[ Upstream commit 212ed75d ] The pipapo set backend follows copy-on-update approach, maintaining one clone of the existing datastructure that is being updated. The clone and current datastructures are swapped via rcu from the commit step. The existing integration with the commit protocol is flawed because there is no operation to clean up the clone if the transaction is aborted. Moreover, the datastructure swap happens on set element activation. This patch adds two new operations for sets: commit and abort, these new operations are invoked from the commit and abort steps, after the transactions have been digested, and it updates the pipapo set backend to use it. This patch adds a new ->pending_update field to sets to maintain a list of sets that require this new commit and abort operations.

[ Upstream commit c5c31fb7 ] The DSPI controller has configurable timing for (a) tCSC: the interval between the assertion of the chip select and the first clock edge (b) tASC: the interval between the last clock edge and the deassertion of the chip select What is a bit surprising, but is documented in the figure "Example of continuous transfer (CPHA=1, CONT=1)" in the datasheet, is that when the chip select stays asserted between multiple TX FIFO writes, the tCSC and tASC times still apply. With CONT=1, chip select remains asserted, but SCK takes a break and goes to the idle state for tASC + tCSC ns. In other words, the default values (of 0 and 0 ns) result in SCK glitches where the SCK transition to the idle state, as well as the SCK transition from the idle state, will have no delay in between, and it may appear that a SCK cycle has simply gone missing. The resulting timing violation might cause data corruption in many peripherals, as their chip select is asserted. The driver has device tree bindings for tCSC ("fsl,spi-cs-sck-delay") and tASC ("fsl,spi-sck-cs-delay"), but these are only specified to apply when the chip select toggles in the first place, and this timing characteristic depends on each peripheral. Many peripherals do not have explicit timing requirements, so many device trees do not have these properties present at all. Nonetheless, the lack of SCK glitches is a common sense requirement, and since the SCK stays in the idle state during transfers for tCSC+tASC ns, and that in itself should look like half a cycle, then let's ensure that tCSC and tASC are at least a quarter of a SCK period, such that their sum is at least half of one.

[ Upstream commit b0068342 ] There is a reference count error in error path code and a potential race in check_rkey() in rxe_resp.c. When looking up the rkey for a memory window the reference to the mw from rxe_lookup_mw() is dropped before a reference is taken on the mr referenced by the mw. If the mr is destroyed immediately after the call to rxe_put(mw) the mr pointer is unprotected and may end up pointing at freed memory. The rxe_get(mr) call should take place before the rxe_put(mw) call. All errors in check_rkey() call rxe_put(mw) if mw is not NULL but it was already called after the above. The mw pointer should be set to NULL after the rxe_put(mw) call to prevent this from happening.

[ Upstream commit 9a3763e8 ] In rxe_net.c a received packet, from udp or loopback, is passed to rxe_rcv() in rxe_recv.c as a udp packet. I.e. skb->data is pointing at the udp header. But rxe_rcv() makes length checks to verify the packet is long enough to hold the roce headers as if it were a roce packet. I.e. skb->data pointing at the bth header. A runt packet would appear to have 8 more bytes than it actually does which may lead to incorrect behavior. This patch calls skb_pull() to adjust the skb to point at the bth header before calling rxe_rcv() which fixes this error.

