All 32-bit operations are implemented natively by the JIT, -except if the CPU lacks ll/sc instructions. - -Register mapping -================ -All 64-bit eBPF registers are mapped to native 32-bit MIPS register pairs, -and does not use any stack scratch space for register swapping. This means -that all eBPF register data is kept in CPU registers all the time, and -this simplifies the register management a lot.

The MIPS branch offset field is 18 bits, in bytes, -which is equivalent to the eBPF 16-bit instruction offset. However, since -the JIT may emit more than one CPU instruction per eBPF instruction, the -field width may overflow. If that happens, the JIT converts the long -conditional jump to a short PC-relative branch with the condition -inverted, jumping over a long unconditional absolute jmp (j). - -This conversion will change the instruction offset mapping used for jumps, -and may in turn result in more branch offset overflows. The JIT therefore -dry-runs the translation until no more branches are converted and the -offsets do not change anymore. There is an upper bound on this of course, -and if the JIT hits that limit, the last two iterations are run with all -branches being converted. - -Tail call count -=============== -The current tail call count is stored in the 16-byte area of the caller's -stack frame that is reserved for the callee in the o32 ABI. The value is -initialized in the prologue, and propagated to the tail-callee by skipping -the initialization instructions when emitting the tail call. - -Signed-off-by: Johan Almbladh <johan.almbladh@anyfinetworks.com> ---- - create mode 100644 arch/mips/net/bpf_jit_comp.c - create mode 100644 arch/mips/net/bpf_jit_comp.h - create mode 100644 arch/mips/net/bpf_jit_comp32.c - ---- a/arch/mips/net/Makefile -+++ b/arch/mips/net/Makefile -@@ -2,4 +2,9 @@ - # MIPS networking code - - obj-$(CONFIG_MIPS_CBPF_JIT) += bpf_jit.o bpf_jit_asm.o --obj-$(CONFIG_MIPS_EBPF_JIT) += ebpf_jit.o -+ -+ifeq ($(CONFIG_32BIT),y) -+ obj-$(CONFIG_MIPS_EBPF_JIT) += bpf_jit_comp.o bpf_jit_comp32.o -+else -+ obj-$(CONFIG_MIPS_EBPF_JIT) += ebpf_jit.o -+endif ---- /dev/null -+++ b/arch/mips/net/bpf_jit_comp.c -@@ -0,0 +1,1020 @@ -+// SPDX-License-Identifier: GPL-2.0-only -+/* -+ * Just-In-Time compiler for eBPF bytecode on MIPS. -+ * Implementation of JIT functions common to 32-bit and 64-bit CPUs. -+ * -+ * Copyright (c) 2021 Anyfi Networks AB. -+ * Author: Johan Almbladh <johan.almbladh@gmail.com> -+ * -+ * Based on code and ideas from -+ * Copyright (c) 2017 Cavium, Inc. -+ * Copyright (c) 2017 Shubham Bansal <illusionist.neo@gmail.com> -+ * Copyright (c) 2011 Mircea Gherzan <mgherzan@gmail.com> -+ */ -+ -+/* -+ * Code overview -+ * ============= -+ * -+ * - bpf_jit_comp.h -+ * Common definitions and utilities. -+ * -+ * - bpf_jit_comp.c -+ * Implementation of JIT top-level logic and exported JIT API functions. -+ * Implementation of internal operations shared by 32-bit and 64-bit code. -+ * JMP and ALU JIT control code, register control code, shared ALU and -+ * JMP/JMP32 JIT operations. -+ * -+ * - bpf_jit_comp32.c -+ * Implementation of functions to JIT prologue, epilogue and a single eBPF -+ * instruction for 32-bit MIPS CPUs. The functions use shared operations -+ * where possible, and implement the rest for 32-bit MIPS such as ALU64 -+ * operations. -+ * -+ * - bpf_jit_comp64.c -+ * Ditto, for 64-bit MIPS CPUs. -+ * -+ * Zero and sign extension -+ * ======================== -+ * 32-bit MIPS instructions on 64-bit MIPS registers use sign extension, -+ * but the eBPF instruction set mandates zero extension. We let the verifier -+ * insert explicit zero-extensions after 32-bit ALU operations, both for -+ * 32-bit and 64-bit MIPS JITs. Conditional JMP32 operations on 64-bit MIPs -+ * are JITed with sign extensions inserted when so expected. -+ * -+ * ALU operations -+ * ============== -+ * ALU operations on 32/64-bit MIPS and ALU64 operations on 64-bit MIPS are -+ * JITed in the following steps. ALU64 operations on 32-bit MIPS are more -+ * complicated and therefore only processed by special implementations in -+ * step (3). -+ * -+ * 1) valid_alu_i: -+ * Determine if an immediate operation can be emitted as such, or if -+ * we must fall back to the register version. -+ * -+ * 2) rewrite_alu_i: -+ * Convert BPF operation and immediate value to a canonical form for -+ * JITing. In some degenerate cases this form may be a no-op. -+ * -+ * 3) emit_alu_{i,i64,r,64}: -+ * Emit instructions for an ALU or ALU64 immediate or register operation. -+ * -+ * JMP operations -+ * ============== -+ * JMP and JMP32 operations require an JIT instruction offset table for -+ * translating the jump offset. This table is computed by dry-running the -+ * JIT without actually emitting anything. However, the computed PC-relative -+ * offset may overflow the 18-bit offset field width of the native MIPS -+ * branch instruction. In such cases, the long jump is converted into the -+ * following sequence. -+ * -+ * <branch> !<cond> +2 Inverted PC-relative branch -+ * nop Delay slot -+ * j <offset> Unconditional absolute long jump -+ * nop Delay slot -+ * -+ * Since this converted sequence alters the offset table, all offsets must -+ * be re-calculated. This may in turn trigger new branch conversions, so -+ * the process is repeated until no further changes are made. Normally it -+ * completes in 1-2 iterations. If JIT_MAX_ITERATIONS should reached, we -+ * fall back to converting every remaining jump operation. The branch -+ * conversion is independent of how the JMP or JMP32 condition is JITed. -+ * -+ * JMP32 and JMP operations are JITed as follows. -+ * -+ * 1) setup_jmp_{i,r}: -+ * Convert jump conditional and offset into a form that can be JITed. -+ * This form may be a no-op, a canonical form, or an inverted PC-relative -+ * jump if branch conversion is necessary. -+ * -+ * 2) valid_jmp_i: -+ * Determine if an immediate operations can be emitted as such, or if -+ * we must fall back to the register version. Applies to JMP32 for 32-bit -+ * MIPS, and both JMP and JMP32 for 64-bit MIPS. -+ * -+ * 3) emit_jmp_{i,i64,r,r64}: -+ * Emit instructions for an JMP or JMP32 immediate or register operation. -+ * -+ * 4) finish_jmp_{i,r}: -+ * Emit any instructions needed to finish the jump.

