Ioana Ciornei says: ==================== dpaa2-eth: misc fixes This patch set adds a couple of fixes around updating configuration on MAC change. Depending on when MC connects the DPNI to a MAC, both the MAC address and TX FQIDs should be updated everytime there is a change in configuration. Changes in v2: - used reverse christmas tree ordering in patch 2/2 Changes in v3: - add a missing new line - go back to FQ based enqueueing after a transient error ==================== Signed-off-by: -

Depending on when MC connects the DPNI to a MAC, Tx FQIDs may not be available during probe time. Read the FQIDs each time the link goes up to avoid using invalid values. In case an error occurs or an invalid value is retrieved, fall back to QDID-based enqueueing. Fixes: 1fa0f68c ("dpaa2-eth: Use FQ-based DPIO enqueue API") Signed-off-by:

Some drivers just call phy_ethtool_ksettings_set() to set the links, for those phy drivers that use genphy_read_status(), if autoneg is on, and the link is up, than execute "ethtool -s ethx autoneg on" will cause "link partner" information disappear. The call trace is phy_ethtool_ksettings_set()->phy_start_aneg() ->linkmode_zero(phydev->lp_advertising)->genphy_read_status(), the link didn't change, so genphy_read_status() just return, and phydev->lp_advertising is zero now. This patch moves the clear operation of lp_advertising from phy_start_aneg() to genphy_read_lpa()/genphy_c45_read_lpa(), and if autoneg on and autoneg not complete, just clear what the generic functions care about.

Commit 7f683b92 ("i825xx: switch to switch to dma_alloc_attrs") switched dma allocation over to dma_alloc_attr, but didn't convert the SNI part to request consistent DMA memory. This broke sni_82596 since driver doesn't do dma_cache_sync for performance reasons. Fix this by using different DMA_ATTRs for lasi_82596 and sni_82596.

Later when binding another port by sctp_setsockopt_bindx(), a new bucket will be created as bp->port is not set. sctp's autobind is supposed to call sctp_autobind() where it does all things including setting bp->port. Since sctp_autobind() is called in sctp_sendmsg() if the sk is not yet bound, it should have skipped the auto bind. THis patch is to avoid calling inet_autobind() in inet_send_prepare() by changing sctp_prot .no_autobind with true, also remove the unused .get_port.

When a application sends many packets with the same txtime, they may be transmitted out of order (different from the order in which they were enqueued). This happens because when inserting elements into the tree, when the txtime of two packets are the same, the new packet is inserted at the left side of the tree, causing the reordering. The only effect of this change should be that packets with the same txtime will be transmitted in the order they are enqueued. The application in question (the AVTP GStreamer plugin, still in development) is sending video traffic, in which each video frame have a single presentation time, the problem is that when packetizing, multiple packets end up with the same txtime. The receiving side was rejecting packets because they were being received out of order. Fixes: 25db26a9 ("net/sched: Introduce the ETF Qdisc") Reported-by:

tc_ctl_action() has the ability to loop forever if tcf_action_add() returns -EAGAIN. This special case has been done in case a module needed to be loaded, but it turns out that tcf_add_notify() could also return -EAGAIN if the socket sk_rcvbuf limit is hit. We need to separate the two cases, and only loop for the module loading case. While we are at it, add a limit of 10 attempts since unbounded loops are always scary. syzbot repro was something like : socket(PF_NETLINK, SOCK_RAW|SOCK_NONBLOCK, NETLINK_ROUTE) = 3 write(3, ..., 38) = 38 setsockopt(3, SOL_SOCKET, SO_RCVBUF, [0], 4) = 0 sendmsg(3, {msg_name(0)=NULL, msg_iov(1)=[{..., 388}], msg_controllen=0, msg_flags=0x10}, ...)

