^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There is no bug here, but the code is not perfect either. It copies
sizeof(pkt_dev->/member/) - 1 from user space into buf, and then does
a strcmp(pkt_dev->/member/, buf) hence assuming buf will be null-terminated
and shorter than pkt_dev->/member/ (pkt_dev->/member/ is never
explicitly null-terminated, and strncpy() doesn't have to null-terminate
so the assumption must be on buf). The use of strncpy() without explicit
null-termination looks suspicious. Convert to use straight strcpy().
strncpy() would also null-pad the output, but that's clearly unnecessary
since the author calls memset(pkt_dev->/member/, 0, sizeof(..)); prior
to strncpy(), anyway.
While at it format the code for "dst_min", "dst_max", "src_min" and
"src_max" in the same way by removing extra new lines in one case.

Commit 784abe24c9 ("net: Add decrypted field to skb")
introduced a 'decrypted' field that is explicitly copied on skb
copy and clone.
Move it between headers_start[0] and headers_end[0], so that we
don't need to copy it explicitly as it's copied by the memcpy()
in __copy_skb_header().
While at it, drop the assignment in __skb_clone(), it was
already redundant.
This doesn't change the size of sk_buff or cacheline boundaries.
The 15-bits hole before tc_index becomes a 14-bits hole, and
will be again a 15-bits hole when this change is merged with
commit 8b7008620b ("net: Don't copy pfmemalloc flag in
__copy_skb_header()").
v2: as reported by kbuild test robot (oops, I forgot to build
with CONFIG_TLS_DEVICE it seems), we can't use
CHECK_SKB_FIELD() on a bit-field member. Just drop the
check for the moment being, perhaps we could think of some

mlxsw: Introduce initial Spectrum-2 support
This patch set adds initial support for the Spectrum-2 ASIC. The first
two patches add Spectrum-2 specific KVD linear (KVDL) manager. Unlike
the Spectrum ASIC, there is no linear memory and instead the type of the
entry (e.g., nexthop) and its index are hashed and the entry is placed
in the computed address in the hash-based KVD memory.
The third patch adds Spectrum-2 stubs in the multicast routing code.
Support for multicast routing will be added later on.
Patches 4-15 add ACL support. The Spectrum-2 ASIC includes an
algorithmic TCAM (A-TCAM) and a regular circuit TCAM (C-TCAM) for rules
that can't be inserted into the A-TCAM. This set does not make use of
the A-TCAM and only places rules in the C-TCAM. This provides equivalent
scale and performance to the Spectrum ASIC. A follow-up patch set will
introduce A-TCAM support.
The last patch extends the main driver file to work with both ASICs.

ravb: small sparse fixes
This are fixes that have bugged me whenever I run sparse to check my own
changes to the driver. It's based on the latest net-next tree and tested
on M3-N.

The wrong helper is used to swap the bytes when adding the lower bits of
the TX descriptors tag field in the shared ds_tagl variable. The
variable contains the DS[11:0] field and then the TAG[3:0] bits.
The mistake was highlighted by the sparse warning:
ravb_main.c:1622:31: left side has type restricted __le16
ravb_main.c:1622:31: right side has type unsigned short
ravb_main.c:1622:31: warning: invalid assignment: |=
ravb_main.c:1622:34: warning: cast to restricted __le16