Also as a remark we cannot assume that the FIN or RST packet - is hitting flow table teardown as the packet might get bumped to the - slow path in nftables. - -This patch resets IPS_OFFLOAD_BIT from flow_offload_teardown(), so -conntrack handles the tcp rst/fin packet which triggers the CLOSE/FIN -state transition. - -Moreover, teturn the connection's ownership to conntrack upon teardown -by clearing the offload flag and fixing the established timeout value. -The flow table GC thread will asynchonrnously free the flow table and -hardware offload entries. - -Before this patch, the IPS_OFFLOAD_BIT remained set for expired flows on -which is also misleading since the flow is back to classic conntrack -path. - -If nf_ct_delete() removes the entry from the conntrack table, then it -calls nf_ct_put() which decrements the refcnt. This is not a problem -because the flowtable holds a reference to the conntrack object from -flow_offload_alloc() path which is released via flow_offload_free(). - -This patch also updates nft_flow_offload to skip packets in SYN_RECV -state. Since we might miss or bump packets to slow path, we do not know -what will happen there while we are still in SYN_RECV, this patch -postpones offload up to the next packet which also aligns to the -existing behaviour in tc-ct. - -flow_offload_teardown() does not reset the existing tcp state from -flow_offload_fixup_tcp() to ESTABLISHED anymore, packets bump to slow -path might have already update the state to CLOSE/FIN. - -Joint work with Oz and Sven. - -Fixes: 1e5b2471bcc4 ("netfilter: nf_flow_table: teardown flow timeout race") -Signed-off-by: Oz Shlomo <ozsh@nvidia.com> -Signed-off-by: Sven Auhagen <sven.auhagen@voleatech.de> -Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> -Signed-off-by: Sasha Levin <sashal@kernel.org> ---- - net/netfilter/nf_flow_table_core.c | 33 +++++++----------------------- - net/netfilter/nft_flow_offload.c | 3 ++- - 2 files changed, 9 insertions(+), 27 deletions(-) - ---- a/net/netfilter/nf_flow_table_core.c -+++ b/net/netfilter/nf_flow_table_core.c -@@ -173,12 +173,11 @@ EXPORT_SYMBOL_GPL(flow_offload_route_ini - - static void flow_offload_fixup_tcp(struct ip_ct_tcp *tcp) - { -- tcp->state = TCP_CONNTRACK_ESTABLISHED;

