2020-05-12build: multiprocess autotools changesRussell Yanofsky
autoconf and automake changes to support multiprocess gui/node/wallet execution. This adds a new --enable-multiprocess flag, and build configuration code to detect libraries needed for multiprocess support. The --enable-multiprocess flag builds new bitcoin-node and bitcoin-gui executables, which are updated in https://github.com/bitcoin/bitcoin/pull/10102 to communicate across processes. But for now they are functionally equivalent to existing bitcoind and bitcoin-qt executables.

1e94a2bcbc5ff8ae61eed9f31317ea534649116d depends: Add --sysroot option to mac os native compile flags (Russell Yanofsky) Pull request description: Catalina SDK clang stopped automatically searching the SDK include paths when invoked without `--sysroot`: - https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-594600985 - https://github.com/Homebrew/homebrew-core/issues/45061 This hasn't been a problem for current native depends packages because are passing their own `--sysroot` values, and hasn't been a problem for current host packages because they use `darwin_` commands instead of `build_darwin_` commands. But the current `build_darwin_CC` and `build_darwin_CXX` commands are still unnecessarily fragile, and incompatible with new native depends packages added in https://github.com/bitcoin/bitcoin/pull/18677. Cory Fields (theuni) suggested in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-595393546 switching compiler from SDK clang to native clang (from $PATH) to avoid this problem. This is easy and makes a certain amount of sense for building native packages, as opposed to host packages. But Michael (fanquake) pointed out in https://github.com/bitcoin/bitcoin/pull/18677#discussion_r409934309 that it would be inconsistent to switch to non-SDK compilers while still using other SDK tools like `ranlib` and `install_name_tool`. So simplest, minimal fix seems to be just adding the missing `--sysroot` option.

fa082d0a57afedca9122fac4aecd6a3070f06b04 travis: Remove valgrind (MarcoFalke) Pull request description: When the valgrind run was added, it took 2 hours. Travis kindly raised the timeout limit to the maximum possible of 3 hours. Today, a full build of Bitcoin Core with all tests takes more than three hours. Thus, it is impossible to run all tests on travis. Moreover, the feedback loop for developers that create a pull request takes at least 2 hours, but in some cases (when the travis queue is full) until the next day. This is unacceptable. Fix both issues by removing the build from travis. Please note that the `ci/test/` configurations are *not* removed. They will stay in the repo and can be executed anywhere (just not on travis).

a029805f57fa9a4ab9867c0d1e865675d57537c7 build: remove -Qunused-arguments workaround for clang + ccache (fanquake) Pull request description: This was added in 386efb7695debaf5f0f328a2e4c9abc342161665 to address spammy Clang warnings when building with ccache. The issue was addressed in [ccache 3.2](https://bugzilla.samba.org/show_bug.cgi?id=8118), and from a look at most major distros, it's only Debian Jessie that has a version of ccache older than that ([3.1](https://packages.debian.org/jessie/ccache)). Therefore I think it's acceptable to drop this workaround, and re-enable warnings for unused driver arguments (when compiling using Clang and ccache).

None of the changes are bug fixes (they only change behavior for corrupted asmap files), but they may make things easier to follow. In a second step, a sanity checker is added that effectively executes every potential code path through the asmap file, checking the same failure cases as the interpreter, and more. It takes around 30 ms to run for me for a 1.2 MB asmap file. I've verified that this accepts asmap files constructed by https://github.com/sipa/asmap/blob/master/buildmap.py with a large dataset, and no longer accepts it with 1 bit changed in it.

CVE fix 1ad8ea2b73134bdd8d6b50704a019d47ad2191d8 net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix (Sebastian Falbesoner) Pull request description: The BIP37 bloom filter class `CBloomFilter` contains two flags `isEmpty`/`isFull` together with an update method with the purpose to, according to the comments, "avoid wasting cpu", i.e. the mechanism should serve as an optimization for the trivial cases of empty (all bits zero) or full (all bits one) filters. However, the real reason of adding those flags (introduced with commit https://github.com/bitcoin/bitcoin/commit/37c6389c5a0ca63ae3573440ecdfe95d28ad8f07 by gmaxwell) was a _covert fix_ of [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700), a vulnerability that allowed a divide-by-zero remote node crash. According to gmaxwell himself (https://github.com/bitcoin/bitcoin/pull/9060#issuecomment-257749165): > the IsEmpty/IsFull optimizations were largely a pretextual optimization intended to make unexploitable a remote crash vulnerability (integer division by zero) that existed in the original bloom filtering code without disclosing it. I'm doubtful that they are all that useful. :) For more information on how to trigger this crash, see PR https://github.com/bitcoin/bitcoin/pull/18515 which contains a detailled description and a regression test. It has also been discussed on a [recent PR club meeting on fuzzing](https://bitcoincore.reviews/18521.html). The covert fix code already led to issues and PR based on the wrong assumption that the flags are there for optimization reasons (see #16886 and #16922). This PR gets rid of the flags and the update method and just focuses on the CVE fix itself, i.e. it can be seen as a revert of the covert fix commit modulo the actual fix.
