2016-08-08printk: Remove unnecessary #ifdef CONFIG_PRINTKAndreas Ziegler
In commit 874f9c7da9a4 ("printk: create pr_<level> functions"), new pr_level defines were added to printk.c. These new defines are guarded by an #ifdef CONFIG_PRINTK - however, there is already a surrounding #ifdef CONFIG_PRINTK starting a lot earlier in line 249 which means the newly introduced #ifdef is unnecessary. Let's remove it to avoid confusion.

2016-08-08libnvdimm, nd_blk: mask off reserved status bitsRoss Zwisler
The "NVDIMM Block Window Driver Writer's Guide": http://pmem.io/documents/NVDIMM_DriverWritersGuide-July-2016.pdf ...defines the layout of the block window status register. For the July 2016 version of the spec linked to above, this happens in Figure 4 on page 26. The only bits defined in this spec are bits 31, 5, 4, 2, 1 and 0. The rest of the bits in the status register are reserved, and there is a warning following the diagram that says: Note: The driver cannot assume the value of the RESERVED bits in the status register are zero. These reserved bits need to be masked off, and the driver must avoid checking the state of those bits. This change ensures that for hardware implementations that set these reserved bits in the status register, the driver won't incorrectly fail the block I/Os.

2016-08-08crypto: caam - defer aead_set_sh_desc in case of zero authsizeHoria Geantă
To be able to generate shared descriptors for AEAD, the authentication size needs to be known. However, there is no imposed order of calling .setkey, .setauthsize callbacks. Thus, in case authentication size is not known at .setkey time, defer it until .setauthsize is called. The authsize != 0 check was incorrectly removed when converting the driver to the new AEAD interface.

2016-08-08crypto: caam - fix echainiv(authenc) encrypt shared descriptorHoria Geantă
There are a few things missed by the conversion to the new AEAD interface: 1 - echainiv(authenc) encrypt shared descriptor The shared descriptor is incorrect: due to the order of operations, at some point in time MATH3 register is being overwritten. 2 - buffer used for echainiv(authenc) encrypt shared descriptor Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually exclusive and thus use the same buffer in context state: sh_desc_enc. However, there's one place missed by s/sh_desc_givenc/sh_desc_enc, leading to errors when echainiv(authenc(...)) algorithms are used: DECO: desc idx 14: Header Error. Invalid length or parity, or certain other problems. While here, also fix a typo: dma_mapping_error() is checking for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

2016-08-08s390/qdio: avoid reschedule of outbound tasklet once killedUrsula Braun
During qdio_shutdown the queue tasklets are killed for all inbound and outbound queues. The queue structures might be freed after qdio_shutdown. Thus it must be guaranteed that these queue tasklets are not rescheduled after that. In addition the outbound queue timers are deleted and it must be guaranteed that these timers are not restarted after qdio_shutdown processing. Timer deletion should make use of del_timer_sync() to make sure qdio_outbound_timer() is finished on other CPUs as well. Queue tasklets should be scheduled in state QDIO_IRQ_STATE_ACTIVE only.

if two string compare equal the clcle instruction will update the string addresses to point _after_ the string. This might already be on a different page, so we should not use these pointer to calculate the difference as in that case the calculation of the difference can cause oopses. The return value of memcmp does not need the difference, we can just reuse the condition code and return for CC=1 (All bytes compared, first operand low) -1 and for CC=2 (All bytes compared, first operand high) +1 strstr also does not need the diff. While fixing this, make the common function clcle "correct on its own" by using l1 instead of l2 for the first length. strstr will call this with l2 for both strings.

