+From: Vijendar Mukunda <Vijendar.Mukunda@amd.com>
+
+[ Upstream commit 70fa3900c3ed92158628710e81d274e5cb52f92b ]
+
+ACP supports different pin configurations for I2S IO. Checking ACP pin
+configuration value against specific value breaks the functionality for
+other I2S pin configurations. This check is no longer required in i2s dai
+driver probe call as i2s configuration check will be verified during acp
+platform device creation sequence.
+Remove i2s_mode check in acp_i2s_probe() function.

+
+From: Elinor Montmasson <elinor.montmasson@savoirfairelinux.com>
+
+[ Upstream commit 90f3feb24172185f1832636264943e8b5e289245 ]
+
+priv->pdev pointer was set after being used in
+fsl_asoc_card_audmux_init().
+Move this assignment at the start of the probe function, so
+sub-functions can correctly use pdev through priv.
+
+fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
+dev struct, used with dev_err macros.
+As priv is zero-initialised, there would be a NULL pointer dereference.
+Note that if priv->dev is dereferenced before assignment but never used,
+for example if there is no error to be printed, the driver won't crash
+probably due to compiler optimisations.

+When TRCM mode is enabled, I2S RX and TX clocks are synchronized through

+to an uninitialized MCLK and the DAI will receive data at wrong pace.
+
+However, unlike in original i2s-tdm driver, there is no need to manually

+Subject: bpf: Fix overrunning reservations in ringbuf
+
+From: Daniel Borkmann <daniel@iogearbox.net>
+
+[ Upstream commit cfa1a2329a691ffd991fcf7248a57d752e712881 ]
+
+The BPF ring buffer internally is implemented as a power-of-2 sized circular
+buffer, with two logical and ever-increasing counters: consumer_pos is the
+consumer counter to show which logical position the consumer consumed the
+data, and producer_pos which is the producer counter denoting the amount of
+data reserved by all producers.
+
+Each time a record is reserved, the producer that "owns" the record will
+successfully advance producer counter. In user space each time a record is
+read, the consumer of the data advanced the consumer counter once it finished
+processing. Both counters are stored in separate pages so that from user
+space, the producer counter is read-only and the consumer counter is read-write.
+
+One aspect that simplifies and thus speeds up the implementation of both
+producers and consumers is how the data area is mapped twice contiguously
+back-to-back in the virtual memory, allowing to not take any special measures
+for samples that have to wrap around at the end of the circular buffer data
+area, because the next page after the last data page would be first data page
+again, and thus the sample will still appear completely contiguous in virtual
+memory.
+
+Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
+book-keeping the length and offset, and is inaccessible to the BPF program.
+Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
+for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
+possible to make a second allocated memory chunk overlapping with the first
+chunk and as a result, the BPF program is now able to edit first chunk's
+header.
+
+For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
+of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
+bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
+[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
+allocate a chunk B with size 0x3000. This will succeed because consumer_pos
+was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
+check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
+to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
+earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
+pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
+bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
+locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
+B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
+page and could cause a crash.
+
+Fix it by calculating the oldest pending_pos and check whether the range
+from the oldest outstanding record to the newest would span beyond the ring
+buffer size. If that is the case, then reject the request. We've tested with
+the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
+before/after the fix and while it seems a bit slower on some benchmarks, it
+is still not significantly enough to matter.

