fs/vfs/security: pass last path component to LSM on inode creation

2011-02-01T16:12:29+00:00

SELinux would like to implement a new labeling behavior of newly created
inodes.  We currently label new inodes based on the parent and the creating
process.  This new behavior would also take into account the name of the
new object when deciding the new label.  This is not the (supposed) full path,
just the last component of the path.

This is very useful because creating /etc/shadow is different than creating
/etc/passwd but the kernel hooks are unable to differentiate these
operations.  We currently require that userspace realize it is doing some
difficult operation like that and than userspace jumps through SELinux hoops
to get things set up correctly.  This patch does not implement new
behavior, that is obviously contained in a seperate SELinux patch, but it
does pass the needed name down to the correct LSM hook.  If no such name
exists it is fine to pass NULL.

jffs2: Dynamically choose inocache hash size

2010-10-24T23:57:19+00:00

When JFFS2 is used for large volumes, the mount times are quite long.
Increasing the hash size provides a significant speed boost on the OLPC
XO-1 laptop.

Add logic that dynamically selects a hash size based on the size of
the medium. A 64mb medium will result in a hash size of 128, and a 512mb
medium will result in a hash size of 1024.

jffs2: Add 'work_done' return value from jffs2_erase_pending_blocks()

2010-05-19T15:32:52+00:00

We're about to start calling this from the jffs2_garbage_collect_pass(), and
we'll want to know whether it actually did anything or not.

[JFFS2] remove junk prototypes

2009-01-09T21:05:21+00:00

'rb_prev()', 'rb_next()' and 'rb_replace_node()' are declared in
include/linux/rbtree.h, no need for JFFS2 to re-declare them. I
believe these are left-overs from the old days when the common
RB tree code did not have those call and JFFS2 had private
implementation.

[JFFS2] Track parent inode for directories (for NFS export)

2008-05-01T17:47:17+00:00

To support NFS export, we need to know the parent inode of directories.
Rather than growing the jffs2_inode_cache structure, share space with
the nlink field -- which was always set to 1 for directories anyway.

[JFFS2] Finally remove redundant ref->__totlen field.

2008-04-23T00:26:12+00:00

Haven't had any complaints about it recently, despite having the test
code enabled to verify that the calculated length is correct.

Kill it off, just by #undef TEST_TOTLEN for now; removing it for real
can come a little later.

[JFFS2] Deletion dirents should be REF_NORMAL, not REF_PRISTINE.

Otherwise they'll never actually get garbage-collected.
