The v8 abi is supported by the kernel but the userspace supported

due to a bug in the userspace compiler which was setting an older abi
version for v8 encoding (which is forward compatible except on the
network encoding). However it is possible to detect the network
encoding by checking the policydb network support which the code
does. The end result was that missing the abi flag worked until

[ Upstream commit

Whenever trying to load XDP prog on downed interface, function i40e_xdp
was passing vsi->rx_buf_len field to i40e_xdp_setup() which was equal 0.
i40e_open() calls i40e_vsi_configure_rx() which configures that field,
but that only happens when interface is up. When it is down, i40e_open()
is not being called, thus vsi->rx_buf_len is not set.
Solution for this is calculate buffer length in newly created
function - i40e_calculate_vsi_rx_buf_len() that return actual buffer
length. Buffer length is being calculated based on the same rules
applied previously in i40e_vsi_configure_rx() function.

sctp: sysctl: make extra pointers netns aware
[ Upstream commit
da05cecc4939c0410d56c29e252998b192756318 ]
Recently, a customer reported that from their container whose
net namespace is different to the host's init_net, they can't set
the container's net.sctp.rto_max to any value smaller than
init_net.sctp.rto_min.
For instance,
Host:
sudo sysctl net.sctp.rto_min
net.sctp.rto_min = 1000
Container:
echo 100 > /mnt/proc-net/sctp/rto_min
echo 400 > /mnt/proc-net/sctp/rto_max
echo: write error: Invalid argument
This is caused by the check made from this'commit
4f3fdf3bc59c
("sctp: add check rto_min and rto_max in sysctl")'
When validating the input value, it's always referring the boundary
value set for the init_net namespace.
Having container's rto_max smaller than host's init_net.sctp.rto_min
does make sense. Consider that the rto between two containers on the
same host is very likely smaller than it for two hosts.
So to fix this problem, as suggested by Marcelo, this patch makes the
extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point
to the corresponding variables from the newly created net namespace while
the new net namespace is being registered in sctp_sysctl_net_register.

ntb_netdev: Use dev_kfree_skb_any() in interrupt context
[ Upstream commit
5f7d78b2b12a9d561f48fa00bab29b40f4616dad ]
TX/RX callback handlers (ntb_netdev_tx_handler(),
ntb_netdev_rx_handler()) can be called in interrupt
context via the DMA framework when the respective
DMA operations have completed. As such, any calls
by these routines to free skb's, should use the
interrupt context safe dev_kfree_skb_any() function.
Previously, these callback handlers would call the
interrupt unsafe version of dev_kfree_skb(). This has
not presented an issue on Intel IOAT DMA engines as
that driver utilizes tasklets rather than a hard
interrupt handler, like the AMD PTDMA DMA driver.
On AMD systems, a kernel WARNING message is
encountered, which is being issued from
skb_release_head_state() due to in_hardirq()
being true.
Besides the user visible WARNING from the kernel,
the other symptom of this bug was that TCP/IP performance
across the ntb_netdev interface was very poor, i.e.
approximately an order of magnitude below what was
expected. With the repair to use dev_kfree_skb_any(),
kernel WARNINGs from skb_release_head_state() ceased
and TCP/IP performance, as measured by iperf, was on
par with expected results, approximately 20 Gb/s on
AMD Milan based server. Note that this performance
is comparable with Intel based servers.

net: amd-xgbe: Check only the minimum speed for active/passive cables
[ Upstream commit
f8ab263d4d48e6dab752029bf562f20a2ee630ed ]
There are cables that exist that can support speeds in excess of 10GbE.
The driver, however, restricts the EEPROM advertised nominal bitrate to
a specific range, which can prevent usage of cables that can support,
for example, up to 25GbE.
Rather than checking that an active or passive cable supports a specific
range, only check for a minimum supported speed.

SFP+ active and passive cables are copper cables with fixed SFP+ end
connectors. Due to a misinterpretation of this, SFP+ active cables could
end up not being recognized, causing the driver to fail to establish a
connection.
Introduce a new enum in SFP+ cable types, XGBE_SFP_CABLE_FIBER, that is
the default cable type, and handle active and passive cables when they are
specifically detected.

