[libvirt] [PATCH] qemu: Fix bogus warning about uninitialized saveptr
by Jiri Denemark 06 Jan '11

06 Jan '11

The warning is bogus since strtok_r doesn't use the value when it's first called and initializes it for the following calls. --- src/qemu/qemu_command.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index bde3904..7dd8e03 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -5621,7 +5621,7 @@ virDomainDefPtr qemuParseCommandLine(virCapsPtr caps, if (def->ndisks > 0) { const char *ceph_args = qemuFindEnv(progenv, "CEPH_ARGS"); if (ceph_args) { - char *hosts, *port, *saveptr, *token; + char *hosts, *port, *saveptr = NULL, *token; virDomainDiskDefPtr first_rbd_disk = NULL; for (i = 0 ; i < def->ndisks ; i++) { virDomainDiskDefPtr disk = def->disks[i]; -- 1.7.3.4

[libvirt] [PATCH] virsh: print error in case of cellno is invalid

[libvirt] [PATCH] Log an error on attempts to add a NAT rule for non-IPv4 addresses
by Laine Stump 06 Jan '11

06 Jan '11

Although the upper-layer code protected against it, it was possible to call iptablesForwardMasquerade() with an IPv6 address and have it attempt to add a rule to the MASQUERADE chain of ip6tables (which doesn't exist). This patch changes that function to check the protocol of the given address, generate an error log if it's not IPv4 (AF_INET), and finally hardcodes all the family parameters sent down to lower-level functions. --- src/util/iptables.c | 17 +++++++++++++---- 1 files changed, 13 insertions(+), 4 deletions(-) diff --git a/src/util/iptables.c b/src/util/iptables.c index 6770fe0..59f5cc7 100644 --- a/src/util/iptables.c +++ b/src/util/iptables.c @@ -761,10 +761,19 @@ iptablesForwardMasquerade(iptablesContext *ctx, if (!(networkstr = iptablesFormatNetwork(netaddr, prefix))) return -1; + if (!VIR_SOCKET_IS_FAMILY(netaddr, AF_INET)) { + /* Higher level code *should* guaranteee it's impossible to get here. */ + iptablesError(VIR_ERR_INTERNAL_ERROR, + _("Attempted to NAT '%s'.

[libvirt] [PATCH] Improve error reporting when parsing dhcp info for virtual networks
by Laine Stump 06 Jan '11

06 Jan '11

This is partially in response to https://bugzilla.redhat.com/show_bug.cgi?id=653300 The crash in that report was coincidentally fixed when we switched from using inet_pton() to using virSocketParseAddr(), but the absence of an ip address in a dhcp static host definition was still silently ignored (and that entry discarded from the saved XML). This patch turns that into a logged failure; likewise if the entry has neither a mac address nor a name attribute (the entry is useless without at least one of those, plus an ip address). Since the network name is now pulled into this function in order for those error logs to be more informative, the other error messages in the function have also been changed to take advantage. --- src/conf/network_conf.c | 32 +++++++++++++++++++------------- 1 files changed, 19 insertions(+), 13 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 420b94a..fe91617 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -295,7 +295,8 @@ int virNetworkIpDefNetmask(const virNetworkIpDefPtr def, static int -virNetworkDHCPRangeDefParseXML(virNetworkIpDefPtr def, +virNetworkDHCPRangeDefParseXML(const char *networkName, + virNetworkIpDefPtr def, xmlNodePtr node) { @@ -333,8 +334,8 @@ virNetworkDHCPRangeDefParseXML(virNetworkIpDefPtr def, range = virSocketGetRange(&saddr, &eaddr); if (range < 0) { virNetworkReportError(VIR_ERR_XML_ERROR, - _("dhcp range '%s' to '%s' invalid"), - start, end); + _("Invalid dhcp range '%s' to '%s' in network '%s'"), + start, end, networkName); VIR_FREE(start); VIR_FREE(end); return -1; @@ -359,33 +360,38 @@ virNetworkDHCPRangeDefParseXML(virNetworkIpDefPtr def, if ((mac != NULL) && (virParseMacAddr(mac, &addr[0]) != 0)) { virNetworkReportError(VIR_ERR_INTERNAL_ERROR, - _("cannot parse MAC address '%s'"), - mac); + _("Cannot parse MAC address '%s' in network '%s'"), + mac, networkName); VIR_FREE(mac); } name = virXMLPropString(cur, "name"); if ((name != NULL) && (!c_isalpha(name[0]))) { virNetworkReportError(VIR_ERR_INTERNAL_ERROR, - _("cannot use name address '%s'"), - name); + _("Cannot use name address '%s' in network '%s'"), + name, networkName); VIR_FREE(name); } /* * You need at least one MAC address or one host name */ if ((mac == NULL) && (name == NULL)) { + virNetworkReportError(VIR_ERR_XML_ERROR, + _("Static host definition in network '%s' must have mac or name attribute"), + networkName); VIR_FREE(mac); VIR_FREE(name); - cur = cur->next; - continue; + return -1; } ip = virXMLPropString(cur, "ip"); - if (virSocketParseAddr(ip, &inaddr, AF_UNSPEC) < 0) { + if ((ip == NULL) || + (virSocketParseAddr(ip, &inaddr, AF_UNSPEC) < 0)) { + virNetworkReportError(VIR_ERR_XML_ERROR, + _("Missing IP address in static host definition for network '%s'"), + networkName); VIR_FREE(ip); VIR_FREE(mac); VIR_FREE(name); - cur = cur->next; - continue; + return -1; } VIR_FREE(ip); if (VIR_REALLOC_N(def->hosts, def->nhosts + 1) < 0) { @@ -541,7 +547,7 @@ virNetworkIPParseXML(const char *networkName, while (cur != NULL) { if (cur->type == XML_ELEMENT_NODE && xmlStrEqual(cur->name, BAD_CAST "dhcp")) { - result = virNetworkDHCPRangeDefParseXML(def, cur); + result = virNetworkDHCPRangeDefParseXML(networkName, def, cur); if (result) goto error; -- 1.7.3.4

