fs/ntfs3: Fix invalid free in log_replay

2022-06-09T08:30:56+00:00

commit f26967b9f7a830e228bb13fb41bd516ddd9d789d upstream. log_read_rst() returns ENOMEM error when there is not enough memory. In this case, if info is returned without initialization, it attempts to kfree the uninitialized info->r_page pointer. This patch moves the memset initialization code to before log_read_rst() is called.

fs/ntfs3: Restore ntfs_xattr_get_acl and ntfs_xattr_set_acl functions

2022-06-09T08:29:29+00:00

commit 87e21c99bad763524c953ff4d1a61ee19038ddc2 upstream. Apparently we need to maintain these functions with ntfs_get_acl_ex and ntfs_set_acl_ex.

fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()'

2022-06-09T08:29:29+00:00

commit e589f9b7078e1c0191613cd736f598e81d2390de upstream. All error handling paths lead to 'out' where many resources are freed. Do it as well here instead of a direct return, otherwise 'log', 'ra' and 'log->one_page_buf' (at least) will leak.

fs/ntfs3: In function ntfs_set_acl_ex do not change inode->i_mode if called from function ntfs_init_acl

commit 9186d472ee780fabf74424756c4c00545166157e upstream. ntfs_init_acl sets mode. ntfs_init_acl calls ntfs_set_acl_ex. ntfs_set_acl_ex must not change this mode.

fs/ntfs3: Check new size for limits

commit 114346978cf61de02832cc3cc68432a3de70fb38 upstream. We must check size before trying to allocate. Size can be set for example by "ulimit -f".

fs/ntfs3: Keep preallocated only if option prealloc enabled

commit e95113ed4d428219e3395044e29f5713fc446720 upstream. If size of file was reduced, we still kept allocated blocks. This commit makes ntfs3 work as other fs like btrfs.

fs/ntfs3: Fix fiemap + fix shrink file size (to remove preallocated space)

2022-06-09T08:29:28+00:00

commit 3880f2b816a7e4ca889b7e8a42e6c62c5706ed36 upstream. Two problems: 1. ntfs3_setattr can't truncate preallocated space; 2. if allocated fragment "cross" valid size, then fragment splits into two parts: - normal part; - unwritten part (here we must return FIEMAP_EXTENT_LAST). Before this commit we returned FIEMAP_EXTENT_LAST for whole fragment.

fs/ntfs3: provide block_invalidate_folio to fix memory leak

commit 724bbe49c5e427cb077357d72d240a649f2e4054 upstream. The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes memory leak. If you write to the filesystem and then unmount it, the cached written data are not freed and they are permanently leaked.
