Resetting the timer after shutdown was initiated would keep
a reference to the object inside ASIO, which would keep the
connection alive until the timer timed out
The problem actually exists in two parts:
1. When sending chunks over a connection, if the queue size is
greater than N, the seed is predictable across every monero node.
>"If rand() is used before any calls to srand(), rand() behaves as if
it was seeded with srand(1). Each time rand() is seeded with the same seed, it
must produce the same sequence of values."
2. The CID speaks for itself: "'rand' should not be used for security-related
applications, because linear congruential algorithms are too easy to break."
*But* this is an area of contention.
One could argue that a CSPRNG is warranted in order to fully mitigate any
potential timing attacks based on crafting chunk responses. Others could argue
that the existing LCG, or even an MTG, would suffice (if properly seeded). As a
compromise, I've used an MTG with a full bit space. This should give a healthy
balance of security and speed without relying on the existing crypto library
(which I'm told might break on some systems since epee is not (shouldn't be)
dependent upon the existing crypto library).
bdcdb0e Remove unused code under WINDWOS_PLATFORM guard (tomsmeding)
a84aa04 syncobj.h no longer defines shared_guard, so remove those define's (tomsmeding)
The removed preprocessor macro's refer to types that are not defined in
the file anymore; the only other place where shared_guard is defined is
in winobj.h, which also defines the same macro's. Therefore, this change
is safe.
(Side note is that these macro's weren't used at all anyway, but that is
orthogonal to the issue.)

ipv6 addresses are to be specified as "[xx:xx:xx::xx:xx]:port" except
in the cases of the cli args for bind address. For those the square
braces can be omitted.
The tar archives generated by gitian are currently unversioned. This
adds either a tag name when building from a tag, or a short commit id
when building from a commit hash.
The macos binaries in release v0.14.1.0 were compiled with the buggy
hidapi-0.8.0-rc1 version. This resulted in users not being able to use
their Ledger with the latest cli wallet. After the patch depends now
fetches the source from the libusb hidapi repository that has taken over
maintenance of hidapi.
Before this commit the icu4c repo was fetched from TheCharlatan's
repository. This step was made, because up until recently the source
code was hosted on sourceforge and their downloads proved very
unreliable. The origin is now the official icu4c repository.
Also remove some commented lines left over from development.
This commits adds the `--no-apt` flag to the gitian-build.py script.
This allows gitian builds to be run without root access and non-debian
based operating systems.
To speedup the depends cached builds, remove some some clutter from the package
files. This mainly incldues removing all the shared libraries and .la
linker files. It also gives stronger guarantees that monero only links
the static libs without any external rvalues.
- This addresses https://www.openssl.org/news/secadv/20190226.txt (CVE: 2019-1559) which impacted all versions of openssl-1.0.
Note that this does not address CVE-2019-1543 (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-1543), which impacts all versions of openssl 1.1 through 1.1.0j and 1.1.1b.
The above (1.1) is patched in openssl, where it was marked as low severity. Similar issues possibly present in monero, should be looked into w.r.t. CVE-2019-1543.

