Subject: [PATCH v25 0/2] State migration, somewhat polished
Date: Sat, 15 Feb 2025 06:23:09 +0100 [thread overview]
Message-ID: <20250215052311.2945229-1-sbrivio@redhat.com> (raw)
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.
