In this commit, we add an additional test case for inherited RBF replacement. This test case asserts that if a parent is marked as being replaceable, but the child isn't, then the child can still be replaced as according to BIP 125 it shoudl _inhreit_ the replaceability of its parent. The addition of this test case was prompted by the recently discovered Bitcoin Core "CVE" [1]. It turns out that bitcoind doesn't properly implement BIP 125. Namely it fails to allow a child to "inherit" replaceability if its parent is also replaceable. Our implementation makes this trait rather explicit due to its recursive implementation. Kudos to the original implementer @wpaulino for getting this correct. [1]: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-May/018893.html.

Doesn't need any addition to the release notes (#1706) I suppose. |
