Add a publish-subscribe subsystem to publish messages about changes to
OR connections.
connection_or_change_state() in connection_or.c and
control_event_or_conn_event() in control.c publish messages to this
subsystem via helper functions.
Move state constants from connection_or.h to orconn_state.h so that
subscribers don't have to include all of connection_or.h to take
actions based on changes in OR connection state. Move event constants
from control.h for similar reasons.
Part of ticket 27167.

Also, turn an absent hostname into a BUG(), not a crash.

Relay side of prop293.

This patch has routers use the same canonicalization logic as
authorities when encoding their family lists. Additionally, they
now warn if any router in their list is given by nickname, since
that's error-prone.
This patch also adds some long-overdue tests for family formatting.
|
|
This will help as we refactor it.

This commit just moves the code to two separate files. The geoip
code still has a few needless dependencies on core/* and features/*.

|
Make them only include the headers that they needed, and sort their
headers while we're at it.
|
|
Since this is completely core functionality, I'm putting it in
core/mainloop, even though it depends on feature/hibernate. We'll
have to sort that out in the future.
|
|
(It turns out that some of the functions in router.h didn't even
exist any more, so I just got to delete their declarations completely.)
|

Note that I haven't separated the headers yet (there's still an

This is preparation for having a routermode.h as well

|
This is also used by onion services, so it needs to go in another
module.

|
Parts of this C file naturally belong in dircache, dirclient, and
dircommon: so, move them there.

The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.

The parts for handling cell formats should be in src/core/or.
The parts for handling onionskin queues should be in src/core/or.
Only the crypto wrapper belongs in src/core/crypto.

In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
|
|
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes

This function was a wrapper around RSA_check_key() in openssl, which
checks for invalid RSA private keys (like those where p or q are
composite, or where d is not the inverse of e, or where n != p*q).
We don't need a function like this in NSS, since unlike OpenSSL, NSS
won't let you import a bogus private key.
I've renamed the function and changed its return type to make it
more reasonable, and added a unit test for trying to read a key
where n != p*q.

The OpenSSL "RSA" object is currently 408 bytes compares to the ASN.1 encoding
which is 140 for a 1024 RSA key.
We save 268 bytes per descriptor (routerinfo_t) *and* microdescriptor
(microdesc_t). Scaling this to 6000 relays, and considering client usually
only have microdescriptors, we save 1.608 MB of RAM which is considerable for
mobile client.
This commit makes it that we keep the RSA onion public key (used for TAP
handshake) in ASN.1 format instead of an OpenSSL RSA object.
Changes is done in both routerinfo_t and microdesc_t.
Closes #27246

Part of #27215, we need to call the ed_key_init_from_file function during
option_validate() which is before the global_options variable is set.
This commit make ed_key_init_from_file() stop using get_options() and instead
now has a or_options_t parameter.
