2014-04-11net: Fix use after free by removing length arg from sk_data_ready callbacks.David S. Miller
Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect. Based upon a patch by Eric Dumazet and his suggestion to audit this issue tree-wide. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-04-11Drivers: net: hyperv: Address UDP checksum issuesKY Srinivasan
ws2008r2 does not support UDP checksum offload. Thus, we cannnot turn on UDP offload in the host. Also, on ws2012 and ws2012 r2, there appear to be an issue with UDP checksum offload. Fix this issue by computing the UDP checksum in the Hyper-V driver. Based on Dave Miller's comments, in this version, I have COWed the skb before modifying the UDP header (the checksum field).

2014-04-10scsi: async sd resumeDan Williams
async_schedule() sd resume work to allow disks and other devices to resume in parallel. This moves the entirety of scsi_device resume to an async context to ensure that scsi_device_resume() remains ordered with respect to the completion of the start/stop command. For the duration of the resume, new command submissions (that do not originate from the scsi-core) will be deferred (BLKPREP_DEFER). It adds a new ASYNC_DOMAIN_EXCLUSIVE(scsi_sd_pm_domain) as a container of these operations. Like scsi_sd_probe_domain it is flushed at sd_remove() time to ensure async ops do not continue past the end-of-life of the sdev. The implementation explicitly refrains from reusing scsi_sd_probe_domain directly for this purpose as it is flushed at the end of dpm_resume(), potentially defeating some of the benefit. Given sdevs are quiesced it is permissible for these resume operations to bleed past the async_synchronize_full() calls made by the driver core. We defer the resolution of which pm callback to call until scsi_dev_type_{suspend|resume} time and guarantee that the callback parameter is never NULL. With this in place the type of resume operation is encoded in the async function identifier. There is a concern that async resume could trigger PSU overload. In the enterprise, storage enclosures enforce staggered spin-up regardless of what the kernel does making async scanning safe by default. Outside of that context a user can disable asynchronous scanning via a kernel command line or CONFIG_SCSI_SCAN_ASYNC. Honor that setting when deciding whether to do resume asynchronously.

2014-04-10NVMe: Retry failed commands with non-fatal errorsKeith Busch
For commands returned with failed status, queue these for resubmission and continue retrying them until success or for a limited amount of time. The final timeout was arbitrarily chosen so requests can't be retried indefinitely. Since these are requeued on the nvmeq that submitted the command, the callbacks have to take an nvmeq instead of an nvme_dev as a parameter so that we can use the locked queue to append the iod to retry later. The nvme_iod conviently can be used to track how long we've been trying to successfully complete an iod request. The nvme_iod also provides the nvme prp dma mappings, so I had to move a few things around so we can keep those mappings.

2014-04-10NVMe: per-cpu io queuesKeith Busch
The device's IO queues are associated with CPUs, so we can use a per-cpu variable to map the a qid to a cpu. This provides a convienient way to optimally assign queues to multiple cpus when the device supports fewer queues than the host has cpus. The previous implementation may have assigned these poorly in these situations. This patch addresses this by sharing queues among cpus that are "close" together and should have a lower lock contention penalty.

2014-04-10efi: Pass correct file handle to efi_file_{read,close}Matt Fleming
We're currently passing the file handle for the root file system to efi_file_read() and efi_file_close(), instead of the file handle for the file we wish to read/close. While this has worked up until now, it seems that it has only been by pure luck. Olivier explains, "The issue is the UEFI Fat driver might return the same function for 'fh->read()' and 'h->read()'. While in our case it does not work with a different implementation of EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. In our case, we return a different pointer when reading a directory and reading a file." Fixing this actually clears up the two functions because we can drop one of the arguments, and instead only pass a file 'handle' argument.

2014-04-09ath9k: fix a scheduling while atomic bug in CSA handlingFelix Fietkau
Commit "ath9k: prepare for multi-interface CSA support" added a call to ieee80211_iterate_active_interfaces in atomic context (beacon tasklet), which is crashing. Use ieee80211_iterate_active_interfaces_atomic instead. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-04-09ath9k_hw: reduce ANI firstep range for older chipsFelix Fietkau
Use 0-8 instead of 0-16, which is closer to the old implementation. Also drop the overwrite of the firstep_low parameter to improve stability. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-04-09ath9k: Enable DFS only when ATH9K_DFS_CERTIFIEDJanusz Dziedzic
Add DFS interface combination only when CONFIG_ATH9K_DFS_CERTIFIED is set. In other case user can run CAC/beaconing without proper handling of pulse events (without radar detection activated).

2014-04-09rtlwifi: btcoexist: remove undefined Kconfig macrosPaul Bolle
There are references to four undefined Kconfig macros in the code. Commit 8542373dccd2 ("Staging: rtl8812ae: remove undefined Kconfig macros") removed identical references from that staging driver, but they resurfaced in rtlwifi. Remove these again as the checks for them still will always evaluate to false. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W. Linville <linville@tuxdriver.com>
