[ Upstream commit 293e38ff4e ]
SGMII_CTRL register, which specifies the active interface, was not
properly restored when resuming from suspend. This led to incorrect
interface selection after resume particularly in scenarios involving
the FPGA.
To fix this:
- Move the SGMII_CTRL setup out of the probe function.
- Initialize the register in the hardware initialization helper function,
which is called during both device initialization and resume.
This ensures the interface configuration is consistently restored after
suspend/resume cycles.

[ Upstream commit 47653e4243 ]
While the MDIO address of the internal PHY on Allwinner sun8i chips is
generally 1, of_mdio_parse_addr is used to cleanly parse the address
from the device-tree instead of hardcoding it.
A commit reworking the code ditched the parsed value and hardcoded the
value 1 instead, which didn't really break anything but is more fragile
and not future-proof.
Restore the initial behavior using the parsed address returned from the
helper.

[ Upstream commit 22ee670a8a ]
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
To convert all those qcom pinctrl drivers, make msm_pinctrl_remove()
return void (instead of zero) and use .remove_new in all drivers.

If an aggregate has the following conditions:
- The SRIOV LAG DDP package has been enabled
- The bond is in 802.3ad LACP mode
- The bond is disqualified from supporting SRIOV VF LAG
- Both interfaces were added simultaneously to the bond (same command)
Then there is a chance that the two interfaces will be assigned different
LACP Aggregator ID's. This will cause a failure of the LACP control over
the bond.
To fix this, we can detect if the primary interface for the bond (as
defined by the driver) is not in switchdev mode, and exit the setup flow
if so.
Reproduction steps:
%> ip link add bond0 type bond mode 802.3ad miimon 100
%> ip link set bond0 up
%> ifenslave bond0 eth0 eth1
%> cat /proc/net/bonding/bond0 | grep Agg

The ice_vc_repr_add_mac() function indicates that it does not store the MAC
address filters in the firmware. However, it still increments vf->num_mac.
This is incorrect, as vf->num_mac should represent the number of MAC
filters currently programmed to firmware.
Indeed, we only perform this increment if the requested filter is a unicast
address that doesn't match the existing vf->hw_lan_addr. In addition,
ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This
results in the counter becoming out of sync with the actual count.
As it turns out, vf->num_mac is currently only used in legacy made without
port representors. The single place where the value is checked is for
enforcing a filter limit on untrusted VFs.
Upcoming patches to support VF Live Migration will use this value when
determining the size of the TLV for MAC address filters. Fix the
representor mode function to stop incrementing the counter incorrectly.

[ Upstream commit 91b6dbced0 ]
When netfilter defrag hooks are loaded (due to the presence of conntrack
rules, for example), fragmented packets entering the bridge will be
defragged by the bridge's pre-routing hook (br_nf_pre_routing() ->
ipv4_conntrack_defrag()).
Later on, in the bridge's post-routing hook, the defragged packet will
be fragmented again. If the size of the largest fragment is larger than
what the kernel has determined as the destination MTU (using
ip_skb_dst_mtu()), the defragged packet will be dropped.
Before commit ac6627a28d ("net: ipv4: Consolidate ipv4_mtu and
ip_dst_mtu_maybe_forward"), ip_skb_dst_mtu() would return dst_mtu() as
the destination MTU. Assuming the dst entry attached to the packet is
the bridge's fake rtable one, this would simply be the bridge's MTU (see
fake_mtu()).
However, after above mentioned commit, ip_skb_dst_mtu() ends up
returning the route's MTU stored in the dst entry's metrics. Ideally, in
case the dst entry is the bridge's fake rtable one, this should be the
bridge's MTU as the bridge takes care of updating this metric when its
MTU changes (see br_change_mtu()).
Unfortunately, the last operation is a no-op given the metrics attached
to the fake rtable entry are marked as read-only. Therefore,
ip_skb_dst_mtu() ends up returning 1500 (the initial MTU value) and
defragged packets are dropped during fragmentation when dealing with
large fragments and high MTU (e.g., 9k).
Fix by moving the fake rtable entry's metrics to be per-bridge (in a
similar fashion to the fake rtable entry itself) and marking them as
writable, thereby allowing MTU changes to be reflected.

