One of the next commits will alter the DW XPCS driver to support setting a custom device ID for the particular MDIO-device detected on the platform. The generic DW XPCS ID can be used as a custom ID as well in case if the DW XPCS-device was erroneously synthesized with no or some undefined ID. In addition to that having all supported DW XPCS device IDs defined in a single place will improve the code maintainability and readability. Note while at it rename the macros to being shorter and looking alike to the already defined NXP XPCS ID macro.

Convention is DT schemas should define all properties at the top-level and not inside of if/then schemas. That minimizes the if/then schemas and is more future proof.

Commit 31e0aa99 ("ethtool: Veto some operations during firmware flashing process") added a flag module_fw_flash_in_progress to struct net_device. As this is ethtool related state, move it to the recently created struct ethtool_netdev_state, accessed via the 'ethtool' member of struct net_device.

While creating a new RSS context, bnxt_rfs_capable() currently makes a strict check to see if the required VNICs are already available. If the current VNICs are not what is required, either too many or not enough, it will call the firmware to reserve the exact number required. There is a bug in the firmware when the driver tries to relinquish some reserved VNICs and RSS contexts. It will cause the default VNIC to lose its RSS configuration and cause receive packets to be placed incorrectly. Workaround this problem by skipping the resource reduction. The driver will not reduce the VNIC and RSS context reservations when a context is deleted. The resources will be available for use when new contexts are created later. Potentially, this workaround can cause us to run out of VNIC and RSS contexts if there are a lot of VF functions creating and deleting RSS contexts. In the future, we will conditionally disable this workaround when the firmware fix is available.

In case of any error occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init() calls mlxsw_linecard_types_fini() which performs memory deallocation again. Add pointer reset to NULL.

KMSAN reported uninit-value access in raw_lookup() [1]. Diag for raw sockets uses the pad field in struct inet_diag_req_v2 for the underlying protocol. This field corresponds to the sdiag_raw_protocol field in struct inet_diag_req_raw. inet_diag_get_exact_compat() converts inet_diag_req to inet_diag_req_v2, but leaves the pad field uninitialized. So the issue occurs when raw_lookup() accesses the sdiag_raw_protocol field. Fix this by initializing the pad field in inet_diag_get_exact_compat(). Also, do the same fix in inet_diag_dump_compat() to avoid the similar issue in the future.

Zijian Zhang says: ==================== fix OOM and order check in msg_zerocopy selftest In selftests/net/msg_zerocopy.c, it has a while loop keeps calling sendmsg on a socket with MSG_ZEROCOPY flag, and it will recv the notifications until the socket is not writable. Typically, it will start the receiving process after around 30+ sendmsgs. However, as the introduction of commit dfa2f048 ("tcp: get rid of sysctl_tcp_adv_win_scale"), the sender is always writable and does not get any chance to run recv notifications. The selftest always exits with OUT_OF_MEMORY because the memory used by opt_skb exceeds the net.core.optmem_max. Meanwhile, it could be set to a different value to trigger OOM on older kernels too. Thus, we introduce "cfg_notification_limit" to force sender to receive notifications after some number of sendmsgs. And, we find that when lock debugging is on, notifications may not come in order. Thus, we have order checking outputs managed by cfg_verbose, to avoid too many outputs in this case. ==================== Link: https://patch.msgid.link/20240701225349.3395580-1-zijianzhang@bytedance.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Do not use _test_bit() macro for testing bit. The proper macro for this is one without underline. _test_bit() is what test_bit() was prior to const-optimization. It directly calls arch_test_bit(), i.e. the arch-specific implementation (or the generic one). It's strictly _internal_ and shouldn't be used anywhere outside the actual test_bit() macro. test_bit() is a wrapper which checks whether the bitmap and the bit number are compile-time constants and if so, it calls the optimized function which evaluates this call to a compile-time constant as well. If either of them is not a compile-time constant, it just calls _test_bit(). test_bit() is the actual function to use anywhere in the kernel. IOW, calling _test_bit() avoids potential compile-time optimizations. The sensors is not a compile-time constant, thus most probably there are no object code changes before and after the patch. But anyway, we shouldn't call internal wrappers instead of the actual API.

