2022-10-29platform/loongarch: laptop: Fix possible UAF and simplify ↵Yang Yingliang
generic_acpi_laptop_init() Currently the return value of 'sub_driver->init' is not checked. If sparse_keymap_setup() called in the init function fails, 'generic_ inputdev' is freed, then it will lead a UAF when using it in generic_ acpi_laptop_init(). Fix it by checking the return value and setting generic_inputdev to NULL after free, so as to avoid double free it. The error code in generic_subdriver_init() is always negative, so the return of generic_subdriver_init() can be simplified.

2022-10-29random: use arch_get_random*_early() in random_init()Jean-Philippe Brucker
While reworking the archrandom handling, commit d349ab99eec7 ("random: handle archrandom with multiple longs") switched to the non-early archrandom helpers in random_init(), which broke initialization of the entropy pool from the arm64 random generator. Indeed at that point the arm64 CPU features, which verify that all CPUs have compatible capabilities, are not finalized so arch_get_random_seed_longs() is unsuccessful. Instead random_init() should use the _early functions, which check only the boot CPU on arm64. On other architectures the _early functions directly call the normal ones.

2022-10-27net: enetc: survive memory pressure without crashingVladimir Oltean
Under memory pressure, enetc_refill_rx_ring() may fail, and when called during the enetc_open() -> enetc_setup_rxbdr() procedure, this is not checked for. An extreme case of memory pressure will result in exactly zero buffers being allocated for the RX ring, and in such a case it is expected that hardware drops all RX packets due to lack of buffers. This does not happen, because the reset-default value of the consumer and produces index is 0, and this makes the ENETC think that all buffers have been initialized and that it owns them (when in reality none were). The hardware guide explains this best: | Configure the receive ring producer index register RBaPIR with a value | of 0. The producer index is initially configured by software but owned | by hardware after the ring has been enabled. Hardware increments the | index when a frame is received which may consume one or more BDs. | Hardware is not allowed to increment the producer index to match the | consumer index since it is used to indicate an empty condition. The ring | can hold at most RBLENR[LENGTH]-1 received BDs. | | Configure the receive ring consumer index register RBaCIR. The | consumer index is owned by software and updated during operation of the | of the BD ring by software, to indicate that any receive data occupied | in the BD has been processed and it has been prepared for new data. | - If consumer index and producer index are initialized to the same | value, it indicates that all BDs in the ring have been prepared and | hardware owns all of the entries. | - If consumer index is initialized to producer index plus N, it would | indicate N BDs have been prepared. Note that hardware cannot start if | only a single buffer is prepared due to the restrictions described in | (2). | - Software may write consumer index to match producer index anytime | while the ring is operational to indicate all received BDs prior have | been processed and new BDs prepared for hardware. Normally, the value of rx_ring->rcir (consumer index) is brought in sync with the rx_ring->next_to_use software index, but this only happens if page allocation ever succeeded. When PI==CI==0, the hardware appears to receive frames and write them to DMA address 0x0 (?!), then set the READY bit in the BD. The enetc_clean_rx_ring() function (and its XDP derivative) is naturally not prepared to handle such a condition. It will attempt to process those frames using the rx_swbd structure associated with index i of the RX ring, but that structure is not fully initialized (enetc_new_page() does all of that). So what happens next is undefined behavior. To operate using no buffer, we must initialize the CI to PI + 1, which will block the hardware from advancing the CI any further, and drop everything. The issue was seen while adding support for zero-copy AF_XDP sockets, where buffer memory comes from user space, which can even decide to supply no buffers at all (example: "xdpsock --txonly"). However, the bug is present also with the network stack code, even though it would take a very determined person to trigger a page allocation failure at the perfect time (a series of ifup/ifdown under memory pressure should eventually reproduce it given enough retries).