[ Upstream commit 9c29c8c7 ] In current design: 1. PD and clt_path->s.dev are shared among connections. 2. every con[n]'s cleanup phase will call destroy_con_cq_qp() 3. clt_path->s.dev will be always decreased in destroy_con_cq_qp(), and when clt_path->s.dev become zero, it will destroy PD. 4. when con[1] failed to create, con[1] will not take clt_path->s.dev, but it try to decreased clt_path->s.dev So, in case create_cm(con[0]) succeeds but create_cm(con[1]) fails, destroy_con_cq_qp(con[1]) will be called first which will destroy the PD while this PD is still taken by con[0]. Here, we refactor the error path of create_cm() and init_conns(), so that we do the cleanup in the order they are created. The warning occurs when destroying RXE PD whose reference count is not zero. rnbd_client L597: Mapping device /dev/nvme0n1 on session client, (access_mode: rw, nr_poll_queues: 0) ------------[ cut here ]------------ WARNING: CPU: 0 PID: 26407 at drivers/infiniband/sw/rxe/rxe_pool.c:256 __rxe_cleanup+0x13a/0x170 [rdma_rxe] Modules linked in: rpcrdma rdma_ucm ib_iser rnbd_client libiscsi rtrs_client scsi_transport_iscsi rtrs_core rdma_cm iw_cm ib_cm crc32_generic rdma_rxe udp_tunnel ib_uverbs ib_core kmem device_dax nd_pmem dax_pmem nd_vme crc32c_intel fuse nvme_core nfit libnvdimm dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua dm_mirror dm_region_hash dm_log dm_mod CPU: 0 PID: 26407 Comm: rnbd-client.sh Kdump: loaded Not tainted 6.2.0-rc6-roce-flush+ #53 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014 RIP: 0010:__rxe_cleanup+0x13a/0x170 [rdma_rxe] Code: 45 84 e4 0f 84 5a ff ff ff 48 89 ef e8 5f 18 71 f9 84 c0 75 90 be c8 00 00 00 48 89 ef e8 be 89 1f fa 85 c0 0f 85 7b ff ff ff <0f> 0b 41 bc ea ff ff ff e9 71 ff ff ff e8 84 7f 1f fa e9 d0 fe ff RSP: 0018:ffffb09880b6f5f0 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff99401f15d6a8 RCX: 0000000000000000 RDX: 0000000000000001 RSI: ffffffffbac8234b RDI: 00000000ffffffff RBP: ffff99401f15d6d0 R08: 0000000000000001 R09: 0000000000000001 R10: 0000000000002d82 R11: 0000000000000000 R12: 0000000000000001 R13: ffff994101eff208 R14: ffffb09880b6f6a0 R15: 00000000fffffe00 FS: 00007fe113904740(0000) GS:ffff99413bc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ff6cde656c8 CR3: 000000001f108004 CR4: 00000000001706f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> rxe_dealloc_pd+0x16/0x20 [rdma_rxe] ib_dealloc_pd_user+0x4b/0x80 [ib_core] rtrs_ib_dev_put+0x79/0xd0 [rtrs_core] destroy_con_cq_qp+0x8a/0xa0 [rtrs_client] init_path+0x1e7/0x9a0 [rtrs_client] ? __pfx_autoremove_wake_function+0x10/0x10 ? lock_is_held_type+0xd7/0x130 ? rcu_read_lock_sched_held+0x43/0x80 ? pcpu_alloc+0x3dd/0x7d0 ? rtrs_clt_init_stats+0x18/0x40 [rtrs_client] rtrs_clt_open+0x24f/0x5a0 [rtrs_client] ? __pfx_rnbd_clt_link_ev+0x10/0x10 [rnbd_client] rnbd_clt_map_device+0x6a5/0xe10 [rnbd_client] Fixes: 6a98d71d ("RDMA/rtrs: client: main functionality") Link: https://lore.kernel.org/r/1682384563-2-4-git-send-email-lizhijian@fujitsu.com Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Acked-by: Jack Wang <jinpu.wang@ionos.com> Tested-by: Jack Wang <jinpu.wang@ionos.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>

commit 00f8205f upstream. Consider a scenario where cable disconnect happens when there is an active usb reqest queued to the UDC. As part of the disconnect we would issue an end transfer with no interrupt-on-completion before giving back this request. Since we are giving back the request without skipping TRBs the num_trbs field of dwc3_request still holds the stale value previously used. Function drivers re-use same request for a given bind-unbind session and hence their dwc3_request context gets preserved across cable disconnect/connect. When such a request gets re-queued after cable connect, we would increase the num_trbs field on top of the previous stale value thus incorrectly representing the number of TRBs used. Fix this by resetting num_trbs field before giving back the request.

commit d2d69354 upstream. The Qualcomm dwc3 glue driver is currently accessing the driver data of the child core device during suspend and on wakeup interrupts. This is clearly a bad idea as the child may not have probed yet or could have been unbound from its driver. The first such layering violation was part of the initial version of the driver, but this was later made worse when the hack that accesses the driver data of the grand child xhci device to configure the wakeup interrupts was added. Fixing this properly is not that easily done, so add a sanity check to make sure that the child driver data is non-NULL before dereferencing it for now. Note that this relies on subtleties like the fact that driver core is making sure that the parent is not suspended while the child is probing.

