I do not know if CONFIG_PREEMPT/SMP is possible without CONFIG_MMU but the usage of task->mm in m_stop(). The task can exit/exec before we take mmap_sem, in this case m_stop() can hit NULL or unlock the wrong rw_semaphore. Also, this code uses priv->task != NULL to decide whether we need up_read/mmput. This is correct, but we will probably kill priv->task. Change m_start/m_stop to rely on IS_ERR_OR_NULL() like task_mmu.c does. Signed-off-by:

Copy-and-paste the changes from "fs/proc/task_mmu.c: shift mm_access() from m_start() to proc_maps_open()" into task_nommu.c. Change maps_open() to initialize priv->mm using proc_mem_open(), m_start() can rely on atomic_inc_not_zero(mm_users) like task_mmu.c does.

Change the main loop in m_start() to update m->version. Mostly for consistency, but this can help to avoid the same loop if the very 1st ->show() fails due to seq_overflow(). Signed-off-by:
-
Oleg Nesterov authored
Add the "last_addr" optimization back. Like before, every ->show() method checks !seq_overflow() and sets m->version = vma->vm_start. However, it also checks that m_next_vma(vma) != NULL, otherwise it sets m->version = -1 for the lockless "EOF" fast-path in m_start(). m_start() can simply do find_vma() + m_next_vma() if last_addr is not zero, the code looks clear and simple and this case is clearly separated from "scan vmas" path.

Oleg Nesterov authored
Now that m->version is gone we can cleanup m_start(). In particular, - Remove the "unsigned long" typecast, m->index can't be negative or exceed ->map_count. But lets use "unsigned int pos" to make it clear that "pos < map_count" is safe. - Remove the unnecessary "vma != NULL" check in the main loop. It can't be NULL unless we have a vm bug. - This also means that "pos < map_count" case can simply return the valid vma and avoid "goto" and subsequent checks. Signed-off-by: -

m_start() carefully documents, checks, and sets "m->version = -1" if we are going to return NULL. The only problem is that we will be never called again if m_start() returns NULL, so this is simply pointless and misleading. Otoh, ->show() methods m->version = 0 if vma == tail_vma and this is just wrong, we want -1 in this case. And in fact we also want -1 if ->vm_next == NULL and ->tail_vma == NULL. And it is not used consistently, the "scan vmas" loop in m_start() should update last_addr too. Finally, imo the whole "last_addr" logic in m_start() looks horrible. find_vma(last_addr) is called unconditionally even if we are not going to use the result. But the main problem is that this code participates in tail_vma-or-NULL mess, and this looks simply unfixable. Remove this optimization. We will add it back after some cleanups. Signed-off-by:

1. There is no reason to reset ->tail_vma in m_start(), if we return IS_ERR_OR_NULL() it won't be used. 2. m_start() also clears priv->task to ensure that m_stop() won't use the stale pointer if we fail before get_task_struct(). But this is ugly and confusing, move this initialization in m_stop(). Signed-off-by:

1. Kill the first "vma != NULL" check. Firstly this is not possible, m_next() won't be called if ->start() or the previous ->next() returns NULL. And if it was possible the 2nd "vma != tail_vma" check is buggy, we should not wrongly return ->tail_vma. 2. Make this function readable. The logic is very simple, we should return check "vma != tail" once and return "vm_next || tail_vma". Signed-off-by:

m_start() drops ->mmap_sem and does mmput() if it retuns vsyscall vma. This is because in this case m_stop()->vma_stop() obviously can't use gate_vma->vm_mm. Now that we have proc_maps_private->mm we can simplify this logic: - Change m_start() to return with ->mmap_sem held unless it returns IS_ERR_OR_NULL(). - Change vma_stop() to use priv->mm and avoid the ugly vma checks, this makes "vm_area_struct *vma" unnecessary. - This also allows m_start() to use vm_stop(). - Cleanup m_next() to follow the new locking rule. Note: m_stop() looks very ugly, and this temporary uglifies it even more. Fixed by the next change. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: -

A simple test-case from Kirill Shutemov cat /proc/self/maps >/dev/null chmod +x /proc/self/net/packet exec /proc/self/net/packet makes lockdep unhappy, cat/exec take seq_file->lock + cred_guard_mutex in the opposite order. It's a false positive and probably we should not allow "chmod +x" on proc files. Still I think that we should avoid mm_access() and cred_guard_mutex in sys_read() paths, security checking should happen at open time. Besides, this doesn't even look right if the task changes its ->mm between m_stop() and m_start(). Add the new "mm_struct *mm" member into struct proc_maps_private and change proc_maps_open() to initialize it using proc_mem_open(). Change m_start() to use priv->mm if atomic_inc_not_zero(mm_users) succeeds or return NULL (eof) otherwise. The only complication is that proc_maps_open() users should additionally do mmdrop() in fop->release(), add the new proc_map_release() helper for that. Note: this is the user-visible change, if the task execs after open("maps") the new ->mm won't be visible via this file. I hope this is fine, and this matches /proc/pid/mem bahaviour.

get_gate_vma(priv->task->mm) looks ugly and wrong, task->mm can be NULL or it can changed by exec right after mm_access(). And in theory this race is not harmless, the task can exec and then later exit and free the new mm_struct. In this case get_task_mm(oldmm) can't help, get_gate_vma(task->mm) can read the freed/unmapped memory. I think that priv->task should simply die and hold_task_mempolicy() logic can be simplified. tail_vma logic asks for cleanups too. Signed-off-by:

