Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.
* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
* m4/compiler-flags.m4: Obsoleted by gl_WARN_ADD
* src/Makefile.am src/libvirt_private.syms configure.ac: share and
reuse the sexpr routines from sexpr.h of the old xen driver
* src/libxl/libxl_driver.c: implements libxlDomainXMLFromNative and
libxlDomainXMLToNative
The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.
Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.
The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.
Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.
* configure.ac: Remove probe for xmlrpc & --with-one arg
* daemon/Makefile.am, daemon/libvirtd.c, src/Makefile.am: Remove

The libxenlight driver does not build against the tech preview
version of libxenlight in Xen 4.0. Only enable building the
driver against more complete libxenlight found in Xen 4.1.
Add a new xen driver based on libxenlight [1], which is the primary
toolstack starting with Xen 4.1.0. The driver is stateful and runs
privileged only.
Like the existing xen-unified driver, the libxenlight driver is
accessed with xen:// URI. Driver selection is based on the status
of xend. If xend is running, the libxenlight driver will not load
and xen:// connections are handled by xen-unified. If xend is not
running *and* the libxenlight driver is available, xen://
connections are deferred to the libxenlight driver.
V6:
- Address several code style issues noted by Daniel Veillard
- Make drive work with xen:/// URI
- Hold domain object reference while domain is injected in
libvirt event loop. Race found and fixed by Markus Groß.
V5:
- Ensure events are unregistered when domain private data
is destroyed. Discovered and fixed by Markus Groß.
V4:
- Handle restart of libvirtd, reconnecting to previously
started domains
- Rebased to current master
- Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)
V3:
- Reserve vnc port within driver when autoport=yes
V2:
- Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81)
- Rebased to current master
- Plug memory leaks found by Stefano Stabellini and valgrind
- Handle SHUTDOWN_crash domain death event

The kill() function doesn't exist on Win32, so it needs to be
checked for at build time & code disabled in cgroups
* configure.ac: Check for kill()
* src/util/cgroup.c: Stub out virCGroupKill* functions
when kill() isn't available
Currently, we need virIsDevMapperDevice() when we build libvirt with
disk or mpath storage drivers. So we should check device-mapper-devel
when we build with disk storage driver but without mpath storage
driver.
Two regressions:
Commit df1011ca broke builds for systems that lack devmapper
(non-Linux, as well as Linux with ./autogen.sh --without-libvirtd
and without the libraries present).
Commit ce6fd650 broke cross-compilation, due to a gnulib bug.
* .gnulib: Update to latest, for cross-compilation fix.
* src/util/util.c (virIsDevMapperDevice): Provide stub for
platforms not using storage driver.
* configure.ac (devmapper): Arrange to define HAVE_LIBDEVMAPPER_H.
devmapper issue reported by Wen Congyang.
The name convention of device mapper disk is different, and 'parted'
can't be used to delete a device mapper disk partition. e.g.

Error: Expecting a partition number.
This patch introduces 'dmsetup' to fix it.
Changes:
- New function "virIsDevMapperDevice" in "src/utils/utils.c"
- remove "is_dm_device" in "src/storage/parthelper.c", use
"virIsDevMapperDevice" instead.
- Requires "device-mapper" for 'with-storage-disk" in "libvirt.spec.in"

- Changes on "src/Makefile.am" to link against libdevmapper
- New entry for "virIsDevMapperDevice" in "src/libvirt_private.syms"
Changes from v1 to v3:
- s/virIsDeviceMapperDevice/virIsDevMapperDevice/g
- replace "virRun" with "virCommand"
- sort the list of util functions in "libvirt_private.syms"
- ATTRIBUTE_NONNULL(1) for virIsDevMapperDevice declaration.

Make with_packager and with_packager_version default to "no". This way
--without-packager-version (as shorthand for --with-packager(-version)=no)
works correctly too.
Prior to this patch libvirt outputs a line like this when
--with-packager(-version) was not specified
# ./daemon/libvirtd
14:11:15.018: 31796: info : libvirt version: 0.8.8, package: ()
Now the unspecified parts are correctly omitted.
Reported by Osier Yang.
