Allow debugging of GNUTLS interactions by setting
LIBVIRT_GNUTLS_DEBUG=10 LIBVIRT_DEBUG=1 virsh
* src/remote/remote_driver.c: Use LIBVIRT_GNUTLS_DEBUG to
enable gnutls debugging
For example, virsh -c test:///default schedinfo 1 --set P=k would
mistakenly exit successfully, giving no indication that it had failed
to set the scheduling parameter "P".
* tools/virsh.c (cmdSchedinfo): Diagnose an invalid --set j=k option,
rather than silently ignoring it.
* tests/virsh-schedinfo: New test for the above.
* tests/Makefile.am (test_scripts): Add it.

Some shells warn about missing programs before redirection;
the idiomatic way to silence them is to run the program check
inside a subshell, with the redirections outside the subshell.
But a subshell is only needed in places where it is reasonable
to expect the use of such a noisy shell in the first place.
* src/Makefile.am (remote_protocol-structs): Use subshell, for
FreeBSD 8.0 /bin/sh.
* cfg.mk (sc_preprocessor_indentation): Avoid subshell, since the
only users running cfg.mk can be assumed to have decent tools.
For printf("%*s",foo,bar), clang complains if foo is not int:
warning: field width should have type 'int', but argument has
type 'unsigned int' [-Wformat]
* src/conf/storage_encryption_conf.c
(virStorageEncryptionSecretFormat, virStorageEncryptionFormat):
Use correct type.
* src/conf/storage_encryption_conf.h (virStorageEncryptionFormat):
Likewise.
Now, if you update remote_protocol.x without also updating
remote_protocol-structs to match, then "make check" will fail.
* src/Makefile.am (remote_protocol-structs): Extract list of
structs and member names from remote_protocol.o.
(check-local): Depend on it.
* src/remote_protocol-structs: New file.
Right now, mingw32-portablexdr is not available in Fedora, but is
present in fedora-mingw.git. With that package, plus
redhat-rpm-config and this patch, it is once again possible to build
mingw32-libvirt from a Fedora 12 host.
* mingw32-libvirt.spec.in (__debug_install_post): Override.
(%files): Mention recent additions.
This reverts commit b5b8a6db69.
That commit was not necessary. The problem is fixed by commit
0e9b3a269b, but I didn't rebuild
it properly after pulling in the commit and didn't notice it.
Per automake, LDFLAGS is used early in the line, and LIBADD
(libraries) or LDADD (programs) is used late. On platforms like
cygwin, without lazy linking, this order matters. Therefore, libtool
commands, -L, and similar should be in LDFLAGS, but -l should be in
L*ADD.
* src/Makefile.am (*_LDFLAGS): Move libraries...
(*_LIBADD): ...to their LIBADD counterpart.
Change 965466c1 added a new field to struct remote_error, which broke
the RPC protocol. Fortunately the new field is unused, so this change
simply removes it again.
* src/remote/remote_protocol.(c|h|x): Remove remote_nwfilter from struct
remote_error
With the introduction of the generic qemu device model, unplugging
SCSI disks works like a charm, so support it in libvirt.
* src/qemu/qemu_driver.c: Add qemudDomainDetachSCSIDiskDevice() to do the
unplugging, extend qemudDomainDetachDeviceAdd().

* 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.

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.
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
