Potentially the timeout may exceed the host->max_busy_timeout. If that becomes the case, mmc_sleep() converts from using an R1B response to an R1 response, as to prevent the host from doing HW busy detection. However, it has turned out that some hosts requires an R1B response no matter what, so let's respect that via checking MMC_CAP_NEED_RSP_BUSY. Note that, if the R1B gets enforced, the host becomes fully responsible of managing the needed busy timeout, in one way or the other.

Donenfeld commit 72c7943792c9e7788ddd182337bcf8f650cf56f5 upstream. When this was originally ported, the 12-byte nonce vectors were left out to keep things simple. I agree that we don't need nor want a library interface for 12-byte nonces. But these test vectors were specially crafted to look at issues in the underlying primitives and related interactions. Therefore, we actually want to keep around all of the test vectors, and simply have a helper function to test them with. Secondly, the sglist-based chunking code in the library interface is rather complicated, so this adds a developer-only test for ensuring that all the book keeping is correct, across a wide array of possibilities.

These missed changes cause slow recovery during backpressure because the corresponding interrupt no longer comes and hence results in Tx throughput drop. So, revert back these missed code changes, as well, which will allow explicitly requesting Tx CIDX updates when backpressure happens. This enables the corresponding interrupt with Tx CIDX update message to get generated and hence speed up recovery and restore back throughput.

This function initializes several pointers, which includes port->hsr after registering rx_handler. So, in the rx_handler routine, un-initialized pointer would be used. In order to fix this, pointers should be initialized before registering rx_handler.

It caused the throughput to be Idleslope[kbps] * (Port transmit rate[kbps] / |Sendslope[kbps]|) where Idleslope * (Port transmit rate / (Idleslope + |Sendslope|)) = Idleslope is expected. In order to fix the issue above, this patch takes the time when the packet sending completes into account by moving the anchor time variable "last" ahead to the send completion time upon transmission and adding wait when the next dequeue request comes before the send completion time of the previous packet. changelog: V2->V3: - remove unnecessary whitespace cleanup - add the checks if port_rate is 0 before division V1->V2: - combine variable "send_completed" into "last" - add the comment for estimate of the packet sending Fixes: 585d763af09c ("net/sched: Introduce Credit Based Shaper (CBS) qdisc") Signed-off-by: Zh-yuan Ye Reviewed-by: Vinicius Costa Gomes Signed-off-by: David S.

Piccoli" [ Upstream commit 428c491332bca498c8eb2127669af51506c346c7 ] Currently ENA only provides the PCI remove() handler, used during rmmod for example. This is not called on shutdown/kexec path; we are potentially creating a failure scenario on kexec: (a) Kexec is triggered, no shutdown() / remove() handler is called for ENA; instead pci_device_shutdown() clears the master bit of the PCI device, stopping all DMA transactions; (b) Kexec reboot happens and the device gets enabled again, likely having its FW with that DMA transaction buffered; then it may trigger the (now invalid) memory operation in the new kernel, corrupting kernel memory area. This patch aims to prevent this, by implementing a shutdown() handler quite similar to the remove() one - the difference being the handling of the netdev, which is unregistered on remove(), but following the convention observed in other drivers, it's only detached on shutdown(). This prevents an odd issue in AWS Nitro instances, in which after the 2nd kexec the next one will fail with an initrd corruption, caused by a wild DMA write to invalid kernel memory.

This is particularly likely with few, large, slots (e.g., GSO packets). Synchronize kernel thread ownership of rx ring slots with a bitmap. Writers acquire a slot race-free by testing tp_status TP_STATUS_KERNEL while holding the sk receive queue lock. They release this lock before copying and set tp_status to TP_STATUS_USER to release to userspace when done. During copying, another writer may take the lock, also see TP_STATUS_KERNEL, and start writing to the same slot. Introduce a new rx_owner_map bitmap with a bit per slot. To acquire a slot, test and set with the lock held. To release race-free, update tp_status and owner bit as a transaction, so take the lock again. This is the one of a variety of discussed options (see Link below): * instead of a shadow ring, embed the data in the slot itself, such as in tp_padding. But any test for this field may match a value left by userspace, causing deadlock. * avoid the lock on release. This leaves a small race if releasing the shadow slot before setting TP_STATUS_USER. The below reproducer showed that this race is not academic. If releasing the slot after tp_status, the race is more subtle. See the first link for details. * add a new tp_status TP_KERNEL_OWNED to avoid the transactional store of two fields. But, legacy applications may interpret all non-zero tp_status as owned by the user. As libpcap does. So this is possible only opt-in by newer processes. It can be added as an optional mode. * embed the struct at the tail of pg_vec to avoid extra allocation. The implementation proved no less complex than a separate field. The additional locking cost on release adds contention, no different than scaling on multicore or multiqueue h/w. In practice, below reproducer nor small packet tcpdump showed a noticeable change in perf report in cycles spent in spinlock. Where contention is problematic, packet sockets support mitigation through PACKET_FANOUT. And we can consider adding opt-in state TP_KERNEL_OWNED. Easy to reproduce by running multiple netperf or similar TCP_STREAM flows concurrently with `tcpdump -B 129 -n greater 60000`. Based on an earlier patchset by Jon Rosen. See links below. I believe this issue goes back to the introduction of tpacket_rcv, which predates git history.

