hfsplus: fix overflow in sector calculations in hfsplus_submit_bio

2012-06-22T18:34:14+00:00

commit a6dc8c04218eb752ff79cdc24a995cf51866caed upstream.

The variable io_size was unsigned int, which caused the wrong sector number
to be calculated after aligning it. This then caused mount to fail with big
volumes, as backup volume header information was searched from a
wrong sector.

hfsplus: Fix potential buffer overflows

2012-05-07T15:56:50+00:00

commit 6f24f892871acc47b40dd594c63606a17c714f77 upstream.

Commit ec81aecb2966 ("hfs: fix a potential buffer overflow") fixed a few
potential buffer overflows in the hfs filesystem.  But as Timo Warns
pointed out, these changes also need to be made on the hfsplus
filesystem as well.

hfsplus: Fix kfree of wrong pointers in hfsplus_fill_super() error path

2011-10-25T05:10:17+00:00

commit f588c960fcaa6fa8bf82930bb819c9aca4eb9347 upstream.

Commit 6596528e391a ("hfsplus: ensure bio requests are not smaller than
the hardware sectors") changed the pointers used for volume header
allocations but failed to free the correct pointers in the error path
path of hfsplus_fill_super() and hfsplus_read_wrapper.

The second hunk came from a separate patch by Pavel Ivanov.

hfsplus: ensure bio requests are not smaller than the hardware sectors

2011-10-25T05:10:15+00:00

commit 6596528e391ad978a6a120142cba97a1d7324cb6 upstream.

Currently all bio requests are 512 bytes, which may fail for media
whose physical sector size is larger than this. Ensure these
requests are not smaller than the block device logical block size.

hfsplus: Fix double iput of the same inode in hfsplus_fill_super()

2011-06-30T11:38:39+00:00

There is a misprint in resource deallocation code on error path in
hfsplus_fill_super(): the sbi->alloc_file inode is iput twice,
while the root inode in not iput at all.

hfsplus: add missing call to bio_put()

2011-06-30T11:28:32+00:00

hfsplus leaks bio objects by failing to call bio_put() on the bios
it allocates. Add the missing call to fix the leak.

vfs: push dentry_unhash on rename_dir into file systems

2011-05-26T11:26:48+00:00

Only a few file systems need this.  Start by pushing it down into each
rename method (except gfs2 and xfs) so that it can be dealt with on a
per-fs basis.

vfs: push dentry_unhash on rmdir into file systems

2011-05-26T11:26:47+00:00

Only a few file systems need this.  Start by pushing it down into each
fs rmdir method (except gfs2 and xfs) so it can be dealt with on a per-fs
basis.

This does not change behavior for any in-tree file systems.
