This series fixes minor issues found by code coverage tools in the main passt code and in documentation examples. The core code changes addresses missing fd initialisations and explicit invariant checks for unsigned arithmetic. We also fix address buffer handling, type mismatches, uninitialised variables, and resource leaks in the documentation example code. Jon Maloy (7): passt: Initialise listening socket fds to -1 udp_vu: Assert iov_tail_clone() return before assigning to msg_iovlen tap: Assert IPv6 tail size before subtracting header length doc/migration: Use strncpy() for socket path and fix argv access doc/migration: Fix buffer type mismatch in recv() call doc/platform-requirements: Initialise va_list before va_start() doc/platform-requirements: Close leaked sockets in test_close_dup() doc/migration/source.c | 2 +- doc/migration/target.c | 10 ++++------ doc/platform-requirements/common.h | 2 +- doc/platform-requirements/udp-close-dup.c | 3 +++ passt.c | 3 +++ tap.c | 4 +++- udp_vu.c | 7 +++++-- 7 files changed, 20 insertions(+), 11 deletions(-) -- 2.52.0
