This will allow to hook a ddb script to "kdb.enter.trap" event.
Previously there was no specific name for this event, so it could only
be handled by either "kdb.enter.unknown" or "kdb.enter.default" hooks.
Both are very unspecific.
Having a specific event is useful because the fatal trap condition is
very similar to panic but it has an additional property that the current
stack frame is the frame where the trap occurred. So, both a register
dump and a stack bottom dump have additional information that can help
analyze the problem.
I have added the event only on architectures that have trap_fatal()
function defined. I haven't looked at other architectures. Their
maintainers can add support for the event later.
Sample script:
kdb.enter.trap=bt; show reg; x/aS $rsp,20; x/agx $rsp,20

x86 enforces an (arbitray) limit on the number of available MSI and
MSI-X interrupts to simplify code (in particular, interrupt_source[]
is statically sized). This means that an attempt to allocate an MSI
vector needs to fail if it would go beyond the limit, but the checks
for exceeding the limit had an off-by-one error. In the case of MSI-X
which allocates interrupts one at a time this meant that IRQ 768 kept
getting handed out multiple times for msix_alloc() instead of failing
because all MSI IRQs were in use.

ACPI I/O port descriptors use _MIN and _MAX fields to specify the set
of allowable base (start) addresses for an I/O port resource along with
a _LEN field specifying the length. A fixed resource is supposed to be
encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to
the end of the fixed range. Relocating I/O ranges only make sense in
_PRS (possible resource settings), not in _CRS (current resource settings),
so if an I/O port range with _MAX set set to the end of the range is
present in _CRS, treat it as a fixed I/O port resource starting at
_MIN.

fget_cap() tries to do a cheaper snapshot of a file descriptor without
holding the file descriptor lock. This snapshot does not do a deep
copy of the ioctls capability array, but instead uses a different
return value to inform the caller to retry the copy with the lock
held. However, filecaps_copy() was returning 1 to indicate that a
retry was required, and fget_cap() was checking for 0 (actually
'!filecaps_copy()'). As a result, fget_cap() did not do a deep copy
of the ioctls array and just reused the original pointer. This cause
multiple file descriptor entries to think they owned the same pointer
and eventually resulted in duplicate frees.
The only code path that I'm aware of that triggers this is to create a
listen socket that has a restricted list of ioctls and then call
accept() which calls fget_cap() with a valid filecaps structure from
getsock_cap().
To fix, change the return value of filecaps_copy() to return true if
it succeeds in copying the caps and false if it fails because the lock
is required. I find this more intuitive than fixing the caller in
this case. While here, change the return type from 'int' to 'bool'.
Finally, make filecaps_copy() more robust in the failure case by not
copying any of the source filecaps structure over. This avoids the
possibility of leaking a pointer into a structure if a similar future
caller doesn't properly handle the return value from filecaps_copy()
at the expense of one more branch.
I also added a test case that panics before this change and now passes.

- Warn, don't exit, when SIOCSLAGGPORT returns an error.
When we exit with an error during lagg creation, a single
failed NIC (which no longer attaches) can prevent lagg
creation and other configuration, such as adding an IPv4
address, and thus leave a machine unreachable.
- Preserve non-EEXISTS errors for exit status from SIOCSLAGGPORT,
in case scripts are looking for it. Hopefully this can be
extended if other parts of ifconfig can allow a "soft" failure.
- Improve the warning message to mention what lagg and what
