[PATCH] docs: manpages: Strip table of contents from manpages
by Peter Krempa 23 Sep '20

23 Sep '20

After meson conversion the man pages started to contain the table of contents. In autoconf we prevented this by a 'grep -v ::contents' in the command building the manpages. A more cultured solution is to strip out the 'contents' docutils element directly. Reported-by: Daniel P.

[PATCH v2] docs/system: clarify deprecation schedule
by Stefan Hajnoczi 23 Sep '20

23 Sep '20

The sentence explaining the deprecation schedule is ambiguous. Make it clear that a feature deprecated in the Nth release is guaranteed to remain available in the N+1th release. Removal can occur in the N+2nd release or later. As an example of this in action, see commit 25956af3fe5dd0385ad8017bc768a6afe41e2a74 ("block: Finish deprecation of 'qemu-img convert -n -o'"). The feature was deprecated in QEMU 4.2.0. It was present in the 5.0.0 release and removed in the 5.1.0 release. Suggested-by: Daniel P.

[PATCH v2] util: support PCI passthrough net device stats collection
by zhenwei pi 23 Sep '20

23 Sep '20

Collect PCI passthrough net device stats from kernel by netlink API. Currently, libvirt can not get PCI passthrough net device stats, run command: #virsh domifstat instance --interface=52:54:00:2d:b2:35 error: Failed to get interface stats instance 52:54:00:2d:b2:35 error: internal error: Interface name not provided The PCI device(usually SR-IOV virtual function device) is detached while it's used in PCI passthrough mode. And we can not parse this device from /proc/net/dev any more. In this patch, libvirt check net device is VF of not firstly, then query virNetDevVFInterfaceStats(new API). virNetDevVFInterfaceStats parses VFs info of all PFs, compares MAC address until the two MAC addresses match. '#ip -s link show' can get the same result. Instead of parsing the output result, implement this feature by libnl API. Notice that this feature deponds on driver of PF. Test on Mellanox ConnectX-4 Lx, it works well. Also test on Intel Corporation 82599ES, it works, but only get 0. (ip-link command get the same result).

[libvirt PATCH] tests: Don't advertise VIR_TEST_EXPENSIVE to users
by Andrea Bolognani 23 Sep '20

23 Sep '20

Right now, the logic that takes care of deciding whether expensive tests should be run or not is not working correctly: more specifically, it's not possible to use something like $ VIR_TEST_EXPENSIVE=1 ninja test to override the default choice, because in meson.build we always pass an explicit value that overrides whatever is present in the environment. We could implement logic to make this work properly, but that would require some refactoring of our test infrastructure and is arguably of little value given that running $ meson build -Dexpensive_tests=enabled is very fast, so let's just stop telling users about the variable instead and call it a day.

[PATCH 0/2] Add unit test for timer validation
by Sebastian Mitterle 22 Sep '20

22 Sep '20

In v1, the minimal test case is moved to the existing test suite qemuxml2argv. Support for error message checking is added. The error message expectations for existing test cases have not been validated and reflect the current state. Localization suppression was tested manually by running the test suite executable with a different locale that should have made one of the tests fail if it had been localized. Requiring the an expected failure to have an error was tested manually by using the original qemuxml2argvmock that didn't create an error message.

[PATCH v6 0/3] bhyve: support 'isa' controller for LPC
by Roman Bogorodskiy 22 Sep '20

22 Sep '20

Changes since v5: Added patch 3/3 to allow to use slot 1 for devices other than LPC. Technically, it can be squashed into the second patch, but this way it should be easier to review; I can squash it before merging, but I also it's probably self-contained enough to stay separated. No changes in 1-2/3 except rebasing.

