[LU-20019] adler32 checksum error on Linux client with kernel 6.17

• Type: Bug
• Resolution: Fixed
• Priority: Medium
• Fix Version/s: Lustre 2.18.0
• Severity: 3
• Assignee: Dongyang Li
• Reporter: Dongyang Li

Description

with the more recent kernel the client suffers from adler32 checksum errors for both read and write, as the checksum is always 1 no matter the content of the buffer.
all t10pi rpc checksum types are broken as well, because we use adler32 to calculate the checksum of the guard tags.
