Qualcomm driver updates for v6.6
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

In the AMD SEV-SNP guest, AP needs to be started up via sev es

to pass the gpa of sev es save area with AP's vp index and VTL(Virtual
trust level) parameters. Override wakeup_secondary_cpu_64 callback
with hv_snp_boot_ap.

SEV-SNP guests on Hyper-V can run at multiple Virtual Trust
Levels (VTL). During boot, get the VTL at which we're running
using the GET_VP_REGISTERs hypercall, and save the value
for future use. Then during VMBus initialization, set the VTL
with the saved value as required in the VMBus init message.

Adding support to specify pid for uprobe_multi link and the uprobes
are created only for task with given pid value.
Using the consumer.filter filter callback for that, so the task gets
filtered during the uprobe installation.
We still need to check the task during runtime in the uprobe handler,
because the handler could get executed if there's another system
wide consumer on the same uprobe (thanks Oleg for the insight).

Adding new multi uprobe link that allows to attach bpf program
to multiple uprobes.
Uprobes to attach are specified via new link_create uprobe_multi
union:
struct {
__aligned_u64 path;
__aligned_u64 offsets;
__aligned_u64 ref_ctr_offsets;
__u32 cnt;
__u32 flags;
} uprobe_multi;
Uprobes are defined for single binary specified in path and multiple
calling sites specified in offsets array with optional reference
counters specified in ref_ctr_offsets array. All specified arrays
have length of 'cnt'.
The 'flags' supports single bit for now that marks the uprobe as
return probe.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct icc_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

Introduce infrastructure in the driver to support the processing of
unsolicited LS (Link Service) requests. This will involve the utilization
of a new pass-up of unsolicited FC-NVMe request IOCB interface. Unsolicited
requests will be submitted to the NVMe transport layer through
nvme_fc_rcv_ls_req(). Any received LS responses, which are sent using
xmt_ls_rsp(), will be forwarded to the firmware through the existing
Pass-Through IOCB interface, responsible for sending FC-NVMe Link Service
requests and responses.

Move PG_writeback into bottom byte so that it can use PG_waiters in a
later patch. Move PG_head into bottom byte as well to match with where
'order' is moving next. PG_active and PG_workingset move into the second
byte to make room for them.
By putting PG_head in bit 6, we ensure that it is cleared by assigning the
folio order to the bottom byte of the first tail page (since the order
cannot be larger than 63).

Especially the "For PROT_NONE VMAs, the PTEs are not marked
_PAGE_PROTNONE" part is wrong: doing an mprotect(PROT_NONE) will end up
marking all PTEs on x86_64 as _PAGE_PROTNONE, making pte_protnone()
indicate "yes".
So let's improve the comment, so it's easier to grasp which semantics
pte_protnone() actually has.

Eric has pointed out that we still have 3 users of do_each_thread().
Change them to use for_each_process_thread() and kill this helper.
There is a subtle change, after do_each_thread/while_each_thread g == t ==
&init_task, while after for_each_process_thread() they both point to
nowhere, but this doesn't matter.
> Why is for_each_process_thread() better than do_each_thread()?
Say, for_each_process_thread() is rcu safe, do_each_thread() is not.
And certainly
for_each_process_thread(p, t) {
do_something(p, t);
}
looks better than
do_each_thread(p, t) {
do_something(p, t);
} while_each_thread(p, t);
And again, there are only 3 users of this awkward helper left. It should
have been killed years ago and in fact I thought it had already been
killed. It uses while_each_thread() which needs some changes.

Sparse is not happy to see non-static variable without declaration:
lib/vsprintf.c:61:6: warning: symbol 'no_hash_pointers' was not declared.
Should it be static?
Declare respective variable in the sprintf.h. With this, add a comment to
discourage its use if no real need.

Patch series "lib/vsprintf: Rework header inclusions", v3.
Some patches that reduce the mess with the header inclusions related to
vsprintf.c module. Each patch has its own description, and has no
dependencies to each other, except the collisions over modifications of
the same places. Hence the series.
This patch (of 2):
kernel.h is being used as a dump for all kinds of stuff for a long time.
sprintf() and friends are used in many drivers without need of the full
kernel.h dependency train with it.
Here is the attempt on cleaning it up by splitting out sprintf() and
friends.

