This reverts commit b03755ad6f.
This is sad, and done for all the wrong reasons. Because that commit is
good, and does exactly what it says: avoids a lot of small disk requests
for the inode table read-ahead.
However, it turns out that it causes an entirely unrelated problem: the
getrandom() system call was introduced back in 2014 by commit
c6e9d6f388 ("random: introduce getrandom(2) system call"), and people
use it as a convenient source of good random numbers.
But part of the current semantics for getrandom() is that it waits for
the entropy pool to fill at least partially (unlike /dev/urandom). And
at least ArchLinux apparently has a systemd that uses getrandom() at
boot time, and the improvements in IO patterns means that existing
installations suddenly start hanging, waiting for entropy that will
never happen.
It seems to be an unlucky combination of not _quite_ enough entropy,
together with a particular systemd version and configuration. Lennart
says that the systemd-random-seed process (which is what does this early
access) is supposed to not block any other boot activity, but sadly that
doesn't actually seem to be the case (possibly due bogus dependencies on
cryptsetup for encrypted swapspace).
The correct fix is to fix getrandom() to not block when it's not
appropriate, but that fix is going to take a lot more discussion. Do we
just make it act like /dev/urandom by default, and add a new flag for
"wait for entropy"? Do we add a boot-time option? Or do we just limit
the amount of time it will wait for entropy?
So in the meantime, we do the revert to give us time to discuss the
eventual fix for the fundamental problem, at which point we can re-apply
the ext4 inode table access optimization.

Last week, Palmer and I learned that there was an error in the RISC-V
kernel image header format that could make it less compatible with the
ARM64 kernel image header format. I had missed this error during my
original reviews of the patch.
The kernel image header format is an interface that impacts
bootloaders, QEMU, and other user tools. Those packages must be
updated to align with whatever is merged in the kernel. We would like
to avoid proliferating these image formats by keeping the RISC-V
header as close as possible to the existing ARM64 header. Since the
arch/riscv patch that adds support for the image header was merged
with our v5.3-rc1 pull request as commit 0f327f2aaa ("RISC-V: Add
an Image header that boot loader can parse."), we think it wise to try
to fix this error before v5.3 is released.
The fix itself should be backwards-compatible with any project that
has already merged support for premature versions of this interface.
It primarily involves ensuring that the RISC-V image header has
something useful in the same field as the ARM64 image header.

KVM: s390: Fixes for 5.3
- prevent a user triggerable oops in the migration code
- do not leak kernel stack content
James Harvey reported a livelock that was introduced by commit
d012a06ab1 ("Revert "KVM: x86/mmu: Zap only the relevant pages when
removing a memslot"").
The livelock occurs because kvm_mmu_zap_all() as it exists today will
voluntarily reschedule and drop KVM's mmu_lock, which allows other vCPUs
to add shadow pages. With enough vCPUs, kvm_mmu_zap_all() can get stuck
in an infinite loop as it can never zap all pages before observing lock
contention or the need to reschedule. The equivalent of kvm_mmu_zap_all()
that was in use at the time of the reverted commit (4e103134b8, "KVM:
x86/mmu: Zap only the relevant pages when removing a memslot") employed
a fast invalidate mechanism and was not susceptible to the above livelock.
There are three ways to fix the livelock:
- Reverting the revert (commit d012a06ab1) is not a viable option as
the revert is needed to fix a regression that occurs when the guest has
one or more assigned devices. It's unlikely we'll root cause the device
assignment regression soon enough to fix the regression timely.
- Remove the conditional reschedule from kvm_mmu_zap_all(). However, although
removing the reschedule would be a smaller code change, it's less safe
in the sense that the resulting kvm_mmu_zap_all() hasn't been used in
the wild for flushing memslots since the fast invalidate mechanism was
introduced by commit 6ca18b6950 ("KVM: x86: use the fast way to
invalidate all pages"), back in 2013.
- Reintroduce the fast invalidate mechanism and use it when zapping shadow
pages in response to a memslot being deleted/moved, which is what this
patch does.
For all intents and purposes, this is a revert of commit ea145aacf4
("Revert "KVM: MMU: fast invalidate all pages"") and a partial revert of
commit 7390de1e99 ("Revert "KVM: x86: use the fast way to invalidate
all pages""), i.e. restores the behavior of commit 5304b8d37c ("KVM:
MMU: fast invalidate all pages") and commit 6ca18b6950 ("KVM: x86:
use the fast way to invalidate all pages") respectively.

