2022-02-25tracing: Uninline trace_trigger_soft_disabled() partlyChristophe Leroy
On a powerpc32 build with CONFIG_CC_OPTIMISE_FOR_SIZE, the inline keyword is not honored and trace_trigger_soft_disabled() appears approx 50 times in vmlinux. Adding -Winline to the build, the following message appears: ./include/linux/trace_events.h:712:1: error: inlining failed in call to 'trace_trigger_soft_disabled': call is unlikely and code size would grow [-Werror=inline] That function is rather big for an inlined function: c003df60 <trace_trigger_soft_disabled>: c003df60: 94 21 ff f0 stwu r1,-16(r1) c003df64: 7c 08 02 a6 mflr r0 c003df68: 90 01 00 14 stw r0,20(r1) c003df6c: bf c1 00 08 stmw r30,8(r1) c003df70: 83 e3 00 24 lwz r31,36(r3) c003df74: 73 e9 01 00 andi. r9,r31,256 c003df78: 41 82 00 10 beq c003df88 <trace_trigger_soft_disabled+0x28> c003df7c: 38 60 00 00 li r3,0 c003df80: 39 61 00 10 addi r11,r1,16 c003df84: 4b fd 60 ac b c0014030 <_rest32gpr_30_x> c003df88: 73 e9 00 80 andi. r9,r31,128 c003df8c: 7c 7e 1b 78 mr r30,r3 c003df90: 41 a2 00 14 beq c003dfa4 <trace_trigger_soft_disabled+0x44> c003df94: 38 c0 00 00 li r6,0 c003df98: 38 a0 00 00 li r5,0 c003df9c: 38 80 00 00 li r4,0 c003dfa0: 48 05 c5 f1 bl c009a590 <event_triggers_call> c003dfa4: 73 e9 00 40 andi. r9,r31,64 c003dfa8: 40 82 00 28 bne c003dfd0 <trace_trigger_soft_disabled+0x70> c003dfac: 73 ff 02 00 andi. r31,r31,512 c003dfb0: 41 82 ff cc beq c003df7c <trace_trigger_soft_disabled+0x1c> c003dfb4: 80 01 00 14 lwz r0,20(r1) c003dfb8: 83 e1 00 0c lwz r31,12(r1) c003dfbc: 7f c3 f3 78 mr r3,r30 c003dfc0: 83 c1 00 08 lwz r30,8(r1) c003dfc4: 7c 08 03 a6 mtlr r0 c003dfc8: 38 21 00 10 addi r1,r1,16 c003dfcc: 48 05 6f 6c b c0094f38 <trace_event_ignore_this_pid> c003dfd0: 38 60 00 01 li r3,1 c003dfd4: 4b ff ff ac b c003df80 <trace_trigger_soft_disabled+0x20> However it is located in a hot path so inlining it is important. But forcing inlining of the entire function by using __always_inline leads to increasing the text size by approx 20 kbytes. Instead, split the fonction in two parts, one part with the likely fast path, flagged __always_inline, and a second part out of line. With this change, on a powerpc32 with CONFIG_CC_OPTIMISE_FOR_SIZE vmlinux text increases by only 1,4 kbytes, which is partly compensated by a decrease of vmlinux data by 7 kbytes. On ppc64_defconfig which has CONFIG_CC_OPTIMISE_FOR_SPEED, this change reduces vmlinux text by more than 30 kbytes.

2022-02-25eprobes: Remove redundant event type informationSteven Rostedt (Google)
Currently, the event probes save the type of the event they are attached to when recording the event. For example: # echo 'e:switch sched/sched_switch prev_state=$prev_state prev_prio=$prev_prio next_pid=$next_pid next_prio=$next_prio' > dynamic_events # cat events/eprobes/switch/format name: switch ID: 1717 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:unsigned int __probe_type; offset:8; size:4; signed:0; field:u64 prev_state; offset:12; size:8; signed:0; field:u64 prev_prio; offset:20; size:8; signed:0; field:u64 next_pid; offset:28; size:8; signed:0; field:u64 next_prio; offset:36; size:8; signed:0; print fmt: "(%u) prev_state=0x%Lx prev_prio=0x%Lx next_pid=0x%Lx next_prio=0x%Lx", REC->__probe_type, REC->prev_state, REC->prev_prio, REC->next_pid, REC->next_prio The __probe_type adds 4 bytes to every event. One of the reasons for creating eprobes is to limit what is traced in an event to be able to limit what is written into the ring buffer. Having this redundant 4 bytes to every event takes away from this. The event that is recorded can be retrieved from the event probe itself, that is available when the trace is happening. For user space tools, it could simply read the dynamic_event file to find the event they are for. So there is really no reason to write this information into the ring buffer for every event.

