2023-12-04net/mlx5e: TC, Don't offload post action rule if not supportedChris Mi
If post action is not supported, eg. ignore_flow_level is not supported, don't offload post action rule. Otherwise, will hit panic [1]. Fix it by checking if post action table is valid or not.

2023-12-04net/mlx5e: Fix possible deadlock on mlx5e_tx_timeout_workMoshe Shemesh
Due to the cited patch, devlink health commands take devlink lock and this may result in deadlock for mlx5e_tx_reporter as it takes local state_lock before calling devlink health report and on the other hand devlink health commands such as diagnose for same reporter take local state_lock after taking devlink lock (see kernel log below). To fix it, remove local state_lock from mlx5e_tx_timeout_work() before calling devlink_health_report() and take care to cancel the work before any call to close channels, which may free the SQs that should be handled by the work. Before cancel_work_sync(), use current_work() to check we are not calling it from within the work, as mlx5e_tx_timeout_work() itself may close the channels and reopen as part of recovery flow. While removing state_lock from mlx5e_tx_timeout_work() keep rtnl_lock to ensure no change in netdev->real_num_tx_queues, but use rtnl_trylock() and a flag to avoid deadlock by calling cancel_work_sync() before closing the channels while holding rtnl_lock too.

2023-12-04net/mlx5e: Check the number of elements before walk TC rhashtableJianbo Liu
After IPSec TX tables are destroyed, the flow rules in TC rhashtable, which have the destination to IPSec, are restored to the original one, the uplink. However, when the device is in switchdev mode and unload driver with IPSec rules configured, TC rhashtable cleanup is done before IPSec cleanup, which means tc_ht->tbl is already freed when walking TC rhashtable, in order to restore the destination. So add the checking before walking to avoid unexpected behavior.

2023-12-04net/mlx5e: Reduce eswitch mode_lock protection contextJianbo Liu
Currently eswitch mode_lock is so heavy, for example, it's locked during the whole process of the mode change, which may need to hold other locks. As the mode_lock is also used by IPSec to block mode and encap change now, it is easy to cause lock dependency. Since some of protections are also done by devlink lock, the eswitch mode_lock is not needed at those places, and thus the possibility of lockdep issue is reduced.

2023-12-04packet: Move reference count in packet_sock to atomic_long_tDaniel Borkmann
In some potential instances the reference count on struct packet_sock could be saturated and cause overflows which gets the kernel a bit confused. To prevent this, move to a 64-bit atomic reference count on 64-bit architectures to prevent the possibility of this type to overflow. Because we can not handle saturation, using refcount_t is not possible in this place. Maybe someday in the future if it changes it could be used. Also, instead of using plain atomic64_t, use atomic_long_t instead. 32-bit machines tend to be memory-limited (i.e. anything that increases a reference uses so much memory that you can't actually get to 2**32 references). 32-bit architectures also tend to have serious problems with 64-bit atomics. Hence, atomic_long_t is the more natural solution.

2023-12-04mlxbf-bootctl: correctly identify secure boot with development keysDavid Thompson
The secure boot state of the BlueField SoC is represented by two bits: 0 = production state 1 = secure boot enabled 2 = non-secure (secure boot disabled) 3 = RMA state There is also a single bit to indicate whether production keys or development keys are being used when secure boot is enabled. This single bit (specified by MLXBF_BOOTCTL_SB_DEV_MASK) only has meaning if secure boot state equals 1 (secure boot enabled). The secure boot states are as follows: - “GA secured” is when secure boot is enabled with official production keys. - “Secured (development)” is when secure boot is enabled with development keys. Without this fix “GA Secured” is displayed on development cards which is misleading. This patch updates the logic in "lifecycle_state_show()" to handle the case where the SoC is configured for secure boot and is using development keys.

