eal: check if primary process is alive
This patch adds a new function to the EAL API:
int rte_eal_primary_proc_alive(const char *path);
The function indicates if a primary process is alive right now.
This functionality is implemented by testing for a write-
lock on the config file, and the function tests for a lock.
The use case for this functionality is that a secondary
process can wait until a primary process starts by polling
the function and waiting. When the primary is running, the
secondary continues to poll to detect if the primary process
has quit unexpectedly, the secondary process can detect this.

eal: fix race condition in multi-process startup
This patch fixes a race-condition when a primary and
secondary process simultaneously probe PCI devices.
This is implemented by moving the rte_eal_mcfg_complete()
function call in rte_eal_init() until after rte_eal_pci_probe().
The memory mapping of PCI device in the secondary process *must*
happen after the primary has finished doing the mapping as it
relies on information written by the primary.
The end result is that the secondary process waits longer,
until the primary has completed its PCI probing, and then
notifies the secondary process.
This race-condition became visible during the development of
a function that allows a secondary process to be polling until
a primary process exists. The secondary would then probe PCI
devices at the same time, causing an error during rte_eal_init()

be extended to other checks.
Failing build on warnings is a useful developer tool but its bad
for release tarballs which can and do get built with newer
compilers than what was used/available during development. Compilers
routinely add new warnings so code which built silently with cc X
might no longer do so with X+1. This doesn't make the existing code
any more buggier and failing the build in this case does not help
to improve the quality of an already released version either.

vhost: broadcast RARP by injecting in receiving mbuf array
Broadcast RARP packet by injecting it to receiving mbuf array at
rte_vhost_dequeue_burst().
Commit
33226236a35e ("vhost: handle request to send RARP") iterates
all host interfaces and then broadcast it by all of them. It did
notify the switches about the new location of the migrated VM, however,
the mac learning table in the target host is wrong (at least in my
test with OVS):
$ ovs-appctl fdb/show ovsbr0
port VLAN MAC Age
1 0 b6:3c:72:71:cd:4d 10
LOCAL 0 b6:3c:72:71:cd:4e 10
LOCAL 0 52:54:00:12:34:68 9
1 0 56:f6:64:2c:bc:c0 1
Where 52:54:00:12:34:68 is the mac of the VM. As you can see from the
above, the port learned is "LOCAL", which is the "ovsbr0" port. That
is reasonable, since we indeed send the pkt by the "ovsbr0" interface.
The wrong mac table lead all the packets to the VM go to the "ovsbr0"
in the end, which ends up with all packets being lost, until the guest
send a ARP quest (or reply) to refresh the mac learning table.
Jianfeng then came up with a solution I have thought of firstly but NAKed
by myself, concerning it has potential issues [0]. The solution is as title
stated: broadcast the RARP packet by injecting it to the receiving mbuf
arrays at rte_vhost_dequeue_burst(). The re-bring of that idea made me
think it twice; it looked like a false concern to me then. And I had done
a rough verification: it worked as expected.
[0]: http://dpdk.org/ml/archives/dev/2016-February/033527.html
Another note is that while preparing this version, I found that DPDK has
some ARP related structures and macros defined. So, use them instead of
the one from standard header files here.

Current implementation of Exact-Match uses different execution path than

Main changes:

* Packet classification stage is separated from the rest of path for both
LPM and EM.
* Packet processing, modifying and transmit part is the same for LPM and EM
and mostly based on the current LPM implementation.
* Shared code is moved to the common file "l3fwd_sse.h".
* While sequential packet classification in EM path, seems to be faster
than using multi hash lookup, used before, it is used by default. Old

4. Use ixia to inject packets in a small data bit rate.
Error:
vhost-switch keeps printing error message:
failed to allocate memory for mbuf.
Root cause:
How many mbufs allocated for a port is calculated by below formula.
NUM_MBUFS_PER_PORT = ((MAX_QUEUES*RTE_TEST_RX_DESC_DEFAULT) + \
(num_switching_cores*MAX_PKT_BURST) + \
(num_switching_cores*RTE_TEST_TX_DESC_DEFAULT) +\
(num_switching_cores*MBUF_CACHE_SIZE))
We suppose num_switching_cores is 1 and MBUF_CACHE_SIZE is 128.
And when initializing port, master core fills mbuf mempool cache,
so there would be some left in that cache, for example 121.
So total mbufs which can be used is:
(MAX_PKT_BURST + MBUF_CACHE_SIZE - 121) = (32 + 128 - 121) = 39.
What makes it worse is that there is a buffer to store mbufs
(which will be tx_burst to physical port), if it occupies some mbufs,
there will be possible < 32 mbufs left, so vhost dequeue prints out
this msg.
In all, it fails to include master core's mbuf mempool cache.

