This enables the use of modules for a significant build performance gain
when building with clang as host compiler or when using HAVE_LLVM=yes.
Switch libc++ to using the copy from the mono-repo.
hierarchy. This is identical to netbsd-GENERIC, except it has been
dbsym'd so that the kernel symbols are available when running under
Qemu (which loads the kernel directly, but does not load the symbol
table).
in order to make both framebuffer and serial consoles happy.
Also, change TERM from vt220 to vt100 for console and constty
in accordance with other ports.
- New /etc/security check for entropy in daily security report.
- New /etc/rc.d/entropy script runs (after random_seed and rndctl) to
check for entropy at boot -- in rc.conf, you can:
. set `entropy=check' to halt multiuser boot and enter single-user
mode if not enough entropy
. set `entropy=wait' to make multiuser boot wait until enough entropy
Default is to always boot without waiting -- and rely on other
channels like security report to alert the operator if there's a
problem.
- New man page entropy(7) discussing the higher-level concepts and
system integration with cross-references.
- New paragraph in afterboot(8) about entropy citing entropy(7) for
more details.
This change addresses many of the issues discussed in security/55659.
This is a first draft; happy to take improvements to the man pages and
scripted messages to improve clarity.
I considered changing motd to include an entropy warning with a
reference to the entropy(7) man page, but it's a little trickier:
- Not sure it's appropriate for all users to see at login rather than
users who have power to affect the entropy estimate (maybe it is,
just haven't decided).
- We only have a mechanism for changing once at boot; the message would
remain until next boot even if an operator adds enough entropy.
- The mechanism isn't really conducive to making a message appear
conditionally from boot to boot.
The output without the dollar sign is less confusing as it's actual
valid shell syntax:
$ /etc/rc.d/foo rcvar
# food
food=YES
Brought up on tech-userlevel@ by Rocky Hotas with some LGTMs from
other people and no objections.
We still refer to '$food' in warnings/errors though.
The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.
- Use "-6" instead of "--noipv4" as it seems more appropriate based on
the dhcpcd(8) manual page.
- Remove "-f /dev/null" as it seems unnecessary with "-6".
- Remove "--persistent" as it is in the default /etc/dhcpcd.conf,
and this way the user can change it, if they would like to (either
through dhcpcd_flags or by editing /etc/dhcpcd.conf).
The "-b" (or "--background") option is needed to avoid a timeout error
message (and a delay in booting), so it is still left in place.
