Merge branch 'strparser'
Tom Herbert says:
====================
strp: Stream parser for messages
This patch set introduces a utility for parsing application layer
protocol messages in a TCP stream. This is a generalization of the
mechanism implemented of Kernel Connection Multiplexor.
This patch set adapts KCM to use the strparser. We expect that kTLS
can use this mechanism also. RDS would probably be another candidate
to use a common stream parsing mechanism.
The API includes a context structure, a set of callbacks, utility
functions, and a data ready function. The callbacks include
a parse_msg function that is called to perform parsing (e.g.
BPF parsing in case of KCM), and a rcv_msg function that is called
when a full message has been completed.
For strparser we specify the return codes from the parser to allow
the backend to indicate that control of the socket should be
transferred back to userspace to handle some exceptions in the
stream: The return values are:
>0 : indicates length of successfully parsed message
0 : indicates more data must be received to parse the message
-ESTRPIPE : current message should not be processed by the
kernel, return control of the socket to userspace which
can proceed to read the messages itself
other < 0 : Error is parsing, give control back to userspace
assuming that synchronization is lost and the stream
is unrecoverable (application expected to close TCP socket)
There is one issue I haven't been able to fully resolve. If parse_msg
returns ESTRPIPE (wants control back to userspace) the parser may
already have consumed some bytes of the message. There is no way to
put bytes back into the TCP receive queue and tcp_read_sock does not
allow an easy way to peek messages. In lieu of a better solution, we
return ENODATA on the socket to indicate that the data stream is
unrecoverable (application needs to close socket). This condition
should only happen if an application layer message header is split
across two skbuffs and parsing just the first skbuff wasn't sufficient
to determine the that transfer to userspace is needed.
This patch set contains:
- strparser implementation
- changes to kcm to use strparser
- strparser.txt documentation
v2:
- Add copyright notice to C files
- Remove GPL module license from strparser.c
- Add report of rxpause
v3:
- Restore GPL module license
- Use EXPORT_SYMBOL_GPL
v4:
- Removed unused function, changed another to be static as suggested
by davem
- Rewoked data_ready to be called from upper layer, no longer requires
taking over socket data_ready callback as suggested by Lance Chao
Tested:
- Ran a KCM thrash test for 24 hours. No behavioral or performance
differences observed.

strparser: Stream parser for messages
This patch introduces a utility for parsing application layer protocol
messages in a TCP stream. This is a generalization of the mechanism
implemented of Kernel Connection Multiplexor.
The API includes a context structure, a set of callbacks, utility
functions, and a data ready function.
A stream parser instance is defined by a strparse structure that
is bound to a TCP socket. The function to initialize the structure
is:
int strp_init(struct strparser *strp, struct sock *csk,
struct strp_callbacks *cb);
csk is the TCP socket being bound to and cb are the parser callbacks.
The upper layer calls strp_tcp_data_ready when data is ready on the lower
socket for strparser to process. This should be called from a data_ready
callback that is set on the socket:
void strp_tcp_data_ready(struct strparser *strp);
A parser is bound to a TCP socket by setting data_ready function to
strp_tcp_data_ready so that all receive indications on the socket
go through the parser. This is assumes that sk_user_data is set to
the strparser structure.
There are four callbacks.
- parse_msg is called to parse the message (returns length or error).
- rcv_msg is called when a complete message has been received
- read_sock_done is called when data_ready function exits
- abort_parser is called to abort the parser
The input to parse_msg is an skbuff which contains next message under
construction. The backend processing of parse_msg will parse the
application layer protocol headers to determine the length of
the message in the stream. The possible return values are:
>0 : indicates length of successfully parsed message
0 : indicates more data must be received to parse the message
-ESTRPIPE : current message should not be processed by the
kernel, return control of the socket to userspace which
can proceed to read the messages itself
other < 0 : Error is parsing, give control back to userspace
assuming that synchronzation is lost and the stream
is unrecoverable (application expected to close TCP socket)
In the case of error return (< 0) strparse will stop the parser
and report and error to userspace. The application must deal
with the error. To handle the error the strparser is unbound
from the TCP socket. If the error indicates that the stream
TCP socket is at recoverable point (ESTRPIPE) then the application
can read the TCP socket to process the stream. Once the application
has dealt with the exceptions in the stream, it may again bind the
socket to a strparser to continue data operations.
Note that ENODATA may be returned to the application. In this case
parse_msg returned -ESTRPIPE, however strparser was unable to maintain
synchronization of the stream (i.e. some of the message in question
was already read by the parser).
strp_pause and strp_unpause are used to provide flow control. For
instance, if rcv_msg is called but the upper layer can't immediately
consume the message it can hold the message and pause strparser.

