+Subject: clk: imx: pll14xx: dynamically configure PLL for
+ 393216000/361267200Hz
+
+From: Ahmad Fatoum <a.fatoum@pengutronix.de>
+
+[ Upstream commit 72d00e560d10665e6139c9431956a87ded6e9880 ]
+
+Since commit b09c68dc57c9 ("clk: imx: pll14xx: Support dynamic rates"),
+the driver has the ability to dynamically compute PLL parameters to
+approximate the requested rates. This is not always used, because the
+logic is as follows:
+
+ - Check if the target rate is hardcoded in the frequency table
+ - Check if varying only kdiv is possible, so switch over is glitch free
+ - Compute rate dynamically by iterating over pdiv range
+
+If we skip the frequency table for the 1443x PLL, we find that the
+computed values differ to the hardcoded ones. This can be valid if the
+hardcoded values guarantee for example an earlier lock-in or if the
+divisors are chosen, so that other important rates are more likely to
+be reached glitch-free.
+
+For rates (393216000 and 361267200, this doesn't seem to be the case:
+They are only approximated by existing parameters (393215995 and
+361267196 Hz, respectively) and they aren't reachable glitch-free from
+other hardcoded frequencies. Dropping them from the table allows us
+to lock-in to these frequencies exactly.
+
+This is immediately noticeable because they are the assigned-clock-rates
+for IMX8MN_AUDIO_PLL1 and IMX8MN_AUDIO_PLL2, respectively and a look
+into clk_summary so far showed that they were a few Hz short of the target:
+
+imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
+audio_pll2_out 0 0 0 361267196 0 0 50000 N
+audio_pll1_out 1 1 0 393215995 0 0 50000 Y
+
+and afterwards:
+
+imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
+audio_pll2_out 0 0 0 361267200 0 0 50000 N
+audio_pll1_out 1 1 0 393216000 0 0 50000 Y
+
+This change is equivalent to adding following hardcoded values:
+
+ /* rate mdiv pdiv sdiv kdiv */
+ PLL_1443X_RATE(393216000, 655, 5, 3, 23593),
+ PLL_1443X_RATE(361267200, 497, 33, 0, -16882),

+Subject: clk: imx8mm: Move 1443X/1416X PLL clock structure to common place
+
+From: Anson Huang <Anson.Huang@nxp.com>
+
+[ Upstream commit 43cdaa1567ad3931fbde438853947d45238cc040 ]
+
+Many i.MX8M SoCs use same 1443X/1416X PLL, such as i.MX8MM,
+i.MX8MN and later i.MX8M SoCs, moving these PLL definitions
+to pll14xx driver can save a lot of duplicated code on each
+platform.
+
+Meanwhile, no need to define PLL clock structure for every
+module which uses same type of PLL, e.g., audio/video/dram use
+1443X PLL, arm/gpu/vpu/sys use 1416X PLL, define 2 PLL clock
+structure for each group is enough.

+Subject: ixgbe: fix timestamp configuration code
+
+From: Vadim Fedorenko <vadim.fedorenko@linux.dev>
+
+[ Upstream commit 3c44191dd76cf9c0cc49adaf34384cbd42ef8ad2 ]
+
+The commit in fixes introduced flags to control the status of hardware
+configuration while processing packets. At the same time another structure
+is used to provide configuration of timestamper to user-space applications.
+The way it was coded makes this structures go out of sync easily. The
+repro is easy for 82599 chips:
+
+[root@hostname ~]# hwstamp_ctl -i eth0 -r 12 -t 1
+current settings:
+tx_type 0
+rx_filter 0
+new settings:
+tx_type 1
+rx_filter 12
+
+The eth0 device is properly configured to timestamp any PTPv2 events.
+
+[root@hostname ~]# hwstamp_ctl -i eth0 -r 1 -t 1
+current settings:
+tx_type 1
+rx_filter 12
+SIOCSHWTSTAMP failed: Numerical result out of range
+The requested time stamping mode is not supported by the hardware.
+
+The error is properly returned because HW doesn't support all packets
+timestamping. But the adapter->flags is cleared of timestamp flags
+even though no HW configuration was done. From that point no RX timestamps
+are received by user-space application. But configuration shows good
+values:
+
+[root@hostname ~]# hwstamp_ctl -i eth0
+current settings:
+tx_type 1
+rx_filter 12
+
+Fix the issue by applying new flags only when the HW was actually
+configured.

+Subject: kcm: Fix error handling for SOCK_DGRAM in kcm_sendmsg().
+
+From: Kuniyuki Iwashima <kuniyu@amazon.com>
+
+[ Upstream commit a22730b1b4bf437c6bbfdeff5feddf54be4aeada ]
+
+syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88bd720
+("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it by
+updating kcm_tx_msg(head)->last_skb if partial data is copied so that the
+following sendmsg() will resume from the skb.
+
+However, we cannot know how many bytes were copied when we get the error.
+Thus, we could mess up the MSG_MORE queue.
+
+When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as we
+do so for UDP by udp_flush_pending_frames().
+
+Even without this change, when the error occurred, the following sendmsg()
+resumed from a wrong skb and the queue was messed up. However, we have
+yet to get such a report, and only syzkaller stumbled on it. So, this
+can be changed safely.
+
+Note this does not change SOCK_SEQPACKET behaviour.

