This series fixes minor issues found by static analysis tools in the main passt code and in documentation examples. The core code changes add missing fd initialisations and guard unsigned arithmetic against potential underflow. We also fix buffer handling, type mismatches, and resource leaks in the documentation example code. v2: - udp_vu, tap: Use if-guards instead of assert(), to handle the error paths properly and let the static checker follow the logic - doc/migration: Use snprintf() instead of strncpy() for clarity and guaranteed null-termination (David Gibson) - Drop va_list initialisation patch (Stefano Brivio, David Gibson) Jon Maloy (6): passt: Initialise listening socket fds to -1 udp_vu: Check iov_tail_clone() return before assigning to msg_iovlen tap: Guard IPv6 tail size subtraction against underflow doc/migration: Use snprintf() for socket path and fix argv access doc/migration: Fix buffer type mismatch in recv() call doc/platform-requirements: Close leaked sockets in test_close_dup() doc/migration/source.c | 2 +- doc/migration/target.c | 10 ++++------ doc/platform-requirements/udp-close-dup.c | 3 +++ passt.c | 3 +++ tap.c | 5 ++++- udp_vu.c | 8 ++++++-- 6 files changed, 21 insertions(+), 10 deletions(-) -- 2.52.0