The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.
eg
$ LIBVIRT_DEBUG=1 virsh
18:13:28.013: 17536: info : libvirt version: 0.8.7
18:13:28.013: 17536: debug : virInitialize:361 : register drivers
...
The 'configure' script gains two new arguments which can be
used as
--with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
--with-packager-version="1.fc14"
to allow distros to append a custom string with package specific
data.
The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.
eg
$ LIBVIRT_DEBUG=1 virsh
18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
18:14:52.086: 17551: debug : virInitialize:361 : register drivers
Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds
* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-packager & --with-packager-version args
* .gnulib: Update to latest, for sigpipe and sigaction modules.
* bootstrap.conf (gnulib_modules): Add siaction, sigpipe, strerror_r.
* tools/virsh.c (vshSetupSignals) [!SIGPIPE]: Delete, now that
gnulib guarantees it.
(SA_SIGINFO): Define for mingw fallback.
* src/util/virterror.c (virStrerror): Simplify, now that gnulib
guarantees the POSIX interface.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop redundant check.
(AM_PROG_CC_STDC): Move earlier, to keep autoconf happy.
virSetUIDGID() sets both the real and effective group and user of the
process, and additionally calls initgroups() to assure that the
process joins all the auxiliary groups that the given uid is a member
of.
Running an instance of the router advertisement daemon (radvd) allows
guests using the virtual network to automatically acquire an IPv6
address and default route. Note that acquiring an address only works
for networks with a prefix length of exactly 64 - radvd is still run
in other circumstances, and still advertises routes, but autoconf will
not work because it requires exactly 64 bits of address info from the
network prefix.
This patch avoids a race condition with the pidfile by manually
daemonizing radvd rather than allowing it to daemonize itself, then
creating our own pidfile (in addition to radvd's own file, which is
unnecessary, but there is no way to tell radvd to not create it). This
is accomplished by exec'ing it with "--debug 1" in the commandline,
and using virCommand's features to fork, create a pidfile, and detach
from the newly forked process.
All of the iptables functions eventually call down to a single
bottom-level function, and fortunately, ip6tables syntax (for all the
args that we use) is identical to iptables format (except the
addresses), so all we need to do is:
1) Get an address family down to the lowest level function in each
case, either implied through an address, or explicitly when no
address is in the parameter list, and
2) At the lowest level, just decide whether to call "iptables" or
"ip6tables" based on the family.
The location of the ip6tables binary is determined at build time by
autoconf. If a particular target system happens to not have ip6tables
installed, any attempts to run it will generate an error, but that
won't happen unless someone tries to define an IPv6 address for a
network. This is identical behavior to IPv4 addresses and iptables.
brSetInetAddress can only set a single IP address on the bridge, and
uses a method (ioctl(SIOCSETIFADDR)) that only works for IPv4. Replace
it and brSetInetNetmask with a single function that uses the external
"ip addr add" command to add an address/prefix to the interface - this
supports IPv6, and allows adding multiple addresses to the interface.
Although it isn't currently used in the code, we also add a
brDelInetAddress for completeness' sake.
Also, while we're modifying bridge.c, we change brSetForwardDelay and
brSetEnableSTP to use the new virCommand API rather than the
deprecated virRun, and also log an error message in bridge_driver.c if
either of those fail (previously the failure would be completely
silent).
Now the VMware driver doesn't depend on the ESX driver anymore.
Add a WITH_VMX option that depends on WITH_ESX and WITH_VMWARE.
Also add a libvirt_vmx.syms file.
Move some escaping functions from esx_util.c to vmx.c.
Adapt the test suite, ESX and VMware driver to the new code layout.
* configure.ac (dlopen): Cygwin dlopen is in libc; avoid spurious
failure.
(XDR_CFLAGS): Define when needed.
* src/Makefile.am (libvirt_driver_remote_la_CFLAGS): Use it.
* configure.ac (with_selinux): Check for <selinux/label.h>.
* src/security/security_selinux.c (getContext): New function.
(SELinuxRestoreSecurityFileLabel): Use it to restore compilation
when using older libselinux.
