* [PATCH] e2fsprogs: fix to use inode i_blocks correctly @ 2019-12-30 11:36 Wang Shilong 2019-12-30 15:19 ` Theodore Y. Ts'o 0 siblings, 1 reply; 5+ messages in thread From: Wang Shilong @ 2019-12-30 11:36 UTC (permalink / raw) To: linux-ext4; +Cc: lixi, adilger, dongyangli, Wang Shilong From: Wang Shilong <wshilong@ddn.com> According to following logic: "If the huge_file feature flag is not set on the filesystem, the file consumes i_blocks_lo 512-byte blocks on disk. If huge_file is set and EXT4_HUGE_FILE_FL is NOT set in inode.i_flags, then the file consumes i_blocks_lo + (i_blocks_hi << 32) 512-byte blocks on disk. If huge_file is set and EXT4_HUGE_FILE_FL IS set in inode.i_flags, then this file consumes (i_blocks_lo + i_blocks_hi << 32) filesystem blocks on disk." blocks_from_inode() did not return wrong inode blocks, and ext2fs_inode_i_blocks() is not taking EXT4_HUGE_FILE_FL into account at all, while the some callers deal it correctly, some not.

First of all, it's in a shared library, so if there are any binaries which were expecting the old behavior, that could get surprising. Secondly, its name is confusing and so we're better off creating a new function ext2fs_get_stat_i_blocks() which makes it clear that we function is using units of 512 byte sectors, instead of either the file system block size, or the raw i_blocks value from the inode. Two other things about your patch. First of all, the filefrag command in debugfs was intended to print the number of file system blocks, so it was correct as written. Secondly, please note the blkcnt_t is a signed type (because the block iterator functions use negative values to indicate various kinds of metadata blocks), while blk64_t is an unsigned type. So using blkcnt_t as a temporary value and returning it in a function which has a return type of blk64_t will (righly) trigger compiler warnings. Here's the patch I've checked into the maint branch of e2fsprogs to address the issue you've identified. - Ted ^ permalink raw reply [flat|nested] 5+ messages in thread

Oops, here you go. - Ted commit c90cea86eeef89f29f7bd5535fbaa5809a812cc7 Author: Theodore Ts'o <tytso@mit.edu> Date: Mon Dec 30 10:12:58 2019 -0500 ext2fs: add ext2fs_get_stat_i_blocks() function The function ext2fs_inode_i_blocks() is a bit confusing whether it is returning the inode's i_blocks value, or whether it is returning the value ala the stat(2) system call, which returns i_blocks in units of 512 byte sectors. This caused ext2fs_inode_i_blocks() to be incorrectly used in fuse2fs and the function quota_compute_usage(). To address this, we add a new function, ext2fs_get_stat_i_blocks() which is clearly labelled what it is returning, and use it in fuse2fs and quota_compute_usage(). It's also a bit more convenient to use it in e2fsck, so use it there too.
