The reply parsing code attempts to decode the GETATTR response even if the DELEGRETURN portion of the compound returned an error. The GETATTR response won't actually exist if that's the case and we're asking the parser to read past the end of the response. This bug is fairly benign. The parser catches this without reading past the end of the response and decode_getfattr returns -EIO. Earlier kernels however had decode_op_hdr using the READ_BUF macro, and this bug would make this printk pop any time the client got an error from a delegreturn: kernel: decode_op_hdr: reply buffer overflowed in line XXXX More recent kernels seem to have replaced this printk with a dprintk.
