libsa: Hook getopt.c

Its declaration (as well as `optarg` et al.) is already in stand.h.

Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

We don't want SSP/FORTIFY here.

branches: 1.95.12;
add bi-endian support to the libsa ufs reader and enable it in efiboot.

ffs frontends to "ufs.c" now also define ufs_dinode_swap, ufs_indp_swap,
and FS_MAGIC (moved from ufs.c #if segments.) these are used to call
the right (32/64 bit) ffsv1/v2 version.

ufs.c 'struct file' gains f_swapped member. accessors for d_magic,
d_reclen, and d_ino are introduced (they need to be swapped.) sfter
reading an inode from disk, read_inode() may call ufs_dinode_swap().
indirect block number and caches may be swapped.

error handling in ffs_find_superblock() is cleaned up. (size is slightly
reduced on some ports with this part.)

defaults for new defines added to ufs.c. (XXX: we build ufs.c but i think
all the consumers don't use it, and we can stop building it.)

LFS support is not included.

add a cut-down copy of ffs_bswap.c from the kernel.

also enable bi-endian disklabel support in efiboot.

most ports build and sizes compared for platforms that don't enable this
code and all but one saw reduced code size. booted several platforms with
new boot code.

move bi-endian disklabel support from the kernel and libsa into libkern.

- dkcksum() and dkcksum_sized() move from subr_disk.c and from
libsa into libkern/dkcksum.c (which is missing _sized() version),
using the version from usr.sbin/disklabel.

- swap_disklabel() moves from subr_disk_mbr.c into libkern, now called
disklabel_swap(). (the sh3 version should be updated to use this.)

- DISKLABEL_EI becomes a first-class option with opt_disklabel.h.

- add libkern.h to libsa/disklabel.c.

this enables future work for bi-endian libsa/ufs.c (relevant for ffsv1,
ffsv2, lfsv1, and lfsv2), as well as making it possible for ports not
using subr_disk_mbr.c to include bi-endian disklabel support (which,
afaict, includes any disk on mbr-supporting platforms that do not have
an mbr as well as disklabel.)

builds successsfully on: alpha, i386, amd64, sun2, sun3, evbarm64,
evbarm64-eb, sparc, and sparc64. tested in anita on i386 and sparc,
testing in hardware on evbarm64*.

Unify all arch/*/stand's atoi() to MI libsa.
lib/libsa/atoi.c was separated from lib/libsa/bootcfg.c.
PR/49084

patch posted to tech-kern@ 2014/06/25 for review with minor changes
resulting from feedback.

move multiple copies of code for parsing boot.cfg file from sparc, i386
and zaurus into libsa/bootcfg.{h,c}. largely retained i386 parsing logic
in addition to keeping sparc dispatch function while remaining consistent
with boot.cfg(5).

previous sparc64 file format has been obsoleted but only used by boot
CDs distrib/sparc64/bootfs/boot.cfg has been updated to compensate.

exported names have been prefixed with either BOOTCFG_ or bootcfg_ as per
feedback from christos@

tested on amd64 & sparc64 but not zaurus.

http://mail-index.NetBSD.org/tech-kern/2011/12/17/msg012229.html

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

Build libraries for kernel/standalone code from within their compilation

(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
bad interactions with amd reported in PR bin/7374 (Arne Juul) and
lossage reported by Andrew Gillham ("obj" dirs and relative paths still
don't work well together)

Avoid user space headers for standalone programs.

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will

Another round of clean up, including fixes presented by Matthias Drochner

- all IP addresses are now `struct in_addr's.
- the function rarp_getipaddress() no longer return `myip'; in stead
it returns -1 on failure (errno set), 0 on success. `myip' is set
as a size-effect.

Clear up some size_t/ssize_t confusion.

Correct the padding to min Ethernet packet size.

Changes from Gordon Ross:
a) check against `my' ethernet or broadcast addresses done in
ether.c
b) changed interface to readether() to provide ethertype info
c) respond to arp requests when appropriate.
First two are clean-up. Last fixes hp300 and presumably mvme68k netboot

Remove bcmp(). Use memcmp() instead.

