[PATCH openEuler-1.0-LTS] nilfs2: fix data corruption in dsync block recovery for small block sizes

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.307 commit 5278c3eb6bf5896417572b52adb6be9d26e92f65 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2FH CVE: CVE-2024-26697 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 67b8bcbaed4777871bb0dcc888fb02a614a98ab1 upstream. The helper function nilfs_recovery_copy_block() of nilfs_recovery_dsync_blocks(), which recovers data from logs created by data sync writes during a mount after an unclean shutdown, incorrectly calculates the on-page offset when copying repair data to the file's page cache. In environments where the block size is smaller than the page size, this flaw can cause data corruption and leak uninitialized memory bytes during the recovery process. Fix these issues by correcting this byte offset calculation on the page.