[PATCH v1 0/4] revert latest PPC64 NVDIMM changes
by Daniel Henrique Barboza 22 Sep '20

22 Sep '20

Hi, In [1], Daniel pointed out that the changes made by [2] are uncompliant with the Libvirt design of not doing anything that can compromise guests in the wild. This series aims to solve that by reverting the changes made by [2]. It also enhances the auto-alignment of ppc64 NVDIMM in a way that we can have consistency between the sizes reported in the domain XML and what QEMU will see, while not hurting any running guests that are already using the auto-alignment feature. For simplicity, first patch contains the revert of all relevant patches from [2] in a single commit. [1] https://www.redhat.com/archives/libvir-list/2020-September/msg00572.html [2] https://www.redhat.com/archives/libvir-list/2020-July/msg02010.html Daniel Henrique Barboza (4): qemu: revert latest pSeries NVDIMM design changes conf, qemu: move qemuDomainNVDimmAlignSizePseries to domain_conf.c domain_conf.c: auto-align pSeries NVDIMM in virDomainMemoryDefParseXML() NEWS.rst: document the pSeries NVDIMM auto-alignment revival NEWS.rst | 12 ++++ docs/formatdomain.rst | 6 +- src/conf/domain_conf.c | 71 +++++++++++++++---- src/conf/domain_conf.h | 3 + src/libvirt_private.syms | 1 + src/qemu/qemu_domain.c | 19 +++-- src/qemu/qemu_domain.h | 6 +- src/qemu/qemu_hotplug.c | 6 +- src/qemu/qemu_validate.c | 42 ++--------- ...ory-hotplug-nvdimm-ppc64.ppc64-latest.args | 2 +- .../memory-hotplug-nvdimm-ppc64.xml | 2 +- .../memory-hotplug-nvdimm-ppc64.xml | 2 +- 12 files changed, 105 insertions(+), 67 deletions(-) -- 2.26.2

[PATCH] util: support PCI passthrough net device stats collection
by zhenwei pi 22 Sep '20

22 Sep '20

Collect PCI passthrough net device stats from kernel by netlink API. Currently, libvirt can not get PCI passthrough net device stats, run command: #virsh domifstat instance --interface=52:54:00:2d:b2:35 error: Failed to get interface stats instance 52:54:00:2d:b2:35 error: internal error: Interface name not provided The PCI device(usually SR-IOV virtual function device) is detached while it's used in PCI passthrough mode. And we can not parse this device from /proc/net/dev any more. In this patch, libvirt check net device is VF of not firstly, then query virNetDevVFInterfaceStats(new API). virNetDevVFInterfaceStats parses VFs info of all PFs, compares MAC address until the two MAC addresses match. '#ip -s link show' can get the same result. Instead of parsing the output result, implement this feature by libnl API. Notice that this feature deponds on driver of PF. Test on Mellanox ConnectX-4 Lx, it works well. Also test on Intel Corporation 82599ES, it works, but only get 0. (ip-link command get the same result).

[libvirt PATCH] tests: don't mix FILE* and UNIX FD I/O on same stream
by Daniel P. Berrangé 21 Sep '20

21 Sep '20

There is currently a hand in test27 that exhibits itself on FreeBSD 11.4 only. The behaviour is that virCommandProcessIO gets POLLIN on the FD for stdout, but read() blocks. Meanwhile commandtest also blocks in write for stderr because the pipe buffers are full. This fix in commandhelper likely does not really address the root cause just hides it due to the buffering done by FILE *. Mixing UNIX FD I/O and FILE * I/O is bad practice regardles.

[PATCH v5 0/8] Configurable policy for handling deprecated interfaces
by Markus Armbruster 21 Sep '20

