commit 7e1d90f6 upstream. commit 4842e98f ("ALSA: seq: Fix race at creating a queue") attempted to fix a race reported by syzkaller. That fix has been described as follows: " When a sequencer queue is created in snd_seq_queue_alloc(),it adds the new queue element to the public list before referencing it. Thus the queue might be deleted before the call of snd_seq_queue_use(), and it results in the use-after-free error, as spotted by syzkaller. The fix is to reference the queue object at the right time. " Even with that fix in place, syzkaller reported a use-after-free error. It specifically pointed to the last instruction "return q->queue" in snd_seq_queue_alloc(). The pointer q is being used after kfree() has been called on it. It turned out that there is still a small window where a race can happen. The window opens at snd_seq_ioctl_create_queue()->snd_seq_queue_alloc()->queue_list_add() and closes at snd_seq_ioctl_create_queue()->queueptr()->snd_use_lock_use(). Between these two calls, a different thread could delete the queue and possibly re-create a different queue in the same location in queue_list. This change prevents this situation by calling snd_use_lock_use() from snd_seq_queue_alloc() prior to calling queue_list_add(). It is then the caller's responsibility to call snd_use_lock_free(&q->use_lock). Fixes: 4842e98f ("ALSA: seq: Fix race at creating a queue") Reported-by:

commit 9c3f3794 upstream. If one cpu is doing nf_ct_extend_unregister while another cpu is doing __nf_ct_ext_add_length, then we may hit BUG_ON(t == NULL). Moreover, there's no synchronize_rcu invocation after set nf_ct_ext_types[id] to NULL, so it's possible that we may access invalid pointer. But actually, most of the ct extends are built-in, so the problem listed above will not happen. However, there are two exceptions: NF_CT_EXT_NAT and NF_CT_EXT_SYNPROXY. For _EXT_NAT, the panic will not happen, since adding the nat extend and unregistering the nat extend are located in the same file(nf_nat_core.c), this means that after the nat module is removed, we cannot add the nat extend too. For _EXT_SYNPROXY, synproxy extend may be added by init_conntrack, while synproxy extend unregister will be done by synproxy_core_exit. So after nf_synproxy_core.ko is removed, we may still try to add the synproxy extend, then kernel panic may happen. I know it's very hard to reproduce this issue, but I can play a tricky game to make it happen very easily :) Step 1. Enable SYNPROXY for tcp dport 1234 at FORWARD hook: # iptables -I FORWARD -p tcp --dport 1234 -j SYNPROXY Step 2. Queue the syn packet to the userspace at raw table OUTPUT hook. Also note, in the userspace we only add a 20s' delay, then reinject the syn packet to the kernel: # iptables -t raw -I OUTPUT -p tcp --syn -j NFQUEUE --queue-num 1 Step 3. Using "nc 2.2.2.2 1234" to connect the server. Step 4. Now remove the nf_synproxy_core.ko quickly: # iptables -F FORWARD # rmmod ipt_SYNPROXY # rmmod nf_synproxy_core Step 5. After 20s' delay, the syn packet is reinjected to the kernel. Now you will see the panic like this: kernel BUG at net/netfilter/nf_conntrack_extend.c:91! Call Trace: ? __nf_ct_ext_add_length+0x53/0x3c0 [nf_conntrack] init_conntrack+0x12b/0x600 [nf_conntrack] nf_conntrack_in+0x4cc/0x580 [nf_conntrack] ipv4_conntrack_local+0x48/0x50 [nf_conntrack_ipv4] nf_reinject+0x104/0x270 nfqnl_recv_verdict+0x3e1/0x5f9 [nfnetlink_queue] ? nfqnl_recv_verdict+0x5/0x5f9 [nfnetlink_queue] ? nla_parse+0xa0/0x100 nfnetlink_rcv_msg+0x175/0x6a9 [nfnetlink] [...] One possible solution is to make NF_CT_EXT_SYNPROXY extend built-in, i.e. introduce nf_conntrack_synproxy.c and only do ct extend register and unregister in it, similar to nf_conntrack_timeout.c. But having such a obscure restriction of nf_ct_extend_unregister is not a good idea, so we should invoke synchronize_rcu after set nf_ct_ext_types to NULL, and check the NULL pointer when do __nf_ct_ext_add_length. Then it will be easier if we add new ct extend in the future. Last, we use kfree_rcu to free nf_ct_ext, so rcu_barrier() is unnecessary anymore, remove it too. Signed-off-by:

