2025-03-07firmware: cs_dsp: Remove async regmap writesRichard Fitzgerald
[ Upstream commit fe08b7d5085a9774abc30c26d5aebc5b9cdd6091 ] Change calls to async regmap write functions to use the normal blocking writes so that the cs35l56 driver can use spi_bus_lock() to gain exclusive access to the SPI bus. As this is part of a fix, it makes only the minimal change to swap the functions to the blocking equivalents. There's no need to risk reworking the buffer allocation logic that is now partially redundant. The async writes are a 12-year-old workaround for inefficiency of synchronous writes in the SPI subsystem. The SPI subsystem has since been changed to avoid the overheads, so this workaround should not be necessary. The cs35l56 driver needs to use spi_bus_lock() prevent bus activity while it is soft-resetting the cs35l56. But spi_bus_lock() is incompatible with spi_async() calls, which will fail with -EBUSY.

[ Upstream commit de2c211868b9424f9aa9b3432c4430825bafb41b ] We found an issue when using bpf_redirect with ipvs NAT mode after commit ff70202b2d1a ("dev_forward_skb: do not scrub skb mark within the same name space").

2025-03-07ASoC: es8328: fix route from DAC to outputNicolas Frattaroli
[ Upstream commit 5b0c02f9b8acf2a791e531bbc09acae2d51f4f9b ] The ES8328 codec driver, which is also used for the ES8388 chip that appears to have an identical register map, claims that the output can either take the route from DAC->Mixer->Output or through DAC->Output directly. To the best of what I could find, this is not true, and creates problems. Without DACCONTROL17 bit index 7 set for the left channel, as well as DACCONTROL20 bit index 7 set for the right channel, I cannot get any analog audio out on Left Out 2 and Right Out 2 respectively, despite the DAPM routes claiming that this should be possible. Furthermore, the same is the case for Left Out 1 and Right Out 1, showing that those two don't have a direct route from DAC to output bypassing the mixer either. Those control bits toggle whether the DACs are fed (stale bread?) into their respective mixers. If one "unmutes" the mixer controls in alsamixer, then sure, the audio output works, but if it doesn't work without the mixer being fed the DAC input then evidently it's not a direct output from the DAC. ES8328/ES8388 are seemingly not alone in this. ES8323, which uses a separate driver for what appears to be a very similar register map, simply flips those two bits on in its probe function, and then pretends there is no power management whatsoever for the individual controls. Fair enough. My theory as to why nobody has noticed this up to this point is that everyone just assumes it's their fault when they had to unmute an additional control in ALSA. Fix this in the es8328 driver by removing the erroneous direct route, then get rid of the playback switch controls and have those bits tied to the mixer's widget instead, which until now had no register to play with.

2025-03-07net: loopback: Avoid sending IP packets without an Ethernet headerIdo Schimmel
[ Upstream commit 0e4427f8f587c4b603475468bb3aee9418574893 ] After commit 22600596b675 ("ipv4: give an IPv4 dev to blackhole_netdev") IPv4 neighbors can be constructed on the blackhole net device, but they are constructed with an output function (neigh_direct_output()) that simply calls dev_queue_xmit(). The latter will transmit packets via 'skb->dev' which might not be the blackhole net device if dst_dev_put() switched 'dst->dev' to the blackhole net device while another CPU was using the dst entry in ip_output(), but after it already initialized 'skb->dev' from 'dst->dev'. Specifically, the following can happen: CPU1 CPU2 udp_sendmsg(sk1) udp_sendmsg(sk2) udp_send_skb() [...] ip_output() skb->dev = skb_dst(skb)->dev dst_dev_put() dst->dev = blackhole_netdev ip_finish_output2() resolves neigh on dst->dev neigh_output() neigh_direct_output() dev_queue_xmit() This will result in IPv4 packets being sent without an Ethernet header via a valid net device: tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on enp9s0, link-type EN10MB (Ethernet), snapshot length 262144 bytes 22:07:02.329668 20:00:40:11:18:fb > 45:00:00:44:f4:94, ethertype Unknown (0x58c6), length 68: 0x0000: 8dda 74ca f1ae ca6c ca6c 0098 969c 0400 ..t....l.l...... 0x0010: 0000 4730 3f18 6800 0000 0000 0000 9971 ..G0?.h........q 0x0020: c4c9 9055 a157 0a70 9ead bf83 38ca ab38 ...U.W.p....8..8 0x0030: 8add ab96 e052 .....R Fix by making sure that neighbors are constructed on top of the blackhole net device with an output function that simply consumes the packets, in a similar fashion to dst_discard_out() and blackhole_netdev_xmit().

[ Upstream commit 1f0fc3374f3345ff1d150c5c56ac5016e5d3826a ] Give an afs_server object a ref on the afs_cell object it points to so that the cell doesn't get deleted before the server record. Whilst this is circular (cell -> vol -> server_list -> server -> cell), the ref only pins the memory, not the lifetime as that's controlled by the activity counter. When the volume's activity counter reaches 0, it detaches from the cell and discards its server list; when a cell's activity counter reaches 0, it discards its root volume. At that point, the circularity is cut.

