Pyzor crashes with PermissionError on Fedora 43

[vmario89]

Hi,

since OS upgrade my pyzor instance always crashes when getting called by amavis. I got into the backtrace by "abrt-cli" tool and it says

pyzor:101:load_configuration:PermissionError: [Errno 1] Operation not permitted
Traceback (most recent call last):
  File "/usr/local/sbin/pyzor", line 436, in <module>
    main()
~^^
  File "/usr/local/sbin/pyzor", line 135, in main
    config, options, args = load_configuration()
                            ~~~~~~~~~~~~~~~~~~^^
  File "/usr/local/sbin/pyzor", line 101, in load_configuration
    os.nice(options.nice)
    ~~~~~~~^^^^^^^^^^^^^^
PermissionError: [Errno 1] Operation not permitted
Local variables in innermost frame:
userhome: '/var/spool/amavisd'
homedir: '/var/spool/amavisd/.pyzor'
defaults: {'ServersFile': 'servers', 'AccountsFile': 'accounts', 'LocalWhitelist': 'whitelist', 'LogFile': '', 'Timeout': '5', 'Style': 'msg', 'ReportThreshold': '0', 'WhitelistThreshold': '0'}
description: "Read data from stdin and execute the requested command (one of 'check', 'report', 'ping', 'pong', 'digest', 'predigest', 'genkey', 'local_whitelist', 'local_unwhitelist')."
opt: <optparse.OptionParser object at 0x7f880041e510>
options: <Values at 0x7f880041e900: {'nice': 0, 'debug': False, 'homedir': '/var/spool/amavisd/.pyzor', 'Style': None, 'LogFile': None, 'ServersFile': None, 'AccountsFile': None, 'LocalWhitelist': None, 'Timeout': None, 'ReportThreshold': None, 'WhitelistThreshold': None, 'version': False}>
args: ['check']

so the catch statement does not except PermissionError here.

sadly i have no idea how to fix this. The avamis user is able to run /usr/local/sbin/pyzor check with any trouble (checked this manually). There is also exactly zero error line in the SELinux log file

the user of /var/spool/amavisd/.pyzor is avamis and this looks good

my fix for now is to disable the lines around os.nice(options.nice) but i prefer a real fix and to understand the root cause.

any idea?

thanks, Mario
