7 years agovfio: fix file descriptor leak in multi-process
Patrick MacArthur [Thu, 26 Jan 2017 23:05:21 +0000 (18:05 -0500)]
vfio: fix file descriptor leak in multi-process

When a secondary process wants access to the VFIO container file
descriptor, the primary process calls vfio_get_container_fd() which
always opens an entirely new file descriptor on /dev/vfio/vfio.
However, once the file descriptor has been passed to the subprocess, it
is effectively duplicated, meaning that the copy of the file descriptor
in the primary process is no longer needed.  However, the primary
process does not close the duplicate fd, which results in a resource
leak.

This can be reproduced by starting a primary process with a small
RLIMIT_NOFILE limit configured to use VFIO for at least one device, and
repeatedly launching secondary processes until the file descriptor limit
is exceeded.

Fix the resource leak by closing the local vfio container file
descriptor after passing it to the secondary process.

Such writes could be very costly; it introduces severe cache issues:
The above operations introduce cache write for each packet, which
stalls the read operation from the vhost backend.

The fact that virtio net header is initiated to zero in PMD driver
init stage means that these costly writes are unnecessary and could
be avoided:

    if (hdr->csum_start != 0)

And that's what the macro ASSIGN_UNLESS_EQUAL does. With this, the

app/crypto-perf: introduce performance test application

This patchset introduce new application which allows measuring
performance parameters of PMDs available in crypto tree. The goal of
this application is to replace existing performance tests in app/test.
Parameters available are: throughput (--ptest throughput) and latency
(--ptest latency). User can use multiply cores to run tests on but only
one type of crypto PMD can be measured during single application
execution. Cipher parameters, type of device, type of operation and
chain mode have to be specified in the command line as application
parameters. These parameters are checked using device capabilities
structure.
Couple of new library functions in librte_cryptodev are introduced for
application use.
To build the application a CONFIG_RTE_APP_CRYPTO_PERF flag has to be set
(it is set by default).
Example of usage: -c 0xc0 --vdev crypto_aesni_mb_pmd -w 0000:00:00.0 --
--ptest throughput --devtype crypto_aesni_mb --optype cipher-then-auth
