[Libvir] [PATCH] Don't access line[-1] for a zero-length "line" from fgets.
by Jim Meyering 21 Jan '08

21 Jan '08

In reviewing the StorageAPI patches, I saw that some bogus input could cause a segfault. There's similar code in libvirt.c, so this fixes both. Note that virsh.c does this, too, but it already has the required guard. The src/libvirt.c patch applies to the trunk, but isn't a big deal, since it's in the sample AuthCallback function. The storage_backend.c part applies to the work-in-progress mercurial queue, but does matter, because we have no guarantee what the exec'd command will output. Don't access line[-1] for a zero-length "line" from fgets. A NUL byte at beginning of input, or just after a newline would provoke an invalid buf[-1] access (possible segfault). * src/libvirt.c (virConnectAuthCallbackDefault): * src/storage_backend.c (virStorageBackendRunProgRegex): Signed-off-by: Jim Meyering <meyering(a)redhat.com> --- src/libvirt.c | 6 ++++-- src/storage_backend.c | 2 +- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index 2972382..331c937 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -74,6 +74,7 @@ static int virConnectAuthCallbackDefault(virConnectCredentialPtr cred, for (i = 0 ; i < ncred ; i++) { char buf[1024]; char *bufptr = buf; + size_t len; if (printf("%s:", cred[i].prompt) < 0) return -1; @@ -92,8 +93,9 @@ static int virConnectAuthCallbackDefault(virConnectCredentialPtr cred, } return -1; } - if (buf[strlen(buf)-1] == '\n') - buf[strlen(buf)-1] = '\0'; + len = strlen(buf); + if (len != 0 && buf[len-1] == '\n') + buf[len-1] = '\0'; break; case VIR_CRED_PASSPHRASE: diff --git a/src/storage_backend.c b/src/storage_backend.c index 32a8d65..58d8642 100644 --- a/src/storage_backend.c +++ b/src/storage_backend.c @@ -338,7 +338,7 @@ int virStorageBackendRunProgRegex(virConnectPtr conn, while (fgets(line, sizeof(line), list) != NULL) { /* Strip trailing newline */ int len = strlen(line); - if (line[len-1] == '\n') + if (len && line[len-1] == '\n') line[len-1] = '\0'; for (i = 0 ; i <= maxReg && i < nregex ; i++) { -- 1.5.4.rc4.1.g1895

[Libvir] PATCH: Fix qemu-dm path in capabilities info
by Daniel P. Berrange 21 Jan '08

21 Jan '08

The current Xen capabilities XML data chooses between /usr/lib/xen/bin/qemu-dm and /usr/lib64/xen/bin/qemu-dm based on whether the guest arch is 64 bit. This is incorrect because the path is actually determined based on the host OS. Only x86_64 uses /usr/lib64, all other arches just use /usr/lib - even on ia64. So this patch changes the logic so that /usr/lib64 is only used if we see an x86_64 guest present - this implies host is x86_64 and that all guests whether 32 or 64bit shoudl use /usr/lib64 Dan. diff -r 38f2abccef9b src/xen_internal.c --- a/src/xen_internal.c Sun Jan 20 11:28:37 2008 -0500 +++ b/src/xen_internal.c Sun Jan 20 12:36:23 2008 -0500 @@ -2186,6 +2186,7 @@ xenHypervisorMakeCapabilitiesXML(virConn int ia64_be; } guest_archs[32]; int nr_guest_archs = 0; + int lib64 = 0; virBufferPtr xml; char *xml_str; @@ -2261,6 +2262,7 @@ xenHypervisorMakeCapabilitiesXML(virConn else if (strncmp (&token[subs[2].rm_so], "x86_64", 6) == 0) { model = "x86_64"; bits = 64; + lib64 = 1; } else if (strncmp (&token[subs[2].rm_so], "ia64", 4) == 0) { model = "ia64"; @@ -2376,7 +2378,7 @@ xenHypervisorMakeCapabilitiesXML(virConn <machine>pc</machine>\n\ <machine>isapc</machine>\n\ <loader>/usr/lib/xen/boot/hvmloader</loader>\n", - guest_archs[i].bits == 64 ?