Autoconf 2.59 doesn't define ${localedir}, so libvirt was failing
to compile due to a missing LOCALEDIR until today's configmake fix.
* .gnulib: Update to latest for configmake fix.
* configure.ac (libpcap): Avoid AS_CASE.
Don't require dlopen, but link to ole32 and oleaut32 on Windows.
Don't expose g_pVBoxFuncs anymore. It was only used to get the
version of the API. Make VBoxCGlueInit return the version instead.
This simplifies the implementation of the MSCOM glue layer.
Get the VirtualBox version from the registry.
Add a dummy implementation of the nsIEventQueue to the MSCOM glue
as there seems to be no direct equivalent with MSCOM. It might be
implemented using the normal window message loop. This requires
additional investigation.
Without this fix, ./configure --with-libpcap will cause --with-libpcap=yes
to be implicitly passed down, which cause yes/bin/pcap-config to be
searched for rather than /usr/bin/pcap-config.
Also output pcap: no when pcap is not found or disabled.
This fixes a misleading error message saying the libnl package
needs to be installed, when it's really the libnl-devel package
needing to be installed.
To allow messages from different threads to be untangled,
include an integer thread identifier in log messages.
* src/util/logging.c: Include thread ID
* src/util/threads.h, src/util/threads.h, src/util/threads-pthread.c:
Add new virThreadSelfID() function
* configure.ac: Check for sys/syscall.h
To avoid the need for duplicating implementations of virStream
drivers, provide a generic implementation that can handle any
FD based stream. This code is copied from the existing impl
in the QEMU driver, with the locking moved into the stream
impl, and addition of a read callback
The FD stream code will refuse to operate on regular files or
block devices, since those can't report EAGAIN properly when
they would block on I/O
* include/libvirt/virterror.h, include/libvirt/virterror.h: Add
VIR_FROM_STREAM error domain
* src/qemu/qemu_driver.c: Remove code obsoleted by the new
generic streams driver.
* src/fdstream.h, src/fdstream.c, src/fdstream.c,
src/libvirt_private.syms: Generic reusable FD based streams
This partly reverts df90ca7661.
Don't disable the VirtualBox driver when configure can't find
VBoxXPCOMC.so, rely on detection at runtime again instead.
Keep --with-vbox=/path/to/virtualbox intact, added to for:
https://bugzilla.redhat.com/show_bug.cgi?id=609185
Detection order for VBoxXPCOMC.so:
1. VBOX_APP_HOME environment variable
2. configure provided location
3. hardcoded list of known locations
4. dynamic linker search path
Also cleanup the glue code and improve error reporting.
A missing shell was noisy, and the use of command to decipher a
shell's absolute path requires "" rather than ''.
* configure.ac (lv_cv_wrapper_shell): Fix logic errors if candidate
shell is not available.
* .gitignore: Ignore file created when /bin/sh is old dash.
Reported by Matthias Bolte.
Older dash mistakenly truncates regular files when using <> redirection;
this kills our use of double dd to reduce storage overhead when
saving qemu images. But qemu insists on running a command through
/bin/sh, so we work around it by having qemu run $sh -c 'real command'
when we have a replacement $sh in mind.
* configure.ac (VIR_WRAPPER_SHELL): Define to a replacement shell,
if /bin/sh is broken on <> redirection.
* src/qemu/qemu_monitor.h (VIR_WRAPPER_SHELL_PREFIX)
(VIR_WRAPPER_SHELL_SUFFIX): New macros.
* src/qemu/qemu_monitor_text.c (qemuMonitorTextMigrateToFile): Use
them.
* src/qemu/qemu_monitor_json.c (qemuMonitorJSONMigrateToFile):
Likewise.
The default location for the XML catalog file, /etc/xml/catalog,
used when validating the generated html docs, isn't correct for
MacOS X.
This commit adds an option to the configure script, allowing the
default to be overridden:
--with-xml-catalog-file=/path/to/xml/catalog/file
It is useful to know where the client is connecting from,
so include the socket address in probe data.
