Longer and more explicit log message so we don't confuse users with behind NAT with working configurations and state that public IP addresses only should be provided with "Address", won't work with internal addresses.
These functions were there so that we could abstract the differences
between evbuffer and buf_t. But with the bufferevent removal, this
no longer serves a purpose.
If we know a node's version, and it can't do ntor, consider it not running.
If we have a node's descriptor, and it doesn't have a valid ntor key,
consider it not running.
Refactor these checks so they're consistent between authorities and clients.
Before, they checked for version 0.2.4.18-rc or later, but this
would not catch relays without version lines, or buggy or malicious
relays missing an ntor key.
This fixes#19608, allowing IPv6-only clients to use
microdescriptors, while preserving the ability of bridge clients
to have some IPv4 bridges and some IPv6 bridges.
Fix on c281c036 in 0.2.8.2-alpha.
I grepped and hand-inspected the "it's" instances, to see if any
were supposed to be possessive. While doing that, I found a
"the the", so I grepped to see if there were any more.
Keep the base16 representation of the RSA identity digest in the commit object
so we can use it without using hex_str() or dynamically encoding it everytime
we need it. It's used extensively in the logs for instance.

This patch also updates a comment in the same function for accuracy.

Only some very ancient distributions don't ship with Libevent 2 anymore,
even the oldest supported Ubuntu LTS version has it. This allows us to
get rid of a lot of compat code.
Our sandboxing code would not allow us to write to stats/hidserv-stats,
causing tor to abort while trying to write stats. This was previously
masked by bug#19556.
When sandboxing is enabled, we could not write any stats to disk.
check_or_create_data_subdir("stats"), which prepares the private stats
directory, calls check_private_dir(), which also opens and not just stats() the
directory. Therefore, we need to also allow open() for the stats dir in our
sandboxing setup.
The *get* state query functions for the SRVs now only return const pointers
and the DEL action needs to be used to delete the SRVs from the state.

This patch makes us retain the intermediate list of K=V entries for
the duration of computing our vote, and lets us use that list with
a new function in order to look up parameters before the consensus
is published.
We can't actually use this function yet because of #19011: our
existing code to do this doesn't actually work, and we'll need a new
consensus method to start using it.
Closes ticket #19012.
Commit and reveal length macro changed from int to unsigned long int

See ticket #19132 for the clang/llvm warning.
Since voting_schedule is a global static struct, it will be initialized
to zero even without explicitly initializing it with {0}.
This is what the C spec says:
If an object that has automatic storage duration is not initialized
explicitly, its value is indeterminate. If an object that has static
storage duration is not initialized explicitly, then:
— if it has pointer type, it is initialized to a null pointer;
— if it has arithmetic type, it is initialized to (positive or unsigned) zero;
— if it is an aggregate, every member is initialized (recursively) according to these rules;
— if it is a union, the first named member is initialized (recursively) according to these rules.
Code has been changed so every RSA fingerprint for a commit in our state is
validated before being used. This fixes the unit tests by mocking one of the
key function and updating the hardcoded state string.

We assert on it using the ASSERT_COMMIT_VALID() macro in critical places

The prop250 code used the RSA identity key fingerprint to index commit in a
digestmap instead of using the digest.
To behavior change except the fact that we are actually using digestmap