+Subject: Fix race for duplicate reqsk on identical SYN
+
+From: luoxuanqiang <luoxuanqiang@kylinos.cn>
+
+[ Upstream commit ff46e3b4421923937b7f6e44ffcd3549a074f321 ]
+
+When bonding is configured in BOND_MODE_BROADCAST mode, if two identical
+SYN packets are received at the same time and processed on different CPUs,
+it can potentially create the same sk (sock) but two different reqsk
+(request_sock) in tcp_conn_request().
+
+These two different reqsk will respond with two SYNACK packets, and since
+the generation of the seq (ISN) incorporates a timestamp, the final two
+SYNACK packets will have different seq values.
+
+The consequence is that when the Client receives and replies with an ACK
+to the earlier SYNACK packet, we will reset(RST) it.
+
+========================================================================
+
+This behavior is consistently reproducible in my local setup,
+which comprises:
+
+ | NETA1 ------ NETB1 |
+PC_A --- bond --- | | --- bond --- PC_B
+ | NETA2 ------ NETB2 |
+
+- PC_A is the Server and has two network cards, NETA1 and NETA2. I have
+ bonded these two cards using BOND_MODE_BROADCAST mode and configured
+ them to be handled by different CPU.
+
+- PC_B is the Client, also equipped with two network cards, NETB1 and
+ NETB2, which are also bonded and configured in BOND_MODE_BROADCAST mode.
+
+If the client attempts a TCP connection to the server, it might encounter
+a failure. Capturing packets from the server side reveals:
+
+10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
+10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
+localhost > 10.10.10.10.45182: Flags [S.], seq 2967855116,
+localhost > 10.10.10.10.45182: Flags [S.], seq 2967855123, <==
+10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
+10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
+localhost > 10.10.10.10.45182: Flags [R], seq 2967855117, <==
+localhost > 10.10.10.10.45182: Flags [R], seq 2967855117,
+
+Two SYNACKs with different seq numbers are sent by localhost,
+resulting in an anomaly.
+
+========================================================================
+
+The attempted solution is as follows:
+Add a return value to inet_csk_reqsk_queue_hash_add() to confirm if the
+ehash insertion is successful (Up to now, the reason for unsuccessful
+insertion is that a reqsk for the same connection has already been
+inserted). If the insertion fails, release the reqsk.
+
+Due to the refcnt, Kuniyuki suggests also adding a return value check
+for the DCCP module; if ehash insertion fails, indicating a successful
+insertion of the same connection, simply release the reqsk as well.
+
+Simultaneously, In the reqsk_queue_hash_req(), the start of the
+req->rsk_timer is adjusted to be after successful insertion.

+Subject: ibmvnic: Free any outstanding tx skbs during scrq reset
+
+From: Nick Child <nnac123@linux.ibm.com>
+
+[ Upstream commit 49bbeb5719c2f56907d3a9623b47c6c15c2c431d ]
+
+There are 2 types of outstanding tx skb's:
+Type 1: Packets that are sitting in the drivers ind_buff that are
+waiting to be batch sent to the NIC. During a device reset, these are
+freed with a call to ibmvnic_tx_scrq_clean_buffer()
+Type 2: Packets that have been sent to the NIC and are awaiting a TX
+completion IRQ. These are free'd during a reset with a call to
+clean_tx_pools()
+
+During any reset which requires us to free the tx irq, ensure that the
+Type 2 skb references are freed. Since the irq is released, it is
+impossible for the NIC to inform of any completions.
+
+Furthermore, later in the reset process is a call to init_tx_pools()
+which marks every entry in the tx pool as free (ie not outstanding).
+So if the driver is to make a call to init_tx_pools(), it must first
+be sure that the tx pool is empty of skb references.
+
+This issue was discovered by observing the following in the logs during
+EEH testing:
+ TX free map points to untracked skb (tso_pool 0 idx=4)
+ TX free map points to untracked skb (tso_pool 0 idx=5)
+ TX free map points to untracked skb (tso_pool 1 idx=36)

+Subject: mlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems
+
+From: Ido Schimmel <idosch@nvidia.com>
+
+[ Upstream commit c28947de2bed40217cf256c5d0d16880054fcf13 ]
+
+The following two shared buffer operations make use of the Shared Buffer
+Status Register (SBSR):
+
+ # devlink sb occupancy snapshot pci/0000:01:00.0
+ # devlink sb occupancy clearmax pci/0000:01:00.0
+
+The register has two masks of 256 bits to denote on which ingress /
+egress ports the register should operate on. Spectrum-4 has more than
+256 ports, so the register was extended by cited commit with a new
+'port_page' field.
+
+However, when filling the register's payload, the driver specifies the
+ports as absolute numbers and not relative to the first port of the port
+page, resulting in memory corruptions [1].
+
+Fix by specifying the ports relative to the first port of the port page.

+
+From: Tristram Ha <tristram.ha@microchip.com>
+
+[ Upstream commit ad53f5f54f351e967128edbc431f0f26427172cf ]
+
+The very first flush in any port will flush all learned addresses in all
+ports. This can be observed by unplugging the cable from one port while
+additional ports are connected and dumping the fdb entries.
+
+This problem is caused by the initially wrong value programmed to the
+REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
+SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
+ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
+takes effect and flushes all learned entries. After that call both bits
+are reset and so the next port flush will not cause such problem again.