2023-12-04r8152: Hold the rtnl_lock for all of resetDouglas Anderson
As of commit d9962b0d4202 ("r8152: Block future register access if register access fails") there is a race condition that can happen between the USB device reset thread and napi_enable() (not) getting called during rtl8152_open(). Specifically: * While rtl8152_open() is running we get a register access error that's _not_ -ENODEV and queue up a USB reset. * rtl8152_open() exits before calling napi_enable() due to any reason (including usb_submit_urb() returning an error). In that case: * Since the USB reset is perform in a separate thread asynchronously, it can run at anytime USB device lock is not held - even before rtl8152_open() has exited with an error and caused __dev_open() to clear the __LINK_STATE_START bit. * The rtl8152_pre_reset() will notice that the netif_running() returns true (since __LINK_STATE_START wasn't cleared) so it won't exit early. * rtl8152_pre_reset() will then hang in napi_disable() because napi_enable() was never called. We can fix the race by making sure that the r8152 reset routines don't run at the same time as we're opening the device. Specifically we need the reset routines in their entirety rely on the return value of netif_running(). The only way to reliably depend on that is for them to hold the rntl_lock() mutex for the duration of reset. Grabbing the rntl_lock() mutex for the duration of reset seems like a long time, but reset is not expected to be common and the rtnl_lock() mutex is already held for long durations since the core grabs it around the open/close calls.

2023-12-02r8169: fix rtl8125b PAUSE frames blasting when suspendedChunHao Lin
When FIFO reaches near full state, device will issue pause frame. If pause slot is enabled(set to 1), in this time, device will issue pause frame only once. But if pause slot is disabled(set to 0), device will keep sending pause frames until FIFO reaches near empty state. When pause slot is disabled, if there is no one to handle receive packets, device FIFO will reach near full state and keep sending pause frames. That will impact entire local area network. This issue can be reproduced in Chromebox (not Chromebook) in developer mode running a test image (and v5.10 kernel): 1) ping -f $CHROMEBOX (from workstation on same local network) 2) run "powerd_dbus_suspend" from command line on the $CHROMEBOX 3) ping $ROUTER (wait until ping fails from workstation) Takes about ~20-30 seconds after step 2 for the local network to stop working. Fix this issue by enabling pause slot to only send pause frame once when FIFO reaches near full state.

2023-12-01net/tg3: fix race condition in tg3_reset_task()Thinh Tran
When an EEH error is encountered by a PCI adapter, the EEH driver modifies the PCI channel's state as shown below: enum { /* I/O channel is in normal state */ pci_channel_io_normal = (__force pci_channel_state_t) 1, /* I/O to channel is blocked */ pci_channel_io_frozen = (__force pci_channel_state_t) 2, /* PCI card is dead */ pci_channel_io_perm_failure = (__force pci_channel_state_t) 3, }; If the same EEH error then causes the tg3 driver's transmit timeout logic to execute, the tg3_tx_timeout() function schedules a reset task via tg3_reset_task_schedule(), which may cause a race condition between the tg3 and EEH driver as both attempt to recover the HW via a reset action. EEH driver gets error event --> eeh_set_channel_state() and set device to one of error state above scheduler: tg3_reset_task() get returned error from tg3_init_hw() --> dev_close() shuts down the interface tg3_io_slot_reset() and tg3_io_resume() fail to reset/resume the device To resolve this issue, we avoid the race condition by checking the PCI channel state in the tg3_reset_task() function and skip the tg3 driver initiated reset when the PCI channel is not in the normal state. (The driver has no access to tg3 device registers at this point and cannot even complete the reset task successfully without external assistance.) We'll leave the reset procedure to be managed by the EEH driver which calls the tg3_io_error_detected(), tg3_io_slot_reset() and tg3_io_resume() functions as appropriate. Adding the same checking in tg3_dump_state() to avoid dumping all device registers when the PCI channel is not in the normal state.

The fix is rather simple. For 32bit offset branch insn, the adjusted offset compares to [S32_MIN, S32_MAX] and then verification succeeded.

Pull io_uring fixes from Jens Axboe: - Fix an issue with discontig page checking for IORING_SETUP_NO_MMAP - Fix an issue with not allowing IORING_SETUP_NO_MMAP also disallowing mmap'ed buffer rings - Fix an issue with deferred release of memory mapped pages - Fix a lockdep issue with IORING_SETUP_NO_MMAP - Use fget/fput consistently, even from our sync system calls. No real issue here, but if we were ever to allow closing io_uring descriptors it would be required. Let's play it safe and just use the full ref counted versions upfront.
