The Microchip ENC28J60 SPI Ethernet driver schedules a work item from
the interrupt handler because accesses to the SPI bus may sleep.

On PREEMPT_RT (which forces interrupt handling into threads) this
old-fashioned approach unnecessarily increases latency because an
interrupt results in first waking the interrupt thread, then scheduling
the work item.  So, a double indirection to handle an interrupt.

Avoid by converting the driver to modern threaded interrupt handling.

net: mvneta: reduce size of TSO header allocation

With reference to
https://forum.turris.cz/t/random-kernel-exceptions-on-hbl-tos-7-0/18865/
https://github.com/openwrt/openwrt/pull/12375#issuecomment-1528842334

It appears that mvneta attempts an order-6 allocation for the TSO
header memory. While this succeeds early on in the system's life time,
trying order-6 allocations later can result in failure due to memory
fragmentation.

Firstly, the reason it's so large is that we take the number of
transmit descriptors, and allocate a TSO header buffer for each, and
each TSO header is 256 bytes. The driver uses a simple mechanism to
determine the address - it uses the transmit descriptor index as an
index into the TSO header memory.

	(The first obvious question is: do there need to be this
	many? Won't each TSO header always have at least one bit
	of data to go with it? In other words, wouldn't the maximum
	number of TSO headers that a ring could accept be the number
	of ring entries divided by 2?)

There is no real need for this memory to be an order-6 allocation,
since nothing in hardware requires this buffer to be contiguous.

Therefore, this series splits this order-6 allocation up into 32
order-1 allocations (8k pages on 4k page platforms), each giving
32 TSO headers per page.

In order to do this, these patches:

1) fix a horrible transmit path error-cleanup bug - the existing
   code unmaps from the first descriptor that was allocated at
   interface bringup, not the first descriptor that the packet
   is using, resulting in the wrong descriptors being unmapped.

2) since xdp support was added, we now have buf->type which indicates
   what this transmit buffer contains. Use this to mark TSO header
   buffers.

3) get rid of IS_TSO_HEADER(), instead using buf->type to determine
   whether this transmit buffer needs to be DMA-unmapped.

4) move tso_build_hdr() into mvneta_tso_put_hdr() to keep all the
   TSO header building code together.

5) split the TSO header allocation into chunks of order-1 pages.

This has now been tested by the Turris folk and has been found to fix
the allocation error.

Now that we no longer need to check whether the DMA address is within
the TSO header DMA memory range for the queue, we can allocate the TSO
header DMA memory in chunks rather than one contiguous order-6 chunk,
which can stress the kernel's memory subsystems to allocate.

Instead, use order-1 (8k) allocations, which will result in 32 order-1
pages containing 32 TSO headers.

Now that we use a different buffer type for TSO headers, we can use
buf->type to determine whether the original buffer was DMA-mapped or
not. The rules are:

	MVNETA_TYPE_XDP_TX - from a DMA pool, no unmap is required
	MVNETA_TYPE_XDP_NDO - dma_map_single()'d
	MVNETA_TYPE_SKB - normal skbuff, dma_map_single()'d
	MVNETA_TYPE_TSO - from the TSO buffer area

This means we only need to call dma_unmap_single() on the XDP_NDO and
SKB types of buffer, and we no longer need the private IS_TSO_HEADER()
which relies on the TSO region being contiguously allocated.

Currently the SYN RTO schedule follows an exponential backoff
scheme, which can be unnecessarily conservative in cases where
there are link failures. In such cases, it's better to
aggressively try to retransmit packets, so it takes routers
less time to find a repath with a working link.

We chose a default value for this sysctl of 4, to follow
the macOS and IOS backoff scheme of 1,1,1,1,1,2,4,8, ...
MacOS and IOS have used this backoff schedule for over
a decade, since before this 2009 IETF presentation
discussed the behavior:
https://www.ietf.org/proceedings/75/slides/tcpm-1.pdf

This commit makes the SYN RTO schedule start with a number of
linear backoffs given by the following sysctl:
* tcp_syn_linear_timeouts

This changes the SYN RTO scheme to be: init_rto_val for
tcp_syn_linear_timeouts, exp backoff starting at init_rto_val

For example if init_rto_val = 1 and tcp_syn_linear_timeouts = 2, our
backoff scheme would be: 1, 1, 1, 2, 4, 8, 16, ...

