by Cole Robinson 02 May '12

02 May '12

Okay, I screwed up the tarball for the first stable release, due to not building it from a fresh checkout :/ No changes for this one except a version bump and dist rebuild. This release can be downloaded at: http://libvirt.org/sources/libvirt-0.9.11.2.tar.gz Thanks, Cole

[libvirt] [PATCH] Use XDG Base Directories instead of storing in home directory
by William Jon McCann 02 May '12

02 May '12

As defined in: http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html This offers a number of advantages: * Allows sharing a home directory between different machines, or sessions (eg. using NFS) * Cleanly separates cache, runtime (eg. sockets), or app data from user settings * Supports performing smart or selective migration of settings between different OS versions * Supports reseting settings without breaking things * Makes it possible to clear cache data to make room when the disk is filling up * Allows us to write a robust and efficient backup solution * Allows an admin flexibility to change where data and settings are stored * Dramatically reduces the complexity and incoherence of the system for administrators --- AUTHORS | 1 + daemon/libvirtd-config.c | 10 +-- daemon/libvirtd.c | 140 +++++++++++++++++++++++++++++++++------- daemon/libvirtd.pod.in | 2 +- docs/auth.html.in | 2 +- docs/uri.html.in | 2 +- src/libvirt.c | 4 +- src/libvirt_private.syms | 4 ++ src/network/bridge_driver.c | 8 ++- src/nwfilter/nwfilter_driver.c | 11 +--- src/qemu/qemu_driver.c | 32 +++++---- src/remote/remote_driver.c | 4 +- src/remote/remote_driver.h | 2 +- src/secret/secret_driver.c | 11 +--- src/storage/storage_driver.c | 13 +--- src/uml/uml_driver.c | 10 +-- src/util/util.c | 67 +++++++++++++++++++ src/util/util.h | 4 ++ src/util/virauth.c | 4 +- tools/virsh.c | 6 +- 20 files changed, 248 insertions(+), 89 deletions(-) diff --git a/AUTHORS b/AUTHORS index 06b830a..668eca1 100644 --- a/AUTHORS +++ b/AUTHORS @@ -234,6 +234,7 @@ Patches have also been contributed by: Jan Kiszka <jan.kiszka(a)siemens.com> Ryan Woodsmall <rwoodsmall(a)gmail.com> Wido den Hollander <wido(a)widodh.nl> + William Jon McCann <jmccann(a)redhat.com> [....send patches to get your name here....] diff --git a/daemon/libvirtd-config.c b/daemon/libvirtd-config.c index 471236c..8b95969 100644 --- a/daemon/libvirtd-config.c +++ b/daemon/libvirtd-config.c @@ -205,16 +205,16 @@ daemonConfigFilePath(bool privileged, char **configfile) if (!(*configfile = strdup(SYSCONFDIR "/libvirt/libvirtd.conf"))) goto no_memory;

[libvirt] [PATCH qemu v2 0/6] -no-user-config option, move CPU models to /usr/share
by Eduardo Habkost 02 May '12

02 May '12

Changes v1 -> v2: - Move qemu_read_default_config_files() prototype to qemu-config.h - Make defconfig and userconfig variable bool - Coding style change Patches 1 to 4 just move some code around, patch 5 just adds the new option without adding any new config file. Patch 6 finally creates a /usr/share/qemu /cpus-x86_64.conf file, with the CPU models we currently have on Qemu. Reference to previous discussion: - http://marc.info/?l=qemu-devel&m=133278877315665 Eduardo Habkost (6): move code to read default config files to a separate function (v2) eliminate arch_config_name variable move list of default config files to an array vl.c: change 'defconfig' variable to bool implement -no-user-config command-line option (v2) move CPU definitions to /usr/share/qemu/cpus-x86_64.conf (v2) Makefile | 12 +++- arch_init.c | 32 ++++++++- arch_init.h | 2 - qemu-config.h | 4 + qemu-options.hx | 16 ++++- sysconfigs/target/cpus-x86_64.conf | 128 ++++++++++++++++++++++++++++++++++ sysconfigs/target/target-x86_64.conf | 128 ---------------------------------- vl.c | 18 ++--- 8 files changed, 193 insertions(+), 147 deletions(-) create mode 100644 sysconfigs/target/cpus-x86_64.conf -- 1.7.3.2

