Keyword substitution: kv
Default branch: MAIN

Implementation of exFAT filesystem, with compilation conditional on MKEXFATFS
make variable.

use objcopy's --compress-debug-sections when creating debug files.

this reduces the size of the installed files by over half in most cases,
though the debug set size doesn't really change much (which looks like
close to 1GB of space on amd64 with xdebug installed, similar on arm64,
and about 600MB without xdebug.)

tested by running GDB on a few things, seems just as functional, on amd64,
arm64, and slightly on riscv64.

(first attempt for this feature used "gcc -gz=zlib", but that ends up
making CTF unhappy, but fortunately this works in binutils to create
the .debug files separate to any ctf usage of the main file.)

Always use arm-elf2aout; no a.out support both for binutils{,.old}

Fix kernel size inflation for arm and aarch64 (PR toolchain/57146)

For some conditions, SYSTEM_LD_TAIL is set for arm and aarch64.
Then, ctfmerge(1) in default SYSTEM_LD_TAIL is unintentionally
skipped, which results in the catastrophic kernel size inflation,
as reported in the PR.

Also, introduce and use OBJCOPY_STRIPFLAGS variable instead of
STRIPFLAGS, as strip(1) is replaced by objcopy(1) during MI
kernel build procedure.

For Makefile.{arm,aarch64}, weird logic is used to determine how
to handle debug symbols; MKDEBUG{,KERNEL} are taken into account
later in sys/conf/Makefile.kern.inc.

Use OBJCOPY_STRIPFLAGS instead of STRIPFLAGS.
Simplify fix for PR toolchain/57146

Introduce ARCH_STRIP_SYMBOLS variable to centralize logic for debug
symbols from MD Makefile's to Makefile.kern.inc.

adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

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.

sys: document how to run lint on the kernel code (experimental)

sys: Build kernel with -Wno-type-limits.

The type-limits warning is actively harmful because it discourages
writing safe portable overflow detection logic which happens, on some
architectures, to be dead code.

Fix for systems that override SYSTEM_LD_TAIL

use a function "runit" to echo and execute avoiding set -x.

- With DEBUG=-g (which is also set when we build CTF) we build netbsd.gdb *and*
  netbsd-${KERNEL_CONFIG}.debug because it is not worth having two sets of
  rules (one that builds just netbsd.gdb and one that builds both netbsd.gdb
  and netbsd-${KERNEL_CONFIG}.debug. This maintains compatibility building
  netbsd.gdb when DEBUG=-g
- When either MKDEBUGKERNEL=yes or MKDEBUG=tes we set DEBUG=-g if DEBUG was
  not set.
- We only make a debuginstall rule to install netbsd-${KERNEL_CONFIG}.debug
  if MKDEBUG=yes

forgot one KERNEL_BUILD (Tobias Nygren)

Use the tail of KERNEL_BUILD since it can be a full path.

Add ${_MKTARGET_INSTALL}

use ${INSTALL_FILE} so that unpriv builds work.

Enable split-debug files for kernels. Enabled by default with MKDEBUG=yes.

Rename:
    MKKDEBUG -> MKDEBUGKERNEL
    MKTOOLSDEBUG -> MKDEBUGTOOLS
while keeping compatibility with the old names. Add missing documentation.
Now all debugging tunables are prefixed with MKDEBUG.

revert previous: http://mail-index.netbsd.org/source-changes/2021/10/25/msg133295.html

going to add __always_inline to the functions called from _mcount()
discussed on http://mail-index.netbsd.org/source-changes-d/2021/10/25/msg013480.html

In some arch, _mcount() would be called recursively when built with COPTS=-O0.

Normally, functions called from mcount.c are expected to be expanded inline,
so _mcount() will never be called recursively. But when build with COPTS=-O0,
`static inline' functions aren't inlined, and _mcount() will be called
recursively.

Even if _mcount() has `__attribute__((__no_ instrument_function__))',
it has no effect on the calling external (no-inlined) function.

To avoid this, PROF.<fn> is added can be set the profiling flag of any file.
"PROF.mcount.c" is set to blank by default, mcount.c itself is compiled
without -pg.

Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.

Sync w/ HEAD.

sync with head

drm2: build with -fwrapv, since the Linux kernel does and we don't
want to spend too much time fixing their code. silences a lot of
KUBSAN warnings.

we need to use COPTS to have per-option compiler flags. help from
Riastradh.

Sync with HEAD.

Revert rev 1.278 which tried to call ctfmerge only once - this has
caused kernels with embedded symbol tables to explode in size.

Don't use /usr/bin/time (it is not portable)

Move the ctfmerge call from SYSTEM_LD_TAIL (used by both STAGE1 and STAGE2)
to SYSTEM_LD_TAIL_STAGE2 only.  ctfmerge is slow enough that just calling
it once is enough.

sys/conf: remove useless dollars from Makefile.kern.inc

When parsing a variable modifier such as :C or :S, all '$' but the very
last are silently swallowed.

