treewide: change inode->i_ino from unsigned long to u64

2026-03-06T13:31:28+00:00

On 32-bit architectures, unsigned long is only 32 bits wide, which causes 64-bit inode numbers to be silently truncated. Several filesystems (NFS, XFS, BTRFS, etc.) can generate inode numbers that exceed 32 bits, and this truncation can lead to inode number collisions and other subtle bugs on 32-bit systems. Change the type of inode->i_ino from unsigned long to u64 to ensure that inode numbers are always represented as 64-bit values regardless of architecture. Update all format specifiers treewide from %lu/%lx to %llu/%llx to match the new type, along with corresponding local variable types. This is the bulk treewide conversion. Earlier patches in this series handled trace events separately to allow trace field reordering for better struct packing on 32-bit.

integrity: check the return value of audit_log_start()

2022-02-02T16:44:23+00:00

audit_log_start() returns audit_buffer pointer on success or NULL on error, so it is better to check the return value of it. Fixes: 3323eec921ef ("integrity: IMA as an integrity service provider") Signed-off-by: Xiaoke Wang Cc: Reviewed-by: Paul Moore Signed-off-by: Mimi Zohar

integrity: Add errno field in audit message

2020-07-17T01:48:11+00:00

Error code is not included in the audit messages logged by the integrity subsystem. Define a new function integrity_audit_message() that takes error code in the "errno" parameter. Add "errno" field in the audit messages logged by the integrity subsystem and set the value passed in the "errno" parameter.

audit: use inline function to get audit context

Recognizing that the audit context is an internal audit value, use an access function to retrieve the audit context pointer for the task rather than reaching directly into the task struct to get it.

integrity: fix checkpatch errors

2014-03-07T17:15:45+00:00

Between checkpatch changes (eg. sizeof) and inconsistencies between Lindent and checkpatch, unfixed checkpatch errors make it difficult to see new errors. This patch fixes them. Some lines with over 80 chars remained unchanged to improve code readability. The "extern" keyword is removed from internal evm.h to make it consistent with internal ima.h.
