Call fiemap ioctl(2) with given start offset as well as an desired mapping range should show extents if possible. However, we somehow figure out the end offset of mapping via 'mapping_end -= cpos' before iterating the extent records which would cause problems if the given fiemap length is too small to a cluster size, e.g, Cluster size 4096: debugfs.ocfs2 1.6.3 Block Size Bits: 12 Cluster Size Bits: 12 The extended fiemap test utility From David: https://gist.github.com/anonymous/6172331 # dd if=/dev/urandom of=/ocfs2/test_file bs=1M count=1000 # ./fiemap /ocfs2/test_file 4096 10 start: 4096, length: 10 File /ocfs2/test_file has 0 extents: # Logical Physical Length Flags ^^^^^ <-- No extent is shown In this case, at ocfs2_fiemap(): cpos == mapping_end == 1. Hence the loop of searching extent records was not executed at all. This patch remove the in question 'mapping_end -= cpos', and loops until the cpos is larger than the mapping_end as usual. # ./fiemap /ocfs2/test_file 4096 10 start: 4096, length: 10 File /ocfs2/test_file has 1 extents: # Logical Physical Length Flags 0: 0000000000000000 0000000056a01000 0000000006a00000 0000 Signed-off-by:Jie Liu <jeff.liu@oracle.com> Reported-by:

In o2hb_shutdown_slot() and o2hb_check_slot(), since event is defined as local, it is only valid during the call stack. So the following tiny race case may happen in a multi-volumes mounted environment: o2hb-vol1 o2hb-vol2 1) o2hb_shutdown_slot allocate local event1 2) queue_node_event add event1 to global o2hb_node_events 3) o2hb_shutdown_slot allocate local event2 4) queue_node_event add event2 to global o2hb_node_events 5) o2hb_run_event_list delete event1 from o2hb_node_events 6) o2hb_run_event_list event1 empty, return 7) o2hb_shutdown_slot event1 lifecycle ends 8) o2hb_fire_callbacks event1 is already *invalid* This patch lets it wait on o2hb_callback_sem when another thread is firing callbacks. And for performance consideration, we only call o2hb_run_event_list when there is an event queued. Signed-off-by:Joyce <xuejiufei@huawei.com> Signed-off-by:

In ocfs2_reflink_xattr_rec(), meta_ac and data_ac are allocated by calling ocfs2_lock_reflink_xattr_rec_allocators(). Once an error occurs when allocating *data_ac, it frees *meta_ac which is allocated before. Here it mistakenly sets meta_ac to NULL but *meta_ac. Then ocfs2_reflink_xattr_rec() will try to free meta_ac again which is already invalid. Signed-off-by:

dlm_do_local_recovery_cleanup() should force clean refmap if the owner of lockres is UNKNOWN. Otherwise node may hang when umounting filesystems. Here's the situation: Node1 Node2 dlmlock() -> dlm_get_lock_resource() send DLM_MASTER_REQUEST_MSG to other nodes. trying to master this lockres, return MAYBE. selected as the master of lockresA, set mle->master to Node1, and do assert_master, send DLM_ASSERT_MASTER_MSG to Node2. Node 2 has interest on lockresA and return DLM_ASSERT_RESPONSE_MASTERY_REF then something happened and Node2 crashed. Receiving DLM_ASSERT_RESPONSE_MASTERY_REF, set Node2 into refmap, and keep sending DLM_ASSERT_MASTER_MSG to other nodes o2hb found node2 down, calling dlm_hb_node_down() --> dlm_do_local_recovery_cleanup() the master of lockresA is still UNKNOWN, no need to call dlm_free_dead_locks(). Set the master of lockresA to Node1, but Node2 stills remains in refmap. When Node1 umount, it found that the refmap of lockresA is not empty and attempted to migrate it to Node2, But Node2 is already down, so umount hang, trying to migrate lockresA again and again.

