When the name_assign_type attribute was introduced (commit 685343fc, "net: add name_assign_type netdev attribute"), the loopback device was explicitly mentioned as one which would make use of NET_NAME_PREDICTABLE: The name_assign_type attribute gives hints where the interface name of a given net-device comes from. These values are currently defined: ... NET_NAME_PREDICTABLE: The ifname has been assigned by the kernel in a predictable way that is guaranteed to avoid reuse and always be the same for a given device. Examples include statically created devices like the loopback device [...] Switch to that so that reading /sys/class/net/lo/name_assign_type produces something sensible instead of returning -EINVAL.

Currently, when a FEC device is brought up, the irq coalesce settings are reset to their default values (1000us, 200 frames). That's unexpected, and breaks for example use of an appropriate .link file to make systemd-udev apply the desired settings (https://www.freedesktop.org/software/systemd/man/systemd.link.html), or any other method that would do a one-time setup during early boot. Refactor the code so that fec_restart() instead uses fec_enet_itr_coal_set(), which simply applies the settings that are stored in the private data, and initialize that private data with the default values.

This patch addresses pfc_alloc_status array overflow occurring for send queue index value greater than PFC priority. Queue index can be greater than supported PFC priority for multiple scenarios (e.g. QoS, during non zero SMQ allocation for a PF/VF). In those scenarios the API should return default tx scheduler '0'. This is causing mbox errors as otx2_get_smq_idx returing invalid smq value.

Defines prefixed with "CONFIG" should be limited to proper Kconfig options, that are introduced in a Kconfig file. Here, constants for bitmap indices of some configs are defined and these defines begin with the config's name, and are suffixed with BITMAP_IDX. To avoid defines prefixed with "CONFIG", name these constants BITMAP_IDX_FOR_CONFIG_XYZ instead of CONFIG_XYZ_BITMAP_IDX. No functional change. Signed-off-by:

The watchdog timer is used to monitor whether the process of transmitting data is timeout. If we use qlcnic driver, the dev_watchdog() that is the timer handler of watchdog timer will call qlcnic_tx_timeout() to process the timeout. But the qlcnic_tx_timeout() calls msleep(), as a result, the sleep-in-atomic-context bugs will happen. The processes are shown below: (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver msleep --------------------------- (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver qlcnic_83xx_recover_driver_lock msleep Fix by changing msleep() to mdelay(), the mdelay() is busy-waiting and the bugs could be mitigated.

Microchip USB Analyzer can activate the internal termination resistors by setting the "termination" option ON, or OFF to to deactivate them. As I've observed, both with my oscilloscope and captured USB packets below, you must send "0" to turn it ON, and "1" to turn it OFF. From the schematics in the user's guide, I can confirm that you must drive the CAN_RES signal LOW "0" to activate the resistors. Reverse the argument value of usb_msg.termination to fix this. These are the two commands sequence, ON then OFF. > No. Time Source Destination Protocol Length Info > 1 0.000000 host 1.3.1 USB 46 URB_BULK out > > Frame 1: 46 bytes on wire (368 bits), 46 bytes captured (368 bits) > USB URB > Leftover Capture Data: a80000000000000000000000000000000000a8 > > No. Time Source Destination Protocol Length Info > 2 4.372547 host 1.3.1 USB 46 URB_BULK out > > Frame 2: 46 bytes on wire (368 bits), 46 bytes captured (368 bits) > USB URB > Leftover Capture Data: a80100000000000000000000000000000000a9 Signed-off-by:

pci_get_device() will decrease the reference count for the *from* parameter. So we don't need to call put_device() to decrease the reference. Let's remove the put_device() in the loop and only decrease the reference count of the returned 'pdev' for the last loop because it will not be passed to pci_get_device() as input parameter. We don't need to check if 'pdev' is NULL because it is already checked inside pci_dev_put(). Also add pci_dev_put() for the error path.

In vp_modern_find_vqs(), all queues will be selected and activated, but once queues are enabled there is no way to go back except reset. Fix it by reset virtio device on error handling path. This makes error handling follow the same order as normal device cleanup in virtnet_remove() which does: unregister, destroy failover, then reset. And that flow is better tested than error handling so we can be reasonably sure it works well.

Vladimir Oltean authored
In the blamed commit, a rudimentary reallocation procedure for RX buffer descriptors was implemented, for the situation when their format changes between normal (no PTP) and extended (PTP). enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence, and this sequence loses information which was previously configured in the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call. The TX ring priority is configured by tc-mqprio and tc-taprio, and affects important things for TSN such as the TX time of packets. The issue manifests itself most visibly by the fact that isochron --txtime reports premature packet transmissions when PTP is first enabled on an enetc interface. Save the TX ring priority in a new field in struct enetc_bdr (occupies a 2 byte hole on arm64) in order to make this survive a ring reconfiguration.

Martin Faltesek authored
The transaction buffer is allocated by using the size of the packet buf, and subtracting two which seems intended to remove the two tags which are not present in the target structure. This calculation leads to under counting memory because of differences between the packet contents and the target structure. The aid_len field is a u8 in the packet, but a u32 in the structure, resulting in at least 3 bytes always being under counted. Further, the aid data is a variable length field in the packet, but fixed in the structure, so if this field is less than the max, the difference is added to the under counting. To fix, perform validation checks progressively to safely reach the next field, to determine the size of both buffers and verify both tags. Once all validation checks pass, allocate the buffer and copy the data. This eliminates freeing memory on the error path, as validation checks are moved ahead of memory allocation. Reported-by:

Martin Faltesek authored
The first validation check for EVT_TRANSACTION has two different checks tied together with logical AND. One is a check for minimum packet length, and the other is for a valid aid_tag. If either condition is true (fails), then an error should be triggered. The fix is to change && to ||. Reported-by:

In com20020_probe(), if com20020_config() fails, dev and info will not be freed, which will lead to a memory leak. This patch adds freeing dev and info after com20020_config() fails to fix this bug. Compile tested only. Fixes: 15b99ac1 ("[PATCH] pcmcia: add return value to _config() functions") Signed-off-by:

In mtk_ppe_init(), when dmam_alloc_coherent() or devm_kzalloc() failed, the rhashtable ppe->l2_flows isn't destroyed. Fix it. In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() or register_netdev() failed, have the same problem. Fix it.
