2019-12-06ARM: 8947/1: Fix __arch_get_hw_counter() access to CNTVCTVincenzo Frascino1-0/+3
__arch_get_hw_counter() should check clock_mode to see if it can access CNTVCT. With the conversion to unified vDSO this check has been left out. This causes on imx v6 and v7 (imx_v6_v7_defconfig) and other platforms to hang at boot during the execution of the init process as per below: [ 19.976852] Run /sbin/init as init process [ 20.044931] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 Fix the problem verifying that clock_mode is set coherently before accessing CNTVCT.

2019-12-06ARM: 8943/1: Fix topology setup in case of CPU hotplug for CONFIG_SCHED_MCDietmar Eggemann2-5/+9
Commit ca74b316df96 ("arm: Use common cpu_topology structure and functions.") changed cpu_coregroup_mask() from the ARM32 specific implementation in arch/arm/include/asm/topology.h to the one shared with ARM64 and RISCV in drivers/base/arch_topology.c. Currently on ARM32 (TC2 w/ CONFIG_SCHED_MC) the task scheduler setup code (w/ CONFIG_SCHED_DEBUG) shows this during CPU hotplug: ERROR: groups don't span domain->span It happens to CPUs of the cluster of the CPU which gets hot-plugged out on scheduler domain MC. Turns out that the shared cpu_coregroup_mask() requires that the hot-plugged CPU is removed from the core_sibling mask via remove_cpu_topology(). Otherwise the 'is core_sibling subset of cpumask_of_node()' doesn't work. In this case the task scheduler has to deal with cpumask_of_node instead of core_sibling which is wrong on scheduler domain MC. e.g. CPU3 hot-plugged out on TC2 [cluster0: 0,3-4 cluster1: 1-2]: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,3-4 ^ should be: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,4 Add remove_cpu_topology() to __cpu_disable() to remove the CPU from the topology masks in case of a CPU hotplug out operation. At the same time tweak store_cpu_topology() slightly so it will call update_siblings_masks() in case of CPU hotplug in operation via secondary_start_kernel()->smp_store_cpu_info(). This aligns the ARM32 implementation with the ARM64 one. Guarding remove_cpu_topology() with CONFIG_GENERIC_ARCH_TOPOLOGY is necessary since some Arm32 defconfigs (aspeed_g5_defconfig, milbeaut_m10v_defconfig, spear13xx_defconfig) specify an explicit # CONFIG_ARM_CPU_TOPOLOGY is not set w/ ./arch/arm/Kconfig: select GENERIC_ARCH_TOPOLOGY if ARM_CPU_TOPOLOGY Fixes: ca74b316df96 ("arm: Use common cpu_topology structure and functions") Reviewed-by: Sudeep Holla <[email protected]> Reviewed-by: Lukasz Luba <[email protected]> Tested-by: Lukasz Luba <[email protected]> Tested-by: Ondrej Jirman <[email protected]> Signed-off-by: Dietmar Eggemann <[email protected]> Signed-off-by: Russell King <[email protected]>

Merge two fixes for the pipe rework from David Howells: "Here are a couple of patches to fix bugs syzbot found in the pipe changes: - An assertion check will sometimes trip when polling a pipe because the ring size and indices used are approximate and may be being changed simultaneously. An equivalent approximate calculation was done previously, but without the assertion check, so I've just dropped the check. To make it accurate, the pipe mutex would need to be taken or the spin lock could be used - but usage of the spinlock would need to be rolled out into splice, iov_iter and other places for that. - The index mask and the max_usage values cannot be cached across pipe_wait() as F_SETPIPE_SZ could have been called during the wait.

2019-12-05pipe: Fix missing mask update after pipe_wait()David Howells1-6/+6
Fix pipe_write() to not cache the ring index mask and max_usage as their values are invalidated by calling pipe_wait() because the latter function drops the pipe lock, thereby allowing F_SETPIPE_SZ change them. Without this, pipe_write() may subsequently miscalculate the array indices and pipe fullness, leading to an oops like the following: BUG: KASAN: slab-out-of-bounds in pipe_write+0xc25/0xe10 fs/pipe.c:481 Write of size 8 at addr ffff8880771167a8 by task syz-executor.3/7987 ...

2019-12-05pipe: Remove assertion from pipe_poll()David Howells1-2/+1
An assertion check was added to pipe_poll() to make sure that the ring occupancy isn't seen to overflow the ring size. However, since no locks are held when the three values are read, it is possible for F_SETPIPE_SZ to intervene and muck up the calculation, thereby causing the oops. Fix this by simply removing the assertion and accepting that the calculation might be approximate. Note that the previous code also had a similar issue, though there was no assertion check, since the occupancy counter and the ring size were not read with a lock held, so it's possible that the poll check might have malfunctioned then too. Also wake up all the waiters so that they can reissue their checks if there was a competing read or write.