* daemon/libvirtd.h: Use virSocketAddr for storing client
address and keep printable address handy for logging
* daemon/libvirtd.c: Include socket address in client
connect/disconnect probes
* daemon/probes.d: Add socket address to probes
* examples/systemtap/client.stp: Print socket address
* src/util/network.h: Add sockaddr_un to virSocketAddr union
Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).
# stap examples/systemtap/client.stp
Client fd=44 connected readonly=0
Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.
* Makefile.am: Add examples/systemtap subdir
* autobuild.sh: Disable dtrace for mingw32
* configure.ac: Add check for dtrace
* daemon/.gitignore: Ignore generated dtrace probe file
* daemon/Makefile.am: Build dtrace probe header & object
files
* daemon/libvirtd.stp: SystemTAP convenience probeset
* daemon/libvirtd.c: Add connect/disconnect & TLS probes
* daemon/remote.c: Add SASL and PolicyKit auth probes
* daemon/probes.d: Master probe definition
* daemon/libvirtd.h: Add convenience macro for probes
so that compilation is a no-op when dtrace is not available
* examples/systemtap/Makefile.am, examples/systemtap/client.stp
Example systemtap script using dtrace probe markers
* libvirt.spec.in: Enable dtrace on F13/RHEL6
* mingw32-libvirt.spec.in: Force disable dtrace
Integrate with libaudit.so for auditing of important operations.
libvirtd gains a couple of config entries for auditing. By
default it will enable auditing, if its enabled on the host.
It can be configured to force exit if auditing is disabled
on the host. It will can also send audit messages via libvirt
internal logging API
Places requiring audit reporting can use the VIR_AUDIT
macro to report data. This is a no-op unless auditing is
enabled
* autobuild.sh, mingw32-libvirt.spec.in: Disable audit
on mingw
* configure.ac: Add check for libaudit
* daemon/libvirtd.aug, daemon/libvirtd.conf,
daemon/test_libvirtd.aug, daemon/libvirtd.c: Add config
options to enable auditing
* include/libvirt/virterror.h, src/util/virterror.c: Add
VIR_FROM_AUDIT source
* libvirt.spec.in: Enable audit
* src/util/virtaudit.h, src/util/virtaudit.c: Simple internal
API for auditing messages
* .gnulib: Update to latest, for termios fix.
* configure.ac (AC_CHECK_HEADERS): Drop redundent check.
* bootstrap: Synchronize from upstream.
Reported by Daniel P. Berrange.
Disabling these two drivers on MacOS X, where they are known to
not work, allows libvirt (including the daemon) to compile without
any further changes.
This fixes a small logic bug, where passing --without-macvtap
on the configure line, or otherwise indicating a lack of
support for macvtap, causes configure to bail.
The configure script was breaking on MacOS X unless passed:
--without-storage-mpath
This patch leverages Stefan Bergers earlier work for nwfilter,
so non-linux systems don't even attempt to build multipath.
In this patch I am reworking the logic around detecting virtual port support and requiring the libnl dependency.
- It requires --with-macvtap and displays an error in case of --without-macvtap --with-virtualport.
- It tests for availability of certain data in include files and displays an error in case the include file is not at the correct level and --with-virtualport was chosen
- displays 'checking' messages for macvtap and virtualport support and results
- libnl support is required when macvtap is found or requested; if libnl is not there, please supply without-macvtap
Mac OS X provides an "/Applications" folder, not an "/Application" folder,
so installed VirtualBox wasn't being detected by default.
This 1 character patch fixes this.
I got tired of seeing this.
config.status: executing libtool commands
/bin/rm: cannot remove `libtoolT': No such file or directory
config.status: executing po-directories commands
While I was at it, there were a couple other unused variables.
* configure.ac (RM, MV, TAR): Drop; nothing in libvirt directly uses
this, and assigning RM interferes with libtool.
'./autobuild.sh' with lcov installed discovered that our
coverage support has been bit-rotting for a while. This
restores it back to a successful state, although I have
not yet spent any time looking through the resulting files to
look for low-hanging fruit in the unit test coverage front.
* configure.ac: Clear COMPILER_FLAGS at right place.
* Makefile.am (cov): Newer genhtml no longer likes plain -s.
