As mentioned in a previous commit of this series, using the 'net' structure via 'current' is not recommended for different reasons: - Inconsistency: getting info from the reader's/writer's netns vs only from the opener's netns. - current->nsproxy can be NULL in some cases, resulting in an 'Oops' (null-ptr-deref), e.g. when the current task is exiting, as spotted by syzbot [1] using acct(2). The per-netns structure can be obtained from the table->data using container_of(), then the 'net' one can be retrieved from the listen socket (if available).

Using the 'net' structure via 'current' is not recommended for different reasons. First, if the goal is to use it to read or write per-netns data, this is inconsistent with how the "generic" sysctl entries are doing: directly by only using pointers set to the table entry, e.g. table->data. Linked to that, the per-netns data should always be obtained from the table linked to the netns it had been created for, which may not coincide with the reader's or writer's netns. Another reason is that access to current->nsproxy->netns can oops if attempted when current->nsproxy had been dropped when the current task is exiting. This is what syzbot found, when using acct(2): Oops: general protection fault, probably for non-canonical address 0xdffffc0000000005: 0000 [#1] PREEMPT SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f] CPU: 1 UID: 0 PID: 5924 Comm: syz-executor Not tainted 6.13.0-rc5-syzkaller-00004-gccb98ccef0e5 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024 RIP: 0010:proc_scheduler+0xc6/0x3c0 net/mptcp/ctrl.c:125 Code: 03 42 80 3c 38 00 0f 85 fe 02 00 00 4d 8b a4 24 08 09 00 00 48 b8 00 00 00 00 00 fc ff df 49 8d 7c 24 28 48 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 cc 02 00 00 4d 8b 7c 24 28 48 8d 84 24 c8 00 00 RSP: 0018:ffffc900034774e8 EFLAGS: 00010206 RAX: dffffc0000000000 RBX: 1ffff9200068ee9e RCX: ffffc90003477620 RDX: 0000000000000005 RSI: ffffffff8b08f91e RDI: 0000000000000028 RBP: 0000000000000001 R08: ffffc90003477710 R09: 0000000000000040 R10: 0000000000000040 R11: 00000000726f7475 R12: 0000000000000000 R13: ffffc90003477620 R14: ffffc90003477710 R15: dffffc0000000000 FS: 0000000000000000(0000) GS:ffff8880b8700000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fee3cd452d8 CR3: 000000007d116000 CR4: 00000000003526f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> proc_sys_call_handler+0x403/0x5d0 fs/proc/proc_sysctl.c:601 __kernel_write_iter+0x318/0xa80 fs/read_write.c:612 __kernel_write+0xf6/0x140 fs/read_write.c:632 do_acct_process+0xcb0/0x14a0 kernel/acct.c:539 acct_pin_kill+0x2d/0x100 kernel/acct.c:192 pin_kill+0x194/0x7c0 fs/fs_pin.c:44 mnt_pin_kill+0x61/0x1e0 fs/fs_pin.c:81 cleanup_mnt+0x3ac/0x450 fs/namespace.c:1366 task_work_run+0x14e/0x250 kernel/task_work.c:239 exit_task_work include/linux/task_work.h:43 [inline] do_exit+0xad8/0x2d70 kernel/exit.c:938 do_group_exit+0xd3/0x2a0 kernel/exit.c:1087 get_signal+0x2576/0x2610 kernel/signal.c:3017 arch_do_signal_or_restart+0x90/0x7e0 arch/x86/kernel/signal.c:337 exit_to_user_mode_loop kernel/entry/common.c:111 [inline] exit_to_user_mode_prepare include/linux/entry-common.h:329 [inline] __syscall_exit_to_user_mode_work kernel/entry/common.c:207 [inline] syscall_exit_to_user_mode+0x150/0x2a0 kernel/entry/common.c:218 do_syscall_64+0xda/0x250 arch/x86/entry/common.c:89 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7fee3cb87a6a Code: Unable to access opcode bytes at 0x7fee3cb87a40.