See usr.bin/make/unit-tests/varmod-subst.mk for details.

Since August 2020, make has a strict lint mode that is activated by
passing it the option -dL.  In that mode, these redundant '$' are not
accepted anymore.

add support for new GCC 9 warnings that may be too much to fix
right now.  new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree.  mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it.  (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.)  clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

enable -Walloca, warn if something uses alloca()

enable gcc stack usage limit for kernel functions, set to 3.5 KiB for now
as that seems to be enough to accomodate the current biggest stack usages

there are about six functions which use over 3KiB local stack, and
about a dozen between 2-3 KiB, so pushing this further needs more work
if desired

compile tested on amd64, i386, sparc64, sparc, powerpc (evbppc - BookE),
m68k (mac68k)

Use -fstack-usage only if we are using gcc.

Pointed out by maxv@

Discard -fstack-usage for vax, for which GCC does not support that option
at the moment.

Add -fstack-usage to kernel builds. Produces .su files that can be
analysed to find large stack users.

Do the chmod last so that the kernels get consistent permissions for MKREPRO

Merge changes from current as of 20200406

Infrastructure for putting kernel+modules in /netbsd/kernel and
/netbsd/modules respectively instead of /netbsd and
/stand/<arch>/<version>/modules.  This is only supported for x86,
and is turned off by default. To try it, add KERNEL_DIR=yes in your
/mk.conf and install a system from that build.

pass -Wno-error=implicit-fallthrough for zlib.c.

XXX: consider using copts.mk for various warning/copt flags passed
in kernel builds currently set via 'makeoptions' in files.* files.
this is suboptimal, as those all get embedded into the kernel with
config_file.h.

Merge the [pgoyette-compat] branch

Ssync with HEAD

- Determine KERN_AS automatically depending on whether OPT_MODULAR is
  set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

OK christos

Sync with HEAD

Resolve a couple of conflicts (result of the uimin/uimax changes)

Add CFLAGS, CPPFLAGS, and CWARNFLAGS from options to .c files.

No longer build the libcompat.o which ends up including most of the
compat_netbsd code without creating the module entry that other
modules are depending on, which in turn causes the modules to fail
to load because of redefined symbols.

Restrict -fno-delete-null-pointer-checks to GCC.

use -fno-delete-null-pointer-checks for kernels.

- Coverity does not like -std=gnu99
- Another lose is that you need to manually edit the compiler XML to add
  all the kernel options because cov-configure barfs because it tries to
  test the compilation environment thinking that we are userland even
  when options like -ffreestanding are present.

We use .BEGIN for our own cleanup and won't ever need DTS support - so
avoid inclusion of dts.mk by defining _SKIP_DTS

Allow MD to link libraries.  Build rules are written in MD makefiles until

Add generated *.c files (devsw.c and ioconf.c) to ${CFILES} by config(1)

Prepare for relative ${MD_OBJS}.

Move `all' target definition to Makefile.kern.inc.

Clean up `swap<kernel>.o' handling.

Define ${OBJS} in `Makefile.kern.inc'.  Relative paths are not truncated

Output relative path for ${CFILES} and ${SFILES} in generated `Makefile'.

Add swap<kernel>.o to common ${SYSTEM_LD} as it is always linked.

Clean up some rules and make them less error prone.

Define suffix rules at the end to override system definitions.  Provide them

Experimental suffix-rules build (disabled by default).

Fix "Define compile rules in sys/conf/Makefile.kern.inc ...".

Use `.if !commands(xxx)' to check if `xxx' has a defined, overriden rule,
instead of `.if !targets(xxx)'.  The latter evaluates as true even when `xxx'
has an empty rule to define a dependency.

A makeoptions `DEFWARNINGS', forcibly disabling all ${CC} warnings, is only
used by hpcmips's NULLCONF, which doesn't even build for other causes.

If some source doen't build and needs a workaround, that should be deal with
by modifying per-file ${CC} options (e.g. COPTS.foo.c+=-fno-xxx).  Let's not
use DEFWARNINGS any longer.

Move splash logic, keep Makefile.kern.inc clean.

Put back MEMORY_DISK_IMAGE logic, but use generated opt_memory_root_image.h
and don't polute Makefile.kern.inc.

Define compile rules in sys/conf/Makefile.kern.inc except those overriden by
"file ... compile-with ...".  As rules are still explicit, be careful to not
override by checking .if !target(xxx.o).

Use makeoptions_COPY_SYMTAB via opt_copy_symtab.h in sources.  Remove a hack
to set -DCOPY_SYMTAB from sys/conf/Makefile.kern.inc.  Remove unnecessary
dependencies too.

Move less important part out of Makefile.kern.inc.

