Invalid UTF-8 passed to g_io_channel_write_chars() error in 21-

[wneessen]

I just updated OpenVAS to 21.4.0. Updated all components. GVMd starts fine and gvmd -m migrated the database successfully to version 242. When I now start ospd-openvas, the Python script fails with the error described in greenbone/ospd-openvas#341. So I upgraded gvm-libs to the latest git branch. I rebuilt gmvd and openvas-scaner (still the 21.4.0 versions) as well. Now when I start ospd-openvas, the openvas-scanner seems to core dump.

Expected behavior

osdp-openvas executes openvas-scanner as normally

Actual behavior

ospd-openvas fails with an openvas-scanner error:

The error is actually reproducable by just running the openvas command:

$ openvas
(process:15711): GLib-WARNING (recursed) **: Invalid UTF-8 passed to g_io_channel_write_chars().Aborted (core dumped)
$ openvas
(process:15719): GLib-WARNING (recursed) **: Invalid UTF-8 passed to g_io_channel_write_chars().Aborted (core dumped)
$ openvas
(process:15726): GLib-WARNING (recursed) **: Invalid UTF-8 passed to g_io_channel_write_chars().Aborted (core dumped)

Every now and then, it also throws a different error:

$ openvas
double free or corruption (fasttop)
Aborted (core dumped)

Steps to reproduce

Used OS: Arch Linux (rolling)

1. Download sources for 21.4.0
2. Download the latest gvm-lib sources from git
3. Build everything and install it
4. Run gvmd -m to migrate the database to 242
5. Execute ospd-openvas (or openvas directly)
6. It will core dump with different errors

Hi @wneessen !
Thanks for reporting this issue. I was able to reproduce it. It seems you have something wrong in your redis-server setup, or there is no redis instance running at all.
To reproduce it, I have just changed the permission on the redis socket.

$ ls -la /tmp/redis.sock 
srwxrwx--- 1 juan juan 0 May 14 02:15 /tmp/redis.sock
$ chmod 700 /tmp/redis.sock 
$ sudo chown redis:redis /tmp/redis.sock 
$ openvas

(process:2358): GLib-WARNING (recursed) **: Invalid UTF-8 passed to g_io_channel_write_chars().Aborted

I will fix this soon. Thanks again!

Best Regards,
Juan