[Libvir] Dom0 and entitlement
by Katti, Vadiraj (STSD-Openview) 21 Jan '08

21 Jan '08

Hi, I've some questions related to xen. Can anybody help me regarding the following questions. 1. Is dom0 a logical system(like any other vm's that are configured on it) ? If yes, then all xm commands should be applicable to it (ex : vcpu-set) . 2. /proc on dom0 reflects the physical or logical utilization. 3. Is there any entitelment concept in xen for cpu and memory? What is cpu weight used for and how is set. 4. virt-manager shows physical or logical utilization (cpu, memory) 5. How do i get the IP address of each of the guests from dom0 ? 6. What are the interfaces in domU to tell me that its a guest (or dom0) and also the type of virtualization ( eg. XEN/ VMWARE etc ) Thanks, Vadiraj

Hi, Rich I am trying to build libvirt on Windows for checking Xen domain operation. I am doing this based on following instruction. http://libvirt.org/windows.html Anyway Your document seems old. since the suggest patch is already applied to libvirt itself. Is there any plan to update it? Thanks Atsushi SAKAI

[Libvir] [PATCH] NIC should define in order
by Hiroyuki Kaguchi 21 Jan '08

21 Jan '08

Currently NIC definition order is reversed. If we set over 4-NICs for a domain by virt-install, this causes a network communication problem. This is because virtual mac to eth relation is lost. This patch fixes the NIC definition order. N.B. If less than 3-NICs, this problem does not occur.

[Libvir] PATCH: Add xstrtol variants for long long
by Daniel P. Berrange 20 Jan '08

20 Jan '08

Jim's xstrtol convenience function simplified the use of strtol, but only support the 'int' variant. For the storage drivers I need a similar function that will always be at minimum 64-bit since we may have files > 2 GB even on 32-bit. So this adds a variant of the xstrtol functions which use a long long / unsigned long long type Regards, Dan. diff -r 83e80c558f4d src/internal.h --- a/src/internal.h Wed Jan 16 09:28:01 2008 -0500 +++ b/src/internal.h Wed Jan 16 09:28:05 2008 -0500 @@ -304,6 +304,42 @@ xstrtol_ui(char const *s, char **end_ptr return 0; } +static inline int +xstrtol_ll(char const *s, char **end_ptr, int base, long long *result) +{ + long long val; + char *p; + int err; + + errno = 0; + val = strtoll(s, &p, base); + err = (errno || (!end_ptr && *p) || p == s || (long long) val != val); + if (end_ptr) + *end_ptr = p; + if (err) + return -1; + *result = val; + return 0; +} + +/* Just like xstrtol_i, above, but produce an "unsigned long long" value. */ +static inline int +xstrtol_ull(char const *s, char **end_ptr, int base, unsigned long long *result) +{ + unsigned long long val; + char *p; + int err; + + errno = 0; + val = strtoull(s, &p, base); + err = (errno || (!end_ptr && *p) || p == s || (unsigned long long) val != val); + if (end_ptr) + *end_ptr = p; + if (err) + return -1; + *result = val; + return 0; +} #ifdef __cplusplus } #endif /* __cplusplus */ Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] PATCH: RFC: env var to set default connection URI
by Daniel P. Berrange 20 Jan '08

20 Jan '08

Currently, if the app provides NULL as the connect URI, we always connect to a Xen hypervisor. virsh provides a VIR_DEFAULT_CONNECT_URI env var which can be used to override this. virt-install/virt-manager never use NULL, and now try to 'guess' a default URI based on whether /dev/kvm or /proc/xen exist. Users have requested that VIR_DEFAULT_CONNECT_URI apply to other apps besides virsh. So this patch adds support for LIBVIRT_DEFAULT_URI env variable which will be used if the connect URI is NULL. If that variable is not set it will still default to Xen. diff -r 673c98e11c78 src/libvirt.c --- a/src/libvirt.c Wed Jan 16 09:27:56 2008 -0500 +++ b/src/libvirt.c Wed Jan 16 09:28:00 2008 -0500 @@ -516,8 +516,13 @@ do_open (const char *name, xmlURIPtr uri; /* Convert NULL or "" to xen:/// for back compat */ - if (!name || name[0] == '\0') - name = "xen:///"; + if (!name || name[0] == '\0') { + char *defname = getenv("LIBVIRT_DEFAULT_URI"); + if (defname && *defname) + name = defname; + else + name = "xen:///"; + } /* Convert xen -> xen:/// for back compat */ if (!strcasecmp(name, "xen")) Regards, Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] PATCH: Fix compat for Xen 3.2.0

