a7ca71cf6b Fix mock_crypto_pk_public_checksig__nocheck() to handle short RSA keys
This function -- a mock replacement used only for fuzzing -- would
have a buffer overflow if it got an RSA key whose modulus was under
20 bytes long.

Fortunately, Tor itself does not appear to have a bug here.

Fixes bug 24247; bugfix on 0.3.0.3-alpha when fuzzing was
introduced.  Found by OSS-Fuzz; this is OSS-Fuzz issue 4177.

42ce6f78c8 control: Fix wrong Action on failure to upload an HS descriptor
On failure to upload, the HS_DESC event would report "UPLOAD_FAILED" as the
Action but it should have reported "FAILED" according to the spec.

Fixes #24230

0c6eabf088 Audit all of the "is the network turned off" checks.
DisableNetwork is a subset of net_is_disabled(), which is (now) a
subset of should_delay_dir_fetches().

Some of these changes are redundant with others higher or lower in
the call stack.  The ones that I think are behavior-relevant are
listed in the changes file.  I've also added comments in a few
places where the behavior is subtle.

Fixes bug 12062; bugfix on various versions.

40c64f45f0 Re-remove AllowDotExit deprecation.
This was accidentally reintroduced in 5a46074e55.  It should be
harmless, though: the option is obsolete, so calling it deprecated
is redundant.

fa70aabb62 dirauth: Recalculate voting schedule at first vote
Commit e67f4441eb introduced a safeguard against
using an uninitialized voting schedule object. However, the dirvote_act() code
was looking roughly at the same thing to know if it had to compute the timings
before voting with this condition:

  if (!voting_schedule.voting_starts) {
    ...
    dirvote_recalculate_timing(options, now);
  }

The sr_init() function is called very early and goes through the safeguard
thus the voting schedule is always initilized before the first vote.

That first vote is a crucial one because we need to have our voting schedule
aligned to the "now" time we are about to use for voting. Then, the schedule
is updated when we publish our consensus or/and when we set a new consensus.
From that point on, we only want to update the voting schedule through that
code flow.

This "created_on_demand" is indicating that the timings have been recalculated
on demand by another subsystem so if it is flagged, we know that we need to
ignore its values before voting.

Fixes #24186

0dc55fb247 Don't delay descriptor fetches when missing info needed for circuits
When we have fewer than 15 descriptors to fetch, we will delay the
fetch for a little while.  That's fine, if we can go ahead and build
circuits... but if not, it's a poor choice indeed.

Fixes bug 23985; bugfix on 0.1.1.11-alpha.

In 0.3.0.3-alpha, when we made primary guard descriptors necessary
for circuit building, this situation got worse.

3c03e237ab Remove an erroneous 0.5 in compute_weighted_bandwidths()
Back in 0.2.4.3-alpha (e106812a77), when we switched from using
double to using uint64 for selecting by bandwidth, I got the math
wrong: I should have used llround(x), or (uint64_t)(x+0.5), but
instead I wrote llround(x+0.5).  That means we would always round
up, rather than rounding to the closest integer

dcabf801e5 sched: Ignore closed channel after flushing cells
The flush cells process can close a channel if the connection write fails but
still return that it flushed at least one cell. This is due because the error
is not propagated up the call stack so there is no way of knowing if the flush
actually was successful or not.

Because this would require an important refactoring touching multiple
subsystems, this patch is a bandaid to avoid the KIST scheduler to handle
closed channel in its loop.

Bandaid on #23751.
