[libvirt] [PATCH] Fix misc bugs in virCommandPtr
by Daniel P. Berrange 15 Mar '11

15 Mar '11

The virCommandNewArgs() method would free the virCommandPtr if it failed to add the args. This meant errors reported in virCommandAddArgSet() were lost. Simply removing the check for errors from the constructor means they can be reported correctly later The virCommandAddEnvPassCommon() method failed to check for errors before reallocating the cmd->env array, causing a potential SEGV if cmd was NULL The virCommandAddArgSet() method needs to validate that at least 1 element in 'val's parameter is non-NULL, otherwise code like cmd = virCommandNew(binary) virCommandAddAtg(cmd, "foo") Would end up trying todo execve("foo"), if binary was NULL. --- src/util/command.c | 13 ++++++++----- 1 files changed, 8 insertions(+), 5 deletions(-) diff --git a/src/util/command.c b/src/util/command.c index ff2bd46..22f350b 100644 --- a/src/util/command.c +++ b/src/util/command.c @@ -109,11 +109,6 @@ virCommandNewArgs(const char *const*args) virCommandAddArgSet(cmd, args); - if (cmd->has_error) { - virCommandFree(cmd); - return NULL; - } - return cmd; } @@ -362,6 +357,9 @@ virCommandAddEnvPass(virCommandPtr cmd, const char *name) void virCommandAddEnvPassCommon(virCommandPtr cmd) { + if (!cmd || cmd->has_error) + return; + /* Attempt to Pre-allocate; allocation failure will be detected * later during virCommandAdd*. */ ignore_value(VIR_RESIZE_N(cmd->env, cmd->maxenv, cmd->nenv, 9)); @@ -478,6 +476,11 @@ virCommandAddArgSet(virCommandPtr cmd, const char *const*vals) if (!cmd || cmd->has_error) return; + if (vals[0] == NULL) { + cmd->has_error = EINVAL; + return; + } + while (vals[narg] != NULL) narg++; -- 1.7.4

[libvirt] [PATCH 0/4] white space handling in libvirt-guest.init script
by Philipp Hahn 15 Mar '11

15 Mar '11

libvirt-guest doesn't correctly handle the case, that the domain name contains blanks, when it parses the output of "virsh dominfo | grep Name". While investigating this this bug, I took the opportunity to also fix several other potential quoting problems in libvirt-guest.init. Those further changes might be controversial, since most variables will never contain characters from IFS, but since I encountered several problems with scripts not quoting variables in the past, I personally tend to quote almost every variable which must contains exactly one single value. The last patch is not for application, but since I had to do it anyway, I'll include it for others for inspiration. So #1 is the most important, #2 and #3 depends on your preferred style, and #4 is just FYI only.

[libvirt] [PATCH v2] Allow to dynamically set the size of the debug buffer
by Daniel Veillard 15 Mar '11

15 Mar '11

Changes in v2: - fixes based on comment received (except using size_t for the reason provided) - avoid a deadlock in case of error allocating the buffer - make more clear that 64 kB is the default and any value <= 0 deactivate the buffer This is the part allowing to dynamically resize the debug log buffer from it's default 64kB size. The buffer is now dynamically allocated. It adds a new API virLogSetBufferSize() which resizes the buffer (possibly dynamically but in that case the existing content is lost - the complexity wasn't looking like worth it). If passed a zero or less size, the buffer is deallocated and we do the small optimization of not formatting messages which are not output anymore. On the daemon side, it just adds a new option log_buffer_size to libvirtd.conf and call virLogSetBufferSize() if needed. Seems to work fine, I tried to keep the code as simple as needed, this allowed me to find out that on a quiet daemon startup we emit half a megabyte of debug log ! Daniel

[libvirt] [PATCH] virsh: optimize creation of default connection
by Eric Blake 14 Mar '11

