Coverity doesn't like it when there are paths to the end of the
function where something doesn't get freed, even when those paths
are only reachable on unit test failure.
Fixes CID 1372899 and CID 1372900. Bug not in any released Tor.
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.
Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.
The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).
This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.
When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).
Improve the messages logged when Tor wants or needs to load the master ed25519 identity key so the user is explicitly informed when further action is required or not. Fixes ticket #20650.
Apple is supposed to decorate their function declarations with
macros to indicate which OSX version introduced them, so that you
can tell the compiler that you want to build against certain
versions of OSX. But they forgot to do that for clock_gettime() and
getentropy(), both of which they introduced in 10.12.
This patch adds a kludge to the configure.ac script where, if we
detect that we are targeting OSX 10.11 or earlier, we don't even probe
to see if the two offending functions are present.
Closes ticket 20235.
(We only create HS directories if we are acting on the config.)
Log a BUG warning if the directories aren't present immediately before they
are used, then fail.
For relays that don't know their own address, avoid attempting
a local hostname resolve for each descriptor we download. Also cut
down on the number of "Success: chose address 'x.x.x.x'" log lines.
Fixes bugs 20423 and 20610; bugfix on 0.2.8.1-alpha.