2022-02-25tracing: Have traceon and traceoff trigger honor the instanceSteven Rostedt (Google)
If a trigger is set on an event to disable or enable tracing within an instance, then tracing should be disabled or enabled in the instance and not at the top level, which is confusing to users.

2022-02-25debugfs: Document that debugfs_create functions need not be error checkedDouglas Anderson
As talked about in commit b792e64021ec ("drm: no need to check return value of debugfs_create functions"), in many cases we can get away with totally skipping checking the errors of debugfs functions. Let's document that so people don't add new code that needlessly checks these errors. Probably this note could be added to a boatload of functions, but that's a lot of duplication. Let's just add it to the two most frequent ones and hope people will get the idea.

If the $fp is used for other purpose, the code generated this macro (as below) could trigger memory access fault. 0xffffffff8011510e <+80>: ld a1,-16(s0) 0xffffffff80115112 <+84>: ld s2,-8(a1) # <-- paging fault here The oops message during booting if compiled with 'irqoff' tracer enabled: [ 0.039615][ T0] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000f8 [ 0.041925][ T0] Oops [#1] [ 0.042063][ T0] Modules linked in: [ 0.042864][ T0] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.17.0-rc1-00233-g9a20c48d1ed2 #29 [ 0.043568][ T0] Hardware name: riscv-virtio,qemu (DT) [ 0.044343][ T0] epc : trace_hardirqs_on+0x56/0xe2 [ 0.044601][ T0] ra : restore_all+0x12/0x6e [ 0.044721][ T0] epc : ffffffff80126a5c ra : ffffffff80003b94 sp : ffffffff81403db0 [ 0.044801][ T0] gp : ffffffff8163acd8 tp : ffffffff81414880 t0 : 0000000000000020 [ 0.044882][ T0] t1 : 0098968000000000 t2 : 0000000000000000 s0 : ffffffff81403de0 [ 0.044967][ T0] s1 : 0000000000000000 a0 : 0000000000000001 a1 : 0000000000000100 [ 0.045046][ T0] a2 : 0000000000000000 a3 : 0000000000000000 a4 : 0000000000000000 [ 0.045124][ T0] a5 : 0000000000000000 a6 : 0000000000000000 a7 : 0000000054494d45 [ 0.045210][ T0] s2 : ffffffff80003b94 s3 : ffffffff81a8f1b0 s4 : ffffffff80e27b50 [ 0.045289][ T0] s5 : ffffffff81414880 s6 : ffffffff8160fa00 s7 : 00000000800120e8 [ 0.045389][ T0] s8 : 0000000080013100 s9 : 000000000000007f s10: 0000000000000000 [ 0.045474][ T0] s11: 0000000000000000 t3 : 7fffffffffffffff t4 : 0000000000000000 [ 0.045548][ T0] t5 : 0000000000000000 t6 : ffffffff814aa368 [ 0.045620][ T0] status: 0000000200000100 badaddr: 00000000000000f8 cause: 000000000000000d [ 0.046402][ T0] [<ffffffff80003b94>] restore_all+0x12/0x6e This because the $fp(aka. $s0) register is not used as frame pointer in the assembly entry code. resume_kernel: REG_L s0, TASK_TI_PREEMPT_COUNT(tp) bnez s0, restore_all REG_L s0, TASK_TI_FLAGS(tp) andi s0, s0, _TIF_NEED_RESCHED beqz s0, restore_all call preempt_schedule_irq j restore_all To fix above issue, here we add one extra level wrapper for function trace_hardirqs_{on,off}() so they can be safely called by low level entry code.

Obtaining a MAC address may be deferred in cases when the MAC is stored in an NVMEM block, for example, and it may not be ready upon the first retrieval attempt and return EPROBE_DEFER. It is also possible that a port that does not rely on NVMEM has been already created when getting the defer request. Thus, also the resources allocated previously must be freed when doing a roll-back.

