* | Add suspend-related notifications for CPU hotplugRafael J. Wysocki2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

* | knfsd: simplify a 'while' condition in svcsock.cNeilBrown2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This while loop has an overly complex condition, which performs a couple of assignments. This hurts readability. We don't really need a loop at all. We can just return -EAGAIN and (providing we set SK_DATA), the function will be called again. So discard the loop, make the complex conditional become a few clear function calls, and hopefully improve readability.

* | knfsd: fix resource leak resulting in module refcount leak for ↵Frank Filz2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rpcsec_gss_krb5.ko I have been investigating a module reference count leak on the server for rpcsec_gss_krb5.ko. It turns out the problem is a reference count leak for the security context in net/sunrpc/auth_gss/svcauth_gss.c. The problem is that gss_write_init_verf() calls gss_svc_searchbyctx() which does a rsc_lookup() but never releases the reference to the context. There is another issue that rpc.svcgssd sets an "end of time" expiration for the context By adding a cache_put() call in gss_svc_searchbyctx(), and setting an expiration timeout in the downcall, cache_clean() does clean up the context and the module reference count now goes to zero after unmount. I also verified that if the context expires and then the client makes a new request, a new context is established. Here is the patch to fix the kernel, I will start a separate thread to discuss what expiration time should be set by rpc.svcgssd. Acked-by: "J.

* | RPC: add wrapper for svc_reserve to account for checksumJeff Layton2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the kernel calls svc_reserve to downsize the expected size of an RPC reply, it fails to account for the possibility of a checksum at the end of the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O then you'll generally see messages similar to this in the server's ring buffer: RPC request reserved 164 but used 208 While I was never able to verify it, I suspect that this problem is also the root cause of some oopses I've seen under these conditions: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726 This is probably also a problem for other sec= types and for NFSv4. The large reserved size for NFSv4 compound packets seems to generally paper over the problem, however. This patch adds a wrapper for svc_reserve that accounts for the possibility of a checksum. It also fixes up the appropriate callers of svc_reserve to call the wrapper. For now, it just uses a hardcoded value that I determined via testing. That value may need to be revised upward as things change, or we may want to eventually add a new auth_op that attempts to calculate this somehow. Unfortunately, there doesn't seem to be a good way to reliably determine the expected checksum length prior to actually calculating it, particularly with schemes like spkm3.

* VFS: delay the dentry name generation on sockets and pipesEric Dumazet2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Introduces a new method in 'struct dentry_operations'. This method called d_dname() might be called from d_path() to build a pathname for special filesystems. It is called without locks. Future patches (if we succeed in having one common dentry for all pipes/sockets) may need to change prototype of this method, but we now use : char *d_dname(struct dentry *dentry, char *buffer, int buflen); 2) Adds a dynamic_dname() helper function that eases d_dname() implementations 3) Defines d_dname method for sockets : No more sprintf() at socket creation. This is delayed up to the moment someone does an access to /proc/pid/fd/... 4) Defines d_dname method for pipes : No more sprintf() at pipe creation. This is delayed up to the moment someone does an access to /proc/pid/fd/...

If the optlen parameter is 0, no data will be copied by copy_from_user(), but the uninitialized stack buffer will be read and stored later. A call to getsockopt() can now retrieve the leaked information. To fix this problem the stack buffer given to copy_from_user() must be initialized with the current settings.

It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a replacement for the in-kernel portmapper client that supports all 3 versions of the rpcbind protocol. This code is not used yet. Original code by Groupe Bull updated for the latest kernel, with multiple bug fixes. Note that rpcb_clnt.c does not yet support registering via versions 3 and 4 of the rpcbind protocol. That is planned for a later patch.

| * | SUNRPC: Eliminate side effects from rpc_mallocChuck Lever2007-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rpc_malloc sets req->rq_buffer internally. Make this a more generic interface: return a pointer to the new buffer (or NULL) and make the caller set req->rq_buffer and req->rq_bufsize. This looks much more like kmalloc and eliminates the side effects. To fix a potential deadlock, this patch also replaces GFP_NOFS with GFP_NOWAIT in rpc_malloc. This prevents async RPCs from sleeping outside the RPC's task scheduler while allocating their buffer.

| * | SUNRPC: RPC buffer size estimates are too largeChuck Lever2007-05-01
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPC buffer size estimation logic in net/sunrpc/clnt.c always significantly overestimates the requirements for the buffer size. A little instrumentation demonstrated that in fact rpc_malloc was never allocating the buffer from the mempool, but almost always called kmalloc. To compute the size of the RPC buffer more precisely, split p_bufsiz into two fields; one for the argument size, and one for the result size. Then, compute the sum of the exact call and reply header sizes, and split the RPC buffer precisely between the two. That should keep almost all RPC buffers within the 2KiB buffer mempool limit. And, we can finally be rid of RPC_SLACK_SPACE! Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* | [SCTP]: Set assoc_id correctly during INIT collision.Vlad Yasevich2007-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the INIT/COOKIE-ACK collision cases, it's possible to get into a situation where the association id is not yet set at the time of the user event generation. As a result, user events have an association id set to 0 which will confuse applications. This happens if we hit case B of duplicate cookie processing. In the particular example found and provided by Oscar Isaula <Oscar.Isaula@motorola.com>, flow looks like this: A B ---- INIT-------> (lost) <---------INIT------ ---- INIT-ACK---> <------ Cookie ECHO When the Cookie Echo is received, we end up trying to update the association that was created on A as a result of the (lost) INIT, but that association doesn't have the ID set yet.
