2011-02-11pci: use security_capable() when checking capablities during config space readChris Wright1-1/+2
Eric Paris noted that commit de139a3 ("pci: check caps from sysfs file open to read device dependent config space") caused the capability check to bypass security modules and potentially auditing. Rectify this by calling security_capable() when checking the open file's capabilities for config space reads.

2011-02-11cifs: don't always drop malformed replies on the floor (try #3)Jeff Layton3-7/+28
Slight revision to this patch...use min_t() instead of conditional assignment. Also, remove the FIXME comment and replace it with the explanation that Steve gave earlier. After receiving a packet, we currently check the header. If it's no good, then we toss it out and continue the loop, leaving the caller waiting on that response. In cases where the packet has length inconsistencies, but the MID is valid, this leads to unneeded delays. That's especially problematic now that the client waits indefinitely for responses. Instead, don't immediately discard the packet if checkSMB fails. Try to find a matching mid_q_entry, mark it as having a malformed response and issue the callback.

2011-02-11tpm_tis: Use timeouts returned from TPMStefan Berger3-3/+21
The current TPM TIS driver in git discards the timeout values returned from the TPM. The check of the response packet needs to consider that the return_code field is 0 on success and the size of the expected packet is equivalent to the header size + u32 length indicator for the TPM_GetCapability() result + 3 timeout indicators of type u32. I am also adding a sysfs entry 'timeouts' showing the timeouts that are being used.

2011-02-10char/ipmi: fix OOPS caused by pnp_unregister_driver on unregistered driverCorey Minyard1-10/+2
This patch fixes an OOPS triggered when calling modprobe ipmi_si a second time after the first modprobe returned without finding any ipmi devices. This can happen if you reload the module after having the first module load fail. The driver was not deregistering from PNP in that case. Peter Huewe originally reported this patch and supplied a fix, I have a different patch based on Linus' suggestion that cleans things up a bit more.

2011-02-10cap_syslog: accept CAP_SYS_ADMIN for nowLinus Torvalds1-19/+35
In commit ce6ada35bdf7 ("security: Define CAP_SYSLOG") Serge Hallyn introduced CAP_SYSLOG, but broke backwards compatibility by no longer accepting CAP_SYS_ADMIN as an override (it would cause a warning and then reject the operation). Re-instate CAP_SYS_ADMIN - but keeping the warning - as an acceptable capability until any legacy applications have been updated. There are apparently applications out there that drop all capabilities except for CAP_SYS_ADMIN in order to access the syslog.

2011-02-09KVM: SVM: Make sure KERNEL_GS_BASE is valid when loading gs_indexJoerg Roedel1-1/+1
The gs_index loading code uses the swapgs instruction to switch to the user gs_base temporarily. This is unsave in an lightweight exit-path in KVM on AMD because the KERNEL_GS_BASE MSR is switches lazily. An NMI happening in the critical path of load_gs_index may use the wrong GS_BASE value then leading to unpredictable behavior, e.g. a triple-fault.

2011-02-09cfq-iosched: Don't wait if queue already has requests.Justin TerAvest1-0/+4
Commit 7667aa0630407bc07dc38dcc79d29cc0a65553c1 added logic to wait for the last queue of the group to become busy (have at least one request), so that the group does not lose out for not being continuously backlogged. The commit did not check for the condition that the last queue already has some requests. As a result, if the queue already has requests, wait_busy is set. Later on, cfq_select_queue() checks the flag, and decides that since the queue has a request now and wait_busy is set, the queue is expired. This results in early expiration of the queue. This patch fixes the problem by adding a check to see if queue already has requests. If it does, wait_busy is not set. As a result, time slices do not expire early. The queues with more than one request are usually buffered writers. Testing shows improvement in isolation between buffered writers.

2011-02-08net: Fix lockdep regression caused by initializing netdev queues too early.David S. Miller1-11/+16
In commit aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress queue") we moved the allocation and lock initialization of the queues into alloc_netdev_mq() since register_netdevice() is way too late. The problem is that dev->type is not setup until the setup() callback is invoked by alloc_netdev_mq(), and the dev->type is what determines the lockdep class to use for the locks in the queues. Fix this by doing the queue allocation after the setup() callback runs. This is safe because the setup() callback is not allowed to make any state changes that need to be undone on error (memory allocations, etc.). It may, however, make state changes that are undone by free_netdev() (such as netif_napi_add(), which is done by the ipoib driver's setup routine). The previous code also leaked a reference to the &init_net namespace object on RX/TX queue allocation failures. Signed-off-by: David S. Miller <[email protected]>

rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(), cannot make state changes which need to be undone on failure. There is no cleanup mechanism available at this point. So we have to add the caif private instance to the global list once we are sure that register_netdev() has succedded in ->newlink(). Otherwise, if register_netdev() fails, the caller will invoke free_netdev() and we will have a reference to freed up memory on the chnl_net_list. Signed-off-by: David S. Miller <[email protected]>