20 Jan '08

Xen 3.2.0 removed the sockets_per_node field from the nodeinfo data returned by XenD.

[Libvir] PATCH: make debug builds quiet by default

During development I like to have the --enable-debug flag enabled all the time because its very handy at times. I don't want it spewing to stderr all the time though, just because I turned on the compile option. So this patch adds an env variable 'LIBVIRT_DEBUG' which controls whether it is chatty or not. So with this patch you can use --enable-debug all the time, and just run LIBVIRT_DEBUG=1 ./src/virsh .... to turn it on for a particular test, or likewise for the daemon LIBVIRT_DEBUG=1 ./qemud/libvirtd Dan. libvirt.c | 64 +++++++++++++++++++++++++++++++++++--------------------------- 1 file changed, 37 insertions(+), 27 deletions(-) diff -r c747561694fc src/libvirt.c --- a/src/libvirt.c Tue Jan 08 23:52:20 2008 -0500 +++ b/src/libvirt.c Tue Jan 08 23:53:57 2008 -0500 @@ -59,10 +59,11 @@ static int initialized = 0; * are printed to stderr for debugging. */ #ifdef ENABLE_DEBUG +static int debugFlag = 0; #define DEBUG(fs,...) \ - fprintf (stderr, "libvirt: %s (" fs ")\n", __func__, __VA_ARGS__) + do { if (debugFlag) fprintf (stderr, "libvirt: %s (" fs ")\n", __func__, __VA_ARGS__); } while (0) #define DEBUG0 \ - fprintf (stderr, "libvirt: %s ()\n", __func__) + do { if (debugFlag) fprintf (stderr, "libvirt: %s ()\n", __func__); } while (0) #else #define DEBUG0 #define DEBUG(fs,...) @@ -179,10 +180,20 @@ int int virInitialize(void) { - DEBUG0; +#ifdef ENABLE_DEBUG + char *debugEnv; +#endif if (initialized) return(0); initialized = 1; + +#ifdef ENABLE_DEBUG + debugEnv = getenv("LIBVIRT_DEBUG"); + if (debugEnv && *debugEnv) + debugFlag = 1; +#endif + + DEBUG0; #if HAVE_WINSOCK2_H if (winsock_init () == -1) return -1; @@ -543,18 +554,17 @@ do_open (const char *name, } #ifdef ENABLE_DEBUG - fprintf (stderr, - "libvirt: do_open: name \"%s\" to URI components:\n" - " scheme %s\n" - " opaque %s\n" - " authority %s\n" - " server %s\n" - " user %s\n" - " port %d\n" - " path %s\n", - name, - uri->scheme, uri->opaque, uri->authority, uri->server, - uri->user, uri->port, uri->path); + DEBUG("libvirt: do_open: name \"%s\" to URI components:\n" + " scheme %s\n" + " opaque %s\n" + " authority %s\n" + " server %s\n" + " user %s\n" + " port %d\n" + " path %s\n", + name, + uri->scheme, uri->opaque, uri->authority, uri->server, + uri->user, uri->port, uri->path); #endif ret->name = strdup (name); @@ -565,16 +575,16 @@ do_open (const char *name, for (i = 0; i < virDriverTabCount; i++) { #ifdef ENABLE_DEBUG - fprintf (stderr, "libvirt: do_open: trying driver %d (%s) ...\n", - i, virDriverTab[i]->name); + DEBUG("libvirt: do_open: trying driver %d (%s) ...\n", + i, virDriverTab[i]->name); #endif res = virDriverTab[i]->open (ret, uri, auth, flags); #ifdef ENABLE_DEBUG - fprintf (stderr, "libvirt: do_open: driver %d %s returned %s\n", - i, virDriverTab[i]->name, - res == VIR_DRV_OPEN_SUCCESS ?

