a76053707d dev_ioctl: split out ndo_eth_ioctl
Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.

Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

This is a purely cosmetic change intended to help readers find
their way through the implementation.

ef17e2ac21 net: qed: remove unneeded return variables
Some return variables are never changed until function returned.
These variables are unneeded for their functions. Therefore, the
unneeded return variables can be removed safely by returning their
initial values.

92766c4628 net/qla3xxx: fix schedule while atomic in ql_wait_for_drvr_lock and ql_adapter_reset
When calling the 'ql_wait_for_drvr_lock' and 'ql_adapter_reset', the driver
has already acquired the spin lock, so the driver should not call 'ssleep'
in atomic context.

This bug can be fixed by using 'mdelay' instead of 'ssleep'.

8ec035ac4a fallthrough fixes for Clang for 5.14-rc1
Hi Linus,
 
 Please, pull the following patches that fix many fall-through warnings
 when building with Clang 12.0.0 and this[1] change reverted. Notice
 that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
 is meant to be reverted at some point. So, these patches help to move
 in that direction.
 
 Thanks!

4415db6ca8 qede: Remove rcu_read_lock() around XDP program invocation
The qede driver has rcu_read_lock()/rcu_read_unlock() pairs around XDP
program invocations. However, the actual lifetime of the objects referred
by the XDP program invocation is longer, all the way through to the call to
xdp_do_flush(), making the scope of the rcu_read_lock() too small. This
turns out to be harmless because it all happens in a single NAPI poll
cycle (and thus under local_bh_disable()), but it makes the rcu_read_lock()
misleading.

Rather than extend the scope of the rcu_read_lock(), just get rid of it
entirely. With the addition of RCU annotations to the XDP_REDIRECT map
types that take bh execution into account, lockdep even understands this to
be safe, so there's really no reason to keep it around.

1c200f832e net: qed: Fix memcpy() overflow of qed_dcbx_params()
The source (&dcbx_info->operational.params) and dest
(&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params
(560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used
as the memcpy() size.

However it seems that struct qed_dcbx_operational_params
(dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params
(p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte
for "valid").

On the assumption that the size is wrong (rather than the source structure
type), adjust the memcpy() size argument to be 4 bytes smaller and add
a BUILD_BUG_ON() to validate any changes to the structure sizes.

13a6f31539 net/qla3xxx: fix schedule while atomic in ql_sem_spinlock
When calling the 'ql_sem_spinlock', the driver has already acquired the
spin lock, so the driver should not call 'ssleep' in atomic context.

This bug can be fixed by using 'mdelay' instead of 'ssleep'.

84460f01cb qlcnic: Add null check after calling netdev_alloc_skb
The function qlcnic_dl_lb_test() currently calls netdev_alloc_skb()
without checking afterwards that the allocation succeeded. Fix this by
checking if the skb is NULL and returning an error in such a case.
Breaking out of the loop if the skb is NULL is not correct as no error
would be reported to the caller and no message would be printed for the
user.

b95b57dfe7 Revert "qlcnic: Avoid potential NULL pointer dereference"
This reverts commit 5bf7295fe34a5251b1d241b9736af4697b590670.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted.  It will be fixed up "correctly" in a
later kernel change.

This commit does not properly detect if an error happens because the
logic after this loop will not detect that there was a failed
allocation.

1ec3d02f9c qede: Remove a erroneous ++ in 'qede_rx_build_jumbo()'
This ++ is confusing. It looks duplicated with the one already performed in
'skb_fill_page_desc()'.

In fact, it is harmless. 'nr_frags' is written twice with the same value.
Once, because of the nr_frags++, and once because of the 'nr_frags = i + 1'
in 'skb_fill_page_desc()'.

So axe this post-increment to avoid confusion.

fdc13979f9 bpf, devmap: Move drop error path to devmap for XDP_REDIRECT
We want to change the current ndo_xdp_xmit drop semantics because it will
allow us to implement better queue overflow handling. This is working
towards the larger goal of a XDP TX queue-hook. Move XDP_REDIRECT error
path handling from each XDP ethernet driver to devmap code. According to
the new APIs, the driver running the ndo_xdp_xmit pointer, will break tx
loop whenever the hw reports a tx error and it will just return to devmap
caller the number of successfully transmitted frames. It will be devmap
responsibility to free dropped frames.

Move each XDP ndo_xdp_xmit capable driver to the new APIs:

- veth
- virtio-net
- mvneta
- mvpp2
- socionext
- amazon ena
- bnxt
- freescale (dpaa2, dpaa)
- xen-frontend
- qede
- ice
- igb
- ixgbe
- i40e
- mlx5

41fb4c1ba7 net/qla3xxx: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'ql_alloc_net_req_rsp_queues()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see below)

When memory is allocated in 'ql_alloc_buffer_queues()' GFP_KERNEL can be
used because this flag is already used just a few line above.

When memory is allocated in 'ql_alloc_small_buffers()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see above)

When memory is allocated in 'ql_alloc_mem_resources()' GFP_KERNEL can be
used because this function already calls 'ql_alloc_buffer_queues()' which
uses GFP_KERNEL. (see above)

While at it, use 'dma_set_mask_and_coherent()' instead of 'dma_set_mask()/
dma_set_coherent_mask()' in order to slightly simplify code.

1) Extend atomic operations to the BPF instruction set along with x86-64 JIT support,
   that is, atomic{,64}_{xchg,cmpxchg,fetch_{add,and,or,xor}}, from Brendan Jackman.

2) Add support for using kernel module global variables (__ksym externs in BPF
   programs) retrieved via module's BTF, from Andrii Nakryiko.

3) Generalize BPF stackmap's buildid retrieval and add support to have buildid
   stored in mmap2 event for perf, from Jiri Olsa.

4) Various fixes for cross-building BPF sefltests out-of-tree which then will
   unblock wider automated testing on ARM hardware, from Jean-Philippe Brucker.

5) Allow to retrieve SOL_SOCKET opts from sock_addr progs, from Daniel Borkmann.

6) Clean up driver's XDP buffer init and split into two helpers to init per-
   descriptor and non-changing fields during processing, from Lorenzo Bianconi.

7) Minor misc improvements to libbpf & bpftool, from Ian Rogers.

297af515d7 netxen_nic: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'netxen_get_minidump_template()' GFP_KERNEL can
be used because its only caller, ' netxen_setup_minidump(()' already uses
it and no lock is acquired in the between.

When memory is allocated in other function in 'netxen_nic_ctx.c' GFP_KERNEL
can be used because the call chain already uses GFP_KERNEL and no lock is
taken in the between.
The call chain is:
  netxen_nic_attach()

    --> netxen_alloc_hw_resources()
      --> nx_fw_cmd_create_rx_ctx()
      --> nx_fw_cmd_create_tx_ctx()

When memory is allocated in 'netxen_init_dummy_dma()' GFP_KERNEL can be
used because its only call chain already uses it and no lock is acquired in
the between.
The call chain is:
  --> netxen_start_firmware
    --> netxen_request_firmware()