14 Mar '11

Ramon de Carvalho Valle reported a problem with: virsh connect qemu:///system as a non-root user. The real root problem appears to be a regression in libvirtd being auto-started on the default qemu:///session URI; however, the symptom points to an independent flaw in virsh - we shouldn't be wasting efforts on making a connection if we aren't going to be using that connection. Fixing virsh avoids Ramon's issue, while I work in the meantime to fix the real libvirtd regression. This patch looks big, but that's because 'gcc -Wmissing-field-initializers' gets triggered by './autobuild.sh --enable-compile-warnings=error', so I had to add 0 initialization to everyone (rather than my preference of just adding the non-zero flags to virshCmds and to cmdConnect). Meanwhile, if you use 'virsh -c URI', the connection must succeed; this patch _only_ optimizes the default connection to be deferred to a later point where we know if a particular command to be run needs a connection. * tools/virsh.c (VSH_CMD_FLAG_NOCONNECT): New flag. (vshCmdDef): Add new flags field. (vshCommandRun): Honor new flag. (domManagementCmds, domMonitoringCmds, storagePoolCmds) (storageVolCmds, networkCmds, nodedevCmds, ifaceCmds) (nwfilterCmds, secretCmds, virshCmds, snapshotCmds) (hostAndHypervisorCmds): Populate new field.

[libvirt] [PATCH v2] domain.rng vs. formatdomain.html#elementsUSB
by Philipp Hahn 14 Mar '11

14 Mar '11

The Relax-NG schema for domains regarding <hostdev> doesn't match what's implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The implementation only requires @type, but the schema currently either required none or all three attributes (@mode, @type, and @managed) to be defined together, because they are declared in the same <optional)-section. (@managed is currently even undocumented on <http://libvirt.org/formatdomain.html#elementsUSB>). Thus the following minimal <hostdev>-example fails to validate: <domain type='test'> <name>N</name> <memory>4096</memory> <bootloader>/bin/false</bootloader> <os> <type arch='x86_64' machine='xenpv'>linux</type> </os> <devices> <hostdev type='pci'> <source> <address bus='0x06' slot='0x00' function='0x0'/> </source> </hostdev> </devices> </domain> The schema is changed to match the current implementation: 1. @mode is optional (which defaults to 'subsystem') 2. @type is required 3. @managed is optional (which defaults to 'no') Signed-off-by: Philipp Hahn <hahn(a)univention.de> --- docs/schemas/domain.rng | 14 ++++++++------ 1 files changed, 8 insertions(+), 6 deletions(-) diff --git a/docs/schemas/domain.rng b/docs/schemas/domain.rng index 8b215f3..21c4380 100644 --- a/docs/schemas/domain.rng +++ b/docs/schemas/domain.rng @@ -1731,12 +1731,14 @@ <value>capabilities</value> </choice> </attribute> - <attribute name="type"> - <choice> - <value>usb</value> - <value>pci</value> - </choice> - </attribute> + </optional> + <attribute name="type"> + <choice> + <value>usb</value> + <value>pci</value> + </choice> + </attribute> + <optional> <attribute name="managed"> <choice> <value>yes</value> -- 1.7.1

[libvirt] [PATCH] audit: eliminate potential null pointer deref when auditing macvtap devices
by Laine Stump 14 Mar '11

14 Mar '11

The newly added call to qemuAuditNetDevice in qemuPhysIfaceConnect was assuming that res_ifname (the name of the macvtap device) was always valid, but this isn't the case. If openMacvtapTap fails, it always returns NULL, which would result in a segv. Since the audit log only needs a record of devices that are actually sent to qemu, and a failure to open the macvtap device means that no device will be sent to qemu, we can solve this problem by only doing the audit if openMacvtapTap is successful (in which case res_ifname is guaranteed valid). --- src/qemu/qemu_command.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 8ca656a..72f55d0 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -128,8 +128,8 @@ qemuPhysIfaceConnect(virDomainDefPtr def, net->data.direct.mode, vnet_hdr, def->uuid, &net->data.direct.virtPortProfile, &res_ifname, vmop); - qemuAuditNetDevice(def, net, res_ifname, rc >= 0); if (rc >= 0) { + qemuAuditNetDevice(def, net, res_ifname, true); VIR_FREE(net->ifname); net->ifname = res_ifname; } -- 1.7.3.4

[libvirt] [PATCH] python: Use hardcoded python path in libvirt.py
by Jiri Denemark 14 Mar '11

