2016-06-11Use autoconf, not gcc version, to decide which warnings we haveNick Mathewson
This gives more accurate results under Clang, which can only help us detect more warnings in more places. Fixes bug 19216; bugfix on 0.2.0.1-alpha
2016-06-11Enable -Woverlength-strings for GCC>=4.6 on MOST of the code.Nick Mathewson
IMO it's fine for us to make exceptions to this rule in the unit tests, but not in the code at large.
2016-06-11Use -Wdouble-promotion in GCC >= 4.6Nick Mathewson
This warning triggers on silently promoting a float to a double. In our code, it's just a sign that somebody used a float by mistake, since we always prefer double.
2016-06-11Add -Wfloat-conversion for GCC >= 4.9Nick Mathewson
This caught quite a few minor issues in our unit tests and elsewhere in our code.
2016-06-11Enable -Wnull-dereference (GCC >=6.1), and fix the easy casesNick Mathewson
This warning, IIUC, means that the compiler doesn't like it when it sees a NULL check _after_ we've already dereferenced the variable. In such cases, it considers itself free to eliminate the NULL check. There are a couple of tricky cases: One was the case related to the fact that tor_addr_to_in6() can return NULL if it gets a non-AF_INET6 address. The fix was to create a variant which asserts on the address type, and never returns NULL.

2016-05-24Make sure that libscrypt_scrypt actually exists before using it.Nick Mathewson
Previously, if the header was present, we'd proceed even if the function wasn't there. Easy fix for bug 19161. A better fix would involve trying harder to find libscrypt_scrypt.
2016-05-20Prevent ASAN from registering a SIGSEGV handlercypherpunks
AddressSanitizer's (ASAN) SIGSEGV handler overrides the backtrace handler and prevents it from printing its backtrace. The output of ASAN is different from what 'bt_test.py' expects and causes backtrace test failures. The 'allow_user_segv_handler' option allows applications to set their own SIGSEGV handler but is not supported by older GCC versions. These older GCC versions do support the 'handle_segv' which prevents ASAN from setting its SIGSEGV handler.

2016-05-17Remove duplicate siging_key_cert fields.Nick Mathewson
With the fix for #17150, I added a duplicate certificate here. Here I remove the original location in 0.2.8. (I wouldn't want to do that in 027, due to the amount of authority-voting-related code drift.) Closes 19073.

This is a whitespace only, cosmetic fix. There is still some inconsistency between lists, but less inconsistency inside individual lists.

requires bugs. Fixes bug 18901.
2016-05-12Refactor out u64_dbl_tNick Mathewson
This type saved a tiny amount of allocation, but not enough to be worth keeping. (This is in preparation for moving choose_array_element_by_weight)
2016-05-12Add -ftrapv to gcc-hardening ... mostly!Nick Mathewson
We know there are overflows in curve25519-donna-c32, so we'll have to have that one be fwrapv. Only apply the asan, ubsan, and trapv options to the code that does not need to run in constant time. Those options introduce branches to the code they instrument. (These introduced branches should never actually be taken, so it might _still_ be constant time after all, but branch predictors are complicated enough that I'm not really confident here. Let's aim for safety.) Closes 17983.

2016-05-11Basic work on a publish/subscribe abstractionNick Mathewson
The goal here is to provide a way to decouple pieces of the code that want to learn "when something happens" from those that realize that it has happened. The implementation here consists of a generic backend, plus a set of macros to define and implement a set of type-safe frontends.
