vdpa/mlx5: Fix suspend/resume index restoration
When we suspend the VM, the VDPA interface will be reset. When the VM is
resumed again, clear_virtqueues() will clear the available and used
indices resulting in hardware virqtqueue objects becoming out of sync.
We can avoid this function alltogether since qemu will clear them if
required, e.g. when the VM went through a reboot.
Moreover, since the hw available and used indices should always be
identical on query and should be restored to the same value same value
for virtqueues that complete in order, we set the single value provided
by set_vq_state(). In get_vq_state() we return the value of hardware
used index.

the file descriptors table. As a result, max_fd could exceed the
current fdtable maximum causing us to set excessive bits.
As a concrete example, let's say the user requested everything from fd
4 to ~0UL to be closed and their current fdtable size is 256 with
their highest open fd being 4. With CLOSE_RANGE_UNSHARE the caller
will end up with a new fdtable which has room for 64 file descriptors
since that is the lowest fdtable size we accept. But now max_fd will
still point to 255 and needs to be adjusted. Fix this by retrieving
the correct maximum fd value in __range_cloexec().
I've carried this fix for a little while but since there was no
linux-next release over easter I waited until now.
With this change close_range() can be further simplified but imho we
are in no hurry to do that and so I'll defer this for the 5.13 merge
window"

Pull umount fix from Al Viro:
"Brown paperbag time: dumb braino in the series that went into 5.7
broke the 'don't step into ->d_weak_revalidate() when umount(2) looks
the victim up' behaviour.
Spotted only now - saw
if (!err && unlikely(nd->flags & LOOKUP_MOUNTPOINT)) {
err = handle_lookup_down(nd);
nd->flags &= ~LOOKUP_JUMPED; // no d_weak_revalidate(), please...
}
and went "why do we clear that flag here - nothing below that point is
going to check it anyway" / "wait a minute, what is it doing *after*
complete_walk() (which is where we check that flag and call
->d_weak_revalidate())" / "how could that possibly _not_ break?",
followed by reproducing the breakage and verifying that the obvious
fix of that braino does, indeed, fix it.
The reproducer is (assuming that $DIR exists and is exported r/w to
localhost)
mkdir $DIR/a
mkdir /tmp/foo
mount --bind /tmp/foo /tmp/foo
mkdir /tmp/foo/a
mkdir /tmp/foo/b
mount -t nfs4 localhost:$DIR/a /tmp/foo/a
mount -t nfs4 localhost:$DIR /tmp/foo/b
rmdir /tmp/foo/b/a
umount /tmp/foo/b
umount /tmp/foo/a
umount -l /tmp/foo # will get everything under /tmp/foo, no matter what
Correct behaviour is successful umount; broken kernels (5.7-rc1 and
later) get
umount.nfs4: /tmp/foo/a: Stale file handle
Note that bind mount is there to be able to recover - on broken
kernels we'd get stuck with impossible-to-umount filesystem if not for
that.
FWIW, that braino had been posted for review back then, at least
twice. Unfortunately, the call of complete_walk() was outside of diff
context, so the bogosity hadn't been immediately obvious from the
patch alone ;-/"

KVM: x86/mmu: preserve pending TLB flush across calls to kvm_tdp_mmu_zap_sp
Right now, if a call to kvm_tdp_mmu_zap_sp returns false, the caller
will skip the TLB flush, which is wrong. There are two ways to fix
it:
- since kvm_tdp_mmu_zap_sp will not yield and therefore will not flush
the TLB itself, we could change the call to kvm_tdp_mmu_zap_sp to
use "flush |= ..."
- or we can chain the flush argument through kvm_tdp_mmu_zap_sp down
to __kvm_tdp_mmu_zap_gfn_range. Note that kvm_tdp_mmu_zap_sp will
neither yield nor flush, so flush would never go from true to
false.
This patch does the former to simplify application to stable kernels,
and to make it further clearer that kvm_tdp_mmu_zap_sp will not flush.

