2021-10-04net: Reject invalid characters in port rangesc
Fixes issue #22469 where port strings such as '0x00' get accepted, not because the string gets converted to hex, but because the string is silently truncated past the invalid character 'x'. This also causes issues for strings such as '0x01-0x02' which look like a hex port range, but in reality gets truncated to '0', which is definitely not what a user intends. Warn and reject such port strings as invalid. Also, since we're throwing that "malformed port" warning a lot in the function, wrap it up in a nice goto. Fixes #22469

Typos found with codespell. Please keep in mind that this should have impact on actual code and must be carefully evaluated: src/core/or/lttng_circuit.inc - ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER) + ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)

2020-07-29Remove the connection_t.outbuf_flushlen fieldNick Mathewson
This was once used for rate-limiting, but now it's only for accounting. It hasn't served a useful purpose in a long time. Closes ticket 33097.

2020-07-14addr: Use tor_addr_t instead of uint32_t for IPv4David Goulet
This changes a LOT of code but in the end, behavior is the same. Unfortunately, many functions had to be changed to accomodate but in majority of cases, to become simpler. Functions are also removed specifically those that were there to convert an IPv4 as a host format to a tor_addr_t. Those are not needed anymore. The IPv4 address field has been standardized to "ipv4_addr", the ORPort to "ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport". This is related to Sponsor 55 work that adds IPv6 support for relays and this work is needed in order to have a common interface between IPv4 and IPv6. Closes #40043.
