   - A fix for amount of memory on Beaglebone Black. Surfaced now since

      firestream: fix memory leaks · fa865ba1
      Wenwen Wang authored 
      In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.

To fix this issue, deallocate 'vcc' before the error code is returned.

  The extra fixup patch is there to silence an unnecessary warning"

Mellanox, mlx5 fixes 2020-01-24

This series introduces some fixes to mlx5 driver.

Please pull and let me know if there is any problem.

Merge conflict: once merge with net-next, a contextual conflict will
appear in drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c
since the code moved in net-next.
To resolve, just delete ALL of the conflicting hunk from net.
So sorry for the small mess ..

For -stable v5.4:
 ('net/mlx5: Update the list of the PCI supported devices')
 ('net/mlx5: Fix lowest FDB pool size')
 ('net/mlx5e: kTLS, Fix corner-case checks in TX resync flow')
 ('net/mlx5e: kTLS, Do not send decrypted-marked SKBs via non-accel path')

caused by the previous patch ("btrfs: scrub: Require mandatory block
group RO for dev-replace"). Hitting ENOSPC is possible and could happen
when the block group is set read-only, preventing NOCOW writes to the
area that's being accessed by dev-replace.

This has happend with scratch devices of size 12G but not with 5G and
20G, so this is depends on timing and other activity on the filesystem.
The whole replace operation is restartable, the space state should be
examined by the user in any case.

The error code is propagated back to the ioctl caller so the kernel
warning is causing false alerts.

      net: cxgb3_main: Add CAP_NET_ADMIN check to CHELSIO_GET_MEM · 3546d8f1
      Michael Ellerman authored 
      The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
cxgb_extension_ioctl().

One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
to read memory directly out of the adapter and return it to userspace.
It's not entirely clear what the contents of the adapter memory
contains, but the assumption is that it shouldn't be accessible to all
users.

So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
the is_offload() check, which matches two of the other subcommands in
the same function which also check for is_offload() and CAP_NET_ADMIN.

Found by Ilja by code inspection, not tested as I don't have the
required hardware.