[Libvir] [PATCH] Update from gnulib.
by Jim Meyering 19 Jan '08

19 Jan '08

I ran ./bootstrap against a just-updated gnulib directory, so these changes now sync into libvirt all of the changes from gnulib since the last time: Update from gnulib. FYI, nearly all of these changes are also in the latest coreutils beta/test release, so if there are problems, I should hear about it soon. If you'd like to see justification for a particular change, you'll probably find it in a combination of these: gnulib's ChangeLog file a unit test change or addition, a message on the bug-gnulib mailing list.

Thanks for the review, Rich. Seeing that messed-up Subject: line, I realized that I sent a patch produced by "git-format-patch", forgetting that the ancient version of mailman behind this list would remove important parts of it.

[Libvir] handle PyTuple_New's malloc failure
by Jim Meyering 17 Jan '08

17 Jan '08

python/libvir.c calls PyTuple_New, but doesn't handle the possibility of a NULL return value. Subsequent use of the result pointer in e.g., PyTuple_SetItem, would dereference it. This fixes most of them, but leaves the ones in virConnectCredCallbackWrapper untouched. Fixing them properly is not as easy, and IMHO will require actual testing. In this patch, I combined each new test like this ((info = PyTuple_New(8)) == NULL) with the preceding "if (c_retval < 0)", since the bodies would be the same. Duplicating that 2-line body might look more readable, depending on which side of the bed you get up on... I can go either way.

by Dave Leskovec 17 Jan '08

17 Jan '08

Greetings, I'd like to extend libvirt to support Containers. As libvirt already supports Xen, KVM, QEMU and OpenVZ, I think it would be valuable to be able to utilize existing utilities to manage containers. I've spent some time looking through the libvirt api and how this Container support will fit. Based on the XML format section of the libvirt website and some list discussions I put together the following proposed XML format: <domain type='linuxcontainer'> <name>Container123</name> <uuid>8dfd44b31e76d8d335150a2d98211ea0</uuid> <container> <filesystem> <mount>/etc = /home/user/lxc_files/etc</mount> <mount>/var = /home/user/lxc_files/var</mount> </filesystem> <application>dbserver</application> <network hostname='browndog'> <ip address="192.168.1.110" netmask="255.255.255.0"/> <gateway address="192.168.1.1"/> <nameserver>192.168.1.1</nameserver> </ip> </network> <cpushare>40</cpushare> <memory>65536</memory> </container> <devices> <console tty='/dev/pts/4' /> </devices> </domain> The clone() function is used with the CLONE_NEWPID and CLONE_NEWNS flags to start a new process within it's own process name space. The only processes visible to it will be itself and any processes that it spawns. The process that clone creates will start out preparing the container environment. This involves setting up any network interface, setting up the file system by performing any requested mounts, mounting /proc, setting up a tty device, populating /dev as necessary, and performing any other necessary initializations. It will then start the application(s) requested by the user. The executables started within the container could be an application or script or possibly /sbin/init. The mounts that the user specifies will need to be populated with the appropriate contents for whatever applications they are going to run within the container. cgroup will be used for isolation and association with controllers for cpu and memory resources. I'm planning to start in on defining a container. All comments and questions are welcome. Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

Yes, thats me who took Linux Container XML for OpenVZ XML. I better ask Shuveb. Hi, Shuveb, there is a whole bunch of questions! > Quota is not implemented as yet. As quota is not implemented yet i want to ask - what is the meaning of it? Is it analog of diskspace and diskinodes? And what does <gateway> sets?