Currently, hns3_nic_maybe_stop_tx() uses skb_copy() to linearize a SKB if the BD num required by the SKB does not meet the hardware limitation, and it linearizes the SKB by allocating a new linearized SKB and freeing the old SKB, if hns3_nic_maybe_stop_tx() returns -EBUSY because there are no enough space in the ring to send the linearized skb to hardware, the sch_direct_xmit() still hold reference to old SKB and try to retransmit the old SKB when dev_hard_start_xmit() return TX_BUSY, which may cause use after freed problem.

This patch fixes it by rechecking the ring_space after netif_stop_subqueue to make sure TX queue is restarted. Also, the ring->next_to_clean is updated even when pkts is zero, because all the TX BD cleaned may be non-SKB, so it needs to check if TX queue need to be restarted.

2019-12-05net/mlx5e: Fix TXQ indices to be sequentialEran Ben Elisha4-22/+15
Cited patch changed (channel index, tc) => (TXQ index) mapping to be a static one, in order to keep indices consistent when changing number of channels or TCs. For 32 channels (OOB) and 8 TCs, real num of TXQs is 256. When reducing the amount of channels to 8, the real num of TXQs will be changed to 64. This indices method is buggy: - Channel #0, TC 3, the TXQ index is 96. - Index 8 is not valid, as there is no such TXQ from driver perspective (As it represents channel #8, TC 0, which is not valid with the above configuration). As part of driver's select queue, it calls netdev_pick_tx which returns an index in the range of real number of TXQs. Depends on the return value, with the examples above, driver could have returned index larger than the real number of tx queues, or crash the kernel as it tries to read invalid address of SQ which was not allocated. Fix that by allocating sequential TXQ indices, and hold a new mapping between (channel index, tc) => (real TXQ index). This mapping will be updated as part of priv channels activation, and is used in mlx5e_select_queue to find the selected queue index. The existing indices mapping (channel_tc2txq) is no longer needed, as it is used only for statistics structures and can be calculated on run time. Delete its definintion and updates.

2019-12-05s390/qeth: fix dangling IO buffers after halt/clearJulian Wiedmann5-46/+67
The cio layer's intparm logic does not align itself well with how qeth manages cmd IOs. When an active IO gets terminated via halt/clear, the corresponding IRQ's intparm does not reflect the cmd buffer but rather the intparm that was passed to ccw_device_halt() / ccw_device_clear(). This behaviour was recently clarified in commit b91d9e67e50b ("s390/cio: fix intparm documentation"). As a result, qeth_irq() currently doesn't cancel a cmd that was terminated via halt/clear. This primarily causes us to leak card->read_cmd after the qeth device is removed, since our IO path still holds a refcount for this cmd. For qeth this means that we need to keep track of which IO is pending on a device ('active_cmd'), and use this as the intparm when calling halt/clear. Otherwise qeth_irq() can't match the subsequent IRQ to its cmd buffer. Since we now keep track of the _expected_ intparm, we can also detect any mismatch; this would constitute a bug somewhere in the lower layers. In this case cancel the active cmd - we effectively "lost" the IRQ and should not expect any further notification for this IO.

2019-12-05s390/qeth: ensure linear access to packet headersJulian Wiedmann1-33/+31
When the RX path builds non-linear skbs, the packet headers can currently spill over into page fragments. Depending on the packet type and what fields we need to access in the headers, this could cause us to go past the end of skb->data. So for non-linear packets, copy precisely the length of the necessary headers ('linear_len') into skb->data. And don't copy more, upper-level protocols will peel whatever additional packet headers they need.

2019-12-05s390/qeth: guard against runt packetsJulian Wiedmann3-6/+23
Depending on a packet's type, the RX path needs to access fields in the packet headers and thus requires a minimum packet length. Enforce this length when building the skb. On the other hand a single runt packet is no reason to drop the whole RX buffer. So just skip it, and continue processing on the next packet.

Call phy_start() before calling phy_start_aneg() during probe so that autonegotiation is initiated. As phy_start() takes care of calling phy_start_aneg(), drop the explicit call to phy_start_aneg().

hsr_dev_xmit() calls hsr_port_get_hsr() to find master node and that would return NULL if master node is not existing in the list. But hsr_dev_xmit() doesn't check return pointer so a NULL dereference could occur.

7c20f11680a4 ("bio-integrity: stop abusing bi_end_io") moves bio_integrity_free from bio_uninit() to bio_integrity_verify_fn() and bio_endio(). This way looks wrong because bio may be freed without calling bio_endio(), for example, blk_rq_unprep_clone() is called from dm_mq_queue_rq() when the underlying queue of dm-mpath is busy. So memory leak of bio integrity data is caused by commit 7c20f11680a4. Fixes this issue by re-adding bio_integrity_free() to bio_uninit().
