Problem Description:

Comment 1 Stefan Richter 2007-01-08 11:18:08 UTC

Bug status: I plan to kick all userspace library code as well as needless IEEE
1394 -> IEEE 1212 abstractions out of drivers/ieee1394/csr1212.[ch]. (The code
was designed to work with other buses besides 1394 and to be compilable as a
userspace library. Today there is no benefit from this design, only bloat.) In
doing so I will have an eye on potentially missing input validation.

Comment 2 Stefan Richter 2007-05-18 06:52:49 UTC

Various simplifications of the csr1212 code went into 2.6.22-rc1.  While working
on them, I didn't notice any obvious bug.  I am closing this bug as
unreproducible for now; reopen if necessary.
