When classifying a client's selection of TLS ciphers, if the client
ciphers are not yet available, do not cache the result. Previously,
we had cached the unavailability of the cipher list and never looked
again, which in turn led us to assume that the client only supported
the ancient V1 link protocol. This, in turn, was causing Stem
integration tests to stall in some cases. Fixes bug 30021; bugfix
on 0.2.4.8-alpha.
so that the relays that would be "excluded" from the bandwidth
file because of something failed can be included to diagnose what
failed, without still including these relays in the bandwidth
authorities vote.
Closes#29806.
Allow connections to single onion services to remain idle without being
disconnected.
Relays acting as rendezvous points for single onion services were
mistakenly closing idle established rendezvous circuits after 60 seconds,
thinking that they are unused directory-fetching circuits that had served
their purpose.
Fixes bug 29665; bugfix on 0.2.1.26.
Stop leaking parts of the shared random state in the shared-random unit
tests. The previous fix in 29599 was incomplete.
Fixes bug 29706; bugfix on 0.2.9.1-alpha.
Prior to #23100, we were not counting HS circuit build times in our
calculation of the timeout. This could lead to a condition where our timeout
was set too low, based on non HS circuit build times, and then we would
abandon all HS circuits, storing no valid timeouts in the histogram.
This commit avoids the assert.
KIST works by computing how much should be allowed to write to the kernel for
a given socket, and then it writes that amount to the outbuf.
The problem is that it could be possible that the outbuf already has lots of
data in it from a previous scheduling round (because the kernel is full/busy
and Tor was not able to flush the outbuf yet). KIST ignores that the outbuf
has been filling (is above its "highwater") and writes more anyway. The end
result is that the outbuf length would exceed INT_MAX, hence causing an
assertion error and a corresponding "Bug()" message to get printed to the
logs.
This commit makes it for KIST to take into account the outbuf length when
computing the available space.

malloc_options needs to be declared extern (and declaring it extern
means we need to initialize it separately)