This is due to the lack of RTNL in the deferred rcu work. We queue this work with RTNL in tcindex_change(), later, tcindex_dump() is called: fh = tp->ops->get(tp, t->tcm_handle); ... err = tp->ops->change(..., &fh, ...); tfilter_notify(..., fh, ...); but there is nothing to serialize the pending tcindex_partial_destroy_work() with tcindex_dump(). Fix this by simply holding RTNL in tcindex_partial_destroy_work(), so that it won't be called until RTNL is released after tc_new_tfilter() is completed.

We need to clear skb->dev, otherwise lower layers could interpret the value as a pointer to a netdev.

That commit enabled local loopback to provide an Rx clock from the GENET sourced Tx clk. However, when connected in MII mode the Tx clk is sourced by the PHY so if an EPHY is not supplying clocks (e.g. when the link is down) the UniMAC does not receive the necessary clocks. This commit extends the sw_reset window until the PHY reports that the link is up thereby ensuring that the clocks are being provided to the MAC to produce a clean reset. One consequence is that if the system attempts to enter a Wake on LAN suspend state when the PHY link has not been active the MAC may not have had a chance to initialize cleanly. In this case, we remove the sw_reset and enable the WoL reception path as normal with the hope that the PHY will provide the necessary clocks to drive the WoL blocks if the link becomes active after the system has entered suspend.

Here is the full scenario in detail: * ena_probe() is called when the driver is loaded, the driver is not up yet at the end of ena_probe(). * The number of queues is changed -> io_queue_count is changed as well - ena_up() is not called since the "dev_was_up" boolean in ena_update_queue_count() is false. * ena_up() is called by the kernel (it's called asynchronously some time after ena_probe()). ena_setup_io_intr() is called by ena_up() and it uses io_queue_count to get the suitable irq lines for each msix vector. The function ena_request_io_irq() is called right after that and it uses msix_vecs - This value only changes during ena_probe() and ena_restore() - to request the irq vectors. This results in "Failed to request I/O IRQ" error for i > io_queue_count. Numeric example: * After ena_probe() io_queue_count = 8, msix_vecs = 9. * The number of queues changes to 4 -> io_queue_count = 4, msix_vecs = 9. * ena_up() is executed for the first time: ** ena_setup_io_intr() inits the vectors only up to io_queue_count. ** ena_request_io_irq() calls request_irq() and fails for i = 5. How to reproduce: simply run the following commands: sudo rmmod ena && sudo insmod ena.ko; sudo ethtool -L eth1 combined 3; Fix: Use ENA_MAX_MSIX_VEC(adapter->num_io_queues + adapter->xdp_num_queues) instead of adapter->msix_vecs. We need to take XDP queues into consideration as they need to have msix vectors assigned to them as well. Note that the XDP cannot be attached before the driver is up and running but in XDP mode the issue might occur when the number of queues changes right after a reset trigger. The ENA_MAX_MSIX_VEC simply adds one to the argument since the first msix vector is reserved for management queue.

In case the driver times-out on a keep-alive event, it has high chances of continuously timing-out on keep-alive events. This is because when the driver recovers from the keep-alive-timeout reset the value of last_keep_alive_jiffies is very old, and if a keep-alive event is not received before the next timer expires, the value of last_keep_alive_jiffies will cause another keep-alive-timeout reset and so forth in a loop. Solution: Update last_keep_alive_jiffies whenever the device is restored after reset.

(HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS) These commands send node information to the user-space via generic netlink. But, in the non-init_net namespace, these commands are not allowed because .netnsok flag is false. So, there is no way to get node information in the non-init_net namespace.

We maintain the state of these in-progress WQEs in the RQ SW struct. In the flow of ICOSQ recovery, the corresponding RQ is not in error state, hence: - The buffers of the in-progress WQEs must be released and the RQ metadata should reflect it. - Existing RX WQEs in the RQ should not be affected.

This also fixes the following issue found using kmemleak detector: unreferenced object 0xc2137640 (size 64): comm "swapper/0", pid 1, jiffies 4294937900 (age 3127.400s) hex dump (first 32 bytes): 50 a3 14 c2 80 a2 14 c2 01 00 00 00 20 00 00 00 P........... ... 00 10 00 00 00 80 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<3acd268d>] arch_setup_dma_ops+0x4c/0x104 [<9f7d2cce>] of_dma_configure+0x19c/0x3a4 [] really_probe+0xb0/0x47c [<4f510e4f>] driver_probe_device+0x78/0x1c4 [<7481a0cf>] device_driver_attach+0x58/0x60 [<0ff8f5c1>] __driver_attach+0xb8/0x158 [<86006144>] bus_for_each_dev+0x74/0xb4 [<10159dca>] bus_add_driver+0x1c0/0x200 [<8a265265>] driver_register+0x74/0x108 [] exynos_drm_init+0xb0/0x134 [] do_one_initcall+0x90/0x458 [<6da35917>] kernel_init_freeable+0x188/0x200 [] kernel_init+0x8/0x110 [<1f3cddf9>] ret_from_fork+0x14/0x20 [<8cd12507>] 0x0 unreferenced object 0xc214a280 (size 128): comm "swapper/0", pid 1, jiffies 4294937900 (age 3127.400s) hex dump (first 32 bytes): 00 a0 ec ed 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<3acd268d>] arch_setup_dma_ops+0x4c/0x104 [<9f7d2cce>] of_dma_configure+0x19c/0x3a4 [] really_probe+0xb0/0x47c [<4f510e4f>] driver_probe_device+0x78/0x1c4 [<7481a0cf>] device_driver_attach+0x58/0x60 [<0ff8f5c1>] __driver_attach+0xb8/0x158 [<86006144>] bus_for_each_dev+0x74/0xb4 [<10159dca>] bus_add_driver+0x1c0/0x200 [<8a265265>] driver_register+0x74/0x108 [] exynos_drm_init+0xb0/0x134 [] do_one_initcall+0x90/0x458 [<6da35917>] kernel_init_freeable+0x188/0x200 [] kernel_init+0x8/0x110 [<1f3cddf9>] ret_from_fork+0x14/0x20 [<8cd12507>] 0x0 unreferenced object 0xedeca000 (size 4096): comm "swapper/0", pid 1, jiffies 4294937900 (age 3127.400s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<3acd268d>] arch_setup_dma_ops+0x4c/0x104 [<9f7d2cce>] of_dma_configure+0x19c/0x3a4 [] really_probe+0xb0/0x47c [<4f510e4f>] driver_probe_device+0x78/0x1c4 [<7481a0cf>] device_driver_attach+0x58/0x60 [<0ff8f5c1>] __driver_attach+0xb8/0x158 [<86006144>] bus_for_each_dev+0x74/0xb4 [<10159dca>] bus_add_driver+0x1c0/0x200 [<8a265265>] driver_register+0x74/0x108 [] exynos_drm_init+0xb0/0x134 [] do_one_initcall+0x90/0x458 [<6da35917>] kernel_init_freeable+0x188/0x200 [] kernel_init+0x8/0x110 [<1f3cddf9>] ret_from_fork+0x14/0x20 [<8cd12507>] 0x0 unreferenced object 0xc214a300 (size 128): comm "swapper/0", pid 1, jiffies 4294937900 (age 3127.400s) hex dump (first 32 bytes): 00 a3 14 c2 00 a3 14 c2 00 40 18 c2 00 80 18 c2 .........@...... 02 00 02 00 ad 4e ad de ff ff ff ff ff ff ff ff .....N.......... backtrace: [<08cbd8bc>] iommu_domain_alloc+0x24/0x50 [] arm_iommu_create_mapping+0xe4/0x134 [<3acd268d>] arch_setup_dma_ops+0x4c/0x104 [<9f7d2cce>] of_dma_configure+0x19c/0x3a4 [] really_probe+0xb0/0x47c [<4f510e4f>] driver_probe_device+0x78/0x1c4 [<7481a0cf>] device_driver_attach+0x58/0x60 [<0ff8f5c1>] __driver_attach+0xb8/0x158 [<86006144>] bus_for_each_dev+0x74/0xb4 [<10159dca>] bus_add_driver+0x1c0/0x200 [<8a265265>] driver_register+0x74/0x108 [] exynos_drm_init+0xb0/0x134 [] do_one_initcall+0x90/0x458 [<6da35917>] kernel_init_freeable+0x188/0x200 [] kernel_init+0x8/0x110 [<1f3cddf9>] ret_from_fork+0x14/0x20 Signed-off-by: Marek Szyprowski Reviewed-by: Lukasz Luba Signed-off-by: Inki Dae Signed-off-by: Sasha Levin --- drivers/gpu/drm/exynos/exynos5433_drm_decon.c | 5 ++-- drivers/gpu/drm/exynos/exynos7_drm_decon.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_dma.c | 28 +++++++++++++------ drivers/gpu/drm/exynos/exynos_drm_drv.h | 6 ++-- drivers/gpu/drm/exynos/exynos_drm_fimc.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_fimd.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_g2d.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_gsc.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_rotator.c | 5 ++-- drivers/gpu/drm/exynos/exynos_drm_scaler.c | 6 ++-- drivers/gpu/drm/exynos/exynos_mixer.c | 7 +++-- 11 files changed, 53 insertions(+), 29 deletions(-) diff --git a/drivers/gpu/drm/exynos/exynos5433_drm_decon.c b/drivers/gpu/drm/exynos/exynos5433_drm_decon.c index 2d5cbfda3ca79..9c262daf5816e 100644 --- a/drivers/gpu/drm/exynos/exynos5433_drm_decon.c +++ b/drivers/gpu/drm/exynos/exynos5433_drm_decon.c @@ -55,6 +55,7 @@ static const char * const decon_clks_name[] = { struct decon_context { struct device *dev;

