In 8a0ea3ee43 we added a
temp_service_list local variable to rend_config_services, but we
didn't add a corresponding "free" for it to all of the exit paths.
Fixes bug 20987; bugfix on 0.3.0.1-alpha.
The new HS circuitmap API replaces old public functions as follows:
circuit_clear_rend_token -> hs_circuitmap_remove_circuit
circuit_get_rendezvous -> hs_circuitmap_get_rend_circ
circuit_get_intro_point -> hs_circuitmap_get_intro_circ_v2
circuit_set_rendezvous_cookie -> hs_circuitmap_register_rend_circ
circuit_set_intro_point_digest -> hs_circuitmap_register_intro_circ_v2
This commit also removes the old rendinfo code that is now unused.
It also fixes the broken rendinfo unittests.
The HS circuitmap is a hash table that maps introduction and rendezvous
tokens to specific circuits such that given a token it's easy to find
the corresponding circuit. It supports rend circuits and v2/v3 intro
circuits.
It will be used by the prop224 ESTABLISH_INTRO code to register and
lookup v3 introduction circuits.
The next commit after this removes the old code and fixes the unittests.
Please consult both commits while reviewing functionality differences
between the old and new code. Let me know if you want this rebased
differently :)
WRT architectural differences, this commit removes the rendinfo pointer
from or_circuit_t. It then adds an hs_token_t pointer and a hashtable
node for the HS circuitmap. IIUC, this adds another pointer to the
weight of or_circuit_t. Let me know if you don't like this, or if you
have suggestions on improving it.
Back when Roger had do do most of our testing on the moria host, we
needed a higher limit for the number of relays running on a single
IP address when that limit was shared with an authority. Nowadays,
the idea is pretty obsolete.
Also remove the router_addr_is_trusted_dir() function, which served
no other purpose.
Closes ticket 20960.
In c35fad2bde, merged in
0.2.4.7-alpha, we removed the code to parse v1 directory
objects. When we did so, we removed everything that could set the
CST_CHECK_AUTHORITY flag for check_signature_token().
So in this code, we remove the flag itself, the code to handle the
flag, and a function that only existed to handle the flag.
Circuit object wasn't freed correctly. Also, the cpath build state object
needed to be zeroed else we were freeing garbage pointers.
Closes#20936