* m4/compiler-flags.m4 (gl_COMPILER_FLAGS): Don't AC_SUBST
COMPILER_FLAGS; it is a shell variable for use in configure only.
* src/Makefile.am (AM_CFLAGS, AM_LDFLAGS): New variables, to make
it easier to provide global flag additions. Use throughout, to
uniformly apply coverage flags.
* .gitignore: Globally ignore gcov output.
* daemon/.gitignore: Simplify.
* src/.gitignore: Likewise.
* tests/.gitignore: Likewise.
This would have detected the bug in commit 38ad33931 (Aug 09), which
we missed until commit f828ca35 (Jul 10); over 11 months later.
However, on Fedora 13, it also triggers LOTS of warnings from
the libcurl-devel header for two files:

esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]

xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op]
...
libcurl allows to disable the type-checking code that triggers those
warnings, along with the reduction in type-safety of calls to some
libcurl functions. I figure this is worth the improved compiler
checking throughout the rest of libvirt.
* acinclude.m4 (--enable-compile-warnings=error): Add -Wlogical-op.
* configure.ac: Add -DCURL_DISABLE_TYPECHECK to LIBCURL_CFLAGS to
avoid compilation warning.

After the recent libvirt-qemu library addition, VPATH builds fail with:

CCLD libvirt-qmeu.la
/usr/bin/ld: cannot open linker script file libvirt_qemu.syms: No such file or directory
This fixes both issues (there are still some documentation VPATH issues,
but those don't show up with 'make check').
* configure.ac (LIBVIRT_QEMU_SYMBOL_FILE): While libvirt.syms is
generated and lives in $(builddir), libvirt_qemu.syms is static
and lives in $(srcdir).
* include/libvirt/libvirt-qemu.h (includes): Pull in libvirt.h via
the public location, since this is a public header.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point. Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.
Changes since v1:
- Go back to using the virDriver table for qemuDomainMonitorCommand, due to
linking issues
- Added versioning information to the libvirt-qemu.so
Changes since v2:
- None
Changes since v3:
- Add LGPL header to libvirt-qemu.c
- Make virLibConnError and virLibDomainError macros instead of function calls
Changes since v4:
- Move exported symbols to libvirt_qemu.syms

This allows the user to give an explicit path to configure
./configure --with-vbox=/path/to/virtualbox
instead of having the VirtualBox driver probe a set of possible
paths at runtime. If no explicit path is specified then configure
probes the set of "known" paths.

This patch that adds support for configuring 802.1Qbg and 802.1Qbh
switches. The 802.1Qbh part has been successfully tested with real
hardware. The 802.1Qbg part has only been tested with a (dummy)
server that 'behaves' similarly to how we expect lldpad to 'behave'.
The following changes were made during the development of this patch:
- Merging Scott's v13-pre1 patch
- Fixing endptr related bug while using virStrToLong_ui() pointed out
by Jim Meyering
- Addressing Jim Meyering's comments to v11
- requiring mac address to the vpDisassociateProfileId() function to
pass it further to the 802.1Qbg disassociate part (802.1Qbh untouched)
- determining pid of lldpad daemon by reading it from /var/run/libvirt.pid
(hardcode as is hardcode alson in lldpad sources)
- merging netlink send code for kernel target and user space target
(lldpad) using one function nlComm() to send the messages
- adding a select() after the sending and before the reading of the
netlink response in case lldpad doesn't respond and so we don't hang
- when reading the port status, in case of 802.1Qbg, no status may be
received while things are 'in progress' and only at the end a status
will be there.
- when reading the port status, use the given instanceId and vf to pick
the right IFLA_VF_PORT among those nested under IFLA_VF_PORTS.
- never sending nor parsing IFLA_PORT_SELF type of messages in the
802.1Qbg case
- iterating over the elements in a IFLA_VF_PORTS to pick the right
IFLA_VF_PORT by either IFLA_PORT_PROFILE and given profileId
(802.1Qbh) or IFLA_PORT_INSTANCE_UUID and given instanceId (802.1Qbg)
and reading the current status in IFLA_PORT_RESPONSE.
