3c79609fda vhost/crypto: handle virtually non-contiguous buffers
This patch enables the handling of buffers non-contiguous in
virtual address space in the vhost_crypto. Instead of using
rte_vhost_va_from_guest_pa(), the host virtual address is
converted by vhost_iova_to_vva() for wider use cases.

For copy mode, the copy length is limited to the chunk size,
next chunks VAs being fetched afterward.

460354cd4e mempool: fix virtual address population
Currently, populate_virt will check if mempool is already populated.
This will cause inability to reserve multi-chunk mempools if
contiguous memory is not a hard requirement, because if allocating
all-contiguous memory fails, mempool will retry with virtual addresses
and will call populate_virt. It seems that the original code never
anticipated more than one non-physically contiguous area.

Fix it by removing the check in populate virt. populate_anon() function
calls populate_virt() also, and it can be reasonably inferred that it is
expecting that virtual area is not already populated. Even though a
similar check is already in place there, also add the check that was
part of populate_virt() just in case.

3f697d2ee5 eal: move runtime directory creation after args parsing
The intention of the original code was to create runtime data
directory as early as possible, however it was moved too early,
before the arguments were parsed, resulting in --file-prefix

Fix this by moving eal_create_runtime_dir() to after command

56236363b4 eal: add directory for runtime data
Currently, during runtime, DPDK will store a bunch of files here
and there (in /var/run, /tmp or in $HOME). Fix it by creating a
DPDK-specific runtime directory, under which all runtime data
will be placed. The template for creating this runtime directory
is the following:

  <base path>/dpdk/<DPDK prefix>/

Where <base path> is set to either "/var/run" if run as root, or
$XDG_RUNTIME_DIR if run as non-root, with a fallback to /tmp if
$XDG_RUNTIME_DIR is not defined. So, for example, if run as root,
by default all runtime data will be stored at /var/run/dpdk/rte/.

There is no equivalent of "mkdir -p", so we will be creating the
path step by step.

Nothing uses this new path yet, changes for that will come in
next commit.

bafa9aa0d7 ethdev: fix port removal notification timing
When an ethdev port is released, a destroy event is triggered to notify
the users about the released port.

A bit before the destroy event is triggered, the port becomes invalid
by changing its state to UNUSED and cleaning its data. Therefore, the
port is invalid for the destroy event callback process and the users
may get a wrong information of the port.

Move the destroy event emitting to be called before the port
invalidation.

e06227e2fa ethdev: fix port visibility before initialization
The port was set to the state ATTACHED during allocation.
The consequence was to iterate over ports which are not initialized.

The state ATTACHED is now set as the last step of probing.

The uniqueness of port name is now checked before the availability
of a port id for allocation (order reversed).

As the state is not set on allocation anymore, it is also not checked
in the function telling whether a port is allocated or not.
The name of the port is set on allocation, so it is enough as a check.

fbe90cdd77 ethdev: add probing finish function
A new hook function is added and called inside the PMDs at the end
of the device probing:
	- in primary process, after allocating, init and config
	- in secondary process, after attaching and local init

This new function is almost empty for now.
It will be used later to add some post-initialization processing.

For the PMDs calling the helpers rte_eth_dev_create() or
rte_eth_dev_pci_generic_probe(), the hook rte_eth_dev_probing_finish()
is called from here, and not in the PMD itself.

Note that the helper rte_eth_dev_create() could be used more,
especially for vdevs, avoiding some code duplication in PMDs.

a4996bd89c ethdev: new Rx/Tx offloads API
This patch check if a input requested offloading is valid or not.
Any reuqested offloading must be supported in the device capabilities.
Any offloading is disabled by default if it is not set in the parameter
dev_conf->[rt]xmode.offloads to rte_eth_dev_configure() and
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If any offloading is enabled in rte_eth_dev_configure() by application,
it is enabled on all queues no matter whether it is per-queue or
per-port type and no matter whether it is set or cleared in
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If a per-queue offloading hasn't be enabled in rte_eth_dev_configure(),
it can be enabled or disabled for individual queue in
ret_eth_[rt]x_queue_setup().
A new added offloading is the one which hasn't been enabled in
rte_eth_dev_configure() and is reuqested to be enabled in
rte_eth_[rt]x_queue_setup(), it must be per-queue type,
otherwise trigger an error log.
The underlying PMD must be aware that the requested offloadings
to PMD specific queue_setup() function only carries those
new added offloadings of per-queue type.

This patch can make above such checking in a common way in rte_ethdev
layer to avoid same checking in underlying PMD.

This patch assumes that all PMDs in 18.05-rc2 have already
converted to offload API defined in 17.11 . It also assumes
that all PMDs can return correct offloading capabilities
in rte_eth_dev_infos_get().

In the beginning of [rt]x_queue_setup() of underlying PMD,
add offloads = [rt]xconf->offloads |
dev->data->dev_conf.[rt]xmode.offloads; to keep same as offload API
defined in 17.11 to avoid upper application broken due to offload
API change.
PMD can use the info that input [rt]xconf->offloads only carry
the new added per-queue offloads to do some optimization or some
code change on base of this patch.

3ff39e25e6 memzone: fix race condition on alloc failure
Deallocation used the wrong function, which could have resulted in
race conditions because the function does not use locks internally.

68c3603867 mem: unmap unneeded space
When we ask to reserve virtual areas, we usually include
alignment in the mapping size, and that memory ends up
being wasted. Wasting a gigabyte of VA space while trying to
reserve one gigabyte is pretty expensive on 32-bit, so after
we're done mapping, unmap unneeded space.

91fe57ac00 mem: check if allocation size is too big
Mapping size is a 64-bit integer, but mmap() will accept size_t for
size mappings. A user could request a mapping with an alignment, which
would have overflown size_t, so check if (size + alignment) will
overflow size_t.

33b3181791 eal: fix mempool ops name parsing
The code aimed to pick and remember the value of
mempool ops name from EAL command line arguments does not
copy the string and remembers the pointer provided
by getopt_long() directly. The latter could be clobbered
later and result in reading wrong mbuf pool ops name
by rte_mempool library.

Typically, this flaw could be avoided by using strdup()
to remember the string value of the option.