2025-03-07afs: Fix the server_list to unuse a displaced server rather than putting itDavid Howells
[ Upstream commit add117e48df4788a86a21bd0515833c0a6db1ad1 ] When allocating and building an afs_server_list struct object from a VLDB record, we look up each server address to get the server record for it - but a server may have more than one entry in the record and we discard the duplicate pointers. Currently, however, when we discard, we only put a server record, not unuse it - but the lookup got as an active-user count. The active-user count on an afs_server_list object determines its lifetime whereas the refcount keeps the memory backing it around. Failing to reduce the active-user counter prevents the record from being cleaned up and can lead to multiple copied being seen - and pointing to deleted afs_cell objects and other such things. Fix this by switching the incorrect 'put' to an 'unuse' instead. Without this, occasionally, a dead server record can be seen in /proc/net/afs/servers and list corruption may be observed: list_del corruption. prev->next should be ffff888102423e40, but was 0000000000000000.

[ Upstream commit a3bdd8f5c2217e1cb35db02c2eed36ea20fb50f5 ] We fixed the UAF issue in USB MIDI code by canceling the pending work at closing each MIDI output device in the commit below. However, this assumed that it's the only one that is tied with the endpoint, and it resulted in unexpected data truncations when multiple devices are assigned to a single endpoint and opened simultaneously. For addressing the unexpected MIDI message drops, simply replace cancel_work_sync() with flush_work(). The drain callback should have been already invoked before the close callback, hence the port->active flag must be already cleared. So this just assures that the pending work is finished before freeing the resources.

2025-03-07landlock: Fix non-TCP sockets restrictionMikhail Ivanov
[ Upstream commit 854277e2cc8c75dc3c216c82e72523258fcf65b9 ] Use sk_is_tcp() to check if socket is TCP in bind(2) and connect(2) hooks. SMC, MPTCP, SCTP protocols are currently restricted by TCP access rights. The purpose of TCP access rights is to provide control over ports that can be used by userland to establish a TCP connection. Therefore, it is incorrect to deny bind(2) and connect(2) requests for a socket of another protocol. However, SMC, MPTCP and RDS implementations use TCP internal sockets to establish communication or even to exchange packets over a TCP connection [1]. Landlock rules that configure bind(2) and connect(2) usage for TCP sockets should not cover requests for sockets of such protocols. These protocols have different set of security issues and security properties, therefore, it is necessary to provide the userland with the ability to distinguish between them (eg. [2]). Control over TCP connection used by other protocols can be achieved with upcoming support of socket creation control [3].

[ Upstream commit 9747c0c7791d4a5a62018a0c9c563dd2e6f6c1c0 ] If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

2025-03-07RDMA/mlx5: Fix a race for DMABUF MR which can lead to CQE with errorYishai Hadas
[ Upstream commit cc668a11e6ac8adb0e016711080d3f314722cc91 ] This patch addresses a potential race condition for a DMABUF MR that can result in a CQE with an error on the UMR QP. During the __mlx5_ib_dereg_mr() flow, the following sequence of calls occurs: mlx5_revoke_mr() mlx5r_umr_revoke_mr() mlx5r_umr_post_send_wait() At this point, the lkey is freed from the hardware's perspective. However, concurrently, mlx5_ib_dmabuf_invalidate_cb() might be triggered by another task attempting to invalidate the MR having that freed lkey. Since the lkey has already been freed, this can lead to a CQE error, causing the UMR QP to enter an error state. To resolve this race condition, the dma_resv_lock() which was hold as part of the mlx5_ib_dmabuf_invalidate_cb() is now also acquired as part of the mlx5_revoke_mr() scope. Upon a successful revoke, we set umem_dmabuf->private which points to that MR to NULL, preventing any further invalidation attempts on its lkey.

2025-03-07RDMA/mlx5: Fix the recovery flow of the UMR QPYishai Hadas
[ Upstream commit d97505baea64d93538b16baf14ce7b8c1fbad746 ] This patch addresses an issue in the recovery flow of the UMR QP, ensuring tasks do not get stuck, as highlighted by the call trace [1]. During recovery, before transitioning the QP to the RESET state, the software must wait for all outstanding WRs to complete. Failing to do so can cause the firmware to skip sending some flushed CQEs with errors and simply discard them upon the RESET, as per the IB specification. This race condition can result in lost CQEs and tasks becoming stuck. To resolve this, the patch sends a final WR which serves only as a barrier before moving the QP state to RESET. Once a CQE is received for that final WR, it guarantees that no outstanding WRs remain, making it safe to transition the QP to RESET and subsequently back to RTS, restoring proper functionality. Note: For the barrier WR, we simply reuse the failed and ready WR. Since the QP is in an error state, it will only receive IB_WC_WR_FLUSH_ERR. However, as it serves only as a barrier we don't care about its status. [1] INFO: task rdma_resource_l:1922 blocked for more than 120 seconds.