For now, soft lockup detector warns once for each case of process softlockup. But the thread 'watchdog/n' may not always get the cpu at the time slot between the task switch of two processes hogging that cpu to reset soft_watchdog_warn. An example would be two processes hogging the cpu. Process A causes the softlockup warning and is killed manually by a user. Process B immediately becomes the new process hogging the cpu preventing the softlockup code from resetting the soft_watchdog_warn variable. This case is a false negative of "warn only once for a process", as there may be a different process that is going to hog the cpu. Resolve this by saving/checking the task pointer of the hogging process and use that to reset soft_watchdog_warn too. [dzickus@redhat.com: update comment] Signed-off-by:

For commit ocfs2 journal, ocfs2 journal thread will acquire the mutex osb->journal->j_trans_barrier and wake up jbd2 commit thread, then it will wait until jbd2 commit thread done. In order journal mode, jbd2 needs flushing dirty data pages first, and this needs get page lock. So osb->journal->j_trans_barrier should be got before page lock. But ocfs2_write_zero_page() and ocfs2_write_begin_inline() obey this locking order, and this will cause deadlock and hung the whole cluster.

The following case may lead to o2net_wq and o2hb thread deadlock on o2hb_callback_sem. Currently there are 2 nodes say N1, N2 in the cluster. And N2 down, at the same time, N3 tries to join the cluster. So N1 will handle node down (N2) and join (N3) simultaneously. o2hb o2net_wq ->o2hb_do_disk_heartbeat ->o2hb_check_slot ->o2hb_run_event_list ->o2hb_fire_callbacks ->down_write(&o2hb_callback_sem) ->o2net_hb_node_down_cb ->flush_workqueue(o2net_wq) ->o2net_process_message ->dlm_query_join_handler ->o2hb_check_node_heartbeating ->o2hb_fill_node_map ->down_read(&o2hb_callback_sem) No need to take o2hb_callback_sem in dlm_query_join_handler, o2hb_live_lock is enough to protect live node map.

Firing quorum before connection established can cause unexpected node to reboot. Assume there are 3 nodes in the cluster, Node 1, 2, 3. Node 2 and 3 have wrong ip address of Node 1 in cluster.conf and global heartbeat is enabled in the cluster. After the heatbeats are started on these three nodes, Node 1 will reboot due to quorum fencing. It is similar case if Node 1's networking is not ready when starting the global heartbeat. The reboot is not friendly as customer is not fully ready for ocfs2 to work. Fix it by not allowing firing quorum before the connection is established. In this case, ocfs2 will wait until the wrong configuration is fixed or networking is up to continue. Also update the log to guide the user where to check when connection is not built for a long time. Signed-off-by:

According to commit 80af2588 ("fanotify: groups can specify their f_flags for new fd"), file descriptors created as part of file access notification events inherit flags from the event_f_flags argument passed to syscall fanotify_init(2)[1]. Unfortunately O_CLOEXEC is currently silently ignored. Indeed, event_f_flags are only given to dentry_open(), which only seems to care about O_ACCMODE and O_PATH in do_dentry_open(), O_DIRECT in open_check_o_direct() and O_LARGEFILE in generic_file_open(). It's a pity, since, according to some lookup on various search engines and http://codesearch.debian.net/, there's already some userspace code which use O_CLOEXEC: - in systemd's readahead[2]: fanotify_fd = fanotify_init(FAN_CLOEXEC|FAN_NONBLOCK, O_RDONLY|O_LARGEFILE|O_CLOEXEC|O_NOATIME); - in clsync[3]: #define FANOTIFY_EVFLAGS (O_LARGEFILE|O_RDONLY|O_CLOEXEC) int fanotify_d = fanotify_init(FANOTIFY_FLAGS, FANOTIFY_EVFLAGS); - in examples [4] from "Filesystem monitoring in the Linux kernel" article[5] by Aleksander Morgado: if ((fanotify_fd = fanotify_init (FAN_CLOEXEC, O_RDONLY | O_CLOEXEC | O_LARGEFILE)) < 0) Additionally, since commit 48149e9d ("fanotify: check file flags passed in fanotify_init"). having O_CLOEXEC as part of fanotify_init() second argument is expressly allowed. So it seems expected to set close-on-exec flag on the file descriptors if userspace is allowed to request it with O_CLOEXEC. But Andrew Morton raised[6] the concern that enabling now close-on-exec might break existing applications which ask for O_CLOEXEC but expect the file descriptor to be inherited across exec(). In the other hand, as reported by Mihai Dontu[7] close-on-exec on the file descriptor returned as part of file access notify can break applications due to deadlock. So close-on-exec is needed for most applications. More, applications asking for close-on-exec are likely expecting it to be enabled, relying on O_CLOEXEC being effective. If not, it might weaken their security, as noted by Jan Kara[8]. So this patch replaces call to macro get_unused_fd() by a call to function get_unused_fd_flags() with event_f_flags value as argument. This way O_CLOEXEC flag in the second argument of fanotify_init(2) syscall is interpreted and close-on-exec get enabled when requested.
