net/sched: two fixes for cls_u32
One syzbot report brought my attention to cls_u32.
This series addresses the syzbot report, and an additional
issue discovered in code review.

While investigating a related syzbot report,
I found that whenever call to tcf_exts_init()
from u32_init_knode() is failing, we end up
with an elevated refcount on ht->refcnt
To avoid that, only increase the refcount after
all possible errors have been evaluated.

Intel Wired LAN Driver Updates 2022-04-13
This series contains updates to igc and e1000e drivers.
Sasha removes waiting for hardware semaphore as it could cause an
infinite loop and changes usleep_range() calls done under atomic
context to udelay() for igc. For e1000e, he changes some variables from
u16 to u32 to prevent possible overflow of values.
Vinicius disables PTM when going to suspend as it is causing hang issues
on some platforms for igc.

The GPI DMA engine driver can be compiled as a module, in which case the
likely probe deferral "error" shows up in the kernel log. Switch to
using dev_err_probe() to silence this warning and to ensure that
"devices_deferred" in debugfs carries this information.

The i.MX8MP Mask Set Errata for Mask 1P33A, Rev. 2.0 has description of
errata ERR007805 as below. This errata is found on all MX8M{M,N,P,Q},
MX7{S,D}, MX6{UL{,L,Z},S{,LL,X},S,D,DL,Q,DP,QP} . MX7ULP, MX8Q, MX8X
are not affected. MX53 and older status is unknown, as the errata
first appears in MX6 errata sheets from 2016 and the latest errata
sheet for MX53 is from 2015. Older SoC errata sheets predate the
MX53 errata sheet. MX8ULP and MX9 status is unknown as the errata

ERR007805 I2C: When the I2C clock speed is configured for 400 kHz,
the SCL low period violates the I2C spec of 1.3 uS min
Description: When the I2C module is programmed to operate at the
maximum clock speed of 400 kHz (as defined by the I2C spec), the SCL
clock low period violates the I2C spec of 1.3 uS min. The user must
reduce the clock speed to obtain the SCL low time to meet the 1.3us
I2C minimum required. This behavior means the SoC is not compliant
to the I2C spec at 400kHz.
Workaround: To meet the clock low period requirement in fast speed
mode, SCL must be configured to 384KHz or less.
"
Implement the workaround by matching on the affected SoC specific
compatible strings and by limiting the maximum bus frequency in case
the SoC is affected.

Wait for completion of write transfers before returning from the driver.
At first sight it may seem advantageous to leave write transfers queued
for the controller to carry out on its own time, but there's a couple of
issues with it:
* Driver doesn't check for FIFO space.
* The queued writes can complete while the driver is in its I2C read
transfer path which means it will get confused by the raising of
XEN (the 'transaction ended' signal). This can cause a spurious
ENODATA error due to premature reading of the MRXFIFO register.
Adding the wait fixes some unreliability issues with the driver. There's
some efficiency cost to it (especially with pasemi_smb_waitready doing
its polling), but that will be alleviated once the driver receives
interrupt support.

The commit 92986f6b4c ("dm: use bio_clone_fast in alloc_io/alloc_tio")
removed bio_clone_fast() call from alloc_tio() when ci->io->tio is
available. In this case, ci->bio is not copied to ci->io->tio.clone.
This is fine since init_clone_info() sets same values to ci->bio and
ci->io->tio.clone.
However, when incoming bios have REQ_PREFLUSH flag, __send_empty_flush()
prepares a zero length bio on stack and set it to ci->bio. At this time,
ci->io->tio.clone still keeps non-zero length. When alloc_tio() chooses
this ci->io->tio.clone as the bio to map, it is passed to targets as
non-empty flush bio. It causes bio length check failure in dm-zoned and
unexpected operation such as dm_accept_partial_bio() call.
To avoid the non-empty flush bio, set zero length to ci->io->tio.clone
in __send_empty_flush().

Given a sufficiently large number of actions, while copying and
reserving memory for a new action of a new flow, if next_offset is
greater than MAX_ACTIONS_BUFSIZE, the function reserve_sfa_size() does
not return -EMSGSIZE as expected, but it allocates MAX_ACTIONS_BUFSIZE
bytes increasing actions_len by req_size. This can then lead to an OOB
write access, especially when further actions need to be copied.
Fix it by rearranging the flow action size check.

