hfsplus: fix bless ioctl when used with hardlinks

2012-06-22T18:36:57Z

commit 7dea9665fee828fb56db3bae5b9685d9fa006d33 upstream. HFS+ doesn't really implement hard links - instead, hardlinks are indicated by a magic file type which refers to an indirect node in a hidden directory. The spec indicates that stat() should return the inode number of the indirect node, but it turns out that this doesn't satisfy the firmware when it's looking for a bootloader - it wants the catalog ID of the hardlink file instead. Fix up this case. Signed-off-by: Matthew Garrett Signed-off-by: Christoph Hellwig Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

hfsplus: fix overflow in sector calculations in hfsplus_submit_bio

2012-06-22T18:36:57Z

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

2012-05-05T00:11:24Z

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: add an ioctl to bless files

2012-03-21T01:29:53Z

Making an hfsplus partition bootable requires the ability to "bless" a file by putting its inode number in the volume header. Doing this from userspace on a mounted filesystem is impractical since the kernel will write back the original values on unmount. Add an ioctl to allow userspace to update the volume header information based on the target file. Signed-off-by: Matthew Garrett Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

hfsplus: change finder_info to u32

2012-03-21T01:29:52Z

The finder_info block in the hfsplus volume header is currently defined as an array of 8 bit values, but TN1150 defines it as being an array of 32 bit values. Fix for convenience. Signed-off-by: Matthew Garrett Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

hfsplus: initialise userflags

2012-03-21T01:29:52Z

The userflags field was being written to the filesystem without being initialised. Make sure it's clear, since otherwise files end up with garbage attributes. Signed-off-by: Matthew Garrett Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro
