[libvirt] [PATCH] qemu_driver: don't leak a virDomainDeviceDef buffer
by Jim Meyering 19 Jan '10

19 Jan '10

At first I was going to call virDomainDeviceDefFree only "if (dev)", but saw that it handles a NULL "dev" just fine, so it's better to skip the test altogether, just as we do for many other free-like functions. >From ea8511d709492f5cdc152a1eaccbccd05f036648 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 16:55:36 +0100 Subject: [PATCH] qemu_driver: don't leak a virDomainDeviceDef buffer * src/qemu/qemu_driver.c (qemudDomainAttachDevice): Don't leak "dev". --- src/qemu/qemu_driver.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 365921f..1aa8af6 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6062,11 +6062,11 @@ cleanup: if (cgroup) virCgroupFree(&cgroup); - if (ret < 0 && dev != NULL) { + if (ret < 0 && dev != NULL) if (qemuDomainSetDeviceOwnership(dom->conn, driver, dev, 1) < 0) VIR_WARN0("Fail to restore disk device ownership"); - virDomainDeviceDefFree(dev); - } + virDomainDeviceDefFree(dev); + if (vm) virDomainObjUnlock(vm); qemuDriverUnlock(driver); -- 1.6.6.638.g2bc54

[libvirt] 0.7.5 errors in configure script

Hi, I am using Ubuntu 9.10 and downloaded and extracted libvirt.0.7.5. I have issued: ./configure --prefix=$HOME/usr --without-xen but I get: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt Below is a snippet of the final configure output: checking for showmount... no checking for pvcreate... no checking for vgcreate... no checking for lvcreate... no checking for pvremove... no checking for vgremove... no checking for lvremove... no checking for vgchange... no checking for vgscan... no checking for pvs... no checking for vgs... no checking for lvs... no checking for iscsiadm... no checking for DEVMAPPER... no checking libdevmapper.h usability... no checking libdevmapper.h presence... no checking for libdevmapper.h... no checking for dm_task_run in -ldevmapper... no configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt /dev/mapper exists on the system.

[libvirt] [PATCH 00/34] Add device addressing and disk controller support
by Daniel P. Berrange 18 Jan '10

18 Jan '10

This series is a merge of two previous series I posted http://www.redhat.com/archives/libvir-list/2009-December/msg00232.html http://www.redhat.com/archives/libvir-list/2009-December/msg00392.html It accomplishes quite a lot of things, having major impact on the QEMU driver, hopefully all in a postive way :-) In particular it does * Add standard XML syntax for addressing of PCI devices, and disk drives * Add support for disk controllers as a managed device in XML * Add support for disk controller hotplug/unplug * Convert everything over to use QEMU's -device flag where available * Add PCI addressing when using -device * Introduce a way to give every device a unique 'alias' name in the XML format I can't promise it works perfectly, but i've done quite alot of positive testing with it now & believe all the back comptability stuff is working right.

[libvirt] [PATCH] storage_backend_fs.c: do not ignore probe failure
by Jim Meyering 18 Jan '10

18 Jan '10

When virStorageBackendProbeTarget fails, it returns -1 or -2. The two uses below obviously intended to handle those cases differently, but due to a wrong comparison, they always treated a "real" (e.g., open) failure (-1) just like an ignorable "wrong file type" failure (-2). FYI, coverity reported that the "goto cleanup" statement was unreachable, which was true in each case, but hardly the real problem. >From c9ba79daf124afbab351741192bbaf7110a199dd Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:34:53 +0100 Subject: [PATCH] storage_backend_fs.c: do not ignore probe failure * src/storage/storage_backend_fs.c (virStorageBackendFileSystemRefresh): Correct two error-handling bugs.

[libvirt] [PATCH] secret_driver.c: remove dead cleanup code
by Jim Meyering 18 Jan '10

18 Jan '10

Here's another example of appropriate use of assert. The while loop removed below is currently guaranteed never to be executed, since "list" is always NULL at that point. However, you can argue that simply removing the loop is a little risky: what if someone changes things to "goto cleanup" before "list" reaches the final NULL? That's why I added the assertion: to catch the potential (albeit unlikely) future coding error. It would be a shame to include "real" run-time code to detect a situation like that that will probably never arise. And if you do, technically you'd have to document that the function would return some sort of error code if a developer changes its guts in a way that violates this invariant. That would be nonsensical. >From 6baa2b0b8f9963fa60ff0946afcefd57586e2720 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:46:57 +0100 Subject: [PATCH] secret_driver.c: remove dead cleanup code * src/secret/secret_driver.c (loadSecrets): Remove dead code after "cleanup:".

[libvirt] [PATCH] Use closest CPU model when decoding from CPUID
by Jiri Denemark 18 Jan '10

18 Jan '10

Current implementation of x86Decode() used for CPUID -> model+features translation does not always select the closest CPU model. When walking through all models from cpu_map.xml the function considers a new candidate as a better choice than a previously selected candidate only if the new one is a superset of the old one. In case the new candidate is closer to host CPU but lacks some feature comparing to the old candidate, the function does not choose well. This patch changes the algorithm so that the closest model is always selected. That is, the model which requires the lowest number of additional features to describe host CPU.

[libvirt] [PATCH 0/4] A bit of configure clear-up
by Diego Elio Pettenò 18 Jan '10

18 Jan '10

Since on the whole it seems like the configure could see some cleanup, as it seem to use lots of older constructs and repeated code, I tried doing some basic cleaning. My changes also require autoconf-2.63… it could be something older as well, but 2.63 is new enough I'd say. If nobody has reasons for 2.59 compatibility to stick around, it would probably improve a lot. HTH! -- Diego

[libvirt] [PATCH] qemu: Use log output for pty assignment if 'info chardev' is unavailable
by Matthias Bolte 18 Jan '10

18 Jan '10

qemudFindCharDevicePTYsMonitor reports an error if 'info chardev' didn't provide information for a requested device, even if the log output parsing had found the pty path for that device. This makes pty assignment fail for older QEMU/KVM versions. For example KVM 72 on Debian doesn't support 'info chardev', so qemuMonitorTextGetPtyPaths cannot parse any useful information and the hash for device-id-to-pty-path mapping stays empty. Make qemudFindCharDevicePTYsMonitor report an error only if the log output parsing and the 'info chardev' parsing failed to provide the pty path. --- src/qemu/qemu_driver.c | 14 +++++++++++--- 1 files changed, 11 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index d13119f..783d9fc 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1428,9 +1428,17 @@ qemudFindCharDevicePTYsMonitor(virConnectPtr conn, \ const char *path = (const char *) virHashLookup(paths, id); \ if (path == NULL) { \ - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR,\ - _("no assigned pty for device %s"), id); \ - return -1; \ + if (chr->data.file.path == NULL) { \ + /* neither the log output nor 'info chardev' had a */ \ + /* pty path for this chardev, report an error */ \ + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, \ + _("no assigned pty for device %s"), id); \ + return -1; \ + } else { \ + /* 'info chardev' had no pty path for this chardev, */\ + /* but the log output had, so we're fine */ \ + continue; \ + } \ } \ \ VIR_FREE(chr->data.file.path); \ -- 1.6.3.3
