Revert "release: Ship firmware from kmods repo on DVD"
As we did in 14.4, this needs to be backed out of 15.1 to fix the
build. We're going to ship kmods built on 15.0 instead of 15.1 on
the DVD but hopefully those will work.
This reverts commit b0fbed20ceb9b899e7e20bf785e9d303608bc7a0.

fexecve(2): call out a scenario where you want !O_EXEC
We note a reason why you might need it, but there's an equally important
reason you may need to omit it: interpreted programs. Add a note
accordingly, along with the workaround configuration if there's reason
you can't help it.

stat: fix use of devname(3)
Besides being a little hard to parse through visually, this had its own
bug of inspecting st->st_mode to determine what to pass to devname(3),
which is only correct for st_rdev.
For st_dev, you're likely to be looking at files or directories and
attempting to assess what device they're located on, so the mode is
meaningless- we just have to assume that our filesystems are on
character devices and attempt to resolve st_dev as such.

build: provide a FORTIFY_SOURCE.<src file> override
For native files we can do more minimal fixes to avoid this large of a
hammer, but for third party files it may not be worth the effort to try
and patch them. NetBSD has the original _FORTIFY_SOURCE implementation
that ours is based on, for instance, but tests sourced from there can't
do an __ssp_real(foo) without being certain that `foo` actually has a
fortified definition.
This change does always define _FORTIFY_SOURCE as a result, so gate it
on CFLAGS not already containing _FORTIFY_SOURCE definitions.

tests: fix remaining test failures under _FORTIFY_SOURCE
The getgroups test is a NetBSD tests, so just apply our larger hammer

surgical approach and use __ssp_real() appropriately, since it's a local
one.

ssp: fix our gets_s implementation under _FORTIFY_SOURCE
Annex K specifies an interface for handling constraint violations from
gets_s, but we previously broke this for some classes of get_s misuse.
Provide a more nuanced version that tries to dodge errors that would
trigger a constraint handler while still providing value. Notably, we
don't want to trigger a failure unless the passed-in length reasonably
fits within an RSIZE_MAX, because gets_s will immediately call larger
lengths bogus and fail.

krb5: Fix two NegoEx parsing vulnerabilities
Bring in upstream commit 2e75f0d93 fixing two CVEs. Upstream commit
log is:
In parse_nego_message(), check the result of the second call to
vector_base() before dereferencing it. In parse_message(), check for
a short header_len to prevent an integer underflow when calculating
the remaining message length.
Reported by Cem Onat Karagun.
CVE-2026-40355:
In MIT krb5 release 1.18 and later, if an application calls
gss_accept_sec_context() on a system with a NegoEx mechanism
registered in /etc/gss/mech, an unauthenticated remote attacker can
trigger a null pointer dereference, causing the process to terminate.

powerpc/pic: fix the openpic CPU logic to work on powermac
Earlier work (40bcad56f - powerpc/pic: Add a PIC_AP_INIT() to
set up AP PIC info) broke booting my dual G5 powermac.
After much digging, jhibbits@ and I discovered that the openpic
implementation for the memory/bus controller used in the G5 CPUs
doesn't implement /all/ of the openpic specification.
Notably it sticks the WHOAMI register in a different location.
This is reading 0x0 back for all the PICs which is .. very not great.
So to restore the previous behaviour, use a quick for now that jhibbits@
can set appropriately to trust WHOAMI.
I've tested this on my dual G5 PPC and it boots/runs fine.

nfscl: Disable use of callbacks for NFSv4.0
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 client. This is the same behavior as
occurred when the nfscbd(8) daemon was not running.
This change allowed a function called nfscl_getmyip()
to be removed from the kernel, which is nice since
maintaining this function was bothersome, due to its
use of routing, etc.

* Don't iterate over each string three times; once is enough.
* Reject control characters (anything below space) in addition to the

* If an unsafe character is encountered, discard the string instead of

* If backslashes are encountered in the file name option, convert them

* Tweak the warning messages a bit. Looking through the rest of the

warnings generally don't.

md5: Encode non-printable filenames
Encode filenames in the VIS_CSTYLE | VIS_OCTAL style regardless of
output mode. When reading filenames from a checksum file, attempt to
decode them, and use the decoded name unless the decoded name does not
exist but the undecoded one does.
This breaks compatibility with GNU coreutils, which unfortunately uses
a non-reversible encoding when outputting filenames containing
non-printable characters.
While here, drop a sentence about preimage attacks against MD5 and SHA1
from the manual page, as I no longer trust it to be true.