This partially reverts (and fixes that part in a different way) commit e4384459c93e3e786aa483c7f077d1d22148f689, which replaced all examples or scripts used during build to generate other files. However, python bindings module is compiled and linked against a specific python discovered or explicitly provided in configure phase. Thus libvirt.py which is generated and installed into the system we should use the same python binary for which the module has been built. The hunk in Makefile.am replaces $(srcdir) with $(PYTHON), which might seem wrong but it is not. generator.py didn't use any of its command line arguments so passing $(srcdir) to it was redundant. --- python/Makefile.am | 2 +- python/generator.py | 7 ++++++- python/libvirt-override.py | 5 ----- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/python/Makefile.am b/python/Makefile.am index eda2866..432ad70 100644 --- a/python/Makefile.am +++ b/python/Makefile.am @@ -53,7 +53,7 @@ GENERATED= libvirt-export.c \ libvirt.py generated.stamp: $(srcdir)/$(GENERATE) $(API_DESC) - $(PYTHON) $(srcdir)/$(GENERATE) $(srcdir) + $(PYTHON) $(srcdir)/$(GENERATE) $(PYTHON) touch $@ $(GENERATED): generated.stamp diff --git a/python/generator.py b/python/generator.py index 6f4bb40..4fa4f65 100755 --- a/python/generator.py +++ b/python/generator.py @@ -14,6 +14,11 @@ import re if __name__ == "__main__": # launched as a script srcPref = os.path.dirname(sys.argv[0]) + if len(sys.argv) > 1: + python = sys.argv[1] + else: + print "Python binary not specified" + sys.exit(1) else: # imported srcPref = os.path.dirname(__file__) @@ -1012,7 +1017,7 @@ def buildWrappers(): classes = open("libvirt.py", "w") extra = open(os.path.join(srcPref,"libvirt-override.py"), "r") - classes.write("#!/usr/bin/env python\n") + classes.write("#!

[libvirt] [PATCH] network driver: don't send default route to clients on isolated networks
by Laine Stump 14 Mar '11

14 Mar '11

Normally dnsmasq will send a default route (the address of the host in the network definition) to any client requesting an address via DHCP. On an isolated network this makes no sense, as we have iptables to prevent any traffic going out via that interface, so anything sent that way would be dropped anyway. This extra/unusable default route becomes problematic if you have setup a guest with multiple network interfaces, with one connected to an isolated network and another that provides connectivity to the outside (example - one interface directly connecting to a physical interface via macvtap, with a second connected to an isolated network so that the host and guest can communicate (macvtap doesn't support guest<->host communication without an external switch that supports vepa, or reflecting all traffic back)). In this case, if the guest chooses the default route of the isolated network, the guest will not be able to get network traffic beyond the host. To prevent dnsmasq from sending a default route, you can tell it to send 0 bytes of data for the default route option (option number 3) with --dhcp-option=3 (normally the data to send for the option would follow the option number; no extra data means "don't send this option"). I have checked on RHEL5 (a good representative of the oldest supported libvirt platforms) and its version of dnsmasq (2.45) does support --dhcp-option, so this shouldn't create any compatibility problems. --- src/network/bridge_driver.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index ca2ae8d..6a02df1 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -490,6 +490,13 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, "--except-interface", "lo", NULL); + /* If this is an isolated network, set the default route option + * (3) to be empty to avoid setting a default route that's + * guaranteed to not work. + */ + if (network->def->forwardType == VIR_NETWORK_FORWARD_NONE) + virCommandAddArg(cmd, "--dhcp-option=3"); + /* * --interface does not actually work with dnsmasq < 2.47, * due to DAD for ipv6 addresses on the interface. -- 1.7.3.4

