These programs parse ND6 Router Advertisement messages; rtsold(8) has
required an SA, SA-14:20.rtsold, for a bug in this code. Thus, they
are good candidates for sandboxing.
The approach taken is to run the main executable in capability mode
and use Casper services to provide functionality that cannot be
implemented within the sandbox. In particular, several custom services
were required.
- A Casper service is used to send Router Solicitation messages on a
raw ICMP6 socket. Initially I took the approach of creating a
socket for each interface upon startup, and connect(2)ing it to
the all-routers multicast group for the interface. This permits
the use of sendmsg(2) in capability mode, but only works if the
interface's link is up when rtsol(d) starts. So, instead, the
rtsold.sendmsg service is used to transmit RS messages on behalf
of the main process. One could alternately define a service
which simply creates and connects a socket for each destination
address, and returns the socket to the sandboxed process. However,
to implement rtsold's -m option we also need to read the ND6 default
router list, and this cannot be done in capability mode.
- rtsold may execute resolvconf(8) in response to RDNSS and DNSSL
options in received RA messages. A Casper service is used to
fork and exec resolvconf(8), and to reap the child process.
- A service is used to determine whether a given interface's
link-local address is useable (i.e., not duplicated or undergoing
DAD). This information is supplied by getifaddrs(3), which reads
a sysctl not available in capability mode. The SIOCGIFCONF socket
ioctl provides equivalent information and can be used in capability
mode, but I decided against it for now because of some limitations
of that interface.
In addition to these new services, cap_syslog(3) is used to send
messages to syslogd.

Many size / length parameters in NVMe are "0's based", meaning, a value
of 0x0 represents 1, 0x1 represents 2, etc.. While this leads to an
efficient encoding, it can lead to subtle bugs. With respect to queues,
these parameters include:
- Maximum number of queue entries
- Maximum number of queues
- Number of Completion Queues
- Number of Submission Queues
To be consistent, convert all 0's based values from the host to 1's
based value internally. Likewise, covert internal 1's based values to
0's based values when returned to the host. This fixes an off-by-one bug
when creating IO queues and simplifies some of the code. Note that this
bug is masked by another bug.
While in the neighborhood,
- fix an erroneous queue ID check (checking CQ count when deleting SQ)
- check for queue ID of 0x0 in a few places where this is illegal
- clean up the Set Features, Number of Queues command and check for
illegal values

the value changes, then the latest value is used and an informative message

Currently, this is only a possibility for cpu types, MAXUSERS, and
MACHINE_ARCH. Anything else duplicated in a config file will use the first
value set and error about duplicated options on subsequent appearances,
which is arguably unfriendly since one could specify:
include GENERIC
nooptions VERBOSE_SYSINIT
options VERBOSE_SYSINIT

superblock has a check-hash error, an error message noting the
superblock check-hash failure is printed and the mount fails. The
administrator then runs fsck to repair the filesystem and when
successful, the filesystem can once again be mounted.
This approach fails if the filesystem in question is a root filesystem
from which you are trying to boot. Here, the loader fails when trying
to access the filesystem to get the kernel to boot. So it is necessary
to allow the loader to ignore the superblock check-hash error and make
a best effort to read the kernel. The filesystem may be suffiently
corrupted that the read attempt fails, but there is no harm in trying
since the loader makes no attempt to write to the filesystem.
Once the kernel is loaded and starts to run, it attempts to mount its
root filesystem. Once again, failure means that it breaks to its prompt
to ask where to get its root filesystem. Unless you have an alternate
root filesystem, you are stuck.
Since the root filesystem is initially mounted read-only, it is
safe to make an attempt to mount the root filesystem with the failed
superblock check-hash. Thus, when asked to mount a root filesystem
with a failed superblock check-hash, the kernel prints a warning
message that the root filesystem superblock check-hash needs repair,
but notes that it is ignoring the error and proceeding. It does
mark the filesystem as needing an fsck which prevents it from being
enabled for writing until fsck has been run on it. The net effect
is that the reboot fails to single user, but at least at that point
the administrator has the tools at hand to fix the problem.
