rendezvous
Services can keep rendezvous circuits for a while so don't log them if tor is
a single onion service.

The HT_FOREACH() is insanely heavy on the CPU and this is part of the fast
path so make it return the nice memory size counter we added in
4d812e29b9b1ec88.

This is needed so llvm_fuzz will see it too.

Becasue the circuit creation burst and rate can change at runtime it is
possible that between two refill of a bucket, we end up setting the bucket
value to less than there currently is.

These functions protect againts over and underflow. They BUG() in case we
overflow the counter.

If the cache is using 20% of our maximum allowed memory, clean 10% of it. Same
behavior as the HS descriptor cache.

The current code flow makes it that we can release a channel in a PENDING
state but not in the pending list. This happens while the channel is being
processed in the scheduler loop.

This tests many cases of the KIST scheduler with the pending list state by
calling entry point in the scheduler while channels are scheduled or not.
Also, it adds a test for the bug #24700.

Included crypto_rsa.[ch] into include.am in order to resolve a compiling issue.
Follows #24658.

crypto_get_rsa_padding_overhead() and crypto_get_rsa_padding() are
not static inline anymore in order to split the crypto_rsa module
from crypto.[ch].
Also included necessary modules in order to solve dependency issues.
Also made two functions in crypto.c use crypto_pk_asn1_encdoe()
instead of reaching into the crypto_pk_t struct.
|
|
OpenSSL never uses these callbacks anymore so the code is disabled.
Fixes #25097.

This reverts commit 9a06282546418b2e9d21559d4853bcf124b953f4.
It appears that I misunderstood how the seccomp2 filter rules
interact. It appears that `SCMP_ACT_ERRNO()` always takes
precedence over `SCMP_ACT_ALLOW()` -- I had thought instead that
earlier rules would override later ones. But this change caused bug
25115 (not in any released Tor).

The accurate address of a connection is real_addr, not the addr member.
channel_tls_get_remote_addr_method() now returns real_addr instead.
Fixes #24952; bugfix on 707c1e2 in 0.2.4.11-alpha.

Tor preemptiely builds circuits and they can be cannibalized later in their
lifetime. A Guard node can become unusable (from our guard state) but we can
still have circuits using that node opened. It is important to not pick those
circuits for any usage through the cannibalization process.

"ours" merge to avoid backport of #25105
|
|
|
|
|

In 0.3.2.1-alpha, we've added notify_networkstatus_changed() in order to have
a way to notify other subsystems that the consensus just changed. The old and
new consensus are passed to it.
Before this patch, this was done _before_ the new consensus was set globally
(thus NOT accessible by getting the latest consensus). The scheduler
notification was assuming that it was set and select_scheduler() is looking at
the latest consensus to get the parameters it might needs. This was very wrong
because at that point it is still the old consensus set globally.
This commit changes the notify_networkstatus_changed() to be the "before"
function and adds an "after" notification from which the scheduler subsystem
is notified.
Fixes #24975

Fixes bug 25105; bugfix on 0.3.2.1-alpha.
(This is a backport of bbf2d9cf6bb97c3e15ada58 for 0.3.2.)

When we stopped looking at the "protocols" variable directly, we
broke the hs_service/build_update_descriptors test, since it didn't
actually update any of the flags.
The fix here is to call summarize_protover_flags() from that test,
and to expose summarize_protover_flags() as "STATIC" from
routerparse.c.
