2020-07-18oops - the description of -i had a similarly incorrect text as -I concerningJason McIntyre
use of -f; remove that too; pointed out by guenther
2020-07-18the text describing the effect of -f on -I is apparently wrong - no such codeJason McIntyre
was ever added; the text was added 21 years ago when ip6 support was added; marfabastewart noticed it, and guenther tracked down the commit responsible; this commit removes that text;
2020-06-16rework SYNOPSIS/usage() to show better the various use formats,Jason McIntyre
and rework the man text to reflect this; guenther supplied the details on the various modes; deraadt suggested __progname be banished from usage();

2020-06-12Add -R to show a summary of rdomains with associated interfaces and tables.remi
My first version also displayed the number of routes per table. But duming all routing tables to count the entries in userland is expensive. Once the kernel can export these counters the numbers can be added to the output of -R. OK benno@ previous version OK sthen@

2019-12-08Make sure packet destination address matches interface address,Alexandr Nedvedicky
where such packet is bound to. This check is enforced if and only IP forwarding is disabled. Change discussed with bluhm@, claudio@, deraadt@, markus@, tobhe@ OK bluhm@, claudio@, tobhe@

2019-07-16Prevent integer overflow in kernel and userland when checking mbufAlexander Bluhm
limits. Convert kernel variables and calculations for mbuf memory into long to allow larger values on 64 bit machines. Put a range check into the kernel sysctl. For the interface itself int is still sufficient. In netstat -m cast all multiplications to unsigned long to hold the product of two unsigned int. input and OK visa@

2019-06-28When system calls indicate an error they return -1, not some arbitraryTheo de Raadt
value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.
2019-06-13Do memory size calculations as unsigned long. OtherwiseAlexander Bluhm
netstat -m would print the result of a signed interger overflow if kern.maxclusters is 1048576 or above. OK claudio@

errors include these, do not subtract both from delivered. Avoids an underflow in the rip6 delivered counter. OK deraadt@ claudio@

2019-04-17remove some unneccessary baggage: Nm does not require an argument,Jason McIntyre
and the Bk/Ek invocation here is no longer neccessary;
2019-03-05add -e to usage; while here, change the argument name to -T from tableidJason McIntyre
to rtable, to match the man page;
2019-03-04when showing interface stats, combine the queue drops with errors as failsDavid Gwynne
if you want to see errors or queue drops on their own, use -e or -d respectively. ok claudio@ deraadt@

This is a preliminary step for using percpu counters with the data. OK mpi@
2017-10-28Bring "netstat -m" output up to speed with the kernelMike Belopuhov
The kernel no longer sets watermarks on cluster pools rendering "max" values useless. Instead, there's now a global limit on how much memory all cluster pools combined together can allocate from the system. The limit is set to kern.maxclusters number of 2Kb increments which allows us to display current, peak and maximum total memory used by the network. OK claudio, millert
2017-10-25Remove the TCP_FACK option and associated #if{,n}def code.job
TCP_FACK was disabled by provos@ in June 1999. TCP_FACK is an algorithm that decides that when something is lost, all not SACKed packets until the most forward SACK are lost. It may be a correct estimate, if network does not reorder packets. OK visa@ mpi@ mikeb@

2017-07-27uint32_t is never < 0; pointed out by clang.Florian Obser
While we originally get a short passed from the kernel, it's probably better for debugging purposes to show what we are actually having which is a uin32_t hence the %u format. OK deraadt
