Summary
udf: Fix bogus checksum computation in udf_rename()
Details

In the Linux kernel, the following vulnerability has been resolved:

udf: Fix bogus checksum computation in udf_rename()

Syzbot reports uninitialized memory access in udfrename() when updating checksum of '..' directory entry of a moved directory. This is indeed true as we pass on-stack diriter.fi to the udfupdatetag() and because that has only struct fileIdentDesc included in it and not the impUse or name fields, the checksumming function is going to checksum random stack contents beyond the end of the structure. This is actually harmless because the following udffiiterwritefi() will recompute the checksum from on-disk buffers where everything is properly included. So all that is needed is just removing the bogus calculation.
