[LU-19050] Support long nidlists in liblustre api

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Lustre 2.17.0
• Affects Version/s: Lustre 2.16.0, Lustre 2.17.0
• Severity: 3
• Assignee: Marc Vef
• Reporter: Marc Vef

Description

Certain nid character arrays in the liblustreapi do not accommodate for nidlists larger than >256 characters due to using MAX_LINE_LEN for its size. This causes further issues in get_root_path() that can result in a buffer overflow during a string copy.