If the device is not present, then the scsi_device is torn down. As a part of scsi_device teardown a workqueue item will be scheduled and the lockups we see are because there are 250k workqueue items to be processed. Accoding to the specification of SIS-64 sas controller, max_channel should be decreased on SIS-64 adapters to 4. The patch fixes softlockup issue.

The issue is that in: strncmp(opt, "eee_timer:", 6) the passed string literal: "eee_timer:" has 10 bytes (without the NULL byte) and the passed size argument is 6. As a result, the logic will also accept other, malformed strings, e.g. "eee_tiXXX:". This bug doesn't seem to have any security impact since its present in module's cmdline parsing code.

The L3 interconnect's memory map is from 0x0 to 0xffffffff. Out of this, System memory (SDRAM) can be accessed from 0x80000000 to 0xffffffff (2GB) DRA7 does support 4GB of SDRAM but upper 2GB can only be accessed by the MPU subsystem. Add the dma-ranges property to reflect the physical address limit of the L3 bus. Issues ere observed only with SATA on DRA7-EVM with 4GB RAM and CONFIG_ARM_LPAE enabled. This is because the controller supports 64-bit DMA and its driver sets the dma_mask to 64-bit thus resulting in DMA accesses beyond L3 limit of 2G. Setting the correct bus_dma_limit fixes the issue.

Without this patch: # perf probe -l \* probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:21@ probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:25@ probe_perf:map__map_ip (on append_inlines:12@util/machine.c in probe_perf:map__map_ip (on unwind_entry:19@util/machine.c in / probe_perf:map__map_ip (on map__map_ip@util/map.h in /home/mhi probe_perf:map__map_ip (on map__map_ip@util/map.h in /home/mhi # perf probe -d \* "*" does not hit any event.

Before with -fcommon those were merged into one defintion. The proper solution would be to to mark this as "extern", however that leads to: dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls] 26 | extern YYLTYPE yylloc; | ^~~~~~ In file included from dtc-lexer.l:24: dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here 127 | extern YYLTYPE yylloc; | ^~~~~~ cc1: all warnings being treated as errors which means the declaration is completely redundant and can just be dropped.

