[libvirt] [PATCH] maint: avoid potential promotion issues with [ug]id_t
by Eric Blake 08 Jan '13

08 Jan '13

POSIX does not guarantee whether uid_t and gid_t are signed or unsigned, nor does it guarantee whether they are smaller, same size, or larger than int (or even the same size as one another). Therefore, it is possible to have platforms where '(uid_t)-1==-1' is false or where 'uid = gid = -1' sets uid to the wrong value, thanks to integer promotion rules. The only portable way to use the placeholder value of these two types is to always use a cast. Thankfully, the issue is mostly theoretical - sanlock only compiles on Linux for now, and on Linux, these types do not suffer from strange promotion problems. * src/locking/lock_driver_sanlock.c (virLockManagerSanlockSetupLockspace, virLockManagerSanlockInit) (virLockManagerSanlockCreateLease): Cast -1 to proper type before comparing with uid_t or gid_t. --- src/locking/lock_driver_sanlock.c | 17 +++++++++-------- 1 file changed, 9 insertions(+), 8 deletions(-) diff --git a/src/locking/lock_driver_sanlock.c b/src/locking/lock_driver_sanlock.c index c955003..d06fa66 100644 --- a/src/locking/lock_driver_sanlock.c +++ b/src/locking/lock_driver_sanlock.c @@ -1,7 +1,7 @@ /* * lock_driver_sanlock.c: A lock driver for Sanlock * - * Copyright (C) 2010-2012 Red Hat, Inc. + * Copyright (C) 2010-2013 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 @@ -236,7 +236,7 @@ static int virLockManagerSanlockSetupLockspace(void) goto error; } - if (driver->group != -1) + if (driver->group != (gid_t) -1) perms |= 0060; if ((fd = open(path, O_WRONLY|O_CREAT|O_EXCL, perms)) < 0) { @@ -249,7 +249,7 @@ static int virLockManagerSanlockSetupLockspace(void) VIR_DEBUG("Someone else just created lockspace %s", path); } else { /* chown() the path to make sure sanlock can access it */ - if ((driver->user != -1 || driver->group != -1) && + if ((driver->user != (uid_t) -1 || driver->group != (gid_t) -1) && (fchown(fd, driver->user, driver->group) < 0)) { virReportSystemError(errno, _("cannot chown '%s' to (%u, %u)"), @@ -303,8 +303,8 @@ static int virLockManagerSanlockSetupLockspace(void) } } else if (S_ISREG(st.st_mode)) { /* okay, the lease file exists.

[libvirt] [PATCHv4 0/2] S390: Adding support for SCLP Console
by Viktor Mihajlovski 08 Jan '13

08 Jan '13

The S390 architecture comes with a native console type (SCLP console) which is now also supported by current QEMU. This series is enabling libvirt to configure S390 domains with SCLP consoles. The domain XML has to be extended for the new console target types 'sclp' and 'sclplm' (line mode = dumb). As usual the QEMU driver must do capability probing in order to find out whether SCLP is supported and format the QEMU command line for the new console type. V2/V3 Changes: Rebased to current master, resolving conflicts. V4 Changes: Rebased, changed 'since' to 1.0.2 in formatdomain.html.in J.B.

Re: [libvirt] Memory free in libvirt JNA
by Benjamin Wang (gendwang) 08 Jan '13

08 Jan '13

Hi, I wrote a code to verify the memory leak problem as following. C code in so: void checkJNAMemLeak1(int **head, int *length) { long i = 0; *head = (int *)malloc(sizeof(int) * 100000000); for(i=0; i<100000000; i++) { (*head)[i] = 1; } *length = 100000000; } Java code: public static void testJNAMemLeak1() { PointerByReference head = new PointerByReference(); IntByReference length = new IntByReference(); while(true) { libben.checkJNAMemLeak1(head, length); System.out.println(length.getValue()); sleep(1); } } When we check memory by top command, the virt and res will increase very quickly. When we check with jconsole, there is no memory in Java heap. Even I execute GC manually by jconsole. Nothing happen. If I change java code as following: public static void testJNAMemLeak1() { PointerByReference head = new PointerByReference(); IntByReference length = new IntByReference(); while(true) { libben.checkJNAMemLeak1(head, length); System.out.println(length.getValue()); sleep(1); libc.free(head.getValue()); } } public static void testJNAMemLeak1() { PointerByReference head = new PointerByReference(); IntByReference length = new IntByReference(); while(true) { libben.checkJNAMemLeak1(head, length); System.out.println(length.getValue()); sleep(1); libc.free(head.getValue()); } } Then everything works well. The virt and res will not increase. I think we must provide the free functions for all the memory allocated by libvirt. B.R.

