2019-07-03ext2: Use kmemdup rather than duplicating its implementationFuqian Huang1-2/+1
kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memset, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memset.

2019-01-31ext2: Fix underflow in ext2_max_size()Jan Kara1-14/+25
When ext2 filesystem is created with 64k block size, ext2_max_size() will return value less than 0. Also, we cannot write any file in this fs since the sb->maxbytes is less than 0. The core of the problem is that the size of block index tree for such large block size is more than i_blocks can carry. So fix the computation to count with this possibility. File size limits computed with the new function for the full range of possible block sizes look like: bits file_size 10 17247252480 11 275415851008 12 2196873666560 13 2197948973056 14 2198486220800 15 2198754754560 16 2198888906752 CC: stable@vger.kernel.org Reported-by: yangerkun <yangerkun@huawei.com> Signed-off-by: Jan Kara <jack@suse.cz>

2018-08-17dax: remove VM_MIXEDMAP for fsdax and device daxDave Jiang1-1/+0
This patch is reworked from an earlier patch that Dan has posted: https://patchwork.kernel.org/patch/10131727/ VM_MIXEDMAP is used by dax to direct mm paths like vm_normal_page() that the memory page it is dealing with is not typical memory from the linear map. The get_user_pages_fast() path, since it does not resolve the vma, is already using {pte,pmd}_devmap() as a stand-in for VM_MIXEDMAP, so we use that as a VM_MIXEDMAP replacement in some locations. In the cases where there is no pte to consult we fallback to using vma_is_dax() to detect the VM_MIXEDMAP special case. Now that we have explicit driver pfn_t-flag opt-in/opt-out for get_user_pages() support for DAX we can stop setting VM_MIXEDMAP. This also means we no longer need to worry about safely manipulating vm_flags in a future where we support dynamically changing the dax mode of a file. DAX should also now be supported with madvise_behavior(), vma_merge(), and copy_page_range(). This patch has been tested against ndctl unit test. It has also been tested against xfstests commit: 625515d using fake pmem created by memmap and no additional issues have been observed.

2018-06-27ext2: use ktime_get_real_seconds for timestampsArnd Bergmann2-4/+5
get_seconds() is deprecated because of the y2038 overflow, so users should migrate to 64-bit timestamps using ktime_get_real_seconds(). In ext2, the timestamps in the superblock and in the inode are all limited to 32-bit, and this won't get fixed, so let's just stop using the deprecated interface and keep truncating. All users of ext2 should migrate to ext4 before 2038 to prevent this from causing problems. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jan Kara <jack@suse.cz>
2018-06-20ext2: add warning when specifying nocheck optionChengguang Xu2-5/+3
The option nocheck(nocheck/check=none) is useless but considering backwards compatibility it's better to print warning for a while before completely remove from the code. This patch add proper warning message for option 'nocheck' and remove unnecessary comment/function declaration which is used for removed option 'check'.
