It also removes problems of one process removing the\nsocket of another - which was the original issue reported. The main changes\nin this set are to:\n\n* disable telemetry for secondary processes, which prevents any socket\n conflicts in multi-process cases.\n* add a suffix to the telemetry sockets of any process run using\n \"in-memory\" mode. This suffix is the PID and ensures we don't get path\n conflicts on the sockets\n* inform the user of any path conflicts we do encounter for some reason,\n and present them with the options to solve it, instead of just removing\n the conflicting socket and continuing.\n [This was the original patch in V1-V3]\n* update the telemetry script and documentation to allow it to connect to\n in-memory DPDK processes.\n\n---\nV6: fixed issue whereby the failing of the legacy telemetry init would roll-back\ninit of the v2 telemetry, causing the socket to be deleted, even though it was\nstill necessary.\n\nV5: Rebase on latest main after other script cleanups were merged\n\nV4: Move from simple-fix patch to proper fix patchset\n\nV3: Drop CC stable, as will have separate backport patch which does not\nerror out, so avoiding causing problems with currently running application\n\nV2: fix build error on FreeBSD\n\nBruce Richardson (5):\n eal: limit telemetry to primary processes\n telemetry: fix deletion of active sockets\n telemetry: use unique socket paths for in-memory mode\n usertools/dpdk-telemetry: connect to in-memory processes\n usertools/dpdk-telemetry: provide info on available sockets\n\n doc/guides/howto/telemetry.rst | 26 +++++++++++++++++-\n lib/eal/freebsd/eal.c | 3 +-\n lib/eal/linux/eal.c | 3 +-\n lib/telemetry/telemetry.c | 43 +++++++++++++++++++++++------\n lib/telemetry/telemetry_internal.h | 3 +-\n usertools/dpdk-telemetry.py | 44 ++++++++++++++++++++++++++++--\n 6 files changed, 106 insertions(+), 16 deletions(-)\n\n--\n2.30.2" }