Description1: If the native method returns char* and actually allocates memory, a return type of Pointer should be used to avoid leaking the memory. It is then up to you to take the necessary steps to free the allocated memory. 2. Description2: Declare the method as returning a Structure of the appropriate type, then invoke Structure.toArray(int) to convert to an array of initialized structures of the appropriate size. Note that your Structure class must have a no-args constructor, and you are responsible for freeing the returned memory if applicable in whatever way is appropriate for the called function. And the example code shows as following: // Original C code struct Display* get_displays(int* pcount); void free_displays(struct Display* displays); // Equivalent JNA mapping Display get_displays(IntByReference pcount); void free_displays(Display[] displays); ... IntByReference pcount = new IntByReference(); Display d = lib.get_displays(pcount); Display[] displays = (Display[])d.toArray(pcount.getValue()); ... lib.free_displays(displays); That's to say. All the memory allocated by native code must be freed explicitly in JNA part. We must add some free memory methods to support the memory-freeing. Any comments? B.R.

If this is mandatory, that's to say, we should a lot of methods into the current Libvirt-jna implementation to free the memory which is allocated by libvirt API. Please correct me! As far as I understat free() is aliased as finalize() on that object so the java runtime will call free() automatically on garbage collection. I'm not a java expert, check some Java litterature for more details about how this is done and the cases where free() might be better called directly.

[libvirt] [PATCH v2 0/2] add pci-bridge support
by liguang 08 Jan '13

Now, it's impossible to arrange devices into multi-pci-bus, for example: <sound model='ac97'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x1' slot='0x02' function='0x0'/> </video> libvirt will complain about "bus != 0", fortunately, qemu supports pci-to-pci bridge, if we want to use multi-pci-bus, we can define 2 pci bridge controllers, then attach 1 to the other as a subordinate pci-bus, so, 2 pci-buses appear. for example: <controller type='pci-bridge' index='0'/> <controller type='pci-bridge' index='1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' bridge='0'/> </controller> <sound model='ac97'> <address type='pci' domain='0x0000' bus='0x01' slot='0x02' function='0x0' bridge='1'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0' bridge='0'/> </video> src/conf/device_conf.c | 11 ++++++++++- src/conf/device_conf.h | 1 + src/conf/domain_conf.c | 5 ++++- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 25 ++++++++++++++++++++----- 5 files changed, 36 insertions(+), 7 deletions(-)

Based on a patch originally authored by Daniel De Graaf http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html This patch converts the Xen libxl driver to support only Xen >= 4.2.

[libvirt] [PATCH 0/3] add pci-bridge device and address type
by liguang 08 Jan '13

08 Jan '13

Now, it's unnecessary to arrange devices into multi-pci-bus, for example: <sound model='ac97'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x1' slot='0x02' function='0x0'/> </video> libvirt will complain about "bus != 0", fortunately, qemu supports pci-to-pci bridge, if we want to use multi-pci-bus, we can define 2 pci bridge devices then attach 1 to the other as a subordinate pci-bus, so, 2 pci-buses appear. for example: <pci-bridge type='root'/> <pci-bridge type='subordinate'> <address type='pci-bridge' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </pci-bridge> <sound model='ac97'> <address type='pci-bridge' domain='0x0000' bus='0x01' slot='0x02' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci-bridge' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> src/conf/domain_conf.c | 88 +++++++++++++++++++++++++++++++++++++++++++++--- src/conf/domain_conf.h | 22 ++++++++++++ src/qemu/qemu_command.c | 52 +++++++++++++++++++++++++++++++++++++++++++--- docs/formatdomain.html.in | 23 +++++++++++++++++++++++ 4 files changed, 176 insertions(+), 9 deletions(-)

[libvirt] libvirt-1.0.1 make check failure

Hello, I just attempted compilation and testing of libvirt-1.0.1 on an RHEL-6.3 x86_64 system and received one failure noted here: ... TEST: qemumonitorjsontest !!!!! 5 FAIL FAIL: qemumonitorjsontest ... ======================================= 1 of 68 tests failed (1 test was not run) Please report to libvir-list(a)redhat.com ======================================= The whole reason that I am even attempting this is because I have not be able to successfully craft a chroot LXC container using the older 0.9.10-21.el6_3.6 versions that I can get through yum. When attempting to start that container I get: # virsh start base error: Failed to start domain base error: internal error guest failed to start: 2013-01-07 18:48:31.382+0000: 2397: info : libvirt version: 0.9.10, package: 21.el6_3.6 (Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>, 2012-11-12-11:08:41, x86-008.build.bos.redhat.com) 2013-01-07 18:48:31.382+0000: 2397: error : lxcControllerRun:1484 : Failed to query file context on /lxc/base_rhel-6.3-i686: No data available The /lxc/base_rhel-6.3-i686 directory contains a basic installation of an i686 choot environment which I can interact fine with using chroot. I have not been able to figure out what "error : lxcControllerRun:1484 : Failed to query file context on /lxc/base_rhel-6.3-i686: No data available" is trying to tell me and was hoping that maybe a newer version of libvirt may be more friendly (though this is more likely coming from lxc code). Does anyone have suggestions? Thanks in advance. - Marc

