with only one hugepage or already sorted hugepage addresses, the sort
function called memcpy with same src and dst pointer. Debugging with

the sort method to qsort to avoid this behavior. The separate sort

b2bb3a5daa mk: stop on warning only in developer build
Add RTE_DEVEL_BUILD make-variable which can be used to do things
differently when doing development vs building a release,
autodetected from source root .git presence and overridable via
commandline. It is used it to enable -Werror compiler flag and may
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.

This change the default flags which can be tuned with EXTRA_CFLAGS.

948fd64bef mk: replace the combined library with a linker script
The physically linked-together combined library has been an increasing
source of problems, as was predicted when library and symbol versioning
was introduced. Replace the complex and fragile construction with a
simple linker script which achieves the same without all the problems,
remove the related kludges from eg mlx drivers.

Since creating the linker script is practically zero cost, remove the
config option and just create it always.

Based on a patch by Sergio Gonzales Monroy, linker script approach
initially suggested by Neil Horman.

Attached the wiki page about duff's device. It explains the performance
optimization through loop unwinding, and also the most dramatic use of
case label fall-through.

In this implementation, while() loop is used because we could not assume
count is strictly positive. Using while() loop saves one line of check.

bb66588304 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 33226236a3 ("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.

94c54b4158 examples/l3fwd: rework exact-match
Current implementation of Exact-Match uses different execution path than
for LPM. Unifying them allows to reuse big part of LPM code and sightly
increase performance of Exact-Match.

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
  implementation is moved to the file l3fwd_em_hlm_sse.h and can be enabled
  with HASH_LOOKUP_MULTI global define in compilation time.

5499c1fc9b examples/vhost: fix mbuf allocation
How to reproduce:

1. Start vhost-switch
./examples/vhost/build/vhost-switch -c 0x3 -n 4 -- -p 1 --stat 0
2. Start VM with a virtio port
$ $QEMU -smp cores=2,sockets=1 -m 4G -cpu host -enable-kvm \
  -chardev socket,id=char1,path=<path to vhost-user socket> \
  -device virtio-net-pci,netdev=vhostuser1 \
  -netdev vhost-user,id=vhostuser1,chardev=char1
  -object memory-backend-file,id=mem,size=4G,mem-path=<hugetlbfs path>,share=on \
  -numa node,memdev=mem -mem-prealloc \
  -hda <path to VM img>
3. Start l2fwd in VM
$ ./examples/l2fwd/build/l2fwd -c 0x1 -n 4 -m 1024 -- -p 0x1
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.

268888b5b0 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)
  Options "E" and "L" are mutualy-exclusive.
  If none selected, "L" is default.

C++ requires to use a scope operator to access an enum inside a struct.
There was also a namespace issue for the values (no RTE prefix).
The solution is to move the struct and related code out of the header file.

a90ca1a12e vhost: remove device operations pointers
The vhost_net_device_ops indirection is unnecessary because there is only
one implementation of the vhost common code.
Removing it makes the code more readable.

86f36ff957 mempool: fix leak when creation fails
Since commits ff909fe21f and 4e32101f9b, it is now possible to free
memzones and rings.

The rte_mempool_create() should be modified to take advantage of this
and not leak memory when an allocation fails.

ca67ed289a vhost: fix leak of fds and mmaps
The common vhost code only supported a single mmap per device. vhost-user
worked around this by saving the address/length/fd of each mmap after the end
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.

d639996a74 vhost: enable log_shmfd protocol feature
To claim that we support vhost-user live migration support:
SET_LOG_BASE request will be send only when this feature flag
is set.

Besides this flag, we actually need another feature flag set
to make vhost-user live migration work: VHOST_F_LOG_ALL.
Which, however, has been enabled long time ago.

33226236a3 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

d293dac8f3 vhost: claim support of guest announce
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,
and nothing else.

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