[ Upstream commit 9bbce32a20d6a72c767a7f85fd6127babd1410ac ]
Without DT aliases, the numbering of mmc interfaces is unpredictable. Adding them makes it possible to refer to devices consistently. The popular suggestion to use UUIDs obviously doesn't work with a blank device fresh from the factory.
See commit fa2d0aa96941 ("mmc: core: Allow setting slot index via device tree alias") for more discussion.

[ Upstream commit 0571a753cb07982cc82f4a5115e0b321da89e1f3 ]
pxa168_eth_remove() firstly calls unregister_netdev(), then cancels a timeout work. unregister_netdev() shuts down a device interface and removes it from the kernel tables. If the timeout occurs in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop and open of the device. It may lead to an inconsistent state and memory leaks.

[ Upstream commit 3d677f12ea3a2097a16ded570623567403dea959 ]
On many recent ThinkPad laptops, there's a new LED next to the ESC key, that indicates the FnLock status. When the Fn+ESC combo is pressed, FnLock is toggled, which causes the Media Key functionality to change, making it so that the media keys either perform their media key function, or function as an F-key by default. The Fn key can be used the access the alternate function at any time.
With the current linux kernel, the LED doens't change state if you press the Fn+ESC key combo. However, the media key functionality *does* change. This is annoying, since the LED will stay on if it was on during bootup, and it makes it hard to keep track what the current state of the FnLock is.
This patch calls an ACPI function, that gets the current media key state, when the Fn+ESC key combo is pressed. Through testing it was discovered that this function causes the LED to update correctly to reflect the current state when this function is called.
The relevant ACPI calls are the following: _SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled. _SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

RHBZ: 1933527
Under SMB1 + POSIX, if an inode is reused on a server after we have read and cached a part of a file, when we then open the new file with the re-cycled inode there is a chance that we may serve the old data out of cache to the application. This only happens for SMB1 (deprecated) and when posix are used. The simplest solution to avoid this race is to force a revalidate on smb1-posix open.

Make SMB2 not print out an error when an oplock break is received for an unknown handle, similar to SMB1. The debug message which is printed for these unknown handles may also be misleading, so fix that too.
The SMB2 lease break path is not affected by this patch.

commit e4d4d456436bfb2fe412ee2cd489f7658449b098 upstream.
The branch displacement logic in the BPF JIT compilers for x86 assumes that, for any generated branch instruction, the distance cannot increase between optimization passes.
But this assumption can be violated due to how the distances are computed. Specifically, whenever a backward branch is processed in do_jit(), the distance is computed by subtracting the positions in the machine code from different optimization passes. This is because part of addrs[] is already updated for the current optimization pass, before the branch instruction is visited.
And so the optimizer can expand blocks of machine code in some cases.
This can confuse the optimizer logic, where it assumes that a fixed point has been reached for all machine code blocks once the total program size stops changing. And then the JIT compiler can output abnormal machine code containing incorrect branch displacements.
To mitigate this issue, we assert that a fixed point is reached while populating the output image. This rejects any problematic programs. The issue affects both x86-32 and x86-64. We mitigate separately to ease backporting.

commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream.
While allmodconfig and allyesconfig build for s390 there are also various bots running compile tests with randconfig, where PCI is disabled. This reveals that a lot of drivers should actually depend on HAS_IOMEM. Adding this to each device driver would be a never ending story, therefore just disable COMPILE_TEST for s390.
The reasoning is more or less the same as described in commit bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML").

From: Masahiro Yamada masahiroy@kernel.org
commit ea29b20a828511de3348334e529a3d046a180416 upstream.
I read the commit log of the following two:
- bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML") - 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390")
Both are talking about HAS_IOMEM dependency missing in many drivers.
So, 'depends on HAS_IOMEM' seems the direct, sensible solution to me.
This does not change the behavior of UML. UML still cannot enable COMPILE_TEST because it does not provide HAS_IOMEM.
The current dependency for S390 is too strong. Under the condition of CONFIG_PCI=y, S390 provides HAS_IOMEM, hence can enable COMPILE_TEST.
I also removed the meaningless 'default n'.

Having said this, I did see a spurious crash, and I see an unusual warning. I have seen the crash only once, but the warning happens with every boot. These are likely not new but exposed because I added network interface tests. This is all v4.14.y specific; I did not see it in other branches. See below for the tracebacks. Maybe someone has seen it before.
Thanks, Guenter

Hmm, turns out those are a bit more severe than I thought. The fix for both the crash and the warning is commit 062b3e1b6d4f ("net/ncsi: Refactor MAC, VLAN filters"). Unfortunately, that commit does not apply on its own. The following sequence of commits on top of v4.14.y fixes the problem for me.

Having said this, I did see a spurious crash, and I see an unusual warning. I have seen the crash only once, but the warning happens with every boot. These are likely not new but exposed because I added network interface tests. This is all v4.14.y specific; I did not see it in other branches. See below for the tracebacks. Maybe someone has seen it before.
I do not notice these warnings. Please share the testing environment / device / setup / network interfaces and Kernel configs and steps to reproduce.

Hi Naresh,
the configuration is based on aspeed_g5_defconfig (see attached configuration file) and the following qemu command line (qemu v5.2):
qemu-system-arm -M romulus-bmc -kernel \ arch/arm/boot/zImage -no-reboot \ -initrd rootfs-armv5.cpio -nic user -nodefaults \ --append "panic=-1 slub_debug=FZPUA rdinit=/sbin/init console=ttyS4,115200 earlycon=uart8250,mmio32,0x1e784000,115200n8" \ -dtb arch/arm/boot/dts/aspeed-bmc-opp-romulus.dtb \ -nographic -monitor null -serial stdio
It also happens with other bmc platforms using the same network interface, though it is for some reason more prevalent on romulus-bmc.
The root file system is generated with buildroot. See buildone.sh / buildall.sh in branch local-2021.02 of git@github.com:groeck/buildroot.git. The warning happens with almost every boot; the crash in maybe one of 5-10 boots. The test, if you want to call it that, uses udhcpc to get an IP address and then
net_test_successful=0 ifconfig eth0 2>/dev/null | grep -q "inet addr:10.0.2.15" if [ $? -eq 0 ]; then ping -q -c 1 -s 1000 -W 1 -I eth0 10.0.2.2 >/dev/null if [ $? -eq 0 ]; then telnet 10.0.2.2:22 </dev/null >/dev/null 2>dev/null if [ $? -eq 0 ]; then net_test_successful=1 fi fi fi
See package/busybox/run.sh in the above repository/branch.

Thanks for testing all of these, I'll go queue up your reported fixes here for the next release.

You'll need one more patch to avoid yet another warning:
b0949618826c net/ncsi: Avoid GFP_KERNEL in response handler
Thanks, Guenter