add two RSA based ciphers for Windows/depends compatibility
also enforce server cipher ordering
also set ECDH to auto because vtnerd says it is good :)
When built with the depends system, openssl does not include any
cipher on the current whitelist, so add this one, which fixes the
problem, and does seem sensible.
It can allocate a lot when getting a lot of connections
(in particular, the stress test on windows apparently pushes
that memory to actual use, rather than just allocated)
When closing connections due to exiting, the IO service is
already gone, so the data exchange needed for a gracious SSL
shutdown cannot happen. We just close the socket in that case.
An override for the wallet to daemon connection is provided, but not for
other SSL contexts. The intent is to prevent users from supplying a
system CA as the "user" whitelisted certificate, which is less secure
since the key is controlled by a third party.
This allows "chain" certificates to be used with the fingerprint
whitelist option. A user can get a system-ca signature as backup while
clients explicitly whitelist the server certificate. The user specified
CA can also be combined with fingerprint whitelisting.
The former has the same behavior with single self signed certificates
while allowing the server to have separate short-term authentication
keys with long-term authorization keys.
If the verification mode is `system_ca`, clients will now do hostname
verification. Thus, only certificates from expected hostnames are
allowed when SSL is enabled. This can be overridden by forcible setting
the SSL mode to autodetect.
Clients will also send the hostname even when `system_ca` is not being
performed. This leaks possible metadata, but allows servers providing
multiple hostnames to respond with the correct certificate. One example
is cloudflare, which getmonero.org is currently using.
If SSL is "enabled" via command line without specifying a fingerprint or
certificate, the system CA list is checked for server verification and
_now_ fails the handshake if that check fails. This change was made to
remain consistent with standard SSL/TLS client behavior. This can still
be overridden by using the allow any certificate flag.
If the SSL behavior is autodetect, the system CA list is still checked
but a warning is logged if this fails. The stream is not rejected
because a re-connect will be attempted - its better to have an
unverified encrypted stream than an unverified + unencrypted stream.
Using `verify_peer` on server side requests a certificate from the
client. If no certificate is provided, the server silently accepts the
connection and rejects if the client sends an unexpected certificate.
Adding `verify_fail_if_no_cert` has no affect on client and for server
requires that the peer sends a certificate or fails the handshake. This
is the desired behavior when the user specifies a fingerprint or CA file.
Currently a client must provide a certificate, even if the server is
configured to allow all certificates. This drops that requirement from
the client - unless the server is configured to use a CA file or
fingerprint(s) for verification - which is the standard behavior for SSL
servers.
The "system-wide" CA is not being used as a "fallback" to verify clients
before or after this patch.
Specifying SSL certificates for peer verification does an exact match,
making it a not-so-obvious alias for the fingerprints option. This
changes the checks to OpenSSL which loads concatenated certificate(s)
from a single file and does a certificate-authority (chain of trust)
check instead. There is no drop in security - a compromised exact match
fingerprint has the same worse case failure. There is increased security
in allowing separate long-term CA key and short-term SSL server keys.
This also removes loading of the system-default CA files if a custom
CA file or certificate fingerprint is specified.
Manually initialize the array_entry_t iterator to ensure it points
to the correct m_array, thereby preventing a potential use-after-free
situation.

This avoids the annoying case where the shell prints its prompt
after the last line from Monero output, causing line editing to
sometimes go wonky, for lack of a better term
RPC connections now have optional tranparent SSL.
An optional private key and certificate file can be passed,
using the --{rpc,daemon}-ssl-private-key and
--{rpc,daemon}-ssl-certificate options. Those have as
argument a path to a PEM format private private key and
certificate, respectively.
If not given, a temporary self signed certificate will be used.
SSL can be enabled or disabled using --{rpc}-ssl, which
accepts autodetect (default), disabled or enabled.
Access can be restricted to particular certificates using the
--rpc-ssl-allowed-certificates, which takes a list of
paths to PEM encoded certificates. This can allow a wallet to
connect to only the daemon they think they're connected to,
by forcing SSL and listing the paths to the known good
certificates.
To generate long term certificates:
openssl genrsa -out /tmp/KEY 4096
openssl req -new -key /tmp/KEY -out /tmp/REQ
openssl x509 -req -days 999999 -sha256 -in /tmp/REQ -signkey /tmp/KEY -out /tmp/CERT
/tmp/KEY is the private key, and /tmp/CERT is the certificate,
both in PEM format. /tmp/REQ can be removed. Adjust the last
command to set expiration date, etc, as needed. It doesn't
make a whole lot of sense for monero anyway, since most servers
will run with one time temporary self signed certificates anyway.
SSL support is transparent, so all communication is done on the
existing ports, with SSL autodetection. This means you can start
using an SSL daemon now, but you should not enforce SSL yet or
nothing will talk to you.
Further speedups to icu compilation, it is faster to run the
pre-generated configure scripts.
Ensure that the native protobuf installation only generates the required
libraries and binaries.
Disable qt compilation when running travis on windows. Qt is used for
lrelease, the travis recipe instead usese the a local installation of
lrelease.
Remove various packages and options from the travis recipe.
Update Readline to version 8.0. The previously used url 404'd sometimes,
use the official gnu ftp server instead.
Remove unused cmake config.
Building with docker is arguably easier and more familiar to most people
than either kvm, or lxc.
This commit also relaxes the back compat requirement a bit. 32 bit linux
now uses glibc version 2.0. Also, the docker shell could not handle gcc arguments
containing spaces, so the explicit '-DFELT_TYPE' declaration was dropped.
Lastly, this removes some packages from the osx descriptor.