21 Sep '20

New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<in-policy> configures what to do when deprecated input is received. Available policies: * accept: Accept deprecated commands and arguments (default) * reject: Reject them * crash: Crash -compat deprecated-output=<out-policy> configures what to do when deprecated output is sent. Available output policies: * accept: Emit deprecated command results and events (default) * hide: Suppress them For now, -compat covers only deprecated syntactic aspects of QMP. We may want to extend it to cover semantic aspects, CLI, and experimental features. v5: * Old PATCH 01-26 merged in commit f57587c7d47. * Rebased, non-trivial conflicts in PATCH 1 due to Meson, and in PATCH 7 due to visitor changes * PATCH 1: Comments updated for 5.2 [Eric] * PATCH 2: Harmless missing initialization fixed [Eric] * PATCH 3+4: Harmless missing has_FOO = true fixed [Eric] * PATCH 6+7: Commit message tweaked v4: * PATCH 05+07: Temporary memory leak plugged [Marc-André] * PATCH 23: Rewritten [Marc-André] * PATCH 24: Comment typo [Marc-André] * PATCH 30: Memory leaks plugged v3: * Rebased, non-trivial conflicts in PATCH 01+26+27+34 due to RST conversion and code motion * PATCH 28-29: Old PATCH 28 split up to ease review * PATCH 30-31: New * PATCH 32-33: Old PATCH 29 split up to ease review Comparison to RFC (24 Oct 2019): * Cover arguments and results in addition to commands and events * Half-baked "[RFC PATCH 18/19] qapi: Include a warning in the response to a deprecated command" dropped See also last item of Subject: Minutes of KVM Forum BoF on deprecating stuff Date: Fri, 26 Oct 2018 16:03:51 +0200 Message-ID: <87mur0ls8o.fsf(a)dusky.pond.sub.org> https://lists.nongnu.org/archive/html/qemu-devel/2018-10/msg05828.html Cc: Lukáš Doktor <ldoktor(a)redhat.com> Cc: libguestfs(a)redhat.com Cc: libvir-list(a)redhat.com Cc: Daniel P.

[PATCH v3 0/6] qemu: implementation of transient disk option
by Masayoshi Mizuma 19 Sep '20

19 Sep '20

This patchset tries to implement transient option for qcow2 and raw format disk. It gets user available to set <transient/> to the domain xml file like as: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/guest.qcow2'/> <target dev='vda' bus='virtio'/> <transient/> </disk> Any changes which the Guest does to the disk is dropped when the Guest is shutdowned. There are some limitations for transient disk option so far: - Supported disk format is qcow2 and raw - blockdev capability is required for qemu - Following features are blocked with transient disk option - blockjobs - Migration - Disk hotplug Masayoshi Mizuma (6): qemu: Block blockjobs when transient disk option is enabled qemu: Block disk hotplug when transient disk option is enabled qemu: Block migration when transient disk option is enabled qemu: update the validation for transient disk option qemu: Introduce to handle transient disk qemu: Add transient disk handler to start and stop the guest src/qemu/qemu_domain.c | 7 +++ src/qemu/qemu_hotplug.c | 6 +++ src/qemu/qemu_migration.c | 10 ++++ src/qemu/qemu_process.c | 10 ++++ src/qemu/qemu_snapshot.c | 103 +++++++++++++++++++++++++++++++++++--- src/qemu/qemu_snapshot.h | 5 ++ src/qemu/qemu_validate.c | 25 ++++++++- src/util/virstoragefile.c | 2 + src/util/virstoragefile.h | 4 ++ 9 files changed, 164 insertions(+), 8 deletions(-) -- 2.27.0

[libvirt PATCH 0/3] cpu: Make unknown XML elements fail CPU comparison
by Tim Wiederhake 18 Sep '20

18 Sep '20

We currently ignore unknown elements in the CPU XML description, e.g. with vi= rsh cpu-compare and hypervisor-cpu-compare. This makes '<cpu><faeture name=3D"...= "/></cpu>' (note the typo in "faeture") semantically identic to '<cpu/>'. No error is re= ported. This series adds checks for unrecognized attributes and elements in the "<cpu= >" element, catching this kind of mistake. An alternative approach to this problem would be to create a new schema, whic= h might turn out awkward as cpu-compare and hypervisor-cpu-compare accept a wide rang= e of cpu descriptions, including full domain, capabilities, and domainCapabilities= XML. Tim Wiederhake (3): tests: Allow cpuTestLoadXML to fail for the guest if we expect it the test to fail tests: Ensure that cpu comparison fails in the presence of unknown xml elements cpu: Fail CPU comparison in the presence of unknown elements. src/conf/cpu_conf.c | 38 ++++++++++++++++++++ tests/cputest.c | 15 +++++--- tests/cputestdata/x86_64-bogus-attribute.xml | 2 ++ tests/cputestdata/x86_64-bogus-element.xml | 3 ++ 4 files changed, 54 insertions(+), 4 deletions(-) create mode 100644 tests/cputestdata/x86_64-bogus-attribute.xml create mode 100644 tests/cputestdata/x86_64-bogus-element.xml --=20 2.26.2

