In our code to write public keys to a string, for some unfathomable
reason since 253f0f160e, we would allocate a memory BIO, then
set the NOCLOSE flag on it, extract its memory buffer, and free it.
Then a little while later we'd free the memory buffer with
BUF_MEM_free().
As of openssl 1.1 this doesn't work any more, since there is now a
BIO_BUF_MEM structure that wraps the BUF_MEM structure. This
BIO_BUF_MEM doesn't get freed in our code.
So, we had a memory leak!
Is this an openssl bug? Maybe. But our code was already pretty
silly. Why mess around with the NOCLOSE flag here when we can just
keep the BIO object around until we don't need the buffer any more?
Fixes bug 20553; bugfix on 0.0.2pre8
passthrough_test_setup doesn't pass through arguments if the argument
is equal to 0 or TT_SKIP. Instead, it fails or skips the test.
Assert on this, so we don't accidentally fail or skip tests.
Fixes bug 19969; bugfix on b1d56fc58. We can fix this some more in
later Tors, but for now, this is probably the simplest fix possible.
This is a belt-and-suspenders fix, where the earlier fix ("Ask
event_base_loop to finish when we add a pending stream") aims to respond
to new streams as soon as they arrive, and this one aims to make sure
that we definitely respond to all of the streams.
ome policies are default-reject, some default-accept. But
policy_is_reject_star() assumed they were all default_reject. Fix
that!
Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.
Fxes bug 20306; bugfix on 0.2.8.2-alpha.
(Also, refactor the code to create a hidden service directory into a
separate funcion, so we don't have to duplicate it.)
Fixes bug 20484; bugfix on 0.2.9.3-alpha.
This simplifies the function: if we have an ntor key, use ntor/EXTEND2,
otherwise, use TAP/EXTEND.
Bugfix on commit 10aa913 from 19163 in 0.2.9.3-alpha.
The tor_fragile_assert() bug has existed here since c8a5e2d588
in tor-0.2.1.7-alpha forever, but tor_fragile_assert() was mostly a
no-op until 0.2.9.1-alpha.
Fixes bug 19869.
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.
It also closes TROVE-2016-10-001 (aka bug 20384).
