Bug ID: 209039
Summary: getextattr(8) -x garbles non-ASCII bytes
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]

getextattr is used to print the value of an extended attribute on a file. The
-x option prints the output in hex instead of ASCII. It prints one byte at a
time, with spaces between bytes. However, when printing bytes with the high
bit set, getextattr erroneously interprets the single byte as a signed 32-bit
number.
