Before this patch, gfs2_make_fs_rw +called init_threads to initialize the quotad and logd threads.

Some reasons: + +- ICMP6 neighbor solicitation messages are unregistered multicast + packets as far as the bridge is concerned. So if we stop flooding + multicast, the outside world cannot ping the bridge device's IPv6 + link-local address. + +- There might be foreign interfaces bridged with our DSA switch ports + (sending a packet towards the host does not necessarily equal + termination, but maybe software forwarding). So if there is no one + interested in that multicast traffic in the local network stack, that + doesn't mean nobody is. + +- PTP over L4 (IPv4, IPv6) is multicast, but is unregistered as far as + the bridge is concerned. This should reach the CPU port. + +- The switch driver might not do FDB partitioning. And since we don't + even bother to do more fine-grained flood disabling (such as "disable + flooding _from_port_N_ towards the CPU port" as opposed to "disable + flooding _from_any_port_ towards the CPU port"), this breaks standalone + ports, or even multiple bridges where one has an IGMP querier and one + doesn't. + +Reverting the logic makes all of the above work. + +Fixes: a8b659e7ff75 ("net: dsa: act as passthrough for bridge port flags") +Fixes: 08cc83cc7fd8 ("net: dsa: add support for BRIDGE_MROUTER attribute") +Signed-off-by: Vladimir Oltean +Signed-off-by: David S.

The energy calculation in EAS does arithmetic operation based on +the EM em_cpu_energy(). Current implementation of that function uses +em_perf_state::cost as a pre-computed cost coefficient equal to: +cost = power * max_frequency / frequency. +The 'power' is expressed in milli-Watts (or in abstract scale). + +There are corner cases when the EAS energy calculation for two Performance +Domains (PDs) return the same value. The EAS compares these values to +choose smaller one. It might happen that this values are equal due to +rounding error. In such scenario, we need better resolution, e.g. 1000 +times better. To provide this possibility increase the resolution in the +em_perf_state::cost for 64-bit architectures. The cost of increasing +resolution on 32-bit is pretty high (64-bit division) and is not justified +since there are no new 32bit big.LITTLE EAS systems expected which would +benefit from this higher resolution. + +This patch allows to avoid the rounding to milli-Watt errors, which might +occur in EAS energy estimation for each PD. The rounding error is common +for small tasks which have small utilization value. + +There are two places in the code where it makes a difference: +1. In the find_energy_efficient_cpu() where we are searching for +best_delta. We might suffer there when two PDs return the same result, +like in the example below. + +Scenario: +Low utilized system e.g. ~200 sum_util for PD0 and ~220 for PD1. There +are quite a few small tasks ~10-15 util. These tasks would suffer for +the rounding error. These utilization values are typical when running games +on Android.

However, qdisc creation may fail, and in that +case noop_qdisc is used instead. Its dev_queue doesn't point to the +right queue, so sch_htb can lose track of used netdev queues, which will +cause internal inconsistencies. + +This commit fixes this bug by keeping track of the netdev queue inside +struct htb_class. All reads of cl->leaf.q->dev_queue are replaced by the +new field, the two values are synced on writes, and WARNs are added to +assert equality of the two values. + +The driver API has changed: when TC_HTB_LEAF_DEL needs to move a queue, +the driver used to pass the old and new queue IDs to sch_htb. Now that +there is a new field (offload_queue) in struct htb_class that needs to +be updated on this operation, the driver will pass the old class ID to +sch_htb instead (it already knows the new class ID). + +Fixes: d03b195b5aa0 ("sch_htb: Hierarchical QoS hardware offload") +Signed-off-by: Maxim Mikityanskiy +Reviewed-by: Tariq Toukan +Link: https://lore.kernel.org/r/20210826115425.1744053-1-maximmi@nvidia.com +Signed-off-by: Jakub Kicinski +Signed-off-by: Sasha Levin +--- + .../net/ethernet/mellanox/mlx5/core/en/qos.c | 15 ++- + .../net/ethernet/mellanox/mlx5/core/en/qos.h | 4 +- + .../net/ethernet/mellanox/mlx5/core/en_main.c | 3 +- + include/net/pkt_cls.h | 3 +- + net/sched/sch_htb.c | 97 ++++++++++++------- + 5 files changed, 72 insertions(+), 50 deletions(-) + +diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en/qos.c b/drivers/net/ethernet/mellanox/mlx5/core/en/qos.c +index 5efe3278b0f6..1fd8baf19829 100644 +--- a/drivers/net/ethernet/mellanox/mlx5/core/en/qos.c ++++ b/drivers/net/ethernet/mellanox/mlx5/core/en/qos.c +@@ -733,8 +733,8 @@ static void mlx5e_reset_qdisc(struct net_device *dev, u16 qid) + spin_unlock_bh(qdisc_lock(qdisc));

