2020-06-24addr: Refactor is_local_addr() to support IPv6David Goulet
Series of changes: 1. Rename function to reflect the namespace of the file. 2. Use the new last resolved cache instead of the unused last_resolved_addr_v4 (which is also removed in this commit). 3. Make the entire code base use the new resolved_addr_is_local() function. You will notice that this function uses /24 to differentiate subnets where the rest of tor uses /16 (including documentation of EnforceDistinctSubnets). Ticket #40009 has been opened for that. But that the moment, the function keeps looking at /24. Part of #33233 Signed-off-by: David Goulet <dgoulet@torproject.org>
2020-06-24addr: Refactor last resolved address cache accessorsDavid Goulet
Series of things done in this commit: 1. Rename the functions to better reflect the namespace of the file. 2. Make both reset and get function to operate on the last_resolved_addrs cache that is per family. 3. Make the get function to take a tor_addr_t. 4. Change all callsite to use the new convention.

2020-06-24addr: Make resolve_my_address_v4() use find_my_address()David Goulet
In order to transition smoothly, maek resolve_my_address_v4() call the new fancy find_my_address() with AF_INET. Next commits should remove the use of resolve_my_address_v4() accross the code to use find_my_address(). This commit is so the unit tests would be more easily fixed and port to the new find_my_address() internals. Part of #33233. Signed-off-by: David Goulet <dgoulet@torproject.org>
2020-06-24addr: New find_my_address() to support multiple address familiesDavid Goulet
resolve_my_address() was beyond repair in terms of refactoring. Way too complex and doing too many things. This commit implements find_my_address() which in theory does the same as resolve_my_address() but in a more clean, concise and modern way using the tor_addr_t interface and for multiple address family. The caller needs to pass the address family (IPv4 or IPv6) which this interface supports. For both, a last resolved cache is used as well. Implements #33233 Signed-off-by: David Goulet <dgoulet@torproject.org>

2020-06-23config: Change Address to be a LINELISTDavid Goulet
With prop312, we want to support IPv4 and IPv6 thus multiple Address statement (up to 2) will be accepted. For this, "Address" option becomes a LINELIST so we can properly process the IPv4 or/and IPv6. Part of #33233 Signed-off-by: David Goulet <dgoulet@torproject.org>

2020-06-17Update the list of recommended protocol versions to match >=0.3.5.Nick Mathewson
Since Tor 0.2.9 has been unsupported since January, 0.3.5 is the oldest supported version, and its features constitute the oldest recommended feature-set. This patch updates these recommendations: DirCache=2 Support for consensus diffs. New in 0.3.1.1-alpha. HSDir=2 Support for v3 onion service descriptors. New in 0.3.0.4-alpha. HSIntro=4 Support for Ed25519 intropoint authentication keys. New in 0.3.0-4-alpha. HSRend=2 Support for rendezvous cells longer than 20 bytes. New in 0.2.9.4-alpha. Link=5 Link padding and link padding negotiation. New in 0.3.3.2-alpha. LinkAuth=3 Ed25519 link authentication. New in 0.3.0.1-alpha.

2020-06-10Bug 30992: Track a padding machine ctr to reduce race issues.Mike Perry
This tracking of the instantiation count should eliminate race conditions due to starting and stopping machines rapidly. Now, we should no longer obey STOP commands for previous machines.

Per ticket #32888 this should address logging "the Address torrc option", "and whether it is an IP address, or a DNS name"; or the detected "local hostname", "and whether it is an IP address, or a DNS name". Some of these details already seem to be logged, so just add what's missing.
2020-05-30Preemptive circs should work with UseEntryGuards 0Roger Dingledine
Resume being willing to use preemptively-built circuits when UseEntryGuards is set to 0. We accidentally disabled this feature with that config setting (in our fix for #24469), leading to slower load times. Fixes bug 34303; bugfix on 0.3.3.2-alpha.
