2012-05-01S390: fix kernel_commandline handlingChristian Borntraeger1-1/+1
The current handling of kernel parameters is broken. The pointer is always valid, even if no -kernel or -append is specified.

2012-05-01vga: Don't switch to 1 x 1 character text screenStefan Weil1-0/+4
Initially, vga_get_text_resolution returns a text resolution of 1 x 1 (vga register values are 0). This is visible during MIPS Malta boot with SDL. It also occurs with the i386 or x86_64 system emulation when it runs in single step mode: QEMU changes the size of the SDL window to the smallest possible value which is supported by the window manager. As this is not the calculated size, QEMU switches to scaled mode. When the BIOS or the VGA driver sets the normal text resolution, the window stays small and displays microscopic characters. Ignoring text resolutions of 1 x 1 or less avoids these problems. A similar workaround already exists for too large resolutions.

2012-05-01configure: Fix creation of symbolic links for MinGW toolchainStefan Weil1-11/+10
The MinGW toolchain on w32/w64 hosts does not create symbolic links, but implements 'ln -s' similar to 'cp -r'. In incremental out of tree builds, this resulted in files which were not updated when their counterparts in the QEMU source tree changed. Especially for Makefile* this happened very often. With this patch, the 'symlinked' files are now always updated for out of tree builds. Similar code was already used for the symbolic link of libcacard/Makefile. The symlink macro always removes the target before it is created again, therefore the rm command for libcacard/Makefile was redundant and is removed now. Macro symlink is also used with directories. To remove them on w32 hosts, a recursive rm is needed. v2: Quote arguments in shell function symlink, and also quote any argument which is passed to symlink and which contains macros. This should reduce the chance of accidents caused by rm -rf. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2012-04-30qemu-ga: persist tracking of fsfreeze state via filesystemMichael Roth2-47/+174
Currently, qemu-ga may die/get killed/go away for whatever reason after guest-fsfreeze-freeze has been issued, and before guest-fsfreeze-thaw has been issued. This means the only way to unfreeze the guest is via VNC/network/console access, but obtaining that access after-the-fact can often be very difficult when filesystems are frozen. Logins will almost always hang, for instance. In many cases the only recourse would be to reboot the guest without any quiescing of volatile state, which makes this a corner-case worth giving some attention to. A likely failsafe for this situation would be to use a watchdog to restart qemu-ga if it goes away. There are some precautions qemu-ga needs to take in order to avoid immediately hanging itself on I/O, however, namely, we must disable logging and defer to processing/creation of user-specific logfiles, along with creation of the pid file if we're running as a daemon. We also need to disable non-fsfreeze-safe commands, as we normally would when processing the guest-fsfreeze-freeze command. To track when we need to do this in a way that persists between multiple invocations of qemu-ga, we create a file on the guest filesystem before issuing the fsfreeze, and delete it when doing the thaw. On qemu-ga startup, we check for the existance of this file to determine the need to take the above precautions. We're forced to do it this way since a more traditional approach such as reading/writing state to a dedicated state file will cause access/modification time updates, respectively, both of which will hang if the file resides on a frozen filesystem. Both can occur even if relatime is enabled. Checking for file existence will not update the access time, however, so it's a safe way to check for fsfreeze state. An actual watchdog-based restart of qemu-ga can itself cause an access time update that would thus hang the invocation of qemu-ga, but the logic to workaround that can be handled via the watchdog, so we don't address that here (for relatime we'd periodically touch the qemu-ga binary if the file $qga_statedir/qga.state.isfrozen is not present, this avoids qemu-ga updates or the 1 day relatime threshold causing an access-time update if we try to respawn qemu-ga shortly after it goes away) Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2012-04-30qemu-ga: add a whitelist for fsfreeze-safe commandsMichael Roth5-33/+140
Currently we rely on fsfreeze/thaw commands disabling/enabling logging then having other commands check whether logging is disabled to avoid executing if they aren't safe for running while a filesystem is frozen. Instead, have an explicit whitelist of fsfreeze-safe commands, and consolidate logging and command enablement/disablement into a pair of helper functions: ga_set_frozen()/ga_unset_frozen() Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2012-04-30qemu-ga: improve recovery options for fsfreezeMichael Roth2-64/+101
guest-fsfreeze-thaw relies on state information obtained from guest-fsfreeze-freeze to determine what filesystems to unfreeze. This is unreliable due to the fact that that state does not account for FIFREEZE being issued by other processes, or previous instances of qemu-ga. This means in certain situations we cannot thaw filesystems even with a responsive qemu-ga instance at our disposal. This patch allows guest-fsfreeze-thaw to be issued unconditionally. It also adds some additional logic to allow us to thaw filesystems regardless of how many times the filesystem's "frozen" refcount has been incremented by any guest processes. Also, guest-fsfreeze-freeze now operates atomically: on success all freezable filesystems are frozen, and on error all filesystems are thawed. The ambiguous "GUEST_FSFREEZE_STATUS_ERROR" state is no longer entered. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
