629e80effb The .Nm utility. 2002-07-06 19:35:14 +00:00
Kirk McKusick
1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

It does not help modern compilers, and some may take some hit from it.

ab3d6ee098 Use a more robust scheme for determining how many blocks to skip
after an EOT-terminated volume. We keep track of the current record
number, and synchronise it with the c_tapea field each time we read
a header. Avoid the use of c_firstrec because some bugs in dump can
cause it to be set incorrectly.

Move the initialisation of some variables to avoid compiler warnings.

dea08b6818 When we reach the end of the dump in findinode(), ask for another
volume if we missed some earlier tapes (the user can still enter
'none' later if the tapes are unavailable). Previously with 'x'
restores, we might not ask for all tapes if the tapes are supplied
in reverse order.

Clarify the message that describes what volume should be mounted
first; reverse order is only efficient when extracting a few files.

cfd8a00918 In createfiles(), properly handle a number of cases where no further
volumes are available, instead of getting stuck in a loop calling
getvol(). Normally restore in 'x' or 'i' modes will ask for a new
(earlier) volume when the current inode number on the tape is greater
than the last inode to be restored, since there can be no further
inodes of interest on that volume. However we don't want to change
volumes in this case either if the user explicitly said that there
are no more tapes, or if we are looking at the first volume.

When no more volumes are available but there are still inodes that
we have not found, we now just fall through to the code that prints
out a list of any missing files, so the restore completes normally.
Also simplify the logic a bit by always returning to the start of
the main for(;;) loop whenever the volume has changed.

This should completely fix the "Changing volumes on pipe input" bug
that is often observed when restoring dumps of active filesystems.

1603684d77 Fix a number of long-standing restore bugs in tape.c, mainly relating
to multi-volume restores:
 - In findinode(), keep a copy of header->c_type so that we don't
   exit the do-while loop until we have processed the current header.
   Exiting too early leaves curfile.ino set to 0, which confuses
   the logic in createfiles(), so multi-volume restores with the
   'x' command don't work if you follow the instructions and supply
   the tapes in reverse order.  This appears to have been broken
   by CSRG revision 5.33 tape.c (Oct 1992).
 - The logic in getvol() for deciding how many records to skip after
   the volume header was confused; sometimes it would skip too few
   records and sometimes too many, leading to "resync restore"
   warnings and missing files. Skip to the next header only when
   the current action is not `USING'. Work around a dump bug that
   sets c_count incorrectly in the volume header of the first tape.
   Some of the problems here date back to at least 1991.
 - Back out revision 1.23. This appeared to avoid warnings about
   missing files in the 'rN' verification case, but it made the
   problems with the 'x' command worse by stopping getvol() from
   even attempting to find the first inode number on the newly
   inserted tape. The bug it addressed is fixed by correcting the
   skipping logic as described above.
 - Save the value of `tpblksread' in case the wrong volume is
   supplied, because it is incremented each time we read a volume
   header. We already saved `blksread' for the same reson.

170ac683f2 I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions.  e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard.  They will eventually be replaced when a real standard
comes out of committee.

5b3817c60b Make the protocol/dumprestore.h header match restore's idea of the dump
header for the case where sizeof(time_t) != sizeof(int).  dumprestore.h
was embedding time_t when it should have been embedding int32_t.

protocoll/file-format time and time_t.

860ca8fd85 restore(8) doesn't need to be setgid `tty', and never did.
At the times, restore(8) and rrestore(8) were the different
utilities.  rrestore(8) was installed setuid `root', while
restore(8) with usual ownership and privileges.  Later on,
on August 28, 1991 (what a coincidence!), rrestore(8) code
was merged with restore(8).  The setgid `tty' bit then was
accidentally put.
