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

Add -R to netstat to dump RSS/flow information. This is intended to help in diagnostics and debugging of NIC and stack flowid support. Eventually this will grow another column (RSS CPU ID) but that currently isn't cached in the inpcb. There's also no clean flowtype -> flowtype identifier string. This is the mbuf M_HASHTYPE_* values for RSS. Here's some example output: adrian@adrian-hackbox:~/work/freebsd/head/src % netstat -Rn | more Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address flowid ftype tcp4 0 0 10.11.1.65.22 10.11.1.64.12409 29041942 2 udp4 0 0 127.0.0.1.123 *.* 00000000 0 udp6 0 0 fe80::1%lo0.123 *.* 00000000 0 udp6 0 0 ::1.123 *.* 00000000 0 udp4 0 0 10.11.1.65.123 *.* 00000000 0 Tested: * amd64 system w/ igb NIC; local driver changes to expose RSS flowid in if_igb.

Restore netstat -M functionality for most statistics on core dumps. In 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.

Add support for printing IPSEC protocol stats if the kernel was compiled with FAST_IPSEC rather than the KAME IPSEC stack. Note that the output of "netstat -s -p ipsec" differs depending on which stack is compiled into the kernel since they each keep different stats. This delta also adds the "esp", "ah", and "ipcomp" protocol stats, which are also available when the kernel is compiled with the FAST_IPSEC stack (e.g. "netstat -s -p esp").

Restore netstat -M functionality for most statistics on core dumps. In 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.

Modify netstat -mb to use libmemstat when accessing a core dump or live kernel memory and not using sysctl. Previously, libmemstat was used only for the live kernel via sysctl paths. This results in netstat output becoming both more consistent between core dumps and the live kernel, and also more information in the core dump case than previously (i.e., mbuf cache information). Statistics relating to sfbufs still rely on a kvm descriptor as they are not currently exposed via libmemstat. netstat -m operating on a core is still unable to print certain sfbuf stats available on the live kernel.
