Add support for setxattr and listxattr system calls by celinehoang177 · Pull Request #986 · Lind-Project/lind-wasm

celinehoang177 · 2026-03-27T01:39:15Z

Implements support for setxattr() and listxattr() system calls in Lind-Wasm, enabling compatibility with Python 3.14.3 and other applications that use extended file attributes.

Changes:

Implements setxattr_syscall() (Linux x86_64 syscall Add individual contact infos to Team page #188) to set extended attributes on files
Implements listxattr_syscall() (Linux x86_64 syscall Add files for PR Checklist comment via github workflows #194) to list extended attributes on files
Registers both syscalls in the SYSCALL_TABLE for both rawposix and wasmtime runtimes
Properly converts paths to the host namespace and handles errno conversions

Closes #889

+    } else {
+        sc_convert_buf(list_arg, list_cageid, cageid) as *mut libc::c_char
+    };
+    let size = sc_convert_sysarg_to_usize(size_arg, size_cageid, cageid);


In the earlier line, guest memory pointers are translated using sc_convert_buf without validating the guest's provided size argument. This allows a malicious guest to allocate a tiny buffer but pass a massive size, tricking the host kernel into writing outside the guest's memory boundaries (a buffer overflow).

Proposed Fix: We need to add a bounds check to validate that the entire contiguous memory region from pointer to pointer + size resides completely within the allowed cage memory. (pointer is list_arg).

+    } else {
+        sc_convert_buf(value_arg, value_cageid, cageid) as *const libc::c_void
+    };
+    let size = sc_convert_sysarg_to_usize(size_arg, size_cageid, cageid);


Similar to the comment for listxattr, there can be an out-of-bounds read here. We need to check if pointer + size is within the allowed cage memory.

If the guest allocates a 5-byte buffer containing "hello", but calls setxattr with a size of 1000, the host kernel will read 1000 bytes starting from that pointer and save it to the file's extended attributes. The guest just forced the host kernel to read 995 bytes of adjacent memory and save it to the disk. The guest can then read that file's extended attributes to steal the host's memory.

+    if ret < 0 {
+        let errno = get_errno();
+        return handle_errno(errno, "listxattr");
+    }


The setxattr and listxattr implementations allow the guest to operate on arbitrary xattr namespaces. Since the host kernel evaluates these calls using the sandbox runtime's privileges, a malicious guest can write to security.* attributes (e.g. security.capability to grant root capabilities) or modify ACLs via system.* — fully bypassing host access controls. All xattr operations must be restricted to the user.* namespace, with anything else rejected at the shim layer.
