2021-07-14tcg/plugins: enable by default for most TCG buildsAlex Bennée
Aside from a minor bloat to file size the ability to have TCG plugins has no real impact on performance unless a plugin is actively loaded. Even then the libempty.so plugin shows only a minor degradation in performance caused by the extra book keeping the TCG has to do to keep track of instructions. As it's a useful feature lets just enable it by default and reduce our testing matrix a little. We need to move our linker testing earlier so we can be sure we can enable the loader module required. As we have ruled out static & plugins in an earlier patch we can also reduce the indent a little.

To have the jobs dispatched to custom runners, gitlab-runner must be installed, active as a service and properly configured. The variables file and playbook introduced here should help with those steps. The playbook introduced here covers the Linux distributions and has been primarily tested on OS/machines that the QEMU project has available to act as runners, namely: * Ubuntu 20.04 on aarch64 * Ubuntu 18.04 on s390x But, it should work on all other Linux distributions. Earlier versions were tested on FreeBSD too, so chances of success are high.

2021-07-14Jobs based on custom runners: documentation and configuration placeholderCleber Rosa
As described in the included documentation, the "custom runner" jobs extend the GitLab CI jobs already in place. One of their primary goals of catching and preventing regressions on a wider number of host systems than the ones provided by GitLab's shared runners. This sets the stage in which other community members can add their own machine configuration documentation/scripts, and accompanying job definitions. As a general rule, those newly added contributed jobs should run as "non-gating", until their reliability is verified (AKA "allow_failure: true").

The 'cpu' property is made available to the test object as well. For example, for a simple test as: def test(self): """ :avocado: tags=cpu:host """ self.assertEqual(self.cpu, "host") self.vm.launch() The resulting QEMU evocation will be like: qemu-system-x86_64 -display none -vga none \ -chardev socket,id=mon,path=/var/tmp/avo_qemu_sock_pdgzbgd_/qemu-1135557-monitor.sock \ -mon chardev=mon,mode=control -cpu host Reviewed-by: Cleber Rosa <crosa@redhat.com> Tested-by: Cleber Rosa <crosa@redhat.com> Reviewed-by: Willian Rampazzo <willianr@redhat.com> Signed-off-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Message-Id: <20210430133414.39905-2-wainersm@redhat.com> Signed-off-by: Cleber Rosa <crosa@redhat.com>
2021-07-13Acceptance Tests: support choosing specific distro and versionCleber Rosa
The tests based on the LinuxTest class give the test writer a ready to use guest operating system, currently pinned to Fedora 31. With this change, it's now possible to choose different distros and versions, similar to how other tags and parameter can be set for the target arch, accelerator, etc. One of the reasons for this work, is that some development features depend on updates on the guest side. For instance the tests on virtiofs_submounts.py, require newer kernels, and may benefit from running, say on Fedora 34, without the need for a custom kernel. Please notice that the pre-caching of the Fedora 31 images done during the early stages of `make check-acceptance` (before the tests are actually executed) are not expanded here to cover every new image added. But, the tests will download other needed images (and cache them) during the first execution.

2021-07-13i386: hardcode supported eVMCS version to '1'Vitaly Kuznetsov
Currently, the only eVMCS version, supported by KVM (and described in TLFS) is '1'. When Enlightened VMCS feature is enabled, QEMU takes the supported eVMCS version range (from KVM_CAP_HYPERV_ENLIGHTENED_VMCS enablement) and puts it to guest visible CPUIDs. When (and if) eVMCS ver.2 appears a problem on migration is expected: it doesn't seem to be possible to migrate from a host supporting eVMCS ver.2 to a host, which only support eVMCS ver.1. Hardcode eVMCS ver.1 as the result of 'hv-evmcs' enablement for now. Newer eVMCS versions will have to have their own enablement options (e.g. 'hv-evmcs=2').

