2011-12-19qom: introduce QERR_PROPERTY_VALUE_OUT_OF_RANGEPaolo Bonzini1-0/+3
This will be used when reject invalid values for integer fields that are less than 64-bits wide. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: add new dynamic property infrastructure based on Visitors (v2)Anthony Liguori1-0/+3
qdev properties are settable only during construction and static to classes. This isn't flexible enough for QOM. This patch introduces a property interface for qdev that provides dynamic properties that are tied to objects, instead of classes. These properties are Visitor based instead of string based too.

2011-12-12guest agent: add RPC blacklist command-line optionMichael Roth1-0/+3
This adds a command-line option, -b/--blacklist, that accepts a comma-seperated list of RPCs to disable, or prints a list of available RPCs if passed "?". In consequence this also adds general blacklisting and RPC listing facilities to the new QMP dispatch/registry facilities, should the QMP monitor ever have a need for such a thing. Ideally, to avoid support/compatability issues in the future, blacklisting guest agent functionality will be the exceptional case, but we add the functionality here to handle guest administrators with specific requirements.

2011-10-04qerror: add qerror_report_err()Anthony Liguori1-0/+2
This provides a bridge between Error (new error mechanism) and QError (old error mechanism). Errors can be propagated whereas QError cannot. The minor evilness avoids layering violations. Since QError should go away RSN, it seems like a reasonable hack. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-09-15Monitor/QMP: Don't allow cont on bad VM stateLuiz Capitulino1-0/+3
We have two states where issuing cont before system_reset can cause problems: RSTATE_SHUTDOWN (when -no-shutdown is used) and RSTATE_PANICKED (which only happens with kvm). This commit fixes that by doing the following when state is RSTATE_SHUTDOWN or RSTATE_PANICKED: 1. returning an error to the user/client if cont is issued 2. automatically transition to RSTATE_PAUSED during system_reset Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-07-23Introduce a 'client_add' monitor command accepting an open FDDaniel P. Berrange1-0/+3
Allow client connections for VNC and socket based character devices to be passed in over the monitor using SCM_RIGHTS. One intended usage scenario is to start QEMU with VNC on a UNIX domain socket. An unprivileged user which cannot access the UNIX domain socket, can then connect to QEMU's VNC server by passing an open FD to libvirt, which passes it onto QEMU. { "execute": "get_fd", "arguments": { "fdname": "myclient" } } { "return": {} } { "execute": "add_client", "arguments": { "protocol": "vnc", "fdname": "myclient", "skipauth": true } } { "return": {} } In this case 'protocol' can be 'vnc' or 'spice', or the name of a character device (eg from -chardev id=XXXX) The 'skipauth' parameter can be used to skip any configured VNC authentication scheme, which is useful if the mgmt layer talking to the monitor has already authenticated the client in another way. * console.h: Define 'vnc_display_add_client' method * monitor.c: Implement 'client_add' command * qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method * qerror.c, qerror.h: Add QERR_ADD_CLIENT_FAILED * qmp-commands.hx: Declare 'client_add' command * ui/vnc.c: Implement 'vnc_display_add_client' method Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-10-03Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil1-2/+1
Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).

2010-07-30migration: Accept 'cont' only after successful incoming migrationAmit Shah1-0/+3
When a 'cont' is issued on a VM that's just waiting for an incoming migration, the VM reboots and boots into the guest, possibly corrupting its storage since it could be shared with another VM running elsewhere. Ensure that a VM started with '-incoming' is only run when an incoming migration successfully completes. A new qerror, QERR_MIGRATION_EXPECTED, is added to signal that 'cont' failed due to no incoming migration has been attempted yet.

2010-03-16error: Infrastructure to track locations for error reportingMarkus Armbruster1-1/+3
New struct Location holds a location. So far, the only location is LOC_NONE, so this doesn't do anything useful yet. Passing the current location all over the place would be too cumbersome. Hide it away in static cur_loc instead, and provide accessors. Print it in error_report(). Store it in QError, and print it in qerror_print(). Store it in QemuOpt, for use by qemu_opts_foreach(). This makes error_report() do the right thing when it runs within qemu_opts_foreach(). We may still have to store it in other data structures holding user input for better error messages. Left for another day.
