Notable changes compared to v24: - dropped thaw/freeze mechanism, as duplicate keep-alives gave me issues with migration of half-closed connections and in general they proved to be too rigid to quickly fix things as I needed to do. Kept all the fixes, though - fixed error handling on target, e.g. clearing flags, calling flow_cancel() as needed, etc. - added tests for half-closed sockets, fixed headers and descriptions - fix build with musl (1.25), and warnings on i686, armv6l, cppcheck and clang-tidy reports - drop "queue plugging" mechanism: it turns out that the kernel actually generates ACKs from the padding we send to our own receive queue, even in repair mode (!) All tests are happy. This looks quite solid and mergeable to me as it is.