commit 68fe5568 upstream. Fix a commit 3021773c ("MIPS: DEC: Avoid la pseudo-instruction in delay slots") regression and remove assembly errors: arch/mips/dec/int-handler.S: Assembler messages: arch/mips/dec/int-handler.S:162: Error: Macro used $at after ".set noat" arch/mips/dec/int-handler.S:163: Error: Macro used $at after ".set noat" arch/mips/dec/int-handler.S:229: Error: Macro used $at after ".set noat" arch/mips/dec/int-handler.S:230: Error: Macro used $at after ".set noat" triggering with with the CPU_DADDI_WORKAROUNDS option set and the DADDIU instruction. This is because with that option in place the instruction becomes a macro, which expands to an LI/DADDU (or actually ADDIU/DADDU) sequence that uses $at as a temporary register. With CPU_DADDI_WORKAROUNDS we only support `-msym32' compilation though, and this is already enforced in arch/mips/Makefile, so choose the 32-bit expansion variant for the supported configurations and then replace the 64-bit variant with #error just in case.

commit 3fa53ec2 upstream. The irq chip callbacks irq_request/release_resources() have absolutely no business with masking and unmasking the irq. The core code unmasks the interrupt after complete setup and masks it before invoking irq_release_resources().

commit d81ece74 upstream. The PH16 pin has a function with mux id 0x5, which is the DET pin of the "sim" (smart card reader) IP block. This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver. Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now. Fixes: f2821b1c ("pinctrl: sunxi: Move Allwinner A10 pinctrl driver to a driver of its own") Signed-off-by:

commit e788787e upstream. Certain HP keyboards would keep inputting a character automatically which is the wake-up key after S3 resume On some AMD platforms USB host fails to respond (by holding resume-K) to USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures that resume is signaled for at least 20 ms (TDRSMDN), which is defined in USB 2.0 spec. The result is that the keyboard is out of function. In SNPS USB design, the host responds to the resume request only after system gets back to S0 and the host gets to functional after the internal HW restore operation that is more than 1 second after the initial resume request from the USB device. As a workaround for specific keyboard ID(HP Keyboards), applying port reset after resume when the keyboard is plugged in. Signed-off-by:

commit 2eac1362 upstream. While unlink an urb, if the urb has been programmed in the controller, the controller driver might do some hw related actions to tear down the urb. Currently usb_hcd_flush_endpoint() passes each urb from the head of the endpoint's urb_list to the controller driver, which could make the controller driver think each urb has been programmed and take the unnecessary actions for each urb. This patch changes the behavior in usb_hcd_flush_endpoint() to pass the urbs from the tail of the list, to avoid any unnecessary actions in an controller driver. Acked-by:

commit 94c43b98 upstream. Some buggy USB disk adapters disconnect and reconnect multiple times during the enumeration procedure. This may lead to a device connecting at full speed instead of high speed, because when the USB stack sees that a device isn't able to enumerate at high speed, it tries to hand the connection over to a full-speed companion controller. The logic for doing this is careful to check that the device is still connected. But this check is inadequate if the device disconnects and reconnects before the check is done. The symptom is that a device works, but much more slowly than it is capable of operating. The situation was made worse recently by commit 22547c4c ("usb: hub: Wait for connection to be reestablished after port reset"), which increases the delay following a reset before a disconnect is recognized, thus giving the device more time to reconnect. This patch makes the check more robust. If the device was disconnected at any time during enumeration, we will now skip the full-speed handover. Signed-off-by:

commit 2acecd58 upstream. The latest HW manual (Rev.0.55) shows us this UGCTRL2.VBUSSEL bit. If the bit sets to 1, the VBUS drive is controlled by phy related registers (called "UCOM Registers" on the manual). Since R-Car Gen3 environment will control VBUS by phy-rcar-gen3-usb2 driver, the UGCTRL2.VBUSSEL bit should be set to 1. So, this patch fixes the register's value. Otherwise, even if the ID pin indicates to peripheral, the R-Car will output USBn_PWEN to 1 when a host driver is running.

