[libvirt] [PATCH] qemu: fix qemuDomainSupportsPCI() for ARM machines of "virt" machinetype
by Laine Stump 11 Aug '15

11 Aug '15

Commit e8d5517 updated the domain post-parse to automatically add pcie-root et al for certain ARM "virt" machinetypes, but didn't update the function qemuDomainSupportsPCI() which is called later on when we are auto-assigning PCI addresses and default settings for the PCI controller <model> and <target> attributes. The result was that PCI addresses weren't assigned, and the controllers didn't have their attribute default values set, leading to an error when the domain was started, e.g.: internal error: autogenerated dmi-to-pci-bridge options not set This patch duplicates the check made in the earlier patch, so that PCI address auto-assignment and target/model default values will be set. --- The example Cole gave in his email reporting this bug is fixed by this patch. src/qemu/qemu_command.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ae03618..84cbfe1 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1742,7 +1742,7 @@ qemuCollectPCIAddress(virDomainDefPtr def ATTRIBUTE_UNUSED, } static bool -qemuDomainSupportsPCI(virDomainDefPtr def) +qemuDomainSupportsPCI(virDomainDefPtr def, virQEMUCapsPtr qemuCaps) { if ((def->os.arch != VIR_ARCH_ARMV7L) && (def->os.arch != VIR_ARCH_AARCH64)) return true; @@ -1750,6 +1750,11 @@ qemuDomainSupportsPCI(virDomainDefPtr def) if (STREQ(def->os.machine, "versatilepb")) return true; + if ((STREQ(def->os.machine, "virt") || + STRPREFIX(def->os.machine, "virt-")) && + virQEMUCapsGet(qemuCaps, QEMU_CAPS_OBJECT_GPEX)) + return true; + return false; } @@ -2267,7 +2272,7 @@ qemuDomainAssignPCIAddresses(virDomainDefPtr def, if (!(addrs = qemuDomainPCIAddressSetCreate(def, nbuses, false))) goto cleanup; - if (qemuDomainSupportsPCI(def)) { + if (qemuDomainSupportsPCI(def, qemuCaps)) { if (qemuValidateDevicePCISlotsChipsets(def, qemuCaps, addrs) < 0) goto cleanup; -- 2.1.0

[libvirt] [PATCH] virNetSocketCheckProtocols: handle EAI_NONAME as IPv6 unavailable
by Guido Günther 11 Aug '15

[libvirt] [PATCHv2] util: don't overwrite stack when getting ethtool gfeatures
by Laine Stump 11 Aug '15

11 Aug '15

This fixes the crash described here: https://www.redhat.com/archives/libvir-list/2015-August/msg00162.html In short, we were calling ioctl(SIOCETHTOOL) pointing to a too-short object that was a local on the stack, resulting in the memory past the end of the object being overwritten. This was because the struct used by the ETHTOOL_GFEATURES command of SIOCETHTOOL ends with a 0-length array, but we were telling ethtool that it could use 2 elements on the array. The fix is to allocate the necessary memory with VIR_ALLOC_VAR(), including the extra length needed for a 2 element array at the end. --- V2 difference: eliminate all the other cleanups that were in V1, just fix the crash.

[libvirt] [PATCH] util: fix virNetDevSendEthtoolIoctl() and its callers
by Laine Stump 11 Aug '15

11 Aug '15

This started out as a fix for a crash reported in IRC and on libvir-list: https://www.redhat.com/archives/libvir-list/2015-August/msg00162.html but as I examined the existing code I found so many nits to pick that I just did them all. The most important fix here is that virNetDevGetFeatures was creating a struct ethtool_gfeatures object as a local on the stack and, although the struct is defined with 0 elements in its features array, we were telling the ethtool ioctl that we had made space for 2 elements. This led to a crash, as outlined in the email above. The fix for this is to allocate the memory for the ethtool_gfeatures object using VIR_ALLOC_N to a char*, giving it the length: sizeof(ethtool_gfeatures) + (2 * sizeof(ethtool_get_features_block) because VIR_ALLOC_N is a macro and fails when you try to typecast a pointer to char* within the invocation, I made a union that has both a char* and an ethtool_gfeatures*, and used the char* of the union for VIR_ALLOC_N, and the other for everything else. Beyond that crash fixer, the following fixups were made to the hierarchy of functions between virNetDevGetFeatures() and virNetDevSendEthtoolIoctl(): * macros used to examine the gfeatures bits were renamed from FEATURE_* to GFEATURE_* virNetDevSentEthtoolIoctl(): * no need to initialize sock to -1, since it is always set at the top of the function. * remove VIR_DEBUG log (and subsequent *skipping* of error log!) when errno is EPERM, EINVAL or EOPNOTSUPP. If one of those errors were ever encountered, this would have been *very* problematic, as it would have led to one of those situations where virsh reports "an error was encountered but the cause is unknown" (or whatever the message is when we have an error but no log message). * always call VIR_FORCE_CLOSE(sock) since we know that sock is either a valid fd, or else -1 (which VIR_FORCE_CLOSE() will skip). virNetDevFeatureAvailable() * simplify it - no need for ret. * follow libvirt convention of checking for "bobLobLaw(lawblog) < 0" instead of "!bobLobLaw(lawblog)". virNetDevGFeatureAvailable() * eliminate this function, as it was ill-conceived (it really was only checking for one gfeature (TX_UDP_TNL), not *any* gfeature. virNetDevGetFeatures() * move all data tables (struct elem) out of the function so that they will be statics instead of taking up space on the stack. * remove pointless/incorrect initialization of i = -1. * remove unnecessary static initialization of struct ethtool_value cmd * put struct ethtool_gfeatures into a union with a char* as described above * use libvirt convention of checking return from virNetDevFeatureAvailable() < 0, instead of "!virNetDevFeatureAvailable()", and immediately return to caller with an error when virNetDevFeatureAvailable() returns an error (previously it was ignored). * remove superfluous size_t j, and just re-use i instead. * runtime allocation/free of proper size object for ethtoolfeatures as described above. * directly call virNetDevSentEthtoolIoctl() instead of now defunct virNetDevGFeatureAvailable(). === NB: This patch does *not* attempt to determine the proper number of elements for the gfeature array at runtime, as proposed in this patch: https://www.redhat.com/archives/libvir-list/2015-August/msg00263.html since that wasn't the cause of the crash. I'll leave it up to Moshe to repost that patch rebased around this one (or whatever ends up being pushed) if he thinks there is value to it. Also - as I mentioned in earlier mail in response to the crash, I noticed when looking into the gfeatures ethtool code that it looks to me like TX_UDP_TNL should actually be 26 rather than 25, but I may be missing something. Moshe - can you either confirm or deny that?

