From: Julien Grall <jgr...@amazon.com>Hi all, At the moment, Live-Update will, by default, not proceed if there are in-flight transactions. It is possible force it by passing -F but this will break any connection with in-flight transactions. There are PV drivers out that may never terminate some transaction. On host running such guest, we would need to use -F. Unfortunately, this also risks to break well-behaving guests (and even dom0) because Live-Update will happen as soon as the timeout is hit. This series aims to allow to Live-Update more safely even when the option -F is used. The first part of the series contains a few fixes for bug found while testing Live-Update. Cheers, Julien Grall (10): MAINTAINERS: Add myself as reviewers for tools/xenstore tools/xenstored: Introduce lu_get_connection() and use it tools/xenstore: Don't assume conn->in points to the LU request tools/xenstored: Limit the number of requests a connection can delay tools/xenstored: xenstored_core.h should include fcntl.h tools/xenstored: Introduce a wrapper for conn->funcs->can_{read, write} tools/xenstored: delay_request: don't assume conn->in == in tools/xenstored: Extend restore code to handle multiple input buffer
I have committed the first 8 patches.
tools/xenstored: Dump delayed requests tools/xenstored: Delay new transaction while Live-Update is pending
Cheers, -- Julien Grall