[Libvir] [PATCH] Linux-VServer support
by Daniel Hokka Zakrisson 15 Jan '08

15 Jan '08

This patch implements support for Linux-VServer guests. It is currently missing vcpu and console support, and the necessary virsh code to support it, but is otherwise pretty feature complete. This is an XML dump from one of my guests: <domain type='vserver' id='40010'> <name>lenny</name> <uuid>19e12957-261a-5a06-d6d0-89917d6d439f</uuid> <memory>2048000</memory> <os> <hostname>lenny.test</hostname> <type arch='i686'>vserver</type> </os> <devices> <interface type='ethernet'> <ip prefix='24' interface='dummy0' address='192.168.20.4' /> </interface> <interface type='ethernet'> <ip prefix='24' interface='dummy0' type='range' address='192.168.32.100' address2='192.168.32.200'/> </interface> <disk type='directory' device='directory'> <source directory='/vservers/lenny' type='auto' options='defaults'/> <target directory='/'/> </disk> <disk type='directory' device='directory'> <source directory='/srv' type='ext3' options='bind,ro'/> <target directory='/srv'/> </disk> <disk type='block' device='directory'> <source dev='/dev/mapper/test' type='ext3' options='defaults'/> <target directory='/mnt'/> </disk> </devices> </domain> -- Daniel Hokka Zakrisson

[Libvir] PATCH: Fix remote driver SSH tunnelling
by Daniel P. Berrange 15 Jan '08

15 Jan '08

An off-by-one error in the remote driver checking for malloc() failure in the SSH argv meant all SSH connections were always rejected. It was always checking the trailing NULL in the argv[] Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] [PATCH] Keyboard layout support for QEMU/KVM
by Daniel Hokka Zakrisson 15 Jan '08

15 Jan '08

This patch adds support for qemu's -k option, which is required to run virt-manager with a non-US keymap. Without it, keys are remapped a number of times, ending up with a completely unusable layout. Even with this patch I am having problems using the AltGr key, returning a scancode of 00. This seems to be a qemu problem though. -- Daniel Hokka Zakrisson

[Libvir] RFC: Add a short doc with libvirt coding style guidelines
by Daniel P. Berrange 15 Jan '08

15 Jan '08

There's a few coding style guidelines we've kind of informally agreed upon wrt to libvirt patches, and perhaps more that we ought to make decisions on. For the benefit of people sending patches I reckon its worth writing these down. So I'm attaching a proposed doc 'HACKING' in which we can detail the guidelines. And yes, we don't uniformly comply with these guidelines in all places....all the more reason to list them & fix cases where we don't comply :-) Thoughts.. ?

[Libvir] RFC: PATCH 0/5: asynchronous background jobs
by Daniel P. Berrange 14 Jan '08

14 Jan '08

We currently have a restriction that virConnectPtr objects must only be used by a single thread. At the same time we have a number of operations that can take a very long time. This means that applications are pretty much forced to use multi-threading if they want to continue to respond to user input, and thus are also forced to use multiple virConnectPtr objects. This is sub-optimal because opening multiple virConnectPtr objects may well result in the user being prompted for auth credentials multiple times. It also doesn't provide any way of providing progess information on the long running jobs, nor a way to cancel them. Thus the following series of patches introduces the concept of an 'asynchronous background job', represented by a virJobPtr object in the libvirt public API. A job has an elapsed time, and may optionally include an estimated time of completion. If it is a job with a bounded amount of work, it will also have a percentage completion counter. There is the ability to request cancellation of an in progress job, and fetch any error associated with a completed job. The primary reason I implemented this support, is that the storage APIs will make the current situation untennable. Allocating storage can take a seriously long time (many many minutes if cloning multi-GB files). This absolutely requires progress information and an ability to cancel an operation. There are a number of existing APIs which can benefit from this, hence I decided to work on this separately from the main storage APIs. The APIs which can make use of this are virDomainCreateLinux, virDomainCreate, virNetworkCreate, virNetworkCreateXML, virDomainSave, virDomainRestore, and virDomainDumpCore. For all of these we add a second variant postfixed with 'Job' in the name, returning a virJobPtr object This work isn't finished, but I wanted to put these patches out for comment before going further. In particular I need to figure out how to hook this up to the remote driver and daemon, and deal with a few lifecycle issues. eg what todo if a virConnectPtr object is released while a background job is active. With all 5 patches applied you should be able to run the following test case: virsh --connect test:///default save --verbose test foo No other drivers / commands are hooked up aside from 'save' in the 'test' driver.
