* qemu-ga: use key-value store to avoid recycling fd handles after restartMichael Roth2013-03-123-6/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hosts hold on to handles provided by guest-file-open for periods that can span beyond the life of the qemu-ga process that issued them. Since these are issued starting from 0 on every restart, we run the risk of issuing duplicate handles after restarts/reboots. As a result, users with a stale copy of these handles may end up reading/writing corrupted data due to their existing handles effectively being re-assigned to an unexpected file or offset. We unfortunately do not issue handles as strings, but as integers, so a solution such as using UUIDs can't be implemented without introducing a new interface. As a workaround, we fix this by implementing a persistent key-value store that will be used to track the value of the last handle that was issued across restarts/reboots to avoid issuing duplicates. The store is automatically written to the same directory we currently set via --statedir to track fsfreeze state, and so should be applicable for stable releases where this flag is supported. A follow-up can use this same store for handling fsfreeze state, but that change is cosmetic and left out for now.

* qemu-ga: make guest-sync-delimited available during fsfreezeMichael Roth2013-03-121-0/+1
| | | | | | | | | | | | | | We currently maintain a whitelist of commands that are safe during fsfreeze. During fsfreeze, we disable all commands that aren't part of that whitelist. guest-sync-delimited meets the criteria for being whitelisted, and is also required for qemu-ga clients that rely on guest-sync-delimited for re-syncing the channel after a timeout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To use the online disk snapshot for online-backup, application-level consistency of the snapshot image is required. However, currently the guest agent can provide only filesystem-level consistency, and the snapshot may contain dirty data, for example, incomplete transactions. This patch provides the opportunity to quiesce applications before snapshot is taken. If --fsfreeze-hook option is specified, the hook is executed with "freeze" argument before the filesystem is frozen by fsfreeze-freeze command. As for fsfreeze-thaw command, the hook is executed with "thaw" argument after the filesystem is thawed.
