Based on feedback and contributions generously provided by Chris
Wright, I have produced a new BSD Secure Levels LSM patch against the
lsm-2.6 BK tree.
Changelog:
02/19/2004 Updated by Michael A. Halcrow:
1. Fixed bug in plaintextToSha1 where the hash would not be
calculated properly in the event that the plaintext
spanned multiple pages.
2. Gave seclvl sysfs attributes an owner, to fix a bug whereby
opening a file in sysfs/seclvl, removing the module,
and then reading or writing that file handle led to a
kernel oops.
02/13/2004 Updated by Chris Wright:
1. Made things static where possible.
2. Removed racey is_mounted. Replaced with bd_claiming the
device, holding it while open, and bd_releasing on
close. This will still not work with things like
loopback file mounts, but it should get partitions,
etc. right.
3. Updated to new module parameters interface. Removed some
of the StudlyCaps.
4. Made sure that jiffies is unsigned long in rate limiting.
5. Removed unnecessary zero'ing out of static memory.
Mike
