2016-09-19staging: lustre: obd: use proper flags for call_usermodehelperJames Simmons1-1/+1
When a parameter is permanently changed on the MGS the MGS send a changelog packet to the proper nodes that are affected by the change. Once the nodes receive the change they then call the userland utility lctl to change its local value. When calling a userland application from the kernel you specify a flag to control the interaction with the application. Originally by default the flag was set to 0 which is UMH_NO_WAIT which meant lctl was being called asynchronously. In older kernels this was fine since UHM_NO_WAIT and UHM_WAIT_PROC had nearly the same logic. This changed with newer kernels which broke updating our parameters. Plus doing a UHM_NO_WAIT doesn't report back a error if something goes wrong with lctl. The fix is to set the flag to UHM_WAIT_PROC so kernel space waits until lctl has finished and we get a proper error code if something does go wrong with lctl.

2016-09-19staging: lustre: client: Fix mkdir -i 1 from DNE2 client to DNE1 serverArtem Blagodarenko1-8/+12
After DNE phase 2 has been added to client it sends create request to slave MDT. DNT1-only server doesn't expect request to slave MDT from client. It expects only cross-mdt request from master MDT. Thus if DNE2 client tries to "mkdir -i 1" on DNE1 server, then LBUG happened. This patch adds OBD_CONNECT_DIR_STRIPE connection flag check on client side. If striped directories are not supported by server, then create requrest is sent to master MDT.

2016-09-19staging: lustre: llite: pack suppgid to MDS correctlyFan Yong2-2/+35
The ll_lookup_it() may trigger IT_OPEN RPC to open a file by name. But at that time, the client does not know the target file's GID, so it cannot pack the necessary supplementary group ID in the RPC. Because of missing the supplementary group ID, the RPC maybe fail for open permission check on the MDS. Under such case, MDS should return the target file's GID, if the current thread on the client in the right group (according to the file's GID), the client will try the IT_OPEN RPC again with the right supplementary group ID. This patch is also helpful if some other(s) changed the file's GID after current RPC sent to the MDS with the suppgid as the original GID by race.

2016-09-19staging: lustre: ptlrpc: quiet errors on initial connectionAndreas Dilger2-24/+30
It may be that a client or MDS is trying to connect to a target (OST or peer MDT) before that target is finished setup. Rather than spamming the console logs during initial connection, only print a console error message if there are repeated failures trying to connect to the target, which may indicate an error on that node.

2016-09-19staging: lustre: ldlm: revert the changes for lock canceling policyJinshan Xiong1-6/+0
The changes for LRU lock policy was introduced by commit bfae5a4e, where I was trying to revise the policy to pick locks for canceling. However, this caused two problems as mentioned in LU-5727. The first problem is that the lock can only be picked for canceling only if the number of LRU locks is over preset LRU number AND it's aged; the second problem is that mdc_cancel_weight() tends to not cancel OPEN locks, therefore open locks can be kept forever and finally exhausts memory on the MDT side. The commit 7b2d26b0 ("revert changes to ldlm_cancel_aged_policy") fixed the first problem. This patch will revert the rest of changes related to LRU policy revise.

2016-09-19staging: lustre: recovery: don't replay closed openNiu Yawei1-1/+5
To avoid scanning the replay open list every time in the ptlrpc_free_committed(), the fix of LU-2613 (4322e0f9) changed the ptlrpc_free_committed() to skip the open list unless the import generation is changed. That introduced a race which could make a closed open being replayed: 1. Application calls ll_close_inode_openhandle()-> mdc_close(), to close file, rq_replay is cleared, but the open request is still on the imp_committed_list; 2. Before the md_clear_open_replay_data() is called for close, client start replay, and that closed open will be replayed mistakenly; 3. Open replay interpret callback (mdc_replay_open) could race with the mdc_clear_open_replay_data() at the end; This patch fix the ptlrpc_free_committed() to make sure the open list is scanned on recovery to prevent the closed open request from being replayed.