- recycling a previous patch that adds functionality to interface.c to
- get the vlan identifier on an interface
- get the flags of an interface and some convenience function to
check whether an interface is 'up' or not (not currently used here)
- adding function to determine the root physical interface of an
interface. For example if a macvtap is linked to eth0.100, it will
find eth0. Also adding a function that finds the vlan on the 'way to
the root physical interface'
- conveying the root physical interface name and index in case of 802.1Qbg
- conveying mac address of macvlan device and vlan identifier in
IFLA_VFINFO_LIST[ IFLA_VF_INFO[ IFLA_VF_MAC(mac), IFLA_VF_VLAN(vlan) ] ]
to (future) lldpad via netlink
- To enable build with --without-macvtap rename the
[dis|]associatePortProfileId functions, prepend 'vp' before their
name and make them non-static functions.
- Renaming variable multicast to nltarget_kernel and inverting
the logic
- Addressing Jim Meyering's comments; this also touches existing
code for example for correcting indentation of break statements or
simplification of switch statements.
- Renamed occurrencvirVirtualPortProfileDef to virVirtualPortProfileParamses
- 802.1Qbg part prepared for sending a RTM_SETLINK and getting
processing status back plus a subsequent RTM_GETLINK to
get IFLA_PORT_RESPONSE.
Note: This interface for 802.1Qbg may still change
- [David Allan] move getPhysfn inside IFLA_VF_PORT_MAX to avoid
compiler
warning when latest if_link.h isn't available
- move from Stefan's 802.1Qb{g|h} XML v8 to v9
- move hostuuid and vf index calcs to inside doPortProfileOp8021Qbh
- remove debug fprintfs
- use virGetHostUUID (thanks Stefan!)
- fix compile issue when latest if_link.h isn't available
- change poll timeout to 10s, at 1/8 intervals
- if polling times out, log msg and return -ETIMEDOUT
- Add Stefan's code for getPortProfileStatus
- Poll for up to 2 secs for port-profile status, at 1/8 sec intervals:
- if status indicates error, abort openMacvtapTap
- if status indicates success, exit polling
- if status is "in-progress" after 2 secs of polling, exit
polling loop silently, without error
My patch finishes out the 802.1Qbh parts, which Stefan had mostly complete.
I've tested using the recent kernel updates for VF_PORT netlink msgs and
enic for Cisco's 10G Ethernet NIC. I tested many VMs, each with several
direct interfaces, each configured with a port-profile per the XML. VM-to-VM,
and VM-to-external work as expected. VM-to-VM on same host (using same NIC)
works same as VM-to-VM where VMs are on diff hosts. I'm able to change
settings on the port-profile while the VM is running to change the virtual
port behaviour. For example, adjusting a QoS setting like rate limit. All
VMs with interfaces using that port-profile immediatly see the effect of the
change to the port-profile.
I don't have a SR-IOV device to test so source dev is a non-SR-IOV device,
but most of the code paths include support for specifing the source dev and
VF index. We'll need to complete this by discovering the PF given the VF
linkdev. Once we have the PF, we'll also have the VF index. All this info-
mation is available from sysfs.
This patch introduces a dependency on libnl, which subsequent patches
will then use.
Changes from V1 to V2:
- added diffstats
- following changes in tree
* configure.ac: Check for <linux/magic.h>.
* src/util/storage_file.c: Include <linux/magic.h> only if present.
Linux kernels prior to 2.6.19 lacked it.
[__linux__] (NFS_SUPER_MAGIC): Define if not already defined.
* configure.ac (AC_CHECK_FUNCS_ONCE, AC_SYS_LARGEFILE): Rely on
gnulib for strtok_r and large file support.
(AC_OBJEXT): Drop call now done by AC_PROG_CC.
(m4_foreach_w): Drop macro guaranteed by gnulib.
(AC_C_CONST): Drop call declared obsolete by autoconf.
Signed-off-by: Eric Blake <eblake@redhat.com>
Gnulib can guarantee that pthread.h exists, but for now, it is a dummy
header with no support for most pthread_* functions. Modify our
use of pthread to use function checks, rather than header checks,
to determine how much pthread support is present.
