2024-10-13parport: Proper fix for array out-of-bounds accessTakashi Iwai
The recent fix for array out-of-bounds accesses replaced sprintf() calls blindly with snprintf(). However, since snprintf() returns the would-be-printed size, not the actually output size, the length calculation can still go over the given limit. Use scnprintf() instead of snprintf(), which returns the actually output letters, for addressing the potential out-of-bounds access properly.

2024-10-12pinctrl: ocelot: fix system hang on level based interruptsSergey Matsievskiy
The current implementation only calls chained_irq_enter() and chained_irq_exit() if it detects pending interrupts. ``` for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, &reg); if (!reg) continue; chained_irq_enter(parent_chip, desc); ``` However, in case of GPIO pin configured in level mode and the parent controller configured in edge mode, GPIO interrupt might be lowered by the hardware. In the result, if the interrupt is short enough, the parent interrupt is still pending while the GPIO interrupt is cleared; chained_irq_enter() never gets called and the system hangs trying to service the parent interrupt. Moving chained_irq_enter() and chained_irq_exit() outside the for loop ensures that they are called even when GPIO interrupt is lowered by the hardware. The similar code with chained_irq_enter() / chained_irq_exit() functions wrapping interrupt checking loop may be found in many other drivers: ``` grep -r -A 10 chained_irq_enter drivers/pinctrl ``` Cc: stable@vger.kernel.org Signed-off-by: Sergey Matsievskiy <matsievskiysv@gmail.com> Reviewed-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Link: https://lore.kernel.org/20241012105743.12450-2-matsievskiysv@gmail.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2024-10-11RDMA/bnxt_re: Fix the GID table lengthKalesh AP
GID table length is reported by FW. The gid index which is passed to the driver during modify_qp/create_ah is restricted by the sgid_index field of struct ib_global_route. sgid_index is u8 and the max sgid possible is 256. Each GID entry in HW will have 2 GID entries in the kernel gid table. So we can support twice the gid table size reported by FW. Also, restrict the max GID to 256 also.

2024-10-11RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loopSelvin Xavier
Driver waits indefinitely for the fifo occupancy to go below a threshold as soon as the pacing interrupt is received. This can cause soft lockup on one of the processors, if the rate of DB is very high. Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th if the loop is taking more time. Pacing will be continuing until the occupancy is below the threshold. This is ensured by the checks in bnxt_re_pacing_timer_exp and further scheduling the work for pacing based on the fifo occupancy.

2024-10-11net: enetc: disable NAPI after all rings are disabledWei Fang
When running "xdp-bench tx eno0" to test the XDP_TX feature of ENETC on LS1028A, it was found that if the command was re-run multiple times, Rx could not receive the frames, and the result of xdp-bench showed that the rx rate was 0. root@ls1028ardb:~# ./xdp-bench tx eno0 Hairpinning (XDP_TX) packets on eno0 (ifindex 3; driver fsl_enetc) Summary 2046 rx/s 0 err,drop/s Summary 0 rx/s 0 err,drop/s Summary 0 rx/s 0 err,drop/s Summary 0 rx/s 0 err,drop/s By observing the Rx PIR and CIR registers, CIR is always 0x7FF and PIR is always 0x7FE, which means that the Rx ring is full and can no longer accommodate other Rx frames. Therefore, the problem is caused by the Rx BD ring not being cleaned up. Further analysis of the code revealed that the Rx BD ring will only be cleaned if the "cleaned_cnt > xdp_tx_in_flight" condition is met. Therefore, some debug logs were added to the driver and the current values of cleaned_cnt and xdp_tx_in_flight were printed when the Rx BD ring was full. The logs are as follows. [ 178.762419] [XDP TX] >> cleaned_cnt:1728, xdp_tx_in_flight:2140 [ 178.771387] [XDP TX] >> cleaned_cnt:1941, xdp_tx_in_flight:2110 [ 178.776058] [XDP TX] >> cleaned_cnt:1792, xdp_tx_in_flight:2110 From the results, the max value of xdp_tx_in_flight has reached 2140. However, the size of the Rx BD ring is only 2048. So xdp_tx_in_flight did not drop to 0 after enetc_stop() is called and the driver does not clear it. The root cause is that NAPI is disabled too aggressively, without having waited for the pending XDP_TX frames to be transmitted, and their buffers recycled, so that xdp_tx_in_flight cannot naturally drop to 0. Later, enetc_free_tx_ring() does free those stale, unsent XDP_TX packets, but it is not coded up to also reset xdp_tx_in_flight, hence the manifestation of the bug. One option would be to cover this extra condition in enetc_free_tx_ring(), but now that the ENETC_TX_DOWN exists, we have created a window at the beginning of enetc_stop() where NAPI can still be scheduled, but any concurrent enqueue will be blocked. Therefore, enetc_wait_bdrs() and enetc_disable_tx_bdrs() can be called with NAPI still scheduled, and it is guaranteed that this will not wait indefinitely, but instead give us an indication that the pending TX frames have orderly dropped to zero. Only then should we call napi_disable(). This way, enetc_free_tx_ring() becomes entirely redundant and can be dropped as part of subsequent cleanup. The change also refactors enetc_start() so that it looks like the mirror opposite procedure of enetc_stop().