Another attempt to get libsa to contain the right things.
- put a 'standards conforming' memcmp into memcmp.c
- make bcmp be a second label on the same code
- make bcmp.c be just #include "memcmp.c"
This means that libsa.o might contain both a memcmp.o and a bcmp.o, but
both contain the same code (defining both symbols) so it doesn't matter
which ld uses.
Saves worrying about which of bcmp.c and memcmp.c the architecture specific
Makefile requests.

The __strong_alias() seems to have to be in the file with the definition.
So make bcmp.c define bcmp and memcmp.
This should (?) fix the atari build.
(I've now no idea why the previous change defined memcpy for the alpha build.)

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

Make a bunch of backward-compatible changes to the boot blocks which allow

by compiling one of the alpha boot blocks which uses all of the code
before and after, diffing the object files, and manually verifying that
the differences were 'correct'. some differences were "unavoidable,"
it wanting to avoid a double-commit, because e.g. local variables which
were previously used were no longer used.) a README which describes
supported options (or at least the ones mentioned below) is forthcoming.

add support for the preprocessor macro LIBSA_NO_TWIDDLE, which
causes calls to twiddle() to be omitted if it's defined.
add support for the preprocessor macros:
LIBSA_NO_FS_CLOSE
LIBSA_NO_FS_WRITE
LIBSA_NO_FS_SEEK
which, if defined, cause the corresponding file system operations
in the individual file system implementations to be omitted. (note
that all of those macros are not supported by all file systems at
this point. comments were added to individual file system files
to indicate lack of support, and should be cleaned up later. Backward
compatibility options e.g. UFS_NOCLOSE, etc., are supported.)
add support for the preprocessor macro LIBSA_NO_FS_SYMLINK, which
removes support for symbolic links from the file system support
functions. (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_FS_SINGLECOMPONENT which
removes all subdirectory and symlink support from the file system
support functions. (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_NO_FD_CHECKING, which
causes code relating to libsa file descriptor checks (e.g. range
checking and checking that a file descriptor is valid) to be
omitted if it's defined.
add support for the preprocessor macro LIBSA_NO_RAW_ACCESS, which
causes code relating to raw device access to be omitted if it's
defined.
change some structure copies to use bcopy() instead. that way
use of bcopy vs. memcpy() can easily be selected by
LIBSA_USE_MEMCPY. (without changes like these, you could end up
having both bcopy() and memcpy() included. eventually, all
calls to bcopy should be changed to calls to memcpy() or memmove()
as appropriate -- hopefully never the latter -- with an option to
use bcopy instead.)
add support for the preprocessor macro LIBSA_NO_DISKLABEL_MSGS, which
causes disklabel() to return '1' as msg rather than a string. Can
be used if the boot blocks don't care about the string, and need to
save the space.
add support for the preprocessor macro LIBSA_SINGLE_FILESYSTEM, which
if defined causes all of the file system switch code to be removed.
Its value should be the name of the file system supported by the
boot block, e.g. "ufs" for the FFS file system. calls to the
file system functions open, close, etc., which were previously
done through a function switch are then done via direct invocation
of <fs>_open, <fs>_close, etc. (e.g. ufs_open, ...).
add support for the preprocessor macro LIBSA_SINGLE_DEVICE, which
does the equivalent of LIBSA_SINGLE_FILESYSTEM but for the device
switch table. Device entry pointes are expected to be named
<dev>foo, e.g. the 'strategy' routine used when LIBSA_SINGLE_DEVICE
is set to 'disk' is diskstrategy.
make ufs.c f_nindir array be unsigned ints. the fact that it was signed
caused ufs.c to require signed division routines (which were otherwise
unnecessary for a small boot block).

Initial revision

in getdisklabel() swap the other-endian disklabel, #ifdef LIBSA_DISKLABEL_EI

move bi-endian disklabel support from the kernel and libsa into libkern.

- dkcksum() and dkcksum_sized() move from subr_disk.c and from
libsa into libkern/dkcksum.c (which is missing _sized() version),
using the version from usr.sbin/disklabel.

- swap_disklabel() moves from subr_disk_mbr.c into libkern, now called
disklabel_swap(). (the sh3 version should be updated to use this.)

- DISKLABEL_EI becomes a first-class option with opt_disklabel.h.