commit 286d9975 upstream. usb_udc_connect_control(), soft_connect_store() and usb_gadget_deactivate() can potentially race against each other to invoke usb_gadget_connect()/usb_gadget_disconnect(). To prevent this, guard udc->started, gadget->allow_connect, gadget->deactivate and gadget->connect with connect_lock so that ->pullup() is only invoked when the gadget is bound, started and not deactivated. The routines usb_gadget_connect_locked(), usb_gadget_disconnect_locked(), usb_udc_connect_control_locked(), usb_gadget_udc_start_locked(), usb_gadget_udc_stop_locked() are called with this lock held. An earlier version of this commit was reverted due to the crash reported in https://lore.kernel.org/all/ZF4BvgsOyoKxdPFF@francesco-nb.int.toradex.com/ . commit 16737e78d190 ("usb: gadget: udc: core: Offload usb_udc_vbus_handler processing") addresses the crash reported.

commit 50966da8 upstream. usb_udc_vbus_handler() can be invoked from interrupt context by irq handlers of the gadget drivers, however, usb_udc_connect_control() has to run in non-atomic context due to the following: a. Some of the gadget driver implementations expect the ->pullup callback to be invoked in non-atomic context. b. usb_gadget_disconnect() acquires udc_lock which is a mutex. Hence offload invocation of usb_udc_connect_control() to workqueue. UDC should not be pulled up unless gadget driver is bound. The new flag "allow_connect" is now set by gadget_bind_driver() and cleared by gadget_unbind_driver(). This prevents work item to pull up the gadget even if queued when the gadget driver is already unbound.

commit 3fe95742 upstream. If the boot firmware has already established tunnels, especially ones that have special requirements from the link such as DisplayPort, we should not blindly enable CL states (nor change the TMU configuration). Otherwise the existing tunnels may not work as expected. For this reason, skip the CL state enabling when we go over the existing topology. This will also keep the TMU settings untouched because we do not change the TMU configuration when CL states are not enabled.

commit c8a5d5ea upstream. This seems to have existed for ever but is now more apparant after commit 9bff18d1 ("drm/ttm: use per BO cleanup workers") My analysis: two threads are running, one in the irq signalling the fence, in dma_fence_signal_timestamp_locked, it has done the DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the callbacks. The second thread in nouveau_cli_work_ready, where it sees the fence is signalled, so then puts the fence, cleanups the object and frees the work item, which contains the callback. Thread one goes again and tries to call the callback and causes the use-after-free. Proposed fix: lock the fence signalled check in nouveau_cli_work_ready, so either the callbacks are done or the memory is freed.

commit 122e2cb7 upstream. This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for HEM devices which supports native DSD. Prior to this change Linux kernel was not enabling native DSD playback for HEM devices, and as a result, DSD audio was being converted to PCM "on the fly". HEM devices, when connected to the system, would only play audio in PCM format, even if the source material was in DSD format. With the addition of new VENDOR_FLG in the quircks.c file, the devices are now correctly recognized, and raw DSD data is transmitted to the device, allowing for native DSD playback.

commit 8ba61c9f upstream. As reported in the bugzilla below, the PM resume of a UAC3 device may fail due to the incomplete power state change, stuck at D1. The reason is that the driver expects the full D0 power state change only at hw_params, while the normal PCM resume procedure doesn't call hw_params. For fixing the bug, we add the same power state update to D0 at the prepare callback, which is certainly called by the resume procedure. Note that, with this change, the power state change in the hw_params becomes almost redundant, since snd_usb_hw_params() doesn't touch the parameters (at least it tires so). But dropping it is still a bit risky (e.g. we have the media-driver binding), so I leave the D0 power state change in snd_usb_hw_params() as is for now.

So for regular csum/extent/fst roots, we load them into fs_info::global_root_tree rb tree. And we should not expect any conflicts in that rb tree, thus we have an ASSERT() inside btrfs_global_root_insert(). But rescue=usebackuproot can break the assumption, as we will try to load those trees again and again as long as we have bad roots and have backup roots slot remaining. So in that case we can have conflicting roots in the rb tree, and triggering the ASSERT() crash. [FIX] We can safely remove that ASSERT(), as the caller will properly put the offending root. To make further debugging easier, also add two explicit error messages: - Error message for conflicting global roots - Error message when using backup roots slot Reported-by: <syzbot+a694851c6ab28cbcfb9c@syzkaller.appspotmail.com> Fixes: abed4aaa ("btrfs: track the csum, extent, and free space trees in a rb tree") CC: stable@vger.kernel.org # 6.1+ Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
