When the hci support is built-in, but mvmem is a loadable module, we get a link failure: drivers/bluetooth/hci_ll.o: In function `hci_ti_probe': hci_ll.c:(.text+0x226): undefined reference to `nvmem_cell_get' hci_ll.c:(.text+0x238): undefined reference to `nvmem_cell_read' hci_ll.c:(.text+0x244): undefined reference to `nvmem_cell_put' This adds another Kconfig dependency to enforce valid configurations.

This reverts commit fd865802. This commit causes a regression on some QCA ROME chips. The USB device reset happens in btusb_open(), hence firmware loading gets interrupted. Furthermore, this commit stops working after commit ("a0085f25 Bluetooth: btusb: driver to enable the usb-wakeup feature"). Reset-resume quirk only gets enabled in btusb_suspend() when it's not a wakeup source. If we really want to reset the USB device, we need to do it before btusb_open(). Let's handle it in drivers/usb/core/quirks.c.

This driver seeks to force the Bluetooth device on for the duration of 5 seconds when the Bluetooth device has woken the host and after a complete packet has been received. It does that by calling: pm_runtime_get(); pm_runtime_mark_last_busy(); pm_runtime_put_autosuspend(); The same can be achieved more succinctly with: pm_request_resume(); That's because after runtime resuming the device, rpm_resume() invokes pm_runtime_mark_last_busy() followed by rpm_idle(), which will cause the device to be suspended after expiration of the autosuspend_delay. No functional change intended. Cc: Frédéric Danis <frederic.danis.oss@gmail.com> Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device to the btusb blacklist and makes the kernel use the btqca module instead of btusb. The patch is necessary because, without it the 04ca:3015 device defaults to using the btusb driver, which makes the WIFI side of the QCA9377 board unusable (obtains 0 MBps in speedtest, when the 04ca:3015 bluetooth is used with an audio headset). /sys/kernel/debug/usb/devices: T: Bus=01 Lev=01 Prnt=01 Port=04 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 2.01 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=04ca ProdID=3015 Rev= 0.01 C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb E: Ad=81(I) Atr=03(Int.)

ASSERT_RTNL() macro is actual open-coded variant of WARN_ONCE() with two exceptions. First, it prints stack for multiple hits and not only once as WARN_ONCE() does. Second, the user can disable prints of WARN_ONCE by setting CONFIG_BUG to N. The multiple prints of dump stack are actually not needed, because calls without rtnl lock are programming errors and user can't do anything about them except to complain to the mailing list after first occurrence of such failure. The user who disabled BUG/WARN prints did it explicitly because by default in upstream kernel and distributions this option is enabled. It means that user doesn't want to see prints about missing locks too. This patch replaces open-coded variant in favor of already existing macro and change error prints to be once only.

Sven Eckelmann says: ==================== flow_dissector: Provide basic batman-adv unicast handling we are currently starting to use batman-adv as mesh protocol on multicore embedded devices. These usually don't have a lot of CPU power per core but are reasonable fast when using multiple cores. It was noticed that sending was working very well but receiving was basically only using on CPU core per neighbor. The reason for that is format of the (normal) incoming packet: +--------------------+ | ip(v6)hdr | +--------------------+ | inner ethhdr | +--------------------+ | batadv unicast hdr | +--------------------+ | outer ethhdr | +--------------------+ The flow dissector will therefore stop after parsing the outer ethernet header and will not parse the actual ipv(4|6)/... header of the packet. Our assumption was now that it would help us to add minimal support to the flow dissector to jump over the batman-adv unicast and inner ethernet header (like in gre ETH_P_TEB). The patch was implemented in a slightly hacky way [1] and the results looked quite promising. I didn't get any feedback how the files should actually be named. So I am now just using the names from RFC v3 The discussion of the RFC v3 can be found in the related patches of https://patchwork.ozlabs.org/cover/849345/ The discussion of the RFC v2 can be found in the related patches of https://patchwork.ozlabs.org/cover/844783/ Changes in v4: ============== * added patch to change the u8/u16 to __u8/__u16 in include/uapi/linux/batadv_packet.h - requested by Willem de Bruijn <willemdebruijn.kernel@gmail.com> Changes in v3: ============== * removed change of uapi/linux/batman_adv.h to uapi/linux/batadv_genl.h - requested by Willem de Bruijn <willemdebruijn.kernel@gmail.com> * removed naming fixes for enums/defines in uapi/linux/batadv_genl.h - requested by Willem de Bruijn <willemdebruijn.kernel@gmail.com> * renamed uapi/linux/batadv.h to uapi/linux/batadv_packet.h * moved batadv dissector functionality in own function - requested by Tom Herbert <tom@herbertland.com> * added support for flags FLOW_DISSECTOR_F_STOP_AT_ENCAP and FLOW_DIS_ENCAPSULATION - requested by Willem de Bruijn <willemdebruijn.kernel@gmail.com> Changes in v2: ============== * removed the batman-adv unicast packet header definition from flow_dissector.c * moved the batman-adv packet.h/uapi headers around to provide the correct definitions to flow_dissector.c ==================== Signed-off-by: David S.

The batman-adv unicast packets contain a full layer 2 frame in encapsulated form. The flow dissector must therefore be able to parse the batman-adv unicast header to reach the layer 2+3 information. +--------------------+ | ip(v6)hdr | +--------------------+ | inner ethhdr | +--------------------+ | batadv unicast hdr | +--------------------+ | outer ethhdr | +--------------------+ The obtained information from the upper layer can then be used by RPS to schedule the processing on separate cores. This allows better distribution of multiple flows from the same neighbor to different cores.

The header file is used by different userspace programs to inject packets or to decode sniffed packets. It should therefore be available to them as userspace header.

Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new count in a field of MC_CMD_GET_CAPABILITIES_V4. This also means that the end generation count moves (it is, as before, the last 64 bits of the DMA buffer, but that is no longer MC_CMD_MAC_GENERATION_END). So read num_mac_stats from the GET_CAPABILITIES response, if present; otherwise assume MC_CMD_MAC_NSTATS; and always use num_mac_stats - 1 rather than MC_CMD_MAC_GENERATION_END.

Call skb_zerocopy_clone after skb_orphan_frags, to avoid duplicate calls to skb_uarg(skb)->callback for the same data. skb_zerocopy_clone associates skb_shinfo(skb)->uarg from frag_skb with each segment. This is only safe for uargs that do refcounting, which is those that pass skb_orphan_frags without dropping their shared frags. For others, skb_orphan_frags drops the user frags and sets the uarg to NULL, after which sock_zerocopy_clone has no effect. Qemu hangs were reported due to duplicate vhost_net_zerocopy_callback calls for the same data causing the vhost_net_ubuf_ref_>refcount to drop below zero.

This patch adds the necessary RGMII_[RX|TX]ID mode code to handle such PHYs with the emac driver. Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David S.

The ibm_emac driver predates the PHY_INTERFACE_MODE_* enums by a few years. And while the driver has been retrofitted to use the PHYLIB, the old definitions have stuck around to this day. This patch replaces all occurences of PHY_MODE_* with the respective equivalent PHY_INTERFACE_MODE_* enum. And finally, it purges the old macros for good.

phy_modes() in the common phy.h already defines the same phy mode names in lower case. The deleted rgmii_mode_name() is used only in one place and for a "notice-level" printk. Hence, it will not be missed. Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

sysctl.ip6.auto_flowlabels is default 1. In our hosts, we set it to 2. If sockopt doesn't set autoflowlabel, outcome packets from the hosts are supposed to not include flowlabel. This is true for normal packet, but not for reset packet. The reason is ipv6_pinfo.autoflowlabel is set in sock creation. Later if we change sysctl.ip6.auto_flowlabels, the ipv6_pinfo.autoflowlabel isn't changed, so the sock will keep the old behavior in terms of auto flowlabel. Reset packet is suffering from this problem, because reset packet is sent from a special control socket, which is created at boot time. Since sysctl.ipv6.auto_flowlabels is 1 by default, the control socket will always have its ipv6_pinfo.autoflowlabel set, even after user set sysctl.ipv6.auto_flowlabels to 1, so reset packset will always have flowlabel. Normal sock created before sysctl setting suffers from the same issue. We can't even turn off autoflowlabel unless we kill all socks in the hosts. To fix this, if IPV6_AUTOFLOWLABEL sockopt is used, we use the autoflowlabel setting from user, otherwise we always call ip6_default_np_autolabel() which has the new settings of sysctl. Note, this changes behavior a little bit. Before commit 42240901 (ipv6: Implement different admin modes for automatic flow labels), the autoflowlabel behavior of a sock isn't sticky, eg, if sysctl changes, existing connection will change autoflowlabel behavior. After that commit, autoflowlabel behavior is sticky in the whole life of the sock. With this patch, the behavior isn't sticky again.

skb_vlan_pop() expects skb->protocol to be a valid TPID for double tagged frames. So set skb->protocol to the TPID and let skb_vlan_pop() shift the true ethertype into position for us.

Alexander Aring says: ==================== net: sched: sch: introduce extack support this patch series basically add support for extack in common qdisc handling. Additional it adds extack pointer to common qdisc callback handling this offers per qdisc implementation to setting the extack message for each failure over netlink. The extack message will be set deeper in qdisc functions but going not deeper as net core api. For qdisc module callback handling, the extack will not be set. This will be part of per qdisc extack handling. I also want to prepare patches to handle extack per qdisc module... so there will come a lot of more patches, just cut them down to make it reviewable. There are some above 80-chars width warnings, which I ignore because it looks more ugly otherwise. This patch-series based on patches by David Ahern which gave me some hints how to deal with extack support. Cc: David Ahern <dsahern@gmail.com> changes since v4: - rebase on current net-next/master - fix several typos (also David Ahren to Ahern, I am sorry) - Add acked by Jamal changes since v3: - remove patch 2/2 lib: nlattr: set extack msg if validate_nla fails since David Ahern has a better solution - Remove check on net admin permission since -EPERM indicates it already - Change rtab to "rate table" - this is what it's stands for - Fix cbs *not* support messages - Fix tcf block error message for allocation, allocation will be still there because there are multiple places which returns -ENOMEM - Finnally also took care about sch_atm, sorry somehow I forgot this one and I hope I didn't forgot any sch implementation to add new callback parameters changes since v2: - add fix coding style patch to catch all checkpatch warnings - add patch for setting netlink extack msg if validate_nla fails - changes in handle generic qdisc errors - remove NL_SET_ERR_MSG from memory allocation errors - remove NL_SET_ERR_MSG from device not found - change STAB to table size - add various new patches to add extack support for common TC functions like qdisc_get_rtab, tcf_block_get, qdisc_alloc and qdisc_create_dflt - users which are interessted in the detailed error messages can assign extack, otherwise NULL. - Add sch_cbq as example for qdisc_ops callback: init, qdisc_class_ops callbacks: change and graft - Add sch_cbs as example for qdisc_ops callback: change - Add sch_drr as example for qdisc_class ops callbacks: tcf_block ==================== Signed-off-by: David S.

This patch adds extack support for the drr qdisc implementation by adding NL_SET_ERR_MSG in validation of user input. Also it serves to illustrate a use case of how the infrastructure ops api changes are to be used by individual qdiscs.
