2023-01-16wifi: mt76: dma: fix a regression in adding rx buffersFelix Fietkau
When adding WED support, mt76_dma_add_buf was accidentally changed to set the skip_buf0 flag for tx buffers on the wrong queue descriptor entry. Additionally, there is a rxwi leak when rx buffer allocation fails. Fix this and make the code more readable by adding a separate function for adding rx buffers.

2023-01-16Merge branch 'net-microchip-vcap-rules'David S. Miller
Steen Hegelund says: ==================== net: microchip: Add support for two classes of VCAP rules This adds support for two classes of VCAP rules: - Permanent rules (added e.g. for PTP support) - TC user rules (added by the TC userspace tool) For this to work the VCAP Loopups must be enabled from boot, so that the "internal" clients like PTP can add rules that are always active. When the TC tool add a flower filter the VCAP rule corresponding to this filter will be disabled (kept in memory) until a TC matchall filter creates a link from chain 0 to the chain (lookup) where the flower filter was added. When the flower filter is enabled it will be written to the appropriate VCAP lookup and become active in HW. Likewise the flower filter will be disabled if there is no link from chain 0 to the chain of the filter (lookup), and when that happens the corresponding VCAP rule will be read from the VCAP instance and stored in memory until it is deleted or enabled again. Version History: ================ v4 Removed a leftover 'Fixes' tag from v2. No functional changes. v3 Removed the change that allowed rules to always be added in the LAN996x even though the lookups are not enabled (Horatiu Vultur). This was sent separately to net instead. Removed the 'Fixes' tags due to the patch sent to net by Horatiu Vultur. Added a check for validity of the chain source when enabling a lookup. v2 Adding a missing goto exit in vcap_add_rule (Dan Carpenter). Added missing checks for error returns in vcap_enable_rule. v1 Initial version ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This changes the way the chain information verified when adding a new tc flower filter. When adding a flower filter it is now checked that the filter contains a goto action to one of the IS2 VCAP lookups, except for the last lookup which may omit this goto action. It is also checked if you attempt to add multiple matchall filters to enable the same VCAP lookup. This will be rejected.

2023-01-16net: microchip: vcap api: Use src and dst chain id to chain VCAP lookupsSteen Hegelund
This adds both the source and destination chain id to the information kept for enabled port lookups. This allows enabling and disabling a chain of lookups by walking the chain information for a port. This changes the way that VCAP lookups are enabled from userspace: instead of one matchall rule that enables all the 4 Sparx5 IS2 lookups, you need a matchall rule per lookup. In practice that is done by adding one matchall rule in chain 0 to goto IS2 Lookup 0, and then for each lookup you add a rule per lookup (low priority) that does a goto to the next lookup chain. Examples: If you want IS2 Lookup 0 to be enabled you add the same matchall filter as before: tc filter add dev eth12 ingress chain 0 prio 1000 handle 1000 matchall \ skip_sw action goto chain 8000000 If you also want to enable lookup 1 to 3 in IS2 and chain them you need to add the following matchall filters: tc filter add dev eth12 ingress chain 8000000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8100000 tc filter add dev eth12 ingress chain 8100000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8200000 tc filter add dev eth12 ingress chain 8200000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8300000 Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S.

2023-01-16l2tp: close all race conditions in l2tp_tunnel_register()Cong Wang
The code in l2tp_tunnel_register() is racy in several ways: 1. It modifies the tunnel socket _after_ publishing it. 2. It calls setup_udp_tunnel_sock() on an existing socket without locking. 3. It changes sock lock class on fly, which triggers many syzbot reports. This patch amends all of them by moving socket initialization code before publishing and under sock lock. As suggested by Jakub, the l2tp lockdep class is not necessary as we can just switch to bh_lock_sock_nested().

More importantly, with IDR we can hold the ID before a successful registration so that we don't need to worry about late error handling, it is not easy to rollback socket changes.

2023-01-16net: dsa: mv88e6xxx: Enable PTP receive for mv88e6390Kurt Kanzenbach
The switch receives management traffic such as STP and LLDP. However, PTP messages are not received, only transmitted. Ideally, the switch would trap all PTP messages to the management CPU. This particular switch has a PTP block which identifies PTP messages and traps them to a dedicated port. There is a register to program this destination. This is not used at the moment. Therefore, program it to the same port as the MGMT traffic is trapped to. This allows to receive PTP messages as soon as timestamping is enabled. In addition, the datasheet mentions that this register is not valid e.g., for 6190 variants. So, add a new PTP operation which is added for the 6390 and 6290 devices.

2023-01-16net/sched: sch_taprio: fix possible use-after-freeEric Dumazet
syzbot reported a nasty crash [1] in net_tx_action() which made little sense until we got a repro. This repro installs a taprio qdisc, but providing an invalid TCA_RATE attribute. qdisc_create() has to destroy the just initialized taprio qdisc, and taprio_destroy() is called. However, the hrtimer used by taprio had already fired, therefore advance_sched() called __netif_schedule(). Then net_tx_action was trying to use a destroyed qdisc. We can not undo the __netif_schedule(), so we must wait until one cpu serviced the qdisc before we can proceed. Many thanks to Alexander Potapenko for his help.

2023-01-16net: stmmac: Fix queue statistics readingKurt Kanzenbach
Correct queue statistics reading. All queue statistics are stored as unsigned long values. The retrieval for ethtool fetches these values as u64. However, on some systems the size of the counters are 32 bit. That yields wrong queue statistic counters e.g., on arm32 systems such as the stm32mp157. Fix it by using the correct data type. Tested on Olimex STMP157-OLinuXino-LIME2 by simple running linuxptp for a short period of time: Non-patched kernel: |root@st1:~# ethtool -S eth0 | grep q0 | q0_tx_pkt_n: 3775276254951 # ??? | q0_tx_irq_n: 879 | q0_rx_pkt_n: 1194000908909 # ??? | q0_rx_irq_n: 278 Patched kernel: |root@st1:~# ethtool -S eth0 | grep q0 | q0_tx_pkt_n: 2434 | q0_tx_irq_n: 1274 | q0_rx_pkt_n: 1604 | q0_rx_irq_n: 846 Fixes: 68e9c5dee1cf ("net: stmmac: add ethtool per-queue statistic framework") Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Cc: Vijayakannan Ayyathurai <vijayakannan.ayyathurai@intel.com> Cc: Wong Vee Khee <vee.khee.wong@linux.intel.com> Signed-off-by: David S.
