[libvirt] [PATCH v3 00/19] Integrate usage of glib into libvirt

by Daniel P. Berrangé

This is a followup to a previous patch series: v0: https://www.redhat.com/archives/libvir-list/2019-August/msg01374.html v1: https://www.redhat.com/archives/libvir-list/2019-September/msg01331.html v2: https://www.redhat.com/archives/libvir-list/2019-October/msg00271.html The focus in this glib series is - Wire up pieces to facilitate interoperability around memory allocation/cleanup. - Deprecate & document existing libvirt APIs that are targetted for removal/conversion. - Illustrate some conversions and/or usage of new APIs. - Convert code that allows us to eliminate more gnulib modules There's obviously alot of conversion work that could be done, especially around memory allocation, auto cleanup and virObject stuff. I'm not intending to do that myself in the short term, as my immediate focus is on eliminating gnulib modules. Once this series is merged though, anyone is able to take on conversion jobs, so this allows the work to be spread out across the contributors. changed in v2: - First patch gets an addition to .travis.yml to add glib2 on macOS - First patch blacklists -Wbad-function-cast warning flag - Second patch updates many makefiles to refer to $(GLIB_LIBS) to fix build on platforms with stricter linkers (Ubuntu) - virIdentity conversion uses _ consistently in methods - GOptionContext conversions are dropped Daniel P. Berrangé (19): build: probe for glib-2 library in configure build: link to glib library util: use glib memory allocation functions util: use glib string allocation/formatting functions util: convert virSystemdActivation to use VIR_DEFINE_AUTOPTR_FUNC util: rewrite auto cleanup macros to use glib's equivalent src: add support for g_autoptr with virObject instances conf: convert virSecretObj APIs to use autofree util: use glib base64 encoding/decoding APIs util: convert virIdentity implementation and test suite to g_autoptr access: convert polkit driver to auto free memory admin: convert admin server code to use auto free macros rpc: convert methods using virIdentityPtr to auto free macros remote: convert methods using virIdentityPtr to auto free macros util: convert virIdentity class to use GObject libxl: convert over to use GRegex for regular expressions conf: convert over to use GRegex for regular expressions util: replace strerror/strerror_r with g_strerror build: remove use of usleep gnulib module in favour of g_usleep .travis.yml | 1 + bootstrap.conf | 8 -- build-aux/syntax-check.mk | 2 +- configure.ac | 7 +- docs/hacking.html.in | 144 ++++++++------------ libvirt.spec.in | 1 + m4/virt-compile-warnings.m4 | 23 ++++ m4/virt-glib.m4 | 36 +++++ mingw-libvirt.spec.in | 2 + src/Makefile.am | 3 + src/access/Makefile.inc.am | 4 +- src/access/viraccessdriverpolkit.c | 38 ++---- src/admin/admin_server.c | 204 ++++++++++++---------------- src/bhyve/Makefile.inc.am | 1 + src/conf/capabilities.h | 3 + src/conf/domain_capabilities.h | 3 + src/conf/domain_conf.h | 3 + src/conf/domain_event.c | 25 ++-- src/conf/snapshot_conf.h | 3 + src/conf/storage_capabilities.h | 3 + src/conf/virsecretobj.c | 68 +++------- src/datatypes.h | 15 ++ src/hyperv/hyperv_driver.c | 2 +- src/hyperv/hyperv_wmi.c | 4 +- src/interface/Makefile.inc.am | 1 + src/internal.h | 1 + src/libvirt_private.syms | 1 - src/libxl/Makefile.inc.am | 1 + src/libxl/libxl_capabilities.c | 42 +++--- src/libxl/libxl_conf.c | 3 +- src/libxl/libxl_conf.h | 2 + src/locking/Makefile.inc.am | 9 +- src/locking/lock_daemon.c | 2 +- src/locking/lock_driver_sanlock.c | 2 +- src/logging/Makefile.inc.am | 1 + src/lxc/Makefile.inc.am | 4 + src/lxc/lxc_controller.c | 2 +- src/lxc/lxc_driver.c | 2 +- src/lxc/lxc_process.c | 2 +- src/network/Makefile.inc.am | 2 + src/network/bridge_driver.c | 2 +- src/node_device/Makefile.inc.am | 5 +- src/nwfilter/Makefile.inc.am | 1 + src/nwfilter/nwfilter_dhcpsnoop.c | 4 +- src/nwfilter/nwfilter_learnipaddr.c | 2 +- src/qemu/Makefile.inc.am | 1 + src/qemu/qemu_agent.c | 6 +- src/qemu/qemu_blockjob.h | 1 + src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_command.c | 5 +- src/qemu/qemu_conf.h | 3 + src/qemu/qemu_domain.c | 8 +- src/qemu/qemu_monitor_json.c | 2 +- src/qemu/qemu_process.c | 6 +- src/qemu/qemu_tpm.c | 2 +- src/remote/Makefile.inc.am | 2 + src/remote/remote_daemon.c | 3 +- src/remote/remote_daemon_dispatch.c | 35 ++--- src/rpc/virnetserverclient.c | 57 ++++---- src/rpc/virnetserverprogram.c | 13 +- src/rpc/virnetsocket.c | 2 +- src/secret/Makefile.inc.am | 1 + src/secret/secret_driver.c | 1 - src/security/Makefile.inc.am | 1 + src/security/security_manager.c | 2 +- src/storage/Makefile.inc.am | 16 +++ src/storage/storage_backend_rbd.c | 4 +- src/storage/storage_util.c | 4 +- src/util/viralloc.c | 29 +--- src/util/viralloc.h | 14 +- src/util/virautoclean.h | 38 +++--- src/util/vircgroup.c | 2 +- src/util/virerror.c | 9 +- src/util/virerror.h | 1 + src/util/virfile.c | 2 +- src/util/virhostdev.h | 3 + src/util/viridentity.c | 92 +++++++------ src/util/viridentity.h | 7 +- src/util/virmdev.h | 3 + src/util/virnetdev.c | 2 +- src/util/virnetdevip.c | 2 +- src/util/virnetdevmacvlan.c | 2 +- src/util/virnetdevvportprofile.c | 2 +- src/util/virobject.h | 4 + src/util/virpci.c | 8 +- src/util/virpci.h | 3 + src/util/virprocess.c | 4 +- src/util/virresctrl.h | 4 + src/util/virscsi.h | 3 + src/util/virscsivhost.h | 3 + src/util/virstoragefile.h | 2 + src/util/virstring.c | 49 +++---- src/util/virstring.h | 10 +- src/util/virsystemd.c | 10 +- src/util/virsystemd.h | 5 +- src/util/virtime.c | 2 +- src/util/virusb.h | 3 + src/vbox/Makefile.inc.am | 1 + src/vbox/vbox_common.c | 2 +- src/vz/Makefile.inc.am | 1 + tests/Makefile.am | 7 +- tests/commandtest.c | 16 +-- tests/eventtest.c | 4 +- tests/fdstreamtest.c | 4 +- tests/qemumonitortestutils.c | 2 +- tests/seclabeltest.c | 4 +- tests/testutils.c | 6 +- tests/virhostcputest.c | 4 +- tests/viridentitytest.c | 45 +++--- tests/virnetserverclienttest.c | 3 +- tests/virsystemdtest.c | 2 +- tests/virtestmock.c | 4 +- tools/Makefile.am | 4 + tools/virsh-domain.c | 2 +- tools/virsh-secret.c | 17 +-- 115 files changed, 667 insertions(+), 650 deletions(-) create mode 100644 m4/virt-glib.m4 -- 2.21.0

