IPSec Multi buffer library supports encryption on multiple segments.
When dealing with chained buffers (multiple segments), as long as
the operation is in-place, the destination buffer does not have to

examples/ipsec-secgw: fix GCM IV length

The example IPsec application does not work properly when using
AES-GCM with crypto_openssl.

ESP with AES-GCM uses standard 96bit long algorithm IV ([1]) which
later concatenated with be32(1) forms a J0 block. GCM specification
([2], chapter 7.1) states that when length of IV is different than
96b, in order to format a J0 block, GHASH function must be used.

According to specification ([2], chapter 5.1.1) GCM implementations
should support standard 96bit IVs, other lengths are optional. Every
DPDK cryptodev supports 96bit IV and few of them supports 128bit
IV as well (openssl, mrvl, ccp). When passing iv::length=16 to a
cryptodev which does support standard IVs only (e.g. qat) it
implicitly uses starting 96 bits. On the other hand, openssl follows
specification and uses GHASH to compute J0 for that case which results
in different than expected J0 values used for encryption/decryption.

Fix an inability to use AES-GCM with crypto_openssl by changing IV
length to the standard value of 12.

"""

If someone still needs to generate the graphs, the following can

Previously rx/tx_queues were passed into eth_from_pcaps_common()
as ptrs and were checked for being NULL.

In commit da6ba28f0540 ("net/pcap: use a struct to pass user options")
that changed to pass in a ptr to a pmd_devargs_all which contains
the rx/tx_queues.

The parameter checking was not updated as part of that commit and
coverity caught that there was still a check if rx/tx_queues were
NULL, apparently after they had been dereferenced.

In fact as they are a members of the devargs_all struct, they will
not be NULL so remove those checks.

5 years agovfio: fix DMA mapping of external heaps
Anatoly Burakov [Tue, 5 Nov 2019 15:15:12 +0000 (15:15 +0000)]
vfio: fix DMA mapping of external heaps

Currently, externally created heaps are supposed to be automatically
mapped for VFIO DMA by EAL, however they only do so if, at the time of
heap creation, VFIO is initialized and has at least one device
available. If no devices are available at the time of heap creation (or
if devices were available, but were since hot-unplugged, thus dropping
all VFIO container mappings), then VFIO mapping code would have skipped
over externally allocated heaps.

The fix is two-fold. First, we allow externally allocated memory
segments to be marked as "heap" segments. This allows us to distinguish
between external memory segments that were created via heap API, from
those that were created via rte_extmem_register() API.

Then, we fix the VFIO code to only skip non-heap external segments.
Also, since external heaps are not guaranteed to have valid IOVA
addresses, we will skip those which have invalid IOVA addresses as well.

5 years agomempool: reduce wasted space on populate
Olivier Matz [Tue, 5 Nov 2019 15:37:01 +0000 (16:37 +0100)]
mempool: reduce wasted space on populate

The size returned by rte_mempool_op_calc_mem_size_default() is aligned
to the specified page size. Therefore, with big pages, the returned size
can be much more that what we really need to populate the mempool.

For instance, populating a mempool that requires 1.1GB of memory with
1GB hugepages can result in allocating 2GB of memory.

This problem is hidden most of the time due to the allocation method of
rte_mempool_populate_default(): when try_iova_contig_mempool=true, it
first tries to allocate an iova contiguous area, without the alignment
constraint. If it fails, it fallbacks to an aligned allocation that does
not require to be iova-contiguous. This can also fallback into several
smaller aligned allocations.

This commit changes rte_mempool_op_calc_mem_size_default() to relax the
alignment constraint to a cache line and to return a smaller size.

5 years agodoc: fix description of links to EAL options pages

doc: fix description of links to EAL options pages

Documentation includes separate pages of EAL command-line options for
Linux and for FreeBSD.
Links to these pages use the same text 'EAL parameters', so it is not
clear which link to use for which environment.

This patch adds the text '(Linux)' and '(FreeBSD)' where relevant, to
clearly identify the links.

5 years agousertools: fix pmdinfo with python 3 and pyelftools>=0.24
Robin Jarry [Tue, 15 Oct 2019 12:39:17 +0000 (14:39 +0200)]
usertools: fix pmdinfo with python 3 and pyelftools>=0.24

Running dpdk-pmdinfo.py on Ubuntu 18.04 (bionic) with python 3 and
pyelftools installed produces no output but no error is reported
neither:

  ~$ python3 usertools/dpdk-pmdinfo.py -r build/app/testpmd
  ~$ echo $?
  0

While with python 2, it works:

  ~# python2 usertools/dpdk-pmdinfo.py -r build/app/testpmd
  {"pci_ids": [], "name": "dpio"}
  {"pci_ids": [], "name": "dpbp"}
  {"pci_ids": [], "name": "dpaa2_qdma"}
  .....

On Ubuntu 18.04, pyelftools is version 0.24. The change log of
pyelftools v0.24 says:

 - Symbol/section names are strings internally now, not bytestrings
   (this may affect API usage in Python 3) (#76).

We cannot guess which version of pyelftools is actually being used. The
elftools.__version__ symbol is not consistent with each distro's package
version. For example, on Ubuntu 16.04 (xenial), the .deb package version
is '0.23-2' but elftools.__version__ contains '0.25'. This is certainly
due to partial backports.

To have a more consistent behaviour of this script across all versions
of python, add the unicode_literals future import so that literal
strings are now always "unicode".

Add 2 utility functions to force a string into bytes or bytes into an
unicode string.

Force pyelftools return values to unicode strings (will do nothing with
recent version of pyelftools).

If elffile.get_section_by_name returns None with a unicode section name,
try with the same one encoded as bytes.

Also, replace all open() calls by io.open() which behaves like the
builtin open in python 3. The only non-binary opened file is
/usr/share/hwdata/pci.ids which is UTF-8 encoded text. Explicitly
specify that encoding.
