Adds serdev_device_break_ctl() and an implementation for ttyport. This function simply calls the break_ctl in tty layer, which can assert a break signal over UART-TX line, if the tty and the underlying platform and UART peripheral supports this operation. Signed-off-by:

This replaces all instances of ENOTSUPP with EOPNOTSUPP since ENOTSUPP is not a standard error code. This will help maintain consistency in error codes when new serdev API's are added. Signed-off-by:

The Realtek RTL8723CS is a SDIO WiFi chip. It also contains a Bluetooth module which is connected via UART to the host. It shares lmp subversion with 8703B, so Realtek's userspace initialization tool (rtk_hciattach) differentiates varieties of RTL8723CS (CG, VF, XX) with RTL8703B using vendor's command to read chip type. Also this chip declares support for some features it doesn't support so add a quirk to indicate that these features are broken. Signed-off-by:

Some adapters (e.g. RTL8723CS) advertise that they have more than 2 pages for local ext features, but they don't support any features declared in these pages. RTL8723CS reports max_page = 2 and declares support for sync train and secure connection, but it responds with either garbage or with error in status on corresponding commands. Signed-off-by:

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>

Unbounded info messages in the pedit datapath can flood the printk ring buffer quite easily depending on the action created. As these messages are informational, usually printing some, not all, is enough to bring attention to the real issue. Reviewed-by:

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. I've reviewed vlan_insert_tag() and it does not *actually* depend on skb_mac_header(), so reword that to avoid the confusion. Signed-off-by:
