2015-04-23nfs: remove WARN_ON_ONCE from nfs_direct_good_bytesPeng Tao1-2/+0

2015-04-23nfs: fix DIO good bytes calculationPeng Tao1-12/+17
For direct read that has IO size larger than rsize, we'll split it into several READ requests and nfs_direct_good_bytes() would count completed bytes incorrectly by eating last zero count reply. Fix it by handling mirror and non-mirror cases differently such that we only count mirrored writes differently. This fixes 5fadeb47("nfs: count DIO good bytes correctly with mirroring").

2015-04-23nfs: Fetch MOUNTED_ON_FILEID when updating an inodeAnna Schumaker2-2/+16
2ef47eb1 (NFS: Fix use of nfs_attr_use_mounted_on_fileid()) was a good start to fixing a circular directory structure warning for NFS v4 "junctioned" mountpoints. Unfortunately, further testing continued to generate this error. My server is configured like this: anna@nfsd ~ % df Filesystem Size Used Avail Use% Mounted on /dev/vda1 9.1G 2.0G 6.5G 24% / /dev/vdc1 1014M 33M 982M 4% /exports /dev/vdc2 1014M 33M 982M 4% /exports/vol1 /dev/vdc3 1014M 33M 982M 4% /exports/vol1/vol2 anna@nfsd ~ % cat /etc/exports /exports/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/ *(rw,async,no_subtree_check,no_root_squash) /exports/vol1/vol2 *(rw,async,no_subtree_check,no_root_squash) I've been running chown across the entire mountpoint twice in a row to hit this problem. The first run succeeds, but the second one fails with the circular directory warning along with: anna@client ~ % dmesg [Apr 3 14:28] NFS: server 192.168.100.204 error: fileid changed fsid 0:39: expected fileid 0x100080, got 0x80 WHere 0x80 is the mountpoint's fileid and 0x100080 is the mounted-on fileid. This patch fixes the issue by requesting an updated mounted-on fileid from the server during nfs_update_inode(), and then checking that the fileid stored in the nfs_inode matches either the fileid or mounted-on fileid returned by the server.

2015-04-23sunrpc: make debugfs file creation failure non-fatalJeff Layton5-47/+41
v2: gracefully handle the case where some dentry pointers end up NULL and be more dilligent about zeroing out dentry pointers We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Cc: Greg Kroah-Hartman <[email protected]> Acked-by: "J.

2015-04-23nfs: fix high load average due to callback thread sleepingJeff Layton1-3/+3
Chuck pointed out a problem that crept in with commit 6ffa30d3f734 (nfs: don't call blocking operations while !TASK_RUNNING). Linux counts tasks in uninterruptible sleep against the load average, so this caused the system's load average to be pinned at at least 1 when there was a NFSv4.1+ mount active. Not a huge problem, but it's probably worth fixing before we get too many complaints about it. This patch converts the code back to use TASK_INTERRUPTIBLE sleep, simply has it flush any signals on each loop iteration. In practice no one should really be signalling this thread at all, so I think this is reasonably safe. With this change, there's also no need to game the hung task watchdog so we can also convert the schedule_timeout call back to a normal schedule.

This patch adds a GETATTR to the end of ALLOCATE and DEALLOCATE operations so we can set the updated inode size and change attribute directly.

2015-04-23i2c: Mark adapter devices with pm_runtime_no_callbacksCharles Keepax1-0/+2
Commit 523c5b89640e ("i2c: Remove support for legacy PM") removed the PM ops from the bus type, which causes the pm operations on the s3c2410 adapter device to fail (-ENOSUPP in rpm_callback). The adapter device doesn't get bound to a driver and as such can't have its own pm_runtime callbacks. Previously this was fine as the bus callbacks would have been used, but now this can cause devices which use PM runtime and are attached over I2C to fail to resume. This commit fixes this issue by marking all adapter devices with pm_runtime_no_callbacks, since they can't have any.

2015-04-23tipc: fix node refcount issueErik Hugne1-1/+0
When link statistics is dumped over netlink, we iterate over the list of peer nodes and append each links statistics to the netlink msg. In the case where the dump is resumed after filling up a nlmsg, the node refcnt is decremented without having been incremented previously which may cause the node reference to be freed. When this happens, the following info/stacktrace will be generated, followed by a crash or undefined behavior. We fix this by removing the erroneous call to tipc_node_put inside the loop that iterates over nodes. [ 384.312303] INFO: trying to register non-static key.

2015-04-23tipc: fix topology server broken issueYing Xue1-6/+3
When a new topology server is launched in a new namespace, its listening socket is inserted into the "init ns" namespace's socket hash table rather than the one owned by the new namespace. Although the socket's namespace is forcedly changed to the new namespace later, the socket is still stored in the socket hash table of "init ns" namespace. When a client created in the new namespace connects its own topology server, the connection is failed as its server's socket could not be found from its own namespace's socket table. If __sock_create() instead of original sock_create_kern() is used to create the server's socket through specifying an expected namesapce, the socket will be inserted into the specified namespace's socket table, thereby avoiding to the topology server broken issue.

2015-04-23ibmveth: Fix off-by-one error in ibmveth_change_mtu()David Gibson1-2/+2
AFAIK the PAPR document which defines the virtual device interface used by the ibmveth driver doesn't specify a specific maximum MTU. So, in the ibmveth driver, the maximum allowed MTU is determined by the maximum allocated buffer size of 64k (corresponding to one page in the common case) minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14 bytes of ethernet header, plus 8 bytes for an opaque handle). This suggests a maximum allowable MTU of 65514 bytes, but in fact the driver only permits a maximum MTU of 65513. This is because there is a < instead of an <= in ibmveth_change_mtu(), which only permits an MTU which is strictly smaller than the buffer size, rather than allowing the buffer to be completely filled.

2015-04-23pm: sometimes wake up from suspend to RAM would failAaron Wu1-0/+2
Sometimes it fails to wake up from suspend to RAM, this is because we would flush the data cache by assemble command FLUSHINV before suspend to RAM, and there is a delay between this command execution and cache flush completion. Add a 1uS delay to works around this. Signed-off-by: Aaron Wu <[email protected]>

2015-04-23pwm: Remove __init initializer for pwm_add_table()Shobhit Kumar1-1/+1
For platforms that don't support DT, some early MFD modules can register lookup tables. Remove the __init annotation so that this works. This is similar to gpio_add_lookup_table() which allows late additions.