[libvirt] [PATCH] qemu driver: use lseek64 for setting position in logfile
by Stefan Berger 05 Jan '11

05 Jan '11

While doing some testing with Qemu and creating huge logfiles I encountered the case where the VM could not start anymore due to the lseek() to the end of the Qemu VM's log file failing. The patch below replaces the two occurrences of lseek() in the relevant path with lseek64() and solves this problem. It may be a good idea to look at other occurrences of lseek() as well whether they should be replaced. off_t is 8 bytes long (64 bit), so it doesn't need to be replaced with the explicit off64_t. To reproduce this error, you could do the following: dd if=/dev/zero of=/var/log/libvirt/qemu/<name of VM>.log bs=1024 count=$((1024*2048)) and you should get an error like this: error: Failed to start domain <name of VM> error: Unable to seek to -2147482651 in /var/log/libvirt/qemu/<name of VM>.log: Success Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com> --- src/qemu/qemu_driver.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) Index: libvirt-acl/src/qemu/qemu_driver.c =================================================================== --- libvirt-acl.orig/src/qemu/qemu_driver.c +++ libvirt-acl/src/qemu/qemu_driver.c @@ -238,7 +238,7 @@ qemudLogReadFD(const char* logDir, const VIR_FREE(logfile); return -1; } - if (pos < 0 || lseek(fd, pos, SEEK_SET) < 0) { + if (pos < 0 || lseek64(fd, pos, SEEK_SET) < 0) { virReportSystemError(pos < 0 ? 0 : errno, _("Unable to seek to %lld in %s"), (long long) pos, logfile); @@ -2624,7 +2624,7 @@ static int qemudStartVMDaemon(virConnect enum virVMOperationType vmop) { int ret; unsigned long long qemuCmdFlags; - int pos = -1; + off_t pos = -1; char ebuf[1024]; char *pidfile = NULL; int logfile = -1; @@ -2839,7 +2839,7 @@ static int qemudStartVMDaemon(virConnect virCommandWriteArgLog(cmd, logfile); - if ((pos = lseek(logfile, 0, SEEK_END)) < 0) + if ((pos = lseek64(logfile, 0, SEEK_END)) < 0) VIR_WARN("Unable to seek to end of logfile: %s", virStrerror(errno, ebuf, sizeof ebuf));

[libvirt] [PATCH v2] qemu driver: use lseek64 for setting position in logfile
by Stefan Berger 05 Jan '11

05 Jan '11

V2: - removed replacements of lseek() to lseek64() from patch While doing some testing with Qemu and creating huge logfiles I encountered the case where the VM could not start anymore due to the lseek() to the end of the Qemu VM's log file failing. The patch below fixes the problem by replacing the previously used 'int' with 'off_t'. To reproduce this error, you could do the following: dd if=/dev/zero of=/var/log/libvirt/qemu/<name of VM>.log bs=1024 count=$((1024*2048)) and you should get an error like this: error: Failed to start domain <name of VM> error: Unable to seek to -2147482651 in /var/log/libvirt/qemu/<name of VM>.log: Success Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com> --- src/qemu/qemu_driver.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) Index: libvirt-acl/src/qemu/qemu_driver.c =================================================================== --- libvirt-acl.orig/src/qemu/qemu_driver.c +++ libvirt-acl/src/qemu/qemu_driver.c @@ -2624,7 +2624,7 @@ static int qemudStartVMDaemon(virConnect enum virVMOperationType vmop) { int ret; unsigned long long qemuCmdFlags; - int pos = -1; + off_t pos = -1; char ebuf[1024]; char *pidfile = NULL; int logfile = -1;
