Perform the following ELF security checks:
- PIE: Check for position independent executable (PIE), allowing for address space randomization
- NX: Check that no sections are writable and executable (including the stack)
- RELRO: Check for read-only relocations, binding at startup
- Canary: Check for use of stack canary
Also add a check to symbol-check.py that checks that only the subset of
allowed libraries is imported (to avoid incompatibilities).

Common sentiment is that the miniupnpc codebase likely contains further
vulnerabilities.
I'd prefer to get rid of the dependency completely, but a compromise for
now is to at least disable it by default.

The two timeouts for the server and client, are essentially different:
- In the case of the server it should be a lower value to avoid clients
clogging up connection slots
- In the case of the client it should be a high value to accomedate slow
responses from the server, for example for slow queries or when the
lock is contended
Split the options into `-rpcservertimeout` and `-rpcclienttimeout` with
respective defaults of 30 and 900.

This allows users to specify, e.g. raise, the default timeout of 60
seconds. Some bitcoind instances, especially long running ones on slow
hardware, require a higher timeout for a clean shut down.
Also add a comment to bitcoind.openrc's 'retry=', since it is not
obvious from the variable name what it does.
Allow for non-8333 nodes to appear in the internal seeds. This will
allow bitcoind to bypas a filter on 8333. This also makes it possible to
use the same tool for e.g. testnet.
As hosts with multiple nodes per IP are likely abusive, add a filter to
remove these (the ASN check will take care of them for IPv4, but not
IPv6 or onion).
- Moved all seed related scripts to contrib/seeds for consistency
- Updated `makeseeds.py` to handle IPv6 and onions, fix regular
expression for recent Bitcoin Core versions
- Fixed a bug in `generate-seeds.py` with regard to IPv6 parsing
Rather than fetching a signature.tar.gz from somewhere on the net, instruct
Gitian to use a signature from a tag in the bitcoin-detached-sigs repository
which corresponds to the tag of the release being built.
This changes detached-sig-apply.sh to take a dirname rather than a tarball as
an argument, though detached-sig-create.sh still outputs a tarball for
convenience.

For Gitian releases:
- Windows builds remain unchanged. libstdc++ was already linked statically.
- OSX builds remain unchanged. libstdc++ is tied to the SDK and not worth
messing with.
- Linux builds now statically link libstdc++.
For Travis:
- Match the previous behavior by adding --enable-reduce-exports as
necessary.
- Use static libstdc++ for the full Linux build.
This reverts commit 1078fb0885 (and thus
pull #5623). It has various issues:
- Pull request names get cut off at ", see e.g. a026a56
- Merge script no longer copes with pulls that have a milestone
attached, due to a duplicate 'title' in JSON that is not handled by the
ad-hoc parsing.
Since permissions and timestamps are changed for the sake of determinism,
. must not be added to the archive. Otherwise, tar may try to modify pwd when
extracting.
- Check that image contents match pre- and post- crushing.
- Also remove use of external tool to compute sha256 in favor of hashlib.
- contrib: remove all use of shell=True in strip_pngs.py
Using `shell=True` can be a security hazard. See e.g.
https://docs.python.org/2/library/subprocess.html#subprocess.check_output
- Add a space after the fixed string prepended to file names when input or
output file changes
- Clarify the error message when the genesis block is not found in the
hash list (...why do we have this at all?)
Descriptors now make use of the dependencies builder, so results are cached.
A very new version (>= e9741525c) of Gitian should be used in order to take
advantage of caching.
* Support new rpc commands.
* Several commands now take an optional boolean includeWatchonly argument.
* "help" now has section headers, ignore them when compiling list of commands.
Make it possible to read blocks in any order. This will be required
after headers-first (#4468), so should be merged before that.
- Read block header. For expected blocks, continue, else skip.
- For in-order blocks: copy block contents directly. Write prior
out-of-order blocks if this connects a consecutive span.
- For out-of-order blocks, store extents of block data for later
retrieval. Cache out-of-order blocks in memory up to 100MB
(configurable).
Code signing failed for me on OSX 10.9.5 because the
Versions/Current symbolic links were being replaced
with a duplicate copy of the frameworks' code.
Releases were bigger than they needed to be, for the
same reason.
The approach from 65f3fa8d1 worked for signing on 10.9.4, but not newer
versions. 10.9.5 (and up) want each framework to stand alone.
Now in addition to copying the plist's from Qt for each framework, we put them
in per-version dirs and only symlink to the latest, rather than using symlinks
for any contents.

- Also remove unfinished/untranslated messages, they just take up space
in the ts and waste parsing time.
Fixes#4774.
This was typically ensured implicitly by virtue of normal bitcoind
operation. Adding an explicit check provides a stronger guarantee, and
it is cheap to add.
Break into two steps:
* Generate hash list
* Build data file(s) from local bitcoind blocks/ directory.
This supports building one large bootstrap.dat, or multiple
smaller blocks/blkNNNNN.dat files.
Starting with 10.9, Framework versions must be signed individually, rather
than as a single bundle version, in order to be properly codesigned. This
change ensures that the proper plist files and symlinks are present prior to
packaging.
Running git version 2.1.0 on OSX (homebrew), I get

I'm guessing git command-line parsing got more strict recently?
When QT is linked statically, macdeploy can't infer its paths. While plugins
and frameworks don't need to be packaged, translations still do (for now).
As the `getwork` API doesn't exist anymore, currently this script is useless.
It would be nice to have a `getblocktemplate`-based Python example of a
miner, but there is no point in keeping this one around except to
confuse people.