[libvirt] [PATCH] network: validate network NAT range
by Laine Stump 11 Aug '15

11 Aug '15

This patch modifies virSocketAddrGetRange() to function properly when the containing network/prefix of the address range isn't known, for example in the case of the NAT range of a virtual network (since it is a range of addresses on the *host*, not within the network itself). We then take advantage of this new functionality to validate the NAT range of a virtual network. Extra test cases are also added to verify that virSocketAddrGetRange() works properly in both positive and negative cases when the network pointer is NULL. This is the *real* fix for: https://bugzilla.redhat.com/show_bug.cgi?id=985653 Commits 1e334a and 48e8b9 had earlier been pushed as fixes for that bug, but I had neglected to read the report carefully, so instead of fixing validation for the NAT range, I had fixed validation for the DHCP range. sigh. --- The changes to virSocketAddrGetRange() *look* like they are extensive, but really they almost completely consist of: 1) reordering and reindenting some of the checks so that they are only executed when we have a valid network address 2) modifying the error messages that could occur when there isn't a valid network so that they don't attempt to use the network address or prefix. src/conf/network_conf.c | 4 ++ src/util/virsocketaddr.c | 168 +++++++++++++++++++++++++---------------------- tests/sockettest.c | 46 ++++++++++++- 3 files changed, 136 insertions(+), 82 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index f77af15..b8d918c 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1731,6 +1731,10 @@ virNetworkForwardNatDefParseXML(const char *networkName, goto cleanup; } + /* verify that start <= end */ + if (virSocketAddrGetRange(&def->addr.start, &def->addr.end, NULL, 0) < 0) + goto cleanup; + /* ports for SNAT and MASQUERADE */ nNatPorts = virXPathNodeSet("./port", ctxt, &natPortNodes); if (nNatPorts < 0) { diff --git a/src/util/virsocketaddr.c b/src/util/virsocketaddr.c index 81539b3..900aa5b 100644 --- a/src/util/virsocketaddr.c +++ b/src/util/virsocketaddr.c @@ -628,126 +628,136 @@ virSocketAddrGetRange(virSocketAddrPtr start, virSocketAddrPtr end, virSocketAddr netmask; char *startStr = NULL, *endStr = NULL, *netStr = NULL; - if (start == NULL || end == NULL || network == NULL) { + if (start == NULL || end == NULL) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("NULL argument - %p %p %p"), start, end, network); + _("NULL argument - %p %p"), start, end); goto error; } startStr = virSocketAddrFormat(start); endStr = virSocketAddrFormat(end); - netStr = virSocketAddrFormat(network); - if (!(startStr && endStr && netStr)) + if (!startStr || !endStr) goto error; /*error already reported */ - if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(end) || - VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(network)) { + if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(end)) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("mismatch of address family in " - "range %s - %s for network %s"), - startStr, endStr, netStr); + _("mismatch of address family in range %s - %s"), + startStr, endStr); goto error; } - if (prefix < 0 || - virSocketAddrPrefixToNetmask(prefix, &netmask, - VIR_SOCKET_ADDR_FAMILY(network)) < 0) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("bad prefix %d for network %s when " - " checking range %s - %s"), - prefix, netStr, startStr, endStr); - goto error; - } - - /* both start and end of range need to be in the same network as - * "network" - */ - if (virSocketAddrCheckNetmask(start, network, &netmask) <= 0 || - virSocketAddrCheckNetmask(end, network, &netmask) <= 0) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("range %s - %s is not entirely within " - "network %s/%d"), - startStr, endStr, netStr, prefix); - goto error; - } - - if (VIR_SOCKET_ADDR_IS_FAMILY(start, AF_INET)) { - virSocketAddrIPv4 t1, t2; - virSocketAddr netaddr, broadcast; + if (network) { + /* some checks can only be done if we have details of the + * network the range should be within + */ + if (!(netStr = virSocketAddrFormat(network))) + goto error; - if (virSocketAddrBroadcast(network, &netmask, &broadcast) < 0 || - virSocketAddrMask(network, &netmask, &netaddr) < 0) { + if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(network)) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("failed to construct broadcast or network " - "address for network %s/%d"), - netStr, prefix); + _("mismatch of address family in " + "range %s - %s for network %s"), + startStr, endStr, netStr); goto error; } - /* Don't allow the start of the range to be the network - * address (usually "...0") or the end of the range to be the - * broadcast address (usually "...255").
