commit 9493c242 upstream. Remove 2 redundant extern inline functions: qla8044_set_qsnt_ready() and qla8044_need_reset_handler(). At present, within upstream next kernel source code, they are only used within "drivers/scsi/qla2xxx/qla_nx2.c".

commit 51b97e35 upstream. Sasha Levin reports: "gcc5 changes the default standard to c11, which makes kernel build unhappy Explicitly define the kernel standard to be gnu89 which should keep everything working exactly like it was before gcc5" There are multiple small issues with the new default, but the biggest issue seems to be that the old - and very useful - GNU extension to allow a cast in front of an initializer has gone away. Patch updated by Kirill: "I'm pretty sure all gcc versions you can build kernel with supports -std=gnu89. cc-option is redunrant. We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me" Note by Andrew Pinski: "Yes it was reported and both problems relating to this extension has been added to gnu99 and gnu11. Though there are other issues with the kernel dealing with extern inline have different semantics between gnu89 and gnu99/11" End result: we may be able to move up to a newer stdc model eventually, but right now the newer models have some annoying deficiencies, so the traditional "gnu89" model ends up being the preferred one.

commit 6d91857d upstream. With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the opposite thing from older versions of gcc (emits code for an externally linkable version of the inline function). "static inline" does the intended behavior in all cases instead. Signed-off-by:

commit 1a48ff81 upstream. Xbox One controllers require an initialization message to start sending data, so xpad_init_output becomes a required function. The Xbox One controller does not have LEDs like the Xbox 360 controller, so that functionality is not implemented. The format of messages controlling rumble is currently undocumented, so rumble support is not yet implemented. Note that Xbox One controller advertises three interfaces with the same interface class, subclass and protocol, so we have to also match against interface number. Signed-off-by:

commit cd4a4017 upstream. The only users of collect_mounts are in audit_tree.c In audit_trim_trees and audit_add_tree_rule the path passed into collect_mounts is generated from kern_path passed an audit_tree pathname which is guaranteed to be an absolute path. In those cases collect_mounts is obviously intended to work on mounted paths and if a race results in paths that are unmounted when collect_mounts it is reasonable to fail early. The paths passed into audit_tag_tree don't have the absolute path check. But are used to play with fsnotify and otherwise interact with the audit_trees, so again operating only on mounted paths appears reasonable. Avoid having to worry about what happens when we try and audit unmounted filesystems by restricting collect_mounts to mounts that appear in the mount tree. Signed-off-by:

commit dc48e56d upstream. exit_aio() currently serializes killing io contexts. Each context killing ends up having to do percpu_ref_kill(), which in turns has to wait for an RCU grace period. This can take a long time, depending on the number of contexts. And there's no point in doing them serially, when we could be waiting for all of them in one fell swoop. This patches makes my fio thread offload test case exit 0.2s instead of almost 6s. Reviewed-by:

That reduces > the number of lines changed and avoid excessive indentation. OK. To me the code looks better/simpler with "if (ctx)", but this is subjective of course, I won't argue. The patch still removes the empty line between mmap_size = 0 and kill_ioctx(), we reset mmap_size only for kill_ioctx(). But feel free to remove this change. ------------------------------------------------------------------------------- Subject: [PATCH v3 1/2] aio: change exit_aio() to load mm->ioctx_table once and avoid rcu_read_lock() 1. We can read ->ioctx_table only once and we do not read rcu_read_lock() or even rcu_dereference(). This mm has no users, nobody else can play with ->ioctx_table. Otherwise the code is buggy anyway, if we need rcu_read_lock() in a loop because ->ioctx_table can be updated then kfree(table) is obviously wrong. 2. Update the comment. "exit_mmap(mm) is coming" is the good reason to avoid munmap(), but another reason is that we simply can't do vm_munmap() unless current->mm == mm and this is not true in general, the caller is mmput(). 3. We do not really need to nullify mm->ioctx_table before return, probably the current code does this to catch the potential problems. But in this case RCU_INIT_POINTER(NULL) looks better.

commit 3b747298 upstream. Sometimes when the card is restarted it may cause - "irq 16: nobody cared (try booting with the "irqpoll" option)" that is likely caused so, that the card, after the hard reset finishes, pulls on the irq. Disabling the ints before or after the hpsa_kdump_hard_reset_controller fixes it. At this point we can't know in which state the card is, so using SA5_INTR_OFF + SA5_REPLY_INTR_MASK_OFFSET defines directly, instead of the function the drivers provides, seems to be apropriate.

