2011-03-12ipv4: Create and use route lookup helpers.David S. Miller

2011-03-11RPCRDMA: Fix FRMR registration/invalidate handling.Tom Tucker
When the rpc_memreg_strategy is 5, FRMR are used to map RPC data. This mode uses an FRMR to map the RPC data, then invalidates (i.e. unregisers) the data in xprt_rdma_free. These FRMR are used across connections on the same mount, i.e. if the connection goes away on an idle timeout and reconnects later, the FRMR are not destroyed and recreated. This creates a problem for transport errors because the WR that invalidate an FRMR may be flushed (i.e. fail) leaving the FRMR valid. When the FRMR is later used to map an RPC it will fail, tearing down the transport and starting over. Over time, more and more of the FRMR pool end up in the wrong state resulting in seemingly random disconnects. This fix keeps track of the FRMR state explicitly by setting it's state based on the successful completion of a reg/inv WR. If the FRMR is ever used and found to be in the wrong state, an invalidate WR is prepended, re-syncing the FRMR state and avoiding the connection loss.

2011-03-11RPCRDMA: Fix to XDR page base interpretation in marshalling logic.Tom Tucker
The RPCRDMA marshalling logic assumed that xdr->page_base was an offset into the first page of xdr->page_list. It is in fact an offset into the xdr->page_list itself, that is, it selects the first page in the page_list and the offset into that page. The symptom depended in part on the rpc_memreg_strategy, if it was FRMR, or some other one-shot mapping mode, the connection would get torn down on a base and bounds error. When the badly marshalled RPC was retransmitted it would reconnect, get the error, and tear down the connection again in a loop forever. This resulted in a hung-mount. For the other modes, it would result in silent data corruption. This bug is most easily reproduced by writing more data than the filesystem has space for. This fix corrects the page_base assumption and otherwise simplifies the iov mapping logic. Signed-off-by: Tom Tucker <tom@ogc.us> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2011-03-11mac80211: do not enable ps if 802.1x controlled port is unblockedJason Young
If dynamic_ps is disabled, enabling power save before the 4-way handshake completes may delay the station from being authorized to send/receive traffic, i.e. increase roaming times. It also may result in a failed 4-way handshake depending on the AP's timing requirements and beacon interval, and the station's listen interval. To fix this, prevent power save from being enabled while the station isn't authorized and recalculate power save whenever the station's authorized state changes.

2011-03-10SUNRPC: Close a race in __rpc_wait_for_completion_task()Trond Myklebust
Although they run as rpciod background tasks, under normal operation (i.e. no SIGKILL), functions like nfs_sillyrename(), nfs4_proc_unlck() and nfs4_do_close() want to be fully synchronous. This means that when we exit, we want all references to the rpc_task to be gone, and we want any dentry references etc. held by that task to be released. For this reason these functions call __rpc_wait_for_completion_task(), followed by rpc_put_task() in the expectation that the latter will be releasing the last reference to the rpc_task, and thus ensuring that the callback_ops->rpc_release() has been called synchronously. This patch fixes a race which exists due to the fact that rpciod calls rpc_complete_task() (in order to wake up the callers of __rpc_wait_for_completion_task()) and then subsequently calls rpc_put_task() without ensuring that these two steps are done atomically. In order to avoid adding new spin locks, the patch uses the existing waitqueue spin lock to order the rpc_task reference count releases between the waiting process and rpciod. The common case where nobody is waiting for completion is optimised for by checking if the RPC_TASK_ASYNC flag is cleared and/or if the rpc_task reference count is 1: in those cases we drop trying to grab the spin lock, and immediately free up the rpc_task. Those few processes that need to put the rpc_task from inside an asynchronous context and that do not care about ordering are given a new helper: rpc_put_task_async().

2011-03-09ipv6: Don't create clones of host routes.David S. Miller
Addresses https://bugzilla.kernel.org/show_bug.cgi?id=29252 Addresses https://bugzilla.kernel.org/show_bug.cgi?id=30462 In commit d80bc0fd262ef840ed4e82593ad6416fa1ba3fc4 ("ipv6: Always clone offlink routes.") we forced the kernel to always clone offlink routes. The reason we do that is to make sure we never bind an inetpeer to a prefixed route. The logic turned on here has existed in the tree for many years, but was always off due to a protecting CPP define. So perhaps it's no surprise that there is a logic bug here. The problem is that we canot clone a route that is already a host route (ie. has DST_HOST set). Because if we do, an identical entry already exists in the routing tree and therefore the ip6_rt_ins() call is going to fail. This sets off a series of failures and high cpu usage, because when ip6_rt_ins() fails we loop retrying this operation a few times in order to handle a race between two threads trying to clone and insert the same host route at the same time. Fix this by simply using the route as-is when DST_HOST is set. Reported-by: slash@ac.auone-net.jp Reported-by: Ernst Sjöstrand <ernstp@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-10net: don't allow CAP_NET_ADMIN to load non-netdev kernel modulesVasiliy Kulikov
Since a8f80e8ff94ecba629542d9b4b5f5a8ee3eb565c any process with CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't allow anybody load any module not related to networking. This patch restricts an ability of autoloading modules to netdev modules with explicit aliases. This fixes CVE-2011-1019. Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior of loading netdev modules by name (without any prefix) for processes with CAP_SYS_MODULE to maintain the compatibility with network scripts that use autoloading netdev modules by aliases like "eth0", "wlan0".

2011-03-09ipv4: Fix erroneous uses of ifa_address.David S. Miller
In usual cases ifa_address == ifa_local, but in the case where SIOCSIFDSTADDR sets the destination address on a point-to-point link, ifa_address gets set to that destination address. Therefore we should use ifa_local when we want the local interface address. There were two cases where the selection was done incorrectly: 1) When devinet_ioctl() does matching, it checks ifa_address even though gifconf correct reported ifa_local to the user 2) IN_DEV_ARP_NOTIFY handling sends a gratuitous ARP using ifa_address instead of ifa_local.

2011-03-09net/wireless: add COUNTRY to to regulatory device ueventScott James Remnant
Regulatory devices issue change uevents to inform userspace of a need to call the crda tool; however these can often be sent before udevd is running, and were not previously included in the results of udevadm trigger (which requests a new change event using the /uevent attribute of the sysfs object). Add a uevent function to the device type which includes the COUNTRY information from the last request if it has yet to be processed, the case of multiple requests is already handled in the code by checking whether an unprocessed one is queued in the same manner and refusing to queue a new one. The existing udev rule continues to work as before.

2011-03-08svcrpc: fix rare race on unix_domain creationJ. Bruce Fields
Note that "new" here is not yet fully initialized; auth_domain_put should be called only on auth_domains that have actually been added to the hash. Before this fix, two attempts to add the same domain at once could cause the hlist_del in auth_domain_put to fail. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2011-03-07ipv4: Cache source address in nexthop entries.David S. Miller
When doing output route lookups, we have to select the source address if the user has not specified an explicit one. First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().