Prior to this patch, the mark is sanitized (applying the state's mask to
the state's value) only on inserts when checking if a conflicting XFRM
state or policy exists.
We discovered in Cilium that this same sanitization does not occur
in the hot-path __xfrm_state_lookup. In the hot-path, the sk_buff's mark
is simply compared to the state's value:
if ((mark & x->mark.m) != x->mark.v)
continue;
Therefore, users can define unsanitized marks (ex. 0xf42/0xf00) which will
never match any packet.
This commit updates __xfrm_state_insert and xfrm_policy_insert to store
the sanitized marks, thus removing this footgun.
This has the side effect of changing the ip output, as the
returned mark will have the mask applied to it when printed.

Not intuitive, but vm_area_dup() located in kernel/fork.c is not only used
for duplicating VMAs during fork(), but also for duplicating VMAs when
splitting VMAs or when mremap()'ing them.
VM_PFNMAP mappings can at least get ordinarily mremap()'ed (no change in
size) and apparently also shrunk during mremap(), which implies
duplicating the VMA in __split_vma() first.
In case of ordinary mremap() (no change in size), we first duplicate the
VMA in copy_vma_and_data()->copy_vma() to then call untrack_pfn_clear() on
the old VMA: we effectively move the VM_PAT reservation. So the
untrack_pfn_clear() call on the new VMA duplicating is wrong in that
context.
Splitting of VMAs seems problematic, because we don't duplicate/adjust the
reservation when splitting the VMA. Instead, in memtype_erase() -- called
during zapping/munmap -- we shrink a reservation in case only the end
address matches: Assume we split a VMA into A and B, both would share a
reservation until B is unmapped.
So when unmapping B, the reservation would be updated to cover only A.
When unmapping A, we would properly remove the now-shrunk reservation.
That scenario describes the mremap() shrinking (old_size > new_size),
where we split + unmap B, and the untrack_pfn_clear() on the new VMA when
is wrong.
What if we manage to split a VM_PFNMAP VMA into A and B and unmap A first?
It would be broken because we would never free the reservation. Likely,
there are ways to trigger such a VMA split outside of mremap().
Affecting other VMA duplication was not intended, vm_area_dup() being used
outside of kernel/fork.c was an oversight. So let's fix that for; how to
handle VMA splits better should be investigated separately.
With a simple reproducer that uses mprotect() to split such a VMA I can

The current scheme for caching the encap socket can lead to reference
leaks when we try to delete the netns.
The reference chain is: xfrm_state -> enacp_sk -> netns
Since the encap socket is a userspace socket, it holds a reference on
the netns. If we delete the espintcp state (through flush or
individual delete) before removing the netns, the reference on the
socket is dropped and the netns is correctly deleted. Otherwise, the
netns may not be reachable anymore (if all processes within the ns
have terminated), so we cannot delete the xfrm state to drop its
reference on the socket.
This patch results in a small (~2% in my tests) performance
regression.
A GC-type mechanism could be added for the socket cache, to clear
references if the state hasn't been used "recently", but it's a lot
more complex than just not caching the socket.

Function CIFSSMBSetPathInfo() is not supported by non-NT servers and
returns error. Fallback code via open filehandle and CIFSSMBSetFileInfo()
does not work neither because CIFS_open() works also only on NT server.
Therefore currently the whole smb_set_file_info() function as a SMB1
callback for the ->set_file_info() does not work with older non-NT SMB
servers, like Win9x and others.
This change implements fallback code in smb_set_file_info() which will
works with any server and allows to change time values and also to set or
clear read-only attributes.
To make existing fallback code via CIFSSMBSetFileInfo() working with also
non-NT servers, it is needed to change open function from CIFS_open()
(which is NT specific) to cifs_open_file() which works with any server
(this is just a open wrapper function which choose the correct open
function supported by the server).
CIFSSMBSetFileInfo() is working also on non-NT servers, but zero time
values are not treated specially. So first it is needed to fill all time
values if some of them are missing, via cifs_query_path_info() call.
There is another issue, opening file in write-mode (needed for changing
attributes) is not possible when the file has read-only attribute set.
The only option how to clear read-only attribute is via SMB_COM_SETATTR
command. And opening directory is not possible neither and here the
SMB_COM_SETATTR command is the only option how to change attributes.
And CIFSSMBSetFileInfo() does not honor setting read-only attribute, so
for setting is also needed to use SMB_COM_SETATTR command.
Existing code in cifs_query_path_info() is already using SMB_COM_GETATTR as
a fallback code path (function SMBQueryInformation()), so introduce a new
function SMBSetInformation which will implement SMB_COM_SETATTR command.
My testing showed that Windows XP SMB1 client is also using SMB_COM_SETATTR
command for setting or clearing read-only attribute against non-NT server.
So this can prove that this is the correct way how to do it.
With this change it is possible set all 4 time values and all attributes,
including clearing and setting read-only bit on non-NT SMB servers.
Tested against Win98 SMB1 server.
This change fixes "touch" command which was failing when called on existing
file. And fixes also "chmod +w" and "chmod -w" commands which were also
failing (as they are changing read-only attribute).
Note that this change depends on following change
"cifs: Improve cifs_query_path_info() and cifs_query_file_info()"
as it require to query all 4 time attribute values.