Just in case - there is no vulnerability that affects ecdsa signing or
verification.
The MITM attack vulnerability (CVE-2014-0224) may have some effect on
our usage of SSL/TLS.
As long as payment requests are signed (which is the common case), usage
of the payment protocol should also not be affected.
The TLS usage in RPC may be at risk for MITM attacks. If you have
`-rpcssl` enabled, be sure to update OpenSSL as soon as possible.
A qt installation date snuck into the host utils (lrelease etc)
This doesn't affect the end product, so no dependency version bump.
It also doesn't explain why gavin's and mine build is different
If the `libqt4-dev` package is installed it picks the moc executable
from the system instead of our custom-built one. This results in
compatibility errors.
This commit convinces configure to pick the right one.

Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:
- create a transifex configuration file
- fetch all translations
- post-process them into valid and committable format
This avoids conflicts between the libraries statically linked into bitcoin and any
libraries we may link dynamically (such as Qt and OpenSSL, see issue #4094).
It also avoids start-up overhead to not export any unnecessary symbols.
To do this, build a linker script that marks all symbols as local.
Should make it possible to run the resulting GUI executable on
Linux distributions that use Qt 4.6, such as Debian Wheezy and Tails.
Builds a mini-SDK for building against Qt 4.6. This includes the headers
as well as host utilities such as `lrelease`, `qrc` and `moc`.
This speeds up the gitian build a bit - libqt4-dev pulled in a lot of packages,
and is no longer needed as this provides a replacement of our own.
Note: This does not replace the Qt build with at static library. After this
commit we still build dynamically against the system Qt library. The only
difference is that compatibility with an older version is maintained. This
loses minor GUI functionality (such as setPlaceholderText) but still
allows integration into the window management of the host OS, unlike
when statically linking.
Add a script to check that the (Linux) executables produced by gitian
only contain allowed gcc, glibc and libstdc++ version symbols. This
makes sure they are still compatible with the minimum supported Linux
distribution versions.
0f63504 Changed bitrpc.py's raw_input to getpass for passwords to conceal characters during command line input. Getpass is in Python stdlib so no additional dependencies required. (Eric S. Bullington)
Bumps deps-linux, deps-win dependency versions as well.
qt-win does not need to be bumped, as although it depends on deps-win,
Qt doesn't use miniupnp. I verified this by rebuilding the dependency
and checking the the output is the same. Not having to rebuild Qt is a
good thing as it is huge.
For qt5.2 on osx, the qcocoa plugin is mandatory. However, it fails to load
when qt.conf specifies the "plugin" path instead of the expected "Plugin". This
is in line with the documentation:
https://qt-project.org/doc/qt-5.0/qtdoc/qt-conf.html
I'm not sure how the plugins were loading before, unless the case-sensitivity
for OSX is new.
IIRC this was the case with 0.8.6, so let's keep this to avoid the risk
of losing connectable nodes with 0.9 release.
Also our miniupnpc library was recently updated and I've heard
reports that it works better than before now.
While building protobuf in different environments we noticed that
the host tool protoc was slightly different between builds (a symbol table
sorting issue).
Add a deterministic seed as well as disable zlib support.
Exected output is now:

No effect on final executables so no version bump.
Boost iostreams was picking up libz-dev in VirtualBox, as the recommended
way to build is now to make a VM with all dependency packages installed.
This caused a divergence between KVM/LXC build and VirtualBox
build results.
Fix this in the simplest possible way: add the libz-dev package.

It appears that the output was different every time.
This doesn't affect the final bitcoind/bitcoin-qt, but is confusing
nevertheless.
Fix it by using FAKETIME and zipping files in deterministic order.
OpenSSL was embedding a timestamp causing its build to be
non-deterministic.
Change deps-linux to be deterministic by using FAKETIME
as needed and disabling it when it gets in the way.
- Add 'g++' package (virtualbox images don't have this by default)
- Workaround for determinism in Qt5 resources
- Pass --disable-maintainer-mode --disable-dependency-tracking to

directory
- Fix typo -with-pic -> --with-pic
It is not necessary to rebuild dependencies after this commit.
Fixes#3610 and #3612.

Instead of using the boost provided by Ubuntu 12.04, build our own
dependency like we do for Windows.
This allows using a much newer version (1.55 versus 1.46) as well as
building with `-fPIC` so that `-pie` can be used in the x86-64 build.
Build only the mt-s (multithreaded, static runtime link)
variant of the library.
This cuts the build time in half.
Also prevent unpacked boost from ending up in output directory,
checking and hashing all the source files as output files this
takes a lot of time and is pointless.