the following script: # tc qdisc add dev eth0 clsact # tc filter add dev eth0 egress protocol ip matchall \ > action mpls push protocol mpls_uc label 0x355aa bos 1 causes corruption of all IP packets transmitted by eth0. On TC egress, we can't rely on the value of skb->mac_len, because it's 0 and a MPLS 'push' operation will result in an overwrite of the first 4 octets in the packet L2 header (e.g. the Destination Address if eth0 is an Ethernet); the same error pattern is present also in the MPLS 'pop' operation. Fix this error in act_mpls data plane, computing 'mac_len' as the difference between the network header and the mac header (when not at TC ingress), and use it in MPLS 'push'/'pop' core functions. v2: unbreak 'make htmldocs' because of missing documentation of 'mac_len' in skb_mpls_pop(), reported by kbuild test robot CC: Lorenzo Bianconi <lorenzo@kernel.org> Fixes: 2a2ea508 ("net: sched: add mpls manipulation actions to TC") Reviewed-by:Simon Horman <simon.horman@netronome.com> Acked-by:

the following script: # tc qdisc add dev eth0 clsact # tc filter add dev eth0 egress matchall action mpls pop implicitly makes the kernel drop all packets transmitted by eth0, if they don't have a MPLS header. This behavior is uncommon: other encapsulations (like VLAN) just let the packet pass unmodified. Since the result of MPLS 'pop' operation would be the same regardless of the presence / absence of MPLS header(s) in the original packet, we can let skb_mpls_pop() return 0 when dealing with non-MPLS packets. For the OVS use-case, this is acceptable because __ovs_nla_copy_actions() already ensures that MPLS 'pop' operation only occurs with packets having an MPLS Ethernet type (and there are no other callers in current code, so the semantic change should be ok). v2: better documentation of use-cases for skb_mpls_pop(), thanks to Simon Horman Fixes: 2a2ea508 ("net: sched: add mpls manipulation actions to TC") Reviewed-by:

While invalidating the dst, we assign backhole_netdev instead of loopback device. However, this device does not have idev pointer and hence no ip6_ptr even if IPv6 is enabled. Possibly this has triggered the syzbot reported crash. The syzbot report does not have reproducer, however, this is the only device that doesn't have matching idev created. Crash instruction is : static inline bool ip6_ignore_linkdown(const struct net_device *dev) { const struct inet6_dev *idev = __in6_dev_get(dev); return !!idev->cnf.ignore_routes_with_linkdown; <= crash } Also ipv6 always assumes presence of idev and never checks for it being NULL (as does the above referenced code). So adding a idev for the blackhole_netdev to avoid this class of crashes in the future. Signed-off-by: -

We now do separate logic and consider both ALLMULTI and MULTICAST flags on the device. Fixes: 11ba961c ("net: aquantia: Fix IFF_ALLMULTI flag functionality") Signed-off-by:

Individual descriptors on LRO TCP session should be checked for CRC errors. It was discovered that HW recalculates L4 checksums on LRO session and does not break it up on bad L4 csum. Thus, driver should aggregate HW LRO L4 statuses from all individual buffers of LRO session and drop packet if one of the buffers has bad L4 checksum. Fixes: f38f1ee8 ("net: aquantia: check rx csum for all packets in LRO session") Signed-off-by:

>From HW specification to correctly reset HW caches (this is a required workaround when stopping the device), register bit should actually be toggled. It was previosly always just set. Due to the way driver stops HW this never actually caused any issues, but it still may, so cleaning this up.

Chip temperature is a two byte word, colocated internally with cable length data. We do all readouts from HW memory by dwords, thus we should clear extra high bytes, otherwise temperature output gets weird as soon as we attach a cable to the NIC.

(kvalo: cherry picked from commit 1340cc63 in wireless-drivers-next to wireless-drivers as this a frequently reported regression) Bad latency is found on QCA988x, the issue was introduced by commit 4504f0e5 ("ath10k: sdio: workaround firmware UART pin configuration bug"). If uart_pin_workaround is false, this change will set uart pin even if uart_print is false. Tested HW: QCA9880 Tested FW: 10.2.4-1.0-00037 Fixes: 4504f0e5 ("ath10k: sdio: workaround firmware UART pin configuration bug") Signed-off-by:

