hfsplus: switch to rcu-delayed unloading of nls and freeing ->s_fs_info

2024-02-25T07:10:31+00:00

->d_hash() and ->d_compare() use those, so we need to delay freeing
them.

fs: hfsplus: fix UAF issue in hfsplus_put_super

2023-03-03T05:54:23+00:00

The current hfsplus_put_super first calls hfs_btree_close on
sbi->ext_tree, then invokes iput on sbi->hidden_dir, resulting in an
use-after-free issue in hfsplus_release_folio.

As shown in hfsplus_fill_super, the error handling code also calls iput
before hfs_btree_close.

To fix this error, we move all iput calls before hfsplus_btree_close.

Note that this patch is tested on Syzbot.

fs/hfsplus: Use the enum req_op and blk_opf_t types

2022-07-14T18:14:32+00:00

Improve static type checking by using the enum req_op type for variables
that represent a request operation and the new blk_opf_t type for
variables that represent request flags. Combine the last two
hfsplus_submit_bio() arguments into a single argument.

fs: allocate inode by using alloc_inode_sb()

2022-03-22T22:57:03+00:00

The inode allocation is supposed to use alloc_inode_sb(), so convert
kmem_cache_alloc() of all filesystems to alloc_inode_sb().

block: remove the error_sector argument to blkdev_issue_flush

The argument isn't used by any caller, and drivers don't fill out
bi_sector for flush requests either.