This sysctl has the very unusual behaviour of not allowing any user (even
CAP_SYS_ADMIN) to reduce the restriction setting, meaning that if you were
to set this sysctl to a more restrictive option in the host pidns you
would need to reboot your machine in order to reset it.
The justification given in [1] is that this is a security feature and thus
it should not be possible to disable. Aside from the fact that we have
plenty of security-related sysctls that can be disabled after being
enabled (fs.protected_symlinks for instance), the protection provided by
the sysctl is to stop users from being able to create a binary and then
execute it. A user with CAP_SYS_ADMIN can trivially do this without
memfd_create(2):
% cat mount-memfd.c
#include <fcntl.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <linux/mount.h>
#define SHELLCODE "#!/bin/echo this file was executed from this totally private tmpfs:"
int main(void)
{
int fsfd = fsopen("tmpfs", FSOPEN_CLOEXEC);
assert(fsfd >= 0);
assert(!fsconfig(fsfd, FSCONFIG_CMD_CREATE, NULL, NULL, 2));
int dfd = fsmount(fsfd, FSMOUNT_CLOEXEC, 0);
assert(dfd >= 0);
int execfd = openat(dfd, "exe", O_CREAT | O_RDWR | O_CLOEXEC, 0782);
assert(execfd >= 0);
assert(write(execfd, SHELLCODE, strlen(SHELLCODE)) == strlen(SHELLCODE));
assert(!close(execfd));
char *execpath = NULL;
char *argv[] = { "bad-exe", NULL }, *envp[] = { NULL };
execfd = openat(dfd, "exe", O_PATH | O_CLOEXEC);
assert(execfd >= 0);
assert(asprintf(&execpath, "/proc/self/fd/%d", execfd) > 0);
assert(!execve(execpath, argv, envp));
}
% ./mount-memfd
this file was executed from this totally private tmpfs: /proc/self/fd/5
%
Given that it is possible for CAP_SYS_ADMIN users to create executable
binaries without memfd_create(2) and without touching the host filesystem
(not to mention the many other things a CAP_SYS_ADMIN process would be
able to do that would be equivalent or worse), it seems strange to cause a
fair amount of headache to admins when there doesn't appear to be an
actual security benefit to blocking this. There appear to be concerns
about confused-deputy-esque attacks[2] but a confused deputy that can
write to arbitrary sysctls is a bigger security issue than executable
memfds.
/* New API */
The primary requirement from the original author appears to be more based
on the need to be able to restrict an entire system in a hierarchical
manner[3], such that child namespaces cannot re-enable executable memfds.
So, implement that behaviour explicitly -- the vm.memfd_noexec scope is
evaluated up the pidns tree to &init_pid_ns and you have the most
restrictive value applied to you. The new lower limit you can set
vm.memfd_noexec is whatever limit applies to your parent.
Note that a pidns will inherit a copy of the parent pidns's effective
vm.memfd_noexec setting at unshare() time. This matches the existing
behaviour, and it also ensures that a pidns will never have its
vm.memfd_noexec setting *lowered* behind its back (but it will be raised
if the parent raises theirs).
/* Backwards Compatibility */
As the previous version of the sysctl didn't allow you to lower the
setting at all, there are no backwards compatibility issues with this
aspect of the change.
However it should be noted that now that the setting is completely
hierarchical. Previously, a cloned pidns would just copy the current
pidns setting, meaning that if the parent's vm.memfd_noexec was changed it
wouldn't propoagate to existing pid namespaces. Now, the restriction
applies recursively. This is a uAPI change, however:
* The sysctl is very new, having been merged in 6.3.
* Several aspects of the sysctl were broken up until this patchset and
the other patchset by Jeff Xu last month.
And thus it seems incredibly unlikely that any real users would run into
this issue. In the worst case, if this causes userspace isues we could
make it so that modifying the setting follows the hierarchical rules but
the restriction checking uses the cached copy.

Given the difficulty of auditing all of userspace to figure out whether
every memfd_create() user has switched to passing MFD_EXEC and
MFD_NOEXEC_SEAL flags, it seems far less distruptive to make it possible
for older programs that don't make use of executable memfds to run under
vm.memfd_noexec=2. Otherwise, a small dependency change can result in
spurious errors. For programs that don't use executable memfds, passing
MFD_NOEXEC_SEAL is functionally a no-op and thus having the same
In addition, every failure under vm.memfd_noexec=2 needs to print to the
kernel log so that userspace can figure out where the error came from.
The concerns about pr_warn_ratelimited() spam that caused the switch to
pr_warn_once()[1,2] do not apply to the vm.memfd_noexec=2 case.
This is a user-visible API change, but as it allows programs to do
something that would be blocked before, and the sysctl itself was broken
and recently released, it seems unlikely this will cause any issues.

these to use pagetable_alloc() and ptdesc_address() instead to help
