Add to the Denial of Service section of the man page an explanation about the
three different mitigation Tor has.
Fixes#25248.

In d1874b4339, we adjusted this check so that we insist on
using routerinfos for bridges. That's almost correct... but if we
have a bridge that is also a regular relay, then we should use
insist on its routerinfo when connecting to it as a bridge
(directly), and be willing to use its microdescriptor when
connecting to it elsewhere in our circuits.
This bug is a likely cause of some (all?) of the (exit_ei == NULL)
failures we've been seeing.
Fixes bug 25691; bugfix on 0.3.3.4-alpha
This patch changes the algorithm of compute_real_max_mem_in_queues() to
use 0.4 * RAM iff the system has more than or equal to 8 GB of RAM, but
will continue to use the old value of 0.75 * RAM if the system have less
than * GB of RAM available.
This patch also adds tests for compute_real_max_mem_in_queues().

This one happens if for some reason you start with DirPort enabled
but server mode turned off entirely.
Fixes a case of bug 23693; bugfix on 0.3.1.1-alpha.
This patch lifts the list of default directory authorities from config.c
into their own auth_dirs.inc file, which is then included in config.c
using the C preprocessor.

Both in geoip_note_client_seen() and options_need_geoip_info(), switch from
accessing the options directly to using the should_record_bridge_info() helper
function.

When a relay is collecting internal statistics about how many
create cell requests it has seen of each type, accurately count the
requests from relays that temporarily fall out of the consensus.
(To be extra conservative, we were already ignoring requests from clients
in our counts, and we continue ignoring them here.)
Fixes bug 24910; bugfix on 0.2.4.17-rc.
Directory authorities no longer vote in favor of the Guard flag
for relays that don't advertise directory support.
Starting in Tor 0.3.0.1-alpha, Tor clients have been avoiding using
such relays in the Guard position, leading to increasingly broken load
balancing for the 5%-or-so of Guards that don't advertise directory
support.
Fixes bug 22310; bugfix on 0.3.0.6.
Add a missing lock acquisition around access to queued_control_events
in control_free_all(). Use the reassign-and-unlock strategy as in
queued_events_flush_all(). Fixes bug 25675. Coverity found this bug,
but only after we recently added an access to
flush_queued_event_pending.
The anchor here was originally introduced to make sure that the
manpage would format correctly, but we had mistaken it for a section
anchor, and introduced a bogus section heading in 3563a2c819.
Fixes bug 25582; bugfix on 0.3.3.1-alpha.
Coverity found a null pointer reference in nodelist_add_microdesc().
This is almost certainly impossible assuming that the routerstatus_t
returned by router_get_consensus_status_by_descriptor_digest() always
corresponds to an entry in the nodelist. Fixes bug 25629.

to connect again for another 60 seconds.

This update is needed to make it consistent with the behavior of
node_awaiting_ipv6(), which doesn't believe in the addresses from
routerinfos unless it actually plans to use those routerinfos.
Fixes bug 25213; bugfix on b66b62fb75 in 0.3.3.1-alpha,
which tightened up the definition of node_awaiting_ipv6().
There was a nonfatal assertion in pathbias_should_count that would
trigger if onehop_tunnel was set, but the desired_path_length was
greater than 1. This patch fixes that. Fixes bug 24903; bugfix on
0.2.5.2-alpha.