2022-10-27net/mlx5: Fix possible use-after-free in async command interfaceTariq Toukan
mlx5_cmd_cleanup_async_ctx should return only after all its callback handlers were completed. Before this patch, the below race between mlx5_cmd_cleanup_async_ctx and mlx5_cmd_exec_cb_handler was possible and lead to a use-after-free: 1. mlx5_cmd_cleanup_async_ctx is called while num_inflight is 2 (i.e. elevated by 1, a single inflight callback). 2. mlx5_cmd_cleanup_async_ctx decreases num_inflight to 1. 3. mlx5_cmd_exec_cb_handler is called, decreases num_inflight to 0 and is about to call wake_up(). 4. mlx5_cmd_cleanup_async_ctx calls wait_event, which returns immediately as the condition (num_inflight == 0) holds. 5. mlx5_cmd_cleanup_async_ctx returns. 6. The caller of mlx5_cmd_cleanup_async_ctx frees the mlx5_async_ctx object. 7. mlx5_cmd_exec_cb_handler goes on and calls wake_up() on the freed object. Fix it by syncing using a completion object. Mark it completed when num_inflight reaches 0.

2022-10-27net/mlx5e: Do not increment ESN when updating IPsec ESN stateHyong Youb Kim
An offloaded SA stops receiving after about 2^32 + replay_window packets. For example, when SA reaches <seq-hi 0x1, seq 0x2c>, all subsequent packets get dropped with SA-icv-failure (integrity_failed). To reproduce the bug: - ConnectX-6 Dx with crypto enabled (FW 22.30.1004) - ipsec.conf: nic-offload = yes replay-window = 32 esn = yes salifetime=24h - Run netperf for a long time to send more than 2^32 packets netperf -H <device-under-test> -t TCP_STREAM -l 20000 When 2^32 + replay_window packets are received, the replay window moves from the 2nd half of subspace (overlap=1) to the 1st half (overlap=0). The driver then updates the 'esn' value in NIC (i.e. seq_hi) as follows. seq_hi = xfrm_replay_seqhi(seq_bottom) new esn in NIC = seq_hi + 1 The +1 increment is wrong, as seq_hi already contains the correct seq_hi. For example, when seq_hi=1, the driver actually tells NIC to use seq_hi=2 (esn). This incorrect esn value causes all subsequent packets to fail integrity checks (SA-icv-failure). So, do not increment.

Queueing packets doesn't guarantee their transmission. Update TX stats after hardware confirms consuming submitted data. This also fixes a possible race and NULL dereference. bcm4908_enet_start_xmit() could try to access skb after freeing it in the bcm4908_enet_poll_tx().

2022-10-27rbd: fix possible memory leak in rbd_sysfs_init()Yang Yingliang
If device_register() returns error in rbd_sysfs_init(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked. As comment of device_add() says, it should call put_device() to drop the reference count that was set in device_initialize() when it fails, so the name can be freed in kobject_cleanup(). Fault injection test can trigger this problem: unreferenced object 0xffff88810173aa78 (size 8): comm "modprobe", pid 247, jiffies 4294714278 (age 31.789s) hex dump (first 8 bytes): 72 62 64 00 81 88 ff ff rbd..... backtrace: [<00000000f58fae56>] __kmalloc_node_track_caller+0x44/0x1b0 [<00000000bdd44fe7>] kstrdup+0x3a/0x70 [<00000000f7844d0b>] kstrdup_const+0x63/0x80 [<000000001b0a0eeb>] kvasprintf_const+0x10b/0x190 [<00000000a47bd894>] kobject_set_name_vargs+0x56/0x150 [<00000000d5edbf18>] dev_set_name+0xab/0xe0 [<00000000f5153e80>] device_add+0x106/0x1f20 Fixes: dfc5606dc513 ("rbd: replace the rbd sysfs interface") Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Reviewed-by: Alex Elder <elder@linaro.org> Link: https://lore.kernel.org/r/20221027091918.2294132-1-yangyingliang@huawei.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
