* fs/ntfs3: Refactor ntfs_create_inodeKonstantin Komarov2021-10-111-3/+8
| | | | | | Set size for symlink, so we don't need to calculate it on the fly. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Refactor ntfs_readlink_hlpKonstantin Komarov2021-10-111-48/+43

* fs/ntfs3: Rework ntfs_utf16_to_nlsKonstantin Komarov2021-10-112-12/+9
| | | | | | | | | Now ntfs_utf16_to_nls takes length as one of arguments. If length of symlink > 255, then we tried to convert length of symlink +- some random number. Now 255 symbols limit was removed. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
* fs/ntfs3: Fix memory leak if fill_super failedKonstantin Komarov2021-10-111-34/+56
| | | | | | | | | | In ntfs_init_fs_context we allocate memory in fc->s_fs_info. In case of failed mount we must free it in ntfs_fill_super. We can't do it in ntfs_fs_free, because ntfs_fs_free called with fc->s_fs_info == NULL. fc->s_fs_info became NULL in sget_fc.

* fs/ntfs3: Keep prealloc for all types of filesKonstantin Komarov2021-10-111-7/+1
| | | | | | | | | | | | Before we haven't kept prealloc for sparse files because we thought that it will speed up create / write operations. It lead to situation, when user reserved some space for sparse file, filled volume, and wasn't able to write in reserved file. With this commit we keep prealloc. Now xfstest generic/274 pass.

| | | | | | | | | | | FALLOC_FL_PUNCH_HOLE isn't allowed with normal files. Filesystem must remember info about hole, but for normal file we can only zero it and forget. Fixes: 4342306f0f0d ("fs/ntfs3: Add file operations and implementation") Now xfstests generic/016 generic/021 generic/022 pass.

* fs/ntfs3: Remove locked argument in ntfs_set_eaKonstantin Komarov2021-10-051-15/+14
| | | | | | | | We always need to lock now, because locks became smaller (see d562e901f25d "fs/ntfs3: Move ni_lock_dir and ni_unlock into ntfs_create_inode"). Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

| | | | | | | | | | Now ntfs3 locks mutex for smaller time. Theoretically in successful cases those locks aren't needed at all. But proving the same for error cases is difficult.

* fs/ntfs3: Remove deprecated mount options nlsKari Argillander2021-09-231-4/+0
| | | | | | | | | | | | | Some discussion has been spoken that this deprecated mount options should be removed before 5.15 lands. This driver is not never seen day light so it was decided that nls mount option has to be removed. We have always possibility to add this if needed. One possible need is example if current ntfs driver will be taken out of kernel and ntfs3 needs to support mount options what it has.

| | | | | | | | | | | | | 'fnd' has been dereferenced several time before, so testing it here is pointless.

| | | | | | | | | | | | | | Right now sb blocksize first get initiliazed in fill_super but in can be changed in helper function. It makes more sense to that this happened only in one place. Because we move this to helper function it makes more sense that s_maxbytes will also be there.

* fs/ntfs3: Limit binary search table sizeKari Argillander2021-09-131-69/+41
| | | | | | | | | | | | | | Current binary search allocates memory for table and fill whole table before we start actual binary search. This is quite inefficient because table fill will always be O(n). Also if table is huge we need to reallocate memory which is costly. This implementation use just stack memory and always when table is full we will check if last element is <= and if not start table fill again. The idea was that it would be same cost as table reallocation.