driver detects interrupt edges by tracking the last state +it has seen (and has triggered the interrupt handler for). This works +fine, but only if the interrupt does not change state while masked. + +For example, if an interrupt is unmasked while the state is HIGH, +the stored last_value for that interrupt might still be LOW. Then, +when the remote processor triggers smsm_intr() we assume that nothing +has changed, even though the state might have changed from HIGH to LOW. + +Attempt to fix this by checking the current remote state before +unmasking an IRQ. Use atomic operations to avoid the interrupt handler +from interfering with the unmask function. + +This fixes modem crashes in some edge cases with the BAM-DMUX driver. +Specifically, the BAM-DMUX interrupt handler is not called for the +HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded +(and therefore unmasks the interrupt) after the modem was already started: + +qcom-q6v5-mss 4080000.remoteproc: fatal error received: a2_task.c:3188: + Assert FALSE failed: A2 DL PER deadlock timer expired waiting for Apps ACK + +Fixes: c97c4090ff72 ("soc: qcom: smsm: Add driver for Qualcomm SMSM") +Signed-off-by: Stephan Gerhold +Link: https://lore.kernel.org/r/20210712135703.324748-2-stephan@gerhold.net +Signed-off-by: Bjorn Andersson +Signed-off-by: Sasha Levin +--- + drivers/soc/qcom/smsm.c | 11 ++++++++--- + 1 file changed, 8 insertions(+), 3 deletions(-) + +diff --git a/drivers/soc/qcom/smsm.c b/drivers/soc/qcom/smsm.c +index 1d3d5e3ec2b0..6e9a9cd28b17 100644 +--- a/drivers/soc/qcom/smsm.c ++++ b/drivers/soc/qcom/smsm.c +@@ -109,7 +109,7 @@ struct smsm_entry { + DECLARE_BITMAP(irq_enabled, 32);

But parsing console logs is error prone. Users of +/dev/mcelog should expect to find any early errors logged to standard +places. + +Add a new flag MCP_QUEUE_LOG to machine_check_poll() to be used in early +machine check initialization to indicate that any errors found should +just be queued to genpool. When mcheck_late_init() is called it will +call mce_schedule_work() to actually log and flush any errors queued in +the genpool. + + [ Based on an original patch, commit message by and completely + productized by Tony Luck. ] + +Fixes: 5de97c9f6d85 ("x86/mce: Factor out and deprecate the /dev/mcelog driver") +Reported-by: Sumanth Kamatala +Signed-off-by: Borislav Petkov +Signed-off-by: Tony Luck +Signed-off-by: Borislav Petkov +Link: https://lkml.kernel.org/r/20210824003129.GA1642753@agluck-desk2.amr.corp.intel.com +Signed-off-by: Sasha Levin +--- + arch/x86/include/asm/mce.h | 1 + + arch/x86/kernel/cpu/mce/core.c | 11 ++++++++--- + 2 files changed, 9 insertions(+), 3 deletions(-) + +diff --git a/arch/x86/include/asm/mce.h b/arch/x86/include/asm/mce.h +index ddfb3cad8dff..2a8319fad0b7 100644 +--- a/arch/x86/include/asm/mce.h ++++ b/arch/x86/include/asm/mce.h +@@ -265,6 +265,7 @@ enum mcp_flags { + MCP_TIMESTAMP = BIT(0), /* log time stamp */ + MCP_UC = BIT(1), /* log uncorrected errors */ + MCP_DONTLOG = BIT(2), /* only clear, don't log */ ++ MCP_QUEUE_LOG = BIT(3), /* only queue to genpool */ + }; + bool machine_check_poll(enum mcp_flags flags, mce_banks_t *b); + +diff --git a/arch/x86/kernel/cpu/mce/core.c b/arch/x86/kernel/cpu/mce/core.c +index bf7fe87a7e88..01ff4014b7f6 100644 +--- a/arch/x86/kernel/cpu/mce/core.c ++++ b/arch/x86/kernel/cpu/mce/core.c +@@ -817,7 +817,10 @@ log_it: + if (mca_cfg.dont_log_ce && !mce_usable_address(&m)) + goto clear_it; + +- mce_log(&m); ++ if (flags & MCP_QUEUE_LOG) ++ mce_gen_pool_add(&m); ++ else ++ mce_log(&m); + + clear_it: + /* +@@ -1630,10 +1633,12 @@ static void __mcheck_cpu_init_generic(void) + m_fl = MCP_DONTLOG; + + /* +- * Log the machine checks left over from the previous reset. ++ * Log the machine checks left over from the previous reset.