2024-10-11net: enetc: disable Tx BD rings after they are emptyWei Fang
The Tx BD rings are disabled first in enetc_stop() and the driver waits for them to become empty. This operation is not safe while the ring is actively transmitting frames, and will cause the ring to not be empty and hardware exception. As described in the NETC block guide, software should only disable an active Tx ring after all pending ring entries have been consumed (i.e. when PI = CI). Disabling a transmit ring that is actively processing BDs risks a HW-SW race hazard whereby a hardware resource becomes assigned to work on one or more ring entries only to have those entries be removed due to the ring becoming disabled. When testing XDP_REDIRECT feautre, although all frames were blocked from being put into Tx rings during ring reconfiguration, the similar warning log was still encountered: fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #6 clear fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #7 clear The reason is that when there are still unsent frames in the Tx ring, disabling the Tx ring causes the remaining frames to be unable to be sent out. And the Tx ring cannot be restored, which means that even if the xdp program is uninstalled, the Tx frames cannot be sent out anymore. Therefore, correct the operation order in enect_start() and enect_stop().

2024-10-11net: enetc: block concurrent XDP transmissions during ring reconfigurationWei Fang
When testing the XDP_REDIRECT function on the LS1028A platform, we found a very reproducible issue that the Tx frames can no longer be sent out even if XDP_REDIRECT is turned off. Specifically, if there is a lot of traffic on Rx direction, when XDP_REDIRECT is turned on, the console may display some warnings like "timeout for tx ring #6 clear", and all redirected frames will be dropped, the detailed log is as follows. root@ls1028ardb:~# ./xdp-bench redirect eno0 eno2 Redirecting from eno0 (ifindex 3; driver fsl_enetc) to eno2 (ifindex 4; driver fsl_enetc) [203.849809] fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #5 clear [204.006051] fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #6 clear [204.161944] fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #7 clear eno0->eno2 1420505 rx/s 1420590 err,drop/s 0 xmit/s xmit eno0->eno2 0 xmit/s 1420590 drop/s 0 drv_err/s 15.71 bulk-avg eno0->eno2 1420484 rx/s 1420485 err,drop/s 0 xmit/s xmit eno0->eno2 0 xmit/s 1420485 drop/s 0 drv_err/s 15.71 bulk-avg By analyzing the XDP_REDIRECT implementation of enetc driver, the driver will reconfigure Tx and Rx BD rings when a bpf program is installed or uninstalled, but there is no mechanisms to block the redirected frames when enetc driver reconfigures rings. Similarly, XDP_TX verdicts on received frames can also lead to frames being enqueued in the Tx rings. Because XDP ignores the state set by the netif_tx_wake_queue() API, so introduce the ENETC_TX_DOWN flag to suppress transmission of XDP frames.

The xdp_drops statistic indicates the number of XDP frames dropped in the Rx direction. However, enetc_xdp_drop() is also used in XDP_TX and XDP_REDIRECT actions. If frame loss occurs in these two actions, the frames loss count should not be included in xdp_drops, because there are already xdp_tx_drops and xdp_redirect_failures to count the frame loss of these two actions, so it's better to remove xdp_drops statistic from enetc_xdp_drop() and increase xdp_drops in XDP_DROP action.

2024-10-11net: sparx5: fix source port register when mirroringDaniel Machon
When port mirroring is added to a port, the bit position of the source port, needs to be written to the register ANA_AC_PROBE_PORT_CFG. This register is replicated for n_ports > 32, and therefore we need to derive the correct register from the port number. Before this patch, we wrongly calculate the register from portno / BITS_PER_BYTE, where the divisor ought to be 32, causing any port >=8 to be written to the wrong register. We fix this, by using do_div(), where the dividend is the register, the remainder is the bit position and the divisor is now 32.

2024-10-11ipv4: give an IPv4 dev to blackhole_netdevXin Long
After commit 8d7017fd621d ("blackhole_netdev: use blackhole_netdev to invalidate dst entries"), blackhole_netdev was introduced to invalidate dst cache entries on the TX path whenever the cache times out or is flushed. When two UDP sockets (sk1 and sk2) send messages to the same destination simultaneously, they are using the same dst cache. If the dst cache is invalidated on one path (sk2) while the other (sk1) is still transmitting, sk1 may try to use the invalid dst entry. CPU1 CPU2 udp_sendmsg(sk1) udp_sendmsg(sk2) udp_send_skb() ip_output() <--- dst timeout or flushed dst_dev_put() ip_finish_output2() ip_neigh_for_gw() This results in a scenario where ip_neigh_for_gw() returns -EINVAL because blackhole_dev lacks an in_dev, which is needed to initialize the neigh in arp_constructor(). This error is then propagated back to userspace, breaking the UDP application. The patch fixes this issue by assigning an in_dev to blackhole_dev for IPv4, similar to what was done for IPv6 in commit e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"). This ensures that even when the dst entry is invalidated with blackhole_dev, it will not fail to create the neigh entry. As devinet_init() is called ealier than blackhole_netdev_init() in system booting, it can not assign the in_dev to blackhole_dev in devinet_init(). As Paolo suggested, add a separate late_initcall() in devinet.c to ensure inet_blackhole_dev_init() is called after blackhole_netdev_init().

Specifics: - Fix the TPMI_RAPL_REG_DOMAIN_INFO register offset in the TPMI part of the Intel RAPL power capping driver, make it ignore minor hardware version mismatches (which only indicate exposing additional features) and update register definitions in it to enable PL4 support (Zhang Rui) - Add Arrow Lake-U to the list of processors supporting PL4 in the MSR part of the Intel RAPL power capping driver (Sumeet Pawnikar) - Remove excess pci_disable_device() calls from the processor part of the int340x thermal driver to address a warning triggered during module unload and remove unused CPU hotplug code related to RAPL support from it (Zhang Rui)" * tag 'pm-6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: thermal: intel: int340x: processor: Add MMIO RAPL PL4 support thermal: intel: int340x: processor: Remove MMIO RAPL CPU hotplug support powercap: intel_rapl_msr: Add PL4 support for Arrowlake-U powercap: intel_rapl_tpmi: Ignore minor version change thermal: intel: int340x: processor: Fix warning during module unload powercap: intel_rapl_tpmi: Fix bogus register reading
