Add ebtables,iptables & iptables-ipv6 dependency to rpm.
Changes from V1 to V2:
-passing --without-libpcap to configure script, if libpcap is not to be used
Detected by clang. POSIX requires that the second argument to
va_start be the name of the last variable; and in some implementations,
passing *path instead of path would dereference bogus memory instead
of pulling arguments off the stack.
* src/util/util.c (virBuildPathInternal): Use correct argument to
va_start.
Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).
I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling. I also verified that the fix doesn't
affect normal migration with shared storage.
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.
This includes various things:
- fix the Requires: libvirt-client to use %{name} to allow easy
renaming
- when building ESX support one need libcurl-devel
- remove Makefile[.in] from xml/nwfilter in the docs, as this breaks
parallel install ation of i686 and x86_64 packages
- don't include nwfilter config files if not building with the daemon
all relatively trivial which is why I packed them together
* libvirt.spec.in: fix various small bugs
* docs/hacking.html.in: Use the "curly braces" section from coreutils'
HACKING, adapting for libvirt's different formatting style.
* HACKING: Sync from the above, still mostly manually.
Add an empty body for virCondWaitUntil and move virPipeReadUntilEOF
out of the '#ifndef WIN32' block, because it compiles fine with MinGW
in combination with gnulib.
Necessary on cygwin, where uid_t and gid_t are 4-byte long rather
than int, causing gcc -Wformat warnings.
* src/util/util.c (virFileOperationNoFork, virDirCreateNoFork)
(virFileOperation, virDirCreate, virGetUserEnt): Cast uid_t and
gid_t before passing to printf.
* .gitignore: Ignore Windows executables.
When a filter is updated, only those interfaces must have their old
rules cleared that either reference the filter directly or indirectly
through another filter. Remember between the different steps of the
instantiation of the filters which interfaces must be skipped. I am
using a hash map to remember the names of the interfaces and store a
bogus pointer to ~0 into it that need not be freed.
For the decision on whether to instantiate the rules, the check for a
pending IP address learn request is not sufficient since then only the
thread could instantiate the rules. So, a boolean needs to be passed
when the thread instantiates the filter rules late and the IP address
learn request is still pending in order to override the check for the
pending learn request. If the rules are to be updated while the thread
is active, this will not be done immediately but the thread will do that
later on.
WIN32 is always defined when __MINGW32__ is defined, but the
converse is not true. WIN32 is more generic, if someone were
to ever attempt porting to a microsoft compiler. This does
not affect Cygwin, which intentionally does not define WIN32.
* src/qemu/qemu_driver.c (qemuDomainGetBlockInfo): Use more
generic flag macro.
* src/storage/storage_backend.c
(virStorageBackendUpdateVolTargetInfoFD)
(virStorageBackendRunProgRegex): Likewise.
* tools/console.h (vshRunConsole): Likewise.
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.
This applies a fix to thos functions similar to that made to cmdEdit
in 270895063d, thus fnixing a memory
leak - if tmp is unlinked and NULLed early in the function, the memory
used by tmp is never freed. Since we will always unlink tmp prior to
freeing its memory at the end of the function, just remove the earlier
code and let cleanup: do the cleanup.
[Error message]
error: Failed to start domain lxc_test1
error: internal error Failed to create veth device pair: 512
The reason of the failure is that lxc driver unexpectedly re-uses
an auto-assigned veth name and tries to create the created veth
again. The failure will happen when a domain has multiple network
interfaces and the names of those are not specified in XML.
The patch fixes the problem by resetting buffers of veth names
in every iteration of creating veth.
* src/lxc/lxc_driver.c: prevent re-using auto-assigned veth name
Reported by Kumar L Srikanth-B22348.
Without this patch and with a clean environment, ./autobuild.sh
tried to use ./configure --prefix=/, and fails.
* autobuild.sh (AUTOBUILD_INSTALL_ROOT): Provide sensible
default. Suggested by Daniel P. Berrange.
<hostdev> address parsing previously attempted to detect the number
base: currently it is hardcoded to base 16, which can break PCI
assignment via virt-manager. Revert to the previous behavior.

virStrToLong_ui(bus, NULL, 0, ...) to autodetect base
This introduces a new event type
VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON
This event is the same as the previous VIR_DOMAIN_ID_IO_ERROR
event, but also includes a string describing the cause of
the event.
Thus there is a new callback definition for this event type
typedef void (*virConnectDomainEventIOErrorReasonCallback)(virConnectPtr conn,
virDomainPtr dom,
const char *srcPath,
const char *devAlias,
int action,
const char *reason,
void *opaque);

Introduce a function to notify the IP address learning
thread to terminate and thus release the lock on the interface.
Notify the thread before grabbing the lock on the interface
and tearing down the rules. This prevents a 'virsh destroy' to
tear down the rules that the IP address learning thread has
applied.
The functions invoked by the IP address learning thread
that apply some basic filtering rules did not clean up
any previous filtering rules that may still be there
(due to a libvirt restart for example). With the
patch below all the rules are cleaned up first.
Also, I am introducing a function to drop all traffic
in case the IP address learning thread could not apply
the rules.
The local DHCP server on virtbr0 sends DHCP ACK messages when a VM is
started and requests an IP address while the initial DHCP lease on the
VM's MAC address hasn't expired. So, also pick the IP address of the VM
if that type of message is seen.
Thanks to Gerhard Stenzel for providing a test case for this.
Changes from V1 to V2:
- cleanup: replacing DHCP option numbers through constants
Ubuntu's gntls package generates an Issuer line that looks like this:
Issuer: C=US,ST=NY,L=Rochester,O=example.com,CN=example.com CA,EMAIL=hostmaster@example.com
While Red Hat's looks like this
Issuer: CN=Red Hat Emerging Technologies
Note the leading whitespace, and the additional fields in the former.
This patch updates the regular expression to:
* trim leading characters before "Issuer:"
* trim anything between Issuer: and CN=
* trim anything after the next ,
I've tested this against the certool output of both RH and Ubuntu
generated certs.

Some applications need to be able to query a guest's disk info,
even for paths not managed by the storage pool APIs. This adds
a very simple API to get this information, modelled on the
virStorageVolGetInfo API, but with an extra field 'physical'.
Normally 'physical' and 'allocation' will be identical, but
in the case of a qcow2-like file stored inside a block device
'physical' will give the block device size, while 'allocation'
will give the qcow2 image size
* include/libvirt/libvirt.h.in: Define virDomainGetBlockInfo
When running virsh edit, we are unlinking and setting
the tmp variable to NULL before going to the end of the
function, meaning that we never free tmp. Since the
exit to the function will always unlink and free tmp,
just remove this bit of code and let it get done at the
end.

qemuDomainPCIAddressSetFree was freeing up the hash
table for the pci addresses, but not freeing up the addr
structure. Looking over the callers of this function, it
seems like they expect it to also free up the structure,
so do that here.

When building on Ubuntu with make -j3 (or more), it would always
fail when trying to build virt-aa-helper. I'm not an expert in
automake by any means, but I think the entry for virt-aa-helper
is mis-using LDADD; it shouldn't be putting direct paths to
libvirt_conf.la and libvirt_util.la, but instead referencing those
names. With this patch in place, I'm able to successfully build
on Ubuntu 9.04 with make -j3.