[libvirt] [PATCH v2] util: Block SIGPIPE until execve in child process

by Wang Yechao

Libvirtd has set SIGPIPE to ignored, and virFork resets all signal handlers to the defaults. But child process may write logs to stderr/stdout, that may generate SIGPIPE if journald has stopped. So block SIGPIPE in virFork, and unblock it before execve.

[libvirt] Question about migration confirm phase

by Jim Fehlig

I've been investigating a lockd lock ordering bug in a migration error handling path in the libxl driver. In the perform phase, the src calls virDomainLockProcessPause to release the lock before sending the VM to dst. In this case the send fails for other reasons and an attempt is made to reacquire the lock with virDomainLockProcessResume. But that fails since the dst has not finished cleaning up the failed VM and releasing the lock it acquired when starting to receive the VM. My immediate reaction was "why not reacquire the lock in the confirm phase", but then I saw my older comment a few lines later in the perform phase code /* * Confirm phase will not be executed if perform fails. End the * job started in begin phase. */ Is that just a bug in the implementation, or is it intended to skip the confirm phase if perform fails? Regards, Jim

If so, then it's not really a <disk>, and so using the existing vhost-scsi support in <hostdev> is probably better. <hostdev> could possible be used for vhost-user-blk as well Can you provide some examples of full qemu command lines using vhost-user-blk and vhost-user-scsi? Just linking to examples else where is fine, but I'm wondering if there's more context Internally we already have an abstraction for vhost-scsi: <hostdev mode='subsystem' type='scsi_host'> <source protocol='vhost' wwpn='XXX'/> </hostdev> The obvious extension would be <hostdev mode='subsystem' type='scsi_host'> <source protocol='vhostuser' type='unix' path='/path/to/vhost-user-scsi.sock' mode='client'/> </hostdev> Internally implementing this will be weird. The <source> parameters are only dictated by the hostdev type= field, but in this case they would be dictated by the <source protocol=> field, and we would want to reuse the internal chardev abstraction. vhost-user-blk could be implemented similarly, but with type='storage' which is the way we pass through block devices to LXC guests, but it isn't currently supported in the qemu driver. I dunno. Maybe Michal or danpb can provide guidance > Conclusion: > 1. Add new type(vhostuser) for disk label; > 2.

But then its not really a <controller> in libvirt's sense because we can't attach emulated devices to it, so it's more a fit for the existing <hostdev> vhost-user support. Unfortunately it's not really a clean fit anywhere, there will have to be some kind of compromise. And I'm not sure if <disk> or <hostdev> is right for vhost-user-blk, but hopefully others have more clear opinions.

[libvirt] [PATCH v2 0/3] unplug timeout changes for PPC64

by Daniel Henrique Barboza

This is a redesign of the previous patch series [1]. After the reviews of the first version, I ended up discarding the idea of a qemu user configuration for the unplug timeout value. Instead, this patch series now handles the problematic case of PPC64 guests with an exclusive PPC64 only timeout value of 10 seconds. Patch 3 now changes how the 'unplug timeout' message is reported, using VIR_ERR_OPERATION_TIMEOUT instead of VIR_ERR_OPERATION_FAILED and making it clearer that the timeout does not equal to unplug failed.