2016-08-08ovl: don't copy up opaquenessMiklos Szeredi
When a copy up of a directory occurs which has the opaque xattr set, the xattr remains in the upper directory. The immediate behavior with overlayfs is that the upper directory is not treated as opaque, however after a remount the opaque flag is used and upper directory is treated as opaque. This causes files created in the lower layer to be hidden when using multiple lower directories. Fix by not copying up the opaque flag. To reproduce: ----8<---------8<---------8<---------8<---------8<---------8<---- mkdir -p l/d/s u v w mnt mount -t overlay overlay -olowerdir=l,upperdir=u,workdir=w mnt rm -rf mnt/d/ mkdir -p mnt/d/n umount mnt mount -t overlay overlay -olowerdir=u:l,upperdir=v,workdir=w mnt touch mnt/d/foo umount mnt mount -t overlay overlay -olowerdir=u:l,upperdir=v,workdir=w mnt ls mnt/d ----8<---------8<---------8<---------8<---------8<---------8<---- output should be: "foo n" Reported-by: Derek McGowan <dmcg@drizz.net> Link: https://bugzilla.kernel.org/show_bug.cgi?id=151291 Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Cc: <stable@vger.kernel.org>
2016-08-08USB: serial: fix memleak in driver-registration error pathAlexey Klimov
udriver struct allocated by kzalloc() will not be freed if usb_register() and next calls fail. This patch fixes this by adding one more step with kfree(udriver) in error path.

2016-08-08ARM: dts: armada-388-clearfog: number LAN ports properlyRussell King
Currently, the ports as seen from the rear number as: eth0 sfp lan5 lan4 lan3 lan2 lan1 lan6 which is illogical - this came about because the rev 2.0 boards have the LEDs on the front for the DSA switch (lan5-1) reversed. Rev 2.1 boards fixed the LED issue, and the Clearfog case numbers the lan ports increasing from left to right. Maintaining this illogical numbering causes confusion, with reports that "my link isn't coming up" and "my connection negotiates 10base-Half" both of which are due to people thinking that the port next to the SFP is lan1. Fix this by renumbering the ports to match people's expectations.

Do not drop packet when CSeq is 0 as 0 is also a valid value for CSeq. simple_strtoul() will return 0 either when all digits are 0 or if there are no digits at all. Therefore when simple_strtoul() returns 0 we check if first character is digit 0 or not.

If we find a matching element that is inactive with no descendants, we jump to the found label, then crash because of nul-dereference on the left branch. Fix this by checking that the element is active and not an interval end and skipping the logic that only applies to the tree iteration.

2016-08-08memory: omap-gpmc: allow probe of child nodes to failJohan Hovold
A recent commit (inadvertently?) changed how failed probe of a gpmc child node was handled. Instead of proceeding with setting up any other children as before, a single error now aborts the whole process. This change broke networking on some Overo boards due to probe failing for an unrelated nand node. This second issue should obviously be fixed, but let's restore the old behaviour of allowing child-node probe to fail to avoid further similar breakage on other systems.

2016-08-08dmaengine: usb-dmac: check CHCR.DE bit in usb_dmac_isr_channel()Yoshihiro Shimoda
The USB-DMAC's interruption happens even if the CHCR.DE is not set to 1 because CHCR.NULLE is set to 1. So, this driver should call usb_dmac_isr_transfer_end() if the DE bit is set to 1 only. Otherwise, the desc is possible to be NULL in the usb_dmac_isr_transfer_end().

Commit 96d1327ac2e3 ("netfilter: h323: Use mod_timer instead of set_expect_timeout") just simplify the source codes if (!del_timer(&exp->timeout)) return 0; add_timer(&exp->timeout); to mod_timer(&exp->timeout, jiffies + info->timeout * HZ); This is not correct, and introduce a race codition: CPU0 CPU1 - timer expire process_rcf expectation_timed_out lock(exp_lock) - find_exp waiting exp_lock... re-activate timer!! waiting exp_lock... unlock(exp_lock) lock(exp_lock) - unlink expect - free(expect) - unlock(exp_lock) So when the timer expires again, we will access the memory that was already freed. Replace mod_timer with mod_timer_pending here to fix this problem.

2016-08-08Revert "wext: Fix 32 bit iwpriv compatibility issue with 64 bit Kernel"Johannes Berg
This reverts commit 3d5fdff46c4b2b9534fa2f9fc78e90a48e0ff724. Ben Hutchings pointed out that the commit isn't safe since it assumes that the structure used by the driver is iw_point, when in fact there's no way to know about that. Fortunately, the only driver in the tree that ever runs this code path is the wilc1000 staging driver, so it doesn't really matter. Clearly I should have investigated this better before applying, sorry.
