[libvirt] macvtap - no incoming ipv6 traffic processed on kvm host unless i start tcpdump on interface

by Stefan Bauer

Dear folks, I'm using for the first time macvtap interface for my virtual machines in bridged mode. VM -> HOST -> Router -> INTERNET This works fine for ipv4 connectivity. For ipv6 my virtual machines receive appropriate v6 address from radvd but are not able to receive answer packages from outside (ping -t -6 google.de was started inside VM). I see the ping request/response on my router: 14:10:52.147834 IP6 2a01:198:200:8350:dc8b:cd82:144e:14eb > 2a00:1450:4001:806::1018: ICMP6, echo request, seq 108, length 40 14:10:52.182073 IP6 2a00:1450:4001:806::1018 > 2a01:198:200:8350:dc8b:cd82:144e:14eb: ICMP6, echo reply, seq 108, length 40 14:10:55.179874 IP6 2a01:198:200:350::2 > 2a00:1450:4001:806::1018: ICMP6, destination unreachable, unreachable address 2a01:198:200:8350:dc8b:cd82:144e:14eb, length 88 But i do not receive the reply on the VM. However on the KVM host - when i start a tcpdump on the macvtap interface with root@s1:~# tcpdump -ni macvtap0 ip6 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on macvtap0, link-type EN10MB (Ethernet), capture size 262144 bytes 14:12:37.134516 IP6 2a01:198:200:8350:dc8b:cd82:144e:14eb > 2a00:1450:4001:806::1018: ICMP6, echo request, seq 129, length 40 14:12:37.188529 IP6 fe80::12fe:edff:fee6:cfa > ff02::1:ff4e:14eb: ICMP6, neighbor solicitation, who has 2a01:198:200:8350:dc8b:cd82:144e:14eb, length 32 14:12:37.189040 IP6 2a01:198:200:8350:dc8b:cd82:144e:14eb > fe80::12fe:edff:fee6:cfa: ICMP6, neighbor advertisement, tgt is 2a01:198:200:8350:dc8b:cd82:144e:14eb, length 32 14:12:37.189202 IP6 2a00:1450:4001:806::1018 > 2a01:198:200:8350:dc8b:cd82:144e:14eb: ICMP6, echo reply, seq 129, length 40 packages starting to get processed and VM receives replies. Any idea what is happening here? Cheers, Stefan

[libvirt] [PATCH 0/9] Duplicate storage pool source refactoring and checks

by John Ferlan

A precursor to some changes I'm working on - I figured it was better not to hoard the patches and then drop a 15 patch series... Anyway, patches 1-4 refactor the iSCSI <source> duplicate checks into a separate subroutine. While I was at it, I realized the Host checks are duplicate of the NETFS check - so I further separated things out. As I was looking at other possible defs I realized not all of the proposed storage pool defs go through duplicate checks because the switch statement had the 'default:' case - so I removed that, added all the options with the hope that new storage pool types will add their own checking. This left me with a bit of sleuthing for cases I added. I was able to determine that Sheepdog and Gluster both have the possibility of "a" single source host, so I added that check as it doesn't seem like it would be a good idea to have two storage pools looking at the same gluster/sheepdog source For the zfs pool it seems that it's like the DISK, LOGICAL, and FS pools with regard to not having duplicate devices in the pool For mpath there doesn't seem to be any need, but I could be wrong For rbd it wasn't completely clear what to check since multiple hosts are allowed for a single pool - I suppose a proposed definition should check that none of it's definitions match, but then again I'm not clear so I left it alone John Ferlan (9): storage: Refactor iSCSI Source matching storage: Refactor matchISCSISource storage: Invert logic for matchISCSISource storage: Create matchPoolSourceHost storage: Use matchPoolSourceHost for NETFS storage: Remove default from switch in virStoragePoolSourceFindDuplicate storage: Add duplicate host check for Sheepdog pool def storage: Add duplicate host check for Gluster pool def storage: Add duplicate devices check for zfs pool def src/conf/storage_conf.c | 59 +++++++++++++++++++++++++++++++++++-------------- 1 file changed, 43 insertions(+), 16 deletions(-) -- 2.1.0

[libvirt] [PATCH] build: include correct header for time()

by Eric Blake

Found by ./autobuild.sh during a mingw cross-compile: Commit 8a96e87 was not innocuous - glibc happens to leak the definition of time() through other headers, so that even without <sys/select.h>, virrandom.c compiled just fine. But on mingw, we were not so lucky; <sys/select.h> was important for its side effect of dragging in <time.h>, and we now have nothing providing the declaration of time(): ../../src/util/virrandom.c: In function 'virRandomOnceInit': ../../src/util/virrandom.c:65:5: error: implicit declaration of function 'time' [-Werror=implicit-function-declaration] unsigned int seed = time(NULL) ^ getpid(); ^ ../../src/util/virrandom.c:65:5: error: nested extern declaration of 'time' [-Werror=nested-externs] Signed-off-by: Eric Blake <eblake(a)redhat.com> --- Pushing under the build-breaker rule. src/util/virrandom.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/util/virrandom.c b/src/util/virrandom.c index 4301f3f..67a8bd0 100644 --- a/src/util/virrandom.c +++ b/src/util/virrandom.c @@ -1,5 +1,5 @@ /* - * Copyright (C) 2012-2014 Red Hat, Inc. + * Copyright (C) 2012-2015 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -25,6 +25,7 @@ #include <inttypes.h> #include <math.h> #include <strings.h> +#include <time.h> #include "virrandom.h" #include "virthread.h" -- 2.1.0