Emulation of VMPTRST can incorrectly inject a page fault
when passed an operand that points to an MMIO address.
The page fault will use uninitialized kernel stack memory
as the CR2 and error code.
The right behavior would be to abort the VM with a KVM_EXIT_INTERNAL_ERROR
exit to userspace; however, it is not an easy fix, so for now just ensure
that the error code and CR2 are zero.

Part of the intention during the definition of the RISC-V kernel image
header was to lay the groundwork for a future merge with the ARM64
image header. One error during my original review was not noticing
that the RISC-V header's "magic" field was at a different size and
position than the ARM64's "magic" field. If the existing ARM64 Image
header parsing code were to attempt to parse an existing RISC-V kernel
image header format, it would see a magic number 0. This is
undesirable, since it's our intention to align as closely as possible
with the ARM64 header format. Another problem was that the original
"res3" field was not being initialized correctly to zero.
Address these issues by creating a 32-bit "magic2" field in the RISC-V
header which matches the ARM64 "magic" field. RISC-V binaries will
store "RSC\x05" in this field. The intention is that the use of the
existing 64-bit "magic" field in the RISC-V header will be deprecated
over time. Increment the minor version number of the file format to
indicate this change, and update the documentation accordingly. Fix
the assembler directives in head.S to ensure that reserved fields are
properly zero-initialized.

A Mediatek based smartphone owner reports problems with USB
tethering in Linux. The verbose USB listing shows a rndis_host
interface pair (e0/01/03 + 10/00/00), but the driver fails to
bind with
[ 355.960428] usb 1-4: bad CDC descriptors
The problem is a failsafe test intended to filter out ACM serial
functions using the same 02/02/ff class/subclass/protocol as RNDIS.
The serial functions are recognized by their non-zero bmCapabilities.
No RNDIS function with non-zero bmCapabilities were known at the time
this failsafe was added. But it turns out that some Wireless class
RNDIS functions are using the bmCapabilities field. These functions
are uniquely identified as RNDIS by their class/subclass/protocol, so
the failing test can safely be disabled. The same applies to the two
types of Misc class RNDIS functions.
Applying the failsafe to Communication class functions only retains
the original functionality, and fixes the problem for the Mediatek based
smartphone.
Tow examples of CDC functional descriptors with non-zero bmCapabilities
from Wireless class RNDIS functions are:
0e8d:000a Mediatek Crosscall Spider X5 3G Phone
CDC Header:
bcdCDC 1.10
CDC ACM:
bmCapabilities 0x0f

The Mediatek example is believed to apply to most smartphones with
Mediatek firmware. The ZTE example is most likely also part of a larger
family of devices/firmwares.

====================
fix memory leak for sctp_do_bind
First two patches are to do cleanup, remove redundant assignment,
and change return type of sctp_get_port_local.
Third patch is to fix memory leak for sctp_do_bind if failed
to bind address.
v2: add one patch to change return type of sctp_get_port_local.

There are more parentheses in if clause when call sctp_get_port_local
in sctp_do_bind, and redundant assignment to 'ret'. This patch is to
do cleanup.

Currently sctp_get_port_local() returns a long
which is either 0,1 or a pointer casted to long.
It's neither of the callers use the return value since
commit 62208f1245 ("net: sctp: simplify sctp_get_port").
Now two callers are sctp_get_port and sctp_do_bind,
they actually assumend a casted to an int was the same as
a pointer casted to a long, and they don't save the return
value just check whether it is zero or non-zero, so
it would better change return type from long to int for
sctp_get_port_local.

Port the same fix for ixgbe to ixgbevf.
The ixgbevf driver currently does IPsec Tx offloading
based on an existing secpath. However, the secpath
can also come from the Rx side, in this case it is
misinterpreted for Tx offload and the packets are
dropped with a "bad sa_idx" error. Fix this by using
the xfrm_offload() function to test for Tx offload.

