Pull request description:
No one seems to use this "feature", and at any rate the behavior of relaying transactions when they violate local policy is error-prone, if we ever consider changing the ban behavior of our software from one version to the next.
Defaulting this to off means that users who use -whitelist won't be unexpectedly surprised by this interaction. If anyone is still relying on this feature, it can still be explicitly turned on.

da6011826a Fix macOS launch-at-startup memory issue (Jonas Schnelli)
516437a1b7 Qt: remove macOS launch-at-startup option when compiled with > macOS 10.11 (Jonas Schnelli)
Pull request description:
The launch-at-startup API Bitcoin Core uses on macOS where removed in macOS 10.11 leading to a segmentation-fault due to the weak-linking when not actively compiled against SDK 10.11 (`-mmacosx-version-min=10.11`)
This PR removes the launch-at-startup feature on macOS when compiled with macOS min version > 10.11 (the default is always the macOS version you compile on).
**The depends built binaries (Gitian) are not affected since we are building with min macOS 10.10.**
Users self compiling on macOS > 10.11 can re-enable the feature by compiling with min version <= 10.11 (`CXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" ./configure`)
**Isn't there a new API from Apple?**
Yes, [there is](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLoginItems.html).
It will require to create a helper application which needs to be embedded in the .app folder (needs code signing as well). Developers willing to go down that rabbit hole are welcome.

This allows incoming connections from peers which are only banned
due to an automatic misbehavior ban if doing so won't fill inbound.
These peers are preferred for eviction when inbound fills, but may
still be kept if they fall into the protected classes. This
eviction preference lasts the entire life of the connection even
if the ban expires.
If they misbehave again they'll still get disconnected.
The main purpose of banning on misbehavior is to prevent our
connections from being wasted on unhelpful peers such as ones
running incompatible consensus rules. For inbound peers this
can be better accomplished with eviction preferences.
A secondary purpose was to reduce resource waste from repeated
abuse but virtually any attacker can get a nearly unlimited
supply of addresses, so disconnection is about the best we can
do.
b301950df3 Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev)
faf29dd019 Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev)
Pull request description:
This PR is re-submission of #14156, which was automatically closed by github (glitch?)
Original description:
This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`.
Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused.
The rationale for this change is:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

Pull request description:
This does not remove OpenSSL, but makes our own PRNG the 'main' one; for GetStrongRandBytes, the OpenSSL RNG is still used (indirectly, by feeding its output into our PRNG state).
It includes a few policy changes (regarding what entropy is seeded when).
Before this PR:
* GetRand*:
* OpenSSL
* GetStrongRand*:
* CPU cycle counter
* Perfmon data (on Windows, once 10 min)
* /dev/urandom (or equivalent)
* rdrand (if available)
* From scheduler when idle:
* CPU cycle counter before and after 1ms sleep
* At startup:
* CPU cycle counter before and after 1ms sleep
After this PR:
* GetRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* GetStrongRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* From scheduler when idle:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter before and after 1ms sleep
* Perfmon data (on Windows, once every 10 min)
* At startup:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* Perfmon data (on Windows, once every 10 min)
The interface of random.h is also simplified, and documentation is added.
This implements most of #14623.

It includes the following policy changes:
* All GetRand* functions seed the stack pointer and rdrand result
(in addition to the performance counter)
* The periodic entropy added by the idle scheduler now seeds stack pointer,
rdrand and perfmon data (once every 10 minutes) in addition to
just a sleep timing.
* The entropy added when calling GetStrongRandBytes no longer includes
the once-per-10-minutes perfmon data on windows (it is moved to the
idle scheduler instead, where latency matters less).
Other changes:
* OpenSSL is no longer seeded directly anywhere. Instead, any generated
randomness through our own RNG is fed back to OpenSSL (after an
additional hashing step to prevent leaking our RNG state).
* Seeding that was previously done directly in RandAddSeedSleep is now
moved to SeedSleep(), which is indirectly invoked through ProcRand
from RandAddSeedSleep.
* Seeding that was previously done directly in GetStrongRandBytes()
is now moved to SeedSlow(), which is indirectly invoked through
ProcRand from GetStrongRandBytes().
This guarantees that OpenSSL is initialized properly whenever randomness
is used, even when that randomness is invoked from global constructors.
Note that this patch uses Mutex directly, rather than CCriticalSection.
This is because the lock-detection code is not necessarily initialized
during global constructors.

* Writing to the chain state or adding transactions to the transaction pool -> Take both `cs_main` and `mempool::cs`
* Reading either or removing transactions from the the transaction pool -> Take only the appropriate lock

fb3ce75807 Don't label transactions "Open" while catching up (Hennadii Stepanov)
Pull request description:
Fix#13299.
Since the default `nSequence` is `0xFFFFFFFE` and locktime is enabled, the checking `wtx.is_final` is meaningless until the syncing has completed (ref: #1026).
This PR makes the wallet mark a transaction "Unconfirmed" instead of misleading "Open for NNN more blocks" when syncing after a period of being offline.

645e905c32 doc: Add release notes for unloadwallet change to synchronous call (João Barbosa)
c37851de57 rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)
Pull request description:
Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.
Replaces #14919, fixes#14917.

There was only one place in the codebase where we're directly reading >32 bytes from
the RNG. One possibility would be to make the built-in RNG support large reads, but
using FastRandomContext lets us reuse code better.
There is no change in behavior here, because the FastRandomContext constructor
uses GetRandBytes internally.
9d0e52834 implements different disk sizes for different networks on intro (marcoagner)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

- Make ToLower and ToUpper take a char — Unfortunately, `std::string` elements are (bare) chars. As these are the most likely type to be passed to these functions, make them use char instead of unsigned char. This avoids some casts.

fa48baf23e wallet: Avoid leaking locktime fingerprint when anti-fee-sniping (MarcoFalke)
453803adc9 [test] wallet_txn_clone: Correctly clone txin sequence (MarcoFalke)
Pull request description:
The wallet sets the locktime to the current height of our active chain. This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.
For reference, I visualized "locktime-reuse" with the data:
* blocks 545k-555k (both inclusive)
* locktimes<=60k
* excluding coinbase txs

ca126d490b Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)
Pull request description:
`mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.
`PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.
Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.
After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);
The resulting address `0x00000003ffdf` is then written to.

6b25f29a91 Use std::vector API for construction of test data. (Daniel Kraft)
Pull request description:
For constructing test scripts, use `std::vector` and, in particular, `std::vector::insert` to insert 20 zero bytes rather than listing the full array of bytes explicitly. This makes the code easier to read and makes it immediately obvious what the structure of the data is, without having to count the zeros to understand it.
Of course, that is a matter of taste - so if you disagree that the change makes the code easier to read, let me know.
This has been split out of #14752.
