commit a019abd802 upstream.
Since commit 2796d0c648 ("bridge: Automatically manage
port promiscuous mode.")
bridges with `vlan_filtering 1` and only 1 auto-port don't
set IFF_PROMISC for unicast-filtering-capable ports.
Normally on port changes `br_manage_promisc` is called to
update the promisc flags and unicast filters if necessary,
but it cannot distinguish between *new* ports and ones
losing their promisc flag, and new ports end up not
receiving the MAC address list.
Fix this by calling `br_fdb_sync_static` in `br_add_if`
after the port promisc flags are updated and the unicast
filter was supposed to have been filled.
Fixes: 2796d0c648 ("bridge: Automatically manage port promiscuous mode.")

The commit d38a2b7a9c ("mm: memcg/slab: fix memory leak at non-root
kmem_cache destroy") introduced a problem: If one thread destroy a
kmem_cache A and another thread concurrently create a kmem_cache B,
which is mergeable with A and has same size with A, the B may fail to
create due to the duplicate sysfs node.
The scenario in detail:
1) Thread 1 uses kmem_cache_destroy() to destroy kmem_cache A which is
mergeable, it decreases A's refcount and if refcount is 0, then call
memcg_set_kmem_cache_dying() which set A->memcg_params.dying = true,
then unlock the slab_mutex and call flush_memcg_workqueue(), it may cost
a while.
Note: now the sysfs node(like '/kernel/slab/:0000248') of A is still
present, it will be deleted in shutdown_cache() which will be called
after flush_memcg_workqueue() is done and lock the slab_mutex again.
2) Now if thread 2 is coming, it use kmem_cache_create() to create B, which
is mergeable with A(their size is same), it gain the lock of slab_mutex,
then call __kmem_cache_alias() trying to find a mergeable node, because
of the below added code in commit d38a2b7a9c ("mm: memcg/slab: fix
memory leak at non-root kmem_cache destroy"), B is not mergeable with
A whose memcg_params.dying is true.
int slab_unmergeable(struct kmem_cache *s)
if (s->refcount < 0)
return 1;
/*
* Skip the dying kmem_cache.
*/
if (s->memcg_params.dying)
return 1;
return 0;
}
So B has to create its own sysfs node by calling:
create_cache->
__kmem_cache_create->
sysfs_slab_add->
kobject_init_and_add
Because B is mergeable itself, its filename of sysfs node is based on its size,
like '/kernel/slab/:0000248', which is duplicate with A, and the sysfs
node of A is still present now, so kobject_init_and_add() will return
fail and result in kmem_cache_create() fail.
Concurrently modprobe and rmmod the two modules below can reproduce the issue
quickly: nf_conntrack_expect, se_sess_cache. See call trace in the end.
LTS versions of v4.19.y and v5.4.y have this problem, whereas linux versions after
v5.9 do not have this problem because the patchset: ("The new cgroup slab memory
controller") almost refactored memcg slab.
A potential solution(this patch belongs): Just let the dying kmem_cache be mergeable,
the slab_mutex lock can prevent the race between alias kmem_cache creating thread
and root kmem_cache destroying thread. In the destroying thread, after
flush_memcg_workqueue() is done, judge the refcount again, if someone
reference it again during un-lock time, we don't need to destroy the kmem_cache
completely, we can reuse it.
Another potential solution: revert the commit d38a2b7a9c ("mm: memcg/slab:
fix memory leak at non-root kmem_cache destroy"), compare to the fail of
kmem_cache_create, the memory leak in special scenario seems less harmful.

Move the turris-mox-rwtm firmware node from Turris MOX' device tree into
the generic armada-37xx.dtsi file and use the generic compatible string
'marvell,armada-3700-rwtm-firmware' instead of the current one.
Turris MOX DTS file contains also old compatible string for backward
compatibility.
The Turris MOX rWTM firmware can be used on any Armada 37xx device,
giving them access to the rWTM hardware random number generator, which
is otherwise unavailable.
This change allows Linux to load the turris-mox-rwtm.ko module on these
boards.
Tested on ESPRESSObin v5 with both default Marvell WTMI firmware and
CZ.NIC's firmware. With default WTMI firmware the turris-mox-rwtm fails
to probe, while with CZ.NIC's firmware it registers the HW random number
generator.