[libvirt PATCH] remote: slightly improve debugging of socket selection

[PATCH] qemu: fix concurrency crash bug in force snapshot revert
by Nikolay Shirokovskiy 16 Sep '20

16 Sep '20

This patch is just revert of [1]. Actually we should NOT pass QEMU_ASYNC_JOB_NONE as that patch suggests while we are in async job in order to acquire nested jobs correctly. The patch tries to fix issues introduced by another patch [2] where jobs are mistakenly cleared out in qemuProcessStop. Later patch [3] fixed the issue introduced by patch [2]. Now we need to revert [1] as well as we now still have same concurrency crash issues as [3] described but for the force revert.

[PATCH v3] cphp: remove deprecated cpu-add command(s)
by Igor Mammedov 15 Sep '20

15 Sep '20

These were deprecated since 4.0, remove both HMP and QMP variants. Users should use device_add command instead. To get list of possible CPUs and options, use 'info hotpluggable-cpus' HMP or query-hotpluggable-cpus QMP command.

device compatibility interface for live migration with assigned devices
by Yan Zhao 15 Sep '20

15 Sep '20

hi folks, we are defining a device migration compatibility interface that helps upper layer stack like openstack/ovirt/libvirt to check if two devices are live migration compatible. The "devices" here could be MDEVs, physical devices, or hybrid of the two. e.g. we could use it to check whether - a src MDEV can migrate to a target MDEV, - a src VF in SRIOV can migrate to a target VF in SRIOV, - a src MDEV can migration to a target VF in SRIOV. (e.g. SIOV/SRIOV backward compatibility case) The upper layer stack could use this interface as the last step to check if one device is able to migrate to another device before triggering a real live migration procedure. we are not sure if this interface is of value or help to you. please don't hesitate to drop your valuable comments. (1) interface definition The interface is defined in below way: __ userspace /\ \ / \write / read \ ________/__________ ___\|/_____________ | migration_version | | migration_version |-->check migration --------------------- --------------------- compatibility device A device B a device attribute named migration_version is defined under each device's sysfs node. e.g. (/sys/bus/pci/devices/0000\:00\:02.0/$mdev_UUID/migration_version). userspace tools read the migration_version as a string from the source device, and write it to the migration_version sysfs attribute in the target device. The userspace should treat ANY of below conditions as two devices not compatible: - any one of the two devices does not have a migration_version attribute - error when reading from migration_version attribute of one device - error when writing migration_version string of one device to migration_version attribute of the other device The string read from migration_version attribute is defined by device vendor driver and is completely opaque to the userspace. for a Intel vGPU, string format can be defined like "parent device PCI ID" + "version of gvt driver" + "mdev type" + "aggregator count". for an NVMe VF connecting to a remote storage. it could be "PCI ID" + "driver version" + "configured remote storage URL" for a QAT VF, it may be "PCI ID" + "driver version" + "supported encryption set". (to avoid namespace confliction from each vendor, we may prefix a driver name to each migration_version string. e.g. i915-v1-8086-591d-i915-GVTg_V5_8-1) (2) backgrounds The reason we hope the migration_version string is opaque to the userspace is that it is hard to generalize standard comparing fields and comparing methods for different devices from different vendors. Though userspace now could still do a simple string compare to check if two devices are compatible, and result should also be right, it's still too limited as it excludes the possible candidate whose migration_version string fails to be equal. e.g. an MDEV with mdev_type_1, aggregator count 3 is probably compatible with another MDEV with mdev_type_3, aggregator count 1, even their migration_version strings are not equal. (assumed mdev_type_3 is of 3 times equal resources of mdev_type_1). besides that, driver version + configured resources are all elements demanding to take into account. So, we hope leaving the freedom to vendor driver and let it make the final decision in a simple reading from source side and writing for test in the target side way. we then think the device compatibility issues for live migration with assigned devices can be divided into two steps: a. management tools filter out possible migration target devices. Tags could be created according to info from product specification. we think openstack/ovirt may have vendor proprietary components to create those customized tags for each product from each vendor. e.g. for Intel vGPU, with a vGPU(a MDEV device) in source side, the tags to search target vGPU are like: a tag for compatible parent PCI IDs, a tag for a range of gvt driver versions, a tag for a range of mdev type + aggregator count for NVMe VF, the tags to search target VF may be like: a tag for compatible PCI IDs, a tag for a range of driver versions, a tag for URL of configured remote storage. b. with the output from step a, openstack/ovirt/libvirt could use our proposed device migration compatibility interface to make sure the two devices are indeed live migration compatible before launching the real live migration process to start stream copying, src device stopping and target device resuming. It is supposed that this step would not bring any performance penalty as -in kernel it's just a simple string decoding and comparing -in openstack/ovirt, it could be done by extending current function check_can_live_migrate_destination, along side claiming target resources.[1] [1] https://specs.openstack.org/openstack/nova-specs/specs/stein/approved/libvi… Thanks Yan

