2020-05-19arm64: dts: rockchip: fix pd_tcpc0 and pd_tcpc1 node position on rk3399Johan Jonker
The pd_tcpc0 and pd_tcpc1 nodes are currently a sub node of pd_vio. In the rk3399 TRM figure of the 'Power Domain Partition' and in the table of 'Power Domain and Voltage Domain Summary' these power domains are positioned directly under VD_LOGIC, so fix that in 'rk3399.dtsi'.

2020-05-19arm64: dts: rockchip: add bus-width properties to mmc nodes for px30Johan Jonker

The mmc-controller.yaml didn't explicitly say disable-wp is for SD card slot only, but that is what it was designed for in the first place. Remove all disable-wp from emmc or sdio controllers.

2020-05-19arm64: dts: rockchip: rename and label gpio-led subnodesJohan Jonker
Current dts files with 'gpio-led' nodes were manually verified. In order to automate this process leds-gpio.txt has been converted to yaml. With this conversion a check for pattern properties was added. A test with the command below gives a screen full of warnings like: arch/arm64/boot/dts/rockchip/rk3368-r88.dt.yaml: gpio-leds: 'work' does not match any of the regexes: '(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+' Fix these errors with help of the following rules: 1: Add nodename in the preferred form. 2: Always add a label that ends with '_led' to prevent conflicts with other labels such as 'power' and 'mmc' 3: If leds need pinctrl add a label that ends with '_led_pin' also to prevent conflicts with other labels. patternProperties: # The first form is preferred, but fall back to just 'led' # anywhere in the node name to at least catch some child nodes.

2020-04-12MAINTAINERS: sort field names for all entriesLinus Torvalds
This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release. This was entirely scripted: ./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order Requested-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2020-04-12MAINTAINERS: sort entries by entry nameLinus Torvalds
They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

2020-04-11KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guestXiaoyao Li
Two types of #AC can be generated in Intel CPUs: 1. legacy alignment check #AC 2. split lock #AC Reflect #AC back into the guest if the guest has legacy alignment checks enabled or if split lock detection is disabled. If the #AC is not a legacy one and split lock detection is enabled, then invoke handle_guest_split_lock() which will either warn and disable split lock detection for this task or force SIGBUS on it.

2020-04-11KVM: x86: Emulate split-lock access as a write in emulatorXiaoyao Li
Emulate split-lock accesses as writes if split lock detection is on to avoid #AC during emulation, which will result in a panic(). This should never occur for a well-behaved guest, but a malicious guest can manipulate the TLB to trigger emulation of a locked instruction[1]. More discussion can be found at [2][3].

2020-04-11x86/split_lock: Provide handle_guest_split_lock()Thomas Gleixner
Without at least minimal handling for split lock detection induced #AC, VMX will just run into the same problem as the VMWare hypervisor, which was reported by Kenneth. It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a warning, disable SLD and mark the task accordingly. Otherwise force SIGBUS.

2020-04-10fs/seq_file.c: seq_read(): add info message about buggy .next functionsVasily Averin
Patch series "seq_file .next functions should increase position index". In Aug 2018 NeilBrown noticed commit 1f4aace60b0e ("fs/seq_file.c: simplify seq_file iteration code and interface") "Some ->next functions do not increment *pos when they return NULL... Note that such ->next functions are buggy and should be fixed. A simple demonstration is dd if=/proc/swaps bs=1000 skip=1 Choose any block size larger than the size of /proc/swaps. This will always show the whole last line of /proc/swaps" Described problem is still actual. If you make lseek into middle of last output line following read will output end of last line and whole last line once again. $ dd if=/proc/swaps bs=1 # usual output Filename Type Size Used Priority /dev/dm-0 partition 4194812 97536 -2 104+0 records in 104+0 records out 104 bytes copied $ dd if=/proc/swaps bs=40 skip=1 # last line was generated twice dd: /proc/swaps: cannot skip to specified offset v/dm-0 partition 4194812 97536 -2 /dev/dm-0 partition 4194812 97536 -2 3+1 records in 3+1 records out 131 bytes copied There are lot of other affected files, I've found 30+ including /proc/net/ip_tables_matches and /proc/sysvipc/* I've sent patches into maillists of affected subsystems already, this patch-set fixes the problem in files related to pstore, tracing, gcov, sysvipc and other subsystems processed via linux-kernel@ mailing list directly https://bugzilla.kernel.org/show_bug.cgi?id=206283 This patch (of 4): Add debug code to seq_read() to detect missed or out-of-tree incorrect .next seq_file functions.