However, sometimes usb3_request_done() function is called with interrupts enabled. So, this function should be held by spin_lock_irqsave() to disable interruption. Also, this driver has to call spin_unlock() to avoid spinlock recursion by this driver before calling usb_gadget_giveback_request(). Reported-by:

commit a3507e48 upstream. The TSL2563 driver provides three iio channels, two of which are raw ADC channels (channel 0 and channel 1) in the device and the remaining one is calculated by the two. The ADC channel 0 only supports programmable interrupt with threshold settings and this driver supports the event but the generated event code does not contain the corresponding iio channel type. This is going to change userspace ABI. Hopefully fixing this to be what it should always have been won't break any userspace code. Cc: Jonathan Cameron <jic23@kernel.org> Signed-off-by:

commit e59e1898 upstream. After probe we would put the device in normal mode, after a runtime suspend-resume we would put it back in normal mode. But for a regular suspend-resume we would only put it back in normal mode if triggers or events have been requested. This is not consistent and breaks reading raw values after a suspend-resume. This commit changes the regular resume path to also unconditionally put the device back in normal mode, fixing reading of raw values not working after a regular suspend-resume cycle. Signed-off-by:

This fixes the following KASAN warning: [ 197.020857] [IGT] kms_pipe_color: executing [ 197.063434] [IGT] kms_pipe_color: starting subtest ctm-0-25-pipe0 [ 197.078989] ================================================================== [ 197.079127] BUG: KASAN: slab-out-of-bounds in bdw_load_gamma_lut.isra.2+0x3b9/0x570 [i915] [ 197.079188] Read of size 2 at addr ffff8800d38db150 by task kms_pipe_color/1839 [ 197.079208] CPU: 2 PID: 1839 Comm: kms_pipe_color Tainted: G U 4.13.0-rc1-patser+ #5211 [ 197.079215] Hardware name: NUC5i7RYB, BIOS RYBDWi35.86A.0246.2015.0309.1355 03/09/2015 [ 197.079220] Call Trace: [ 197.079230] dump_stack+0x68/0x9e [ 197.079239] print_address_description+0x6f/0x250 [ 197.079251] kasan_report+0x216/0x370 [ 197.079374] ? bdw_load_gamma_lut.isra.2+0x3b9/0x570 [i915] [ 197.079451] ? gen8_write16+0x4e0/0x4e0 [i915] [ 197.079460] __asan_report_load2_noabort+0x14/0x20 [ 197.079535] bdw_load_gamma_lut.isra.2+0x3b9/0x570 [i915] [ 197.079612] broadwell_load_luts+0x1df/0x550 [i915] [ 197.079690] intel_color_load_luts+0x7b/0x80 [i915] [ 197.079764] intel_begin_crtc_commit+0x138/0x760 [i915] [ 197.079783] drm_atomic_helper_commit_planes_on_crtc+0x1a3/0x820 [drm_kms_helper] [ 197.079859] ? intel_pre_plane_update+0x571/0x580 [i915] [ 197.079937] intel_update_crtc+0x238/0x330 [i915] [ 197.080016] intel_update_crtcs+0x10f/0x210 [i915] [ 197.080092] intel_atomic_commit_tail+0x1552/0x3340 [i915] [ 197.080101] ? _raw_spin_unlock+0x3c/0x40 [ 197.080110] ? __queue_work+0xb40/0xbf0 [ 197.080188] ? skl_update_crtcs+0xc00/0xc00 [i915] [ 197.080195] ? trace_hardirqs_on+0xd/0x10 [ 197.080269] ? intel_atomic_commit_ready+0x128/0x13c [i915] [ 197.080329] ? __i915_sw_fence_complete+0x5b8/0x6d0 [i915] [ 197.080336] ? debug_object_activate+0x39e/0x580 [ 197.080397] ? i915_sw_fence_await+0x30/0x30 [i915] [ 197.080409] ? __might_sleep+0x15b/0x180 [ 197.080483] intel_atomic_commit+0x944/0xa70 [i915] [ 197.080490] ? refcount_dec_and_test+0x11/0x20 [ 197.080567] ? intel_atomic_commit_tail+0x3340/0x3340 [i915] [ 197.080597] ? drm_atomic_crtc_set_property+0x303/0x580 [drm] [ 197.080674] ? intel_atomic_commit_tail+0x3340/0x3340 [i915] [ 197.080704] drm_atomic_commit+0xd7/0xe0 [drm] [ 197.080722] drm_atomic_helper_crtc_set_property+0xec/0x130 [drm_kms_helper] [ 197.080749] drm_mode_crtc_set_obj_prop+0x7d/0xb0 [drm] [ 197.080775] drm_mode_obj_set_property_ioctl+0x50b/0x5d0 [drm] [ 197.080783] ? __might_fault+0x104/0x180 [ 197.080809] ? drm_mode_obj_find_prop_id+0x160/0x160 [drm] [ 197.080838] ? drm_mode_obj_find_prop_id+0x160/0x160 [drm] [ 197.080861] drm_ioctl_kernel+0x154/0x1a0 [drm] [ 197.080885] drm_ioctl+0x624/0x8f0 [drm] [ 197.080910] ? drm_mode_obj_find_prop_id+0x160/0x160 [drm] [ 197.080934] ? drm_getunique+0x210/0x210 [drm] [ 197.080943] ? __handle_mm_fault+0x1bd0/0x1ce0 [ 197.080949] ? lock_downgrade+0x610/0x610 [ 197.080957] ? __lru_cache_add+0x15a/0x180 [ 197.080967] do_vfs_ioctl+0xd92/0xe40 [ 197.080975] ? ioctl_preallocate+0x1b0/0x1b0 [ 197.080982] ? selinux_capable+0x20/0x20 [ 197.080991] ? __do_page_fault+0x7b7/0x9a0 [ 197.080997] ? lock_downgrade+0x5bb/0x610 [ 197.081007] ? security_file_ioctl+0x57/0x90 [ 197.081016] SyS_ioctl+0x4e/0x80 [ 197.081024] entry_SYSCALL_64_fastpath+0x18/0xad [ 197.081030] RIP: 0033:0x7f61f287a987 [ 197.081035] RSP: 002b:00007fff7d44d188 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 [ 197.081043] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f61f287a987 [ 197.081048] RDX: 00007fff7d44d1c0 RSI: 00000000c01864ba RDI: 0000000000000003 [ 197.081053] RBP: 00007f61f2b3eb00 R08: 0000000000000059 R09: 0000000000000000 [ 197.081058] R10: 0000002ea5c4a290 R11: 0000000000000246 R12: 00007f61f2b3eb58 [ 197.081063] R13: 0000000000001010 R14: 00007f61f2b3eb58 R15: 0000000000002702 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101659Signed-off-by:

commit f7f8c175 upstream. When using soft ecc, if no ooblayout is given, the core automatically uses one of the nand_ooblayout_{sp,lp}*() functions to determine the layout inside the out of band data. Until kernel version 4.6, struct nand_ecclayout was used for that purpose. During the migration from 4.6 to 4.7, an error shown up in the small page layout, in the case oob section is only 8 bytes long. The layout was using three bytes (0, 1, 2) for ecc, two bytes (3, 4) as free bytes, one byte (5) for bad block marker and finally two bytes (6, 7) as free bytes, as shown there: [linux-4.6] drivers/mtd/nand/nand_base.c:52 static struct nand_ecclayout nand_oob_8 = { .eccbytes = 3, .eccpos = {0, 1, 2}, .oobfree = { {.offset = 3, .length = 2}, {.offset = 6, .length = 2} } }; This fixes the current implementation which is incoherent. It references bit 3 at the same time as an ecc byte and a free byte. Furthermore, it is clear with the previous implementation that there is only one ecc section with 8 bytes oob sections. We shall return -ERANGE in the nand_ooblayout_ecc_sp() function when asked for the second section. Signed-off-by:

commit 68227c03 upstream. Before the patch, the flock flag could remain uninitialized for the lifespan of the fuse_file allocation. Unless set to true in fuse_file_flock(), it would remain in an indeterminate state until read in an if statement in fuse_release_common(). This could consequently lead to taking an unexpected branch in the code. The bug was discovered by a runtime instrumentation designed to detect use of uninitialized memory in the kernel.