- Support for ".onion" in --add-exclusive-node and --add-peer
- Add --anonymizing-proxy for outbound Tor connections
- Add --anonymous-inbounds for inbound Tor connections
- Support for sharing ".onion" addresses over Tor connections
- Support for broadcasting transactions received over RPC exclusively
over Tor (else broadcast over public IP when Tor not enabled).
The blockchain prunes seven eighths of prunable tx data.
This saves about two thirds of the blockchain size, while
keeping the node useful as a sync source for an eighth
of the blockchain.
No other data is currently pruned.
There are three ways to prune a blockchain:
- run monerod with --prune-blockchain
- run "prune_blockchain" in the monerod console
- run the monero-blockchain-prune utility
The first two will prune in place. Due to how LMDB works, this
will not reduce the blockchain size on disk. Instead, it will
mark parts of the file as free, so that future data will use
that free space, causing the file to not grow until free space
grows scarce.
The third way will create a second database, a pruned copy of
the original one. Since this is a new file, this one will be
smaller than the original one.
Once the database is pruned, it will stay pruned as it syncs.
That is, there is no need to use --prune-blockchain again, etc.
This includes more fine grained configure options and skipping the
openssl and zlib dependencies when compiling qt. The zlib and libevent
packages are removed.
Number matching semantics are slightly changed: since this is used
as a filter to check whether a number is signed and/or floating
point, we can speed this up further. strto* functions are called
afterwards and will error out where necessary. We now also accept
numbers like .4 which were not accepted before.
The strto* calls on a boost::string_ref will not access unallocated
memory since the parsers always stop at the first bad character,
and the original string is zero terminated.

It comes before the logger is initialized, so gets displayed
even though it should not be by default, and apparenly comes
too early for (some versions of) Android, where it crashes.
Turns out getting the global shared_ptr hits the profile,
and passing it around still keeps it at close to ~1% CPU,
which is too much for mostly silent logging.
Leak the object instead, which is even safer for late logging.
- webusb transport based on libusb added. Provides direct access to Trezor via USB, no need for Trezor bridge.
- trezor protocol message handler improved, no recursion used. Ready for upcoming integration tests.
- libusb (for docker) bumped from v1.0.9 to v1.0.22, newer version required for webusb transport, for device enumeration.
- cmake improvements and fixes. Cmake Trezor checks are moved to a dedicated CheckTrezor.cmake file. In case of a problem Trezor is excluded from build.
- ifdefs made consistent to Ledger.
- UDP Transport enumeration disabled by default in release mode
This prevents exceptions from showing up in various awkward
places such as dtors, since the only exception that can be
thrown is a lock failure, and nothing handles a lock failure
anyway.
The version prefix 'v' should just be set constantly.

This should allow building commits as well, if a commit
is passed in instead of a tag.

Windows is built with a seperate descriptor to handle additional changes
that need to be done to the end binary. Consolidate the gitian-build
script for this change.
The signature prepare tool and the gitian-builder git repo should be
checked for their content. For this purpose, checkout the gitian-builder
repo at a specific commit and take the sha256sum of the osslsigncode
tool.
This adds a build script to run gitian builds for linux.
The build script was copied from bitcoin and then adapted for monero.
Build step documentation is outlined in the README in the contrib/gitian
directory.

The configure script in hidapi and libsodium tried to find clang in /usr/bin,
even though the correct prefix was passed in. This sets the correct CC flag.
This was previously undetected, because clang and the sdk where
installed in the global environment.
This also fixes a subsequent error, where IOKIT and CoreFoundation are
not found, again for the reason stated above.
Clang needs to get its cctools path passed directly for the hid build to
succeed.