[PATCH v2] cphp: remove deprecated cpu-add command(s)
by Igor Mammedov 14 Sep '20

14 Sep '20

theses were deprecated since 4.0, remove both HMP and QMP variants. Users should use device_add command instead. To get list of possible CPUs and options, use 'info hotpluggable-cpus' HMP or query-hotpluggable-cpus QMP command.

[PATCH 00/17] qemu: Fix startup of VM with SCSI hostdev with long user-provided alias
by Peter Krempa 14 Sep '20

14 Sep '20

Device alias was used to generate the backend nodename. This doesn't work well if somebody specifies a very long useralias since qemu limits nodename to 32 bytes.

[libvirt PATCH v2] esx: generator: fix free of elements in lists
by Pino Toscano 14 Sep '20

14 Sep '20

When a list is freed, we iterate through all the items, invoking the free function for each; the actual free function called for each element is the function of the actual type of each element, and thus the @_next pointer in the element struct has the same type as the element itself. Currently, the free function gets the parent of the current element type, and invoke its free function to continue freeing the list. However, in case the hierarchy of the classes has more than 1 level (i.e. Class <- SubClass <- SubSubClass), the invoked free function is only the parent class' one, and not the actual base class of the hierarchy. To fix that, change the generator to get the base class of a class, and invoking that instead. Also, avoid to set the @_next back, as it is not needed. Fixes commits 5cff36e39ae691fbd7c40597df1732eecf294150 and f76c6dde2e33233566e886d96e76b5fe0c102d9a.

[PATCH v2] network: Only check kernel added routes in virNetDevIPCheckIPv6Forwarding
by Ian Wienand 14 Sep '20

14 Sep '20

The original motivation for adding virNetDevIPCheckIPv6Forwarding (00d28a78b5d1f6eaf79f06ac59e31c568af9da37) was that networking routes would disappear when ipv6 forwarding was enabled for an interface. This is a fairly undocumented side-effect of the "accept_ra" sysctl for an interface. 1 means the interface will accept_ra's if not forwarding, 2 means always accept_RAs; but it is not explained that enabling forwarding when accept_ra==1 will also clear any kernel RA assigned routes, very likely breaking your networking. The check to warn about this currently uses netlink to go through all the routes and then look at the accept_ra status of the interfaces. However, it has been noticed that this problem does not affect systems where IPv6 RA configuration is handled in userspace, e.g. via tools such as NetworkManager. In this case, the error message from libvirt is spurious, and modifying the forwarding state will not affect the RA state or disable your networking. If you refer to the function rt6_purge_dflt_routers() in the kernel, we can see that the routes being purged are only those with the kernel's RTF_ADDRCONF flag set; that is, routes added by the kernel's RA handling. Why does it do this? I think this is a Linux implementation decision; it has always been like that and there are some comments suggesting that it is because a router should be statically configured, rather than accepting external configurations. The solution implemented here is to convert the existing check into a walk of /proc/net/ipv6_route and look for routes with this flag set. We then check the accept_ra status for the interface, and if enabling forwarding would break things raise an error. This should hopefully avoid "interactive" users, who are likely to be using NetworkManager and the like, having false warnings when enabling IPv6, but retain the error check for users relying on kernel-based IPv6 interface auto-configuration.

