Currently, when we initiate disconnection, we will wait for the peer's reply unless when we are suspending, where we fire and forget the disconnect request. A similar case is when adapter is powering off. However, we still wait for the peer's reply in this case. Therefore, if the peer is unresponsive, the command will time out and the power off sequence will fail, causing "bluetooth powered on by itself" to users. This patch makes the host doesn't wait for the peer's reply when the disconnection reason is powering off. Signed-off-by:

Pedro Tammela says: ==================== net/sched: act_pedit: minor improvements This series aims to improve the code and usability of act_pedit for netlink users. Patches 1-2 improves error reporting for extended keys parsing with extack. Patch 3 checks the static offsets a priori on create/update. Currently, this is done at the datapath for both static and runtime offsets. Patch 4 removes a check from the datapath which is redundant since the netlink parsing validates the key types. Patch 5 changes the 'pr_info()' calls in the datapath to rate limited versions. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

The netlink parsing already validates the key 'htype'. Remove the datapath check as it's redundant. Reviewed-by:

Pedro Tammela authored
Static key offsets should always be on 32 bit boundaries. Validate them on create/update time for static offsets and move the datapath validation for runtime offsets only. iproute2 already errors out if a given offset and data size cannot be packed to a 32 bit boundary. This change will make sure users which create/update pedit instances directly via netlink also error out, instead of finding out when packets are traversing. Reviewed-by:

Vladimir Oltean says: ==================== Remove skb_mac_header() dependency in DSA xmit path Eric started working on removing skb_mac_header() assumptions from the networking xmit path, and I offered to help for DSA: https://lore.kernel.org/netdev/20230321164519.1286357-1-edumazet@google.com/ The majority of this patch set is a straightforward replacement of skb_mac_header() with skb->data (hidden either behind skb_eth_hdr(), or behind skb_vlan_eth_hdr()). The only patch which is more "interesting" is 9/9. Another potential caller of __skb_vlan_pop() on xmit (and therefore also of skb_mac_header()) is tcf_vlan_act(), but I haven't had the time to investigate that (enough to submit changes other than what's here). v1->v2: - 09/09: document the vlan_tci argument of vlan_remove_tag() in the kdoc v1 at: https://lore.kernel.org/netdev/20230322233823.1806736-1-vladimir.oltean@nxp.com/ Cc: Madalin Bucur <madalin.bucur@nxp.com> ==================== Signed-off-by:

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 6d1ccff6 ("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. Signed-off-by:

Once commit 6d1ccff6 ("net: reset mac header in dev_start_xmit()") will be reverted, it will no longer be true that skb->data points at skb_mac_header(skb) - since the skb->mac_header will not be set - so stop saying that, and just say that it points to the MAC header.

It appears that dpaa_enable_tx_csum() only calls skb_reset_mac_header() to get to the VLAN header using skb_mac_header(). We can use skb_vlan_eth_hdr() to get to the VLAN header based on skb->data directly. This avoids spending a few cycles to set skb->mac_header. Signed-off-by:

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. Signed-off-by:
