      [PATCH] isofs: show hidden files, add granularity for assoc/hidden files flags · 9769f4eb
      由 Jeremy White 提交于 
      The current isofs treatment of hidden files is flawed in two ways.  First,
it does not provide sufficient granularity; it hides both 'hidden' files
and 'associated' files (resource fork for Mac files).  Second, the default
behavior to completely strip hidden files, while an admirable
implementation of the spec, is a poor choice given the real world use of
hidden files as a poor mans copy protection scheme for MSDOS and Windows
based systems.  A longer description of this is available here:

   http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html

This patch was originally built after a few private conversations with Alan
Cox; I shamefully failed to persist in seeing it go forward, I hope to make
amends now.

This patch introduces granularity by allowing explicit control for both
hidden and associated files.  It also reverses the default so that by
default, hidden files are treated as regular files on the iso9660 file
system.

This allow Wine to process Windows CDs, including those that are hybrid
Mac/Windows CDs properly and completely, without our having to go muck up
peoples fstabs as we do now.  (I have tested this with such a hybrid +
hidden CD and have verified that this patch works as claimed).

      [PATCH] rock: handle directory overflows · f2966632
      由 Andrew Morton 提交于 
      Handle the case where the variable-sized part of a rock-ridge directory entry
overhangs the end of the buffer which we allocated for it.

      [PATCH] rock: rename union members · 642217c1
      由 Andrew Morton 提交于 
      The silly thing does:

	struct foo { ... };
	...
	#define foo 42

so you can no longer refer to `struct foo' in C code.

Rename the structures.

      [PATCH] rock.c: handle corrupted directories · e595447e
      由 Andrew Morton 提交于 
      The bug in rock.c is that it's totally trusting of the contents of the
directories.  If the directory says there's a continuation 10000 bytes into
this 4k block then we cheerily poke around in memory we don't own and oops.

So change rock_continue() to apply various sanity checks, at least ensuring
that the offset+length remain within the bounds for the header part of a
struct rock_ridge directory entry.

Note that the kernel can still overindex the buffer due to the variable size
of the rock-ridge directory entries.  We cannot check that in rock_continue()
unless we go parse the directory entry's signature and work out its size.