Nvidia's Tegra MGBE controllers require the IOMMU "Stream ID" (SID) to be written to the MGBE_WRAP_AXI_ASID0_CTRL register. The current driver is hard coded to use MGBE0's SID for all controllers. This causes softirq time outs and kernel panics when using controllers other than MGBE0.

The Tegra234 SOC has 4 MGBE controllers, however Nvidia's Developer Kit only uses MGBE0 which is why the bug was not found previously. Connect Tech has many products that use 2 (or more) MGBE controllers. The solution is to read the controller's SID from the existing "iommus" device tree property. The 2nd field of the "iommus" device tree property is the controller's SID. Device tree snippet from tegra234.dtsi showing MGBE1's "iommus" property: smmu_niso0: iommu@12000000 { compatible = "nvidia,tegra234-smmu", "nvidia,smmu-500"; ... } /* MGBE1 */ ethernet@6900000 { compatible = "nvidia,tegra234-mgbe"; ... iommus = <&smmu_niso0 TEGRA234_SID_MGBE_VF1>; ... } Nvidia's arm-smmu driver reads the "iommus" property and stores the SID in the MGBE device's "fwspec" struct. The dwmac-tegra driver can access the SID using the tegra_dev_iommu_get_stream_id() helper function found in linux/iommu.h. Calling tegra_dev_iommu_get_stream_id() should not fail unless the "iommus" property is removed from the device tree or the IOMMU is disabled. While the Tegra234 SOC technically supports bypassing the IOMMU, it is not supported by the current firmware, has not been tested and not recommended.

Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error). As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases. This should not make a noticeable difference in practice, and thus it's not worth complicating the code to preserve the old behaviour. Fixes: 546ea84d ("sched: sch_cake: fix bulk flow accounting logic for host fairness") Reported-by:

We found a timeout problem with the pldm command on our system. The reason is that the MCTP-I3C driver has a race condition when receiving multiple-packet messages in multi-thread, resulting in a wrong packet order problem. We identified this problem by adding a debug message to the mctp_i3c_read function. According to the MCTP spec, a multiple-packet message must be composed in sequence, and if there is a wrong sequence, the whole message will be discarded and wait for the next SOM. For example, SOM → Pkt Seq #2 → Pkt Seq #1 → Pkt Seq #3 → EOM. Therefore, we try to solve this problem by adding a mutex to the mctp_i3c_read function. Before the modification, when a command requesting a multiple-packet message response is sent consecutively, an error usually occurs within 100 loops. After the mutex, it can go through 40000 loops without any error, and it seems to run well. Fixes: c8755b29 ("mctp i3c: MCTP I3C driver") Signed-off-by:

The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs 1024-1279 are in different BAR space addresses. However, hclge_fetch_pf_reg does not distinguish the tqp space information when reading the tqp space information. When the number of TQPs is greater than 1024, access bar space overwriting occurs. The problem of different segments has been considered during the initialization of tqp.io_base. Therefore, tqp.io_base is directly used when the queue is read in hclge_fetch_pf_reg.

This patch modifies the implementation of debugfs: When the user process stops unexpectedly, not all data of the file system is read. In this case, the save_buf pointer is not released. When the user process is called next time, save_buf is used to copy the cached data to the user space. As a result, the queried data is stale. To solve this problem, this patch implements .open() and .release() handler for debugfs file_operations. moving allocation buffer and execution of the cmd to the .open() handler and freeing in to the .release() handler. Allocate separate buffer for each reader and associate the buffer with the file pointer. When different user read processes no longer share the buffer, the stale data problem is fixed.

When a reset type that is not supported by the driver is input, a reset pending flag bit of the HNAE3_NONE_RESET type is generated in reset_pending. The driver does not have a mechanism to clear this type of error. As a result, the driver considers that the reset is not complete. This patch provides a mechanism to clear the HNAE3_NONE_RESET flag and the parameter of hnae3_ae_ops.set_default_reset_request is verified.

The NAPI IDs were not fully exposed to user space prior to the netlink API, so they were never namespaced. The netlink API must ensure that at the very least NAPI instance belongs to the same netns as the owner of the genl sock. napi_by_id() can become static now, but it needs to move because of dev_get_by_napi_id().