2021-07-12qemu-img: Make unallocated part of backing chain obvious in mapEric Blake
The recently-added NBD context qemu:allocation-depth is able to distinguish between locally-present data (even when that data is sparse) [shown as depth 1 over NBD], and data that could not be found anywhere in the backing chain [shown as depth 0]; and the libnbd project was recently patched to give the human-readable name "absent" to an allocation-depth of 0. But qemu-img map --output=json predates that addition, and has the unfortunate behavior that all portions of the backing chain that resolve without finding a hit in any backing layer report the same depth as the final backing layer. This makes it harder to reconstruct a qcow2 backing chain using just 'qemu-img map' output, especially when using "backing":null to artificially limit a backing chain, because it is impossible to distinguish between a QCOW2_CLUSTER_UNALLOCATED (which defers to a [missing] backing file) and a QCOW2_CLUSTER_ZERO_PLAIN cluster (which would override any backing file), since both types of clusters otherwise show as "data":false,"zero":true" (but note that we can distinguish a QCOW2_CLUSTER_ZERO_ALLOCATED, which would also have an "offset": listing). The task of reconstructing a qcow2 chain was made harder in commit 0da9856851 (nbd: server: Report holes for raw images), because prior to that point, it was possible to abuse NBD's block status command to see which portions of a qcow2 file resulted in BDRV_BLOCK_ALLOCATED (showing up as NBD_STATE_ZERO in isolation) vs. missing from the chain (showing up as NBD_STATE_ZERO|NBD_STATE_HOLE); but now qemu reports more accurate sparseness information over NBD. An obvious solution is to make 'qemu-img map --output=json' add an additional "present":false designation to any cluster lacking an allocation anywhere in the chain, without any change to the "depth" parameter to avoid breaking existing clients. The iotests have several examples where this distinction demonstrates the additional accuracy.

2021-07-09qemu-img: Require -F with -b backing imageEric Blake
Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F), we deprecated the ability to create a file with a backing image that requires qemu to perform format probing. Qemu can still probe older files for backwards compatibility, but it is time to finish off the ability to create such images, due to the potential security risk they present. Update a couple of iotests affected by the change.

2021-07-06Deprecate pmem=on with non-DAX capable backend fileIgor Mammedov
It is not safe to pretend that emulated NVDIMM supports persistence while backend actually failed to enable it and used non-persistent mapping as fall back. Instead of falling-back, QEMU should be more strict and error out with clear message that it's not supported. So if user asks for persistence (pmem=on), they should store backing file on NVDIMM.

2021-07-05ui: Mark the '-no-quit' option as deprecatedThomas Huth
It's just a wrapper around the -display ...,window-close=off parameter, and the name "no-quit" is rather confusing compared to "window-close" (since there are still other means to quit the emulator), so we should rather tell our users to use the "window-close" parameter instead. While we're at it, update the documentation to state that "-no-quit" is available for GTK, too, not only for SDL. Reviewed-by: Daniel P.

2021-07-05ui: Fix the "-display sdl,window_close=..." parameterThomas Huth
According to the QAPI schema, there is a "-" and not a "_" between "window" and "close", and we're also talking about "window-close" in the long parameter description in qemu-options.hx, so we should make sure that we rather use the variant with the "-" by default instead of only allowing the one with the "_" here. The old way still stays enabled for compatibility, but we deprecate it, so that we can switch to a QAPIfied parameter one day more easily.

2021-07-05virtiofsd: Add an option to enable/disable posix aclsVivek Goyal
fuse has an option FUSE_POSIX_ACL which needs to be opted in by fuse server to enable posix acls. As of now we are not opting in for this, so posix acls are disabled on virtiofs by default. Add virtiofsd option "-o posix_acl/no_posix_acl" to let users enable/disable posix acl support. By default it is disabled as of now due to performance concerns with cache=none. Currently even if file server has not opted in for FUSE_POSIX_ACL, user can still query acl and set acl, and system.posix_acl_access and system.posix_acl_default xattrs show up listxattr response. Miklos said this is confusing. So he said lets block and filter system.posix_acl_access and system.posix_acl_default xattrs in getxattr/setxattr/listxattr if user has explicitly disabled posix acls using -o no_posix_acl. As of now continuing to keeping the existing behavior if user did not specify any option to disable acl support due to concerns about backward compatibility.

2021-07-05docs: describe the security considerations with virtiofsd xattr mappingDaniel P. Berrangé
Different guest xattr prefixes have distinct access control rules applied by the guest. When remapping a guest xattr care must be taken that the remapping does not allow the a guest user to bypass guest kernel access control rules. For example if 'trusted.*' which requires CAP_SYS_ADMIN is remapped to 'user.virtiofs.trusted.*', an unprivileged guest user which can write to 'user.*' can bypass the CAP_SYS_ADMIN control. Thus the target of any remapping must be explicitly blocked from read/writes by the guest, to prevent access control bypass. The examples shown in the virtiofsd man page already do the right thing and ensure safety, but the security implications of getting this wrong were not made explicit. This could lead to host admins and apps unwittingly creating insecure configurations. Signed-off-by: Daniel P.
