The netsniff-ng toolkit's primary usage goal is to facilitate a network developer's / hacker's daily Linux plumbing. It can be used for network development, debugging, analysis, auditing or network reconnaissance. It consists of the following fixed set of utilities: * netsniff-ng: a zero-copy packet analyzer, pcap capturing/replaying tool * trafgen: a multithreaded low-level zero-copy network packet generator * mausezahn: high-level packet generator for HW/SW appliances with Cisco-CLI * ifpps: a top-like kernel networking and system statistics tool * curvetun: a lightweight curve25519-based multiuser IP tunnel * astraceroute: an autonomous system trace route and DPI testing utility * flowtop: a top-like netfilter connection tracking tool * bpfc: a Berkeley Packet Filter compiler, Linux BPF JIT disassembler Each release can be verified with Git and GPG, here are the steps to do so: 1) Import the maintainers public keys: git show maint-tklauser-pgp-pub | gpg --import git show maint-dborkman-pgp-pub | gpg --import 2) Verify the Git tag: git tag -v Carefully read the INSTALL document for the next steps in building netsniff-ng. Note that the toolkit is still quite young and under heavy development, not yet feature complete and in a quality level where we're satisfied with (i.e. for mausezahn). However, we're on a good way towards tackling all these goals. The netsniff-ng toolkit is an open source project covered by the GNU General Public License, version 2.0. For any questions or feedback about netsniff-ng you are welcome to leave us a message at . netsniff-ng is non-profit and provided in the hope, that it is found useful. The current project status can be considered as "working". In general, all tools have been tested by us to a great extend including their command-line options. In fact, many of our tools are used in a lot of production systems. However, we give no guarantee that our tools are free of bugs! If you spot some issues, contact us as described in REPORTING-BUGS. Also, have a look at our online FAQ for answering your questions. This project has received support from companies and institutions listed in Sponsors. Thanks for contributing, we're thrilled to provide you with netsniff-ng! Happy packet hacking! ce3d5aeca52445d1f5627c4ba'>whci/hw.c

perf/core: Fix PERF_RECORD_MMAP2 prot/flags for anonymous memory
Andres reported that MMAP2 records for anonymous memory always have their protection field 0. Turns out, someone daft put the prot/flags generation code in the file branch, leaving them unset for anonymous memory.