selinux: fix race between old and new sidtab
Since commit
1b8b31a2e612 ("selinux: convert policy read-write lock to
RCU"), there is a small window during policy load where the new policy
pointer has already been installed, but some threads may still be
holding the old policy pointer in their read-side RCU critical sections.
This means that there may be conflicting attempts to add a new SID entry
to both tables via sidtab_context_to_sid().
See also (and the rest of the thread):
https://lore.kernel.org/selinux/CAFqZXNvfux46_f8gnvVvRYMKoes24nwm2n3sPbMjrB8vKTW00g@mail.gmail.com/
Fix this by installing the new policy pointer under the old sidtab's
spinlock along with marking the old sidtab as "frozen". Then, if an
attempt to add new entry to a "frozen" sidtab is detected, make
sidtab_context_to_sid() return -ESTALE to indicate that a new policy
has been installed and that the caller will have to abort the policy
transaction and try again after re-taking the policy pointer (which is
guaranteed to be a newer policy). This requires adding a retry-on-ESTALE
logic to all callers of sidtab_context_to_sid(), but fortunately these
are easy to determine and aren't that many.
This seems to be the simplest solution for this problem, even if it
looks somewhat ugly. Note that other places in the kernel (e.g.
do_mknodat() in fs/namei.c) use similar stale-retry patterns, so I think
it's reasonable.

of: properly check for error returned by fdt_get_name()
fdt_get_name() returns error values via a parameter pointer
instead of in function return. Fix check for this error value
in populate_node() and callers of populate_node().
Chasing up the caller tree showed callers of various functions
failing to initialize the value of pointer parameters that
can return error values. Initialize those values to NULL.
The bug was introduced by
commit
e6a6928c3ea1 ("of/fdt: Convert FDT functions to use libfdt")
but this patch can not be backported directly to that commit
because the relevant code has further been restructured by
commit

ACPI: processor: Fix build when CONFIG_ACPI_PROCESSOR=m
Commit
8cdddd182bd7 ("ACPI: processor: Fix CPU0 wakeup in
acpi_idle_play_dead()") tried to fix CPU0 hotplug breakage by copying
wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead()
into acpi_idle_play_dead(). The problem is that these functions are not
exported to modules so when CONFIG_ACPI_PROCESSOR=m build fails.
The issue could've been fixed by exporting both wakeup_cpu0()/start_cpu0()
(the later from assembly) but it seems putting the whole pattern into a
new function and exporting it instead is better.

Initialize them in set_nameidata() and make sure that terminate_walk() clears them

accesses them outside of path_init()/terminate_walk() segments", which is asking

With that change we would have nd->path.{mnt,dentry}

firewire: nosy: Fix a use-after-free bug in nosy_ioctl()
For each device, the nosy driver allocates a pcilynx structure.
A use-after-free might happen in the following scenario:
1. Open nosy device for the first time and call ioctl with command
NOSY_IOC_START, then a new client A will be malloced and added to
doubly linked list.
2. Open nosy device for the second time and call ioctl with command
NOSY_IOC_START, then a new client B will be malloced and added to
doubly linked list.
3. Call ioctl with command NOSY_IOC_START for client A, then client A
will be readded to the doubly linked list. Now the doubly linked
list is messed up.
4. Close the first nosy device and nosy_release will be called. In
nosy_release, client A will be unlinked and freed.
5. Close the second nosy device, and client A will be referenced,
resulting in UAF.
The root cause of this bug is that the element in the doubly linked list
is reentered into the list.
Fix this bug by adding a check before inserting a client. If a client
is already in the linked list, don't insert it.
The following KASAN report reveals it:

workqueue/watchdog: Make unbound workqueues aware of touch_softlockup_watchdog()
84;0;0c84;0;0c
There are two workqueue-specific watchdog timestamps:
+ @wq_watchdog_touched_cpu (per-CPU) updated by
touch_softlockup_watchdog()
+ @wq_watchdog_touched (global) updated by
touch_all_softlockup_watchdogs()
watchdog_timer_fn() checks only the global @wq_watchdog_touched for
unbound workqueues. As a result, unbound workqueues are not aware
of touch_softlockup_watchdog(). The watchdog might report a stall
even when the unbound workqueues are blocked by a known slow code.
Solution:
touch_softlockup_watchdog() must touch also the global @wq_watchdog_touched
timestamp.
The global timestamp can no longer be used for bound workqueues because
it is now updated from all CPUs. Instead, bound workqueues have to check
only @wq_watchdog_touched_cpu and these timestamps have to be updated for
all CPUs in touch_all_softlockup_watchdogs().
Beware:
The change might cause the opposite problem. An unbound workqueue
might get blocked on CPU A because of a real softlockup. The workqueue
watchdog would miss it when the timestamp got touched on CPU B.
It is acceptable because softlockups are detected by softlockup
watchdog. The workqueue watchdog is there to detect stalls where
a work never finishes, for example, because of dependencies of works
queued into the same workqueue.
V3:
- Modify the commit message clearly according to Petr's suggestion.

ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin
Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.
Without this the pin is by default in LED[2] mode, and the Marvell PHY
driver configures LED[2] into "On - Link, Blink - Activity" mode.
This fixes the issue where the pca9538 GPIO/interrupt controller (which
can't mask interrupts in HW) received too many interrupts and after a
time started ignoring the interrupt with error message:
IRQ 71: nobody cared
There is a work in progress to have the Marvell PHY driver support
parsing PHY LED nodes from OF and registering the LEDs as Linux LED
class devices. Once this is done the PHY driver can also automatically
set the pin into INTn mode if it does not find LED[2] in OF.
Until then, though, we fix this via `marvell,reg-init` DT property.

The big top of the file comment talk about grand plans that never
happened, so remove them to not confuse the readers. Also mark the
devname and volname fields as ignored as they were never used by the

selinux: fix cond_list corruption when changing booleans
Currently, duplicate_policydb_cond_list() first copies the whole
conditional avtab and then tries to link to the correct entries in
cond_dup_av_list() using avtab_search(). However, since the conditional
avtab may contain multiple entries with the same key, this approach
often fails to find the right entry, potentially leading to wrong rules
being activated/deactivated when booleans are changed.
To fix this, instead start with an empty conditional avtab and add the
individual entries one-by-one while building the new av_lists. This
approach leads to the correct result, since each entry is present in the
av_lists exactly once.
The issue can be reproduced with Fedora policy as follows:
# sesearch -s ftpd_t -t public_content_rw_t -c dir -p create -A
allow ftpd_t non_security_file_type:dir { add_name create getattr ioctl link lock open read remove_name rename reparent rmdir search setattr unlink watch watch_reads write }; [ ftpd_full_access ]:True
allow ftpd_t public_content_rw_t:dir { add_name create link remove_name rename reparent rmdir setattr unlink watch watch_reads write }; [ ftpd_anon_write ]:True
# setsebool ftpd_anon_write=off ftpd_connect_all_unreserved=off ftpd_connect_db=off ftpd_full_access=off
On fixed kernels, the sesearch output is the same after the setsebool
command:
# sesearch -s ftpd_t -t public_content_rw_t -c dir -p create -A
allow ftpd_t non_security_file_type:dir { add_name create getattr ioctl link lock open read remove_name rename reparent rmdir search setattr unlink watch watch_reads write }; [ ftpd_full_access ]:True
allow ftpd_t public_content_rw_t:dir { add_name create link remove_name rename reparent rmdir setattr unlink watch watch_reads write }; [ ftpd_anon_write ]:True
While on the broken kernels, it will be different:
# sesearch -s ftpd_t -t public_content_rw_t -c dir -p create -A
allow ftpd_t non_security_file_type:dir { add_name create getattr ioctl link lock open read remove_name rename reparent rmdir search setattr unlink watch watch_reads write }; [ ftpd_full_access ]:True
allow ftpd_t non_security_file_type:dir { add_name create getattr ioctl link lock open read remove_name rename reparent rmdir search setattr unlink watch watch_reads write }; [ ftpd_full_access ]:True
allow ftpd_t non_security_file_type:dir { add_name create getattr ioctl link lock open read remove_name rename reparent rmdir search setattr unlink watch watch_reads write }; [ ftpd_full_access ]:True
While there, also simplify the computation of nslots. This changes the
nslots values for nrules 2 or 3 to just two slots instead of 4, which
makes the sequence more consistent.