It's been a few years since we've sorted this thing, and the end result
is that we've added MAINTAINERS entries in the wrong order, and a number
of entries have their fields in non-canonical order too.

So roll this boulder up the hill one more time by re-running

   ./scripts/parse-maintainers.pl --order

on it.

This file ends up being fairly painful for merge conflicts even
normally, since unlike almost all other kernel files it's one of those
"everybody touches the same thing", and re-ordering all entries is only
going to make that worse.  But the alternative is to never do it at all,
and just let it all rot..

The rc2 week is likely the quietest and least painful time to do this.

The call to gfs2_trans_begin is done because the truncate_inode_pages
call can cause gfs2 events that require a transaction, such as removing
journaled data (jdata) blocks from the journal.

This patch fixes the problem by adding a check for sdp->sd_jdesc to
function gfs2_evict_inode. In theory, this should only happen to corrupt
gfs2 file systems, when gfs2 detects the problem, reports it, then tries

Commit d4c36765 ("net: mscc: ocelot: keep ocelot_stat_layout by reg
address, not offset") organized the stats counters for Ocelot chips, namely
the VSC7512 and VSC7514. A few of the counter offsets were incorrect, and
were caught by this warning:

WARNING: CPU: 0 PID: 24 at drivers/net/ethernet/mscc/ocelot_stats.c:909
ocelot_stats_init+0x1fc/0x2d8
reg 0x5000078 had address 0x220 but reg 0x5000079 has address 0x214,
bulking broken!

Fix these register offsets.

The 'sched' index value must be checked before accessing an element
of the 'sctp_sched_ops' array. Otherwise, it can lead to OOB access.

Note that it's harmless since the 'sched' parameter is checked before
calling 'sctp_sched_set_sched'.

Now macsec on top of vlan can be offloaded to macsec offloading
devices so that VLAN tag is sent in clear text on wire i.e,
packet structure is DMAC|SMAC|VLAN|SECTAG. Offloading devices can
simply enable NETIF_F_HW_MACSEC feature in netdev->vlan_features for
this to work. But the logic in offloading drivers to retrieve the
private structure from netdev needs to be changed to check whether
the netdev received is real device or a vlan device and get private
structure accordingly. This patch changes the offloading drivers to
use helper macsec_netdev_priv instead of netdev_priv.

If skb enqueue the qdisc, fq_skb_cb(skb)->time_to_send is changed which
is actually skb->cb, and IPCB(skb_in)->opt will be used in
__ip_options_echo. It is possible that memcpy is out of bounds and lead
to stack overflow.
We should clear skb->cb before ip_local_out or ip6_local_out.

v2:
1. clean the stack info
2. use IPCB/IP6CB instead of skb->cb

crash on stable-5.10(reproduce in kasan kernel).

Before blamed commit, pskb_may_pull() was used instead
of skb_header_pointer() in __vlan_get_protocol() and friends.

Few callers depended on skb->head being populated with MAC header,
syzbot caught one of them (skb_mac_gso_segment())

Add vlan_get_protocol_and_depth() to make the intent clearer
and use it where sensible.

This is a more generic fix than commit e9d3f809
("net/af_packet: make sure to pull mac header") which was
dealing with a similar issue.

__condition is evaluated twice in sk_wait_event() macro.

First invocation is lockless, and reads can race with writes,
as spotted by syzbot.

BUG: KCSAN: data-race in sk_stream_wait_connect / tcp_disconnect

do_recvmmsg() can write to sk->sk_err from multiple threads.

As said before, many other points reading or writing sk_err
need annotations.

Since veth is very likely to be enabled and there are some drivers
(e.g. mlx5) where CONFIG_PAGE_POOL_STATS is optional, make
CONFIG_PAGE_POOL_STATS optional for veth too in order to keep it
optional instead of required.
