When I fixed IGMPv3/MLDv2 to use the bridge's multicast_membership_interval
value which is chosen by user-space instead of calculating it based on
multicast_query_interval and multicast_query_response_interval I forgot
to update the selftests relying on that behaviour. Now we have to
manually set the expected GMI value to perform the tests correctly and get
proper results (similar to IGMPv2 behaviour).

Function br_get_link_af_size_filtered() calls br_cfm_{,peer}_mep_count()
that return a count. When BRIDGE_CFM is not enabled these functions
simply return -EOPNOTSUPP but do not modify count parameter and
calling function then works with uninitialized variables.
Modify these inline functions to return zero in count parameter.

mvneta does not support asymetric pause modes, and it flags this by the
lack of AsymPause in the supported field. When setting pause modes, we
check that pause->rx_pause == pause->tx_pause, but only when pause
autoneg is enabled. When pause autoneg is disabled, we still allow
pause->rx_pause != pause->tx_pause, which is incorrect when the MAC
does not support asymetric pause, and causes mvneta to issue a warning.
Fix this by removing the test for pause->autoneg, so we always check
that pause->rx_pause == pause->tx_pause for network devices that do not
support AsymPause.

When port is linked down, the process which has acquired rtnl_lock
will wait for the in-progress dim work to finish, and the work also
acquires rtnl_lock, which may cause deadlock.
Currently IRQ_MOD registers can be configured by `ethtool -C` and
dim work, and which will take effect depends on the execution order,
rtnl_lock is useless here, so remove them.

For each rate change command submission, the FW has to do a phy

sctp: a couple of fixes for PLPMTUD
Four fixes included in this patchset:
- fix the packet sending in Error state.

sctp_transport_pl_toobig() supposes to return true only if there's
pathmtu update, so that in sctp_icmp_frag_needed() it would call
sctp_assoc_sync_pmtu() and sctp_retransmit(). This patch is to fix
these return places in sctp_transport_pl_toobig().

sctp_transport_pl_hlen() is called to calculate the outer header length
for PL. However, as the Figure in rfc8899#section-4.4:
Any additional
headers .--- MPS -----.
| | |
v v v
+------------------------------+
| IP | ** | PL | protocol data |

<----- PLPMTU ----->
<---------- PMTU -------------->
Outer header are IP + Any additional headers, which doesn't include
Packetization Layer itself header, namely sctphdr, whereas sctphdr
is counted by __sctp_mtu_payload().
The incorrect calculation caused the link pathmtu to be set larger
than expected by t->pl.pmtu + sctp_transport_pl_hlen(). This patch
is to fix it by subtracting sctphdr len in sctp_transport_pl_hlen().

sctp_transport_pl_update() is called when transport update its dst and
pathmtu, instead of stopping the PLPMTUD probe timer, PLPMTUD should
start over and reset the probe timer. Otherwise, the PLPMTUD service
would stop.

Currently when PLPMTUD enters Error state, transport pathmtu will be set
to MIN_PLPMTU(512) while probe is continuing with BASE_PLPMTU(1200). It
will cause pathmtu to stay in a very small value, even if the real pmtu
is some value like 1000.
RFC8899 doesn't clearly say how to set the value in Error state. But one
possibility could be keep using BASE_PLPMTU for the real pmtu, but allow
to do IP fragmentation when it's in Error state.
As it says in rfc8899#section-5.4:
Some paths could be unable to sustain packets of the BASE_PLPMTU
size. The Error State could be implemented to provide robustness to
such paths. This allows fallback to a smaller than desired PLPMTU
rather than suffer connectivity failure. This could utilize methods
such as endpoint IP fragmentation to enable the PL sender to
communicate using packets smaller than the BASE_PLPMTU.
This patch is to set pmtu to BASE_PLPMTU instead of MIN_PLPMTU for Error
state in sctp_transport_pl_send/toobig(), and set packet ipfragok for
non-probe packets when it's in Error state.

Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.
Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12
characters to print the list of LFs of each block for a PF/VF. If the
length of list of LFs of a block exceeds this fixed width then the list
gets truncated and displays only a part of the list. This patch fixes
this by using the maximum possible length of list of LFs among all
blocks of all PFs and VFs entries as the width size.

sk->sk_err appears to expect a positive value, a convention that ktls
doesn't always follow and that leads to memory corruption in other code.
For instance,
[kworker]
tls_encrypt_done(..., err=<negative error from crypto request>)
tls_err_abort(.., err)
sk->sk_err = err;
[task]
splice_from_pipe_feed
...
tls_sw_do_sendpage
if (sk->sk_err) {
ret = -sk->sk_err; // ret is positive
splice_from_pipe_feed (continued)
ret = actor(...) // ret is still positive and interpreted as bytes
// written, resulting in underflow of buf->len and
// sd->len, leading to huge buf->offset and bogus
// addresses computed in later calls to actor()
Fix all tls_err_abort() callers to pass a negative error code
consistently and centralize the error-prone sign flip there, throwing in
a warning to catch future misuse and uninlining the function so it
really does only warn once.

The value of llc_testlink_time is set to the value stored in
net->ipv4.sysctl_tcp_keepalive_time when linkgroup init. The value of
sysctl_tcp_keepalive_time is already jiffies, so we don't need to
multiply by HZ, which would cause smc_link->llc_testlink_time overflow,

MTU change is refused whenever the value of new MTU is bigger than
the max packet bytes that fits in NFP Cluster Target Memory (CTM).
However, an eBPF program doesn't always need to access the whole
packet data.
The maximum direct packet access (DPA) offset has always been
caculated by verifier and stored in the max_pkt_offset field of prog
aux data.

When the syscall trace points are not configured in, the kselftests for
ftrace will try to attach an event probe (eprobe) to one of the system
call trace points. This triggered a WARNING, because the failure only
expects to see memory issues. But this is not the only failure. The user
may attempt to attach to a non existent event, and the kernel must not
warn about it.

This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL,
which in turn enables NIOS2_DTB_SOURCE. This causes the build error
