824e1afcf8 Ensure libregex is built in time for googletest
In lib/Makefile, we document the dependency with SUBDIR_DEPEND

For buildworld orchestration, just prebuild libregex if GOOGLETEST is
enabled. googletest will get built in a later pass.

1813ea62e3 bsdgrep: switch to libregex for GNU_GREP_COMPAT
libregex is incomplete, but it's a bit less buggy than the in-base
libgnuregex and mostly OK.

While here, rename -DIWTH_GNU -> -DWITH_GNU_COMPAT; the option implies
that we're compatible with the GNU counterpart, not that we're including GNU
anything.

ff4a53125e gtest: link against libregex for GNU extensions

dbec43ffa6 libregex: Implement a subset of the GNU extensions
The entire patch-set is not yet mature enough for commit, but this usable
subset is generally enough for googletest to be happy with and mostly map to
some existing concepts, so they're not as invasive.

The specific changes included here are:

- Branching in BREs with \|
- \w and \W for [[:alnum:]] and [^[:alnum:]] respectively
- \s and \S for [[:space:]] and [^[:space:]] respectively
- Additional quantifiers in BREs, \? and \+ (self-explanatory)

There's some #ifdef'd out work for allowing empty branches as a match-all.
This is a feature that's under assessment... future work will determine
how standard this behavior is and act accordingly.

f2908d16c3 Allow building setmode.c on Linux/macOS
We bootstrap this file to allow compiling FreeBSD on Linux systems since
some boostrap tools use setmode(). Unfortunately, glibc's sys/stat.h
declares a non-static getumask() function (which is unimplemented!) and
that conflicts with the local getumask() function. To work around this
simply use a different name here.

9664ec9805 Pass the full CFLAGS to cpp for MKlib_gen.sh.
GCC's cpp was exiting immediately when it failed to find requested
includes (<ncurses_cfg.h> and <ncurses_defs.h>).  clang-cpp emitted an
error for the missing header files but continued processing the file
(thus not honoring any macros defined in the missing headers).

Arguably, the awk script is buggy since it doesn't check the return
value of the command it executes.

Reduce code duplication when a bus is subclassed from simplebus by allowing
them to call simplebus_attach directly. This is useful when the child bus
will just implement the same calls.

As not all children will expect to have a ranges property, e.g. the

20cc526004 libc: Provide sub fp(s|g)etmask() implementations for RISC-V
RISC-V doesn't support floating-point exceptions.

RISC-V Instruction Set Manual: Volume I: User-Level ISA, 11.2 Floating-Point
Control and Status Register: "As allowed by the standard, we do not support
traps on floating-point exceptions in the base ISA, but instead require
explicit checks of the flags in software. We considered adding branches
controlled directly by the contents of the floating-point accrued exception
flags, but ultimately chose to omit these instructions to keep the ISA simple."

We still need these functions, because some applications (notably Perl) call
them, but we cannot provide a meaningful implementation.

4788f7f17f vt(4): CONS_HISTORY/CONS_CLRHIST should operate on issuing terminal
Currently the CONS_HISTORY and CONS_CLRHIST ioctls modify the state of the
active terminal instead of the terminal against which the ioctl was issued.
Because of the way vidcontrol(1) works, these are the same in most cases.
But a poorly-timed window switch can make them differ. This is reproducible
by issuing e.g. 'vidcontrol -s 2 && vidcontrol -C' to switch from vty 1 to
vty 2; teken will reset the cursor position on vty 1 but vt(4) will clear
the history buffer of vty 2, producing an interesting state of affairs.

d9e2fc360f Fix TX csum handling in if_mvneta
The mvneta device requires MVNETA_TX_CMD_L4_CHECKSUM_NONE bit to be set in the tx descriptor is checksum not required. However, mvneta_tx_set_csumflag() is not setting this flag currently, causing the hardware to randomly corrupt IP header during transmission.

This affects injected IPv4 packets that skips kernel IP stack processing (e.g. DHCP), as well as all IPv6 packets, since the driver currently does not offload csum for IPv6.

The fix is to remove all the early return paths from mvneta_tx_set_csumflag() which do not set the MVNETA_TX_CMD_L4_CHECKSUM_NONE flag.

88dceb1da5 Add optional support for ext_pgs mbufs to the NFS server's read, readlink
and getxattr operations.

This patch optionally enables generation of read, readlink and getxattr replies
in ext_pgs mbufs.  Since neither of ND_EXTPG or ND_TLS are currently ever set,
there is no change in semantics at this time.
It also corrects the message in a couple of panic()s that should never occur.

This is another in the series of commits that add support to the NFS client
and server for building RPC messages in ext_pgs mbufs with anonymous pages.
This is useful so that the entire mbuf list does not need to be
copied before calling sosend() when NFS over TLS is enabled.

Use of ext_pgs mbufs will not be enabled until the kernel RPC is updated
to handle TLS.
