The current virRandomBits() API is only usable if the caller wants a random number in the range [0, n-1) where n is a power of two. This adds a virRandom() API which generates a double in the range [0.0,1.0) with 48 bits of entropy. It then also adds a virRandomInt(uint32_t max) API which generates an unsigned in the range [0,@max) Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

libvirt creates invalid commands if wrong locale is selected. For example with locale that uses comma as a decimal point, JSON commands created with decimal numbers are invalid because comma separates the entries in JSON. Fortunately even when decimal point is affected, thousands grouping is not, because for grouping to be enabled with *printf, there has to be an apostrophe flag specified (and supported). This patch adds specific internal function for converting doubles to strings with C locale.

This patch introduces a new error code VIR_ERR_OPERATION_UNSUPPORTED to mark error messages regarding operations that failed due to lack of support on the hypervisor or other than libvirt issues. The code is first used in reporting error if qemu does not support block IO tuning variables yielding error message: error: Unable to get block I/O throttle parameters error: Operation not supported: block_io_throttle field 'total_bytes_sec' missing in qemu's output instead of: error: Unable to get block I/O throttle parameters error: internal error cannot read total_bytes_sec

From man poll(2), poll does not set errno=EAGAIN on interrupt, however it does set errno=EINTR. Have libvirt retry on the appropriate errno. Under heavy load, a program of mine kept getting libvirt errors 'poll on socket failed: Interrupted system call'. The signals were SIGCHLD from processes forked by threads unrelated to those using libvirt.

This patch is in response to: https://bugzilla.redhat.com/show_bug.cgi?id=818467 If a caller to virCommandRun doesn't ask for the exitstatus of the program it's running, the virCommand functions assume that they should log an error message and return failure if the exit code isn't 0. However, only the commandline and exit status are logged, while potentially useful information sent by the program to stderr is discarded. Fortunately, virCommandRun is already checking if the caller had asked for stderr to be saved and, if not, sets things up to save it in *cmd->errbuf. This makes it fairly simple for virCommandWait to include *cmd->errbuf in the error log (there are still other callers that don't setup errbuf, and even virCommandRun won't set it up if the command is being daemonized, so we have to check that it's non-zero).

This introduces a fairly basic reference counted virObject type and an associated virClass type, that use atomic operations for ref counting. In a global initializer (recommended to be invoked using the virOnceInit API), a virClass type must be allocated for each object type. This requires a class name, a "dispose" callback which will be invoked to free memory associated with the object's fields, and the size in bytes of the object struct. eg, virClassPtr connclass = virClassNew("virConnect", sizeof(virConnect), virConnectDispose); The struct for the object, must include 'virObject' as its first member eg struct _virConnect { virObject object; virURIPtr uri; }; The 'dispose' callback is only responsible for freeing fields in the object, not the object itself. eg a suitable impl for the above struct would be void virConnectDispose(void *obj) { virConnectPtr conn = obj; virURIFree(conn->uri); } There is no need to reset fields to 'NULL' or '0' in the dispose callback, since the entire object will be memset to 0, and the klass pointer & magic integer fields will be poisoned with 0xDEADBEEF before being free()d When creating an instance of an object, one needs simply pass the virClassPtr eg virConnectPtr conn = virObjectNew(connclass); if (!conn) return NULL; conn->uri = virURIParse("foo:///bar") Object references can be manipulated with virObjectRef(conn) virObjectUnref(conn) The latter returns a true value, if the object has been freed (ie its ref count hit zero) Signed-off-by: NDaniel P.

All callers used the same initialization seed (well, the new viratomictest forgot to look at getpid()); so we might as well make this value automatic. And while it may feel like we are giving up functionality, I documented how to get it back in the unlikely case that you actually need to debug with a fixed pseudo-random sequence. I left that crippled by default, so that a stray environment variable doesn't cause a lack of randomness to become a security issue. * src/util/virrandom.c (virRandomInitialize): Rename...

