This script pktgen_bench_xmit_mode_netif_receive.sh is a benchmark
script, which can be used for benchmarking part of the network stack.
This can be used for performance improving or catching regression in
that area.
The script is developed for benchmarking ingress qdisc path, original
idea by Alexei Starovoitov. This script don't really need any
hardware. This is achieved via the recently introduced stack inject
feature "xmit_mode netif_receive". See commit 62f64aed62 ("pktgen:
introduce xmit_mode '<start_xmit|netif_receive>'").

Add the pktgen samples script pktgen_sample02_multiqueue.sh that
demonstrates generating packets on multiqueue NICs.
Specifically notice the options "-t" that specifies how many
kernel threads to activate. Also notice the flag QUEUE_MAP_CPU,
which cause the SKB TX queue to be mapped to the CPU running the
kernel thread. For best scalability people are also encourage to
map NIC IRQ /proc/irq/*/smp_affinity to CPU number.
Usage example with "-t" 4 threads and help:
./pktgen_sample02_multiqueue.sh -i eth4 -m 00:1B:21:3C:9D:F8 -t 4

Preparing for removing existing samples/pktgen/ scripts, and
replacing these with easier to use samples.
This commit provides two helper shell files, that can
be "included" by shell source'ing. Namely "functions.sh"
and "parameters.sh".
The parameters.sh file support easy and consistant parameter
parsing across the sample scripts. Usage example is printed on
errors.
The functions.sh file provides, three new shell functions for
configuring the different components of pktgen: pg_ctrl(),
pg_thread() and pg_set(). A slightly improved version of the old
pgset() function is also provided for backwards compat.
The new functions correspond to pktgens different components.
* pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
* pg_thread() control the kernel threads and binding to devices
* pg_set() control setup of individual devices
These changes are borrowed from:

Giving /proc/net/pktgen/pgctrl an invalid command just returns shell
success and prints a warning in dmesg. This is not very useful for
shell scripting, as it can only detect the error by parsing dmesg.
Instead return -EINVAL when the command is unknown, as this provides
userspace shell scripting a way of detecting this.
Also bump version tag to 2.75, because (1) reading /proc/net/pktgen/pgctrl
output this version number which would allow to detect this small
semantic change, and (2) because the pktgen version tag have not been
updated since 2010.

This patch tracks the total number of inbound and outbound segments on a
TCP socket. One may use this number to have an idea on connection
quality when compared against the retransmissions.
RFC4898 named these : tcpEStatsPerfSegsIn and tcpEStatsPerfSegsOut
These are a 32bit field each and can be fetched both from TCP_INFO
getsockopt() if one has a handle on a TCP socket, or from inet_diag
netlink facility (iproute2/ss patch will follow)
Note that tp->segs_out was placed near tp->snd_nxt for good data
locality and minimal performance impact, while tp->segs_in was placed
near tp->bytes_received for the same reason.

Signed-off-by: David S. Miller <davem@davemloft.net>
inet_csk_get_port() randomization effort tends to spread
sockets on all the available range (ip_local_port_range)
This is unfortunate because SO_REUSEADDR sockets have
less requirements than non SO_REUSEADDR ones.
If an application uses SO_REUSEADDR hint, it is to try to
allow source ports being shared.
So instead of picking a random port number in ip_local_port_range,
lets try first in first half of the range.
This gives more chances to use upper half of the range for the
sockets with strong requirements (not using SO_REUSEADDR)
Note this patch does not add a new sysctl, and only changes
the way we try to pick port number.

We currently rely on the setting of SOCK_NOSPACE in the write()
path to ensure that we wake up any epoll edge trigger waiters when
acks return to free space in the write queue. However, if we fail
to allocate even a single skb in the write queue, we could end up
waiting indefinitely.
Fix this by explicitly issuing a wakeup when we detect the condition
of an empty write queue and a return value of -EAGAIN. This allows
userspace to re-try as we expect this to be a temporary failure.
I've tested this approach by artificially making
sk_stream_alloc_skb() return NULL periodically. In that case,
epoll edge trigger waiters will hang indefinitely in epoll_wait()
without this patch.

