[ Upstream commit e127906b68 ]
Commit eaf4fac478 ("net: stmmac: Do not accept invalid MTU values")
started using the TX FIFO size to verify what counts as a valid MTU
request for the stmmac driver. This is unset for the ipq806x variant.
Looking at older patches for this it seems the RX + TXs buffers can be
up to 8k, so set appropriately.
(I sent this as an RFC patch in June last year, but received no replies.
I've been running with this on my hardware (a MikroTik RB3011) since
then with larger MTUs to support both the internal qca8k switch and
VLANs with no problems. Without the patch it's impossible to set the
larger MTU required to support this.)

commit 34e5b01186 upstream.
As Or Cohen described:
If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock
held and sp->do_auto_asconf is true, then an element is removed
from the auto_asconf_splist without any proper locking.
This can happen in the following functions:
1. In sctp_accept, if sctp_sock_migrate fails.
2. In inet_create or inet6_create, if there is a bpf program
attached to BPF_CGROUP_INET_SOCK_CREATE which denies
creation of the sctp socket.
This patch is to fix it by moving the auto_asconf init out of
sctp_init_sock(), by which inet_create()/inet6_create() won't
need to operate it in sctp_destroy_sock() when calling
sk_common_release().
It also makes more sense to do auto_asconf init while binding the
first addr, as auto_asconf actually requires an ANY addr bind,
see it in sctp_addr_wq_timeout_handler().
This addresses CVE-2021-23133.

[ Upstream commit 926ee00ea2 ]
The intent with this code was to return negative error codes but instead
it returns positives.
The problem is how type promotion works with ternary operations. These
functions return long, "ret" is an int and "copied" is a u32. The
negative error code is first cast to u32 so it becomes a high positive and
then cast to long where it's still a positive.
We could fix this by declaring "ret" as a ssize_t but let's just get rid
of the ternaries instead.

[ Upstream commit 7dd9a40fd6 ]
When the error check in ath9k_hw_read_revisions() was added, it checked for
-EIO which is what ath9k_regread() in the ath9k_htc driver uses. However,
for plain ath9k, the register read function uses ioread32(), which just
returns -1 on error. So if such a read fails, it still gets passed through
and ends up as a weird mac revision in the log output.
Fix this by changing ath9k_regread() to return -1 on error like ioread32()
does, and fix the error check to look for that instead of -EIO.

Mirror commit aeba3731b1 ("powerpc/pci: Fix IO space breakage after
of_pci_range_to_resource() change").
Most MIPS platforms do not define PCI_IOBASE, nor implement
pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0xffff for most MIPS
platforms. of_pci_range_to_resource passes the _start address_ of the IO
range into pci_address_to_pio, which then checks it against
IO_SPACE_LIMIT and fails, because for MIPS platforms that use
pci-legacy (pci-lantiq, pci-rt3883, pci-mt7620), IO ranges start much
higher than 0xffff.
In fact, pci-mt7621 in staging already works around this problem, see
commit 09dd629eea ("staging: mt7621-pci: fix io space and properly set
resource limits")
So just stop using of_pci_range_to_resource, which does not work for
MIPS.

Currently the expression ~nic_conf1 is always true because nic_conf1
is a u16 and according to 6.5.3.3 of the C standard the ~ operator
promotes the u16 to an integer before flipping all the bits. Thus
the top 16 bits of the integer result are all set so the expression
is always true. If the intention was to flip all the bits of nic_conf1
then casting the integer result back to a u16 is a suitabel fix.
Interestingly static analyzers seem to thing a bitwise ! should be
used instead of ~ for this scenario, so I think the original intent
of the expression may need some extra consideration.

The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port
(a u16) left 24 places. There are two subtle issues here, first the
shift gets promoted to an signed int and then sign extended to a u64.
If oct->pcie_port is 0x80 or more then the upper bits get sign extended
to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it
needs to be cast to a u64 for all the bits to not overflow.
It is entirely possible that the u16 port value is never large enough
for this to fail, but it is useful to fix unintended overflows such
as this.
Fix this by casting the port parameter to the macro to a u64 before
the shift.

sure that the LAPB APIs called in these functions are called before
"lapb_unregister" is called by the "ndo_stop" function.
However, these "netif_running" checks are unreliable, because it's
possible that immediately after "netif_running" returns true, "ndo_stop"
is called (which causes "lapb_unregister" to be called).
This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can
reliably check and ensure the netif is running while doing their work.

The patch was tested on the mentioned model only, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected, because the
rate is about 3 times per second, which is far less frequent than once
in 5 ms.

[ Upstream commit de5bc7b425 ]
dev_attr_show() calls _iommu_event_show() via an indirect call but
_iommu_event_show()'s type does not currently match the type of the
show() member in 'struct device_attribute', resulting in a Control Flow
Integrity violation.

$ dmesg | grep "CFI failure"
[ 3526.735140] CFI failure (target: _iommu_event_show...):
Change _iommu_event_show() and 'struct amd_iommu_event_desc' to
'struct device_attribute' so that there is no more CFI violation.

[ Upstream commit 5c08b0f755 ]
If some of the allocations fail between the dev_set_name() and the
device_register() then the name will not be freed. Fix this by
moving dev_set_name() directly in front of the call to device_register().

[ Upstream commit f6b1340dc7 ]
The for-loop iterates with a u8 loop counter i and compares this
with the loop upper limit of num_parents that is an int type.
There is a potential infinite loop if num_parents is larger than
the u8 loop counter. Fix this by making the loop counter the same
type as num_parents. Also make num_parents an unsigned int to
match the return type of the call to clk_hw_get_num_parents.

[ Upstream commit e6471a65fd ]
The function mv_platform_probe() neglects to check the results of the
calls to platform_get_irq() and irq_of_parse_and_map() and blithely
passes them to ata_host_activate() -- while the latter only checks
for IRQ0 (treating it as a polling mode indicattion) and passes the
negative values to devm_request_irq() causing it to fail as it takes
unsigned values for the IRQ #...
Add to mv_platform_probe() the proper IRQ checks to pass the positive IRQ
#s to ata_host_activate(), propagate upstream the negative error codes,
and override the IRQ0 with -EINVAL (as we don't want the polling mode).

[ Upstream commit e379b40cc0 ]
The driver's probe() method is written as if platform_get_irq() returns 0
on error, while actually it returns a negative error code (with all the
other values considered valid IRQs). Rewrite the driver's IRQ checking
code to pass the positive IRQ #s to ata_host_activate(), propagate errors
upstream, and treat IRQ0 as error, returning -EINVAL, as the libata code
treats 0 as an indication that polling should be used anyway...
