Commit 70b62c25665f636c ("LoadPin: Initialize as ordered LSM") removed
CONFIG_DEFAULT_SECURITY_{SELINUX,SMACK,TOMOYO,APPARMOR,DAC} from
security/Kconfig and changed CONFIG_LSM to provide a fixed ordering as a
default value. That commit expected that existing users (upgrading from
Linux 5.0 and earlier) will edit CONFIG_LSM value in accordance with
their CONFIG_DEFAULT_SECURITY_* choice in their old kernel configs. But
since users might forget to edit CONFIG_LSM value, this patch revives
the choice (only for providing the default value for CONFIG_LSM) in order
to make sure that CONFIG_LSM reflects CONFIG_DEFAULT_SECURITY_* from their
old kernel configs.
Note that since TOMOYO can be fully stacked against the other legacy
major LSMs, when it is selected, it explicitly disables the other LSMs
to avoid them also initializing since TOMOYO does not expect this
currently.

The marshalling of AFS.StoreData, AFS.StoreData64 and YFS.StoreData64 calls
generated by ->setattr() ops for the purpose of expanding a file is
incorrect due to older documentation incorrectly describing the way the RPC
'FileLength' parameter is meant to work.
The older documentation says that this is the length the file is meant to
end up at the end of the operation; however, it was never implemented this
way in any of the servers, but rather the file is truncated down to this
before the write operation is effected, and never expanded to it (and,
indeed, it was renamed to 'TruncPos' in 2014).
Fix this by setting the position parameter to the new file length and doing
a zero-lengh write there.
The bug causes Xwayland to SIGBUS due to unexpected non-expansion of a file
it then mmaps. This can be tested by giving the following test program a
filename in an AFS directory:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/mman.h>
int main(int argc, char *argv[])
{
char *p;
int fd;
if (argc != 2) {
fprintf(stderr,
"Format: test-trunc-mmap <file>\n");
exit(2);
}
fd = open(argv[1], O_RDWR | O_CREAT | O_TRUNC);
if (fd < 0) {
perror(argv[1]);
exit(1);
}
if (ftruncate(fd, 0x140008) == -1) {
perror("ftruncate");
exit(1);
}
p = mmap(NULL, 4096, PROT_READ | PROT_WRITE,
MAP_SHARED, fd, 0);
if (p == MAP_FAILED) {
perror("mmap");
exit(1);
}
p[0] = 'a';
if (munmap(p, 4096) < 0) {
perror("munmap");
exit(1);
}
if (close(fd) < 0) {
perror("close");
exit(1);
}
exit(0);
}

Function __hw_perf_event_init() used a CPU variable without

The variable is now accessed in proper context. Use

preemption during access.
As the hardware authorization settings apply to all CPUs, it
does not matter which CPU is used to check the authorization setting.
Remove the event->count assignment. It is not needed as function
perf_event_alloc() allocates memory for the event with kzalloc() and
thus count is already set to zero.

It was caused by the netns freed without deleting the discoverer timer,
while later on the netns would be accessed in the timer handler.
The timer should have been deleted by tipc_net_stop() when cleaning up a
netns. However, tipc has been able to enable a bearer and start d->timer
without the local node_addr set since Commit 52dfae5c85a4 ("tipc: obtain
node identity from interface by default"), which caused the timer not to
be deleted in tipc_net_stop() then.
So fix it in tipc_net_stop() by changing to check local node_id instead
of local node_addr, as Jon suggested.
While at it, remove the calling of tipc_nametbl_withdraw() there, since
tipc_nametbl_stop() will take of the nametbl's freeing after.

This patch implements accessors for the QCA8337 MDIO access
through the MDIO_MASTER register, which makes it possible to
access the PHYs on slave-bus through the switch. In cases
where the switch ports are already mapped via external
"phy-phandles", the internal mdio-bus is disabled in order to
prevent a duplicated discovery and enumeration of the same
PHYs. Don't use mixed external and internal mdio-bus
configurations, as this is not supported by the hardware.

