[libvirt] [PATCH] conf: Don't deref NULL actual network in virDomainNetGetActualHostdev()
by Peter Krempa 05 Sep '13

05 Sep '13

In commit 991270db99690 I've used virDomainNetGetActualHostdev() to get the actual hostdev from a network when removing the network from the list to avoid leaving the hostdev in the list. I didn't notice that this function doesn't check if the actual network is allocated and dereferences it. This crashes the daemon when cleaning up a domain object in early startup phases when the actual network definition isn't allocated. When the actual definition isn't present, the hostdev that might correspond to it won't be present anyways so it's safe to return NULL. Thanks to Cole Robinson for noticing this problem. --- src/conf/domain_conf.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index cef4cf9..276c6ba 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -17875,6 +17875,7 @@ virDomainNetGetActualHostdev(virDomainNetDefPtr iface) if (iface->type == VIR_DOMAIN_NET_TYPE_HOSTDEV) return &iface->data.hostdev.def; if (iface->type == VIR_DOMAIN_NET_TYPE_NETWORK && + iface->data.network.actual && iface->data.network.actual->type == VIR_DOMAIN_NET_TYPE_HOSTDEV) { return &iface->data.network.actual->data.hostdev.def; } -- 1.8.3.2

[libvirt] [PATCH] libxl: Unconditionally call virSysinfoRead() on driver init

[libvirt] [PATCH] virsh: fix build on mingw, which lacks termios stuff
by Eric Blake 04 Sep '13

04 Sep '13

Recent patches to fix handling of Ctrl-C when interacting with ssh are not portable to mingw, which lacks termios handling. The simplest solution is to just compile that code out, and if someone ever appears that has a serious interest in getting virsh fully functional even with ssh connections, they can provide patches at that time. * tools/virsh.h (_vshControl): Make termattr conditional. * tools/virsh.c (vshTTYIsInterruptCharacter) (vshTTYDisableInterrupt, vshTTYRestore, cfmakeraw, vshTTYMakeRaw) (main): Likewise.

[libvirt] [PATCH 00/12] Various libxl driver improvements
by Jim Fehlig 04 Sep '13

04 Sep '13

This series contains several improvements for the libxl driver. Patches 1 and 2 are primarily code movement, putting code in files that are more consistent with other drivers. Patches 3 through 12 improve locking of the libxlDriverPrivate struct, similar to the work done in the QEMU and LXC drivers Obviously post-1.1.2 material, but would be nice to get it in soon thereafter for testing throughout the 1.1.3 cycle... Jim Fehlig (12): libxl: Move detection of autoballoon to libxl_conf libxl: Introduce libxl_domain.[ch] libxl: Earlier detection of not running on Xen libxl: Add libxl_version_info to libxlDriverPrivate libxl: libxl: Use per-domain ctx in libxlMakeDomCreateInfo libxl: User per-domain ctx in libxlDomainGetInfo libxl: Introduce libxlDriverConfig object libxl: Use atomic ops for driver->nactive libxl: Add comments to libxlDriverPrivate fields libxl: Move driver lock/unlock to libxl_conf libxl: Remove unnecessary driver locking libxl: Add libxlDomObjFromDomain po/POTFILES.in | 1 + src/Makefile.am | 1 + src/libxl/libxl_conf.c | 149 +++++- src/libxl/libxl_conf.h | 87 +-- src/libxl/libxl_domain.c | 469 ++++++++++++++++ src/libxl/libxl_domain.h | 61 +++ src/libxl/libxl_driver.c | 1329 ++++++++++------------------------------------ 7 files changed, 1010 insertions(+), 1087 deletions(-) create mode 100644 src/libxl/libxl_domain.c create mode 100644 src/libxl/libxl_domain.h -- 1.8.1.4
