These sub devices are hidden in the\nnormal iteration over ports but some applications use a direct\nport mask. In these cases, user may still (incorrectly) try\nto directly use the sub devices.\n\nThis patch set introduces a helper function to check if\na port is under ownership. And the follow on patches use that.\n\nIMHO this should not be marked as experimental and done as\na bug fix back to DPDK 18.11 because then it will get picked\nup in LTS and users won't run into it on Azure.\n\nAn alternative proposed in earlier discussion is to have\neach application try and own the port. But this solution would\nbe more invasive, and does not handle the case if secondary process\nexits prematurely without releasing ownership. It makes more\nsense to keep the concept of ownership as strictly part of\nthe device model and not part of the application layer.\n\nStephen Hemminger (7):\n ethdev: add function to test port ownership\n examples/l2fwd-cat: block attempts to use owned ports\n examples/l3fwd: block attempts to use owned ports\n examples/l3fwd-acl: block attempts to use owned ports\n examples/l3fwd-power: block attempts to use owned ports\n examples/tep_termination: block attempts to use owned ports\n examples/vhost: block attempts to use owned ports\n\n examples/l2fwd-cat/Makefile | 2 ++\n examples/l2fwd-cat/l2fwd-cat.c | 3 +++\n examples/l2fwd-cat/meson.build | 1 +\n examples/l3fwd-acl/Makefile | 3 +++\n examples/l3fwd-acl/main.c | 4 ++++\n examples/l3fwd-acl/meson.build | 1 +\n examples/l3fwd-power/main.c | 4 ++++\n examples/l3fwd/Makefile | 3 +++\n examples/l3fwd/main.c | 4 ++++\n examples/l3fwd/meson.build | 1 +\n examples/tep_termination/Makefile | 2 ++\n examples/tep_termination/main.c | 2 +-\n examples/tep_termination/meson.build | 1 +\n examples/vhost/main.c | 2 +-\n lib/librte_ethdev/rte_ethdev.c | 9 +++++++++\n lib/librte_ethdev/rte_ethdev.h | 15 +++++++++++++++\n lib/librte_ethdev/rte_ethdev_version.map | 3 +++\n 17 files changed, 58 insertions(+), 2 deletions(-)" }