There are a few issues with the current virAtomic APIs - They require use of a virAtomicInt struct instead of a plain int type - Several of the methods do not implement memory barriers - The methods do not implement compiler re-ordering barriers - There is no Win32 native impl The GLib library has a nice LGPLv2+ licensed impl of atomic ops that works with GCC, Win32, or pthreads.h that addresses all these problems. The main downside to their code is that the pthreads impl uses a single global mutex, instead of a per-variable mutex. Given that it does have a Win32 impl though, we don't expect anyone to seriously use the pthread.h impl, so this downside is not significant. * .gitignore: Ignore test case * configure.ac: Check for which atomic ops impl to use * src/Makefile.am: Add viratomic.c * src/nwfilter/nwfilter_dhcpsnoop.c: Switch to new atomic ops APIs and plain int datatype * src/util/viratomic.h: inline impls of all atomic ops for GCC, Win32 and pthreads * src/util/viratomic.c: Global pthreads mutex for atomic ops * tests/viratomictest.c: Test validate to validate safety of atomic ops.

No check for conn->uri being NULL in virAuthGetConfigFilePath (valid state) made the client segfault. This happens for example with these settings: - no virtualbox driver installed (modifies conn->uri) - no default URI set (VIRSH_DEFAULT_CONNECT_URI="", LIBVIRT_DEFAULT_URI="", uri_default="") - auth_sock_rw="sasl" - virsh run as root That are unfortunately the settings with fresh Fedora 17 installation with VDSM. The check ought to be enough as conn->uri being NULL is valid in later code and is handled properly.

Hello, This is a patch to fix vm's outbound traffic control problem. Currently, vm's outbound traffic control by libvirt doesn't go well. This problem was previously discussed at libvir-list ML, however it seems that there isn't still any answer to the problem. http://www.redhat.com/archives/libvir-list/2011-August/msg00333.html I measured Guest(with virtio-net) to Host TCP throughput with the command "netperf -H". Here are the outbound QoS parameters and the results. outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s] ====================================================================== 1024 (8Mbit/s) : 4.56 2048 (16Mbit/s) : 3.29 4096 (32Mbit/s) : 3.35 8192 (64Mbit/s) : 3.95 16384 (128Mbit/s) : 4.08 32768 (256Mbit/s) : 3.94 65536 (512Mbit/s) : 3.23 The outbound traffic goes down unreasonably and is even not controled. The cause of this problem is too large mtu value in "tc filter" command run by libvirt. The command uses burst value to set mtu and the burst is equal to average rate value if it's not set. This value is too large. For example if the average rate is set to 1024 kilobytes/s, the mtu value is set to 1024 kilobytes. That's too large compared to the size of network packets. Here libvirt applies tc ingress filter to Host's vnet(tun) device. Tc ingress filter is implemented with TBF(Token Buckets Filter) algorithm. TBF uses mtu value to calculate the amount of token consumed by each packet. With too large mtu value, the token consumption rate is set too large. This leads to token starvation and deterioration of TCP throughput. Then, should we use the default mtu value 2 kilobytes? The anser is No, because Guest with virtio-net device uses 65536 bytes as mtu to transmit packets to Host, and the tc filter with the default mtu value 2k drops packets whose size is larger than 2k. So, the most packets is droped and again leads to deterioration of TCP throughput. The appropriate mtu value is 65536 bytes which is equal to the maximum value of network interface device defined in <linux/netdevice.h>. The value is not so large that it causes token starvation and not so small that it drops most packets. Therefore this patch set the mtu value to 64kb(== 65535 bytes). Again, here are the outbound QoS parameters and the TCP throughput with the libvirt patched. outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s] ====================================================================== 1024 (8Mbit/s) : 8.22 2048 (16Mbit/s) : 16.42 4096 (32Mbit/s) : 32.93 8192 (64Mbit/s) : 66.85 16384 (128Mbit/s) : 133.88 32768 (256Mbit/s) : 271.01 65536 (512Mbit/s) : 547.32 The outbound traffic conforms to the given limit.
