Fix netstat -gs with ip_mroute module and/or vnet

2019-11-12T01:03:08Z

The code for "netstat -gs -f inet" failed if the kernel namelist did not include the _mrtstat symbol. However, that symbol is not in a standard kernel even with the ip_mroute module loaded, where the functionality is available. It is also not in a kernel with MROUTING but also VIMAGE, as there can be multiple sets of stats. However, when running the command on a live system, the symbol is not used; a sysctl is used. Go ahead and try the sysctl in any case, and complain that IPv4 MROUTING is not present only if the sysctl fails with ENOENT. Also fail if _mrtstat is not defined when running on a core file; netstat doesn't know about vnets, so can only work if MROUTING was included, and VIMAGE was not.

spdx: initial adoption of licensing ID tags.

2017-11-18T14:26:50Z

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Initially, only tag files that use BSD 4-Clause "Original" license. RelNotes: yes Differential Revision: https://reviews.freebsd.org/D13133

Simplify kvm symbol resolution and error handling. The symbol table

nl_symbols will eventually be organized into several modules depending on MK_* variables.

- Add -W flag support for network column in intpr() (-i flag) and

2015-09-01T08:42:04Z

routepr() (-r flag). It is too narrow to show an IPv6 prefix in most cases. - Accept "local" as a synonym of "unix" in protocol family name. - Show a prefix length in CIDR notation when name resolution failed in netname(). - Make routename() and netname() AF-independent and remove unnecessary typecasting from struct sockaddr. - Use getnameinfo(3) to format L2 addr in intpr(). - Fix a bug which showed "Address" when -A flag is specfied in pr_rthdr(). - Replace cryptic GETSA() macro with SA_SIZE(). - Fix declarations shadowing local variables with the same names. - Add more static, remove unused header files and variables.

Fix "netstat -gW" behavior broken in r259638.

2014-04-29T16:51:28Z

netstat has two options for printing multicast tables: sysctl (the default one for live systems) and kvm-based one (for cores). It looks like kvm-based one hasn't been working since it's been introduced in r190012 due to absence of mfctablesize kernel symbol. Check for all ipv4-multicast symbols being correctly resolved was introduced in r259638 regardless of 'live' value leading to "No IPv4 MROUTING" error message.
