nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors

nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors
[ Upstream commit 7373a51e7998b508af7136530f3a997b286ce81c ]
The error handling in nilfs_empty_dir() when a directory folio/page read fails is incorrect, as in the old ext2 implementation, and if the folio/page cannot be read or nilfs_check_folio() fails, it will falsely determine the directory as empty and corrupt the file system.
In addition, since nilfs_empty_dir() does not immediately return on a failed folio/page read, but continues to loop, this can cause a long loop with I/O if i_size of the directory's inode is also corrupted, causing the log writer thread to wait and hang, as reported by syzbot.
Fix these issues by making nilfs_empty_dir() immediately return a false value (0) if it fails to get a directory folio/page.

nilfs2: fix OOB in nilfs_set_de_type
commit c4a7dc9523b59b3e73fd522c73e95e072f876b16 upstream.
The size of the nilfs_type_by_mode array in the fs/nilfs2/dir.c file is defined as "S_IFMT >> S_SHIFT"
nilfs2: fix OOB in nilfs_set_de_type
commit c4a7dc9523b59b3e73fd522c73e95e072f876b16 upstream.
The size of the nilfs_type_by_mode array in the fs/nilfs2/dir.c file is defined as "S_IFMT >> S_SHIFT", but the nilfs_set_de_type() function, which uses this array, specifies the index to read from the array in the same way as "(mode & S_IFMT) >> S_SHIFT".
static void nilfs_set_de_type(struct nilfs_dir_entry *de, struct inode *inode) { umode_t mode = inode->i_mode;
de->file_type = nilfs_type_by_mode[(mode & S_IFMT)>>S_SHIFT]; // oob }
However, when the index is determined this way, an out-of-bounds (OOB) error occurs by referring to an index that is 1 larger than the array size when the condition "mode & S_IFMT == S_IFMT" is satisfied. Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.

nilfs2: convert to ctime accessor functions
In later patches, we're going to change how the inode's ctime field is used. Switch to using accessor functions instead of raw accesses of inode->i_ctime.

fs: Replace CURRENT_TIME with current_time() for inode timestamps
CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_time() instead.
CURRENT_TIME is also not y2038 safe.
This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. As part of the effort current_time() will be extended to do range checks. Hence, it is necessary for all file system timestamps to use current_time(). Also, current_time() will be transitioned along with vfs to be y2038 safe.
Note that whenever a single call to current_time() is used to change timestamps in different inodes, it is because they share the same time granularity.

nilfs2: move ioctl interface and disk layout to uapi separately
The header file "include/linux/nilfs2_fs.h" is composed of parts for ioctl and disk format, and both are intended to be shared with user space programs.
This moves them to the uapi directory "include/uapi/linux" splitting the file to "nilfs2_api.h" and "nilfs2_ondisk.h". The following minor changes are accompanied by this migration:
- nilfs_direct_node struct in nilfs2/direct.h is converged to nilfs2_ondisk.h because it's an on-disk structure. - inline functions nilfs_rec_len_from_disk() and nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.

nilfs2: hide function name argument from nilfs_error()
Simplify nilfs_error(), an output function used to report critical issues in file system. This renames the original nilfs_error() function to __nilfs_error() and redefines it as a macro to hide its function name argument within the macro.
Every call site of nilfs_error() is changed to strip __func__ argument except nilfs_bmap_convert_error(); nilfs_bmap_convert_error() directly calls __nilfs_error() because it inherits caller's function name.

make ext2_get_page() and friends work without external serialization
Right now ext2_get_page() (and its analogues in a bunch of other filesystems) relies upon the directory being locked - the way it sets and tests Checked and Error bits would be racy without that. Switch to a slightly different scheme, _not_ setting Checked in case of failure. That way the logics becomes if Checked => OK else if Error => fail else if !validate => fail else => OK with validation setting Checked or Error on success and failure resp. and returning which one had happened. Equivalent to the current logics, but unlike the current logics not sensitive to the order of set_bit, test_bit getting reordered by CPU, etc.

mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm.
Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable.
Let's stop pretending that pages in page cache are special. They are not.
The changes are pretty straight-forward:
- <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
- page_cache_get() -> get_page();
- page_cache_release() -> put_page();
This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually.
The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later.
There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch.