+Subject: net: dsa: microchip: fix wrong register write when masking interrupt
+
+From: Tristram Ha <tristram.ha@microchip.com>
+
+[ Upstream commit b1c4b4d45263241ec6c2405a8df8265d4b58e707 ]
+
+The switch global port interrupt mask, REG_SW_PORT_INT_MASK__4, is
+defined as 0x001C in ksz9477_reg.h. The designers used 32-bit value in
+anticipation for increase of port count in future product but currently
+the maximum port count is 7 and the effective value is 0x7F in register
+0x001F. Each port has its own interrupt mask and is defined as 0x#01F.
+It uses only 4 bits for different interrupts.
+
+The developer who implemented the current interrupt mechanism in the
+switch driver noticed there are similarities between the mechanism to
+mask port interrupts in global interrupt and individual interrupts in
+each port and so used the same code to handle these interrupts. He
+updated the code to use the new macro REG_SW_PORT_INT_MASK__1 which is
+defined as 0x1F in ksz_common.h but he forgot to update the 32-bit write
+to 8-bit as now the mask registers are 0x1F and 0x#01F.
+
+In addition all KSZ switches other than the KSZ9897/KSZ9893 and LAN937X
+families use only 8-bit access and so this common code will eventually
+be changed to accommodate them.

+Subject: netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data
+ registers
+
+From: Pablo Neira Ayuso <pablo@netfilter.org>
+
+[ Upstream commit 7931d32955e09d0a11b1fe0b6aac1bfa061c005c ]
+
+register store validation for NFT_DATA_VALUE is conditional, however,
+the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
+only requires a new helper function to infer the register type from the
+set datatype so this conditional check can be removed. Otherwise,
+pointer to chain object can be leaked through the registers.

+of these syscalls, so receiving cmsg messages that require a compat
+conversion is still broken.
+
+Use the correct calls like the other architectures do.

+
+[ Upstream commit d6fbd26fb872ec518d25433a12e8ce8163e20909 ]
+
+sparc has the wrong compat version of recv() and recvfrom() for both the
+direct syscalls and socketcall().
+
+The direct syscalls just need to use the compat version. For socketcall,
+the same thing could be done, but it seems better to completely remove
+the custom assembler code for it and just use the same implementation that
+everyone else has.

+Subject: sparc: fix old compat_sys_select()
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit bae6428a9fffb2023191b0723e276cf1377a7c9f ]
+
+sparc has two identical select syscalls at numbers 93 and 230, respectively.
+During the conversion to the modern syscall.tbl format, the older one of the
+two broke in compat mode, and now refers to the native 64-bit syscall.
+
+Restore the correct behavior. This has very little effect, as glibc has
+been using the newer number anyway.