This belated patch implements Andrew Lunn's request of
"remove the phy_read() and phy_write() functions."
<https://lore.kernel.org/patchwork/comment/902734/>
While seemingly harmless, this causes the switch's user
port PHYs to get registered twice. This is because the
DSA subsystem will create a slave mdio-bus not knowing
that the qca8k_phy_(read|write) accessors operate on
the external mdio-bus. So the same "bus" gets effectively
duplicated.

in one place so that other code didn't have to do it.
The track_data_destroy() added later ignored that and also destroyed
the track_data var_ref, causing a double-free error flagged by KASAN.

So far we effectively clear the BMCR register. Some PHY's can deal
with this (e.g. because they reset BMCR to a default as part of a
soft-reset) whilst on others this causes issues because e.g. the
autoneg bit is cleared. Marvell is an example, see also thread [0].
So let's be a little bit more gentle and leave all bits we're not
interested in as-is. This change is needed for PHY drivers to
properly deal with the original patch.

This reverts commit 1aec4211204d9463d1fd209eb50453de16254599.
Steven Rostedt reports that it causes a hang at bootup and bisected it
to this commit.
The troigger is apparently a module alias for "parport_lowlevel" that
points to "parport_pc", which causes a hang with
modprobe -q -- parport_lowlevel
blocking forever with a backtrace like this:
wait_for_completion_killable+0x1c/0x28

do_init_module+0x50/0x1d4
load_module+0x1c2e/0x21b3
sys_init_module+0xef/0x117
Supid says:
"Due to the new device model daisy driver will now try to find the
parallel ports while trying to register its driver so that it can bind
with them. Now, since daisy driver is loaded while parport bus is
initialising the list of parport is still empty and it tries to load
the lowlevel driver, which has an alias set to parport_pc, now causes
a deadlock"
But I don't think the daisy driver should be loaded by the parport
initialization in the first place, so let's revert the whole change.
If the daisy driver can just initialize separately on its own (like a
driver should), instead of hooking into the parport init sequence
directly, this issue probably would go away.

The SPI DT bindings are for historical reasons a pitfall,
the ability to flag a GPIO line as active high/low with
the second cell flags was introduced later so the SPI
subsystem will only accept the bool flag spi-cs-high
to indicate that the line is active high.
It worked by mistake, but the mistake was corrected
in another commit.
The comment in the DTS file was also misleading: this
CS is indeed active high.

Andreas reported that he was seeing the tdbtorture test fail in some
cases with -EDEADLCK when it wasn't before. Some debugging showed that
deadlock detection was sometimes discovering the caller's lock request
itself in a dependency chain.
While we remove the request from the blocked_lock_hash prior to
reattempting to acquire it, any locks that are blocked on that request
will still be present in the hash and will still have their fl_blocker
pointer set to the current request.
This causes posix_locks_deadlock to find a deadlock dependency chain
when it shouldn't, as a lock request cannot block itself.
We are going to end up waking all of those blocked locks anyway when we
go to reinsert the request back into the blocked_lock_hash, so just do
it prior to checking for deadlocks. This ensures that any lock blocked
on the current request will no longer be part of any blocked request
chain.

Even though libbpf's versioning script for the linker (libbpf.map)
is pointing to 0.0.2, the BPF_EXTRAVERSION in the Makefile has
not been updated along with it and is therefore still on 0.0.1.
While fixing up, I also noticed that the generated shared object
versioning information is missing, typical convention is to have
a linker name (libbpf.so), soname (libbpf.so.0) and real name
(libbpf.so.0.0.2) for library management. This is based upon the
LIBBPF_VERSION as well.
The build will then produce the following bpf libraries:
# ll libbpf*
libbpf.a
libbpf.so -> libbpf.so.0.0.2
libbpf.so.0 -> libbpf.so.0.0.2
libbpf.so.0.0.2
# readelf -d libbpf.so.0.0.2 | grep SONAME
0x000000000000000e (SONAME) Library soname: [libbpf.so.0]
