Subject: [PATCH v2 0/4] ext4: fix use-after-free in ext4_xattr_set_entry
Date: Wed, 15 Jun 2022 12:06:26 +0800	[thread overview]
Message-ID: <20220615040630.808783-1-libaokun1@huawei.com> (raw)

This series adds a macro for whether there is space for xattr in
ext4 inode, and fixes some problems with this macro.

V1->V2:
	Split the patch to make the logic clearer.
	Rename macro to EXT4_INODE_HAVE_XATTR_SPACE.

Baokun Li (4):
  ext4: add EXT4_INODE_HAVE_XATTR_SPACE macro in xattr.h
  ext4: fix use-after-free in ext4_xattr_set_entry
  ext4: correct max_inline_xattr_value_size computing
  ext4: correct the misjudgment in ext4_iget_extra_inode
