* nbd: allow authorization with nbd-server-start QMP commandDaniel P. Berrange2019-03-064-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As with the previous patch to qemu-nbd, the nbd-server-start QMP command also needs to be able to specify authorization when enabling TLS encryption. First the client must create a QAuthZ object instance using the 'object-add' command: { 'execute': 'object-add', 'arguments': { 'qom-type': 'authz-list', 'id': 'authz0', 'parameters': { 'policy': 'deny', 'rules': [ { 'match': '*CN=fred', 'policy': 'allow' } ] } } } They can then reference this in the new 'tls-authz' parameter when executing the 'nbd-server-start' command: { 'execute': 'nbd-server-start', 'arguments': { 'addr': { 'type': 'inet', 'host': '127.0.0.1', 'port': '9000' }, 'tls-creds': 'tls0', 'tls-authz': 'authz0' } } Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Daniel P.

* qemu-nbd: add support for authorization of TLS clientsDaniel P. Berrange2019-03-066-12/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently any client which can complete the TLS handshake is able to use the NBD server. The server admin can turn on the 'verify-peer' option for the x509 creds to require the client to provide a x509 certificate. This means the client will have to acquire a certificate from the CA before they are permitted to use the NBD server. This is still a fairly low bar to cross. This adds a '--tls-authz OBJECT-ID' option to the qemu-nbd command which takes the ID of a previously added 'QAuthZ' object instance. This will be used to validate the client's x509 distinguished name. Clients failing the authorization check will not be permitted to use the NBD server. For example to setup authorization that only allows connection from a client whose x509 certificate distinguished name is CN=laptop.example.com,O=Example Org,L=London,ST=London,C=GB escape the commas in the name and use: qemu-nbd --object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\ endpoint=server,verify-peer=yes \ --object 'authz-simple,id=auth0,identity=CN=laptop.example.com,,\ O=Example Org,,L=London,,ST=London,,C=GB' \ --tls-creds tls0 \ --tls-authz authz0 \ ....other qemu-nbd args...

| * virtio-balloon: VIRTIO_BALLOON_F_FREE_PAGE_HINTWei Wang2019-03-062-1/+290
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new feature enables the virtio-balloon device to receive hints of guest free pages from the free page vq. A notifier is registered to the migration precopy notifier chain. The notifier calls free_page_start after the migration thread syncs the dirty bitmap, so that the free page optimization starts to clear bits of free pages from the bitmap. It calls the free_page_stop before the migration thread syncs the bitmap, which is the end of the current round of ram save. The free_page_stop is also called to stop the optimization in the case when there is an error occurred in the process of ram saving. Note: balloon will report pages which were free at the time of this call. As the reporting happens asynchronously, dirty bit logging must be enabled before this free_page_start call is made. Guest reporting must be disabled before the migration dirty bitmap is synchronized. Signed-off-by: Wei Wang <wei.w.wang@intel.com> CC: Michael S.

| * migration/ram.c: add the free page optimization enable flagWei Wang2019-03-062-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the free page optimization enable flag, and a function to set this flag. When the free page optimization is enabled, not all the pages are needed to be sent in the bulk stage. Why using a new flag, instead of directly disabling ram_bulk_stage when the optimization is running? Thanks for Peter Xu's reminder that disabling ram_bulk_stage will affect the use of compression. Please see save_page_use_compression. When xbzrle and compression are used, if free page optimizaion causes the ram_bulk_stage to be disabled, save_page_use_compression will return false, which disables the use of compression. That is, if free page optimization avoids the sending of half of the guest pages, the other half of pages loses the benefits of compression in the meantime. Using a new flag to let migration_bitmap_find_dirty skip the free pages in the bulk stage will avoid the above issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, qemu_ram_foreach_* calls RAMBlockIterFunc with many block-specific arguments. But often iter func needs RAMBlock*. This refactoring is needed for fast access to RAMBlock flags from qemu_ram_foreach_block's callback. The only way to achieve this now is to call qemu_ram_block_from_host (which also enumerates blocks). So, this patch reduces complexity of qemu_ram_foreach_block() -> cb() -> qemu_ram_block_from_host() from O(n^2) to O(n). Fix RAMBlockIterFunc definition and add some functions to read RAMBlock* fields witch were passed.