The existing CALL_ON_STACK() macro allows for subtle bugs:
- There is no type checking of the function that is being called. That
is: missing or too many arguments do not cause any compile error or
warning. The same is true if the return type of the called function
changes. This can lead to quite random bugs.
- Sign and zero extension of arguments is missing. Given that the s390
C ABI requires that the caller of a function performs proper sign
and zero extension this can also lead to subtle bugs.
- If arguments to the CALL_ON_STACK() macros contain functions calls
register corruption can happen due to register asm constructs being
used.
Therefore introduce a new call_on_stack() macro which is supposed to
fix all these problems.

Introduce a generic sas_slave_alloc() handler which will return -ENXIO for
SATA devices if the requested LUN number is larger than 0 and make libsas

The shifting of the u8 integer returned fom ahc_inb(ahc, port+3) by 24 bits

the upper 32 bits of the u64 end up as also being set because of the
sign-extension. Fix this by casting the u8 values to a u64 before the 24

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

To avoid unnecessary recompilations, mkcompile_h does not regenerate
compile.h if just the timestamp changed.
Though, if KBUILD_BUILD_TIMESTAMP is set, an explicit timestamp for the
build was requested, in which case we should not ignore it.
If a user follows the documentation for reproducible builds [1] and
defines KBUILD_BUILD_TIMESTAMP as the git commit timestamp, a clean
build will have the correct timestamp. A subsequent cherry-pick (or
amend) changes the commit timestamp and if an incremental build is done
with a different KBUILD_BUILD_TIMESTAMP now, that new value is not taken
into consideration. But it should for reproducibility.
Hence, whenever KBUILD_BUILD_TIMESTAMP is explicitly set, do not ignore
UTS_VERSION when making a decision about whether the regenerated version
of compile.h should be moved into place.

This fixes multiple issues with the current non-existent PCIe clock setup:
The controller can run at up to 250MHz, so use a parent that provides this
clock.
The PHY needs an exact 100MHz reference clock to function if the PCIe
refclock is not fed in via the refclock pads. While this mode is not
supported (yet) in the driver it doesn't hurt to make sure we are
providing a clock with the right rate.
The AUX clock is specified to have a maximum clock rate of 10MHz. So
the current setup, which drives it straight from the 25MHz oscillator is
actually overclocking the AUX input.

[ Upstream commit 174a1dcc96 ]
When building with 'make -s', no output to stdout should be printed.
As Arnd Bergmann reported [1], mkimage shows the detailed information
of the generated images.
I think this should be suppressed by the 'cmd' macro instead of by
individual scripts.
Insert 'exec >/dev/null;' in order to redirect stdout to /dev/null for
silent builds.
[Note about this implementation]
'exec >/dev/null;' may look somewhat tricky, but this has a reason.
Appending '>/dev/null' at the end of command line is a common way for
redirection, so I first tried this:
cmd = @set -e; $(echo-cmd) $(cmd_$(1)) >/dev/null
... but it would not work if $(cmd_$(1)) itself contains a redirection.
For example, cmd_wrap in scripts/Makefile.asm-generic redirects the
output from the 'echo' command into the target file.
It would be expanded into:
echo "#include <asm-generic/$*.h>" > $@ >/dev/null
Then, the target file gets empty because the string will go to /dev/null
instead of $@.
Next, I tried this:
cmd = @set -e; $(echo-cmd) { $(cmd_$(1)); } >/dev/null
The form above would be expanded into:
{ echo "#include <asm-generic/$*.h>" > $@; } >/dev/null
This works as expected. However, it would be a syntax error if
$(cmd_$(1)) is empty.
When CONFIG_TRIM_UNUSED_KSYMS is disabled, $(call cmd,gen_ksymdeps) in
scripts/Makefile.build would be expanded into:
set -e; { ; } >/dev/null
..., which causes an syntax error.
I also tried this:
cmd = @set -e; $(echo-cmd) ( $(cmd_$(1)) ) >/dev/null
... but this causes a syntax error for the same reason.
So, finally I adopted:
cmd = @set -e; $(echo-cmd) exec >/dev/null; $(cmd_$(1))
