2023-05-26cxl: Explicitly initialize resources when media is not readyDave Jiang
When media is not ready do not assume that the capacity information from the identify command is valid, i.e. ->total_bytes ->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly zero out the capacity resources and exit early. Given zero-init of those fields this patch is functionally equivalent to the prior state, but it improves readability and robustness going forward.

2023-05-26mtd: spi-nor: Fix divide by zero for spi-nor-generic flashesTudor Ambarus
We failed to initialize n_banks for spi-nor-generic flashes, which caused a devide by zero when computing the bank_size. By default we consider that all chips have a single bank. Initialize the default number of banks for spi-nor-generic flashes. Even if the bug is fixed with this simple initialization, check the n_banks value before dividing so that we make sure this kind of bug won't occur again if some other struct instance is created uninitialized.

2023-05-26media: cec: core: don't set last_initiator if tx in progressHans Verkuil
When a message was received the last_initiator is set to 0xff. This will force the signal free time for the next transmit to that for a new initiator. However, if a new transmit is already in progress, then don't set last_initiator, since that's the initiator of the current transmit. Overwriting this would cause the signal free time of a following transmit to be that of the new initiator instead of a next transmit.

2023-05-25net: stmmac: fix call trace when stmmac_xdp_xmit() is invokedWei Fang
We encountered a kernel call trace issue which was related to ndo_xdp_xmit callback on our i.MX8MP platform. The reproduce steps show as follows. 1. The FEC port (eth0) connects to a PC port, and the PC uses pktgen_sample03_burst_single_flow.sh to generate packets and send these packets to the FEC port. Notice that the script must be executed before step 2. 2. Run the "./xdp_redirect eth0 eth1" command on i.MX8MP, the eth1 interface is the dwmac. Then there will be a call trace issue soon. Please see the log for more details. The root cause is that the NETDEV_XDP_ACT_NDO_XMIT feature is enabled by default, so when the step 2 command is exexcuted and packets have already been sent to eth0, the stmmac_xdp_xmit() starts running before the stmmac_xdp_set_prog() finishes. To resolve this issue, we disable the NETDEV_XDP_ACT_NDO_XMIT feature by default and turn on/off this feature when the bpf program is installed/uninstalled which just like the other ethernet drivers.

Holding the struct phy_device (phydev) lock is unnecessary when accessing phydev->interface in the PHY driver .config_init method, which is the only place that vsc85xx_rgmii_set_skews() is called from. The phy_modify_paged() function implements required MDIO bus level locking, which can not be achieved by a phydev lock.

2023-05-24net/mlx5e: Don't attach netdev profile while handling internal errorDmytro Linkin
As part of switchdev mode disablement, driver changes port netdevice profile from uplink to nic. If this process is triggered by health recovery flow (PCI reset, for ex.) profile attach would fail because all fw commands aborted when internal error flag is set. As a result, nic netdevice profile is not attached and driver fails to rollback to uplink profile, which leave driver in broken state and cause crash later. To handle broken state do netdevice profile initialization only instead of full attachment and release mdev resources on driver suspend as expected. Actual netdevice attachment is done during driver load.

2023-05-24net/mlx5: Fix post parse infra to only parse every action onceVlad Buslov
Caller of mlx5e_tc_act_post_parse() needs it to parse only the subset of actions starting after previous split and ending at the current action. However, that range is not provided as arguments and mlx5e_tc_act_post_parse() uses generic flow_action_for_each() that iterates over all flow actions. Not only this is redundant, it also causes a bug when mlx5e_tc_act->post_parse() callback is not idempotent since it will be called for every split. For example, ct action tc_act_post_parse_ct() callback obtains a reference to mlx5_ct_ft instance and calling it several times during parsing stage will cause reference counter imbalance. Fix the issue by providing a proper action range of the current split subset to mlx5e_tc_act_post_parse() and only calling mlx5e_tc_act->post_parse() for actions inside the subset range.

Don't query the firmware so many times (num rqs * num wqes * wqe frags) because it slows down linearly the interface creation time when the product is larger. Do it only once per mdev and store the result in mlx5e_param. Due to helper function being called from different files, move it to an appropriate location. Rename the function with a proper prefix and add a small cleanup. This fix applies only for legacy rq.
