nfsd: remove old fault injection infrastructure

2014-08-05T14:55:10+00:00

Remove the old nfsd_for_n_state function and move nfsd_find_client higher up into the file to get rid of forward declaration. Remove the struct nfsd_fault_inject_op arguments from the operations as they are no longer needed by any of them. Finally, remove the old "standard" get and set routines, which also eliminates the client_mutex from this code. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

nfsd: add more granular locking to *_delegations fault injectors

nfsd: add more granular locking to forget_openowners fault injector

2014-08-05T14:55:08+00:00

...instead of relying on the client_mutex. Also, fix up the printk output that is generated when the file is read. It currently says that it's reporting the number of open files, but it's actually reporting the number of openowners. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

nfsd: add more granular locking to forget_locks fault injector

nfsd: add nfsd_inject_forget_clients

2014-08-05T14:55:05+00:00

...which uses the client_lock for protection instead of client_mutex. Also remove nfsd_forget_client as there are no more callers. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

nfsd: add a forget_client set_clnt routine

nfsd: add a forget_clients "get" routine with proper locking

2014-08-05T14:55:04+00:00

Add a new "get" routine for forget_clients that relies on the client_lock instead of the client_mutex. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

nfsd: abstract out the get and set routines into the fault injection ops

2014-08-05T14:55:02+00:00

Now that we've added more granular locking in other places, it's time to address the fault injection code. This code is currently quite reliant on the client_mutex for protection. Start to change this by adding a new set of fault injection op vectors. For now they all use the legacy ones. In later patches we'll add new routines that can deal with more granular locking. Also, move some of the printk routines into the callers to make the results of the operations more uniform. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

nfsd: properly handle embedded newlines in fault_injection input

2014-06-23T15:31:38+00:00

Currently rpc_pton() fails to handle the case where you echo an address into the file, as it barfs on the newline. Ensure that we NULL out the first occurrence of any newline. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields
