There is a race condition between the moment a netlink socket is created and the moment it is reported via SOCK_DIAG_BY_FAMILY interface. Add one more operation on the socket created by create_nl_socket to increase chances of winning the race. * tests/create_nl_socket.c (create_nl_socket_ext): Add a getsockopt call with the created socket.
strace - the linux syscall tracer
This is strace -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.
strace is released under a Berkeley-style license at the request of Paul Kranenburg; see the file COPYING for details.
See the file NEWS for information on what has changed in recent versions.
Please read the file INSTALL-git for installation instructions.
The user discussion and development of strace take place on the strace mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to strace-devel@lists.sourceforge.net. The mailing list archives are available at https://sourceforge.net/p/strace/mailman/strace-devel/ and other archival sites.