Change the behaviour of ip6_datagram_connect to consider the interface
set by the IPV6_UNICAST_IF socket option, similarly to udpv6_sendmsg.
This change is the IPv6 counterpart of the fix for IP_UNICAST_IF.
The tests introduced by that patch showed that the incorrect

This patch fixes the broken test.

bpf: Do not zero-extend kfunc return values
[ Upstream commit
d35af0a7feb077c43ff0233bba5a8c6e75b73e35 ]
In BPF all global functions, and BPF helpers return a 64-bit
value. For kfunc calls, this is not the case, and they can return
e.g. 32-bit values.
The return register R0 for kfuncs calls can therefore be marked as
subreg_def != DEF_NOT_SUBREG. In general, if a register is marked with
subreg_def != DEF_NOT_SUBREG, some archs (where bpf_jit_needs_zext()
returns true) require the verifier to insert explicit zero-extension
instructions.
For kfuncs calls, however, the caller should do sign/zero extension
for return values. In other words, the compiler is responsible to
insert proper instructions, not the verifier.
An example, provided by Yonghong Song:
$ cat t.c
extern unsigned foo(void);
unsigned bar1(void) {
return foo();
}
unsigned bar2(void) {
if (foo()) return 10; else return 20;
}
$ clang -target bpf -mcpu=v3 -O2 -c t.c && llvm-objdump -d t.o
t.o: file format elf64-bpf
Disassembly of section .text:
0000000000000000 <bar1>:
0: 85 10 00 00 ff ff ff ff call -0x1
1: 95 00 00 00 00 00 00 00 exit
0000000000000010 <bar2>:
2: 85 10 00 00 ff ff ff ff call -0x1
3: bc 01 00 00 00 00 00 00 w1 = w0
4: b4 00 00 00 14 00 00 00 w0 = 0x14
5: 16 01 01 00 00 00 00 00 if w1 == 0x0 goto +0x1 <LBB1_2>
6: b4 00 00 00 0a 00 00 00 w0 = 0xa
0000000000000038 <LBB1_2>:
7: 95 00 00 00 00 00 00 00 exit
If the return value of 'foo()' is used in the BPF program, the proper
zero-extension will be done.
Currently, the verifier correctly marks, say, a 32-bit return value as
subreg_def != DEF_NOT_SUBREG, but will fail performing the actual
zero-extension, due to a verifier bug in
opt_subreg_zext_lo32_rnd_hi32(). load_reg is not properly set to R0,
and the following path will be taken:
if (WARN_ON(load_reg == -1)) {
verbose(env, "verifier bug. zext_dst is set, but no reg is defined\n");
return -EFAULT;
}
A longer discussion from v1 can be found in the link below.
Correct the verifier by avoiding doing explicit zero-extension of R0
for kfunc calls. Note that R0 will still be marked as a sub-register
for return values smaller than 64-bit.

[ Upstream commit
3a6f994f848a69deb2bf3cd9d130dd0c09730e55 ]
The addition of 3WIRE support would affect MOSI direction even
when still in standard (4 wire) mode. This can lead to MOSI being
at an invalid logic level when a device driver sets an SPI
message with a NULL tx_buf.
spi.h states that if tx_buf is NULL then "zeros will be shifted
out ... " If MOSI is tristated then the data shifted out is subject
to pull resistors, keepers, or in the absence of those, noise.
This issue came to light when using spi-gpio connected to an
ADS7843 touchscreen controller. MOSI pulled high when clocking
MISO data in caused the SPI device to interpret this as a command
which would put the device in an unexpected and non-functional
state.

mmc: atmel-mci: fix return value check of mmc_add_host()
[ Upstream commit
9e6e8c43726673ca2abcaac87640b9215fd72f4c ]
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
So fix this by checking the return value and calling mmc_free_host()
in the error path.

hwmon: (emc2305) fix pwm never being able to set lower
[ Upstream commit
364ffd2537c44cb6914ff5669153f4a86fffad29 ]
There are fields 'last_hwmon_state' and 'last_thermal_state' in the
structure 'emc2305_cdev_data', which respectively store the cooling state
set by the 'hwmon' and 'thermal' subsystem, and the driver author hopes
that if the state set by 'hwmon' is lower than the value set by 'thermal',
the driver will just save it without actually setting the pwm. Currently,
the 'last_thermal_state' also be updated by 'hwmon', which will cause the
cooling state to never be set to a lower value. This patch fixes that.
