Pkg - need to re-create database -> Segmentation fault

jimp

It's unusual for that process to segfault the way it did in your case. It makes me wonder if there might be some other corruption in the filesystem, though usually I'd expect that to panic not just segfault. If you can handle a few minutes of downtime, consider booting into single user mode and running "fsck -y /" a few times until fsck no longer finds anything, might take 3-4 passes, but you probably already know how quirky fsck can be with ufs. :-)

The last time we saw "Repository pfSense-core load error" come up, it was because it had trouble verifying the signature on the repository, but that doesn't quite look like what is happening here. It's possible, but unlikely.

Is there something between this firewall and the Internet in general that might be interfering with its DNS responses and/or HTTP/HTTPS connections?

Hi Dan,

I suspect I know what is causing that. Can you please run 'truss pkg update -f' and send me the result?

The pfSense box is connected to a cable modem, and from there to the world. The cable modem is in bridge mode.

The DNS servers are localhost and two DNS servers in-house.

Hi Dan,

It's exactly what I suspected. There is a bug in pkg that causes this crash. You can see details here:

https://github.com/freebsd/pkg/pull/1586

We already fixed it in pfSense before submit the patch to upstream, and based on truss output we can see:


openat(AT_FDCWD,"/usr/local/share/pfSense/keys/pkg/revoked/.empty",O_RDONLY,00) = 8 (0x8)
fstat(8,{ mode=-rw-r–r-- ,inode=140382,size=0,blksize=4096 }) = 0 (0x0)
close(8)					 = 0 (0x0)
SIGNAL 11 (SIGSEGV)
process killed, signal = 11 (core dumped)

The presence of the empty file /usr/local/share/pfSense/keys/pkg/revoked/.empty is the cause. I suspect there is a /usr/local/share/pfSense/keys/pkg/trusted/.empty file too. Just remove them and it will work as expected. As soon as you update pkg to latest version bug will be fixed.

dvl

One file is there. I have removed it.

Do you have key files in /usr/local/share/pfSense/keys/pkg/trusted/?

You should have, for example, pkg.pfsense.org.20160406 and beta.pfsense.org.20151223 in there.

CE is community edition, I'm guessing.

pfSense was installed when I got this box (Netgate APU2).

Does that answer?

Yes, CE is community edition.

If you are using Netgate hardware you are supposed to be running factory. Now the question is how the CE key ended up on your system. Did you install any package manually? changed anything while testing?

Yes, I know I installed at least one package (bacula-client) from my own repo. I know that was September 2016 because it was during EuroBSDCon.

Later, I recall some pkg update which drew down from my repo. That messed stuff up, so I went to a backup to restore service.
