[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

[libvirt] [PATCH V13 0/5] Add DHCP snooping support to nwfilter
by Stefan Berger 01 May '12

01 May '12

This series of patches adds DHCP snooping support to libvirt's nwfilter subsystem. DHCP snooping detects DHCP leases obtained by a VM and automatically adjusts the network traffic filters to reflect the IP addresses with which a VM may send its traffic, thus for example preventing IP address spoofing. Once leases on IP addresses expire or if a VM gives up on a lease on an IP address, the filters are also adjusted. All leases are persisted and automatically applied upon a VM's restart. Leases are associated with the tuple of VM-UUID and interface MAC address. The following interface XML activates and uses the DHCP snooping: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> </filterref> </interface> Once an IP address has been detected on an interface, 'virsh dumpxml <vm>' would show the IP address lease in the format <IP address>,<lease timeout in seconds>: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> <parameter name='IP_LEASE' value='192.168.122.210,180'/> </filterref> </interface> Regards, David and Stefan