+Subject: tcp: fix tcp_rcv_fastopen_synack() to enter TCP_CA_Loss for failed
+ TFO
+
+From: Neal Cardwell <ncardwell@google.com>
+
+[ Upstream commit 5dfe9d273932c647bdc9d664f939af9a5a398cbc ]
+
+Testing determined that the recent commit 9e046bb111f1 ("tcp: clear
+tp->retrans_stamp in tcp_rcv_fastopen_synack()") has a race, and does
+not always ensure retrans_stamp is 0 after a TFO payload retransmit.
+
+If transmit completion for the SYN+data skb happens after the client
+TCP stack receives the SYNACK (which sometimes happens), then
+retrans_stamp can erroneously remain non-zero for the lifetime of the
+connection, causing a premature ETIMEDOUT later.
+
+Testing and tracing showed that the buggy scenario is the following
+somewhat tricky sequence:
+
++ Client attempts a TFO handshake. tcp_send_syn_data() sends SYN + TFO
+ cookie + data in a single packet in the syn_data skb. It hands the
+ syn_data skb to tcp_transmit_skb(), which makes a clone. Crucially,
+ it then reuses the same original (non-clone) syn_data skb,
+ transforming it by advancing the seq by one byte and removing the
+ FIN bit, and enques the resulting payload-only skb in the
+ sk->tcp_rtx_queue.
+
++ Client sets retrans_stamp to the start time of the three-way
+ handshake.
+
++ Cookie mismatches or server has TFO disabled, and server only ACKs
+ SYN.
+
++ tcp_ack() sees SYN is acked, tcp_clean_rtx_queue() clears
+ retrans_stamp.
+
++ Since the client SYN was acked but not the payload, the TFO failure
+ code path in tcp_rcv_fastopen_synack() tries to retransmit the
+ payload skb. However, in some cases the transmit completion for the
+ clone of the syn_data (which had SYN + TFO cookie + data) hasn't
+ happened. In those cases, skb_still_in_host_queue() returns true
+ for the retransmitted TFO payload, because the clone of the syn_data
+ skb has not had its tx completetion.
+
++ Because skb_still_in_host_queue() finds skb_fclone_busy() is true,
+ it sets the TSQ_THROTTLED bit and the retransmit does not happen in
+ the tcp_rcv_fastopen_synack() call chain.
+
++ The tcp_rcv_fastopen_synack() code next implicitly assumes the
+ retransmit process is finished, and sets retrans_stamp to 0 to clear
+ it, but this is later overwritten (see below).
+
++ Later, upon tx completion, tcp_tsq_write() calls
+ tcp_xmit_retransmit_queue(), which puts the retransmit in flight and
+ sets retrans_stamp to a non-zero value.
+
++ The client receives an ACK for the retransmitted TFO payload data.
+
++ Since we're in CA_Open and there are no dupacks/SACKs/DSACKs/ECN to
+ make tcp_ack_is_dubious() true and make us call
+ tcp_fastretrans_alert() and reach a code path that clears
+ retrans_stamp, retrans_stamp stays nonzero.
+
++ Later, if there is a TLP, RTO, RTO sequence, then the connection
+ will suffer an early ETIMEDOUT due to the erroneously ancient
+ retrans_stamp.
+
+The fix: this commit refactors the code to have
+tcp_rcv_fastopen_synack() retransmit by reusing the relevant parts of
+tcp_simple_retransmit() that enter CA_Loss (without changing cwnd) and
+call tcp_xmit_retransmit_queue(). We have tcp_simple_retransmit() and
+tcp_rcv_fastopen_synack() share code in this way because in both cases
+we get a packet indicating non-congestion loss (MTU reduction or TFO
+failure) and thus in both cases we want to retransmit as many packets
+as cwnd allows, without reducing cwnd. And given that retransmits will
+set retrans_stamp to a non-zero value (and may do so in a later
+calling context due to TSQ), we also want to enter CA_Loss so that we
+track when all retransmitted packets are ACked and clear retrans_stamp
+when that happens (to ensure later recurring RTOs are using the
+correct retrans_stamp and don't declare ETIMEDOUT prematurely).
+
+Fixes: 9e046bb111f1 ("tcp: clear tp->retrans_stamp in tcp_rcv_fastopen_synack()")
+Fixes: a7abf3cd76e1 ("tcp: consider using standard rtx logic in tcp_rcv_fastopen_synack()")

+ perf_trace_qdisc_reset()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Yunseong Kim <yskelg@gmail.com>
+
+[ Upstream commit bab4923132feb3e439ae45962979c5d9d5c7c1f1 ]
+
+In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from
+
+ qdisc->dev_queue->dev <NULL> ->name
+
+This situation simulated from bunch of veths and Bluetooth disconnection
+and reconnection.
+
+During qdisc initialization, qdisc was being set to noop_queue.
+In veth_init_queue, the initial tx_num was reduced back to one,
+causing the qdisc reset to be called with noop, which led to the kernel
+panic.
+
+I've attached the GitHub gist link that C converted syz-execprogram
+source code and 3 log of reproduced vmcore-dmesg.
+
+ https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740
+
+Yeoreum and I use two fuzzing tool simultaneously.
+
+One process with syz-executor : https://github.com/google/syzkaller
+
+ $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
+ -enable=none -collide=false log1
+
+The other process with perf fuzzer:
+ https://github.com/deater/perf_event_tests/tree/master/fuzzer
+
+ $ perf_event_tests/fuzzer/perf_fuzzer
+
+I think this will happen on the kernel version.
+
+ Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.
+
+This occurred from 51270d573a8d. I think this patch is absolutely
+necessary. Previously, It was showing not intended string value of name.
+
+I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
+or patched.

+Yeoreum and I don't know if the patch we wrote will fix the underlying
+cause, but we think that priority is to prevent kernel panic happening.
+So, we're sending this patch.

+Subject: xdp: Remove WARN() from __xdp_reg_mem_model()
+
+From: Daniil Dulov <d.dulov@aladdin.ru>
+
+[ Upstream commit 7e9f79428372c6eab92271390851be34ab26bfb4 ]
+
+syzkaller reports a warning in __xdp_reg_mem_model().
+
+The warning occurs only if __mem_id_init_hash_table() returns an error. It
+returns the error in two cases:
+
+ 1. memory allocation fails;
+ 2. rhashtable_init() fails when some fields of rhashtable_params
+ struct are not initialized properly.
+
+The second case cannot happen since there is a static const rhashtable_params
+struct with valid fields. So, warning is only triggered when there is a
+problem with memory allocation.
+
+Thus, there is no sense in using WARN() to handle this error and it can be
+safely removed.
