disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new fsck_ffs operations "-c ea" and "-c no-ea" to convert file systems
from UFS2 to UFS2ea and vice-versa (both of which delete all existing extended
attributes in the process).
used instead of secsize obtained by SAIOSECSIZE ioctl.
This hack avoids divdi3 and friends from being linked, in order to
support variable secsize for some archs.
Should be useful for ancient archs, for which secsize is fixed.
Thanks christos@ for comment.
This is wrong reasoning; 68020 and above (incl. 040 and 060) support
32-bit displacements for PC relative addressing (via "fully extension
addressing mode" with null index register).
I've still not figured out what goes wrong with amiga/boot(8) when
compiled without -l option for gas(1)...

This hack avoids divdi3 and friends from being linked, in order to
support variable secsize.
This is useful for amiga/boot(8); it is loaded by firmware into
unpredictable address, and therefore all symbols should be
addressable by PC relative mode with only 16-bit displacements.
See sys/arch/amiga/stand/bootblock/{boot/bbstart.s,elf2bb,txlt} for
more details.
This harmonizes efiboot and the various x86 bootloaders to use shared
code for printing the banner. By friendly coincidence, it also adds
support for specifying 'banner=' in arm efiboot's boot.cfg, as on x86.
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.
- 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*.
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.
* XXX Hack alert. GCC 8.3 mis-compiles this function and calls
* strncmp() with the wrong second pointer, as seen in PR#54703.
*
* Until the real cause is located, work around it by using -O1
* for this function.
this hack is restricted to i386.
opposite byte order (for arm EFI bootloader).
XXX
Currently, it is restricted to load_elf*.c. It would be nice if we can
recognize disklabel and filesystem of opposite byte order.
to update the boot-loader to push all modules required to support the
booted filesystem. We treat the fsmod string as a slash-separated list
of module names (relative to kern.module.path), rather than as a single
module path name.
Note that ffsv1 and ffsv2 are still exempted from the boot-loader's
auto-push, but the list of required filesystems is still noted in the
source.
Also note that arch/sandpoint needs a similar change. I have not made
this change because I am totally unable to test it.
Tested on my kernel with _no_ built-in file-systems and with the ffs
bootloader settings of fsmod enabled.
that passing variables to recursive makes with :q works as expected.
- Revert :Q to work as before.
- Adjust makefiles that use recursive make to use :q