The driver receives requests for configuring pins via the .enable callback of the PTP clock object. These requests come into the driver with flags which modify the requested behavior from userspace. Current implementation in ice does not reject flags that it doesn't support. This causes the driver to incorrectly apply requests with such flags as PTP_PEROUT_DUTY_CYCLE, or any future flags added by the kernel which it is not yet aware of. Fix this by properly validating flags in both ice_ptp_cfg_perout and ice_ptp_cfg_extts. Ensure that we check by bit-wise negating supported flags rather than just checking and rejecting known un-supported flags. This is preferable, as it ensures better compatibility with future kernels.

The ice_ptp_extts_event() function can race with ice_ptp_release() and result in a NULL pointer dereference which leads to a kernel panic. Panic occurs because the ice_ptp_extts_event() function calls ptp_clock_event() with a NULL pointer. The ice driver has already released the PTP clock by the time the interrupt for the next external timestamp event occurs. To fix this, modify the ice_ptp_extts_event() function to check the PTP state and bail early if PTP is not ready.

Extts events are disabled and enabled by the application ts2phc. However, in case where the driver is removed when the application is running, a specific extts event remains enabled and can cause a kernel crash. As a side effect, when the driver is reloaded and application is started again, remaining extts event for the channel from a previous run will keep firing and the message "extts on unexpected channel" might be printed to the user. To avoid that, extts events shall be disabled when PTP is released.

KMSAN reported uninit-value access in __unix_walk_scc() [1]. In the list_for_each_entry_reverse() loop, when the vertex's index equals it's scc_index, the loop uses the variable vertex as a temporary variable that points to a vertex in scc. And when the loop is finished, the variable vertex points to the list head, in this case scc, which is a local variable on the stack (more precisely, it's not even scc and might underflow the call stack of __unix_walk_scc(): container_of(&scc, struct unix_vertex, scc_entry)). However, the variable vertex is used under the label prev_vertex. So if the edge_stack is not empty and the function jumps to the prev_vertex label, the function will access invalid data on the stack. This causes the uninit-value access issue. Fix this by introducing a new temporary variable for the loop.

The openvswitch selftest is difficult to debug for anyone that isn't directly familiar with the openvswitch module and the specifics of the test cases. Many times when something fails, the debug log will be sparsely populated and it takes some time to understand where a failure occured. Increase the amount of details logged to the debug log by trapping all 'info' logs, and all 'ovs_sbx' commands.

Previously, the openvswitch.sh test suites would not attempt to autoload the openvswitch module. The idea was that a user who is manually running tests might not even have the OVS module loaded or configured for their own development. However, if the kernel module is configured, and the module can be autoloaded then we should just attempt to load it and run the tests. This is especially true in the CI environments, where the CI tests should be able to rely on auto loading to get the test suite running.

Device driver gets access to rxfh_dev, while rxfh is just a local copy of user space params. We need to check what RSS context ID driver assigned in rxfh_dev, not rxfh. Using rxfh leads to trying to store all contexts at index 0xffffffff. From the user perspective it leads to "driver chose duplicate ID" warnings when second context is added and inability to access any contexts even tho they were successfully created - xa_load() for the actual context ID will return NULL, and syscall will return -ENOENT. Looks like a rebasing mistake, since rxfh_dev was added relatively recently by commit fb6e30a7 ("net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool ops").

The use-after-free is actually in rswitch_tx_free(), which is inlined in rswitch_poll(). Since `skb` and `gq->skbs[gq->dirty]` are in fact the same pointer, the skb is first freed using dev_kfree_skb_any(), then the value in skb->len is used to update the interface statistics. Let's move around the instructions to use skb->len before the skb is freed. This bug is trivial to reproduce using KFENCE. It will trigger a splat every few packets.

As predicted by David running the test on a machine with a single interface is a bit unreliable. We try to send 20k packets with iperf and expect fewer than 10k packets on the default context. The test isn't very quick, iperf will usually send 100k packets by the time we stop it. So we're off by 5x on the number of iperf packets but still expect default context to only get the hardcoded 10k. The intent is to make sure we get noticeably less traffic on the default context. Use half of the resulting iperf traffic instead of the hard coded 10k. Link: https://patch.msgid.link/20240702233728.4183387-1-kuba@kernel.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>
