If crypto_early_init fails, a typo in a return value from tor_init
means that tor_main continues running, rather than returning
an error value.
Fixes bug 16360; bugfix on d3fb846d8c in 0.2.5.2-alpha,
introduced when implementing #4900.
Patch by "teor".
Document use of coverity, clang static analyzer, and clang dynamic
undefined behavior and address sanitizers in doc/HACKING.
Add clang dynamic sanitizer blacklist in
contrib/clang/sanitizer_blacklist.txt to exempt known undefined
behavior. Include detailed usage instructions in this blacklist file.

signing_key can be NULL in ed_key_init_from_file in routerkeys.c.
Discovered by clang 3.7 address sanitizer.
Fix on c03694938e, not in any released version of Tor.
clang 3.7 complains that using a preprocessor directive inside
a macro invocation in test_util_writepid in test_util.c is undefined.
Fix on 79e85313aa on 0.2.7.1-alpha.
Unused variable warnings were still generated under some versions of OpenSSL.
Instead, make sure all variables are used under all versions.
Fix on 496df21c89, not in any released version of tor.
Rend_add_service() frees its argument on failure; no need to free again.
Fixes bug 16228, bugfix on 0.2.7.1-alpha
Found by coverity; this is CID 1301387.
As OpenSSL >= 1.0.0 is now required, ECDHE is now mandatory. The group
has to be validated at runtime, because of RedHat lawyers (P224 support
is entirely missing in the OpenSSL RPM, but P256 is present and is the
default).
Resolves ticket #16140.
When set, this limits the maximum number of simultaneous streams per
rendezvous circuit on the server side of a HS, with further RELAY_BEGIN
cells being silently ignored.
This can be modified via "HiddenServiceMaxStreamsCloseCircuit", which
if set will cause offending rendezvous circuits to be torn down instead.
Addresses part of #16052.
Ephemeral services will be listed in rend_services_list at the end of
rend_config_services, so it must check whether directory is non-NULL
before comparing.
This crash happens when reloading config on a tor with mixed configured
and ephemeral services.
Fixes bug #16060. Bugfix on 0.2.7.1-alpha.
For FAILED and RECEIVED action of the HS_DESC event, we now sends back the
descriptor ID at the end like specified in the control-spec section 4.1.25.
Fixes#15881
Signed-off-by: David Goulet <dgoulet@ev0ke.net>
The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.
Fixed by checking auth_len before comparing the descriptor cookie
against known clients.
Fixes#15823; bugfix on 0.2.1.6-alpha.
"+HSPOST" and the related event changes allow the uploading of HS
descriptors via the control port, and more comprehensive event
monitoring of HS descriptor upload status.
