Because hci_cmd_sync_queue can no longer queue work while HCI_RUNNING is not set it cannot be used to power on adapters so instead hci_cmd_sync_submit is introduced which bypass the HCI_RUNNING check, so it behaves like the old implementation.

2023-04-23Bluetooth: Add support for hci devcoredumpAbhishek Pandit-Subedi
Add devcoredump APIs to hci core so that drivers only have to provide the dump skbs instead of managing the synchronization and timeouts. The devcoredump APIs should be used in the following manner: - hci_devcoredump_init is called to allocate the dump. - hci_devcoredump_append is called to append any skbs with dump data OR hci_devcoredump_append_pattern is called to insert a pattern. - hci_devcoredump_complete is called when all dump packets have been sent OR hci_devcoredump_abort is called to indicate an error and cancel an ongoing dump collection. The high level APIs just prepare some skbs with the appropriate data and queue it for the dump to process. Packets part of the crashdump can be intercepted in the driver in interrupt context and forwarded directly to the devcoredump APIs. Internally, there are 5 states for the dump: idle, active, complete, abort and timeout. A devcoredump will only be in active state after it has been initialized. Once active, it accepts data to be appended, patterns to be inserted (i.e. memset) and a completion event or an abort event to generate a devcoredump. The timeout is initialized at the same time the dump is initialized (defaulting to 10s) and will be cleared either when the timeout occurs or the dump is complete or aborted.

2023-04-23net: dsa: tag_ocelot: call only the relevant portion of __skb_vlan_pop() on TXVladimir Oltean
ocelot_xmit_get_vlan_info() calls __skb_vlan_pop() as the most appropriate helper I could find which strips away a VLAN header. That's all I need it to do, but __skb_vlan_pop() has more logic, which will become incompatible with the future revert of commit 6d1ccff62780 ("net: reset mac header in dev_start_xmit()"). Namely, it performs a sanity check on skb_mac_header(), which will stop being set after the above revert, so it will return an error instead of removing the VLAN tag. ocelot_xmit_get_vlan_info() gets called in 2 circumstances: (1) the port is under a VLAN-aware bridge and the bridge sends VLAN-tagged packets (2) the port is under a VLAN-aware bridge and somebody else (an 8021q upper) sends VLAN-tagged packets (using a VID that isn't in the bridge vlan tables) In case (1), there is actually no bug to defend against, because br_dev_xmit() calls skb_reset_mac_header() and things continue to work. However, in case (2), illustrated using the commands below, it can be seen that our intervention is needed, since __skb_vlan_pop() complains: $ ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up $ ip link set $eth master br0 && ip link set $eth up $ ip link add link $eth name $eth.100 type vlan id 100 && ip link set $eth.100 up $ ip addr add 192.168.100.1/24 dev $eth.100 I could fend off the checks in __skb_vlan_pop() with some skb_mac_header_was_set() calls, but seeing how few callers of __skb_vlan_pop() there are from TX paths, that seems rather unproductive. As an alternative solution, extract the bare minimum logic to strip a VLAN header, and move it to a new helper named vlan_remove_tag(), close to the definition of vlan_insert_tag(). Document it appropriately and make ocelot_xmit_get_vlan_info() call this smaller helper instead. Seeing that it doesn't appear illegal to test skb->protocol in the TX path, I guess it would be a good for vlan_remove_tag() to also absorb the vlan_set_encap_proto() function call.

2023-04-23net: vlan: introduce skb_vlan_eth_hdr()Vladimir Oltean
Similar to skb_eth_hdr() introduced in commit 96cc4b69581d ("macvlan: do not assume mac_header is set in macvlan_broadcast()"), let's introduce a skb_vlan_eth_hdr() helper which can be used in TX-only code paths to get to the VLAN header based on skb->data rather than based on the skb_mac_header(skb). We also consolidate the drivers that dereference skb->data to go through this helper.

2023-04-23net: vlan: don't adjust MAC header in __vlan_insert_inner_tag() unless setVladimir Oltean
This is a preparatory change for the deletion of skb_reset_mac_header(skb) from __dev_queue_xmit(). After that deletion, skb_mac_header(skb) will no longer be set in TX paths, from which __vlan_insert_inner_tag() can still be called (perhaps indirectly). If we don't make this change, then an unset MAC header (equal to ~0U) will become set after the adjustment with VLAN_HLEN.

We use napi_threaded_poll() in order to reduce our softirq dependency. We can add a followup of 821eba962d95 ("net: optimize napi_schedule_rps()") to further remove the need of firing NET_RX_SOFTIRQ whenever RPS/RFS are used.

Firstly, fix the distribution between public and private headers. Otherwise, some of the already public macros wouldn't actually work, and the SNDRV_EMU10K1_IOCTL_DBG_READ result for Audigy would be useless. Secondly, add condition code registers for Audigy. These are just aliases for selected constant registers, and thus are generation- specific. At least A_CC_REG_ZERO is actually correct ... Finally, shuffle around some defines to more logical places while at it, and fix up some more comments.

Firstly, remove the FXWC_* defines - the comment on FXWC implies that the relevant defines are the (A_)EXTOUT_* ones. It's unclear where this came from - it was in the initial ALSA import, but neither the driver from Creative nor kX-project have these defines. Secondly, remove A_HR, which made plain no sense (was unused, and clashed with FXRT). Amends commit cbb7d8f9b7b ("emu10k1: Update registers defines for the Audigy 2/emu10k2.5").

2023-04-22cxl/mbox: Deprecate poison commandsDan Williams
The CXL subsystem is adding formal mechanisms for managing device poison. Minimize the maintenance burden going forward, and maximize the investment in common tooling by deprecating direct user access to poison commands outside of CXL_MEM_RAW_COMMANDS debug scenarios. A new cxl_deprecated_commands[] list is created for querying which command ids defined in previous kernels are now deprecated. CXL Media and Poison Management commands, opcodes 0x43XX, defined in CXL 3.0 Spec, Table 8-93 are deprecated with one exception: Get Scan Media Capabilities. Keep Get Scan Media Capabilities as it simply provides information and has no impact on the device state. Effectively all of the commands defined in: commit 87815ee9d006 ("cxl/pci: Add media provisioning required commands") ...were defined prematurely and should have waited until the kernel implementation was decided. To my knowledge there are no shipping devices with poison support and no known tools that would regress with this change.

2023-04-22ALSA: emu10k1: fix snd_emu1010_fpga_read() input masking for rev2 cardsOswald Buddenhagen
Unlike the Alice2 chips used on 1st generation E-MU cards, the Tina/Tina2 chips used on the 2nd gen cards have only six GPIN pins, which means that we need to use a smaller mask. Failure to do so would falsify the read data if the FPGA tried to raise an IRQ right at that moment. This wasn't a problem so far, as we didn't actually enable FPGA IRQs, but that's going to change soon.

2023-04-22rxrpc: Fix potential race in error handling in afs_make_call()David Howells
If the rxrpc call set up by afs_make_call() receives an error whilst it is transmitting the request, there's the possibility that it may get to the point the rxrpc call is ended (after the error_kill_call label) just as the call is queued for async processing. This could manifest itself as call->rxcall being seen as NULL in afs_deliver_to_call() when it tries to lock the call. Fix this by splitting rxrpc_kernel_end_call() into a function to shut down an rxrpc call and a function to release the caller's reference and calling the latter only when we get to afs_put_call().
