Restore netstat -M functionality for most statistics on core dumps. In 2007-07-16T17:15:55Z John Baldwin jhb@FreeBSD.org 2007-07-16T17:15:55Z urn:sha1:feda1a4372d5e340da97042375dfb783dea52eda 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.

Using uintmax_t is also robust to further extensions in both the C language and the bitwidth of kernel counters. Tested on: i386 amd64 ia64 Add __FBSDID. Replace local variable sin by sockin to not conflict with sin(3). 2004-07-26T20:18:11Z Philippe Charnier charnier@FreeBSD.org 2004-07-26T20:18:11Z urn:sha1:6cc6f12231c7267d34a409cfbd960c7f3d69f8eb Use warnx() instead of warn() when error message is not of any interest.

Also, as long as I'm plowing up struct sockbuf ... Change certain members from u_long/long to u_int/int in order to reduce wasted space on 64-bit machines. This change was requested by Andrew Gallatin. Netstat and systat need to be rebuilt. I am incrementing __FreeBSD_version in case any ports need to change. Don't misuse the return from snprintf. 2001-08-20T11:58:05Z Brian Somers brian@FreeBSD.org 2001-08-20T11:58:05Z urn:sha1:2aad70eb9ecbd01c3137d1e7d2a879baa38889bb MFC after: 2 weeks remove warnings 2001-06-15T23:55:45Z Assar Westerlund assar@FreeBSD.org 2001-06-15T23:55:45Z urn:sha1:f964d60dd3287932055bfdaadf3cba4a7ff2d648 remove superfluous declarations make things more consistent remove K&R support 2001-06-15T23:35:13Z Assar Westerlund assar@FreeBSD.org 2001-06-15T23:35:13Z urn:sha1:5e0517186d418529323a5eb007287145e4fd3b50 revert removal of warning and K&R support 2001-06-15T23:07:59Z Assar Westerlund assar@FreeBSD.org 2001-06-15T23:07:59Z urn:sha1:e9370a2e59648a97d70bd008b7d8ad1124cc5f56 Requested by: bde
