2021-05-14Merge bitcoin/bitcoin#21889: macho: check for control flow instrumentationW. J. van der Laan
42b589d18fed5e2b3cb6ac9937e3333619967a6c scripts: test for MACHO control flow instrumentation (fanquake) 469a5bc4fa74d70556cce454efbc38fb7945acd8 build: build Boost with -fcf-protection when targeting Darwin (fanquake) Pull request description: Addresses the macOS portion of #21888. Build Boost with `-fcf-protection` when targeting Darwin. This should be ok, because our cross-compiler (Clang 10) supports the option, and I'd expect all versions of Apple Clang being used to compile Core would also support it. Building Boost with this option is required so that the `main` provided to `test_bitcoin` has instrumentation. Note that the presence of instrumentation does not mean it will be used, as that is determined at runtime by the CPU. From the Intel control flow enforcement documentation: > The ENDBR32 and ENDBR64 instructions will have the same effect as the NOP instruction on Intel 64 processors that do not support CET. On processors supporting CET, these instructions do not change register or flag state. This allows CET instrumented programs to execute on processors that do not support CET. Even when CET is supported and enabled, these NOP–like instructions do not affect the execution state of the program, do not cause any additional register pressure, and are minimally intrusive from power and performance perspectives.

(Klement Tan) Pull request description: Changed `use -jX here for parallelism` to `use "-j N" for N parallel jobs` **Rationale**: In my opinion `use -jX here for parallelism` is quite ambiguous as it could be perceived as a single option without any argument. Ie running: ```sh make -jX ``` Embarrassingly this caused me to be stuck for quite a long time until I opened the help menu for `make` but if I am the only one who faced this issue I would be happy to close this PR.

105941b726c078642e785ecb7b6834ba814381b0 net: use stronger AddLocal() for our I2P address (Vasil Dimov) Pull request description: There are two issues: ### 1. Our I2P address not added to local addresses. * `externalip=` is used with an IPv4 address (this sets automatically `discover=0`) * No `discover=1` is used * `i2psam=` is used * No `externalip=` is used for our I2P address * `listenonion=1 torcontrol=` are used In this case `AddLocal(LOCAL_MANUAL)` [is used](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/torcontrol.cpp#L354) for our `.onion` address and `AddLocal(LOCAL_BIND)` [for our](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/net.cpp#L2247) `.b32.i2p` address, the latter being [ignored](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/net.cpp#L232-L233) due to `discover=0`. ### 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart. * `externalip=` is used with our I2P address (this sets automatically `discover=0`) * No `discover=1` is used * `i2psam=` is used In this case, initially `externalip=` causes our I2P address to be [added](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/init.cpp#L1266) with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down [we do](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/net.cpp#L2234) `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, [we do](https://github.com/bitcoin/bitcoin/blob/94f83534e4b771944af7d9ed0f40746f392eb75e/src/net.cpp#L2247) `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`. To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

Both v0.21 and master are affected. Since #19191, noban is a multi-flag that implies download, so the conditional in `CConnman::Bind()` using a bitwise AND on noban will return the same result for both the noban status and the download status. This means that download peers are incorrectly not being added to local addresses because they are mistakenly seen as noban peers. The second commit adds unit test coverage to illustrate and test the noban/download relationship and the `NetPermissions` operations involving them. The final commit adds documentation and disallows calling `NetPermissions::ClearFlag()` with any second param other than `NetPermissionFlags` "implicit" -- per current usage in the codebase -- because `ClearFlag()` should not be called with any second param that is a subflag of a multiflag, e.g. "relay" or "download," as that would leave the result in an invalid state corresponding to none of the existing NetPermissionFlags.

2021-05-11net: use stronger AddLocal() for our I2P addressVasil Dimov
There are two issues: 1. Our I2P address not added to local addresses. * `externalip=` is used with an IPv4 address (this sets automatically `discover=0`) * No `discover=1` is used * `i2psam=` is used * No `externalip=` is used for our I2P address * `listenonion=1 torcontrol=` are used In this case `AddLocal(LOCAL_MANUAL)` is used for our `.onion` address and `AddLocal(LOCAL_BIND)` for our `.b32.i2p` address, the latter being ignored due to `discover=0`. 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart. * `externalip=` is used with our I2P address (this sets automatically `discover=0`) * No `discover=1` is used * `i2psam=` is used In this case, initially `externalip=` causes our I2P address to be added with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down we do `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, we do `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`. To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

7962e0dde8bbd0fa3dd702e2224774f1edaadcb6 qt: Do not clear console prompt when font resizing (Hennadii Stepanov) d2cc3390054616c73f72a59f864700f6de14067b qt, refactor: Drop redundant history cleaning in RPC console (Hennadii Stepanov) 4f0ae472e22990ad9e734faea4adacef8df449bb qt: Untie irrelevant signal-slot parameters (Hennadii Stepanov) Pull request description: On master, a console resize event will clear the prompt. To fix this, we store the content of the prompt and re-set it upon a resize. This preserves the prompt text throughout resizes. The text will still clear when you click the clear button, as it should. **Master** | Before Resize | After Resize | | ----------------- | ------------ | | ![master-beforeresize](https://user-images.githubusercontent.com/23396902/113553721-2a428d80-95c6-11eb-971b-bb77151bc6d5.png) | ![master-afterresize](https://user-images.githubusercontent.com/23396902/113553769-3d555d80-95c6-11eb-9cdb-9ad1fd7208a9.png) | **PR** | Before Resize | After Resize | | ----------------- | ------------ | | ![pr-beforeresize](https://user-images.githubusercontent.com/23396902/113553885-6f66bf80-95c6-11eb-8317-0975f1ebd444.png) | ![pr-afterresize](https://user-images.githubusercontent.com/23396902/113553906-75f53700-95c6-11eb-9a32-b64d8aba98e5.png) | Closes #269 ACKs for top commit: laanwj: Code review ACK 7962e0dde8bbd0fa3dd702e2224774f1edaadcb6 hebasto: ACK 7962e0dde8bbd0fa3dd702e2224774f1edaadcb6 Talkless: tACK 7962e0dde8bbd0fa3dd702e2224774f1edaadcb6, tested on Debian Sid with Qt 5.15.2 Tree-SHA512: a6f19d3f80e2e47725cff5d6e15862b6cb793a65dfcaded15f23bba051088cd3317f068f93290c9b09d0a90f5fcac1c5a4610cc417cc5961ba6d005fe5049ab0

This avoids accidentally mixing it up with other hashes (like block hashes).

2021-05-11refactor: remove redundant fOnlySafe argumentt-bast
The fOnlySafe argument to AvailableCoins is now redundant, since #21359 added a similar field inside the CCoinControl struct. Not all code paths set a CCoinControl instance, but when it's missing we can default to using only safe inputs which is backwards-compatible.
