Formally decouple the two steps, ensuring that mptcp explicitly closes all the subflows after the mentioned helper. This will make the upcoming fix simpler, and allows dropping the 2nd argument from mptcp_destroy_common(). The Fixes tag is then the same as in the next commit to help with the backports.

The root cause is a duplicate reset, not carrying the relevant MPTCP option. In the failing scenario the bad reset is received by the peer before the fastclose one, preventing the reception of the latter. Indeed there is window of opportunity at fastclose time for the following race: mptcp_do_fastclose __mptcp_close_ssk __tcp_close() tcp_set_state() [1] tcp_send_active_reset() [2] After [1] the stack will send reset to in-flight data reaching the now closed port.

[PATCH v3 1/2] drm/xe/uapi: disallow bind queue sharing

by Matthew Auld

Currently this is very broken if someone attempts to create a bind queue and share it across multiple VMs. For example currently we assume it is safe to acquire the user VM lock to protect some of the bind queue state, but if allow sharing the bind queue with multiple VMs then this quickly breaks down. To fix this reject using a bind queue with any VM that is not the same VM that was originally passed when creating the bind queue. This a uAPI change, however this was more of an oversight on kernel side that we didn't reject this, and expectation is that userspace shouldn't be using bind queues in this way, so in theory this change should go unnoticed. Based on a patch from Matt Brost. v2 (Matt B): - Hold the vm lock over queue create, to ensure it can't be closed as we attach the user_vm to the queue. - Make sure we actually check for NULL user_vm in destruction path. v3: - Fix error path handling.

[PATCH] drm: sti: fix device leaks at component probe

by Johan Hovold

Make sure to drop the references taken to the vtg devices by of_find_device_by_node() when looking up their driver data during component probe. Note that holding a reference to a platform device does not prevent its driver data from going away so there is no point in keeping the reference after the lookup helper returns.

However the inline assembly is written incorrectly: for such cases a zero is loaded into a register allocated by the compiler and this register is then used by the instruction. This means that selected TLB entries may not be flushed since the specified ASCE does not match the one which was used when the selected TLB entries were created. Fix this by removing the asce and opt parameters of __ptep_rdp(), since all callers always pass zero, and use a hard-coded register zero for the R3 field.

''' tcp_rcv_state_process() subflow_syn_recv_sock() tcp_init_transfer(BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB) bpf_skops_established <== sockops bpf_sock_map_update(sk) <== call bpf helper tcp_bpf_update_proto() <== update sk_prot ''' Consider two scenarios: 1. When the server has MPTCP enabled and the client also requests MPTCP, the sk passed to the BPF program is a subflow sk. Since subflows only handle partial data, replacing their sk_prot is meaningless and will cause traffic disruption. 2. When the server has MPTCP enabled but the client sends a TCP SYN without MPTCP, subflow_syn_recv_sock() performs a fallback on the subflow, replacing the subflow sk's sk_prot with the native sk_prot. ''' subflow_ulp_fallback() subflow_drop_ctx() mptcp_subflow_ops_undo_override() ''' Subsequently, accept::mptcp_stream_accept::mptcp_fallback_tcp_ops() converts the subflow to plain TCP. For the first case, we should prevent it from being combined with sockmap by setting sk_prot->psock_update_sk_prot to NULL, which will be blocked by sockmap's own flow. For the second case, since subflow_syn_recv_sock() has already restored sk_prot to native tcp_prot/tcpv6_prot, no further action is needed.

WTF: patch "[PATCH] block: add __must_check attribute to sb_min_blocksize()" was seriously submitted to be applied to the 6.15-stable tree?

After commit a64e5a596067bd ("bdev: add back PAGE_SIZE block size validation for sb_set_blocksize()"), this becomes more likely to happen when the block device’s logical_block_size is larger than PAGE_SIZE and the filesystem is unformatted.

[PATCH] media: venus: vdec: restrict EOS addr quirk to IRIS2 only

by Dikshita Agarwal

On SM8250 (IRIS2) with firmware older than 1.0.087, the firmware could not handle a dummy device address for EOS buffers, so a NULL device address is sent instead. The existing check used IS_V6() alongside a firmware version gate: if (IS_V6(core) && is_fw_rev_or_older(core, 1, 0, 87)) fdata.device_addr = 0; else fdata.device_addr = 0xdeadb000; However, SC7280 which is also V6, uses a firmware string of the form "1.0.<commit-hash>", which the version parser translates to 1.0.0. This unintentionally satisfies the `is_fw_rev_or_older(..., 1, 0, 87)` condition on SC7280. Combined with IS_V6() matching there as well, the quirk is incorrectly applied to SC7280, causing VP9 decode failures. Constrain the check to IRIS2 (SM8250) only, which is the only platform that needed this quirk, by replacing IS_V6() with IS_IRIS2(). This restores correct behavior on SC7280 (no forced NULL EOS buffer address).

[PATCH v4] w1: therm: Fix off-by-one buffer overflow in alarms_store

by Thorsten Blum

The sysfs buffer passed to alarms_store() is allocated with 'size + 1' bytes and a NUL terminator is appended. However, the 'size' argument does not account for this extra byte. The original code then allocated 'size' bytes and used strcpy() to copy 'buf', which always writes one byte past the allocated buffer since strcpy() copies until the NUL terminator at index 'size'. Fix this by parsing the 'buf' parameter directly using simple_strtoll() without allocating any intermediate memory or string copying. This removes the overflow while simplifying the code. Cc: stable(a)vger.kernel.org Fixes: e2c94d6f5720 ("w1_therm: adding alarm sysfs entry") Signed-off-by: Thorsten Blum <thorsten.blum(a)linux.dev> --- Compile-tested only.

[PATCH 3/4] ASoC: stm32: sai: fix OF node leak on probe

by Johan Hovold

The reference taken to the sync provider OF node when probing the platform device is currently only dropped if the set_sync() callback fails during DAI probe. Make sure to drop the reference on platform probe failures (e.g. probe deferral) and on driver unbind. This also avoids a potential use-after-free in case the DAI is ever reprobed without first rebinding the platform driver.

Make sure to drop the reference taken when looking up the sync provider device and its driver data during DAI probe on probe failures and on unbind.
