19685d5aa7 igb_uio: allow multi-process access
In some case, one device are accessed by different processes via
different BARs, so one uio device may be opened by more than one
process, for this case we just need to enable interrupt once, and
pci_clear_master only when the last process closed.

0d440d081c lib: fix missing includes in exported headers
Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:

 grep -L '^#include <rte_config.h>' -- \
  $(grep -Rl \
    $(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
      build/include/rte_config.h) \
    -- build/include/)

We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.

This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:

 [...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
     this scope
  #define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
                                            ^

It also results in less visible issues, for instance rte_hash_crc.h relying
on RTE_ARCH_X86_64's presence to provide dedicated inline functions.

This patch partially reverts the commit below and adds missing include
lines to the remaining files.

57b4eafa1d vhost: support Explicit Congestion Notification
In virtio, Explicit Congestion Notification (ECN) includes two parts:
guest ECN and host ECN. Guest ECN means the frontend can handle TSO
packets which have ECN set, and host ECN means the backend can handle
TSO packets which have ECN set.

The ECN features are rarely used. However, virtio-net enables them by
default, and vhost-net support both. To make live migration from
vhost-net to vhost-user possible, this patch announces to support
guest and host ECN in vhost-user.

e37ff95440 vhost: support virtqueue interrupt/notification suppression
The driver can suppress interrupt when VIRTIO_F_EVENT_IDX feature bit is
negotiated. The driver set vring flags to 0, and MAY use used_event in
available ring to advise device interrupt util reach an index specified
by used_event. The device ignore the lower bit of vring flags, and send
an interrupt when index reach used_event.

The device can suppress notification in a manner analogous to the ways
driver suppress interrupt. The device manipulates flags or avail_event in
the used ring in the same way the driver manipulates flags or used_event in
available ring.

cebe3d7b3d ethdev: remove useless parameter in callback process
The pointer to the user parameter of the callback registration is
automatically pass to the callback function.
There is no point to allow changing this user parameter by a caller.
That's why this parameter is always set to NULL by PMDs and set only
in ethdev layer before calling the callback function.

The history is that the user parameter was initially used
by the callback implementation to pass some information
between the application and the driver:
	c1ceaf3ad0 ("ethdev: add an argument to internal callback function")
Then a new parameter has been added to leave the user parameter
to its standard usage of context given at registration:
	d6af1a13d7 ("ethdev: add return values to callback process API")

The NULL parameter in the internal callback processing function
is now removed. It makes clear that the callback parameter is user
managed and opaque from a DPDK point of view.

Bits are defined in ETH_LINK_SPEED_*.

Some numerical (ETH_SPEED_NUM_*) and boolean (ETH_LINK_*) values
are used for the link status (rte_eth_link.*).

There was a mistake in the comment of rte_eth_link.link_autoneg,

instead of ETH_LINK_[AUTONEG/FIXED] which are 1/0.

e291093235 vhost: destroy unused virtqueues when multiqueue not negotiated
QEMU sends VHOST_USER_SET_VRING_CALL requests for all queues
declared in QEMU command line before the guest is started.
It has the effect in DPDK vhost-user backend to allocate vrings
for all queues declared by QEMU.

If the first driver being used does not support multiqueue,
the device never changes to VIRTIO_DEV_RUNNING state as only
the first queue pair is initialized. One driver impacted by
this bug is virtio-net's iPXE driver which does not support
VIRTIO_NET_F_MQ feature.

It is safe to destroy unused virtqueues in SET_FEATURES request
handler, as it is ensured the device is not in running state
at this stage, so virtqueues aren't being processed.

07f8db29b8 vhost: prevent features to be changed while device is running
As section 2.2 of the Virtio spec states about features
negotiation:
"During device initialization, the driver reads this and tells
the device the subset that it accepts. The only way to
renegotiate is to reset the device."

This patch implements a check to prevent illegal features change
while the device is running.

One exception is the VHOST_F_LOG_ALL feature bit, which is enabled
when live-migration is initiated. But this feature is not negotiated
with the Virtio driver, but directly with the Vhost master.

cab278dee9 vhost: fix crash
In a running VM, operations (like device attach/detach) will
trigger the QEMU to resend set_mem_table to vhost-user backend.

DPDK vhost-user handles this message rudely by unmap all existing
regions and map new ones. This might lead to segfault if there
is pmd thread just trying to touch those unmapped memory regions.

But for most cases, except VM memory hotplug, QEMU still sends the
set_mem_table message even the memory regions are not changed as
QEMU vhost-user filters out those not backed by file (fd > 0).

To fix this case, we add a check in the handler to see if the
memory regions are really changed; if not, we just keep old memory
regions.

20d2159d46 malloc: fix end for bounded elements
In cases when alignment is bigger than boundary, we may incorrectly
calculate end of a bounded malloc element.

Consider this: suppose we are allocating a bounded malloc element
that should be of 128 bytes in size, bounded to 128 bytes and
aligned on a 256-byte boundary. Suppose our malloc element ends
at 0x140 - that is, 256 plus one cacheline.

So, right at the start, we are aligning our new_data_start to
include the required element size, and to be aligned on a specified
boundary - so new_data_start becomes 0. This fails the following
bounds check, because our element cannot go above 128 bytes from
the start, and we are at 320. So, we enter the bounds handling
branch.

While we're in there, we are aligning end_pt to our boundedness
requirement of 128 byte, and end up with 0x100 (since 256 is
128-byte aligned). We recalculate new_data_size and it stays at
0, however our end is at 0x100, which is beyond the 128 byte
boundary, and we report inability to reserve a bounded element
when we could have.

This patch adds an end_pt recalculation after new_data_start
adjustment - we already know that size <= bound, so we can do it
safely - and we then correctly report that we can, in fact, try
using this element for bounded malloc allocation.

f13d705a61 malloc: protect stats with lock
When we're gathering statistics, we are traversing the freelist,
which may change under our feet in multithreaded scenario. This
is verified by occasional segfaults when running malloc autotest
on a machine with big amount of cores.

This patch protects malloc heap stats call with a lock. It changes
its definition in the process due to locking invalidating the
const-ness, but this isn't a public API, so that's OK.

db22d31a79 memzone: fix leak on allocation error
We check if there's space in config after we allocated the memzone,
but if there isn't, we never free it back. This patch adds memzone
free if there's no room in memzone config.

1fa2c9e108 service: add reset all attributes for service
This commit introduces a new API, allowing the application to
reset attributes of a service like the cycle count. Given this
functionality is now exposed to the user, remove the resetting
of stats during a dump() call.
