2019-11-04stacktrace: Don't skip first entry on noncurrent tasksJiri Slaby1-2/+4
When doing cat /proc/<PID>/stack, the output is missing the first entry. When the current code walks the stack starting in stack_trace_save_tsk, it skips all scheduler functions (that's OK) plus one more function. But this one function should be skipped only for the 'current' task as it is stack_trace_save_tsk proper. The original code (before the common infrastructure) skipped one function only for the 'current' task -- see save_stack_trace_tsk before 3599fe12a125. So do so also in the new infrastructure now.

2019-11-04netfilter: ipset: Copy the right MAC address in hash:ip,mac IPv6 setsStefano Brivio1-1/+1
Same as commit 1b4a75108d5b ("netfilter: ipset: Copy the right MAC address in bitmap:ip,mac and hash:ip,mac sets"), another copy and paste went wrong in commit 8cc4ccf58379 ("netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets"). When I fixed this for IPv4 in 1b4a75108d5b, I didn't realise that hash:ip,mac sets also support IPv6 as family, and this is covered by a separate function, hash_ipmac6_kadt(). In hash:ip,mac sets, the first dimension is the IP address, and the second dimension is the MAC address: check the IPSET_DIM_TWO_SRC flag in flags while deciding which MAC address to copy, destination or source. This way, mixing source and destination matches for the two dimensions of ip,mac hash type works as expected, also for IPv6. With this setup: ip netns add A ip link add veth1 type veth peer name veth2 netns A ip addr add 2001:db8::1/64 dev veth1 ip -net A addr add 2001:db8::2/64 dev veth2 ip link set veth1 up ip -net A link set veth2 up dst=$(ip netns exec A cat /sys/class/net/veth2/address) ip netns exec A ipset create test_hash hash:ip,mac family inet6 ip netns exec A ipset add test_hash 2001:db8::1,${dst} ip netns exec A ip6tables -A INPUT -p icmpv6 --icmpv6-type 135 -j ACCEPT ip netns exec A ip6tables -A INPUT -m set ! --match-set test_hash src,dst -j DROP ipset now correctly matches a test packet: # ping -c1 2001:db8::2 >/dev/null # echo $? 0 Reported-by: Chen, Yi <[email protected]> Fixes: 8cc4ccf58379 ("netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets") Signed-off-by: Stefano Brivio <[email protected]> Signed-off-by: Jozsef Kadlecsik <[email protected]>

Commit 3d8598fb9c5a ("clk: ti: clkctrl: use fallback udelay approach if timekeeping is suspended") added handling for cases when timekeeping is suspended. But looks like we can still get occasional "failed to enable" errors on the PM runtime resume path with udelay() returning faster than expected. With ti-sysc interconnect target module driver this leads into device failure with PM runtime failing with "failed to enable" clkctrl error. Let's fix the issue with a delay of two times the desired delay as in often done for udelay() to account for the inaccuracy.

2019-11-04ASoC: hdac_hda: fix race in device removalKai Vehmanen1-1/+1
When ASoC card instance is removed containing a HDA codec, hdac_hda_codec_remove() may run in parallel with codec resume. This will cause problems if the HDA link is freed with snd_hdac_ext_bus_link_put() while the codec is still in middle of its resume process. To fix this, change the order such that pm_runtime_disable() is called before the link is freed. This will ensure any pending runtime PM action is completed before proceeding to free the link. This issue can be easily hit with e.g. SOF driver by loading and unloading the drivers.

Saffire Pro i/o series For Focusrite Saffire Pro i/o, the lowest 8 bits of register represents configured source of sampling clock. The next lowest 8 bits represents whether the configured source is actually detected or not just after the register is changed for the source. Current implementation evaluates whole the register to detect configured source. This results in failure due to the next lowest 8 bits when the source is connected in advance.

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v5.5-rc1 The bulk of these changes is the addition of DisplayPort support for Tegra210, Tegra186 and Tegra194. I've been running versions of this for about three years now, so I'd consider these changes to be pretty mature. These changes also unify the existing eDP support with the DP support since the programming is very similar, except for a few steps that can be easily parameterized. The rest are a couple of fixes all over the place for minor issues, as well as some work to support the IOMMU-backed DMA API, which in the end turned out to also clean up a number of cases where the DMA API was not being used correctly.

2019-11-03Revert "gpio: merrifield: Pass irqchip when adding gpiochip"Linus Walleij1-16/+12
This reverts commit 8f86a5b4ad679e4836733b47414226074eee4e4d. It has been established that this causes a boot regression on both Baytrail and Cherrytrail SoCs, and we can't have that in the final kernel release, so we need to revert it.

2019-11-03x86/resctrl: Prevent NULL pointer dereference when reading mondataXiaochen Shen1-0/+4
When a mon group is being deleted, rdtgrp->flags is set to RDT_DELETED in rdtgroup_rmdir_mon() firstly. The structure of rdtgrp will be freed until rdtgrp->waitcount is dropped to 0 in rdtgroup_kn_unlock() later. During the window of deleting a mon group, if an application calls rdtgroup_mondata_show() to read mondata under this mon group, 'rdtgrp' returned from rdtgroup_kn_lock_live() is a NULL pointer when rdtgrp->flags is RDT_DELETED. And then 'rdtgrp' is passed in this path: rdtgroup_mondata_show() --> mon_event_read() --> mon_event_count(). Thus it results in NULL pointer dereference in mon_event_count(). Check 'rdtgrp' in rdtgroup_mondata_show(), and return -ENOENT immediately when reading mondata during the window of deleting a mon group.

2019-11-03idr: Fix idr_alloc_u32 on 32-bit systemsMatthew Wilcox (Oracle)1-1/+1
Attempting to allocate an entry at 0xffffffff when one is already present would succeed in allocating one at 2^32, which would confuse everything. Return -ENOSPC in this case, as expected. Signed-off-by: Matthew Wilcox (Oracle) <[email protected]>
2019-11-03idr: Fix integer overflow in idr_for_each_entryMatthew Wilcox (Oracle)1-1/+1
If there is an entry at INT_MAX then idr_for_each_entry() will increment id after handling it. This is undefined behaviour, and is caught by UBSAN. Adding 1U to id forces the operation to be carried out as an unsigned addition which (when assigned to id) will result in INT_MIN. Since there is never an entry stored at INT_MIN, idr_get_next() will return NULL, ending the loop as expected. Signed-off-by: Matthew Wilcox (Oracle) <[email protected]>

2019-11-02HID: i2c-hid: Send power-on command after resetHans de Goede1-0/+4
Before commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"), any i2c-hid touchscreens would typically be runtime-suspended between the driver loading and Xorg or a Wayland compositor opening it, causing it to be resumed again. This means that before this change, we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the graphical session would start listening to the touchscreen. It turns out that at least some SIS touchscreens, such as the one found on the Asus T100HA, need a power-on command after reset, otherwise they will not send any events.

The "secure virtual machine" support we added in v5.4 had a bug if the kernel was relocated (moved during boot), in those cases the signature of the kernel text wouldn't verify and the Ultravisor would refuse to run the VM. A recent change to disable interrupts before calling arch_cpu_idle_dead() caused a WARN_ON() in our bare metal CPU offline code to always trigger. The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the address range crossed a segment (256MB) boundary which could lead to spurious faults.
