Implement range bans (#478) * Implement range bans People connecting from banned IP ranges are unable to upload torrents anonymously, and need to manually have their accounts activated. This adds a new table "rangebans", and a command line utility, "rangeban.py", which can be used to add, list and remove rangebans from the command line. As an example: ./rangeban.py ban 192.168.0.0/24 This would rangeban anything in this /24. The temporary_tor column allows automated scripts to clean out and re-add ever-changing sets of ranges to be banned without affecting the other ranges. This has only been tested for IPv4. * Revise Rangebans Add an id column, and change "temporary_tor" to "temp". Also index masked_cidr and mask. * rangebans: fix enabled and the binary op kill me * Add enabling/disabling bans to rangeban.py * rangebans: fail earlier on garbage arguments * rangebans: fix linter errors * rangeban.py: don't shadow builtin keyword 'id' * rangebans: change temporary ban logic, column The 'temp' column is now a nullable time column. If the field is null, the ban is understood to be permanent. If there is a time in there, it's understood to be the creation time of the ban. This allows scripts to e.g. delete all temporary bans older than a certain amount of time. Also, rename the '_cidr_string' column to 'cidr_string', because reasons. * rangeban.py: use ip_address to parse CIDR subnet * rangebans: fixes to the mask calculation and query Both were not bugs per-se, but just technically not needed/correct. * De-meme apparently