There is an issue in reserving and claiming space for localalloc, When localalloc space is not enough, it would claim space from global_bitmap. And if there is not enough free space in global_bitmap, the size of claiming space would set to half of orignal size and retry. The issue is as follows: osb->local_alloc_bits is set to half of orignal size in ocfs2_recalc_la_window(), but ac->ac_bits_wanted is set to osb->local_alloc_default_bits which is not changed. localalloc always reserves and claims local_alloc_default_bits space and returns ENOSPC. So, ac->ac_bits_wanted should be osb->local_alloc_bits which would be changed. Signed-off-by:

dlm_request_all_locks() should deal with the status sent from target node if DLM_LOCK_REQUEST_MSG is sent successfully, or recovery master will fall into endless loop, waiting for other nodes to send locks and DLM_RECO_DATA_DONE_MSG to me. NodeA NodeB selected as recovery master dlm_remaster_locks() ->dlm_request_all_locks() send DLM_LOCK_REQUEST_MSG to nodeA It happened that NodeA cannot alloc memory when it processes this message. dlm_request_all_locks_handler() do not queue dlm_request_all_locks_worker and returns -ENOMEM. It will never send locks and DLM_RECO_DATA_DONE_MSG to NodeB. NodeB do not deal with the status sent from nodeA, and will fall in endless loop waiting for the recovery state of NodeA to be changed.

The issue scenario is as following: When fallocating a very large disk space for a small file, __ocfs2_extend_allocation attempts to get a very large transaction. For some journal sizes, there may be not enough room for this transaction, and the fallocate will fail. The patch below extends & restarts the transaction as necessary while allocating space, and should work with even the smallest journal. This patch refers ext4 resize.

do_fork() denies CLONE_THREAD | CLONE_PARENT if NEWUSER | NEWPID. Then later copy_process() denies CLONE_SIGHAND if the new process will be in a different pid namespace (task_active_pid_ns() doesn't match current->nsproxy->pid_ns). This looks confusing and inconsistent. CLONE_NEWPID is very similar to the case when ->pid_ns was already unshared, we want the same restrictions so copy_process() should also nack CLONE_PARENT. And it would be better to deny CLONE_NEWUSER && CLONE_SIGHAND as well just for consistency. Kill the "CLONE_NEWUSER | CLONE_NEWPID" check in do_fork() and change copy_process() to do the same check along with ->pid_ns check we already have. Signed-off-by:

Commit 8382fcac ("pidns: Outlaw thread creation after unshare(CLONE_NEWPID)") nacks CLONE_NEWPID if the forking process unshared pid_ns. This is correct but unnecessary, copy_pid_ns() does the same check. Remove the CLONE_NEWPID check to cleanup the code and prepare for the next change. Test-case: static int child(void *arg) { return 0; } static char stack[16 * 1024]; int main(void) { pid_t pid; assert(unshare(CLONE_NEWUSER | CLONE_NEWPID) == 0); pid = clone(child, stack + sizeof(stack) / 2, CLONE_NEWPID | SIGCHLD, NULL); assert(pid < 0 && errno == EINVAL); return 0; } clone(CLONE_NEWPID) correctly fails with or without this change.

Commit 8382fcac ("pidns: Outlaw thread creation after unshare(CLONE_NEWPID)") nacks CLONE_VM if the forking process unshared pid_ns, this obviously breaks vfork: int main(void) { assert(unshare(CLONE_NEWUSER | CLONE_NEWPID) == 0); assert(vfork() >= 0); _exit(0); return 0; } fails without this patch. Change this check to use CLONE_SIGHAND instead. This also forbids CLONE_THREAD automatically, and this is what the comment implies. We could probably even drop CLONE_SIGHAND and use CLONE_THREAD, but it would be safer to not do this. The current check denies CLONE_SIGHAND implicitely and there is no reason to change this. Eric said "CLONE_SIGHAND is fine. CLONE_THREAD would be even better. Having shared signal handling between two different pid namespaces is the case that we are fundamentally guarding against."

The enablement of that was supposed to be part of the x86 spinlock merge in commit 816434ec ("The biggest change here are paravirtualized ticket spinlocks (PV spinlocks), which bring a nice speedup on various benchmarks...") but unfortunatly it would cause hang when booting Xen PVHVM guests.

When adding cpuidle support to pSeries, we introduced two regressions: - The new cpuidle backend driver only works under hypervisors supporting the "SLPLAR" option, which isn't the case of the old POWER4 hypervisor and the HV "light" used on js2x blades - The cpuidle driver registers fairly late, meaning that for a significant portion of the boot process, we end up having all threads spinning. This slows down the boot process and increases the overall resource usage if the hypervisor has shared processors. This fixes both by implementing a "default" idle that will cede to the hypervisor when possible, in a very simple way without all the bells and whisles of cpuidle.
