2014-02-17Use error_is_set() only when necessaryMarkus Armbruster
error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Dumb it down to obvious. Gets rid of several dozen Coverity false positives. Note that the obvious form is already used in many places.

2013-11-22qemu-ga: vss-win32: Install VSS provider COM+ application serviceTomoki Sekiyama
Currently, qemu-ga for Windows fails to execute guset-fsfreeze-freeze when no user is logging in to Windows, with an error message: {"error":{"class":"GenericError", "desc":"failed to add C:\\ to snapshotset: (error: 8004230f)"}} To enable guest-fsfreeze-freeze/thaw without logging in users, this installs a service to execute qemu-ga VSS provider COM+ application that has full access privileges to the local system. The service will automatically be removed when the COM+ application is deregistered. This patch replaces ICOMAdminCatalog interface with ICOMAdminCatalog2 interface that contains CreateServiceForApplication() method in addition.

2013-11-16qga: Fix shutdown command of guest agent to work with SysVwhitearchey
For now guest agent uses following command to shutdown system: shutdown -P +0 "blabla" but this syntax works only with shutdown command from systemd or upstart, because SysV shutdown requires -h switch. Following patch changes the command so it works with systemd, upstart and SysV With upstart/systemd qga use one of thee commands, depending on 'mode' parameter: shutdown -P +0 "..." shutdown -H +0 "..." shutdown -r +0 "..." SysV equivalents for these are: shutdown -h -P +0 "..." shutdown -h -H +0 "..." shutdown -h -r +0 "..." and these retain their meaning with upstart/systemd. According to FreeBSD manpages, shutdown does not accept -P and -H options. Commands should be: shutdown -p +0 "..." shutdown -h +0 "..." shutdown -r +0 "..." shutdown in Solaris does not accept any of -hHpPr and does not accept time in "+0" format Signed-off-by: Michael Avdienko <whitearchey@gmail.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

2013-09-09qemu-ga: Add Windows VSS provider and requester as DLLTomoki Sekiyama
Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).

The qemu guest agent creates a bunch of files with insecure permissions when started in daemon mode. For example: -rw-rw-rw- 1 root root /var/log/qemu-ga.log -rw-rw-rw- 1 root root /var/run/qga.state -rw-rw-rw- 1 root root /var/log/qga-fsfreeze-hook.log In addition, at least all files created with the "guest-file-open" QMP command, and all files created with shell output redirection (or otherwise) by utilities invoked by the fsfreeze hook script are affected. For now mask all file mode bits for "group" and "others" in become_daemon(). Temporarily, for compatibility reasons, stick with the 0666 file-mode in case of files newly created by the "guest-file-open" QMP call. Do so without changing the umask temporarily.

2013-03-11qemu-ga: use key-value store to avoid recycling fd handles after restartMichael Roth
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.
