{usr.,}{s,}bin: replace LINT_SUPPORTED with the standard NOLINT

While here, re-enable lint in those cases where lint was skipped due to
a bug in interpreting abstract types, which was fixed in cgram.y 1.469
from 2023-08-02.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

usr.bin: enable lint checks for most programs in /usr/bin

Previously, lint was only activated for the libraries, but not for the
kernel or userland programs. Activate lint for the programs in /usr/bin
for now, more will follow later.

This only affects builds that set MKLINT=yes.

Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

WFORMAT is no more...

Implement MKDYNAMICROOT, which currently defaults to "no", but will
be changed in the future to "yes".

If MKDYNAMICROOT == "no", there is no change from existing behaviour
of a static /bin and /sbin (and a few programs in elsewhere).

If MKDYNAMICROOT == "yes", the following changes occur:
in <bsd.own.mk>:
SHLIBDIR?= /lib
SHLINKDIR?= /lib
in various Makefiles, the following entry is DISABLED.
LDSTATIC?=-static
This results in all programs (except those "standalone" programs built
in sys/arch/*/stand) are linked dynamically, the shared linker is moved
from /usr/libexec to /lib (with a compat symlink), and the shared
libraries used by /bin and /sbin programs are moved from /usr/lib to
/lib (with compat symlinks).

surely not save the situation, not help to recover from it

Allow code to include either (or both) of <sys/elfdefinitions.h> and
<sys/exec_elf.h>, in any order.

This is a work-around to address PR lib/59564 (build breakage when
both of these files are #included).

With this changeset, whichever file gets included first 'wins'.
Prior changes in NetBSD and upstream at Elftoolchain have aligned the
'generic' ELF definitions in NetBSD's <sys/exec_elf.h> with those
in Elftoolchain's <sys/elfdefinitions.h>, so that either file can
be used interchangeably when building NetBSD.

This changeset also removes prior workarounds in the source tree
for this issue.

PR lib/59564

elftoolchain: Be consistent about which ELF header files we use.

1. For tools that use elftoolchain: always use elftoolchain's
elfdefinitions.h. Don't even think about looking at the host's
sys/exec_elf.h, which makes no sense and should never happen.

(ELF tools that don't use elftoolchain, like m68k-elf2coff,
continue to use nbincludes/sys/exec_elf.h. But no more nbincludes
hacks in elftoolchain.)

2. For kernel components (solaris, zfs, dtrace): always use
sys/exec_elf.h, even in Solaris components via sys/elf.h.
elfdefinitions.h is not wired up in the kernel build at all.

3. For most userland components that involve libelf: use
elfdefinitions.h via libelf header files (libelf.h, gelf.h).

libdtrace in particular requires _all_ R_* reloc type definitions,
but sys/exec_elf.h brings in only the _current machine's_ R_*
reloc type definitions. (While here: Use uintptr_t instead of
Elf_Addr for pointer-to-integer cast, since Elf_Addr is MD and
provided only by sys/exec_elf.h, not by elfdefinitions.h.)

And most userland components using libelf don't rely on any
properties of the current machine from sys/exec_elf.h, so they can
use libelf's elfdefinition.h.

Exceptions:

- dtrace drti.c relies on link.h -> link_elf.h -> sys/exec_elf.h,
but it also relies on sys/dtrace.h -> sys/elf.h ->
elfdefinitions.h like other userland components using sys/elf.h.

- kdump-ioctl.c uses sys/exec_elf.h directly and sys/dtrace.h ->
sys/elf.h -> elfdefinitions like other userland components using
sys/elf.h.

- t_ptrace_wait.c (via t_ptrace_core_wait.h) uses libelf to parse
core files, but relies on sys/exec_elf.h for struct
netbsd_elfcore_procinfo.

None of these exceptions needs all R_* reloc type definitions, so
as a workaround, we can just suppress libelf's elfdefinitions.h by
defining _SYS_ELFDEFINITIONS_H_ and use sys/exec_elf.h in these
exceptions.

And undo the whole BUILTIN_ELF_HEADERS mistake. This was:

- half bogus workarounds for missing build_install dependencies in
tools/Makefile, which are no longer missing now, and
- half futile attempt to use src/sys/sys/exec_elf.h via nbincludes in
tools involving libelf instead of libelf's elfdefinitions.h, which
collides.

Longer-term, we may wish to unify sys/exec_elf.h and libelf's
elfdefinitions.h, so we don't have to play these games.

But at least now the games are limited to three .c files (one of
which is generated by Makefile.ioctl-c), rather than haphazardly
applied tree-wide by monstrous kludges in widely used .h files with
broken hackarounds to get the tools build lurching to completion.

updates for libdrm 2.4.114.

unfortunately, the i915 ioctls are no longer handled by kdump/ktruss
as the new one conflicts with base. this needs a clean build in these
dirs (and rescue). the radeon ioctls have been enabled instead.

NPF: Major rework -- migrate NPF to the libnv library.
- This conversion significantly simplifies the code and moves NPF to
a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
previous versions. Also, different serialisation format means NPF
connection/config saving and loading is not compatible with the
previous versions either.

kdump now displays Mach services names itself, including a table of
id/names in sys/compat/mach/mach_services_names.c

Remove ports and flags displays, the information is already in the message.

Fix printf botch

improve formatting in the non-siginfo case, by printing the code. This is
for compatibility with the old ktrace files.

Print siginfo_t information when available.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Grok KTR_EXEC_ENV and KTR_EXEC_ARG.
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-' (remove following) to valid -t arguments.
Dump data block of UNKNOWN trace points in hex + ascii.
Make first time output with -R 0 (instead of time since epoch).
Use svis() instead of vis() to get " escaped (as \") (needs fixed libc)
Correctly pass unsigned values to svis()
Update man pages.

