2023-07-07x86/smp: Don't send INIT to boot CPUThomas Gleixner1-0/+8
Parking CPUs in INIT works well, except for the crash case when the CPU which invokes smp_park_other_cpus_in_init() is not the boot CPU. Sending INIT to the boot CPU resets the whole machine. Prevent this by validating that this runs on the boot CPU. If not fall back and let CPUs hang in HLT.

2023-07-06Merge branch 'fix-dropping-of-oversize-preemptible-frames-with-felix-dsa-driver'Jakub Kicinski6-37/+56
Vladimir Oltean says: ==================== Fix dropping of oversize preemptible frames with felix DSA driver It has been reported that preemptible traffic doesn't completely behave as expected. Namely, large packets should be able to be squeezed (through fragmentation) through taprio time slots smaller than the transmission time of the full frame. That does not happen due to logic in the driver (for oversize frame dropping with taprio) that was not updated in order for this use case to work. I am not sure whether it qualifies as "net" material, because some structural changes are involved, and it is a "never worked" scenario. OTOH, this is a complaint coming from users for a v6.4 kernel. It's up to maintainers to decide whether this series can be considered; I've submitted it as non-RFC in the optimistic case that it will be :) Demo script illustrating the issue below. add_taprio() { local ifname=$1 echo "Creating root taprio" tc qdisc replace dev $ifname handle 8001: parent root stab overhead 24 taprio \ num_tc 8 \ map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \ base-time 0 \ sched-entry S 01 1216 \ sched-entry S fe 12368 \ fp P E E E E E E E \ flags 0x2 } remove_taprio() { local ifname=$1 echo "Removing taprio" tc qdisc del dev $ifname root } ip netns add ns0 ip link set eno0 netns ns0 && ip -n ns0 link set eno0 up && ip -n ns0 addr add 192.168.100.1/24 dev eno0 ip addr add 192.168.100.2/24 dev swp0 && ip link set swp0 up ip netns exec ns0 ethtool --set-mm eno0 pmac-enabled on verify-enabled off tx-enabled on ethtool --set-mm swp0 pmac-enabled on verify-enabled off tx-enabled on add_taprio swp0 ping 192.168.100.1 -s 1000 -c 5 # sent through TC0 ethtool -I --show-mm swp0 | grep MACMergeFragCountTx # should increase ip addr flush swp0 && ip link set swp0 down remove_taprio swp0 ethtool --set-mm swp0 pmac-enabled off verify-enabled off tx-enabled off ip netns exec ns0 ethtool --set-mm eno0 pmac-enabled off verify-enabled off tx-enabled off ip netns del ns0 ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2023-07-06net: mscc: ocelot: fix oversize frame dropping for preemptible TCsVladimir Oltean2-6/+22
This switch implements Hold/Release in a strange way, with no control from the user as required by IEEE 802.1Q-2018 through Set-And-Hold-MAC and Set-And-Release-MAC, but rather, it emits HOLD requests implicitly based on the schedule. Namely, when the gate of a preemptible TC is about to close (actually QSYS::PREEMPTION_CFG.HOLD_ADVANCE octet times in advance of this event), the QSYS seems to emit a HOLD request pulse towards the MAC which preempts the currently transmitted packet, and further packets are held back in the queue system. This allows large frames to be squeezed through small time slots, because HOLD requests initiated by the gate events result in the frame being segmented in multiple fragments, the bit time of which is equal to the size of the time slot. It has been reported that the vsc9959_tas_guard_bands_update() logic breaks this, because it doesn't take preemptible TCs into account, and enables oversized frame dropping when the time slot doesn't allow a full MTU to be sent, but it does allow 2*minFragSize to be sent (128B). Packets larger than 128B are dropped instead of being sent in multiple fragments. Confusingly, the manual says: | For guard band, SDU calculation of a traffic class of a port, if | preemption is enabled (through 'QSYS::PREEMPTION_CFG.P_QUEUES') then | QSYS::PREEMPTION_CFG.HOLD_ADVANCE is used, otherwise | QSYS::QMAXSDU_CFG_*.QMAXSDU_* is used. but this only refers to the static guard band durations, and the QMAXSDU_CFG_* registers have dual purpose - the other being oversized frame dropping, which takes place irrespective of whether frames are preemptible or express. So, to fix the problem, we need to call vsc9959_tas_guard_bands_update() from ocelot_port_update_active_preemptible_tcs(), and modify the guard band logic to consider a different (lower) oversize limit for preemptible traffic classes.

2023-07-06net: dsa: felix: make vsc9959_tas_guard_bands_update() visible to ocelot->opsVladimir Oltean4-5/+4
In a future change we will need to make ocelot_port_update_active_preemptible_tcs() call vsc9959_tas_guard_bands_update(), but that is currently not possible, since the ocelot switch lib does not have access to functions private to the DSA wrapper. Move the pointer to vsc9959_tas_guard_bands_update() from felix->info (which is private to the DSA driver) to ocelot->ops (which is also visible to the ocelot switch lib).

2023-07-06net: mscc: ocelot: extend ocelot->fwd_domain_lock to cover ocelot->tas_lockVladimir Oltean5-26/+30
In a future commit we will have to call vsc9959_tas_guard_bands_update() from ocelot_port_update_active_preemptible_tcs(), and that will be impossible due to the AB/BA locking dependencies between ocelot->tas_lock and ocelot->fwd_domain_lock. Just like we did in commit 3ff468ef987e ("net: mscc: ocelot: remove struct ocelot_mm_state :: lock"), the only solution is to expand the scope of ocelot->fwd_domain_lock for it to also serialize changes made to the Time-Aware Shaper, because those will have to result in a recalculation of cut-through TCs, which is something that depends on the forwarding domain.

Use tracing_lseek() that tests for this instead of calling the default seq lseek handler. - Check for negative instead of -E2BIG for error on strscpy() returns Instead of testing for -E2BIG from strscpy(), to be more robust, check for less than zero, which will make sure it catches any error that strscpy() may someday return. * tag 'trace-v6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/boot: Test strscpy() against less than zero for error arm64: ftrace: fix build error with CONFIG_FUNCTION_GRAPH_TRACER=n tracing: Fix null pointer dereference in tracing_err_log_open()

2023-07-06i2c: xiic: Don't try to handle more interrupt events after errorRobert Hancock1-0/+2
In xiic_process, it is possible that error events such as arbitration lost or TX error can be raised in conjunction with other interrupt flags such as TX FIFO empty or bus not busy. Error events result in the controller being reset and the error returned to the calling request, but the function could potentially try to keep handling the other events, such as by writing more messages into the TX FIFO. Since the transaction has already failed, this is not helpful and will just cause issues. This problem has been present ever since: commit 7f9906bd7f72 ("i2c: xiic: Service all interrupts in isr") which allowed non-error events to be handled after errors, but became more obvious after: commit 743e227a8959 ("i2c: xiic: Defer xiic_wakeup() and __xiic_start_xfer() in xiic_process()") which reworked the code to add a WARN_ON which triggers if both the xfer_more and wakeup_req flags were set, since this combination is not supposed to happen, but was occurring in this scenario. Skip further interrupt handling after error flags are detected to avoid this problem.