Instead, with one small change, -the bridge could notify of the address deletion from the old port, in a -symmetrical manner with how it did for the insertion. Then the switchdev -driver would not be required to monitor learn/forget events for its own -ports. It could just delete the rule towards the control interface upon -bridge entry migration.

The generic solution is not -to assume that hardware learning can be enabled somehow, but to listen -to more bridge learning events. It turns out that the bridge driver does -learn in software from all inbound frames, in __br_handle_local_finish. -A proper SWITCHDEV_FDB_ADD_TO_DEVICE notification is emitted for the -addresses serviced by the bridge on 'foreign' interfaces. The software -bridge also does the right thing on migration, by notifying that the old -entry is deleted, so that does not need to be special-cased in DSA. When -it is deleted, we just need to delete our static FDB entry towards the -CPU too, and wait. - -The problem is that DSA currently only cares about SWITCHDEV_FDB_ADD_TO_DEVICE -events received on its own interfaces, such as static FDB entries. - -Luckily we can change that, and DSA can listen to all switchdev FDB -add/del events in the system and figure out if those events were emitted -by a bridge that spans at least one of DSA's own ports. In case that is -true, DSA will also offload that address towards its own CPU port, in -the eventuality that there might be bridge clients attached to the DSA -switch who want to talk to the station connected to the foreign -interface. - -In terms of implementation, we need to keep the fdb_info->added_by_user -check for the case where the switchdev event was targeted directly at a -DSA switch port. But we don't need to look at that flag for snooped -events. So the check is currently too late, we need to move it earlier. -This also simplifies the code a bit, since we avoid uselessly allocating -and freeing switchdev_work. - -We could probably do some improvements in the future. For example, -multi-bridge support is rudimentary at the moment. If there are two -bridges spanning a DSA switch's ports, and both of them need to service -the same MAC address, then what will happen is that the migration of one -of those stations will trigger the deletion of the FDB entry from the -CPU port while it is still used by other bridge. That could be improved -with reference counting but is left for another time. - -This behavior needs to be enabled at driver level by setting -ds->assisted_learning_on_cpu_port = true. This is because we don't want -to inflict a potential performance penalty (accesses through -MDIO/I2C/SPI are expensive) to hardware that really doesn't need it -because address learning on the CPU port works there. - -Reported-by: DENG Qingfang <dqfext@gmail.com> -Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> -Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> -Reviewed-by: Andrew Lunn <andrew@lunn.ch> -Signed-off-by: Jakub Kicinski <kuba@kernel.org> ---- - include/net/dsa.h | 5 +++++ - net/dsa/slave.c | 66 +++++++++++++++++++++++++++++++++++++++++++++---------- - 2 files changed, 60 insertions(+), 11 deletions(-) - ---- a/include/net/dsa.h -+++ b/include/net/dsa.h -@@ -317,6 +317,11 @@ struct dsa_switch { - */ - bool untag_bridge_pvid; - -+ /* Let DSA manage the FDB entries towards the CPU, based on the -+ * software