Depending on CONFIG_VMAP_STACK and the THREAD_SIZE / PAGE_SIZE ratio the space for task stacks can be allocated using __vmalloc_node_range(), alloc_pages_node() and kmem_cache_alloc_node(). In the first and the second cases page->mem_cgroup pointer is set, but in the third it's not: memcg membership of a slab page should be determined using the memcg_from_slab_page() function, which looks at page->slab_cache->memcg_params.memcg . In this case, using mod_memcg_page_state() (as in account_kernel_stack()) is incorrect: page->mem_cgroup pointer is NULL even for pages charged to a non-root memory cgroup. It can lead to kernel_stack per-memcg counters permanently showing 0 on some architectures (depending on the configuration). In order to fix it, let's introduce a mod_memcg_obj_state() helper, which takes a pointer to a kernel object as a first argument, uses mem_cgroup_from_obj() to get a RCU-protected memcg pointer and calls mod_memcg_state(). It allows to handle all possible configurations (CONFIG_VMAP_STACK and various THREAD_SIZE/PAGE_SIZE values) without spilling any memcg/kmem specifics into fork.c .

Commit aa23ca3d98f7 ("gpiolib: acpi: Add honor_wakeup module-option + quirk mechanism") was added to deal with spurious wakeups on one specific model of the HP x2 10 series. The approach taken there was to add a bool controlling wakeup support for all ACPI GPIO events. This was sufficient for the specific HP x2 10 model the commit was trying to fix, but in the mean time other models have turned up which need a similar workaround to avoid spurious wakeups from suspend, but only for one of the pins on which the ACPI tables request ACPI GPIO events. Since the honor_wakeup option was added to be able to ignore wake events, the name was perhaps not the best, this commit renames it to ignore_wake and changes it to a string with the following format: gpiolib_acpi.ignore_wake=controller@pin[,controller@pin[,...]] This allows working around spurious wakeup issues on a per pin basis. This commit also reworks the existing quirk for the HP x2 10 so that it functions as before. Note: -This removes the honor_wakeup parameter. This has only been upstream for a short time and to the best of my knowledge there are no users using this module parameter. -The controller@pin[,controller@pin[,...]] syntax is based on an existing kernel module parameter using the same controller@pin format. That version uses ';' as separator, but in practice that is problematic because grub2 cannot handle this without taking special care to escape the ';', so here we are using a ',' as separator instead which does not have this issue.

When an AFS service handler function aborts a call, AF_RXRPC marks the call as complete - which means that it's not going to get any more packets from the receiver. This is a problem because reception of the final ACK is what triggers afs_deliver_to_call() to drop the final ref on the afs_call object. Instead, aborted AFS service calls may then just sit around waiting for ever or until they're displaced by a new call on the same connection channel or a connection-level abort. Fix this by calling afs_set_call_complete() to finalise the afs_call struct representing the call. However, we then need to drop the ref that stops the call from being deallocated. We can do this in afs_set_call_complete(), as the work queue is holding a separate ref of its own, but then we shouldn't do it in afs_process_async_call() and afs_delete_async_call(). call->drop_ref is set to indicate that a ref needs dropping for a call and this is dealt with when we transition a call to AFS_CALL_COMPLETE. But then we also need to get rid of the ref that pins an asynchronous client call. We can do this by the same mechanism, setting call->drop_ref for an async client call too. We can also get rid of call->incoming since nothing ever sets it and only one thing ever checks it (futilely). A trace of the rxrpc_call and afs_call struct ref counting looks like: -0 [001] ..s5 164.764892: rxrpc_call: c=00000002 SEE u=3 sp=rxrpc_new_incoming_call+0x473/0xb34 a=00000000442095b5 -0 [001] .Ns5 164.766001: rxrpc_call: c=00000002 QUE u=4 sp=rxrpc_propose_ACK+0xbe/0x551 a=00000000442095b5 -0 [001] .Ns4 164.766005: rxrpc_call: c=00000002 PUT u=3 sp=rxrpc_new_incoming_call+0xa3f/0xb34 a=00000000442095b5 -0 [001] .Ns7 164.766433: afs_call: c=00000002 WAKE u=2 o=11 sp=rxrpc_notify_socket+0x196/0x33c kworker/1:2-1810 [001] ...1 164.768409: rxrpc_call: c=00000002 SEE u=3 sp=rxrpc_process_call+0x25/0x7ae a=00000000442095b5 kworker/1:2-1810 [001] ...1 164.769439: rxrpc_tx_packet: c=00000002 e9f1a7a8:95786a88:00000008:09c5 00000001 00000000 02 22 ACK CallAck kworker/1:2-1810 [001] ...1 164.769459: rxrpc_call: c=00000002 PUT u=2 sp=rxrpc_process_call+0x74f/0x7ae a=00000000442095b5 kworker/1:2-1810 [001] ...1 164.770794: afs_call: c=00000002 QUEUE u=3 o=12 sp=afs_deliver_to_call+0x449/0x72c kworker/1:2-1810 [001] ...1 164.770829: afs_call: c=00000002 PUT u=2 o=12 sp=afs_process_async_call+0xdb/0x11e kworker/1:2-1810 [001] ...2 164.771084: rxrpc_abort: c=00000002 95786a88:00000008 s=0 a=1 e=1 K-1 kworker/1:2-1810 [001] ...1 164.771461: rxrpc_tx_packet: c=00000002 e9f1a7a8:95786a88:00000008:09c5 00000002 00000000 04 00 ABORT CallAbort kworker/1:2-1810 [001] ...1 164.771466: afs_call: c=00000002 PUT u=1 o=12 sp=SRXAFSCB_ProbeUuid+0xc1/0x106 The abort generated in SRXAFSCB_ProbeUuid(), labelled "K-1", indicates that the local filesystem/cache manager didn't recognise the UUID as its own.