[libvirt] [v3] qemu: Support vram for video of qxl type
by Osier Yang 14 Mar '11

14 Mar '11

For qemu names the primary vga as "qxl-vga": 1) if vram is specified for 2nd qxl device: -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,vram_size=$SIZE,... 2) if vram is not specified for 2nd qxl device, (use the default set by global): -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,... For qemu names all qxl devices as "qxl": 1) if vram is specified for 2nd qxl device: -vga qxl -global qxl.vram_size=$SIZE \ -device qxl,id=video1,vram_size=$SIZE ... 2) if vram is not specified for 2nd qxl device: -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,... "-global" is the only way to define vram_size for the primary qxl device, regardless of how qemu names it, (It's not good a good way, as original idea of "-global" is to set a global default for a driver property, but to specify vram for first qxl device, we have to use it). For other qxl devices, as they are represented by "-device", could specify it directly and seperately for each, and it overrides the default set by "-global" if specified. v1 - v2: * modify "virDomainVideoDefaultRAM" so that it returns 16M as the default vram_size for qxl device. * vram_size * 1024 (qemu accepts bytes for vram_size). * apply default vram_size for qxl device for which vram_size is not specified. * modify "graphics-spice" tests (more sensiable vram_size) * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr, to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr). v2 - v3: * Modify default video memory size for qxl device from 16M to 24M * Update codes to be consistent with changes on qemu_capabilities.* --- src/conf/domain_conf.c | 4 ++ src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 18 ++++++++++ tests/qemuhelptest.c | 1 + .../qemuxml2argv-graphics-spice-qxl-vga.args | 7 ++++ .../qemuxml2argv-graphics-spice-qxl-vga.xml | 36 ++++++++++++++++++++ .../qemuxml2argv-graphics-spice.args | 4 +- .../qemuxml2argv-graphics-spice.xml | 4 +- tests/qemuxml2argvtest.c | 4 ++ tests/qemuxml2xmltest.c | 1 + 11 files changed, 78 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-qxl-vga.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-qxl-vga.xml diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index c8350c6..16e1291 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -4167,6 +4167,10 @@ virDomainVideoDefaultRAM(virDomainDefPtr def, /* Original Xen PVFB hardcoded to 4 MB */ return 4 * 1024; + case VIR_DOMAIN_VIDEO_TYPE_QXL: + /* QEMU use 64M as the minimal video video memory for qxl device */ + return 64 * 1024; + default: return 0; } diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 477924d..d8aa9cd 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -1122,6 +1122,8 @@ qemuCapsParseDeviceStr(const char *str, virBitmapPtr flags) } if (strstr(str, "virtio-net-pci.tx=")) qemuCapsSet(flags, QEMU_CAPS_VIRTIO_TX_ALG); + if (strstr(str, "name \"qxl-vga\"")) + qemuCapsSet(flags, QEMU_CAPS_DEVICE_QXL_VGA); return 0; } diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index a61b088..68c5958 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -94,6 +94,7 @@ enum qemuCapsFlags { QEMU_CAPS_CHARDEV_SPICEVMC = 56, /* newer -chardev spicevmc */ QEMU_CAPS_DEVICE_SPICEVMC = 57, /* older -device spicevmc*/ QEMU_CAPS_VIRTIO_TX_ALG = 58, /* -device virtio-net-pci,tx=string */ + QEMU_CAPS_DEVICE_QXL_VGA = 59, /* Is the primary and vga campatible qxl device named qxl-vga? */ QEMU_CAPS_LAST, /* this must always be the last item */ }; diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index fa60abe..198a4e2 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1931,6 +1931,12 @@ qemuBuildVideoDevStr(virDomainVideoDefPtr video, virBufferVSprintf(&buf, "%s", model); virBufferVSprintf(&buf, ",id=%s", video->info.alias); + + if (video->type == VIR_DOMAIN_VIDEO_TYPE_QXL) { + /* QEMU accepts bytes for vram_size. */ + virBufferVSprintf(&buf, ",vram_size=%u", video->vram * 1024); + } + if (qemuBuildDeviceAddressStr(&buf, &video->info, qemuCaps) < 0) goto error; @@ -4033,6 +4039,18 @@ qemuBuildCommandLine(virConnectPtr conn, } virCommandAddArgList(cmd, "-vga", vgastr, NULL); + + if (def->videos[0]->type == VIR_DOMAIN_VIDEO_TYPE_QXL) { + if (def->videos[0]->vram && + qemuCapsGet(qemuCaps, QEMU_CAPS_DEVICE)) { + if (qemuCapsGet(qemuCaps, QEMU_CAPS_DEVICE_QXL_VGA)) + virCommandAddArgFormat(cmd, "-global qxl-vga.vram_size=%u", + def->videos[0]->vram * 1024); + else + virCommandAddArgFormat(cmd, "-global qxl.vram_size=%u", + def->videos[0]->vram * 1024); + } + } } } else { diff --git a/tests/qemuhelptest.c b/tests/qemuhelptest.c index 335364f..c86c578 100644 --- a/tests/qemuhelptest.c +++ b/tests/qemuhelptest.c @@ -489,6 +489,7 @@ mymain(int argc, char **argv) QEMU_CAPS_DRIVE_AIO, QEMU_CAPS_CCID_PASSTHRU, QEMU_CAPS_CHARDEV_SPICEVMC, + QEMU_CAPS_DEVICE_QXL_VGA, QEMU_CAPS_VIRTIO_TX_ALG); return ret == 0 ?
