2018-07-05drm/udl: fix display corruption of the last lineMikulas Patocka2-5/+11
The displaylink hardware has such a peculiarity that it doesn't render a command until next command is received. This produces occasional corruption, such as when setting 22x11 font on the console, only the first line of the cursor will be blinking if the cursor is located at some specific columns. When we end up with a repeating pixel, the driver has a bug that it leaves one uninitialized byte after the command (and this byte is enough to flush the command and render it - thus it fixes the screen corruption), however whe we end up with a non-repeating pixel, there is no byte appended and this results in temporary screen corruption. This patch fixes the screen corruption by always appending a byte 0xAF at the end of URB. It also removes the uninitialized byte.

A hooking API was implemented for 4.17 in fa93854f7a7ed63d followed by hooks for Thinkpad laptops in 2801b9683f740012. The Thinkpad drivers did not support the Thinkpad 13 and the hooking API crashes on unsupported batteries by altering a list of hooks during unsafe iteration. Thus, Thinkpad 13 laptops could no longer boot. Additionally, a lock was kept in place and debugging information was printed out of order.

2018-07-03PM / Domains: Don't power on at attach for the multi PM domain caseUlf Hansson1-7/+9
There are no legacy behavior in drivers to consider while attaching a device to genpd - for the multiple PM domain case. For that reason, let's instead require the driver to runtime resume the device, via calling pm_runtime_get_sync() for example, when it needs to power on the corresponding PM domain. This allows us to improve the situation during attach. Instead of always power on the PM domain, which may be unnecessary, let's leave it in its current state. Additionally, to avoid the PM domain to stay powered on, let's schedule a power off work. Fixes: 3c095f32a92b (PM / Domains: Add support for multi PM domains ...)

Currently, we use the ACPI processor ID only for the leaf/processor nodes as the specification states it must match the value of the ACPI processor ID field in the processor’s entry in the MADT. However, if a PPTT structure represents a processors group, it matches a processor container UID in the namespace and the ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the ACPI processor ID is valid. Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be consistent instead of using table offset as it's currently done for non-leaf nodes.

2018-07-02drbd: fix access after freeLars Ellenberg1-1/+1
We have struct drbd_requests { ... struct bio *private_bio; ... } to hold a bio clone for local submission. On local IO completion, we put that bio, and in case we want to use the result later, we overload that member to hold the ERR_PTR() of the completion result, Which, before v4.3, used to be the passed in "int error", so we could first bio_put(), then assign. v4.3-rc1~100^2~21 4246a0b63bd8 block: add a bi_error field to struct bio changed that: bio_put(req->private_bio); - req->private_bio = ERR_PTR(error); + req->private_bio = ERR_PTR(bio->bi_error); Which introduces an access after free, because it was non obvious that req->private_bio == bio. Impact of that was mostly unnoticable, because we only use that value in a multiple-failure case, and even then map any "unexpected" error code to EIO, so worst case we could potentially mask a more specific error with EIO in a multiple failure case. Unless the pointed to memory region was unmapped, as is the case with CONFIG_DEBUG_PAGEALLOC, in which case this results in BUG: unable to handle kernel paging request v4.13-rc1~70^2~75 4e4cbee93d56 block: switch bios to blk_status_t changes it further to bio_put(req->private_bio); req->private_bio = ERR_PTR(blk_status_to_errno(bio->bi_status)); And blk_status_to_errno() now contains a WARN_ON_ONCE() for unexpected values, which catches this "sometimes", if the memory has been reused quickly enough for other things. Should also go into stable since 4.3, with the trivial change around 4.13.

2018-07-02ipvlan: call dev_change_flags when ipvlan mode is resetHangbin Liu1-8/+28
After we change the ipvlan mode from l3 to l2, or vice versa, we only reset IFF_NOARP flag, but don't flush the ARP table cache, which will cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2(). Then the message will not come out of host. Here is the reproducer on local host: ip link set eth1 up ip addr add 192.168.1.1/24 dev eth1 ip link add link eth1 ipvlan1 type ipvlan mode l3 ip netns add net1 ip link set ipvlan1 netns net1 ip netns exec net1 ip link set ipvlan1 up ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1 ip route add 192.168.2.0/24 via 192.168.1.2 ping 192.168.2.2 -c 2 ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2 ping 192.168.2.2 -c 2 Add the same configuration on remote host. After we set the mode to l2, we could find that the src/dst MAC addresses are the same on eth1: 21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64 Fix this by calling dev_change_flags(), which will call netdevice notifier with flag change info. v2: a) As pointed out by Wang Cong, check return value for dev_change_flags() when change dev flags. b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops. So we don't need to redo ipvlan_{, un}register_nf_hook() again in err path.

2018-07-02net: fix use-after-free in GRO with ESPSabrina Dubroca2-4/+2
Since the addition of GRO for ESP, gro_receive can consume the skb and return -EINPROGRESS. In that case, the lower layer GRO handler cannot touch the skb anymore. Commit 5f114163f2f5 ("net: Add a skb_gro_flush_final helper.") converted some of the gro_receive handlers that can lead to ESP's gro_receive so that they wouldn't access the skb when -EINPROGRESS is returned, but missed other spots, mainly in tunneling protocols. This patch finishes the conversion to using skb_gro_flush_final(), and adds a new helper, skb_gro_flush_final_remcsum(), used in VXLAN and GUE.

2018-07-02s390/dasd: reduce the default queue depth and nr of hardware queuesStefan Haberland2-10/+11
Reduce the default values for the number of hardware queues and queue depth to significantly reduce the memory footprint of a DASD device. The memory consumption per DASD device reduces from approximately 40MB to approximately 1.5MB. This is necessary to build systems with a large number of DASD devices and a reasonable amount of memory. Performance measurements showed that good performance results are possible with the new default values even on systems with lots of CPUs and lots of alias devices.

2018-07-02drm/i915/gvt: fix a bug of partially write ggtt entiesZhao Yan2-0/+60
when guest writes ggtt entries, it could write 8 bytes a time if gtt_entry_size is 8. But, qemu could split the 8 bytes into 2 consecutive 4-byte writes. If each 4-byte partial write could trigger a host ggtt write, it is very possible that a wrong combination is written to the host ggtt. E.g. the higher 4 bytes is the old value, but the lower 4 bytes is the new value, and this 8-byte combination is wrong but written to the ggtt, thus causing bugs. To handle this condition, we just record the first 4-byte write, then wait until the second 4-byte write comes and write the combined 64-bit data to host ggtt table. To save memory space and to spot partial write as early as possible, we don't keep this information for every ggtt index. Instread, we just record the last ggtt write position, and assume the two 4-byte writes come in consecutively for each vgpu. This assumption is right based on the characteristic of ggtt entry which stores memory address. When gtt_entry_size is 8, the guest memory physical address should be 64 bits, so any sane guest driver should write 8-byte long data at a time, so 2 consecutive 4-byte writes at the same ggtt index should be trapped in gvt. v2: when incomplete ggtt entry write is located, e.g. 1. guest only writes 4 bytes at a ggtt offset and no long writes the rest 4 bytes. 2. guest writes 4 bytes of a ggtt offset, then write at other ggtt offsets, then return back to write the left 4 bytes of the first ggtt offset. add error handling logic to remap host entry to scratch page, and mark guest virtual ggtt entry as not present.