- add libkern.h to libsa/disklabel.c.

this enables future work for bi-endian libsa/ufs.c (relevant for ffsv1,
ffsv2, lfsv1, and lfsv2), as well as making it possible for ports not
using subr_disk_mbr.c to include bi-endian disklabel support (which,
afaict, includes any disk on mbr-supporting platforms that do not have
an mbr as well as disklabel.)

builds successsfully on: alpha, i386, amd64, sun2, sun3, evbarm64,
evbarm64-eb, sparc, and sparc64. tested in anita on i386 and sparc,
testing in hardware on evbarm64*.

Make a bunch of backward-compatible changes to the boot blocks which allow
size to be reduced substantially. (backward compatibility verified
by compiling one of the alpha boot blocks which uses all of the code
before and after, diffing the object files, and manually verifying that
the differences were 'correct'. some differences were "unavoidable,"
it wanting to avoid a double-commit, because e.g. local variables which
were previously used were no longer used.) a README which describes
supported options (or at least the ones mentioned below) is forthcoming.

add support for the preprocessor macro LIBSA_NO_TWIDDLE, which
causes calls to twiddle() to be omitted if it's defined.
add support for the preprocessor macros:
LIBSA_NO_FS_CLOSE
LIBSA_NO_FS_WRITE
LIBSA_NO_FS_SEEK
which, if defined, cause the corresponding file system operations
in the individual file system implementations to be omitted. (note
that all of those macros are not supported by all file systems at
this point. comments were added to individual file system files
to indicate lack of support, and should be cleaned up later. Backward
compatibility options e.g. UFS_NOCLOSE, etc., are supported.)
add support for the preprocessor macro LIBSA_NO_FS_SYMLINK, which
removes support for symbolic links from the file system support
functions. (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_FS_SINGLECOMPONENT which
removes all subdirectory and symlink support from the file system
support functions. (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_NO_FD_CHECKING, which
causes code relating to libsa file descriptor checks (e.g. range
checking and checking that a file descriptor is valid) to be
omitted if it's defined.
add support for the preprocessor macro LIBSA_NO_RAW_ACCESS, which
causes code relating to raw device access to be omitted if it's
defined.
change some structure copies to use bcopy() instead. that way
use of bcopy vs. memcpy() can easily be selected by
LIBSA_USE_MEMCPY. (without changes like these, you could end up
having both bcopy() and memcpy() included. eventually, all
calls to bcopy should be changed to calls to memcpy() or memmove()
as appropriate -- hopefully never the latter -- with an option to
use bcopy instead.)
add support for the preprocessor macro LIBSA_NO_DISKLABEL_MSGS, which
causes disklabel() to return '1' as msg rather than a string. Can
be used if the boot blocks don't care about the string, and need to
save the space.
add support for the preprocessor macro LIBSA_SINGLE_FILESYSTEM, which
if defined causes all of the file system switch code to be removed.
Its value should be the name of the file system supported by the
boot block, e.g. "ufs" for the FFS file system. calls to the
file system functions open, close, etc., which were previously
done through a function switch are then done via direct invocation
of <fs>_open, <fs>_close, etc. (e.g. ufs_open, ...).
add support for the preprocessor macro LIBSA_SINGLE_DEVICE, which
does the equivalent of LIBSA_SINGLE_FILESYSTEM but for the device
switch table. Device entry pointes are expected to be named
<dev>foo, e.g. the 'strategy' routine used when LIBSA_SINGLE_DEVICE
is set to 'disk' is diskstrategy.
make ufs.c f_nindir array be unsigned ints. the fact that it was signed
caused ufs.c to require signed division routines (which were otherwise
unnecessary for a small boot block).

Some files containing more than one function are split. This reduces the
size of the resulting loader. The read_inode() function now returns the
result of the strategy function instead of success in all cases (ufs.c).
Fixes pr#1817

Fixes pr#1817

To support big partitions we need to make sure all byte offsets are calculated
in 64 bit arithmetic. Pointed out by Rob Newberry.
Unfortunately this causes a code size increase breaking some boot blocks,
so conditionalize it and use 32 bit arithmetic if SA_DOSFS_NO_BIG_PART_SUPPORT
is defined.

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c
