[LU-11696] "lfs getsom" returns "24" (sizeof lustre_som_attr) to userspace

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.1
• Affects Version/s: Lustre 2.12.0
• Severity: 3
• Assignee: Qian Yingjin
• Reporter: Andreas Dilger

Description

The "lfs getsom" command always returns "24" to userspace because "rc = 24" (sizeof (struct lustre_som_attrs)) after fetching the xattr from the kernel. If the lfs_getsom()->lgetxattr() call returns a positive value, then this is the size of the xattr < sizeof(*attrs) and rc should be set to 0 in that case.
