* Improve usability of head(1) and tail(1):Xin LI2022-07-1310-30/+173

* sockstat(1): print PID adjusted to the rightGleb Smirnoff2022-07-071-1/+1
| | | | | | | | This allows for easy copy-and-paste of a unix(4) peer name for lookup. With current implementation it is guaranteed that a peer listed could be found in the output. Differential revision: https://reviews.freebsd.org/D35727
* sockstat(1): print out full connection graph for unix(4) socketsGleb Smirnoff2022-07-072-34/+110
| | | | | | | | | | | | | | | | | | Kernel provides us with enough information to display all possible connections between UNIX sockets. o Store unp_conn, xu_firstref and xu_nextref in the faddr of a UNIX sock. o Build tree of file descriptors, indexed by the socket pointer. o In displaysock() print out all possible information: 1) if socket is bound, print name of this socket 2) if socket has connected to a peer with a name, print peers name 3) if socket has connected to a peer without a name, print [pid fd] 4) if a bound socket has received connections, print list of them as [pid fd] Previously, only 1) either 2) were printed.

* sockstat(1): use tree(3) rbtree instead of hashGleb Smirnoff2022-07-071-48/+57
| | | | | | | | | | | | o Use tree to lookup by socket kvaddr. The size of hash is too big for a small virtual machine and at the same time too little for a large production server. A tree would better fit here. o For those pcbs, that don't have a socket associated, use a list. o Provide a second tree to lookup by pcb kvaddr. These removes full hash traversal when printing every unix(4) socket. Reviewed by: tuexen Differential revision: https://reviews.freebsd.org/D35724

* netstat -i: do not truncate interface namesMike Karels2022-07-062-14/+20
| | | | | | | | | | | | | | | | | The field for interface names for netstat -i was 5 characters by default, which is no longer sufficient with names like "vlan1234" and "vtnet0". netstat -iW computed the necessary field width, but also enlarged the address field by a lot (especially with IPv6 enabled). Make netstat -i compute the field width for interface names with or without -W. Note that the existing default output does not fit in 80 columns in any case. Update the man page accordingly, documenting the remaining effect of -W with -i. Also add -W to the list of General Options, as there are numerous pointers to this.

* mixer: remove volume backwards compat, add % interpretationKyle Evans2022-06-182-8/+8
| | | | | | | | | | | | | | | | The current situation is fairly confusing, where an integer is interpreted as a percent until you slap a decimal on it and magically it becomes an absolute value. Let's have a flag day in 14.0 and remove this shim entirely. Setting with percent can still be useful, so allow a trailing '%' to indicate as such. As a side effect, we tighten down the format allowed in the volume a little bit by ensuring there's no trailing garbage after the value once it's separated into left and right components.

| | | | | | | | | | | | | | | Mbufs leak when manually removing incomplete NDP records with pending packet via ndp -d. It happens because lltable_drop_entry_queue() rely on `la_numheld` counter when dropping NDP entries (lles). It turned out NDP code never increased `la_numheld`, so the actual free never happened. Fix the issue by introducing unified lltable_append_entry_queue(), common for both ARP and NDP code, properly addressing packet queue maintenance.

| | | | | | | | | | | With M_EXTPG mbufs these two counters already do not represent the reality. As we are moving towards protocol independent socket buffers, which may not even use mbufs at all, the counters become less and less relevant. The only userland seeing them was 'netstat -x'.
