This can lead to NULL pointer\ndereferences or unexpected behavior when these strings are processed\ndownstream, especially in utility functions like erofs_fspath().\n\nSpecifically, erofs_make_empty_root_inode() in lib/inode.c assigned\nthe result of strdup(\"/\") to root-\u003ei_srcpath without validation. If\nthis allocation failed, subsequent calls to erofs_fspath(inode-\u003ei_srcpath)\nwould attempt to dereference a NULL pointer (or an offset from NULL),\npotentially causing a crash or memory safety issues.\n\nThis patch addresses these issues by:\n1. Adding proper NULL checks for strdup() in erofs_make_empty_root_inode()\n (lib/inode.c) and erofs_rebuild_load_tree() (lib/rebuild.c). If\n allocation fails, the functions now correctly return -ENOMEM.\n2. Hardening erofs_fspath() in lib/config.c to gracefully handle NULL\n inputs. It now returns an empty string instead of attempting to\n dereference the pointer, providing a robust fallback for memory\n exhaustion scenarios.\n3. Fixing unchecked strdup() and strndup() calls in the S3 remote\n backend (lib/remotes/s3.c) and mkfs (mkfs/main.c).\n\nThese changes improve the overall robustness and reliability of the\nerofs-utils suite, particularly when operating under memory pressure.\n\nDetailed changes:\n- lib/inode.c: Check strdup(\"/\") in erofs_make_empty_root_inode;\n call erofs_iput() and return ERR_PTR(-ENOMEM) on failure.\n- lib/rebuild.c: Check strdup(\"/\") in erofs_rebuild_load_tree;\n return -ENOMEM on failure.\n- lib/config.c: Add NULL check to erofs_fspath().\n- mkfs/main.c: Check strdup(extraopts) in mkfs_parse_one_compress_alg.\n- lib/remotes/s3.c: Check strdup() in s3erofs_parse_list_objects_one()\n and s3erofs_create_object_iterator().

The real address is only\nknown after erofs_mkfs_dump_blobs applies remapped_base, so a chunk\nthat lands above UINT32_MAX after remapping may not get flagged at all,\nproducing a corrupt image.\n\nFix this by introducing erofs_inode_fixup_chunkformat() which walks\nthe chunk array after remapped_base is finalized and sets the 48-bit\nflag if any chunk address exceeds UINT32_MAX. The fixup is called from\nerofs_iflush so that the correct chunkformat is written into the\non-disk inode header. Both blob chunks (remapped_base + chunk-\u003eblkaddr)\nand device chunks (chunk-\u003eblkaddr directly) are handled.\n\nSigned-off-by: Puneeth Aditya \u003cmyakampuneeth@gmail.com\u003e\nLink: https://lore.kernel.org/r/20260225073943.11361-1-myakampuneeth@gmail.com\nSigned-off-by: Gao Xiang \u003chsiangkao@linux.alibaba.com\u003e\n" } ], "next": "2cd511441c2cbdade81f7b6fb6575eef7d8452a1" }