2022-02-24KVM: x86/mmu: make apf token non-zero to fix bugLiang Zhang
In current async pagefault logic, when a page is ready, KVM relies on kvm_arch_can_dequeue_async_page_present() to determine whether to deliver a READY event to the Guest. This function test token value of struct kvm_vcpu_pv_apf_data, which must be reset to zero by Guest kernel when a READY event is finished by Guest. If value is zero meaning that a READY event is done, so the KVM can deliver another. But the kvm_arch_setup_async_pf() may produce a valid token with zero value, which is confused with previous mention and may lead the loss of this READY event. This bug may cause task blocked forever in Guest: INFO: task stress:7532 blocked for more than 1254 seconds.

2022-02-24openvswitch: Fix setting ipv6 fields causing hw csum failurePaul Blakey
Ipv6 ttl, label and tos fields are modified without first pulling/pushing the ipv6 header, which would have updated the hw csum (if available). This might cause csum validation when sending the packet to the stack, as can be seen in the trace below. Fix this by updating skb->csum if available. Trace resulted by ipv6 ttl dec and then sending packet to conntrack [actions: set(ipv6(hlimit=63)),ct(zone=99)]: [295241.900063] s_pf0vf2: hw csum failure [295241.923191] Call Trace: [295241.925728] <IRQ> [295241.927836] dump_stack+0x5c/0x80 [295241.931240] __skb_checksum_complete+0xac/0xc0 [295241.935778] nf_conntrack_tcp_packet+0x398/0xba0 [nf_conntrack] [295241.953030] nf_conntrack_in+0x498/0x5e0 [nf_conntrack] [295241.958344] __ovs_ct_lookup+0xac/0x860 [openvswitch] [295241.968532] ovs_ct_execute+0x4a7/0x7c0 [openvswitch] [295241.979167] do_execute_actions+0x54a/0xaa0 [openvswitch] [295242.001482] ovs_execute_actions+0x48/0x100 [openvswitch] [295242.006966] ovs_dp_process_packet+0x96/0x1d0 [openvswitch] [295242.012626] ovs_vport_receive+0x6c/0xc0 [openvswitch] [295242.028763] netdev_frame_hook+0xc0/0x180 [openvswitch] [295242.034074] __netif_receive_skb_core+0x2ca/0xcb0 [295242.047498] netif_receive_skb_internal+0x3e/0xc0 [295242.052291] napi_gro_receive+0xba/0xe0 [295242.056231] mlx5e_handle_rx_cqe_mpwrq_rep+0x12b/0x250 [mlx5_core] [295242.062513] mlx5e_poll_rx_cq+0xa0f/0xa30 [mlx5_core] [295242.067669] mlx5e_napi_poll+0xe1/0x6b0 [mlx5_core] [295242.077958] net_rx_action+0x149/0x3b0 [295242.086762] __do_softirq+0xd7/0x2d6 [295242.090427] irq_exit+0xf7/0x100 [295242.093748] do_IRQ+0x7f/0xd0 [295242.096806] common_interrupt+0xf/0xf [295242.100559] </IRQ> [295242.102750] RIP: 0033:0x7f9022e88cbd [295242.125246] RSP: 002b:00007f9022282b20 EFLAGS: 00000246 ORIG_RAX: ffffffffffffffda [295242.132900] RAX: 0000000000000005 RBX: 0000000000000010 RCX: 0000000000000000 [295242.140120] RDX: 00007f9022282ba8 RSI: 00007f9022282a30 RDI: 00007f9014005c30 [295242.147337] RBP: 00007f9014014d60 R08: 0000000000000020 R09: 00007f90254a8340 [295242.154557] R10: 00007f9022282a28 R11: 0000000000000246 R12: 0000000000000000 [295242.161775] R13: 00007f902308c000 R14: 000000000000002b R15: 00007f9022b71f40 Fixes: 3fdbd1ce11e5 ("openvswitch: add ipv6 'set' action") Signed-off-by: Paul Blakey <paulb@nvidia.com> Link: https://lore.kernel.org/r/20220223163416.24096-1-paulb@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