Define two suffix rules, .c -> .o and .S -> .o, using ${NORMAL_C} and
${NORMAL_S} respectively.  Use the .c rule to build devsw.c, ioconf.c, and
param.c.  Other .c/.S files have explicit rules in the generated `Makefile',
and unaffected.

Now that MAXUSERS is in opt_param.h, param.o doesn't depend on Makefile.

According to nxr.netbsd.org, nothing uses MEMORY_DISK_IMAGE.  Retire it.
Premature design and its build rule bloats Makefile.kern.inc.  There are
other ways like MEMORY_DISK_DYNAMIC.

(When kernel will be built as relocatable, embedding binary data will be much
easier, and md(4), splash(4), and ksyms(4) will all benefit.)

genassym.cf and machdep.c are _KERNEL_OPT'ed, don't depend on Makefile.

conf.c doesn't exist.

autoconf.c exists, but it's just a C file, no need to depend on Makefile.

I don't see how uipc_proto.c can change its content by Makefile, don't depend
on Makefile.  vfs_conf.c doesn't even exist, remove it too.

Convert MAXUSERS, take 2.

Define MAXUSERS in opt_param.h and include it from sys/param.h, for more
accurate dependency.  Don't define -DMAXUSERS and add it to ${CPPFLAGS}.
config(5)'s "maxusers" syntax doesn't change.

(The version just before revert was OK, but I had something bad in my obj
dirs.)

Revert MAXUSERS changes.  Need fresh air.

Define MAXUXERS in opt_param.h.  Bump config(1) version.

Comment.

Define some suffix rules.  Not used and harmless, because all rules are
explicit now.

Specify explicit output (-o) to ${LINT} too.

Specifiy explicit output (-o) to ${CC}.

netbsd depends on $S/kern/kern_ksyms_buf.c; rarely updated but better safe.

Tweak previous.

Echo exact objects (swap*.o etc.) when linking kernel.

Have MI genassym.cf.

Don't allow MD to override the assym.h generation rule.

(Nothing defines it except i386/bioscall/Makefile, but it is not part of
kernel build.)

Make <kernel>.ldscript ready to include assym.h.

Redo Rev. 1.188:
o Explicitly add dependency of `<kernel>' on `<kernel>.ldscript', instead of
  relying on ${SYSTEM_DEP}, which is evaluated much earlier than
  `sys/conf/Makefile.kern.inc' is included, to avoid evaluation ordering
  problems.
o Print a message when creating a `<kernel>.ldscript'.
o Trim empty lines in `<kernel>.ldscript'.

Fix the build: provide compatibility with ports that define KERNLDSCRIPT to
a file?

If a kernel linker script is provided, preprocess it by cpp(1).

Thus some constants (PAGE_SIZE, COHERENCY_UNIT, ...) can be replaced in linker
scripts without setting unnecessary temporary symbols, or doing ugly sed(1)
hacks.  No headers are included yet.

Fix vers.o dependency:
o Depend on ${SYSTEM_OBJ} instead of ${SYSTEM_DEP}.  The latter is obviously
  meant for kernels.
o Depend on Makefile instead of ${SYSTEM_SWAP_DEP}, which has existed since
  Rev. 1.1, but seems not used now.  Makefile is a file that must be updated
  after every config(1) run.  This is simpler than dependency on swap<kernel>.c.

Define ${LINKSCRIPT} in one place.

If MD ldscript is generated, give it dependency on ${SYSTEM_OBJ}.

Reorganize symbol table embedding.  The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

In file_exists_exact(), fix an incorrect test of "1" instead of "$1",
and improve the comment explaining what this function does.
As long as we don't yet have a working TOOL_GREP, fgrep is more portablethan grep -F.

Unbreak ssp kernels. The issue here that when the ssp_init() call was
deferred, it caused the return from the enclosing function to break, as
well as the ssp return on i386. To fix both issues, split configure in
two pieces the one before calling ssp_init and the one after, and move
the ssp_init() call back in main. Put ssp_init() in its own file, and
compile this new file with -fno-stack-protector. Tested on amd64.
XXX: If we want to have ssp kernels working on 5.0, this change needs to
be pulled up.

Add a stub file that includes a bunch of kernel headers and always get
compiled with -g. For the initial set, netbsd on amd64 grows by around
80KB. This allows much easier use of GDB for post-mortem debugging as
it can understand the layout of data structures. The additional data can
be strip(1)ped off normally for size constraint environments.

Remove unnecessary references to config_time.h.

Use BUILDSYMLINKS from <bsd.files.mk> instead of custom copy rules

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.

If we are going to run mkdep separately for each file, we might as well

However we do need to do something to stop the 'mkdep -d' and CLEANDEPEND
command lines being to long.
Note that 'echo ${xxx} | cmd' is ok because echo is a shell builtin, and
isn't (usually) subject to the kernel's command line limits.