[libvirt] [PATCH 1/2] virsh: make -h always give help
by Eric Blake 01 May '12

01 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=817244 mentions that unlike most other tools, where --help or --version prevent all further parsing of all later options, virsh was strange in that --version stopped parsing but --help tried to plow on to the end. There was no rationale for this original implementation (since 2005!), so I think we can safely conform to common usage patterns. * tools/virsh.c (main): Drop useless 'help' variable. --- I think the intent might have been to someday allow: virsh -h foo to be short for virsh help foo but since that hasn't been implemented in 7 years, I think it is smarter to be consistent with other tools instead. tools/virsh.c | 15 ++------------- 1 files changed, 2 insertions(+), 13 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index e177684..7159744 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -20179,7 +20179,6 @@ vshAllowedEscapeChar(char c) static bool vshParseArgv(vshControl *ctl, int argc, char **argv) { - bool help = false; int arg, len; struct option opt[] = { {"debug", required_argument, NULL, 'd'}, @@ -20206,7 +20205,8 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) } break; case 'h': - help = true; + vshUsage(); + exit(EXIT_SUCCESS); break; case 'q': ctl->quiet = true; @@ -20251,17 +20251,6 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) } } - if (help) { - if (optind < argc) { - vshError(ctl, _("extra argument '%s'.

[libvirt] [PATCH] util: fix crash when starting macvtap interfaces
by Laine Stump 01 May '12

01 May '12

This patch resolves https://bugzilla.redhat.com/show_bug.cgi?id=815270 The function virNetDevMacVLanVPortProfileRegisterCallback() takes an arg "virtPortProfile", and was checking it for non-NULL before using it. However, the prototype for virNetDevMacVLanPortProfileRegisterCallback had marked that arg with ATTRIBUTE_NONNULL(). Contrary to what one may think, ATTRIBUTE_NONNULL() does not provide any guarantee that an arg marked as such really is always non-null; the only effect to the code generated by gcc, is that gcc *assumes* it is non-NULL; this results in, for example, the check for a non-NULL value being optimized out. (Unfortunately, this code removal only occurs when optimization is enabled, and I am in the habit of doing local builds with optimization off to ease debugging, so the bug didn't show up in my earlier local testing). In general, virPortProfile might always be NULL, so it shouldn't be marked as ATTRIBUTE_NONNULL. One other function prototype made this same error, so this patch fixes it as well. --- src/util/virnetdevmacvlan.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/virnetdevmacvlan.h b/src/util/virnetdevmacvlan.h index 2299f1d..07d54e2 100644 --- a/src/util/virnetdevmacvlan.h +++ b/src/util/virnetdevmacvlan.h @@ -82,7 +82,7 @@ int virNetDevMacVLanRestartWithVPortProfile(const char *cr_ifname, virNetDevVPortProfilePtr virtPortProfile, enum virNetDevVPortProfileOp vmOp) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4) ATTRIBUTE_NONNULL(5) ATTRIBUTE_RETURN_CHECK; + ATTRIBUTE_NONNULL(4) ATTRIBUTE_RETURN_CHECK; int virNetDevMacVLanVPortProfileRegisterCallback(const char *ifname, const unsigned char *macaddress , @@ -91,5 +91,5 @@ int virNetDevMacVLanVPortProfileRegisterCallback(const char *ifname, virNetDevVPortProfilePtr virtPortProfile, enum virNetDevVPortProfileOp vmOp) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) -ATTRIBUTE_NONNULL(4) ATTRIBUTE_NONNULL(5) ATTRIBUTE_RETURN_CHECK; +ATTRIBUTE_NONNULL(4) ATTRIBUTE_RETURN_CHECK; #endif /* __UTIL_MACVTAP_H__ */ -- 1.7.10
