952fcfd08c net: remove type_check from dev_get_nest_level()
The idea for type_check in dev_get_nest_level() was to count the number
of nested devices of the same type (currently, only macvlan or vlan
devices).
This prevented the false positive lockdep warning on configurations such
as:

eth0 <--- macvlan0 <--- vlan0 <--- macvlan1

However, this doesn't prevent a warning on a configuration such as:

eth0 <--- macvlan0 <--- vlan0
eth1 <--- vlan1 <--- macvlan1

In this case, all the locks end up with a nesting subclass of 1, so
lockdep thinks that there is still a deadlock:

- in the first case we have (macvlan_netdev_addr_lock_key, 1) and then
  take (vlan_netdev_xmit_lock_key, 1)
- in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then
  take (macvlan_netdev_addr_lock_key, 1)

By removing the linktype check in dev_get_nest_level() and always
incrementing the nesting depth, lockdep considers this configuration
valid.

bc561632dd net: ipv6: Do not keep IPv6 addresses when IPv6 is disabled
If IPv6 is disabled when the option is set to keep IPv6
addresses on link down, userspace is unaware of this as
there is no such indication via netlink. The solution is to
remove the IPv6 addresses in this case, which results in
netlink messages indicating removal of addresses in the
usual manner. This fix also makes the behavior consistent
with the case of having IPv6 disabled first, which stops
IPv6 addresses from being added.

54236ab09e net/sctp: always initialise sctp_ht_iter::start_fail
sctp_transport_seq_start() does not currently clear iter->start_fail on
success, but relies on it being zero when it is allocated (by
seq_open_net()).

This can be a problem in the following sequence:

    open() // allocates iter (and implicitly sets iter->start_fail = 0)
    read()
     - iter->start() // fails and sets iter->start_fail = 1
     - iter->stop() // doesn't call sctp_transport_walk_stop() (correct)
    read() again
     - iter->start() // succeeds, but doesn't change iter->start_fail
     - iter->stop() // doesn't call sctp_transport_walk_stop() (wrong)

We should initialize sctp_ht_iter::start_fail to zero if ->start()
succeeds, otherwise it's possible that we leave an old value of 1 there,
which will cause ->stop() to not call sctp_transport_walk_stop(), which
causes all sorts of problems like not calling rcu_read_unlock() (and
preempt_enable()), eventually leading to more warnings like this:

The bug seems to have been around since forever.

There's more problems with missing error checks in iriap_init() (and
indeed all of irda_init()), but that's a bigger problem that needs
very careful review and testing. This patch will fix the most serious
bug (as it's easily reached from unprivileged userspace).

I have tested my patch with a reproducer.

0ed661d5a4 bpf: fix write helpers with regards to non-linear parts
Fix the bpf_try_make_writable() helper and all call sites we have in BPF,
it's currently defect with regards to skbs when the write_len spans into
non-linear parts, no matter if cloned or not.

There are multiple issues at once. First, using skb_store_bits() is not
correct since even if we have a cloned skb, page frags can still be shared.
To really make them private, we need to pull them in via __pskb_pull_tail()
first, which also gets us a private head via pskb_expand_head() implicitly.

This is for helpers like bpf_skb_store_bytes(), bpf_l3_csum_replace(),
bpf_l4_csum_replace(). Really, the only thing reasonable and working here
is to call skb_ensure_writable() before any write operation. Meaning, via
pskb_may_pull() it makes sure that parts we want to access are pulled in and
if not does so plus unclones the skb implicitly. If our write_len still fits
the headlen and we're cloned and our header of the clone is not writable,
then we need to make a private copy via pskb_expand_head(). skb_store_bits()
is a bit misleading and only safe to store into non-linear data in different
contexts such as 357b40a18b ("[IPV6]: IPV6_CHECKSUM socket option can
corrupt kernel memory").

For above BPF helper functions, it means after fixed bpf_try_make_writable(),
we've pulled in enough, so that we operate always based on skb->data. Thus,
the call to skb_header_pointer() and skb_store_bits() becomes superfluous.
In bpf_skb_store_bytes(), the len check is unnecessary too since it can
only pass in maximum of BPF stack size, so adding offset is guaranteed to
never overflow. Also bpf_l3/4_csum_replace() helpers must test for proper
offset alignment since they use __sum16 pointer for writing resulting csum.

The remaining helpers that change skb data not discussed here yet are
bpf_skb_vlan_push(), bpf_skb_vlan_pop() and bpf_skb_change_proto(). The
vlan helpers internally call either skb_ensure_writable() (pop case) and
skb_cow_head() (push case, for head expansion), respectively. Similarly,
bpf_skb_proto_xlat() takes care to not mangle page frags.

Fixes: 91bc4822c3 ("tc: bpf: add checksum helpers")

This per-subsystem series is part of a tree wide cleanup. usb_alloc_urb() uses
kmalloc which already prints enough information on failure. So, let's simply
remove those "allocation failed" messages from drivers like we did already for
other -ENOMEM cases. gkh acked this approach when we talked about it at LCJ in

a31eb63a0a Merge branch 'thunderx-next'
Sunil Goutham says:

====================
net: thunderx: Support for newer chips and miscellaneous patches

This patch series adds support for VNIC on 81xx and 83xx SOCs.
81xx/83xx is different from 88xx in terms of capabilities and new type
of interfaces supported (eg: QSGMII, RGMII) and have DLMs instead of
QLMs which allows single BGX to have interfaces of different LMAC types.

Also included some patches which are common for all 88xx/81xx/83xx
SOCs like using netdev's name while registering irqs, reset receive
queue stats and some changes to use standard API for split buffer Rx
packets, generating RSS key e.t.c

PS: Most of the patches were submitted earlier under different series but
for some reason were not picked up by patchwork. Since new patches have been
added in the meantime, resubmitting all as a new patchset.

Changes from v1:
- Incorporated Yuval Mintz's suggestion to use generic API to set minimum
  queue count i.e by using netif_get_num_default_rss_queues().
- Resolved a compilation issue reported by test robot while compiling
  patch 'Add support for 16 LMACs of 83xx'

93db2cf8ca net: thunderx: Don't set RX_PACKET_DIS while initializing
Setting BGXX_SPUX_MISC_CONTROL::RX_PACKET_DIS is not needed as
packet reception is anyway disabled by BGXX_CMRX_CONFIG::DATA_PKT_RX_EN.
Also setting RX_PACKET_DIS causes a bogus remote fault condition
which delays link detection.

3458c40d60 net: thunderx: Reset RXQ HW stats when interface is brought down
When SQ/TXQ is reclaimed i.e reset it's stats also automatically reset
by HW. This is not the case with RQ. Also VF doesn't have write access
to statistics counter registers. Hence a new Mbox msg is introduced which
supports resetting RQ, SQ and full Qset stats. Currently only RQ stats
are being reset using this mbox message.

On 88xx all LMACs in a BGX will be in same mode but on 81xx
BGX can be split as two and there can be LMACs configured in

These changes move lmac_type, lane2serdes fields into per lmac
struct from BGX struct. Got rid of qlm_mode field which has become
redundant with these changes. And now no of valid LMACs is read
from CSRs configured by low level firmware and figuring out the
same based on QLM mode is discarded
