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.
When "auto" was used for the port number for a listening socket, the
message logged after opening the socket would incorrectly say port 0
instead of the actual port used.

Fixes bug 29530, where the LOG_ERR messages were occurring when
we had no configured network, and so we were failing the unit tests
because of the recently-merged #28668.
Commit message edited by teor:
We backported 28668 and released it in 0.3.5.8.
This commit backports 29530 to 0.3.5.
Fixes bug 29530 in Tor 0.3.5.8.
When IPv4Only (IPv6Only) was used but the address could not be
interpreted as a IPv4 (IPv6) address, the error message referred
to the wrong IP version.
This also fixes up the error-checking logic so it's more precise
about what's being checked.

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.
Bug found and patch by Rob Jansen.

Because the test is adding entries to the "rend_cache" directly, the
rend_cache_increment_allocation() was never called which made the
rend_cache_clean() call trigger that underflow warning:

The code checked for sysctl being available and HW_PHYSMEM being
defined, but HW_USERMEM was actually being used with sysctl instead
of HW_PHYSMEM.
The case for OpenBSD, etc. use HW_PHYSMEM64 (which is obviously a
64-bit variant of HW_PHYSMEM) and the case for OSX uses HW_MEMSIZE
(which appears to be a 64-bit variant of HW_PHYSMEM).

We log these messages at INFO level, except when we are reading a

This fixes a regression from when we re-wrote our PEM code to be
generic between nss and openssl.

Prior to this commit, the testsuite was failing on OpenBSD. After
this commit the testsuite runs fine on OpenBSD.
It was previously decided to test for the OpenBSD macro (rather than
__OpenBSD__, etc.) because OpenBSD forks seem to have the former
macro defined. sys/param.h must be included for the OpenBSD macro
definition; however, many files tested for the OpenBSD macro without
having this header included.
This commit includes sys/param.h in the files where the OpenBSD macro
is used (and sys/param.h is not already included), and it also
changes some instances of the __OpenBSD__ macro to OpenBSD.
See commit 27df23abb6 which changed
everything to use OpenBSD instead of __OpenBSD__ or OPENBSD. See
also tickets #6982 and #20980 (the latter ticket is where it was
decided to use the OpenBSD macro).

In theory it would be better to detect this bug in advance, but this
approach is much simpler, and therefore safer to backport.
This closes tor issue 28973.
Linked connections aren't woken up by libevent due to I/O but rather
artificially so we can, by chunks, empty the spooled object(s).
Commit 5719dfb48f (in 0.3.4.1-alpha) made it
that the schedule_active_linked_connections_event would be only called once at
startup but this is wrong because then we would never go through again the
active linked connections.
Fortunately, everytime a new linked connection is created, the event is
activated and thus we would go through the active list again. On a busy relay,
this issue is mitigated by that but on a slower relays or bridge, a connection
could get stuck for a while until a new directory information request would
show up.
Fixes#28717, #28912
The point of this function is to make sure that the ed25519-based
implementation of curve25519_basepoint() actually works when we
start tor, and use the regular fallback implementation if it
doesn't. But it accounts for 9% of our startup time in the case
when we have directory information, and I think it's safe to make
the test shorter. After all, it has yet to find any actual bugs in
curved25519_scalarmult_basepoint_donna() on any platforms.

When retrying all SOCKS connection because new directory information just
arrived, do not BUG() if a connection in state AP_CONN_STATE_RENDDESC_WAIT is
found to have a usable descriptor.
There is a rare case when this can happen as detailed in #28669 so the right
thing to do is put that connection back in circuit wait state so the
descriptor can be retried.

The transition for a connection to either become or go back in
AP_CONN_STATE_RENDDESC_WAIT state must make sure that the entry connection is
_not_ in the waiting for circuit list.
This commit implements the helper function
connection_ap_mark_as_waiting_for_renddesc() that removes the entry connection
from the pending list and then change its state. This code pattern is used in
many places in the code where next commit will remove this code duplication to
use this new helper function.

In conn_close_if_marked(), we can decide to keep a connection open that still
has data to flush on the wire if it is being rate limited on the write side.
However, in this process, we were also looking at the read() side which can
still have token in its bucket and thus not stop the reading. This lead to a
BUG() introduced in 0.3.4.1-alpha that was expecting the read side to be
closed due to the rate limit but which only applies on the write side.
This commit removes any bandwidth check on the read side and simply stop the
read side on the connection regardless of the bucket state. If we keep the
connection open to flush it out before close, we should not read anything.
