Hello Mark Tinguely,
The patch 2a84108fe275: "xfs: free the list of recovery items on
error" from Oct 2, 2013, leads to the following
static checker warning: "fs/xfs/xfs_log_recover.c:3621
xlog_recover_process_data()
warn: 'trans' was already freed."
fs/xfs/xfs_log_recover.c
3589 switch (flags) {
3590 case XLOG_COMMIT_TRANS:
3591 error = xlog_recover_commit_trans(log,
3592 trans, pass);
xlog_recover_commit_trans() frees trans on the success path and on some
failure paths.
3593 break;
3594 case XLOG_UNMOUNT_TRANS:
3595 error = xlog_recover_unmount_trans(log, trans);
3596 break;
3597 case XLOG_WAS_CONT_TRANS:
3598 error = xlog_recover_add_to_cont_trans(log,
3599 trans, dp,
3600 be32_to_cpu(ohead->oh_len));
3601 break;
3602 case XLOG_START_TRANS:
3603 xfs_warn(log->l_mp, "%s: bad transaction",
3604 __func__);
3605 ASSERT(0);
3606 error = XFS_ERROR(EIO);
3607 break;
3608 case 0:
3609 case XLOG_CONTINUE_TRANS:
3610 error = xlog_recover_add_to_trans(log, trans,
3611 dp, be32_to_cpu(ohead->oh_len));
3612 break;
3613 default:
3614 xfs_warn(log->l_mp, "%s: bad flag 0x%x",
3615 __func__, flags);
3616 ASSERT(0);
3617 error = XFS_ERROR(EIO);
3618 break;
3619 }
3620 if (error) {
3621 xlog_recover_free_trans(trans);
Double free?
3622 return error;
3623 }
regards,
dan carpenter