Add a set_mac_address() NIC-type function for EF10 only, and
use this to set the MAC address on the vadaptor. For Siena and
earlier, the MAC address continues to be set by MC_CMD_SET_MAC;
this is still called on EF10, and including a MAC address in
this command has no effect.
The sriov_mac_address_changed() NIC-type function is no longer
needed on EF10, but it is needed for Siena where it is used to
update the peer address of the PF for VFDI. Change this to use
the new set_mac_address function pointer.
efx_ef10_sriov_mac_address_changed() is no longer called, as VFs
will try to change the MAC address on their vadaptor rather than
trying to change to the context of the PF to alter the vport.
When a VF is running in direct passthrough mode with MAC spoofing
enabled, it will be able to change the MAC address on its vadaptor.
In this case, there is a link to the PF, so find the correct VF in
its ef10_vf array and update the MAC address.
ndo_set_mac_address() can be called during driver unload while
bonding, and in this case the device has already been stopped, so
don't call efx_net_open() to restart it after reconfiguration.
efx->port_enabled is set to false in efx_stop_port(), so it is
indicator of whether the device needs to be restarted.

rocker: transaction fixes
this series addresses what appear to be errors in the handling of
prepare and then commit transactions in the rocker driver.
In all cases the problem is that data structures visible outside of
the transaction are modified during the prepare phase.
In the case of the first two patches this results in the kernel reporting a
BUG. I have noted test-cases in the change logs.
The third patch is also a bug fix, as noted by Toshiaki Makita,
however I have not been able to reliably reproduce the problem and
thus have not provided a test case.
The last patch is a correctness fix that does not fix a bug
that manifests as far as I can tell.
Changes: v3->v4
* All patches
- Add Jiri Pirko's ack
* "rocker: do not make neighbour entry changes when preparing transactions"
- Setting of entry values in all transaction phases
as suggested by Toshiaki Makita
* "rocker: make rocker_port_internal_vlan_id_{get,put}() non-transactional"
- Remove Fixes tag as I believe this is a correctness rather than a bug fix
Changes: v2->v3
* "rocker: do not make neighbour entry changes when preparing transactions"
- Correct inverted logic
- Added ack from Scott Feldman
Changes: v1->v2
* "rocker: do not make neighbour entry changes when preparing transactions"
- Revised changelog to reflect information from Toshiaki Makita
that there is a bug that can manifest
- Update address and ttl regardless of the value of the transaction state

- Added acks from Scott Feldman

The motivation for this is that rocker_port_internal_vlan_id_{get,put} appear
to only partially implement the transaction model: memory allocation
and freeing is transactional, but hash and bitmap manipulation is not.
The latter could be fixed, however, as it is not currently exercised
due to trans always being SWITCHDEV_TRANS_NONE it seems cleaner
to make rocker_port_internal_vlan_id_get non-transactional.
This problem was introduced by c4f20321d9 ("rocker: support
prepare-commit transaction model").
Found by inspection.
I do not believe that this change should have any run-time effect.

rocker_port_ipv4_nh() and in turn rocker_port_ipv4_neigh() may be
be called with trans == SWITCHDEV_TRANS_PREPARE and then
trans == SWITCHDEV_TRANS_COMMIT from switchdev_port_obj_set() via
fib_table_insert().
The first time that rocker_port_ipv4_nh() is called, with
trans == SWITCHDEV_TRANS_PREPARE, _rocker_neigh_add() adds a new entry to
the neigh table.
And the second time rocker_port_ipv4_nh() is called, with
trans == SWITCHDEV_TRANS_COMMIT, that entry is found. This causes
rocker_port_ipv4_nh() to believe it is not adding an entry and thus it
frees "entry", which is still present in rocker driver's neigh table.
This problem does not appear to affect deletion as my analysis is that
deletion is always performed with trans == SWITCHDEV_TRANS_NONE.
For completeness _rocker_neigh_{add,del,prepare} are updated not to
manipulate fib table entries if trans == SWITCHDEV_TRANS_PREPARE.