[libvirt] [PATCH] qemu: monitor: Add check that monitor is non-null to specific commands

by Peter Krempa

Our monitor locking and cleanup code is weird as it allows to remove the monitor object pointer while we are in the monitor. Additionally EVERY api is using the vm private data after @vm was unlocked. This leads to an unpleasant situation, where when qemu crashes during a monitor session while a command is executed (and locks are down), the priv->mon pointer gets cleared (@vm is unlocked). The next monitor call then crashes on commands that did not check if the monitor is non-NULL. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1209813 and few other possible crashes --- Since this is a workaround rather than a proper fix I'd normally not go this way, but untangling the monitor mess won't be easy so I'll fix the symptoms first. src/qemu/qemu_monitor.c | 42 ++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor.h | 12 +++++------- 2 files changed, 47 insertions(+), 7 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 2b0e1a5..e8403be 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -1171,6 +1171,12 @@ qemuMonitorUpdateVideoMemorySize(qemuMonitorPtr mon, int ret = -1; char *path = NULL; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) { ret = qemuMonitorFindObjectPath(mon, "/", videoName, &path); if (ret < 0) { @@ -1886,6 +1892,12 @@ qemuMonitorBlockStatsUpdateCapacity(qemuMonitorPtr mon, { VIR_DEBUG("mon=%p, stats=%p, backing=%d", mon, stats, backingChain); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (!mon->json) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", _("block capacity/size info requires JSON monitor")); @@ -3246,6 +3258,12 @@ qemuMonitorAddObject(qemuMonitorPtr mon, mon, type, objalias, props); int ret = -1; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) { ret = qemuMonitorJSONAddObject(mon, type, objalias, props); } else { @@ -3265,6 +3283,12 @@ qemuMonitorDelObject(qemuMonitorPtr mon, VIR_DEBUG("mon=%p objalias=%s", mon, objalias); int ret = -1; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONDelObject(mon, objalias); else @@ -3453,6 +3477,12 @@ qemuMonitorBlockCommit(qemuMonitorPtr mon, const char *device, "bandwidth=%llu", mon, device, top, base, NULLSTR(backingName), bandwidth); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONBlockCommit(mon, device, top, base, backingName, bandwidth); @@ -3482,6 +3512,12 @@ qemuMonitorDiskNameLookup(qemuMonitorPtr mon, virStorageSourcePtr top, virStorageSourcePtr target) { + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return NULL; + } + if (!mon->json) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", _("JSON monitor is required")); @@ -3592,6 +3628,12 @@ qemuMonitorBlockJob(qemuMonitorPtr mon, mon, device, NULLSTR(base), NULLSTR(backingName), bandwidth, mode, modern); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONBlockJob(mon, device, base, backingName, bandwidth, mode, modern); diff --git a/src/qemu/qemu_monitor.h b/src/qemu/qemu_monitor.h index a3514cf..7e62139 100644 --- a/src/qemu/qemu_monitor.h +++ b/src/qemu/qemu_monitor.h @@ -246,7 +246,7 @@ void qemuMonitorSetOptions(qemuMonitorPtr mon, virJSONValuePtr options) int qemuMonitorUpdateVideoMemorySize(qemuMonitorPtr mon, virDomainVideoDefPtr video, const char *videName) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); int qemuMonitorHMPCommandWithFd(qemuMonitorPtr mon, const char *cmd, int scm_fd, @@ -381,7 +381,7 @@ int qemuMonitorGetAllBlockStatsInfo(qemuMonitorPtr mon, int qemuMonitorBlockStatsUpdateCapacity(qemuMonitorPtr mon, virHashTablePtr stats, bool backingChain) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2); + ATTRIBUTE_NONNULL(2); int qemuMonitorGetBlockExtent(qemuMonitorPtr mon, const char *dev_name, @@ -730,15 +730,13 @@ int qemuMonitorBlockCommit(qemuMonitorPtr mon, const char *base, const char *backingName, unsigned long long bandwidth) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4); bool qemuMonitorSupportsActiveCommit(qemuMonitorPtr mon); char *qemuMonitorDiskNameLookup(qemuMonitorPtr mon, const char *device, virStorageSourcePtr top, virStorageSourcePtr target) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4); int qemuMonitorArbitraryCommand(qemuMonitorPtr mon, const char *cmd, @@ -774,7 +772,7 @@ int qemuMonitorBlockJobInfo(qemuMonitorPtr mon, const char *device, virDomainBlockJobInfoPtr info, unsigned long long *bandwidth) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); int qemuMonitorOpenGraphics(qemuMonitorPtr mon, const char *protocol, -- 2.3.5