bridge database. -+ */ -+ bool assisted_learning_on_cpu_port; -+ - /* In case vlan_filtering_is_global is set, the VLAN awareness state - * should be retrieved from here and not from the per-port settings. - */ ---- a/net/dsa/slave.c -+++ b/net/dsa/slave.c -@@ -2149,6 +2149,28 @@ static void dsa_slave_switchdev_event_wo - dev_put(dp->slave); - } - -+static int dsa_lower_dev_walk(struct net_device *lower_dev, -+ struct netdev_nested_priv *priv) -+{ -+ if (dsa_slave_dev_check(lower_dev)) { -+ priv->data = (void *)netdev_priv(lower_dev); -+ return 1; -+ } -+ -+ return 0; -+} -+ -+static struct dsa_slave_priv *dsa_slave_dev_lower_find(struct net_device *dev) -+{ -+ struct netdev_nested_priv priv = { -+ .data = NULL, -+ }; -+ -+ netdev_walk_all_lower_dev_rcu(dev, dsa_lower_dev_walk, &priv); -+ -+ return (struct dsa_slave_priv *)priv.data; -+} -+ - /* Called under rcu_read_lock() */ - static int dsa_slave_switchdev_event(struct notifier_block *unused, - unsigned long event, void *ptr) -@@ -2167,10 +2189,37 @@ static int dsa_slave_switchdev_event(str - return notifier_from_errno(err); - case SWITCHDEV_FDB_ADD_TO_DEVICE: - case SWITCHDEV_FDB_DEL_TO_DEVICE: -- if (!dsa_slave_dev_check(dev)) -- return NOTIFY_DONE; -+ fdb_info = ptr; -+ -+ if (dsa_slave_dev_check(dev)) { -+ if (!fdb_info->added_by_user) -+ return NOTIFY_OK; -+ -+ dp = dsa_slave_to_port(dev); -+ } else { -+ /* Snoop addresses learnt on foreign interfaces -+ * bridged with us, for switches that don't -+ * automatically learn SA from CPU-injected traffic -+ */ -+ struct net_device *br_dev; -+ struct dsa_slave_priv *p; -+ -+ br_dev = netdev_master_upper_dev_get_rcu(dev); -+ if (!br_dev) -+ return NOTIFY_DONE; -+ -+ if (!netif_is_bridge_master(br_dev)) -+ return NOTIFY_DONE; -+ -+ p = dsa_slave_dev_lower_find(br_dev); -+ if (!p) -+ return NOTIFY_DONE; - -- dp = dsa_slave_to_port(dev); -+ dp = p->dp->cpu_dp; -+ -+ if (!dp->ds->assisted_learning_on_cpu_port) -+ return NOTIFY_DONE; -+ } - - if (!dp->ds->ops->port_fdb_add || !dp->ds->ops->port_fdb_del) - return NOTIFY_DONE; -@@ -2185,18 +2234,13 @@ static int dsa_slave_switchdev_event(str - switchdev_work->port = dp->index; - switchdev_work->event = event; - -- fdb_info = ptr; -- -- if (!fdb_info->added_by_user) { -- kfree(switchdev_work); -- return NOTIFY_OK; -- } -- - ether_addr_copy(switchdev_work->addr, - fdb_info->addr); - switchdev_work->vid = fdb_info->vid; - -- dev_hold(dev); -+ /* Hold a reference on the slave for dsa_fdb_offload_notify */ -+ if (dsa_is_user_port(dp->ds, dp->index)) -+ dev_hold(dev); - dsa_schedule_work(&switchdev_work->work); - break; - default: diff --git a/target/linux/generic/backport-5.10/729-v5.14-net-phy-at803x-mask-1000-Base-X-link-mode.patch b/target/linux/generic/backport-5.10/729-v5.14-net-phy-at803x-mask-1000-Base-X-link-mode.patch deleted file mode 100644 index a977db0b6c..0000000000 --- a/target/linux/generic/backport-5.10/729-v5.14-net-phy-at803x-mask-1000-Base-X-link-mode.patch +++ /dev/null @@ -1,68 +0,0 @@ -From b856150c8098f12996ee81c3ab2a65adbaeeb3ec Mon Sep 17 00:00:00 2001 -From: David Bauer <mail@david-bauer.net> -Date: Sun, 27 Jun 2021 12:16:07 +0200 -Subject: [PATCH] net: phy: at803x: mask 1000 Base-X link mode - -AR8031/AR8033 have different status registers for copper -and fiber operation.

The trick for now, was to allocate a -device resource managed buffer which is then returned.

