Also with this one, it is a cast that always occurred
and is just being done explicitly, with no changes to
the generated code.

The warning stack is misleading, it points to the last
element in the macro that produced the lhs of the subtraction
above.  But the only "unsigned long int" in the expression is
the result of the sizeof() on the rhs, it promotes the
subtraction result to unsigned long.  So the error actually
relates to the result of the outer subtraction.

The actual error is "you are trying to put an unsigned long
into a uint32_t".  We always did so, the fix is just to inform
the compiler it is intentional with an explicit cast.

flow isolation) may result in a TAP error:

again when enabling flow isolation. As a result this rule is added
two times in a row which results in "File exists" error.
The fix is to identify the "File exists" error and silently ignore it.

row in which case the same tc rules are added consecutively and
rte_flow structs are added to a linked list before removing the

Anatoly Burakov [Mon, 14 May 2018 16:06:15 +0000 (17:06 +0100)]
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.

Anatoly Burakov [Mon, 14 May 2018 16:27:41 +0000 (17:27 +0100)]
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
