2012-07-18libceph: fix messenger retrySage Weil1-10/+2
In ancient times, the messenger could both initiate and accept connections. An artifact if that was data structures to store/process an incoming ceph_msg_connect request and send an outgoing ceph_msg_connect_reply. Sadly, the negotiation code was referencing those structures and ignoring important information (like the peer's connect_seq) from the correct ones. Among other things, this fixes tight reconnect loops where the server sends RETRY_SESSION and we (the client) retries with the same connect_seq as last time. This bug pretty easily triggered by injecting socket failures on the MDS and running some fs workload like workunits/direct_io/test_sync_io. Signed-off-by: Sage Weil <sage@inktank.com>
2012-07-18pstore/ram: Make tracing log versionedAnton Vorontsov1-1/+1
Decoding the binary trace w/ a different kernel might be troublesome since we convert addresses to symbols. For kernels with minimal changes, the mappings would probably match, but it's not guaranteed at all. (But still we could convert the addresses by hand, since we do print raw addresses.) If we use modules, the symbols could be loaded at different addresses from the previously booted kernel, and so this would also fail, but there's nothing we can do about it. Also, the binary data format that pstore/ram is using in its ringbuffer may change between the kernels, so here we too must ensure that we're running the same kernel. So, there are two questions really: 1. How to compute the unique kernel tag; 2. Where to store it. In this patch we're using LINUX_VERSION_CODE, just as hibernation (suspend-to-disk) does. This way we are protecting from the kernel version mismatch, making sure that we're running the same kernel version and patch level. We could use CRC of a symbol table (as suggested by Tony Luck), but for now let's not be that strict. And as for storing, we are using a small trick here. Instead of allocating a dedicated buffer for the tag (i.e. another prz), or hacking ram_core routines to "reserve" some control data in the buffer, we are just encoding the tag into the buffer signature (and XOR'ing it with the actual signature value, so that buffers not needing a tag can just pass zero, which will result into the plain old PRZ signature).

2012-07-17workqueue: perform cpu down operations from low priority cpu_notifier()Tejun Heo1-2/+3
Currently, all workqueue cpu hotplug operations run off CPU_PRI_WORKQUEUE which is higher than normal notifiers. This is to ensure that workqueue is up and running while bringing up a CPU before other notifiers try to use workqueue on the CPU. Per-cpu workqueues are supposed to remain working and bound to the CPU for normal CPU_DOWN_PREPARE notifiers. This holds mostly true even with workqueue offlining running with higher priority because workqueue CPU_DOWN_PREPARE only creates a bound trustee thread which runs the per-cpu workqueue without concurrency management without explicitly detaching the existing workers. However, if the trustee needs to create new workers, it creates unbound workers which may wander off to other CPUs while CPU_DOWN_PREPARE notifiers are in progress. Furthermore, if the CPU down is cancelled, the per-CPU workqueue may end up with workers which aren't bound to the CPU. While reliably reproducible with a convoluted artificial test-case involving scheduling and flushing CPU burning work items from CPU down notifiers, this isn't very likely to happen in the wild, and, even when it happens, the effects are likely to be hidden by the following successful CPU down. Fix it by using different priorities for up and down notifiers - high priority for up operations and low priority for down operations. Workqueue cpu hotplug operations will soon go through further cleanup. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: stable@vger.kernel.org Acked-by: "Rafael J. Wysocki" <rjw@sisk.pl>
2012-07-17PM: Rename CAP_EPOLLWAKEUP to CAP_BLOCK_SUSPENDMichael Kerrisk2-4/+4
As discussed in http://thread.gmane.org/gmane.linux.kernel/1249726/focus=1288990, the capability introduced in 4d7e30d98939a0340022ccd49325a3d70f7e0238 to govern EPOLLWAKEUP seems misnamed: this capability is about governing the ability to suspend the system, not using a particular API flag (EPOLLWAKEUP). We should make the name of the capability more general to encourage reuse in related cases. (Whether or not this capability should also be used to govern the use of /sys/power/wake_lock is a question that needs to be separately resolved.) This patch renames the capability to CAP_BLOCK_SUSPEND. In order to ensure that the old capability name doesn't make it out into the wild, could you please apply and push up the tree to ensure that it is incorporated for the 3.5 release.

2012-07-17GPIO: PCA953X: Increase size of invert variable to support 24 bitChandrabhanu Mahapatra1-1/+1
TCA6424 is a low voltage 24 bit I2C and SMBus I/O expander of pca953x family similar to its 16 bit predecessor TCA6416. It comes with three 8-bit active Input, Output, Polarity Inversion and Configuration registers each. The polarity of Input ports can be reversed by setting the appropiate bit in Polarity Inversion registers. The variables corresponding to Input, Output and Configuration registers have already been updated to support 24 bit values. This patch thus updates the invert variable of PCA953X platform data to support 24 bit.

2012-07-16NFS: Treat NFS4ERR_CLID_INUSE as a fatal errorChuck Lever1-2/+1
For NFSv4 minor version 0, currently the cl_id_uniquifier allows the Linux client to generate a unique nfs_client_id4 string whenever a server replies with NFS4ERR_CLID_INUSE. This implementation seems to be based on a flawed reading of RFC 3530. NFS4ERR_CLID_INUSE actually means that the client has presented this nfs_client_id4 string with a different principal at some time in the past, and that lease is still in use on the server. For a Linux client this might be rather difficult to achieve: the authentication flavor is named right in the nfs_client_id4.id string. If we change flavors, we change strings automatically. So, practically speaking, NFS4ERR_CLID_INUSE means there is some other client using our string. There is not much that can be done to recover automatically. Let's make it a permanent error. Remove the recovery logic in nfs4_proc_setclientid(), and remove the cl_id_uniquifier field from the nfs_client data structure. And, remove the authentication flavor from the nfs_client_id4 string. Keeping the authentication flavor in the nfs_client_id4.id string means that we could have a separate lease for each authentication flavor used by mounts on the client. But we want just one lease for all the mounts on this client. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-07-16SUNRPC: Add rpcauth_list_flavors()Chuck Lever2-1/+4
The gss_mech_list_pseudoflavors() function provides a list of currently registered GSS pseudoflavors. This list does not include any non-GSS flavors that have been registered with the RPC client. nfs4_find_root_sec() currently adds these extra flavors by hand. Instead, nfs4_find_root_sec() should be looking at the set of flavors that have been explicitly registered via rpcauth_register(). And, other areas of code will soon need the same kind of list that contains all flavors the kernel currently knows about (see below). Rather than cloning the open-coded logic in nfs4_find_root_sec() to those new places, introduce a generic RPC function that generates a full list of registered auth flavors and pseudoflavors. A new rpc_authops method is added that lists a flavor's pseudoflavors, if it has any. I encountered an interesting module loader loop when I tried to get the RPC client to invoke gss_mech_list_pseudoflavors() by name. This patch is a pre-requisite for server trunking discovery, and a pre-requisite for fixing up the in-kernel mount client to do better automatic security flavor selection.
