Unpack the existing CVD/CLD database to this directory.
*/
if (CL_SUCCESS != cl_cvdunpack(cvdfile, tmpdir, false)) {
logg(LOGG_ERROR, "mkdir_and_chdir_for_cdiff_tmp: Can't unpack %s into
%s\n", cvdfile, tmpdir);
cli_rmdirs(tmpdir);
goto done;
}
but chasing cl_cvdunpack, the verify routines only mention cvd.
Do they verify .cld files too, or is that the real problem ?
------------------------------------
(Whilst the .cvd downloads, the line
Time: 21.7s, ETA: 0.0s [========================>]
57.34MiB/57.34MiB
flickers a lot; does it need to redraw every 0.1 seconds ?)
