21f82acbb8 ch_ktls/cxgb4: handle partial tag alone SKBs
If TCP congestion caused a very small packets which only has some

such case, so falling back to sw crypto in such cases.

9478e08394 ch_ktls: packet handling prior to start marker
There could be a case where ACK for tls exchanges prior to start
marker is missed out, and by the time tls is offloaded. This pkt

63ee4591fa ch_ktls: Correction in middle record handling
If a record starts in middle, reset TCB UNA so that we could
avoid sending out extra packet which is needed to make it 16
byte aligned to start AES CTR.
Check also considers prev_seq, which should be what is
actually sent, not the skb data length.
Avoid updating partial TAG to HW at any point of time, that's
why we need to check if remaining part is smaller than TAG
size, then reset TX_MAX to be TAG starting sequence number.

687823d2d1 cxgb4/ch_ktls: creating skbs causes panic
Creating SKB per tls record and freeing the original one causes
panic. There will be race if connection reset is requested. By
freeing original skb, refcnt will be decremented and that means,
there is no pending record to send, and so tls_dev_del will be
requested in control path while SKB of related connection is in
queue.
 Better approach is to use same SKB to send one record (partial
data) at a time. We still have to create a new SKB when partial
last part of a record is requested.
 This fix introduces new API cxgb4_write_partial_sgl() to send
partial part of skb. Present cxgb4_write_sgl can only provide
feasibility to start from an offset which limits to header only
and it can write sgls for the whole skb len. But this new API
will help in both. It can start from any offset and can end
writing in middle of the skb.

9d2e5e9eeb cxgb4/ch_ktls: decrypted bit is not enough
If skb has retransmit data starting before start marker, e.g. ccs,
decrypted bit won't be set for that, and if it has some data to
encrypt, then it must be given to crypto ULD. So in place of
decrypted, check if socket is tls offloaded. Also, unless skb has
some data to encrypt, no need to give it for tls offload handling.

c079fe2480 Merge branch 'net-qrtr-add-distant-node-support'
Loic Poulain says:

====================
net: qrtr: Add distant node support

QRTR protocol allows a node to communicate with an other non-immediate
node via an intermdediate immediate node acting as a 'bridge':

node-0 <=> node-1 <=> node-2

This is currently not supported in this upstream version and this
series aim to fix that.

This series is V2 because changes 1, 2 and 3 have already been submitted
separately on LKML.

Changes in v2:
- Add reviewed-by tags from Bjorn and Mani
- Fixing checkpatch issue reported by Jakub

Distant QRTR nodes can be accessed via an other node that acts as
a bridge. When the a QRTR endpoint associated to a bridge node is
released, all the linked distant nodes should also be released.

This patch fixes endpoint release by:
- Submitting QRTR BYE message locally on behalf of all the nodes
accessible through the endpoint.
- Removing all the routable node IDs from radix tree pointing to
the released node endpoint.

====================
net: ipa: little fixes

This series adds a few small fixes to the IPA code.

The first patch appeared in a different form in June, and got some
pushback from David because he felt a problem that can be caught at
build time *should* be caught at build time.
  https://lore.kernel.org/netdev/20200610195332.2612233-1-elder@linaro.org/
I agree with that, but in this case the "problem" was never actually
a problem.  There's a little more explanation on the patch, but
basically now we remove the BUILD_BUG_ON() call entirely.

The second deletes a line of code that isn't needed.

The third converts a warning message to be a debug, as requested by
Stephen Boyd.

And the last one just gets rid of an error message that would be
output after a different message had already reported a problem.

bf795af1d4 net: ipa: drop an error message
There is no need for gsi_modem_channel_halt() to report an error,
because gsi_generic_command() will already have done that if the
command times out.  So get rid of the extra message.

2c642c48b3 net: ipa: change a warning to debug
When we determine from hardware what the size of IPA memory is
we compare it against what we learned about it from DT.

If DT defines a region that's larger than actual memory, we use the
smaller actual size and issue a warning.

If DT defines a smaller region than actual memory we issue a warning
too.  But in this case the difference is harmless; so rather than
issuing a warning, just provide a debug message instead.

Reorder these checks so the one that matters more is done first.

5b8b2262b3 net: ipa: don't break build on large transaction size
The following call in ipa_validate_build() is erroneous:

    BUILD_BUG_ON(sizeof(struct gsi_trans) > 128);

The fact is, it is not a bug for the size of a GSI transaction to be
bigger than 128 bytes.  The correct operation of the driver is not
dependent on the size of this structure.  The only consequence of
the transaction being large is that the amount of memory required
is larger.

The problem this was trying to flag is that a *slight* increase in
the size of this structure will have a disproportionate effect on
the amount of memory used.  E.g. if the structure grew to 132 bytes
the memory requirement for the transaction arrays would be about
double.

With various debugging build flags enabled, the size grows to 160
bytes.  But there's no reason to treat that as a build-time bug.

28b852b1dc openrisc: fix trap for debugger breakpoint signalling
I have been working on getting native Linux GDB support working for the
OpenRISC port.  The trap signal handler here was wrong in a few ways.
During trap handling address (from the EEAR register) is not set by the
CPU, so it is not correct to use here.  We want to use trap as a
break-point so use TRAP_BRKPT.  Adding 4 to the pc was incorrect and
causing GDB to think the breakpoint was not hit.

Fixing these allows GDB to work now.

Jean-Philippe Brucker says:

====================

A few fixes for cross and out-of-tree build of bpftool and runqslower.
These changes allow to build for different target architectures, using
the same source tree.

Since [v2], I addressed Andrii's comments on patches 3 and 5, and added
patch 7 which fixes a build slowdown.

Commit ba2fd563b7 ("tools/bpftool: Support passing BPFTOOL_VERSION to

forcing it to be recomputed on every expansion of CFLAGS and
dramatically slowing down the bpftool build. Restore BPFTOOL_VERSION as
a simply expanded variable, guarded by an ifeq().
