• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.11.0
• Severity: 3

Description

An extra '&' was in lod_declare_update_plain () as follows:

comp_v1 = (struct lov_comp_md_v1 *)&info->lti_buf.lb_buf;

This will cause invalid memory region to be accessed in replay path.

Jinshan,

Is this needed for master or has it already been incorporated? I see it only exists on the flr branch.

Thanks.
Joe
