[LU-5369] servers should reject invalid FIDs, requests, ...

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Lustre 2.15.0
• Affects Version/s: Lustre 2.7.0
• Labels: fault mdt medium
• Severity: 3
• Assignee: Yang Sheng
• Reporter: John Hammond

Description

As a cheap way of approximating the fuzzy requests send by old and big endian clients I added some simple OBD_FAIL_CHECK() based corruption of mdt_body and mdt_rec_reint. (See the attached patch). Then I flipped the fail loc on an off while doing various file systemey things to my file system.

Here are some crashes. A few require removing previous assertions to be reachable.