examples/l3fwd: modularize
The main problem with l3fwd is that it is too monolithic with everything
being in one file, and the various options all controlled by compile time
flags. This means that it's hard to read and understand, and when making
any changes, you need to go to a lot of work to try and ensure you cover
all the code paths, since a compile of the app will not touch large parts
of the l3fwd codebase.
Following changes were done to fix the issues mentioned above
- Split out the various lpm and hash specific functionality into separate
files, so that l3fwd code has one file for common code e.g. args
processing, mempool creation, and then individual files for the various
forwarding approaches.
Following are new file lists
main.c (Common code for args processing, memppol creation, etc)
l3fwd_em.c (Hash/Exact match aka 'EM' functionality)
l3fwd_em_sse.h (SSE4_1 buffer optimizated 'EM' code)
l3fwd_lpm.c (Longest Prefix Match aka 'LPM' functionality)
l3fwd_lpm_sse.h (SSE4_1 buffer optimizated 'LPM' code)
l3fwd.h (Common include for 'EM' and 'LPM')
- The choosing of the lpm/hash path should be done at runtime, not
compile time, via a command-line argument. This will ensure that
both code paths get compiled in a single go
Following examples show runtime options provided
Select 'LPM' or 'EM' based on run time selection f.e.
> l3fwd -c 0x1 -n 1 -- -p 0x1 -E ... (EM)
> l3fwd -c 0x1 -n 1 -- -p 0x1 -L ... (LPM)

of the rte_virtio_memory struct. This only works if the vhost-user code frees
dev->mem, since the common code is unaware of the extra info. The
VHOST_USER_RESET_OWNER message is one situation where the common code frees
dev->mem and leaks the fds and mappings. This happens every time I shut down a
VM.
The new code calls back into the implementation (vhost-user or vhost-cuse) to
clean up these resources.
The vhost-cuse changes are only compile tested.

To claim that we support vhost-user live migration support:

Besides this flag, we actually need another feature flag set

Which, however, has been enabled long time ago.

vhost: handle request to send RARP
While in former patch we enabled GUEST_ANNOUNCE feature, so that the
guest OS will broadcast a GARP message after migration to notify the
switch about the new location of migrated VM, the thing is that
GUEST_ANNOUNCE is enabled since kernel v3.5 only. For older kernel,
VHOST_USER_SEND_RARP request comes to rescue.
The payload of this new request is the mac address of the migrated VM,
with that, we could construct a RARP message, and then broadcast it
to host interfaces.
That's how this patch works:
- list all interfaces, with the help of SIOCGIFCONF ioctl command
- construct an RARP message and broadcast it

It's actually a feature already enabled in Linux kernel (since v3.5).
What we need to do is simply to claim that we support such feature,

With that, the guest will send an ARP message after live migration
to notify the switches about the new location of migrated VM.

Introduce vhost_log_write() helper function to log the dirty pages we

Therefore, vhost_log_write() simply finds the right bit for related

start of the dirty page bitmap.
Every time we update virtio used ring, we need to log it. And it's

VHOST_USER_SET_LOG_BASE request is used to tell the backend (dpdk

buffer is.
This request introduces a new payload:
typedef struct VhostUserLog {
uint64_t mmap_size;

} VhostUserLog;
Also, a fd is delivered from QEMU by ancillary data.
With those info given, an area of memory is mmaped, assigned

Commit
d0cf91303d73 added dependency on librte_net headers to vhost
but did not add this to the Makefile, which makes builds
non-deterministic. Curiously it is non-parallel build that is
consistently broken by this missing dependency, usually it's the other

vhost: add guest offload setting
Add guest offload setting in vhost lib.
Virtio 1.0 spec (5.1.6.4 Processing of Incoming Packets) says:
1. If the VIRTIO_NET_F_GUEST_CSUM feature was negotiated, the
VIRTIO_NET_HDR_F_NEEDS_CSUM bit in flags can be set: if so,
the packet checksum at offset csum_offset from csum_start
and any preceding checksums have been validated. The checksum
on the packet is incomplete and csum_start and csum_offset
indicate how to calculate it (see Packet Transmission point 1).
2. If the VIRTIO_NET_F_GUEST_TSO4, TSO6 or UFO options were
negotiated, then gso_type MAY be something other than
VIRTIO_NET_HDR_GSO_NONE, and gso_size field indicates the
desired MSS (see Packet Transmission point 2).
In order to support these features, the following changes are added,
1. Extend 'VHOST_SUPPORTED_FEATURES' macro to add the offload features negotiation.
2. Enqueue these offloads: convert some fields in mbuf to the fields in virtio_net_hdr.
There are more explanations for the implementation.
For VM2VM case, there is no need to do checksum, for we think the
data should be reliable enough, and setting VIRTIO_NET_HDR_F_NEEDS_CSUM
at RX side will let the TCP layer to bypass the checksum validation,
so that the RX side could receive the packet in the end.
In terms of us-vhost, at vhost RX side, the offload information is
inherited from mbuf, which is in turn inherited from TX side. If we
can still get those info at RX side, it means the packet is from
another VM at same host. So, it's safe to set the
VIRTIO_NET_HDR_F_NEEDS_CSUM, to skip checksum validation.
