This is done by parsing hiberfil.sys if present. + - Fix several occurences of a bug where we would perform 'var & ~const' + with a 64-bit variable and a int, i.e. 32-bit, constant. This causes + the higher order 32-bits of the 64-bit variable to be zeroed. To fix + this cast the 'const' to the same 64-bit type as 'var'. 2.1.22 - Many bug and race fixes and error handling improvements. diff --git a/fs/ntfs/dir.c b/fs/ntfs/dir.c index a56ca1821ee..46779471c54 100644 --- a/fs/ntfs/dir.c +++ b/fs/ntfs/dir.c @@ -1308,7 +1308,8 @@ find_next_index_buffer: ntfs_debug("Handling index buffer 0x%llx.", (unsigned long long)bmp_pos + cur_bmp_pos); /* If the current index buffer is in the same page we reuse the page. */ - if ((prev_ia_pos & PAGE_CACHE_MASK) != (ia_pos & PAGE_CACHE_MASK)) { + if ((prev_ia_pos & (s64)PAGE_CACHE_MASK) != + (ia_pos & (s64)PAGE_CACHE_MASK)) { prev_ia_pos = ia_pos; if (likely(ia_page != NULL)) { unlock_page(ia_page); diff --git a/fs/ntfs/inode.h b/fs/ntfs/inode.h index 6eb99777a72..3de5c023196 100644 --- a/fs/ntfs/inode.h +++ b/fs/ntfs/inode.h @@ -110,7 +110,7 @@ struct _ntfs_inode { u8 block_size_bits; /* Log2 of the above. */ u8 vcn_size_bits; /* Log2 of the above. */ } index; - struct { /* It is a compressed file or an attribute inode. */ + struct { /* It is a compressed/sparse file/attribute inode. */ s64 size; /* Copy of compressed_size from $DATA. */ u32 block_size; /* Size of a compression block diff --git a/fs/ntfs/lcnalloc.c b/fs/ntfs/lcnalloc.c index 7087b5b0e6c..a4bc07616e5 100644 --- a/fs/ntfs/lcnalloc.c +++ b/fs/ntfs/lcnalloc.c @@ -293,7 +293,7 @@ runlist_element *ntfs_cluster_alloc(ntfs_volume *vol, const VCN start_vcn, buf_size = i_size - last_read_pos; buf_size <<= 3; lcn = bmp_pos & 7; - bmp_pos &= ~7; + bmp_pos &= ~(LCN)7; ntfs_debug("Before inner while loop: buf_size %i, lcn 0x%llx, " "bmp_pos 0x%llx, need_writeback %i.", buf_size, (unsigned long long)lcn, @@ -311,7 +311,7 @@ runlist_element *ntfs_cluster_alloc(ntfs_volume *vol, const VCN start_vcn, (unsigned int)*byte); /* Skip full bytes. */ if (*byte == 0xff) { - lcn = (lcn + 8) & ~7; + lcn = (lcn + 8) & ~(LCN)7; ntfs_debug("Continuing while loop 1."); continue; } diff --git a/fs/ntfs/logfile.c b/fs/ntfs/logfile.c index e680dd0cdb6..8edb8e20fb0 100644 --- a/fs/ntfs/logfile.c +++ b/fs/ntfs/logfile.c @@ -1,7 +1,7 @@ /* * logfile.c - NTFS kernel journal handling.
