2022-11-12mISDN: fix possible memory leak in mISDN_dsp_element_register()Yang Yingliang1-1/+2
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, use put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0. The 'entry' is going to be freed in mISDN_dsp_dev_release(), so the kfree() is removed. list_del() is called in mISDN_dsp_dev_release(), so it need be initialized.

2022-11-11bpf: Initialize same number of free nodes for each pcpu_freelistXu Kuohai1-12/+11
pcpu_freelist_populate() initializes nr_elems / num_possible_cpus() + 1 free nodes for some CPUs, and then possibly one CPU with fewer nodes, followed by remaining cpus with 0 nodes. For example, when nr_elems == 256 and num_possible_cpus() == 32, CPU 0~27 each gets 9 free nodes, CPU 28 gets 4 free nodes, CPU 29~31 get 0 free nodes, while in fact each CPU should get 8 nodes equally. This patch initializes nr_elems / num_possible_cpus() free nodes for each CPU firstly, then allocates the remaining free nodes by one for each CPU until no free nodes left.

2022-11-11selftests: bpf: Add a test when bpf_probe_read_kernel_str() returns EFAULTAlban Crequy2-0/+12
This commit tests previous fix of bpf_probe_read_kernel_str(). The BPF helper bpf_probe_read_kernel_str should return -EFAULT when given a bad source pointer and the target buffer should only be modified to make the string NULL terminated. bpf_probe_read_kernel_str() was previously inserting a NULL before the beginning of the dst buffer. This test should ensure that the implementation stays correct for now on.

2022-11-11nfp: change eeprom length to max length enumeratorsJaco Coetzee1-3/+3
Extend the size of QSFP EEPROM for types SSF8436 and SFF8636 from 256 to 640 bytes in order to expose all the EEPROM pages by ethtool. For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of EEPROM data for ethtool's get_module_eeprom() callback, resulting in "netlink error: Invalid argument" when an EEPROM read with an offset larger than 256 bytes is attempted. Changing the length enumerators to the _MAX_LEN variants exposes all 640 bytes of the EEPROM allowing upper pages 1, 2 and 3 to be read.

2022-11-09net/mlx5e: Fix usage of DMA sync APIMaxim Mikityanskiy2-15/+16
DMA sync functions should use the same direction that was used by DMA mapping. Use DMA_BIDIRECTIONAL for XDP_TX from regular RQ, which reuses the same mapping that was used for RX, and DMA_TO_DEVICE for XDP_TX from XSK RQ and XDP_REDIRECT, which establish a new mapping in this direction. On the RX side, use the same direction that was used when setting up the mapping (DMA_BIDIRECTIONAL for XDP, DMA_FROM_DEVICE otherwise). Also don't skip sync for device when establishing a DMA_FROM_DEVICE mapping for RX, as some architectures (ARM) may require invalidating caches before the device can use the mapping. It doesn't break the bugfix made in commit 0b7cfa4082fb ("net/mlx5e: Fix page DMA map/unmap attributes"), since the bug happened on unmap.

When adding such bond device to a bridge mlx5 bridge code will not consider it as offload-capable, skip creating necessary bookkeeping and fail any further bridge offload-related commands with it (setting VLANs, offloading FDBs, etc.).