The handling of notify->work did not properly maintain notify->kref in two cases: 1) where the work was already scheduled, another irq_set_affinity_locked() would get the ref and (no-op-ly) schedule the work. Thus when irq_affinity_notify() ran, it would drop the original ref but not the additional one. 2) when cancelling the (old) work in irq_set_affinity_notifier(), if there was outstanding work a ref had been got for it but was never put. Fix both by checking the return values of the work handling functions (schedule_work() for (1) and cancel_work_sync() for (2)) and put the extra ref if the return value indicates preexisting work.

Fix the handling of signals in client rxrpc calls made by the afs filesystem. Ignore signals completely, leaving call abandonment or connection loss to be detected by timeouts inside AF_RXRPC. Allowing a filesystem call to be interrupted after the entire request has been transmitted and an abort sent means that the server may or may not have done the action - and we don't know. It may even be worse than that for older servers.

The current x32 BPF JIT is incorrect for JMP32 JSET BPF_X when the upper 32 bits of operand registers are non-zero in certain situations. The problem is in the following code: case BPF_JMP | BPF_JSET | BPF_X: case BPF_JMP32 | BPF_JSET | BPF_X: ... /* and dreg_lo,sreg_lo */ EMIT2(0x23, add_2reg(0xC0, sreg_lo, dreg_lo)); /* and dreg_hi,sreg_hi */ EMIT2(0x23, add_2reg(0xC0, sreg_hi, dreg_hi)); /* or dreg_lo,dreg_hi */ EMIT2(0x09, add_2reg(0xC0, dreg_lo, dreg_hi)); This code checks the upper bits of the operand registers regardless if the BPF instruction is BPF_JMP32 or BPF_JMP64. Registers dreg_hi and dreg_lo are not loaded from the stack for BPF_JMP32, however, they can still be polluted with values from previous instructions. The following BPF program demonstrates the bug. The jset64 instruction loads the temporary registers and performs the jump, since ((u64)r7 & (u64)r8) is non-zero. The jset32 should _not_ be taken, as the lower 32 bits are all zero, however, the current JIT will take the branch due the pollution of temporary registers from the earlier jset64. mov64 r0, 0 ld64 r7, 0x8000000000000000 ld64 r8, 0x8000000000000000 jset64 r7, r8, 1 exit jset32 r7, r8, 1 mov64 r0, 2 exit The expected return value of this program is 2; under the buggy x32 JIT it returns 0. The fix is to skip using the upper 32 bits for jset32 and compare the upper 32 bits for jset64 only. All tests in test_bpf.ko and selftests/bpf/test_verifier continue to pass with this change. We found this bug using our automated verification tool, Serval.

This fixes OTG mode detection and charging issues on TBS A711 tablet. The issues came from ID pin reading 0, causing host mode to be enabled, when it should not be, leading to DRVVBUS being enabled, which disabled the charger.