* bootstrap.conf (gnulib_modules): Add pthread.
* configure.ac: Drop all pthread.h checks. Optimize function
checks. Add check for pthread functions.
* src/Makefile.am (libvirt_lxc_LDADD): Ensure proper link.
* src/remote/remote_driver.c (remoteIOEventLoop): Depend on
pthread_sigmask, now that gnulib guarantees pthread.h.
* src/util/util.c (virFork): Likewise.
* src/util/threads.c (threads-pthread.c): Depend on
pthread_mutexattr_init, as a witness of full pthread support.
* src/util/threads.h (threads-pthread.h): Likewise.
When cross-compiling on Linux, configure will misdetect the target as
Linux because it uses uname instead of relying on the $host variable.
This results in including libvirt_linux.syms into libvirt.syms and
therefore trying to export undefined symbols.
Replace uname checks with $host checks to fix this.
In commit 98fb83ce25 I changed the
version script handling. But it seems that I didn't test this properly
and broke it. The .def file is passed to the compiler directly, but it
should get passed to the linker instead.
Set VERSION_SCRIPT_FLAGS to -Wl, to pass the .def file correctly to
the linker.
This fixes the undefined symbol errors while linking virsh.
Let configure detect ld instead of hardcoding /usr/bin/ld, because
MinGW may have ld in /bin.
Only use a .def file to export symbols on MinGW. Cygwin's ld supports
the normal .syms file used on Linux.
Cygwin's XDR implementation defines xdr_u_int64_t instead of
xdr_uint64_t and lacks IXDR_PUT_INT32/IXDR_GET_INT32.
Alter the IXDR_GET_LONG regex in rpcgen_fix.pl so it doesn't destroy
the #define IXDR_GET_INT32 IXDR_GET_LONG in remote_protocol.x.
Also fix the remote_protocol.h regex in rpcgen_fix.pl.
Also move the equivalent checks for LXC and UML before their header
checks. This way configure doesn't check for the headers when the driver
gets disabled anyway.
Under cygwin, winsock2.h is intentionally incompatible with,
<sys/socket.h>, and checking for existence is wrong.
Under mingw, HAVE_WINSOCK2_H is defined on our behalf by
gnulib, in a way that does not interfere with cygwin.
* configure.ac: Drop unnecessary header check.
Reported by Matthias Bolte.
* Fix a logic error in configure.ac that prevented --with-selinux=no
from being used with --with-secdriver-selinux=no.
* Fix some strings to clarify the difference between --with-selinux
and --with-secdriver-selinux.

* configure.ac (STATIC_ANALYSIS): Define when run via clang's
scan-build or coverity-prevent's cov-build.
Use the CLANG_CC and COVERITY_BUILD_COMMAND envvars as witnesses.
I am getting rid of determining the path to necessary CLI tools at
compile time. Instead, now the firewall driver has an initialization
function that uses virFindFileInPath() to determine the path to
necessary CLI tools and a shutdown function to free allocated memory.
The rest of the patch mostly deals with availability of the CLI tools
and to not call certain code blocks if a tool is not available and that
strings now have to be built slightly differently.
* configure.ac docs/news.html.in libvirt.spec.in src/libvirt_public.syms:
updates for release of 0.8.0
* po/*.po po/libvirt.pot: updated a lar set of localizations, and merge
the messages
The network filter / snapshot / hooks code introduced some
non-portable pices that broke the win32 build
* configure.ac: Check for net/ethernet.h required by nwfile config
parsing code
* src/conf/nwfilter_conf.c: Define ethernet protocol constants
if net/ethernet.h is missing
* src/util/hooks.c: Disable hooks build on Win32 since it lacks
fork/exec/pipe
* src/util/threads-win32.c: Fix unchecked return value
* tools/virsh.c: Disable SIGPIPE on Win32 since it doesn't exist.
Fix non-portable strftime() formats
Just checking for a windres tool might hit even on Linux systems when
building for Linux (e.g.: when using Gentoo and having built binutils
with multitarget support), and will then fail to link properly at the
end of the build.
* configure.ac: Avoid searching for windres on non windows target
