NanoBSD or, more generally, systems with root_rw_mount="NO" are not able
to remove the firstboot_sentinel file, typically /firstboot, because the
logic in /etc/rc is currently inverted.
When checkyesno root_rw_mount tests on a read-only file system, the
return is 1, hence avoiding the option to mount the system read-write.
Restore the ability to remove the firstboot_sentinel file on read-only
mounted file systems.
This change was introduced in 40adda8665, and partially fixed in
1ce07411fa.

PR#254282 reports a problem where nullfs mounts cannot be
exported via mountd for FreeBSD 13.0.
The problem seems to be that, to do the nullfs mounts in
/etc/fstab, they require the "late" mount option, so that the
underlying filesystem is mounted (ZFS for the PR).
Adding "mountlate" to the REQUIRE list in /etc/rc.d/mountd
fixes the problem, but that results in a dependency cycle
because /etc/rc.d/lockd specifies:
REQUIRE: nfsd
BEFORE: DAEMON
--> which forces mountd to preceed DAEMON.
This patch removes "nfsd" from REQUIRE for lockd and statd,
then adds mountlate to REQUIRE for mountd, to fix this
problem. Having lockd REQUIRE nfsd was done in the NetBSD
code when it was pulled into FreeBSD and there does not
seem to be a need for this.
In case this causes problems, a long MFC has been specified.

- Include <machine/tls.h> in MD rtld_machdep.h headers.
- Remove local definitions of TLS_* constants from rtld_machdep.h
headers and libc using the values from <machine/tls.h> instead.
- Use _tcb_set() instead of inlined versions in MD
allocate_initial_tls() routines in rtld. The one exception is amd64
whose _tcb_set() invokes the amd64_set_fsbase ifunc. rtld cannot
use ifuncs, so amd64 inlines the logic to optionally write to fsbase
directly.
- Use _tcb_set() instead of _set_tp() in libc.
- Use '&_tcb_get()->tcb_dtv' instead of _get_tp() in both rtld and libc.
This permits removing _get_tp.c from rtld.
- Use TLS_TCB_SIZE and TLS_TCB_ALIGN with allocate_tls() in MD
allocate_initial_tls() routines in rtld.

A mismerge of a merge to catch up to main resulted in files being

This disables the random (between zero and one seconds) delay before
rtsol and rtsold send a a Router Solicitation packet. This delay is
specified as a SHOULD by RFC 4861 for avoidance of network congestion,
but network speeds have increased enough in the 25 years since this
first appeared (in RFC 1970) that it seems unnecessary as a default
at this point.
This speeds up the FreeBSD boot process by an average of 500 ms.

If fstatfs(2) caused some failure on normal filesystem, then typical

mmap(2) PROT_EXEC on MNT_NOEXEC filesystem returns EACCES.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

PIE and shared objects usually have many relative relocations. In
2017/2018, a compact relative relocation format RELR was proposed on
https://groups.google.com/g/generic-abi/c/bX460iggiKg/m/GxjM0L-PBAAJ
("Proposal for a new section type SHT_RELR") and is a pre-standard.
RELR usually takes 3% or smaller space than R_*_RELATIVE relocations.
The virtual memory size of a mostly statically linked PIE is typically
5~10% smaller.
ld.lld --pack-dyn-relocs=relr emits RELR relocations. DT_RELR has been
adopted by Android bionic, Linux kernel's arm64 port, Chrome OS (patched
glibc).
This patch adds DT_RELR support to FreeBSD rtld-elf.