[libvirt] [PATCH qom-cpu 00/11] disable-kvm_mmu + -cpu check/enforce fixes (v2)
by Eduardo Habkost 08 Jan '13

08 Jan '13

Changes on v2: - Now both the kvm_mmu-disable and -cpu "enforce" changes are on the same series - Coding style fixes Git tree for reference: git://github.com/ehabkost/qemu-hacks.git cpu-enforce-all.v2 https://github.com/ehabkost/qemu-hacks/tree/cpu-enforce-all.v2 Patches 1-2 disable the "kvm_mmu" feature by default on pc-1.4. Host-side support for the kvm_mmu feature was removed from the kernel since v3.3 (released in March 2012), it was marked for removal since January 2011 and it's slower than shadow or hardware assisted paging (see kernel commit fb92045843). It doesn't make sense to keep it enabled by default. Also, keeping it enabled by default would cause unnecessary hassle when libvirt start using the "enforce" option. Patches 3-11 change the -cpu check/enforce code to work as it should: it will check every single CPUID bit to make sure it is supported by the host. The changes are a bit intrusive, but: - The longer we take to make "enforce" strict as it should (and make libvirt finally use it), more users will have VMs with migration-unsafe unpredictable guest ABIs. For this reason, I would like to get this into QEMU 1.4. - The changes in this series should affect only users that are already using the "enforce" flag, and I believe whoever is using the "enforce" flag really want the strict behavior introduced by this series.

But as always, a careful review is appreciated :) Eric Blake (4): build: use common .in replacement mechanism build: properly substitute virtlockd.socket build: .service files don't need to be executable build: install libvirt sysctl file correctly daemon/Makefile.am | 49 +++++++++++++++++++++-------------------- libvirt.spec.in | 4 ++-- src/Makefile.am | 32 +++++++++++---------------- src/locking/virtlockd.init.in | 14 ++++++------ src/locking/virtlockd.socket.in | 2 +- tools/Makefile.am | 49 ++++++++++++++++++++--------------------- tools/virt-pki-validate.in | 2 +- tools/virt-sanlock-cleanup.in | 6 ++--- tools/virt-xml-validate.in | 2 +- 9 files changed, 77 insertions(+), 83 deletions(-) -- 1.8.0.2

[libvirt] [PATCH 0/6 v9] Unprivileged SG_IO support
by Osier Yang 07 Jan '13

07 Jan '13

As a result of RFC [1], this implements the unprivleged SG_IO support. 1/6 and 2/6 are already acked. v8 - v9: * Just rebasing. v7 - v8: * Change the XML tag name from "cdbfilter" to "sgio", and to leave enough room for future values, the values of "sgio" are "filtered" and "unfiltered" now. v6 - v7: * No restoring of unpriv_sgio per Daniel's thought. * Use "major:minor" as the hash key per Jirka's suggestion. Osier Yang (6): util: Prepare helpers for unpriv_sgio setting qemu: Add a hash table for the shared disks docs: Add docs and rng schema for new XML tag sgio conf: Parse and format the new XML qemu: set unpriv_sgio when starting domain and attaching disk qemu: Check if the shared disk's cdbfilter conflicts with others docs/formatdomain.html.in | 14 ++- docs/schemas/domaincommon.rng | 54 +++++--- src/conf/domain_conf.c | 55 ++++++-- src/conf/domain_conf.h | 10 ++ src/libvirt_private.syms | 4 + src/qemu/qemu_conf.c | 86 ++++++++++++ src/qemu/qemu_conf.h | 12 ++ src/qemu/qemu_driver.c | 30 ++++ src/qemu/qemu_process.c | 99 ++++++++++++++ src/qemu/qemu_process.h | 4 + src/util/virutil.c | 140 ++++++++++++++++++++ src/util/virutil.h | 13 ++ ...qemuxml2argv-disk-scsi-lun-passthrough-sgio.xml | 32 +++++ tests/qemuxml2xmltest.c | 1 + 14 files changed, 522 insertions(+), 32 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-lun-passthrough-sgio.xml [1] https://www.redhat.com/archives/libvir-list/2012-November/msg00988.html Regards, Osier

[libvirt] Setup libvirt deveplopment environment
by Thomas Lin 07 Jan '13

07 Jan '13

Hi, How to setup libvirt development environment on Ubuntu 12.04? I use virt-manager right now. It already installed virsh with it. I configured libvirt and it all went well. So how to test my modification in source code? When I open ./virsh from libvirt/tools/, it give errors like cannot open socket. Please help, I am a newbie. Thank you, Tom
