rpaulo d65009381e Request process information using sysctl(3) and not kvm(3) since bpf(4) 
statistics and peers are only available using the former.
 2005-09-02 22:23:13 +00:00
rpaulo 66daeed445 Implemented the userland part of the BPF statistics and BPF peers, 
net.bpf.stats and net.bpf.peers sysctls respectively. netstat(1) now
has an additional syntax:
	netstat [-s] [-B] [-I Interface]

Only the super user can see a list of BPF peers with the following command:
# netstat -B
Active BPF peers
PID     Int     Recv     Drop     Capt     Flags  Bufsize  Comm
4941    lo0     0        0        0        I--S-  262144   tcpdump
252     ex0     19668    0        5        I-RS-  32768    dhclient

And every user can see the BPF statistics with:
$ netstat -s -B
bpf:
        19669 total packets received
        5 total packets captured
        0 total packets dropped

This idea came from FreeBSD (Christian S.J. Peron) but, currently, they
doen't have a userland utility in the base system to read the sysctls.

jonathan 85b3ba5bf1 Redo net.inet.* sysctl subtree for fast-ipsec from scratch. 
Attach FAST-IPSEC statistics with 64-bit counters to new sysctl MIB.
Rework netstat to show FAST_IPSEC statistics, via sysctl,  for
netstat -p ipsec.

New kernel files:
	sys/netipsec/Makefile		(new file; install *_var.h includes)
	sys/netipsec/ipsec_var.h	(new 64-bit mib counter struct)

Changed kernel files:
	sys/Makefile			(recurse into sys/netipsec/)
	sys/netinet/in.h		(fake IP_PROTO name for fast_ipsec
					sysctl subtree.)
	sys/netipsec/ipsec.h		(minimal userspace inclusion)
	sys/netipsec/ipsec_osdep.h	(minimal userspace inclusion)
	sys/netipsec/ipsec_netbsd.c	(redo sysctl subtree from scratch)
	sys/netipsec/key*.c		(fix broken net.key subtree)

	sys/netipsec/ah_var.h		(increase all counters to 64 bits)
	sys/netipsec/esp_var.h		(increase all counters to 64 bits)
	sys/netipsec/ipip_var.h		(increase all counters to 64 bits)
	sys/netipsec/ipcomp_var.h	(increase all counters to 64 bits)

	sys/netipsec/ipsec.c		(add #include netipsec/ipsec_var.h)
	sys/netipsec/ipsec_mbuf.c	(add #include netipsec/ipsec_var.h)
	sys/netipsec/ipsec_output.c	(add #include netipsec/ipsec_var.h)

	sys/netinet/raw_ip.c		(add #include netipsec/ipsec_var.h)
	sys/netinet/tcp_input.c		(add #include netipsec/ipsec_var.h)
	sys/netinet/udp_usrreq.c	(add #include netipsec/ipsec_var.h)

Changes to usr.bin/netstat to print the new fast-ipsec sysctl tree
for "netstat -s -p ipsec":

New file:
	usr.bin/netstat/fast_ipsec.c	(print fast-ipsec counters)

Changed files:
	usr.bin/netstat/Makefile	(add fast_ipsec.c)
	usr.bin/netstat/netstat.h	(declarations for fast_ipsec.c)
	usr.bin/netstat/main.c		(call KAME-vs-fast-ipsec dispatcher)

matt 65e5548a17 Add MBUFTRACE kernel option. 
Do a little mbuf rework while here.  Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *).  These are not performance critical and making them
call m_get saves considerable space.  Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.

thorpej 22afdc2c33 Update for the changes to struct ifnet. While I'm here, fix a couple 
of long-standing bugs:

	- Actually deal with the fact that the kernel ifnet list is
	  a TAILQ; it just happened to work before.

	- Use kvm_openfiles() instead of kvm_open().  The code passed
	  arguments to kvm_open() as if it were kvm_openfiles(), but
	  apparently went unnoticed since the prototypes are the same.
	  Amusing bit: there were XXX's in the code which seemed to
	  apologize for a verbose libkvm, when it happened to be a
	  bug in netstat!
