* xenstored: Fix socket-based connection teardown. Reading zero byteskfraser@localhost.localdomain2007-07-251-0/+6
| | | | | | *should* in fact cause the connection to be destroyed. Fix this with a little extra code in the readfd() handler. Signed-off-by: Keir Fraser <keir@xensource.com>

| | | | | | | | 1. readfd/writefd account for EINTR/EAGAIN errno returns. 2. Handle zero return from ->read() and ->write() handlers symmetrically. 3. Fix some indentation issues (use hard tabs). Signed-off-by: Keir Fraser <keir@xensource.com>
* Add domain name check and UUID check to 'xm new' command.kfraser@localhost.localdomain2007-07-241-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | Add a domain name check and a UUID check to xm new command. The check logic is as follows: - If the UUID is not specified - If a VM with same name exists => Update the config for that existing VM - Else no vm with same name exists => Define a brand new VM with auto-generated UUID - Else UUID is specified - If a VM with same UUID exists - If name is different => Error - Else if name is same => Update the config for that existing VM - Else no VM with same UUID exists - If name is different => Define a branch new VM with that name - Else if name is same => Error Signed-off-by: Masaki Kanno <kanno.masaki@jp.fujitsu.com>

* [PVFB] Fix shift key for graphical vnc displaykfraser@localhost.localdomain2007-07-231-3/+103
| | | | | | | | | | | | | There is a problem in the input of the key in the VNC connection on the PV domain. When client's keyboard is not the same as the kind of the keyboard of PVFB and GuestOS, it is not possible to input it correctly. This patch handled the state of shift from the set keymap.

* [IOEMU] Fix shift key for graphical vnc displaykfraser@localhost.localdomain2007-07-232-8/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem in the input of the key in the VNC connection on the HVM domain. When client's keyboard is not the same as the kind of the keyboard of qemu-dm and GuestOS, it is not possible to input it correctly. VNC client qemu-dm & GuestOS --------------+----------------------- ja en-us ==> NG en-us en-us ==> OK Originally, the same keysym-code between client and qemu-dm is transmitted. However, even if it is the same character, the state of shift is different according to the kind of keyboard. ex. "=" charactor --------------------- en-us : "=" ja : shift + "-" Therefore, it is necessary to handle the state of the shift by setting qemu-dm and GuestOS. There is information on whether shift is necessary for each key for the keymap of qemu-dm. ex. VNC client : ja qemu-dm & GuestOS : en-us input key : "=" event client to qemu-dm : shift(push) >> "="(push) >> "="(release) >> shift(release) event qemu-dm to guest : shift(push) >> shift(release) >> "="(push) >> "="(release) >> shift(push) >> shift(release) This patch handled the state of shift from the set keymap. When client's keyboard is not same as the kind of qemu-dm/GuestOS, it is possible to input it correctly. It was confirmed to input it correctly mutually with this patch between en-us and ja.

* [xend / libxen] Add support for labeling of virtual network interfaces.kfraser@localhost.localdomain2007-07-1915-22/+312
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds labeling of virtual network interfaces to xend and makes this manageable through the Xen-API. It's a feature that is only usable if ACM is enabled in Xen and xend is used through the xen-api. A labeled virtual network interface will be plugged into a bridge where other domains with the same-labeled network interface are connected to, so that only same-colored domains can communicate with each other. The bridge should be connected to the outside world using VLAN for isolation, extending the isolation beyond the local machine. If a virtual machine is labeled with a VM label that only has one Simple Type Enforcement Type then it is not necessary to label the virtual network interface, but the color of the network interface is determined from the VM's label. If, however, a virtual machine is labeled with a VM label that has multiple Simple Type Enforcement Types, then the explicit labeling of each virtual network interface is required. To specify the label of a network interface, the vif line in the VM's configuration file has been extended with parameters similar use for specifying the label of the VM: vif = ['policy=<policy name>,label=<resource label>'] This labels the VIF of the virtual machine for usage under the policy 'policy name' and labels it with the label 'resource label'.

| * Make QEMU consistently report write caching support for emulated IDEkfraser@localhost.localdomain2007-07-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drives to fix a hang during SLES 9 HVM guest installation. Without this, the SLES 9 installer kernels (32 and 64 bit) were getting inconsistent information from QEMU as to whether the (emulated) IDE drives support write caching (which they do). So part of the kernel thought write caching was enabled (and enabled the usage of barrier writes) and part of it didn't, which triggered a bug in which the same barrier write is submitted over and over again ... Fixed by setting another bit in the WIN_IDENTIFY (IDE drive "identify" command) response to indicate we really, truly support write caching.

| * [Xen-API] Extension of the Xen-API for managing Xen Security Policieskfraser@localhost.localdomain2007-07-0915-155/+3408
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements extensions for managing security policies in xend. The XSPolicy and ACMPolicy classes provide the interface for the Xen-API and implement functionality for setting, updating and activating of a Xen security policy as well as labeling of virtual machines and resources such as block devices. Labeling of network devices will follow. The acmpolicy class implements a compiler for translating an XML policy into their binary format and provides functionality for comparing a current policy against a new one when changing/updating a policy. The xspolicyadmin class administers the policy of the system. Some of the xend-internal code deals with transforming the labeling information from the S-Expression format into the new Xen-API format. This is similar to much of the other code that is already there. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
