  "message": "fsck.f2fs: fix to avoid selecting current section in find_next_free_block\n\nIn find_next_free_block(), when searching for a free block or allocating a\nnew section, it checks:\n\n\tif (!(get_sb(feature) \u0026 F2FS_FEATURE_RO) \u0026\u0026\n\t\t\t\t\tIS_CUR_SEGNO(sbi, segno))\n\t\tgoto next_segment;\n\nHowever, when large section is enabled (segs_per_sec \u003e 1), checking only\nIS_CUR_SEGNO(sbi, segno) is insufficient. If segment 0 of a section is\nempty, but segment 1 is an active curseg (e.g. CURSEG_WARM_NODE),\nIS_CUR_SEGNO(sbi, segno) evaluates to false.\n\nConsequently, find_next_free_block() can treat the section as completely\nfree and call set_section_type(sbi, segno, want_type). This overwrites the\nsegment type of all segments in the section, clobbering active curseg\nsegments (e.g. from NODE to DATA) and leading to an assertion crash in\nupdate_data_blkaddr():\n\n  [update_data_blkaddr:2527] NAT and SIT is inconsistent: ino: 4, nid: 23, blkaddr: 21925780, segtype: 1\n  [ASSERT] (update_data_blkaddr:2529) 0\n\nFix this by using IS_CUR_SECNO(sbi, GET_SEC_FROM_SEG(sbi, segno)) to ensure\nthat any segment belonging to an active current section is skipped.\n\nSigned-off-by: Chao Yu \u003cchao@kernel.org\u003e\nSigned-off-by: Jaegeuk Kim \u003cjaegeuk@kernel.org\u003e\n",