The following sequence of events caused the BUG:
1. During ip6gretap device initialization, tunnel->tun_hlen (e.g. 4) is
calculated based on old flags (see ip6gre_calc_hlen());
2. packet_snd() reserves header room for skb A, assuming
tunnel->tun_hlen is 4;
3. Later (in clsact Qdisc), the eBPF program sets a new tunnel key for
skb A using bpf_skb_set_tunnel_key() (see _ip6gretap_set_tunnel());
4. __gre6_xmit() detects the new tunnel key, and recalculates
"tun_hlen" (e.g. 12) based on new flags (e.g. TUNNEL_KEY and
TUNNEL_SEQ);
5. gre_build_header() calls skb_push() with insufficient reserved header
room, triggering the BUG.
As sugguested by Cong, fix it by moving the call to skb_cow_head() after
the recalculation of tun_hlen.

A recent patch[1] from Eric Dumazet flipped the order in which the
keepalive timer and the keepalive worker were cancelled in order to fix a
syzbot reported issue[2]. Unfortunately, this enables the mirror image bug
whereby the timer races with rxrpc_exit_net(), restarting the worker after
it has been cancelled:
CPU 1 CPU 2
=============== =====================
if (rxnet->live)
<INTERRUPT>
rxnet->live = false;
cancel_work_sync(&rxnet->peer_keepalive_work);
rxrpc_queue_work(&rxnet->peer_keepalive_work);
del_timer_sync(&rxnet->peer_keepalive_timer);
Fix this by restoring the removed del_timer_sync() so that we try to remove
the timer twice. If the timer runs again, it should see ->live == false
and not restart the worker.

The intent behind commit e6fc9f62ce ("dm: flag clones created by
__send_duplicate_bios") was to formally disallow the use of
dm_accept_partial_bio() where it simply isn't possible -- due to
constraint that multiple bios cannot meaningfully update a shared
tio->len_ptr.
But that commit went too far and disallowed the case where "abormal"
IO (e.g. WRITE_ZEROES) is only using a single bio. Fix this by
not marking a dm_io with a single dm_target_io (and bio), that happens
to be created by __send_duplicate_bios, as DM_TIO_IS_DUPLICATE_BIO.
Also remove 'unsigned *len' parameter from alloc_multiple_bios().
This commit fixes a dm_accept_partial_bio() BUG_ON() with dm-zoned
when a WRITE_ZEROES bio is issued.

When asked to create a path ending '/', but which is not to be a
directory (LOOKUP_DIRECTORY not set), filename_create() will never try
to create the file. If it doesn't exist, -ENOENT is reported.
However, it still passes LOOKUP_CREATE|LOOKUP_EXCL to the filesystems
->lookup() function, even though there is no intent to create. This is
misleading and can cause incorrect behaviour.
If you try
ln -s foo /path/dir/
where 'dir' is a directory on an NFS filesystem which is not currently
known in the dcache, this will fail with ENOENT.
But as the name is not in the dcache, nfs_lookup gets called with
LOOKUP_CREATE|LOOKUP_EXCL and so it returns NULL without performing any
lookup, with the expectation that a subsequent call to create the target
will be made, and the lookup can be combined with the creation. In the
case with a trailing '/' and no LOOKUP_DIRECTORY, that call is never
made. Instead filename_create() sees that the dentry is not (yet)
positive and returns -ENOENT - even though the directory actually
exists.
So only set LOOKUP_CREATE|LOOKUP_EXCL if there really is an intent to
create, and use the absence of these flags to decide if -ENOENT should
be returned.
Note that filename_parentat() is only interested in LOOKUP_REVAL, so we
split that out and store it in 'reval_flag'. __lookup_hash() then gets
reval_flag combined with whatever create flags were determined to be
needed.

This became an unexpectedly large pull request due to various
regression fixes in the previous kernels.
The majority of fixes are a series of patches to address the
regression at probe errors in devres'ed drivers, while there are
yet more fixes for the x86 SG allocations and for USB-audio
buffer management. In addition, a few HD-audio quirks and other
small fixes are found.
