Use the Travis Homebrew addon to install packages on macOS. The package
list is the same, but the Homebrew addon does not do a `brew update` by
default.
This makes builds faster, at the cost of using slightly older packages.
Implements ticket 27738.
This argument was added to match an older idea for the C api, but we
decided not to do it that way in C.
Fixes bug 27741; bugfix on 0.3.3.6 / TROVE-2018-005 fix.
Since the default cache directory is the same as the default data
directory, we don't want the default CacheDirectoryGroupReadable
value (0) to override an explicitly set "DataDirectoryGroupReadable
1".
To fix this, I'm making CacheDirectoryGroupReadable into an
autobool, and having the default (auto) value mean "Use the value of
DataDirectoryGroupReadable if the directories are the same, and 0
otherwise."
Fixes bug 26913; bugfix on 0.3.3.1-alpha when the CacheDirectory
option was introduced.
In hs_config.c, we do validate the permission of the hidden service directory
but we do not try to create it. So, in the event that the directory doesn't
exists, we end up in the loading key code path which checks for the
permission and possibly creates the directory. On failure, don't BUG() since
there is a perfectly valid use case for that function to fail.
Fixes#27335

On GCC and Clang, there's a feature to warn you about bad
conditionals like "if (a = b)", which should be "if (a == b)".
However, they don't warn you if there are extra parentheses around
"a = b".
Unfortunately, the tor_assert() macro and all of its kin have been
passing their inputs through stuff like PREDICT_UNLIKELY(expr) or
PREDICT_UNLIKELY(!(expr)), both of which expand to stuff with more
parentheses around "expr", thus suppressing these warnings.
To fix this, this patch introduces new macros that do not wrap
expr. They're only used when GCC or Clang is enabled (both define
__GNUC__), since they require GCC's "({statement expression})"
syntax extension. They're only used when we're building the
unit-test variant of the object files, since they suppress the
branch-prediction hints.
I've confirmed that tor_assert(), tor_assert_nonfatal(),
tor_assert_nonfatal_once(), BUG(), and IF_BUG_ONCE() all now give
compiler warnings when their argument is an assignment expression.
Fixes bug 27709.
Bugfix on 0.0.6, where we first introduced the "tor_assert()" macro.
.retain() would allocating a Vec of billions of integers and check them
one at a time to separate the supported versions from the unsupported.
This leads to a memory DoS.
Closes ticket 27206. Bugfix on e6625113c9.
Before 0.3.3.1-alpha, we would exit() in this case immediately. But
now that we leave tor_main() more conventionally, we need to make
sure we restore things so as not to cause a double free.
Fixes bug 27708; bugfix on 0.3.3.1-alpha.
It's possible for a unit test to report success via its pipe, but to
fail as it tries to clean up and exit. Notably, this happens on a
leak sanitizer failure.
Fixes bug 27658; bugfix on 0.2.2.4-alpha when tinytest was
introduced.
As of August 29, 2018, Appveyor images come with gcc 8.2.0 by
default. 64-bit Windows executables compiled with gcc 8.2.0 and
tor's --enable-gcc-hardening crash.
Fixes bug 27460; bugfix on 0.3.4.1-alpha.
It is not supported, and always fails. Some compilers warn about the
function pointer cast on 64-bit Windows.
Fixes bug 27461; bugfix on 0.2.2.23-alpha.
gcc 8 warns that extend_info_t.nickname might be truncated by strncpy().
But it doesn't know that nickname can either contain a hex id, or a
nicknames. hex ids are only used for general and HSDir circuits.
Fixes bug 27463; bugfix on 0.1.1.2-alpha.
GetProcAddress() returns FARPROC, which is (long long int(*)()) on
64-bit Windows:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms683212(v=vs.85).aspx
But GetAdaptersAddresses() is (long unsigned int(*)()), on both 32-bit
and 64-bit Windows:
https://docs.microsoft.com/en-us/windows/desktop/api/iphlpapi/nf-iphlpapi-getadaptersaddresses
