2021-08-30fs/ntfs3: Restyle comments to better align with kernel-docKari Argillander21-2070/+1987
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: Fix error handling in indx_insert_into_root()Dan Carpenter1-20/+16
There are three bugs in this code: 1) If indx_get_root() fails, then return -EINVAL instead of success. 2) On the "/* make root external */" -EOPNOTSUPP; error path it should free "re" but it has a memory leak. 3) If indx_new() fails then it will lead to an error pointer dereference when we call put_indx_node(). I've re-written the error handling to be more clear.

The ntfs_get_ea() function returns negative error codes or on success it returns the length. In the original code a zero length return was treated as -ENODATA and results in a NULL return. But it should be treated as an invalid length and result in an PTR_ERR(-EINVAL) return.

2021-08-27fs/ntfs3: Do not use driver own alloc wrappersKari Argillander16-194/+188
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 Argillander13-67/+56
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. Coccinelle script: virtual patch @alloc depends on patch@ expression x; @@ ( - #define QuadAlign(n) (((n) + 7u) & (~7u)) | - QuadAlign(x) + ALIGN(x, 8) | - #define IsQuadAligned(n) (!((size_t)(n)&7u)) | - IsQuadAligned(x) + IS_ALIGNED(x, 8) | - #define Quad2Align(n) (((n) + 15u) & (~15u)) | - Quad2Align(x) + ALIGN(x, 16) | - #define IsQuad2Aligned(n) (!((size_t)(n)&15u)) | - IsQuad2Aligned(x) + IS_ALIGNED(x, 16) | - #define Quad4Align(n) (((n) + 31u) & (~31u)) | - Quad4Align(x) + ALIGN(x, 32) | - #define IsSizeTAligned(n) (!((size_t)(n) & (sizeof(size_t) - 1))) | - IsSizeTAligned(x) + IS_ALIGNED(x, sizeof(size_t)) | - #define DwordAlign(n) (((n) + 3u) & (~3u)) | - DwordAlign(x) + ALIGN(x, 4) | - #define IsDwordAligned(n) (!((size_t)(n)&3u)) | - IsDwordAligned(x) + IS_ALIGNED(x, 4) | - #define WordAlign(n) (((n) + 1u) & (~1u)) | - WordAlign(x) + ALIGN(x, 2) | - #define IsWordAligned(n) (!((size_t)(n)&1u)) | - IsWordAligned(x) + IS_ALIGNED(x, 2) | ) Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

2021-08-20hugetlb: don't pass page cache pages to restore_reserve_on_errorMike Kravetz1-5/+14
syzbot hit kernel BUG at fs/hugetlbfs/inode.c:532 as described in [1]. This BUG triggers if the HPageRestoreReserve flag is set on a page in the page cache. It should never be set, as the routine huge_add_to_page_cache explicitly clears the flag after adding a page to the cache. The only code other than huge page allocation which sets the flag is restore_reserve_on_error. It will potentially set the flag in rare out of memory conditions. syzbot was injecting errors to cause memory allocation errors which exercised this specific path. The code in restore_reserve_on_error is doing the right thing. However, there are instances where pages in the page cache were being passed to restore_reserve_on_error. This is incorrect, as once a page goes into the cache reservation information will not be modified for the page until it is removed from the cache. Error paths do not remove pages from the cache, so even in the case of error, the page will remain in the cache and no reservation adjustment is needed. Modify routines that potentially call restore_reserve_on_error with a page cache page to no longer do so. Note on fixes tag: Prior to commit 846be08578ed ("mm/hugetlb: expand restore_reserve_on_error functionality") the routine would not process page cache pages because the HPageRestoreReserve flag is not set on such pages. Therefore, this issue could not be trigggered. The code added by commit 846be08578ed ("mm/hugetlb: expand restore_reserve_on_error functionality") is needed and correct. It exposed incorrect calls to restore_reserve_on_error which is the root cause addressed by this commit.

2021-08-20kfence: fix is_kfence_address() for addresses below KFENCE_POOL_SIZEMarco Elver1-3/+4
Originally the addr != NULL check was meant to take care of the case where __kfence_pool == NULL (KFENCE is disabled). However, this does not work for addresses where addr > 0 && addr < KFENCE_POOL_SIZE. This can be the case on NULL-deref where addr > 0 && addr < PAGE_SIZE or any other faulting access with addr < KFENCE_POOL_SIZE. While the kernel would likely crash, the stack traces and report might be confusing due to double faults upon KFENCE's attempt to unprotect such an address. Fix it by just checking that __kfence_pool != NULL instead.

2021-08-20mm: vmscan: fix missing psi annotation for node_reclaim()Johannes Weiner1-0/+3
In a debugging session the other day, Rik noticed that node_reclaim() was missing memstall annotations. This means we'll miss pressure and lost productivity resulting from reclaim on an overloaded local NUMA node when vm.zone_reclaim_mode is enabled. There haven't been any reports, but that's likely because vm.zone_reclaim_mode hasn't been a commonly used feature recently, and the intersection between such setups and psi users is probably nil. But secondary memory such as CXL-connected DIMMS, persistent memory etc, and the page demotion patches that handle them (https://lore.kernel.org/lkml/20210401183216.443C4443@viggo.jf.intel.com/) could soon make this a more common codepath again.

2021-08-20mm/hwpoison: retry with shake_page() for unhandlable pagesNaoya Horiguchi1-3/+9
HWPoisonHandlable() sometimes returns false for typical user pages due to races with average memory events like transfers over LRU lists. This causes failures in hwpoison handling. There's retry code for such a case but does not work because the retry loop reaches the retry limit too quickly before the page settles down to handlable state. Let get_any_page() call shake_page() to fix it.

2021-08-20mm: memcontrol: fix occasional OOMs due to proportional memory.low reclaimJohannes Weiner2-22/+34
We've noticed occasional OOM killing when memory.low settings are in effect for cgroups. This is unexpected and undesirable as memory.low is supposed to express non-OOMing memory priorities between cgroups. The reason for this is proportional memory.low reclaim. When cgroups are below their memory.low threshold, reclaim passes them over in the first round, and then retries if it couldn't find pages anywhere else. But when cgroups are slightly above their memory.low setting, page scan force is scaled down and diminished in proportion to the overage, to the point where it can cause reclaim to fail as well - only in that case we currently don't retry, and instead trigger OOM. To fix this, hook proportional reclaim into the same retry logic we have in place for when cgroups are skipped entirely. This way if reclaim fails and some cgroups were scanned with diminished pressure, we'll try another full-force cycle before giving up and OOMing.

2021-08-20mm/page_alloc: don't corrupt pcppage_migratetypeDoug Berger1-13/+12
When placing pages on a pcp list, migratetype values over MIGRATE_PCPTYPES get added to the MIGRATE_MOVABLE pcp list. However, the actual migratetype is preserved in the page and should not be changed to MIGRATE_MOVABLE or the page may end up on the wrong free_list. The impact is that HIGHATOMIC or CMA pages getting bulk freed from the PCP lists could potentially end up on the wrong buddy list. There are various consequences but minimally NR_FREE_CMA_PAGES accounting could get screwed up.
