2022-09-30fs/ntfs3: Fix attr_punch_hole() null pointer derenferenceAlon Zahavi1-1/+1
The bug occours due to a misuse of `attr` variable instead of `attr_b`. `attr` is being initialized as NULL, then being derenfernced as `attr->res.data_size`. This bug causes a crash of the ntfs3 driver itself, If compiled directly to the kernel, it crashes the whole system.

2021-10-11fs/ntfs3: Keep prealloc for all types of filesKonstantin Komarov1-7/+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.

2021-09-21fs/ntfs3: Add sync flag to ntfs_sb_write_run and al_updateKonstantin Komarov1-1/+1

2021-09-16fs/ntfs3: Use min/max macros instated of ternary operatorsKari Argillander1-1/+2
We can make code little bit more readable by using min/max macros. These were found with Coccinelle. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

We have lot of unnecessary headers in these files. Remove them so that we help compiler a little bit. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2021-09-09fs/ntfs3: Convert mount options to pointer in sbiKari Argillander1-1/+1
Use pointer to mount options. We want to do this because we will use new mount api which will benefit that we have spi and mount options in different allocations. When we remount we do not have to make whole new spi it is enough that we will allocate just mount options. Please note that we can do example remount lot cleaner but things will change in next patch so this should be just functional.

2021-08-31fs/ntfs3: Rework file operationsKonstantin Komarov1-8/+9
Rename now works "Add new name and remove old name". "Remove old name and add new name" may result in bad inode if we can't add new name and then can't restore (add) old name. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2021-08-30fs/ntfs3: Restyle comments to better align with kernel-docKari Argillander1-119/+111
Capitalize comments and end with period for better reading. Also function comments are now little more kernel-doc style. This way we can easily convert them to kernel-doc style if we want. Note that these are not yet complete with this style. Example function comments start with /* and in kernel-doc style they start /**. Use imperative mood in function descriptions. Change words like ntfs -> NTFS, linux -> Linux. Use "we" not "I" when commenting code.

2021-08-27fs/ntfs3: Do not use driver own alloc wrappersKari Argillander1-3/+3
Problem with these wrapper is that we cannot take off example GFP_NOFS flag. It is not recomended use those in all places. Also if we change one driver specific wrapper to kernel wrapper then it would look really weird. People should be most familiar with kernel wrappers so let's just use those ones. Driver specific alloc wrapper also confuse some static analyzing tools, good example is example kernels checkpatch tool. After we converter these to kernel specific then warnings is showed. Following Coccinelle script was used to automate changing. virtual patch @alloc depends on patch@ expression x; expression y; @@ ( - ntfs_malloc(x) + kmalloc(x, GFP_NOFS) | - ntfs_zalloc(x) + kzalloc(x, GFP_NOFS) | - ntfs_vmalloc(x) + kvmalloc(x, GFP_NOFS) | - ntfs_free(x) + kfree(x) | - ntfs_vfree(x) + kvfree(x) | - ntfs_memdup(x, y) + kmemdup(x, y, GFP_NOFS) ) Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2021-08-27fs/ntfs3: Use kernel ALIGN macros over driver specificKari Argillander1-1/+1
The static checkers (Smatch) were complaining because QuadAlign() was buggy. If you try to align something higher than UINT_MAX it got truncated to a u32. Smatch warning was: fs/ntfs3/attrib.c:383 attr_set_size_res() warn: was expecting a 64 bit value instead of '~7' So that this will not happen again we will change all these macros to kernel made ones. This can also help some other static analyzing tools to give us better warnings. Patch was generated with Coccinelle script and after that some style issue was hand fixed.
