* Fix netstat -gs with ip_mroute module and/or vnetMike Karels2019-11-121-6/+4
| | | | | | | | | | | | | | | | | | | | 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.Pedro F. Giffuni2017-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=325966

* Fix "netstat -gW" behavior broken in r259638.Alexander V. Chernikov2014-04-291-11/+13
| | | | | | | | | | | | | | | | 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.

* Introduce a number of changes to the MROUTING code.Bruce M Simpson2009-03-191-117/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is purely a forwarding plane cleanup; no control plane code is involved. Summary: * Split IPv4 and IPv6 MROUTING support. The static compile-time kernel option remains the same, however, the modules may now be built for IPv4 and IPv6 separately as ip_mroute_mod and ip6_mroute_mod. * Clean up the IPv4 multicast forwarding code to use BSD queue and hash table constructs. Don't build our own timer abstractions when ratecheck() and timevalclear() etc will do. * Expose the multicast forwarding cache (MFC) and virtual interface table (VIF) as sysctls, to reduce netstat's dependence on libkvm for this information for running kernels. * bandwidth meters however still require libkvm. * Make the MFC hash table size a boot/load-time tunable ULONG, net.inet.ip.mfchashsize (defaults to 256). * Remove unused members from struct vif and struct mfc. * Kill RSVP support, as no current RSVP implementation uses it. These stubs could be moved to raw_ip.c. * Don't share locks or initialization between IPv4 and IPv6. * Don't use a static struct route_in6 in ip6_mroute.c. The v6 code is still using a cached struct route_in6, this is moved to mif6 for the time being. * More cleanup remains to be merged from ip_mroute.c to ip6_mroute.c. v4 path tested using ports/net/mcast-tools. v6 changes are mostly mechanical locking and *have not* been tested. As these changes partially break some kernel ABIs, they will not be MFCed. There is a lot more work to be done here. Reviewed by: Pavlin Radoslavov Notes: svn path=/head/; revision=190012

* Restore netstat -M functionality for most statistics on core dumps. InJohn Baldwin2007-07-161-27/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | general, when support was added to netstat for fetching data using sysctl, no provision was left for fetching equivalent data from a core dump, and in fact, netstat would _always_ fetch data from the live kernel using sysctl even when -M was specified resulting in the user believing they were getting data from coredumps when they actually weren't. Some specific changes: - Add a global 'live' variable that is true if netstat is running against the live kernel and false if -M has been specified. - Stop abusing the sysctl flag in the protocol tables to hold the protocol number. Instead, the protocol is now its own field in the tables, and it is passed as a separate parameter to the PCB and stat routines rather than overloading the KVM offset parameter. - Don't run PCB or stats functions who don't have a namelist offset if we are being run against a crash dump (!live). - For the inet and unix PCB routines, we generate the same buffer from KVM that the sysctl usually generates complete with the header and trailer. - Don't run bpf stats for !live (before it would just silently always run live). - kread() no longer trashes memory when opening the buffer if there is an error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX. - The multicast routing code doesn't fallback to kvm on live kernels if the sysctl fails. Keeping this made the code rather hairy, and netstat is already tied to the kernel ABI anyway (even when using sysctl's since things like xinpcb contain an inpcb) so any kernels this is run against that have the multicast routing stuff should have the sysctls. - Don't try to dig around in the kernel linker in the netgraph PCB routine for core dumps. Other notes: - sctp's PCB routine only works on live kernels, it looked rather complicated to generate all the same stuff via KVM. Someone can always add it later if desired though. - Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered. - Use sysctlbyname() everywhere rather than hardcoded mib values.