The "ugly" part is the action API still accepts list

Intel Wired LAN Driver Updates 2016-08-16
This series contains fixes to e1000e, igb, ixgbe and i40e.
Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation
math in several functions.
Jarod Wilson provides a fix for e1000e which had to broken up into 2
patches, first is prepares the driver for expanding the list of NICs
that have occasional ~10 hour clock jumps when being used for PTP.
Second patch actually fixes i218 silicon which has been experiencing
the clock jumps while using PTP.
Alex provides 2 patches for ixgbe now that he is back at Intel. First
fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches
which resulted in disabling VLAN filtering for all the VFs. Second
corrects the support for disabling the VLAN tag filtering via the
feature bit.
Lastly, David fixes i40e which was causing a kernel panic when
non-contiguous traffic classes or traffic classes not starting with TC0,
were configured on a link partner switch. To fix this, changed the
logic when determining the total number of TCs enabled.

mlxsw: spectrum: Allow packets to be trapped from any PG
When packets enter the device they are classified to a priority group
(PG) buffer based on their PCP value. After their egress port and
traffic class are determined they are moved to the switch's shared
buffer and await transmission, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Packets scheduled to transmission through CPU port (trapped to CPU) use
traffic class 7, which has a zero maximum and minimum quotas. However,
when such packets arrive from PG 0 they are admitted to the shared
buffer as PG 0 has a non-zero minimum quota.
Allow all packets to be trapped to the CPU - regardless of the PG they
were classified to - by assigning a 10KB minimum quota for CPU port and
TC7.

Kernel crash is reported after VF is removed and detached from netvsc
device. Turns out we have multiple different (but related) issues on the
VF removal path which I'm trying to address with PATCHes 2-5 of this
series. PATCH1 is required to support the change.
Changes since v1:
- Re-arrange patches in the series to not introduce new issues [David Miller]
- Add PATCH5 which fixes a new issue I discovered while testing.
- Add Haiyang' A-b tags to PATCH1-4
With regards to Stephen's suggestion: I believe that switching to using RCU

Bonding driver sets IFF_BONDING on both master (the bonding device) and
slave (the real NIC) devices and in netvsc_netdev_event() we want to skip
master devices only. Currently, there is an uncertainty when a slave
interface is removed: if bonding module comes first in netdev_chain it
clears IFF_BONDING flag on the netdev and netvsc_netdev_event() correctly
handles NETDEV_UNREGISTER event, but in case netvsc comes first on the

hv_netvsc: avoid deadlocks between rtnl lock and vf_use_cnt wait
Here is a deadlock scenario:
- netvsc_vf_up() schedules netvsc_notify_peers() work and quits.
- netvsc_vf_down() runs before netvsc_notify_peers() gets executed. As it
is being executed from netdev notifier chain we hold rtnl lock when we
get here.
- we enter while (atomic_read(&net_device_ctx->vf_use_cnt) != 0) loop and
wait till netvsc_notify_peers() drops vf_use_cnt.
- netvsc_notify_peers() starts on some other CPU but netdev_notify_peers()
will hang on rtnl_lock().
- deadlock!
Instead of introducing additional synchronization I suggest we drop
gwrk.dwrk completely and call NETDEV_NOTIFY_PEERS directly. As we're
acting under rtnl lock this is legitimate.

This is achieved by setting the inner_protocol in gre_build_header rather

set when gre_fb_xmit() is used to transmit GRE which was not previously the
case.
I have observed this is not the case when OvS transmits GRE using

pptp: Refactor the struct and macros of PPTP codes
1. Use struct gre_base_hdr directly in pptp_gre_header instead of
duplicated members;
2. Use existing macros like GRE_KEY, GRE_SEQ, and so on instead of
duplicated macros defined by PPTP;
3. Add new macros like GRE_IS_ACK/SEQ and so on instead of
PPTP_GRE_IS_A/S and so on;
