[PATCH 0/9] Fix image labels lost after migration with shared fs
by Peng Liang 10 Sep '21

10 Sep '21

When migrating using shared fs, the dst host will remember the image labels again before launching the VM and the src host will remove the image labels after migration. It leads to that the image labels lost after migration. Patch 7-9 are the real fix patches. Peng Liang (9): security: add virSecurityUpdateTimestampIfexists security: add virSecurityManagerUpdateImageLabel security: implement domainUpdateSecurityImageLabel for stack security: implement domainUpdateSecurityImageLabel for DAC qemu: add qemuSecurityUpdateImageLabel security: rename virSecurityDACSetImageLabelInternal to virSecurityDACSetImageLabelSingle migration: don't remember image labels when migrating with shared fs migration: don't remove image labels after migration migration: update image labels in dst after migration src/libvirt_private.syms | 1 + src/qemu/qemu_migration.c | 12 +++++++ src/qemu/qemu_process.c | 5 ++- src/qemu/qemu_security.c | 10 ++++++ src/qemu/qemu_security.h | 5 +++ src/security/security_dac.c | 58 +++++++++++++++++++++++++-------- src/security/security_driver.h | 5 +++ src/security/security_manager.c | 29 +++++++++++++++++ src/security/security_manager.h | 5 +++ src/security/security_stack.c | 20 ++++++++++++ src/security/security_util.c | 32 ++++++++++++++++++ src/security/security_util.h | 4 +++ 12 files changed, 172 insertions(+), 14 deletions(-) -- 2.31.1

[libvirt PATCH v3 0/7] Enable autostarting mediated devices
by Jonathon Jongsma 09 Sep '21

09 Sep '21

This first version of this series was reviewed quite a while ago and all patches were ACKed except the second one. I posted a second series with changes noted below but it was never ACKed and I dropped the ball for a little while. Subsequently there were questions about whether physical devices (e.g. pci, usb, etc) should return 'true' or 'false' for the GetAutostart()/IsPersistent() calls. I had initially marked them as persistent=true and autostart=true because they superficially act a bit like persistently-defined devices. But Boris convinced me that this is not a very accurate classification since if the physical device is unplugged, there will be no record of it left behind. So I've switched all non-mdev devices to be persistent=false and autostart=false. This is also imperfect, but it seems relatively harmless. Comments welcome. A reminder of what is included in this series: - new API consistent with existing libvirt objects: - virNodeDeviceGetAutostart() - virNodeDeviceSetAutostart() - virNodeDeviceIsPersistent() - virNodeDeviceIsActive - new virsh commands - nodedev-info - nodedev-autostart Changes in version 2: - Parse the autostart property from mdevctl output. Changes in version 3: - switch physical devices to autostart=false, persistent=false - rebase to upstream - update version numbers for new API, etc - fix accidental copy-paste error in virsh command descriptions Jonathon Jongsma (7): api: add virNodeDevice(Get|Set)Autostart() nodedev: implement virNodeDevice(Get|Set)Autostart() nodedev: Add tests for mdevctl autostart command virsh: add nodedev-autostart api: add virNodeDeviceIsPersistent()/IsActive() nodedev: Implement virNodeDeviceIsPersistent()/IsActive() virsh: add nodedev-info docs/manpages/virsh.rst | 27 +++ include/libvirt/libvirt-nodedev.h | 10 + src/conf/node_device_conf.h | 1 + src/conf/virnodedeviceobj.c | 16 ++ src/conf/virnodedeviceobj.h | 6 + src/driver-nodedev.h | 18 ++ src/libvirt-nodedev.c | 141 +++++++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 4 + src/node_device/node_device_driver.c | 189 +++++++++++++++++- src/node_device/node_device_driver.h | 19 ++ src/node_device/node_device_udev.c | 22 +- src/remote/remote_driver.c | 6 +- src/remote/remote_protocol.x | 60 +++++- src/remote_protocol-structs | 26 +++ .../nodedevmdevctldata/mdevctl-autostart.argv | 8 + tests/nodedevmdevctltest.c | 55 +++++ tools/virsh-nodedev.c | 139 +++++++++++++ 18 files changed, 740 insertions(+), 9 deletions(-) create mode 100644 tests/nodedevmdevctldata/mdevctl-autostart.argv -- 2.31.1

[PATCHv4 0/9] ch: Add Console support
by William Douglas 09 Sep '21

09 Sep '21

This series enables console support in the cloud-hypervisor driver. Cloud-hypervisor only supports a single console or serial device at a time, hence the checks to ensure the domain configuration is only passing one or the other. Changes since v3: * Reset ch monitor's curl handle after a get info request * Improved PTY validation logic * Updated deviceValidateCallback to handle PTY validation * Added error reporting for unexpected PTY json data * Dropped the parallels scanning for PTY * Added a fix for handling deviceValidateCallback failures Changes since v2: * Squashed an additional patch. Changes since v1: * Added missing patch to add the virChrdev device * Added handling for multiple curl WRITEFUNCTION call backs * Added missing free for data.content * Removed redundant console configuration check * Improved handling of pty JSON data to make use of g_autoptr * Squashed two patches William Douglas (9): ch_domain: Add virChrdevs for console support ch_monitor: Make unused function static ch_monitor: Update virCHMonitorGet to handle accept a response ch_monitor: Use virCHMonitorGet to access cloud-hypervisor API ch_monitor: Add pty json builder function ch_process: Handle enabled console devices ch_domain: Allow controller and chr devices ch_driver: Add handler for console API ch_driver: Handle validation failure correctly src/ch/ch_domain.c | 40 +++++++++++++++++++- src/ch/ch_domain.h | 3 ++ src/ch/ch_driver.c | 76 ++++++++++++++++++++++++++++++++++++- src/ch/ch_monitor.c | 91 +++++++++++++++++++++++++++++++++++++++++++-- src/ch/ch_monitor.h | 3 ++ src/ch/ch_process.c | 84 +++++++++++++++++++++++++++++++++++++++++ 6 files changed, 290 insertions(+), 7 deletions(-) -- 2.31.1

[PATCH 00/24] virstoragetest: Re-instate testing of images without backing format
by Peter Krempa 09 Sep '21

09 Sep '21

Most of the series are refactors to make virstoragetest less archaic, the last commit then re-introduces testing of images which don't have backing format recorded in the metadata which can't be formatted using qemu-img any more but have security implications if we'd mishandle them. Peter Krempa (24): virstoragetest: Drop testing of RBD backends via parsing real images virstoragetest: Drop testing of NBD backends via parsing real images testutils: Introduce helper for stripping bulilddir/srcdir from test outputs virstoragetest: Store output of TEST_CHAIN in output files virstoragetest: Remove redundant arguments for chain lookup tests virstoragetest: Rework TEST_LOOKUP* cases to work on fake backing chain virstoragetest: Test backing chain loops with hardcoded images virstoragetest: Use existing directory in the source tree for 'directory' probing tests

missing backing store virstoragetest: Use existing file for testing 'raw' image lookup virstoragetest: Convert symlink and relative image testing use preformatted images virstoragetest: Use
