2023-12-12net: dl2k: Use proper conversion of dev_addr before IO to deviceAndy Shevchenko
The driver is using iowriteXX()/ioreadXX() APIs which are LE IO accessors simplified as 1. Convert given value _from_ CPU _to_ LE 2. Write it to the device as is The dev_addr is a byte stream, but because the driver uses 16-bit IO accessors, it wants to perform double conversion on BE CPUs, but it took it wrong, as it effectivelly does two times _from_ CPU _to_ LE. What it has to do is to consider dev_addr as an array of LE16 and hence do _from_ LE _to_ CPU conversion, followed by implied _from_ CPU _to_ LE in the iowrite16(). To achieve that, use get_unaligned_le16(). This will make it correct and allows to avoid sparse warning as reported by LKP.

2023-12-10qlcnic: replace deprecated strncpy with strscpyJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect fw_info->fw_file_name to be NUL-terminated based on its use within _request_firmware_prepare() wherein `name` refers to it: | if (firmware_request_builtin_buf(firmware, name, dbuf, size)) { | dev_dbg(device, "using built-in %s\n", name); | return 0; /* assigned */ | } ... and with firmware_request_builtin() also via `name`: | if (strcmp(name, b_fw->name) == 0) { There is no evidence that NUL-padding is required. Additionally replace size macro (QLC_FW_FILE_NAME_LEN) with sizeof(fw_info->fw_file_name) to more directly tie the maximum buffer size to the destination buffer: Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

2023-12-10octeontx2-af: fix a use-after-free in rvu_nix_register_reportersZhipeng Lu
The rvu_dl will be freed in rvu_nix_health_reporters_destroy(rvu_dl) after the create_workqueue fails, and after that free, the rvu_dl will be translate back through the following call chain: rvu_nix_health_reporters_destroy |-> rvu_nix_health_reporters_create |-> rvu_health_reporters_create |-> rvu_register_dl (label err_dl_health) Finally. in the err_dl_health label, rvu_dl being freed again in rvu_health_reporters_destroy(rvu) by rvu_nix_health_reporters_destroy. In the second calls of rvu_nix_health_reporters_destroy, however, it uses rvu_dl->rvu_nix_health_reporter, which is already freed at the end of rvu_nix_health_reporters_destroy in the first call. So this patch prevents the first destroy by instantly returning -ENONMEN when create_workqueue fails. In addition, since the failure of create_workqueue is the only entrence of label err, it has been integrated into the error-handling path of create_workqueue.

The old implementation extracted VLAN TCI info from the payload before the VLAN tag has been pushed in the payload. Another problem was that the VLAN TCI was extracted even if the packet did not have VLAN protocol header. This resulted in invalid VLAN TCI and as a consequence a random queue was computed. This patch fixes the above issues and use the VLAN TCI from the skb if it is present or VLAN TCI from payload if present. If no VLAN header is present queue 0 is selected.

In addition, internal loopback packets will never have a valid timestamp and the timestamp field will always be zero.

When MCS external bypass is disabled, MCS returns additional 2 credits(32B) for every packet Tx'ed on LMAC. To account for these extra credits, NIX_AF_TX_LINKX_NORM_CREDIT.CC_MCS_CNT needs to be configured as otherwise NIX Tx credits would overflow and will never be returned to idle state credit count causing issues with credit control and MTU change.