+In kcm_sendmsg(), kcm_tx_msg(head)->last_skb is used as a cursor to append
+newly allocated skbs to 'head'. If some bytes are copied, an error occurred,
+and jumped to out_error label, 'last_skb' is left unmodified. A later
+kcm_sendmsg() will use an obsoleted 'last_skb' reference, corrupting the
+'head' frag_list and causing the leak.
+
+This patch fixes this issue by properly updating the last allocated skb in
+'last_skb'.

+Subject: mlxbf-tmfifo: sparse tags for config access
+
+From: Michael S. Tsirkin <mst@redhat.com>
+
+[ Upstream commit 03bea764bf61c9f9918324bda7362616024386e8 ]
+
+mlxbf-tmfifo accesses config space using native types -
+which works for it since the legacy virtio native types.
+
+This will break if it ever needs to support modern virtio,
+so with new tags previously introduced for virtio net config,
+sparse now warns for this in drivers.
+
+Since this is a legacy only device, fix it up using
+virtio_legacy_is_little_endian for now.
+
+No functional changes.

+From: Hangyu Hua <hbh25y@gmail.com>

+
+rules is allocated in ethtool_get_rxnfc and the size is determined by
+rule_cnt from user space. So rule_cnt needs to be check before using
+rules to avoid OOB writing or NULL pointer dereference.

+Subject: net: ipv4: fix one memleak in __inet_del_ifa()
+
+From: Liu Jian <liujian56@huawei.com>
+
+[ Upstream commit ac28b1ec6135649b5d78b028e47264cb3ebca5ea ]
+
+I got the below warning when do fuzzing test:
+unregister_netdevice: waiting for bond0 to become free. Usage count = 2
+
+It can be repoduced via:
+
+ip link add bond0 type bond
+sysctl -w net.ipv4.conf.bond0.promote_secondaries=1
+ip addr add 4.117.174.103/0 scope 0x40 dev bond0
+ip addr add 192.168.100.111/255.255.255.254 scope 0 dev bond0
+ip addr add 0.0.0.4/0 scope 0x40 secondary dev bond0
+ip addr del 4.117.174.103/0 scope 0x40 dev bond0
+ip link delete bond0 type bond
+
+In this reproduction test case, an incorrect 'last_prim' is found in
+__inet_del_ifa(), as a result, the secondary address(0.0.0.4/0 scope 0x40)
+is lost. The memory of the secondary address is leaked and the reference of
+in_device and net_device is leaked.
+
+Fix this problem:
+Look for 'last_prim' starting at location of the deleted IP and inserting
+the promoted IP into the location of 'last_prim'.

+
+This is because the value of rec_seq of tls_crypto_info configured by the
+user program is too large, for example, 0xffffffffffffff. In addition, TLS
+is asynchronously accelerated. When tls_do_encryption() returns
+-EINPROGRESS and sk->sk_err is set to EBADMSG due to rec_seq overflow,
+skmsg is released before the asynchronous encryption process ends. As a
+result, the UAF problem occurs during the asynchronous processing of the
+encryption module.
+
+If the operation is asynchronous and the encryption module returns
+EINPROGRESS, do not free the record information.

+
+From: Liming Sun <limings@nvidia.com>
+
+[ Upstream commit 78034cbece79c2d730ad0770b3b7f23eedbbecf5 ]
+
+This commit fixes tmfifo console stuck issue when the virtual
+networking interface is in down state. In such case, the network
+Rx descriptors runs out and causes the Rx network packet staying
+in the head of the tmfifo thus blocking the console packets. The
+fix is to drop the Rx network packet when no more Rx descriptors.
+Function name mlxbf_tmfifo_release_pending_pkt() is also renamed
+to mlxbf_tmfifo_release_pkt() to be more approperiate.

+Subject: r8152: check budget for r8152_poll()
+
+From: Hayes Wang <hayeswang@realtek.com>
+
+[ Upstream commit a7b8d60b37237680009dd0b025fe8c067aba0ee3 ]
+
+According to the document of napi, there is no rx process when the
+budget is 0. Therefore, r8152_poll() has to return 0 directly when the
+budget is equal to 0.

+Subject: usb: typec: bus: verify partner exists in typec_altmode_attention
+
+From: RD Babiera <rdbabiera@google.com>
+
+[ Upstream commit f23643306430f86e2f413ee2b986e0773e79da31 ]
+
+Some usb hubs will negotiate DisplayPort Alt mode with the device
+but will then negotiate a data role swap after entering the alt
+mode. The data role swap causes the device to unregister all alt
+modes, however the usb hub will still send Attention messages
+even after failing to reregister the Alt Mode. type_altmode_attention
+currently does not verify whether or not a device's altmode partner
+exists, which results in a NULL pointer error when dereferencing
+the typec_altmode and typec_altmode_ops belonging to the altmode
+partner.
+
+Verify the presence of a device's altmode partner before sending
+the Attention message to the Alt Mode driver.

+
+[ Upstream commit 8afe9a3548f9d1805dcea6d97978f2179c8403a3 ]
+
+Refactor the tcpm_handle_vdm_request payload handling by doing the

+itself instead of doing it multiple times inside various helper functions
+called by tcpm_handle_vdm_request.

+Refactor tcpm_handle_vdm_request and its tcpm_pd_svdm helper function so