Change back to print hex bytes. The 'word' print was completely broken
on little endian systems. It is also much easier to read misaligned
words in a straight byte hexdump.
Cut offset to 3 hex digits so that it fixs in 80 columns and still
leaves a tab at the start of 'continuation' lines.
The ktrace buffer is limited to 4k, so 3 digits is ample.

On some ports, pointer differences are not ints, so do a cast
before using such a result as a field width.

Make hexdump output fix in 80 char-wide terminal

Use the same code to display hexdump of GIO and MMSG (Mach Messages).
While we are there, display offsets in the hexdump, it can be useful.
Remove size display in Mach Messages as user processes don't always
fill it correctly.

Add -x to usage output.

Add a '-x' option to display GIO data blocks in hex and ascii (instead of
vis(3) format).
Maybe there could be a heuristic to decide whether the data is printable...

Back out previous.

Since a caddr_t is (mis-)used as the lwp-id, cast it to intptr_t and use
apropriate format string.

add appropriate hack to display ktr_buf as the lwpid if -L is supplied on
the command line.

Print rval[1] if non-zero and present in the trace entry.
To get both fd numbers for pipe().

Make "-m0" print no data, so that we agree better with the man page.

Added support for dumping mach messages in ktrace/kdump. While we are
there, KNFify a few functions.

Sync usage with man page (and actual options).

signame(): if sig == 0, return name " 0", so that the result would be
printed as:
CALL kill(0x1e4, SIG 0)
rathern than previous
CALL kill(0x1e4, SIG*unknown 0*)

Add -N which inhibits translation of system calls numbers into names.

Now properly display Mach traps

Allow passing of the ktrace file as the last argument without a -f.

Fix formatting of ktr_user entries so that values of individual bytes
of ktrace record are treated as unsigned char, and printed using "%02x".
Change suggested in bin/17832 by Paul Goyette.

It's easy for ktrace can generate trace files that contain data from
multiple processes, so let's add a "-p pid" option to kdump so that it
can pull out the data for one process easily.

Fix translation in the native emulation. Noted by veego.

Provide hooks for signal number to name translation, and use them for kill
and PSIG.

XXX[1]: This shows that signal emulation ktrace is slightly busted: posted
signals should really be translated to the emulated ones instead of
producing ktrace records with the signal numbers of the native
emulation.
XXX[2]: There are other places where signal names can be displayed, but this
is not done yet.

reverse the notion of fancy, use plain, and increment it so that we can
have multiple levels of plainness. I want to be able to display syscalls
numerically, for that use -nn. This is not documented as it is an wip.

Cosmetic fix so that RET record after CALL execve get the appropriate syscall
even if the emulation changed

Prevent "kdump" from causing a segmentation fault if the io buffer that

put setemul(), ectx_* & appropriate structures to separate file, to make it
more easily sharable with ktruss(1)

Keep track of what pid uses which emulation and ensure proper
structures are used when decoding the ktrace records. This makes
kdump of ktrace -i output of a process executing binaries of various
emulations actually useful - before, the code used emulation structures
appropriate for last recently executed process, which is bogus.

Cast timeval members to types we know the printf conversions of.

NPF: Major rework -- migrate NPF to the libnv library.
- This conversion significantly simplifies the code and moves NPF to
a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
previous versions. Also, different serialisation format means NPF
connection/config saving and loading is not compatible with the
previous versions either.

- instead of hard-coding the include paths in mkioctls, pass them in

Okay dogcow@.

deal with VERIEXEC_LOAD/SPKRTONE conflict

Provide a dummy default for NBPG after including <sys/param.h> to deal
with a build problem for sparc. The reason is that <dev/tc/sticio.h>
(yes, irrelevant for sparc...) wants NBPG declared, but for sparc user-land
that symbol is not available since sun4/sun4c/sun4m do not all share the
same page size.

Add one more conflicting ioctl set: CLOCKCTL_ADJTIME / TCTRL_MODEM_PWR,
(partially) fixes build problem for sparc.

Add handling of two more pairs of duplicate ioctl values: amiga's

'${CC:-cc} -E' rather than 'cpp': want to use a cross-compiler if

ectx_find() failed to lookup the emulation context unless it happened

default emulation on every EMUL trace record

rewrite ectx_find() to fix this, using <sys/queue.h> LIST for readability

this fix should once and for all remove need to ever use -e option,
and makes kdump work properly for traces with processes under different
emulations

- add a new flags field to the emulation vector, with one user so far
EMUL_FLAG_NETBSD32. set EMUL_FLAG_NETBSD32 in any 32 bit on 64 bit
kernel emulation layers.
- if EMUL_FLAG_NETBSD32 is set, calculate the proper argument count.
(XXX: this should use register32_t, but that's not visible to all
builders of kdump...)

now netbsd32_ioctl(2) actually reports sane values, and other arguments
are mostly correctly printed (there are still some signed extension
issues with 32 bit numbers being displayed as "0xffffffff8xxxxxxx".)

Stop core dump if an ioctl trace has fewer than expected arguments.
- Check names of system calls (for special treatment) because emulations
might use different numbers.
- Report an error if arguments to -p or -m non-numeric.
- Just take last of -x and -Xvalue, stop -X0x80000000 being valid (core dumps).
- Keep 'last used' emulation_ctx at top of list, create on lookup (usually
EMUL anyway), delete when exit called (doesn't return).
- Slightly improve hack to get correct system call name in execve return
when emulation has changed.
- Rename global variables 'current'/'previous' to 'cur_emul'/'prev_emul'.