Accessing the device when it may be runtime suspended is a bug, which is
the case in tmio_mmc_host_remove(). Let's fix the behaviour.
Cc: [email protected]
Signed-off-by: Ulf Hansson <[email protected]>
Tested-by: Geert Uytterhoeven <[email protected]>
The tmio_mmc_host_probe() calls pm_runtime_set_active() to update the
runtime PM status of the device, as to make it reflect the current status
of the HW. This works fine for most cases, but unfortunate not for all.
Especially, there is a generic problem when the device has a genpd attached
and that genpd have the ->start|stop() callbacks assigned.
More precisely, if the driver calls pm_runtime_set_active() during
->probe(), genpd does not get to invoke the ->start() callback for it,
which means the HW isn't really fully powered on. Furthermore, in the next
phase, when the device becomes runtime suspended, genpd will invoke the
->stop() callback for it, potentially leading to usage count imbalance
problems, depending on what's implemented behind the callbacks of course.
To fix this problem, convert to call pm_runtime_get_sync() from
tmio_mmc_host_probe() rather than pm_runtime_set_active(). Additionally, to
avoid bumping usage counters and unnecessary re-initializing the HW the
first time the tmio driver's ->runtime_resume() callback is called,
introduce a state flag to keeping track of this.

This reverts commit 7ff2131933.
It turns out that the above commit introduces other problems. For example,
calling pm_runtime_set_active() must not be done prior calling
pm_runtime_enable() as that makes it fail. This leads to additional
problems, such as clock enables being wrongly balanced.
Rather than fixing the problem on top, let's start over by doing a revert.

Pull btrfs fixes from David Sterba:
"Here are two fixes, one of them urgent fixing a bug introduced in 5.2
and reported by many users. It took time to identify the root cause,
catching the 5.3 release is higly desired also to push the fix to 5.2
stable tree.
The bug is a mess up of return values after adding proper error
handling and honestly the kind of bug that can cause sleeping
disorders until it's caught. My appologies to everybody who was
affected.
Summary of what could happen:
1) either a hang when committing a transaction, if this happens
there's no risk of corruption, still the hang is very inconvenient
and can't be resolved without a reboot
2) writeback for some btree nodes may never be started and we end up
committing a transaction without noticing that, this is really
serious and that will lead to the "parent transid verify failed"
messages"

If a new child cgroup is created in the frozen cgroup hierarchy
(one or more of ancestor cgroups is frozen), the CGRP_FREEZE cgroup
flag should be set. Otherwise if a process will be attached to the
child cgroup, it won't become frozen.
The problem can be reproduced with the test_cgfreezer_mkdir test.
This is the output before this patch:
~/test_freezer
ok 1 test_cgfreezer_simple
ok 2 test_cgfreezer_tree
ok 3 test_cgfreezer_forkbomb
Cgroup /sys/fs/cgroup/cg_test_mkdir_A/cg_test_mkdir_B isn't frozen
not ok 4 test_cgfreezer_mkdir
ok 5 test_cgfreezer_rmdir
ok 6 test_cgfreezer_migrate

Add a new cgroup freezer selftest, which checks that if a cgroup is
frozen, their new child cgroups will properly inherit the frozen
state.
It creates a parent cgroup, freezes it, creates a child cgroup
and populates it with a dummy process. Then it checks that both
parent and child cgroup are frozen.

Pull clone3 fix from Christian Brauner:
"This is a last-minute bugfix for clone3() that should go in before we
release 5.3 with clone3().
clone3() did not verify that the exit_signal argument was set to a
valid signal. This can be used to cause a crash by specifying a signal
greater than NSIG. e.g. -1.
The commit from Eugene adds a check to copy_clone_args_from_user() to
verify that the exit signal is limited by CSIGNAL as with legacy
clone() and that the signal is valid. With this we don't get the
legacy clone behavior were an invalid signal could be handed down and
would only be detected and then ignored in do_notify_parent(). Users
of clone3() will now get a proper error right when they pass an
invalid exit signal. Note, that this is not a change in user-visible
behavior since no kernel with clone3() has been released yet"
