1d41def9a3 restore(8) does not check for write failure while building two temp
files containing directory and ownership data. If /tmp fills, the
console is blasted with zillions of "file system full" errors, and
restore continues on, even though directory and/or ownership data
has been lost. This is particularly likely to happen when running
from the live CD, which has little /tmp space.

01ee9020b3 Update the dump program to save extended attributes. Update
the restore program to restore all dumped extended attributes.

If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.

The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.

This resolves PR 93085 which will be closed once the code
has been MFC'ed.

Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

12df44b425 Add a "-D" flag to restore which puts it into "degraded" mode. This
makes restore less efficient, but it makes a bigger effore to read
corrupted dumps. Specifiacally, when in degreded mode:

	1) Restore shifts the input by 1 byte if it sees a problem,
	rather than one tape block.
	2) It doesn't assume the inodes are stored in ascending order.
	3) It turns some panics into warning printfs.

We also verify some fields more carefully than before.

There's probably more a degreded mode could do, but this seems to
help a lot.

931f79b738 Restore the ability to read FreeBSD 1 tapes (and I think any net2
based tapes, but I'm not sure where NFS_MAGIC was introduced after
4.3).  When support for the pre-4.4 format was removed (the ability to
read 4.2 and 4.3 BSD tapes), the old format inode conversion was
junked as well.  However, FreeBSD 1 dump tapes use the NFS_MAGIC
format, but have this inode format.  Before, restore would fail
complaining that '.' wasn't found and the root directory wasn't on
this tape.  Since the conversion from the not so old format is
relatively trivial, restore the code to make that conversion.

FreeBSD 1 dumps are once again readable.

like they aren't used for TS_INODE, but conversion costs so little
there that I've not removed them there (in case my grep was wrong).

a82970a04e The .Nm utility. 2002-07-06 19:35:14 +00:00
mckusick
88d85c15ef 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).
