and exit.
Previously, combinations would produce unintended results, such as
deleting the primary IP on an interface, instead of deleting an specified
alias.
safe (since there's two separate mallocs using sbrk(2) in that case)
XXX: local malloc provided for mfs memory store allocation; need to
investigate if system (phk) malloc can be used instead.
disklabel is created as per mfs on "swap".
* add -Z option: pre-zero the -F image file before use. this is necessary if
the image is to be used with vnd(4) because by default the files created
with -F have "holes" and vnd doesn't cope with that.
* support 'k', 'm', 'g' suffixes for all options which take numeric arguments.
provide strsuftoi() which performs the parsing mechanism.
* improve man page description of various options
* replace "filesystem" with "file system"
* when displaying usage for mfs, only list mfs options
* minor KNF and WARNS=2 cleanups
- in replacement malloc(), if sbrk(2) returns (void *)-1, convert to NULL
before returning
- in replacement calloc(), check return value of malloc() before zeroing result
Kernels and tools understand both v1 and v2 filesystems; newfs_lfs
generates v2 by default. Changes for the v2 layout include:
- Segments of non-PO2 size and arbitrary block offset, so these can be
matched to convenient physical characteristics of the partition (e.g.,
stripe or track size and offset).
- Address by fragment instead of by disk sector, paving the way for
non-512-byte-sector devices. In theory fragments can be as large
as you like, though in reality they must be smaller than MAXBSIZE in size.
- Use serial number and filesystem identifier to ensure that roll-forward
doesn't get old data and think it's new. Roll-forward is enabled for
v2 filesystems, though not for v1 filesystems by default.
- The inode free list is now a tailq, paving the way for undelete (undelete
is not yet implemented, but can be without further non-backwards-compatible
changes to disk structures).
- Inode atime information is kept in the Ifile, instead of on the inode;
that is, the inode is never written *just* because atime was changed.
Because of this the inodes remain near the file data on the disk, rather
than wandering all over as the disk is read repeatedly. This speeds up
repeated reads by a small but noticeable amount.
Other changes of note include:
- The ifile written by newfs_lfs can now be of arbitrary length, it is no
longer restricted to a single indirect block.
- Fixed an old bug where ctime was changed every time a vnode was created.
I need to look more closely to make sure that the times are only updated
during write(2) and friends, not after-the-fact during a segment write,
and certainly not by the cleaner.
same configuration format that -c and -C use.
this is useful if you're using autoconfig and you've misplaced the
/etc/raidXXX.conf files
* "filesystem" -> "file system", and other man page cleanups.
Some hosts and gateways ignore record route, but not "many." Of course,
more are firewalled. But that's not what was meant here.
Expand flood-pinging admonition to include multicast addresses.
Note flags that conflict with ping under Solaris and FreeBSD.
Reorder BUGS in rough order of significance.
Currently, only Aironet ("an") driver/card can be used.
nwkey persist (IEEE 802.11 devices only) Enable WEP encryption for IEEE
802.11-based wireless network interfaces with the persis-
tent key written in the network card.
nwkey persist:key
(IEEE 802.11 devices only) Write the key to the persis-
tent memory of the network card, and enable WEP encryp-
tion for IEEE 802.11-based wireless network interfaces
with the key.
(force) is given. fsck(8) will return with a zero exit status if "fsck -p"
is used in this circumstance, but all other invocations (e.g, "fsck",
"fsck /filesystem", "fsck -p /filesystem") will return with a non-zero exit
status in this circumstance.
Per discussions with various people including Bill Sommerfeld.
- Use "file system" instead of "filesystem"
