2016-06-11Merge tag 'scsi-fixes' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi Pull SCSI fixes from James Bottomley: "Two current fixes: - one affects Qemu CD ROM emulation, which stopped working after the updates in SCSI to require VPD pages from all conformant devices. Fix temporarily by blacklisting Qemu (we can relax later when they come into compliance). - The other is a fix to the optimal transfer size. We set up a minefield for ourselves by being confused about whether the limits are in bytes or sectors (SCSI optimal is in blocks and the queue parameter is in bytes). This tries to fix the problem (wrong setting for queue limits max_sectors) and make the problem more obvious by introducing a wrapper function" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: sd: Fix rw_max for devices that report an optimal xfer size scsi: Add QEMU CD-ROM to VPD Inquiry Blacklist

2016-06-11staging: iio: fix ad7606_spi regressionArnd Bergmann
As pointed out by Geert Uytterhoeven, the patch was incorrect and breaks the driver, which was fortunately pointed out by this gcc warning: drivers/staging/iio/adc/ad7606_spi.c: In function ‘ad7606_spi_read_block’: drivers/staging/iio/adc/ad7606_spi.c:34: warning: ‘data’ is used uninitialized in this function The effect of the patch is that the data is copied into a random memory location (from the uninitialized pointer) instead of being byteswapped in place. This adds the initialization for the 'data' variable back to restore the original behavior.

John Crispin says: ==================== net: mediatek: various small fixes This series contains various small fixes that we stumbled across while doing thorough testing and code level reviewing of the driver. Changes in V2: * drop the DQL patch from the list until a better solution is found ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: remove superfluous queue wake up callJohn Crispin
The code checks if the queue should be stopped because we are below the threshold of free descriptors only to check if it should be started again. If we do end up in a state where we are at the threshold limit, it makes more sense to just stop the queue and wait for the next IRQ to trigger the TX housekeeping again. There is no rush in enqueuing the next packet, it needs to wait for all the others in the queue to be dispatched first anyway. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: only wake the queue if it is stoppedJohn Crispin
The current code unconditionally wakes up the queue at the end of each tx_poll action. Change the code to only wake up the queues if any of them have actually been stopped before. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: fix off by one in the TX ring allocationJohn Crispin
The TX ring setup has an off by one error causing it to not utilise all descriptors. This has the side effect that we need to reset the next pointer at runtime to make it work. Fix the off by one and remove the code fixing the ring at runtime. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: increase watchdog_timeoJohn Crispin
During stress testing, after reducing the threshold value, we have seen TX timeouts that were caused by the watchdog_timeo value being too low. Increase the value to 5 * HZ which is a value commonly used by many other drivers. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: fix threshold valueJohn Crispin
The logic to calculate the threshold value for stopping the TX queue is bad. Currently it will always use 1/2 of the rings size, which is way too much. Set the threshold to MAX_SKB_FRAGS. This makes sure that the queue is stopped when there is not enough room to accept an additional segment.  Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: disable all interrupts during probeJohn Crispin
The current code only disables those IRQs that we will later use. To ensure that we have a predefined state, we really want to disable all IRQs. Change the code to disable all IRQs to achieve this. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: add next data pointer coherency protectionJohn Crispin
The QDMA engine can fail to update the register pointing to the next TX descriptor if this bit does not get set in the QDMA configuration register. Not setting this bit can result in invalid values inside the TX rings registers which will causes TX stalls. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: dropped rx packets are not being counted properlyJohn Crispin

2016-06-10net: mediatek: invalid buffer lookup in mtk_tx_map()John Crispin
The lookup of the tx_buffer in the error path inside mtk_tx_map() uses the wrong descriptor pointer. This looks like a copy & paste error. Change the code to use the correct pointer. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-10net: mediatek: fix missing free of scratch memoryJohn Crispin
Scratch memory gets allocated in mtk_init_fq_dma() but the corresponding code to free it is missing inside mtk_dma_free() causing a memory leak. With this patch applied, we can run ifconfig up/down several thousand times without any problems. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-06-10bridge: Fix incorrect re-injection of STP packetsIdo Schimmel
Commit 8626c56c8279 ("bridge: fix potential use-after-free when hook returns QUEUE or STOLEN verdict") fixed incorrect usage of NF_HOOK's return value by consuming packets in okfn via br_pass_frame_up(). However, this function re-injects packets to the Rx path with skb->dev set to the bridge device, which breaks kernel's STP, as all STP packets appear to originate from the bridge device itself. Instead, if STP is enabled and bridge isn't a 802.1ad bridge, then learn packet's SMAC and inject it back to the Rx path for further processing by the packet handlers. The patch also makes netfilter's behavior consistent with regards to packets destined to the Bridge Group Address, as no hook registered at LOCAL_IN will ever be called, regardless if STP is enabled or not.

2016-06-10net: phy: smsc: reintroduced unconditional soft resetManfred Schlaegl
We detected some problems using the smsc lan8720a in combination with i.MX28 and tracked this down to commit 21009686662f ("net: phy: smsc: move smsc_phy_config_init reset part in a soft_reset function") With 2100968666 the generic soft reset is replaced by a specific function which handles power down state correctly. But additionally the soft reset itself got conditional and is therefore also only performed if the phy is in power down state. This patch keeps the conditional wake up from power down, but re-introduces the unconditional soft reset using the generic soft reset function. It was tested on linux-4.1.25 and linux-4.7.0-rc2.

2016-06-10sched: panic on corrupted stack endJann Horn
Until now, hitting this BUG_ON caused a recursive oops (because oops handling involves do_exit(), which calls into the scheduler, which in turn raises an oops), which caused stuff below the stack to be overwritten until a panic happened (e.g. via an oops in interrupt context, caused by the overwritten CPU index in the thread_info).

This prevents stacking filesystems (ecryptfs and overlayfs) from using procfs as lower filesystem. There is too much magic going on inside procfs, and there is no good reason to stack stuff on top of procfs. (For example, procfs does access checks in VFS open handlers, and ecryptfs by design calls open handlers from a kernel thread that doesn't drop privileges or so.)

Unfortunately, branch reordering is just as bad from d_walk() POV and we have two places that do it without touching rename_lock - one in handling of cursors (for ramfs-style directories) and another in autofs. autofs one is a separate story; this commit deals with the cursors. * mark cursor dentries explicitly at allocation time * make __dentry_kill() leave ->d_child.next pointing to the next non-cursor sibling, making sure that it won't be moved around unnoticed before the parent is relocked on ascend-to-parent path in d_walk(). * make d_walk() skip cursors explicitly; strictly speaking it's not necessary (all callbacks we pass to d_walk() are no-ops on cursors), but it makes analysis easier.