Thus we can just test its return code. But we have to be -careful if there are still other sources for the MAC address before the -of_get_mac_address(). In this case we have to keep the -is_valid_ether_addr() call. - -The following coccinelle patch was used to convert common cases to the -new style. Afterwards, I've manually gone over the drivers and fixed the -return code variable: either used a new one or if one was already -available use that.

the bridge - -DSA has gained the recent ability to deal gracefully with upper -interfaces it cannot offload, such as the bridge, bonding or team -drivers. When such uppers exist, the ports are still in standalone mode -as far as the hardware is concerned. - -But when we deliver packets to the software bridge in order for that to -do the forwarding, there is an unpleasant surprise in that the bridge -will refuse to forward them. This is because we unconditionally set -skb->offload_fwd_mark = true, meaning that the bridge thinks the frames -were already forwarded in hardware by us. - -Since dp->bridge_dev is populated only when there is hardware offload -for it, but not in the software fallback case, let's introduce a new -helper that can be called from the tagger data path which sets the -skb->offload_fwd_mark accordingly to zero when there is no hardware -offload for bridging. This lets the bridge forward packets back to other -interfaces of our switch, if needed. - -Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> -Reviewed-by: Tobias Waldekranz <tobias@waldekranz.com> -Signed-off-by: David S.

Commit 2ea7a679ca2a -("net: dsa: Don't add vlans when vlan filtering is disabled") noticed -some issues with VLAN and decided the best way to deal with them was to -make the DSA core ignore VLANs added by the bridge while VLAN awareness -is turned off. Those issues were never explained, just presented as -"at least one corner case". - -That approach had problems of its own, presented by -commit 54a0ed0df496 ("net: dsa: provide an option for drivers to always -receive bridge VLANs") for the DSA core, followed by -commit 1fb74191988f ("net: dsa: mv88e6xxx: fix vlan setup") which -applied ds->configure_vlan_while_not_filtering = true for mv88e6xxx in -particular. - -We still don't know what corner case Andrew saw when he wrote -commit 2ea7a679ca2a ("net: dsa: Don't add vlans when vlan filtering is -disabled"), but Tobias now reports that when we use TX forwarding -offload, pinging an external station from the bridge device is broken if -the front-facing DSA user port has flooding turned off. The full -description is in the link below, but for short, when a mv88e6xxx port -is under a VLAN-unaware bridge, it inherits that bridge's pvid. -So packets ingressing a user port will be classified to e.g. VID 1 -(assuming that value for the bridge_default_pvid), whereas when -tag_dsa.c xmits towards a user port, it always sends packets using a VID -of 0 if that port is standalone or under a VLAN-unaware bridge - or at -least it did so prior to commit d82f8ab0d874 ("net: dsa: tag_dsa: -offload the bridge forwarding process"). - -In any case, when there is a conversation between the CPU and a station -connected to a user port, the station's MAC address is learned in VID 1 -but the CPU tries to transmit through VID 0. The packets reach the -intended station, but via flooding and not by virtue of matching the -existing ATU entry. - -DSA has established (and enforced in other drivers: sja1105, felix, -mt7530) that a VLAN-unaware port should use a private pvid, and not -inherit the one from the bridge. The bridge's pvid should only be -inherited when that bridge is VLAN-aware, so all state transitions need -to be handled. On the other hand, all bridge VLANs should sit in the VTU -starting with the moment when the bridge offloads them via switchdev, -they are just not used. - -This solves the problem that Tobias sees because packets ingressing on -VLAN-unaware user ports now get classified to VID 0, which is also the -VID used by tag_dsa.c on xmit. - -Fixes: d82f8ab0d874 ("net: dsa: tag_dsa: offload the bridge forwarding process") -Link: https://patchwork.kernel.org/project/netdevbpf/patch/20211003222312.284175-2-vladimir.oltean@nxp.com/#24491503 -Reported-by: Tobias Waldekranz <tobias@waldekranz.com> -Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> -Signed-off-by: Jakub Kicinski <kuba@kernel.org> ---- - drivers/net/dsa/mv88e6xxx/chip.c | 56 +++++++++++++++++++++++++++++--- - drivers/net/dsa/mv88e6xxx/chip.h | 6 ++++ - drivers/net/dsa/mv88e6xxx/port.c | 21 ++++++++++++ - drivers/net/dsa/mv88e6xxx/port.h | 2 ++ - 4 files changed, 81 insertions(+), 4 deletions(-) - ---- a/drivers/net/dsa/mv88e6xxx/chip.c -+++ b/drivers/net/dsa/mv88e6xxx/chip.c -@@ -1590,6 +1590,26 @@ static int mv88e6xxx_port_check_hw_vlan( - return 0; - } - -+static int mv88e6xxx_port_commit_pvid(struct mv88e6xxx_chip *chip, int port) -+{ -+ struct dsa_port *dp = dsa_to_port(chip->ds, port); -+ struct mv88e6xxx_port *p = &chip->ports[port]; -+ bool drop_untagged = false; -+ u16 pvid = 0; -+ int err; -+ -+ if (dp->bridge_dev && br_vlan_enabled(dp->bridge_dev)) { -+ pvid = p->bridge_pvid.vid; -+ drop_untagged = !p->bridge_pvid.valid; -+ } -+ -+ err = mv88e6xxx_port_set_pvid(chip, port, pvid); -+ if (err) -+ return err; -+ -+ return mv88e6xxx_port_drop_untagged(chip, port, drop_untagged); -+} -+ - static int mv88e6xxx_port_vlan_filtering(struct dsa_switch *ds, int port, - bool vlan_filtering, - struct switchdev_trans *trans) -@@ -1603,7 +1623,16 @@ static int mv88e6xxx_port_vlan_filtering - return chip->info->max_vid ? 0 : -EOPNOTSUPP; - - mv88e6xxx_reg_lock(chip); -+ - err = mv88e6xxx_port_set_8021q_mode(chip, port, mode); -+ if (err) -+ goto unlock; -+ -+ err = mv88e6xxx_port_commit_pvid(chip, port); -+ if (err) -+ goto unlock; -+ -+unlock: - mv88e6xxx_reg_unlock(chip); - - return err; -@@ -1986,8 +2015,10 @@ static void mv88e6xxx_port_vlan_add(stru - struct mv88e6xxx_chip *chip = ds->priv; - bool untagged = vlan->flags & BRIDGE_VLAN_INFO_UNTAGGED; - bool pvid = vlan->flags & BRIDGE_VLAN_INFO_PVID; -+ struct mv88e6xxx_port *p = &chip->ports[port]; - bool warn; - u8 member; -+ int err; - u16 vid; - - if (!chip->info->max_vid) -@@ -2012,9 +2043,23 @@ static void mv88e6xxx_port_vlan_add(stru - dev_err(ds->dev, "p%d: failed to add VLAN %d%c\n", port, - vid, untagged ?