In nsim_fib_init(), if register_fib_notifier failed, nsim_fib_net_ops should be unregistered before return. In nsim_fib_exit(), unregister_fib_notifier should be called before nsim_fib_net_ops be unregistered, otherwise may cause use-after-free: BUG: KASAN: use-after-free in nsim_fib_event_nb+0x342/0x570 [netdevsim] Read of size 8 at addr ffff8881daaf4388 by task kworker/0:3/3499 CPU: 0 PID: 3499 Comm: kworker/0:3 Not tainted 5.3.0-rc7+ #30 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1ubuntu1 04/01/2014 Workqueue: ipv6_addrconf addrconf_dad_work [ipv6] Call Trace: __dump_stack lib/dump_stack.c:77 [inline] dump_stack+0xa9/0x10e lib/dump_stack.c:113 print_address_description+0x65/0x380 mm/kasan/report.c:351 __kasan_report+0x149/0x18d mm/kasan/report.c:482 kasan_report+0xe/0x20 mm/kasan/common.c:618 nsim_fib_event_nb+0x342/0x570 [netdevsim] notifier_call_chain+0x52/0xf0 kernel/notifier.c:95 __atomic_notifier_call_chain+0x78/0x140 kernel/notifier.c:185 call_fib_notifiers+0x30/0x60 net/core/fib_notifier.c:30 call_fib6_entry_notifiers+0xc1/0x100 [ipv6] fib6_add+0x92e/0x1b10 [ipv6] __ip6_ins_rt+0x40/0x60 [ipv6] ip6_ins_rt+0x84/0xb0 [ipv6] __ipv6_ifa_notify+0x4b6/0x550 [ipv6] ipv6_ifa_notify+0xa5/0x180 [ipv6] addrconf_dad_completed+0xca/0x640 [ipv6] addrconf_dad_work+0x296/0x960 [ipv6] process_one_work+0x5c0/0xc00 kernel/workqueue.c:2269 worker_thread+0x5c/0x670 kernel/workqueue.c:2415 kthread+0x1d7/0x200 kernel/kthread.c:255 ret_from_fork+0x3a/0x50 arch/x86/entry/entry_64.S:352 Allocated by task 3388: save_stack+0x19/0x80 mm/kasan/common.c:69 set_track mm/kasan/common.c:77 [inline] __kasan_kmalloc.constprop.3+0xa0/0xd0 mm/kasan/common.c:493 kmalloc include/linux/slab.h:557 [inline] kzalloc include/linux/slab.h:748 [inline] ops_init+0xa9/0x220 net/core/net_namespace.c:127 __register_pernet_operations net/core/net_namespace.c:1135 [inline] register_pernet_operations+0x1d4/0x420 net/core/net_namespace.c:1212 register_pernet_subsys+0x24/0x40 net/core/net_namespace.c:1253 nsim_fib_init+0x12/0x70 [netdevsim] veth_get_link_ksettings+0x2b/0x50 [veth] do_one_initcall+0xd4/0x454 init/main.c:939 do_init_module+0xe0/0x330 kernel/module.c:3490 load_module+0x3c2f/0x4620 kernel/module.c:3841 __do_sys_finit_module+0x163/0x190 kernel/module.c:3931 do_syscall_64+0x72/0x2e0 arch/x86/entry/common.c:296 entry_SYSCALL_64_after_hwframe+0x49/0xbe Freed by task 3534: save_stack+0x19/0x80 mm/kasan/common.c:69 set_track mm/kasan/common.c:77 [inline] __kasan_slab_free+0x130/0x180 mm/kasan/common.c:455 slab_free_hook mm/slub.c:1423 [inline] slab_free_freelist_hook mm/slub.c:1474 [inline] slab_free mm/slub.c:3016 [inline] kfree+0xe9/0x2d0 mm/slub.c:3957 ops_free net/core/net_namespace.c:151 [inline] ops_free_list.part.7+0x156/0x220 net/core/net_namespace.c:184 ops_free_list net/core/net_namespace.c:182 [inline] __unregister_pernet_operations net/core/net_namespace.c:1165 [inline] unregister_pernet_operations+0x221/0x2a0 net/core/net_namespace.c:1224 unregister_pernet_subsys+0x1d/0x30 net/core/net_namespace.c:1271 nsim_fib_exit+0x11/0x20 [netdevsim] nsim_module_exit+0x16/0x21 [netdevsim] __do_sys_delete_module kernel/module.c:1015 [inline] __se_sys_delete_module kernel/module.c:958 [inline] __x64_sys_delete_module+0x244/0x330 kernel/module.c:958 do_syscall_64+0x72/0x2e0 arch/x86/entry/common.c:296 entry_SYSCALL_64_after_hwframe+0x49/0xbe Reported-by:
