check hash to cylinder groups. If a check hash fails when a cylinder
group is read, no further allocations are attempted in that cylinder
group until it has been fixed by fsck. This avoids a class of
filesystem panics related to corrupted cylinder group maps. The
hash is done using crc32c.
Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily
used in embedded systems with small memories and low-powered processors
which need as light-weight a filesystem as possible.
Specifics of the changes:
sys/sys/buf.h:
Add BX_FSPRIV to reserve a set of eight b_xflags that may be used
by individual filesystems for their own purpose. Their specific
definitions are found in the header files for each filesystem
that uses them. Also add fields to struct buf as noted below.
sys/kern/vfs_bio.c:
It is only necessary to compute a check hash for a cylinder
group when it is actually read from disk. When calling bread,
you do not know whether the buffer was found in the cache or
read. So a new flag (GB_CKHASH) and a pointer to a function to
perform the hash has been added to breadn_flags to say that the
function should be called to calculate a hash if the data has
been read. The check hash is placed in b_ckhash and the B_CKHASH
flag is set to indicate that a read was done and a check hash
calculated. Though a rather elaborate mechanism, it should
also work for check hashing other metadata in the future. A
kernel internal API change was to change breada into a static
fucntion and add flags and a function pointer to a check-hash
function.
sys/ufs/ffs/fs.h:
Add flags for types of check hashes; stored in a new word in the
superblock. Define corresponding BX_ flags for the different types
of check hashes. Add a check hash word in the cylinder group.
sys/ufs/ffs/ffs_alloc.c:
In ffs_getcg do the dance with breadn_flags to get a check hash and
if one is provided, check it.
sys/ufs/ffs/ffs_vfsops.c:
Copy across the BX_FFSTYPES flags in background writes.
Update the check hash when writing out buffers that need them.
sys/ufs/ffs/ffs_snapshot.c:
Recompute check hash when updating snapshot cylinder groups.
sys/libkern/crc32.c:
lib/libufs/Makefile:
lib/libufs/libufs.h:
lib/libufs/cgroup.c:
Include libkern/crc32.c in libufs and use it to compute check
hashes when updating cylinder groups.
Four utilities are affected:
sbin/newfs/mkfs.c:
Add the check hashes when building the cylinder groups.
sbin/fsck_ffs/fsck.h:
sbin/fsck_ffs/fsutil.c:
Verify and update check hashes when checking and writing cylinder groups.
sbin/fsck_ffs/pass5.c:
Offer to add check hashes to existing filesystems.
Precompute check hashes when rebuilding cylinder group
(although this will be done when it is written in fsutil.c
it is necessary to do it early before comparing with the old
cylinder group)
sbin/dumpfs/dumpfs.c
Print out the new check hash flag(s)
sbin/fsdb/Makefile:
Needs to add libufs now used by pass5.c imported from fsck_ffs.

/*
|
|
* First, the polynomial itself and its table of feedback terms. The
|
|
* polynomial is
|
|
* X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
|
|
*
|
|
* Note that we take it "backwards" and put the highest-order term in
|
|
* the lowest-order bit. The X^32 term is "implied"; the LSB is the
|
|
* X^31 term, etc. The X^0 term (usually shown as "+1") results in
|
|
* the MSB being 1
|
|
*
|
|
* Note that the usual hardware shift register implementation, which
|
|
* is what we're using (we're merely optimizing it by doing eight-bit
|
|
* chunks at a time) shifts bits into the lowest-order term. In our
|
|
* implementation, that means shifting towards the right. Why do we
|
|
* do it this way? Because the calculated CRC must be transmitted in
|
|
* order from highest-order term to lowest-order term. UARTs transmit
|
|
* characters in order from LSB to MSB. By storing the CRC this way
|
|
* we hand it to the UART in the order low-byte to high-byte; the UART
|
|
* sends each low-bit to hight-bit; and the result is transmission bit
|
|
* by bit from highest- to lowest-order term without requiring any bit
|
|
* shuffling on our part. Reception works similarly
|
|
*
|
|
* The feedback terms table consists of 256, 32-bit entries. Notes
|
|
*
|
|
* The table can be generated at runtime if desired; code to do so
|
|
* is shown later. It might not be obvious, but the feedback
|
|
* terms simply represent the results of eight shift/xor opera
|
|
* tions for all combinations of data and CRC register values
|
|
*
|
|
* The values must be right-shifted by eight bits by the "updcrc
|
|
* logic; the shift must be unsigned (bring in zeroes). On some
|
|
* hardware you could probably optimize the shift in assembler by
|
|
* using byte-swap instructions
|
|
* polynomial $edb88320
|
|
