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.

Use the name 'IPv6 Forwarding Table', not 'IPv6 Routing Table', to be consistent with what the code actually does and is. 2007-02-21T13:41:51Z Bruce M Simpson bms@FreeBSD.org 2007-02-21T13:41:51Z urn:sha1:ab8e5cbf16612c38235d4f32f0d72f5b11041d22 loaded into the system. Change wording of comments to reflect the fact we should unconditionally use KVM if the -M option is used to specify a core file. Add comments to document the fact that IPv6 multicast forwarding information display still relies on KVM for gathering information. 2006-09-29T16:16:41Z Bruce M Simpson bms@FreeBSD.org 2006-09-29T16:16:41Z urn:sha1:910e1364b670fb71f8041575002b51a41c1ae2e4 Submitted by: ru 2006-09-29T15:45:11Z Bruce M Simpson bms@FreeBSD.org 2006-09-29T15:45:11Z urn:sha1:2d20d32344196de0b5a2ed6f911d26ae99232e99 2006-07-28T16:09:19Z Yaroslav Tykhiy ytykhiy@gmail.com 2006-07-28T16:09:19Z urn:sha1:7b95a1ebbd9aafe9f196a75d95c7b06eaee999a1 including to printf(). Using uintmax_t is also robust to further extensions in both the C language and the bitwidth of kernel counters.
