The consdiff generation logic would skip over lines added at the start of the
second file, and generate a diff that it would the immediately refuse because
it couldn't be used to reproduce the second file from the first. Fixes #21996.

The reason for making the temporary list public is to keep it encapsulated in
the rendservice subsystem so the prop224 code does not have direct access to
it and can only affect it through the rendservice pruning function.
It also has been modified to not take list as arguments but rather use the
global lists (main and temporary ones) because prop224 code will call it to
actually prune the rendservice's lists. The function does the needed rotation
of pointers between those lists and then prune if needed.
In order to make the unit test work and not completely horrible, there is a
"impl_" version of the function that doesn't free memory, it simply moves
pointers around. It is directly used in the unit test and two setter functions
for those lists' pointer have been added only for unit test.

Now we have separate getters and setters for service-side and relay-side. I
took this approach over adding arguments to the already existing methods to
have more explicit type-checking, and also because some functions would grow
too large and dirty.
This commit also fixes every callsite to use the new function names which
modifies the legacy HS (v2) and the prop224 (v3) code.

One of the goals of this change is to have trunnel API/ABI being more explicit
so we namespace them with "trn_*". Furthermore, we can now create
hs_cells.[ch] without having to confuse it with trunnel which used to be
"hs_cell_*" before that change.
Here are the perl line that were used for this rename:
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/*/*.[ch]
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/trunnel/hs/*.trunnel
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/*/*.[ch]
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/trunnel/hs/*.trunnel
And then "./scripts/codegen/run_trunnel.sh" with trunnel commit id
613fb1b98e58504e2b84ef56b1602b6380629043.

Pinning EntryNodes along with hidden services can be possibly harmful (for
instance #14917 and #21155) so at the very least warn the operator if this is
the case.

Now that base64_decode() checks the destination buffer length against
the actual number of bytes as they're produced, shared_random.c no
longer needs the "SR_COMMIT_LEN+2" workaround.

Some of those defines will be used by the v3 HS protocol so move them to a
common header out of rendservice.c. This is also ground work for prop224
service implementation.

takes specific argument instead of the or_option_t object.

When a client tried to connect to an invalid port of an hidden service, a
warning was printed:
[warn] connection_edge_process_relay_cell (at origin) failed.
This is because the connection subsystem wants to close the circuit because
the port can't be found and then returns a negative reason to achieve that.
However, that specific situation triggered a warning. This commit prevents it
for the specific case of an invalid hidden service port.
Fixes #16706

Add a new helper function route_len_for_purpose(), which explicitly
lists all of the known circuit purposes for a circuit with a chosen
exit node (unlike previously, where the default route length for a
chosen exit was DEFAULT_ROUTE_LEN + 1 except for two purposes). Add a
non-fatal assertion for unhandled purposes that conservatively returns
DEFAULT_ROUTE_LEN + 1.
Add copious comments documenting which circuits need an extra hop and
why.
Thanks to nickm and dgoulet for providing background information.

This makes it so main.c, and the rest of src/or, no longer need to

The old implementation had duplicated code in a bunch of places, and
it interspersed spool-management with resource management. The new
implementation should make it easier to add new resource types and
maintain the spooling code.

When calculating max sampled size, Tor would only count the number of
bridges in torrc, without considering that our state file might already
have sampled bridges in it. This caused problems when people swap
bridges, since the following error would trigger:
[warn] Not expanding the guard sample any further; just hit the
maximum sample threshold of 1

This patch changes the way we decide when to check for whether it's time
to rotate and/or expiry our onion keys. Due to proposal #274 we can now
have the keys rotate at different frequencies than before and we thus
do the check once an hour when our Tor daemon is running in server mode.
This should allow us to quickly notice if the network consensus
parameter have changed while we are running instead of having to wait
until the current parameters timeout value have passed.
See: See: https://bugs.torproject.org/21641

This patch adds a new timer that is executed when it is time to expire
our current set of old onion keys. Because of proposal #274 this can no
longer be assumed to be at the same time we rotate our onion keys since
they will be updated less frequently.

This patch adds an API to get the current grace period, in days, defined
as the consensus parameter "onion-key-grace-period-days".
As per proposal #274 the values for "onion-key-grace-period-days" is a
default value of 7 days, a minimum value of 1 day, and a maximum value
defined by other consensus parameter "onion-key-rotation-days" also
defined in days.
See: https://bugs.torproject.org/21641
|
|
This patch turns `MIN_ONION_KEY_LIFETIME` into a new function
`get_onion_key_lifetime()` which gets its value from a network consensus
parameter named "onion-key-rotation-days". This allows us to tune the
value at a later point in time with no code modifications.
We also bump the default onion key lifetime from 7 to 28 days as per
proposal #274.
