the alarm would still trigger. The comment noted that cleanup
would happen in the alarm handler, but that's not what actually
happened - instead, in the event of failed send we freed the
memory in-place, before putting the request on the queue.

This works OK when the message is sent, but when sending the
message fails, the alarm would still trigger with a pointer
argument that points to non-existent memory, and cause
memory corruption.

There probably is a "proper" fix for this issue, with correct

test: fix hugepage file handling in EAL flags autotest

Before 18.05, DPDK could not release memory back to the system
neither at runtime nor before shutting down. Over the course of
18.05 up to 18.11, code was introduced to release memory at
runtime, as well as an rte_eal_cleanup() function that is supposed
to release all EAL-allocated memory before shutting down DPDK.

When 3f9e31d71d63 ("test: clean up on exit") was introduced, the
test application started to use rte_eal_cleanup() to release all
used memory after execution. However, the EAL flags autotest
still relies on the old behavior of leaving stuff behind in the
hugetlbfs.

The fix is twofold. First, the test to check for leftover files
in hugetlbfs is no longer valid as it is, because test application
now removes all files from hugetlbfs after exit. However, if we
use the --legacy-mem option, then old behavior of leaving files
in hugetlbfs after execution is restored. So the first fix is to
add --legacy-mem to all the tests that expect files in hugetlbfs
to be leftover.

However, we also need to test if default memory mode *doesn't*
leave any files behind, so we also extend the test to check for
these scenarios as well. So, both memtest1 and memtest2 are run
in legacy and default mem modes, and are checked for any leftover
files that are or are not supposed to be there.

net/mlx5: add MPLS to Direct Verbs flow engine

The support in MPLS on this flow engine was overlooked. It's absence is
critical because there are required actions for MPLS which can be done
only with the DV engine.

To set correctly the MPLS filter, we need to reason about the flow item
before the MPLS (UDP, GRE or other).
To do that, a new variable last_item was added and updated after each
translation. the full item flags are updated after each item iteration.

offload the skip_sw flag should be specified while applying the

perform hardware offload. If kernel succeeded the in_hw flag
is set in rule properties and application should check this
flag to get know whether the applied rule is actually hardware

to flags field into translated rule is introduced and flags are
tested directly in the rule body. It is more reliable than save and
check flags copy.

malloc: fix adjacency check to also include segment list

It may so happen that two memory locations may be adjacent in
virtual memory, but belong to different segment lists. With
current code, such segments will be concatenated. Fix the
adjacency checking code to also check if the adjacent malloc
elements belong to the same memseg list.

mem: check for contiguousness in external segments

For IOVA as VA mode, we assume that memory is contiguous. However,
for external segments that assumption may not necessarily hold.
Fix the code to not assume that external memory segments are
contiguous even in IOVA as VA mode.

5 years agoeal: fix duplicate function declaration

eal: fix duplicate function declaration

The rte_eal_get_runtime_dir() function is currently being declared in two
header files.

This API was made public in commit 6911c9fd8fbe ("eal: export function to
get runtime directory"), adding it to rte_eal.h. To make it public, the
'rte' prefix was added to the function so it needed to be modified in the
original location of the declaration, eal_filesystem.h.  By only modifying,
and not removing the decalration, it is now a duplicate.

This patch removes the declaration from eal_filesystem.h.