[libvirt PATCH v3 0/3] Add support for vDPA network devices
by Jonathon Jongsma 13 Sep '20

13 Sep '20

vDPA network devices allow high-performance networking in a virtual machine by providing a wire-speed data path. These devices require a vendor-specific host driver but the data path follows the virtio specification. The support for vDPA devices was recently added to qemu. This allows libvirt to support these devices. This patchset requires that the device is configured on the host with the appropriate vendor-specific driver. This will create a chardev on the host at e.g. /dev/vhost-vdpa-0. That chardev path can then be used to define a new interface with type='vdpa'. Changes in v3: - rebased to latest master - various small fixes per comments on last review - investigated hotplug -- I have a preliminary libvirt patch, but it doesn't appear that hotplug is fully supported in qemu yet. - qemu never closes the fd when the device is removed, so the device cannot be reassigned to a different domain. - I decided not to post the preliminary hotplug patch until I can get more clarity from qemu developers.

[PATCH v2 0/7] qemu: implementation of transient disk option
by Masayoshi Mizuma 13 Sep '20

13 Sep '20

This patchset tries to implement transient option for qcow2 and raw format disk. This uses the snapshot cleanup codes: https://www.redhat.com/archives/libvir-list/2020-August/msg00299.html It gets user available to set <transient/> to the domain xml file like as: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/guest.qcow2'/> <target dev='vda' bus='virtio'/> <transient/> </disk> Any changes which the Guest does to the disk is dropped when the Guest is shutdowned. There are some limitations for transient disk option so far: - Supported disk format is qcow2 and raw - blockdev capability is required for qemu - Following features are blocked with transient disk option - blockjobs - Migration - Disk hotplug Masayoshi Mizuma (7): qemuSnapshotDiskPrepareOne: Get available even if snapdisk is NULL qemu: Introduce functions to handle transient disk qemu: Add transient disk handler to start and stop the guest qemu: Transient option gets avaiable for qcow2 and raw format disk qemu: Block blockjobs when transient disk option is enabled qemu: Block migration when transient disk option is enabled qemu: Block disk hotplug when transient disk option is enabled src/qemu/qemu_domain.c | 7 ++ src/qemu/qemu_hotplug.c | 6 ++ src/qemu/qemu_migration.c | 22 ++++++ src/qemu/qemu_process.c | 8 +++ src/qemu/qemu_snapshot.c | 139 +++++++++++++++++++++++++++++++++++++- src/qemu/qemu_snapshot.h | 8 +++ src/qemu/qemu_validate.c | 9 ++- src/util/virstoragefile.h | 2 + 8 files changed, 196 insertions(+), 5 deletions(-) -- 2.27.0

[PATCH] network: Only check kernel added routes in virNetDevIPCheckIPv6Forwarding
by Ian Wienand 11 Sep '20