So gcc 8 issues a spurious "incompatible function pointer" warning
about the cast to GetAdaptersAddresses_fn_t.
Silence this warning by casting to a void function pointer, before
the cast to GetAdaptersAddresses_fn_t.
This issue is already fixed by 26481 in 0.3.5 and later, by removing
the lookup and cast.
Fixes bug 27465; bugfix on 0.2.3.11-alpha.
We allow their CONNECTEDs, RESOLVEDs, ENDs, SENDMEs, and DATA cells to not
count as dropped until the windows are empty, or we get an END.
This commit does not change behavior. It only changes CIRC_BW event field
values.
No behaviour change.
A previous fix to chutney removed v3 onion services from the
mixed+hs-v23 network, so seeing "mixed+hs-v23" in tests is
confusing.
Fixes bug 27345; bugfix on 0.3.2.1-alpha.
LinkAuth method 1 is the one where we pull the TLS master secrets
out of the OpenSSL data structures and authenticate them with
RSA. Right now we list method 1 as required for clients and relays.
That's a problem, since we can't reasonably support it with NSS. So
let's remove it as a requirement and a recommendation.
As for method 3: I'd like to recommend it it, but that would make
0.2.9 start warning. Let's not do that till at least some time
after 0.3.5 (the next LTS) is stable.
Closes ticket 27286
Previously, Tor would only check the exit flag. In small networks, Tor
could bootstrap once it received a consensus with exits, without fetching
the new descriptors for those exits.
After bootstrap, Tor delays descriptor fetches, leading to failures in
fast networks like chutney.
Fixes 27236; bugfix on 0.2.6.3-alpha.
Unlike the old test, this test no will no longer mess around with
the forbidden internals of any openssl data structures.
Additionally, it verifies several other behaviors of
tor_tls_cert_matches_key() that we had wanted to verify, such as
the possibility of the certificate's key not matching.
Fixes bug 27226; bugfix on 0.2.5.1-alpha.
Until https://github.com/rust-lang/rust/issues/52652 is fixed,
unwinding on panic is potentially unsound in a mixed C/Rust codebase.
The codebase is supposed to be panic-free already, but just to be safe.
This started mattering at commit d1820c1516.
Fixes#27199; bugfix on tor-0.3.3.1-alpha.
It's impossible for spaces to get here, since spaces are used as
separators between individual protocol entries higher up.
And it shouldn't ignore whitespace that isn't a literal space
character, because that would differ from the C implementation.
These were added in 9925d2e687.
Fixes#27177. Bugfix on 0.3.3.5-rc.
It was parsing "1-2-3" as if it were 1-2, ignoring the 2nd hyphen
and everything after.

Creating the configure flags once avoids inconsistent flags
between configure and distcheck configure.
Echoing the flags helps developers work out what configure is
doing.

I hope that the debian clang maintainers will look at debian bug

If we're building for Windows, we want to use windows threads no
matter what, and we don't want to link a pthread library even if it
is present. Fixes bug 27081; bugfix on 1790dc6760 in 0.1.0.1-rc.
When we fixed 25939 in f7633c1fca, we
introduced a call to rescan_periodic_events() from inside the onion
service logic. But this meant that we could rescan the event list --
thereby running event callbacks! -- from inside the hidden service code.
This could cause us to run some of our event callbacks from an
inconsistent state, if we were in the middle of changing options.
A related bug (#25761) prevented us from rescanning our periodic
events as appropriate, but when we fixed THAT one, this bug reared
its ugly head.
The fix here is that "enabling" an event should cause us to run it
from the event loop, but not immediately from the point where we
enable it.
Fixes bug 27003; bugfix on 0.3.4.1-alpha.
We would usually call it through tor_cleanup(), but in some code
paths, we wouldn't. These paths would break restart-in-process,
since leaving fields uncleared would cause assertion failures on
restart.

Conditionalize the pragma that temporarily disables
