d419fdedbe34c7ea19c0473660cc1b486b4e70d8 [net processing] Don't add AlreadyHave txs to recentRejects (Troy Giorshev)
Pull request description:
If we already have a transaction, don't add it to recentRejects
Now, we only add a transaction to our recentRejects filter if we didn't already have it, meaning that it is added at most once, as intended.

Outbound peer logic prevents connecting to addresses that we're already
connected to, so prevent inadvertent eviction of current peers via
test-before-evict by checking this condition and marking current peer's
addresses as Good().
Co-authored-by: John Newbery <john@johnnewbery.com>
Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
- add new signet chain
- update change "uptime" column name to "age" per suggestion by 0xB10C (Timo)
- add an additional digit to mping field width
- change m_networks_size from size_t to uint8_t, as size_t was a holdover
from m_networks_size being defined as size_t m_networks.size() in a draft
- order Peer struct members by decreasing memory size

56a461f72796ca60de28e78f144741eb1a4f5213 wallet: fix buffer over-read in SQLite file magic check (Sebastian Falbesoner)
Pull request description:
Looking at our new SQLite database code, I noticed that there is a potential problem in the method `IsSQLiteFile()`: If there is no terminating zero within the first 16 bytes of the file, the `magic` buffer would be over-read in the `std::string` constructor for `magic_str`. Fixed by using the "from buffer" variant of the string ctor (that also takes a size) rather than the "from c-string" variant (see http://www.cplusplus.com/reference/string/string/string/).
The behaviour can be reproduced by the following steps:
* Creating a file of at least 512 bytes in size (to pass the minimum size check) that doesn't contain zero bytes in the magic area, e.g. simply:
`$ python3 -c "print('A'*512)" > /tmp/corrupt_wallet`
* Showing content and size of the `magic_str` string in case the magic check fails
* Create a simple unit test that simply calls `IsSQLiteFile` with the corrupt wallet file
* Run the unit test and see the random gibberish output of `magic_str` after 16 `A`s :-)
Or, TLDR variant, just get the branch https://github.com/theStack/bitcoin/tree/reproduce_sqlite_magic_overread, compile unit Tests and run the script `./reproduce_sqlite_magic_overread.sh`.
Note that this is the minimal diff, probably it would be better to avoid `std::string` at all in this case and just use `memcmp`, strings that include null bytes are pretty confusing.

If `-logips -debug=net` is specified then we print the contents of the
version message we send to the peer, including his address. Because the
addresses in the version message use pre-BIP155 encoding they cannot
represent a Tor v3 address and we would actually send 16 `0`s instead (a
dummy IPv6 address). However we would print the full address in the log
message. Before this fix:
```
2020-10-21T12:24:17Z send version message: version 70016, blocks=653500, us=[::]:0, them=xwjtp3mj427zdp4tljiiivg2l5ijfvmt5lcsfaygtpp6cw254kykvpyd.onion:8333, peer=0
```
This is confusing because we pretend to send one thing while we actually
send another. Adjust the printout to reflect what we are sending. After
this fix:
```
2020-10-21T12:26:54Z send version message: version 70016, blocks=653500, us=[::]:0, them=[::]:0, peer=0

c8abbc9d1fd8f77b5dcf31cf7a6dd6aac5d1c75c p2p: declare Announcement::m_state as uint8_t, add getter/setter (Jon Atack)
Pull request description:
Change `Announcement::m_state` in `tx_request.cpp` from type `State` to `uint8_t` and add a getter and setter for the conversion to/from `State`. This should silence these travis ci gcc compiler warnings:
```
txrequest.cpp:73:21: warning: ‘{anonymous}::Announcement::m_state’ is
too small to hold all values of ‘enum class {anonymous}::State’
State m_state : 3;
^
```
The gcc warnings are based on the maximum value held by the underlying uint8_t enumerator type, even though the intention of the bitfield declaration is the maximum declared enumerator value. They have apparently been silenced in gcc 8.4+ and 9.3+ according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61414.
