Patches 1-3 are minor cleanups: replace the runtime speed capability function with a compile-time constant (TAP is always 10G), clarify TUN/TAP flag operator precedence with parentheses, and extend the fixed MAC index to 16 bits to avoid duplicates after 256 hot-plug cycles.
Patches 4-9 fix bugs tagged for stable: a bounds check to prevent an out-of-bounds read on truncated L4 headers; resource leaks in the primary and secondary process probe error paths; a missing free of the IPC reply buffer on queue count mismatch; a use-after-free with an orphaned kernel TC rule when remote flow creation fails; and a leaked remote_flow allocation on EEXIST from an implicit rule. Patch 10 adds a unit test suite for the TAP PMD modeled on the ring PMD tests, covering configuration, link, stats, MTU, MAC, promisc, allmulti, queue start/stop, link up/down, stop/start, and multi-queue. v4 - fix build on clang Stephen Hemminger (10): net/tap: replace runtime speed capability with constant net/tap: clarify TUN/TAP flag assignment net/tap: extend fixed MAC range to 16 bits net/tap: skip checksum on truncated L4 headers net/tap: fix resource leaks in tap create error path net/tap: fix resource leaks in secondary process probe net/tap: free IPC reply buffer on queue count mismatch net/tap: fix use-after-free on remote flow creation failure net/tap: free remote flow when implicit rule already exists test: add unit tests for TAP PMD app/test/meson.build | 1 + app/test/test_pmd_tap.c | 907 ++++++++++++++++++++++++++++++++++ drivers/net/tap/rte_eth_tap.c | 97 ++-- drivers/net/tap/tap_flow.c | 23 +- 4 files changed, 967 insertions(+), 61 deletions(-) create mode 100644 app/test/test_pmd_tap.c -- 2.51.0