[ Upstream commit 1041c117a2 ]
When CAP_NT_SMBS was not negotiated then do not issue CIFSSMBQPathInfo()
and CIFSSMBQFileInfo() commands. CIFSSMBQPathInfo() is not supported by
non-NT Win9x SMB server and CIFSSMBQFileInfo() returns from Win9x SMB
server bogus data in Attributes field (for example lot of files are marked
as reparse points, even Win9x does not support them and read-only bit is
not marked for read-only files). Correct information is returned by
CIFSFindFirst() or SMBQueryInformation() command.
So as a fallback in cifs_query_path_info() function use CIFSFindFirst()
with SMB_FIND_FILE_FULL_DIRECTORY_INFO level which is supported by both NT
and non-NT servers and as a last option use SMBQueryInformation() as it was
before.
And in function cifs_query_file_info() immediately returns -EOPNOTSUPP when
not communicating with NT server. Client then revalidate inode entry by the
cifs_query_path_info() call, which is working fine. So fstat() syscall on
already opened file will receive correct information.
Note that both fallback functions in non-UNICODE mode expands wildcards.
Therefore those fallback functions cannot be used on paths which contain
SMB wildcard characters (* ? " > <).
CIFSFindFirst() returns all 4 time attributes as opposite of
SMBQueryInformation() which returns only one.
With this change it is possible to query all 4 times attributes from Win9x
server and at the same time, client minimize sending of unsupported
commands to server.

syzbot complains about the cached sq head read, and it's totally right.
But we don't need to care, it's just reading fdinfo, and reading the
CQ or SQ tail/head entries are known racy in that they are just a view
into that very instant and may of course be outdated by the time they
are reported.
Annotate both the SQ head and CQ tail read with data_race() to avoid
this syzbot complaint.

[ Upstream commit e56088a137 ]
The public datasheets of the following Amlogic SoCs describe a typical
resistor value for the built-in pull up/down resistor:
- Meson8/8b/8m2: not documented
- GXBB (S905): 60 kOhm
- GXL (S905X): 60 kOhm
- GXM (S912): 60 kOhm
- G12B (S922X): 60 kOhm
- SM1 (S905D3): 60 kOhm
The public G12B and SM1 datasheets additionally state min and max
values:
- min value: 50 kOhm for both, pull-up and pull-down
- max value for the pull-up: 70 kOhm
- max value for the pull-down: 130 kOhm
Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the
debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality
60 kOhm is closer to the actual value than 1 Ohm.

[ Upstream commit 749b5b279e ]
We have a few reports of sc7180-trogdor-pompom devices that have a
panel in them that IDs as STA 0x0004 and has the following raw EDID:
00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00
10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28

00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6
We've been unable to locate a datasheet for this panel and our partner
has not been responsive, but all Starry eDP datasheets that we can
find agree on the same timing (delay_100_500_e200) so it should be
safe to use that here instead of the super conservative timings. We'll
still go a little extra conservative and allow `hpd_absent` of 200
instead of 100 because that won't add any real-world delay in most
cases.
We'll associate the string from the EDID ("116KHD024006") with this
panel. Given that the ID is the suspicious value of 0x0004 it seems
likely that Starry doesn't always update their IDs but the string will
still work to differentiate if we ever need to in the future.

[ Upstream commit c5e3306a42 ]
msm is automagically upgrading normal commits to full modesets, and
that's a big no-no:
- for one this results in full on->off->on transitions on all these
crtc, at least if you're using the usual helpers. Which seems to be
the case, and is breaking uapi
- further even if the ctm change itself would not result in flicker,
this can hide modesets for other reasons. Which again breaks the
uapi

and link to the existing kerneldoc explainers. This has come up in an