11 Sep '20

The original motivation for adding virNetDevIPCheckIPv6Forwarding (00d28a78b5d1f6eaf79f06ac59e31c568af9da37) was that networking routes would disappear when ipv6 forwarding was enabled for an interface. This is a fairly undocumented side-effect of the "accept_ra" sysctl for an interface. 1 means the interface will accept_ra's if not forwarding, 2 means always accept_RAs; but it is not explained that enabling forwarding when accept_ra==1 will also clear any kernel RA assigned routes, very likely breaking your networking. The check to warn about this currently uses netlink to go through all the routes and then look at the accept_ra status of the interfaces. However, it has been noticed that this problem does not affect systems where IPv6 RA configuration is handled in userspace, e.g. via tools such as NetworkManager. In this case, the error message from libvirt is spurious, and modifying the forwarding state will not affect the RA state or disable your networking. If you refer to the function rt6_purge_dflt_routers() in the kernel, we can see that the routes being purged are only those with the kernel's RTF_ADDRCONF flag set; that is, routes added by the kernel's RA handling. Why does it do this? I think this is a Linux implementation decision; it has always been like that and there are some comments suggesting that it is because a router should be statically configured, rather than accepting external configurations. The solution implemented here is to convert the existing check into a walk of /proc/net/ipv6_route and look for routes with this flag set. We then check the accept_ra status for the interface, and if enabling forwarding would break things raise an error. This should hopefully avoid "interactive" users, who are likely to be using NetworkManager and the like, having false warnings when enabling IPv6, but retain the error check for users relying on kernel-based IPv6 interface auto-configuration.

[PATCH v2] Fix linkage to libutil and libkvm on FreeBSD 11
by Daniel P. Berrangé 10 Sep '20

10 Sep '20

We are currently adding -lutil and -lkvm to the linker using the add_project_link_arguments method. On FreeBSD 11.4, this results in build errors because the args appear too early in the command line.

[libvirt PATCH] esx: generator: fix free of elements in lists
by Pino Toscano 10 Sep '20

10 Sep '20

When a list is freed, we iterate through all the items, invoking the free function for each; the actual free function called for each element is the function of the actual type of each element, and thus the @_next pointer in the element struct has the same type as the element itself. Currently, the free function gets the parent of the current element type, and invoke its free function to continue freeing the list. However, in case the hierarchy of the classes has more than 1 level (i.e. Class <- SubClass <- SubSubClass), the invoked free function is only the parent class' one, and not the actual base class of the hierarchy. To fix that, change the generator to get the ancestor of a class, and invoking that instead. Also, avoid to set the @_next back, as it is not needed. Fixes commits 5cff36e39ae691fbd7c40597df1732eecf294150 and f76c6dde2e33233566e886d96e76b5fe0c102d9a.

[PATCH] network: allow accept_ra == 0 when enabling ipv6 forwarding
by Ian Wienand 10 Sep '20

10 Sep '20

The checks modified here were added with 00d28a78b5d1f6eaf79f06ac59e31c568af9da37 to avoid losing routes on hosts. However, tools such as systemd-networking and NetworkManager manage RA's in userspace and thus IPv6 may be up and working on an interface even with accept_ra == 0. This modifies the check to only error if an interface's accept_ra is already set to "1"; as noted inline this seems to when it is likely that enabling forwarding may change the RA acceptance behaviour of the interface. I have noticed this because I am using the IPv6 NAT features enabled with 927acaedec7effbe67a154d8bfa0e67f7d08e6c7. I am using this on my laptop which switches between wired and wireless connections; both of which are configured in an unremarkable way by Fedora's NetworkManager and get configured for IPv6 via SLAAC and whatever NetworkManager magic it does.

[libvirt] [PATCH-for-4.2] hw/mips: Deprecate the r4k machine
by Philippe Mathieu-Daudé 10 Sep '20

10 Sep '20

The r4k machine was introduced in 2005 (6af0bf9c7) and its last logical change was in 2005 (9542611a6). After we can count 164 maintenance commits (QEMU API changes) with the exception of 1 fix in 2015 (memory leak, commit 3ad9fd5a). This machine was introduced as a proof of concept to run a MIPS CPU. 2 years later, the Malta machine was add (commit 5856de80) modeling a real platform. Note also this machine has no specification except 5 lines in the header of this file: * emulates a simple machine with ISA-like bus. * ISA IO space mapped to the 0x14000000 (PHYS) and * ISA memory at the 0x10000000 (PHYS, 16Mb in size). * All peripherial devices are attached to this "bus" with * the standard PC ISA addresses. It is time to deprecate this obsolete machine. Users are recommended to use the Malta board, which hardware is well documented.
