This should be "impossible" without making a SHA1 collision, but
let's not keep the assumption that SHA1 collisions are super-hard.
This prevents another case related to 21278. There should be no
behavioral change unless -ftrapv is on.
I think this one probably can't underflow, since the input ranges
are small. But let's not tempt fate.
This patch also replaces the "cmp" functions here with just "eq"
functions, since nothing actually checked for anything besides 0 and
nonzero.
Related to 21278.
Fix for TROVE-2017-001 and bug 21278.
(Note: Instead of handling signed ints "correctly", we keep the old
behavior, except for the part where we would crash with -ftrapv.)
This is a purely cosmetic patch that changes RELAY_BEGINDIR in various
comments to RELAY_BEGIN_DIR, which should make it easier to grep for the
symbols.
According to 21116, it seems to be needed for Wheezy Raspbian build. Also,
manpage of socket(2) does confirm that this errno value should be catched as
well in case of no support from the OS of IPv4 or/and IPv6.

This patch ensures that we log the size of the inbuf when a directory
client have reached EOF on the connection.
See: https://bugs.torproject.org/21206
This patch makes the log-statements in `connection_dir_client_reached_eof`
more explicit by writing "body size" instead of just "size" which could
be confused as being the size of the entire response, which would
include HTTP status-line and headers.

This reverts commit 5446cb8d3d.
The underlying revert was done in 0.2.6, since we aren't backporting
seccomp2 loosening fixes to 0.2.6. But the fix (for 17354) already
went out in 0.2.7.4-rc, so we shouldn't revert it in 0.2.7.
This patch adds a debug log statement when sending a request to a
directory server. The information logged includes: the payload size (if
available), the total size of the request, the address and port of the
directory server, and the purpose of the directory connection.

maint-0.2.7-redux is an attempt to try to re-create a plausible
maint-0.2.7 branch. I've started from the tor-0.2.7.6, and then I
merged maint-0.2.6 into the branch.
This has produced 2 conflicts: one related to the
rendcommon->rendcache move, and one to the authority refactoring.