The first -time without buffer just to get the number of bytes required by the -modalias string (excluding the null byte), and a second time, after -buffer allocation, to fill the buffer. The allocation asks for an -additional byte, in order to store the trailing '\0'. However, the -buffer *length* provided to of_device_get_modalias() excludes this extra -byte. The internal use of snprintf() with a length that is exactly the -number of bytes to be written has the effect of using the last available -byte to store a '\0', which then smashes the last character of the -modalias string. - -Provide the actual size of the buffer to of_device_get_modalias() to fix -this issue. - -Note: the "str[size - 1] = '\0';" line is not really needed as snprintf -will anyway end the string with a null byte, but there is a possibility -that this function might be called on a struct device_node without -compatible, in this case snprintf() would not be executed.

The dscp mask must be 6 contiguous bits and -represents the area where the DSCP will be stored in the connmark. The -state mask is a minimum 1 bit length mask that must not overlap with the -dscpmask. It represents a flag which is set when the DSCP has been -stored in the conntrack mark.

relying on the software primarily for filling in egress routing -information. -When there is a hash collision between multiple flows, this allows the hardware -to maintain the entry for the most active flow. -Additionally, the hardware only keeps offloading active for entries with at -least 30 packets per second. - -With this rework, the code no longer creates a hardware entries directly. -Instead, the hardware entry is only created when the PPE reports a matching -unbound flow with the minimum target rate. -In order to reduce CPU overhead, looking for flows belonging to a hash entry -is rate limited to once every 100ms. - -This rework is also used as preparation for emulating bridge offload by -managing L4 offload entries on demand. - -Signed-off-by: Felix Fietkau <nbd@nbd.name>
