When insert_inode_locked() fails in ext3_new_inode() it most likely
means inode bitmap got corrupted and we allocated again inode which
is already in use. Also doing unlock_new_inode() during error recovery
is wrong since inode does not have I_NEW set. Fix the problem by jumping
to fail: (instead of fail_drop:) which declares filesystem error and
does not call unlock_new_inode().Reviewed-by: Eric Sandeen

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.Signed-off-by: Eric Paris

If a filesystem has inode size > 128 and someone deletes lost+found and
reuses inode 11 for some other file, extented attributes set for this
inode before umount will get lost after remounting the filesystem. This
is because extended attributes will get stored in an inode but ext3_iget
will ignore them due to workaround of a bug in an old mkfs.Fix the problem by initializing i_extra_isize to 0 for freshly allocated
inodes where mkfs workaround in ext3_iget applies. This way these inodes
will always store extended attributes in a special block and no problems
occur.The bug was spotted and a reproduction test provided by:

In commit 9df93939b735 ("ext3: Use bitops to read/modify
EXT3_I(inode)->i_state") ext3 changed its internal 'i_state' variable to
use bitops for its state handling. However, unline the same ext4
change, it didn't actually change the name of the field when it changed
the semantics of it.As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that
initialized the field to EXT3_STATE_NEW. And that does not work
_at_all_ when we're now working with individually named bits rather than
values that get masked. So the code tried to mark the state to be new,
but in actual fact set the field to EXT3_STATE_JDATA. Which makes no
sense at all, and screws up all the code that checks whether the inode
was newly allocated.In particular, it made the xattr code unhappy, and caused various random
behavior, like apparentlyhttps://bugzilla.redhat.com/show_bug.cgi?id=577911
So fix the initialization, and rename the field to match ext4 so that we
don't have this happen again.Cc: James Morris

At the moment there are few restrictions on which flags may be set on
which inodes. Specifically DIRSYNC may only be set on directories and
IMMUTABLE and APPEND may not be set on links. Tighten that to disallow
TOPDIR being set on non-directories and only NODUMP and NOATIME to be set
on non-regular file, non-directories.Introduces a flags masking function which masks flags based on mode and
use it during inode creation and when flags are set via the ioctl to
facilitate future consistency.Signed-off-by: Duane Griffin

Stop the EXT3 filesystem from using iget() and read_inode(). Replace
ext3_read_inode() with ext3_iget(), and call that instead of iget().
ext3_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.ext3_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.[akpm@linux-foundation.org: coding-style fixes]

This eliminates the i_blksize field from struct inode. Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.[bunk@stusta.de: cleanup]

Some of the in-kernel ext3 block variable type are treated as signed 4 bytes
int type, thus limited ext3 filesystem to 8TB (4kblock size based). While
trying to fix them, it seems quite confusing in the ext3 code where some
blocks are filesystem-wide blocks, some are group relative offsets that need
to be signed value (as -1 has special meaning). So it seem saner to define
two types of physical blocks: one is filesystem wide blocks, another is
group-relative blocks. The following patches clarify these two types of
blocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3
filesystem limit to 8TB.With this series of patches and the percpu counter data type changes in the mm
tree, we are able to extend exts filesystem limit to 16TB.This work is also a pre-request for the recent >32 bit ext3 work, and makes
the kernel to able to address 48 bit ext3 block a lot easier: Simply redefine
ext3_fsblk_t from unsigned long to sector_t and redefine the format string for
ext3 filesystem block corresponding.Two RFC with a series patches have been posted to ext2-devel list and have
been reviewed and discussed:
http://marc.theaimsgroup.com/?l=ext2-devel&m=114722190816690&w=2http://marc.theaimsgroup.com/?l=ext2-devel&m=114784919525942&w=2
Patches are tested on both 32 bit machine and 64 bit machine, 8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39). Tests
includes overnight fsx, tiobench, dbench and fsstress.This patch:
Defines ext3_fsblk_t and ext3_grpblk_t, and the printk format string for
filesystem wide blocks.This patch classifies all block group relative blocks, and ext3_fsblk_t blocks
occurs in the same function where used to be confusing before. Also include
kernel bug fixes for filesystem wide in-kernel block variables. There are
some fileystem wide blocks are treated as int/unsigned int type in the kernel
currently, especially in ext3 block allocation and reservation code. This
patch fixed those bugs by converting those variables to ext3_fsblk_t(unsigned
long) type.Signed-off-by: Mingming Cao

I noticed some problems while running ext3 with the debug flag set on.
More precisely, I was unable to umount the filesystem. Some investigation
took me to the patch that follows.At a first glance , the lock/unlock I've taken out seems really not
necessary, as the main code (outside debug) does not lock the super. The
only additional danger operations that debug code introduces seems to be
related to bitmap, but bitmap operations tends to be all atomic anyway.I also took the opportunity to fix 2 spelling errors.
