      mm/sharepool: Rename sp_mapping.flag to sp_mapping.type · ef12ea35
      由 Chen Jun 提交于 
      hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5I72Q
CVE: NA

--------------------------------

Now, sp_mapping.flag is only used to distinguish sp_mapping types.
So, 'type' are more suitable.

      mm/sharepool: Make the definitions of MMAP_SHARE_POOL_{START|16G_START} more readable · 14cd3fb0
      由 Chen Jun 提交于 
      hulk inclusion

bugzilla: https://gitee.com/openeuler/kernel/issues/I5I72Q
CVE: NA

--------------------------------

"TASK_SIZE - MMAP_SHARE_POOL_DVPP_SIZE" is puzzling.

MMAP_SHARE_POOL_START = MMAP_SHARE_POOL_END - MMAP_SHARE_POOL_SIZE and
MMAP_SHARE_POOL_16G_START = MMAP_SHARE_POOL_END - MMAP_SHARE_POOL_DVPP_SIZE
make the memory layout not unintuitive.

CVE: NA

--------------------------------

Fix a deadlock indicated below:

[  171.669844] Chain exists of:
[  171.669844]   &mm->mmap_lock --> sp_group_sem --> &spg->rw_lock
[  171.669844]
[  171.671469]  Possible unsafe locking scenario:
[  171.671469]
[  171.672121]        CPU0                    CPU1
[  171.672415]        ----                    ----
[  171.672706]   lock(&spg->rw_lock);
[  171.673114]                                lock(sp_group_sem);
[  171.673706]                                lock(&spg->rw_lock);
[  171.674208]   lock(&mm->mmap_lock);
[  171.674863]
[  171.674863]  *** DEADLOCK ***

sharepool use lock in order:
sp_group_sem --> &spg->rw_lock --> mm->mmap_lock
However, in sp_check_mmap_addr(), when mm->mmap_lock is held, it
requested sp_group_sem, which is: mm->mmap_lock --> sp_group_sem.
This causes ABBA problem.

This happens in:

The mutex protecting spm_dvpp_list has an ABBA deadlock with
spg->rw_lock. Try add a process to a sharepool group and cat
/proc/sharepool/spa_stat at the same time will reproduce the
problem.

Remove spg->rw_lock to avoid this.

CVE: NA

--------------------------------

When there are a large number of groups in the system, or with a large
number of processes in each group, "cat /proc/sharepool/proc_stat"
will encounter softlockup before all prints finished.
This is because there are too many loops in the callback function.
Remove one of the loops to reduce time cost and add a cond_resched() to
avoid this.

      mm/sharepool: delete redundant codes · cd65775f
      由 Guo Mengqi 提交于 
      hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5O5RQ
CVE: NA

--------------------------------

Notice that in sp_unshare_uva(), for authentication check, comparison
between current->tgid and spa->applier is well enough. There is no need
to check current->mm against spa->mm.

Other redundant cases:
- find_spg_node_by_spg() will never return NULL in current use context;
- spg_info_show() will not come across a group with id 0.

Therefore, delete these redundant paths.

-----------------------------------------------

In function get_process_sp_res(), spg_node can be freed by other
process, the access to spg_node->spg can cause kernel panic. Add
a pair of read lock to fix this problem.
Fix the same problem in proc_sp_group_state().