commit a6dfa128 upstream. A huge amount of NIC drivers use the DMA API, however if compiled under 32-bit an very important part of the DMA API can be ommitted leading to the drivers not working at all (especially if used with 'swiotlb=force iommu=soft'). As Prashant Sreedharan explains it: "the driver [tg3] uses DEFINE_DMA_UNMAP_ADDR(), dma_unmap_addr_set() to keep a copy of the dma "mapping" and dma_unmap_addr() to get the "mapping" value. On most of the platforms this is a no-op, but ... with "iommu=soft and swiotlb=force" this house keeping is required, ... otherwise we pass 0 while calling pci_unmap_/pci_dma_sync_ instead of the DMA address." As such enable this even when using 32-bit kernels. Reported-by:

[ upstream commit 78146572 ] nfnl_cthelper_parse_tuple() is called from nfnl_cthelper_new(), nfnl_cthelper_get() and nfnl_cthelper_del(). In each case they pass a pointer to an nf_conntrack_tuple data structure local variable: struct nf_conntrack_tuple tuple; ... ret = nfnl_cthelper_parse_tuple(&tuple, tb[NFCTH_TUPLE]); The problem is that this local variable is not initialized, and nfnl_cthelper_parse_tuple() only initializes two fields: src.l3num and dst.protonum. This leaves all other fields with undefined values based on whatever is on the stack: tuple->src.l3num = ntohs(nla_get_be16(tb[NFCTH_TUPLE_L3PROTONUM])); tuple->dst.protonum = nla_get_u8(tb[NFCTH_TUPLE_L4PROTONUM]); The symptom observed was that when the rpc and tns helpers were added then traffic to port 1536 was being sent to user-space.

commit bc26d4d0 upstream. A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND) on /dev/sequencer with TMR_ECHO midi event. In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning. Compile tested only. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

commit bad4371d upstream. f9fd54f2 ("mmc: sh_mmcif: Use msecs_to_jiffies() for host->timeout") changed the timeout value from 1000 jiffies to 1s. In the case where HZ is 1000 the values are the same. However, for smaller HZ values the timeout is now smaller, 1s instead of 10s in the case of HZ=100. Since the timeout occurs in spite of a normal data transfer a timeout of 10s seems more appropriate. This restores the previous timeout in the case where HZ=100 and results in an increase over the previous timeout for larger values of HZ.

But since RPMB partition is special and can not be accessed by normal eMMC read / write CMDs, it will cause below error messages during kernel boot: ... mmc0: Got data interrupt 0x00000002 even though no data operation was in progress. mmcblk0rpmb: error -110 transferring data, sector 0, nr 32, cmd response 0x900, card status 0xb00 mmcblk0rpmb: retrying using single block read mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 mmcblk0rpmb: timed out sending r/w cmd command, card status 0x400900 end_request: I/O error, dev mmcblk0rpmb, sector 0 Buffer I/O error on device mmcblk0rpmb, logical block 0 end_request: I/O error, dev mmcblk0rpmb, sector 8 Buffer I/O error on device mmcblk0rpmb, logical block 1 end_request: I/O error, dev mmcblk0rpmb, sector 16 Buffer I/O error on device mmcblk0rpmb, logical block 2 end_request: I/O error, dev mmcblk0rpmb, sector 24 Buffer I/O error on device mmcblk0rpmb, logical block 3 ... This patch will discard the access request in eMMC queue if it is RPMB partition access request. By this way, it avoids trigger above error messages.

commit c5272a28 upstream. Way back, when the world was a simpler place and there was no war, no evil, and no kernel bugs, there was just a single pinctrl lock. That was how the world was when (57291ce2 pinctrl: core device tree mapping table parsing support) was written. In that case, there were instances where the pinctrl mutex was already held when pinctrl_register_map() was called, hence a "locked" parameter was passed to the function to indicate that the mutex was already locked (so we shouldn't lock it again). A few years ago in (42fed7ba pinctrl: move subsystem mutex to pinctrl_dev struct), we switched to a separate pinctrl_maps_mutex. ...but (oops) we forgot to re-think about the whole "locked" parameter for pinctrl_register_map(). Basically the "locked" parameter appears to still refer to whether the bigger pinctrl_dev mutex is locked, but we're using it to skip locks of our (now separate) pinctrl_maps_mutex. That's kind of a bad thing(TM). Probably nobody noticed because most of the calls to pinctrl_register_map happen at boot time and we've got synchronous device probing. ...and even cases where we're asynchronous don't end up actually hitting the race too often. ...but after banging my head against the wall for a bug that reproduced 1 out of 1000 reboots and lots of looking through kgdb, I finally noticed this. Anyway, we can now safely remove the "locked" parameter and go back to a war-free, evil-free, and kernel-bug-free world.
