2016-05-02qed: add infrastructure for device self tests.Sudarsana Reddy Kalluru
This patch adds the functionality and APIs needed for selftests. It adds the ability to configure the link-mode which is required for the implementation of loopback tests. It adds the APIs for clock test, register test, interrupt test and memory test.

2016-05-01sctp: signal sk_data_ready earlier on data chunks receptionMarcelo Ricardo Leitner
Dave Miller pointed out that fb586f25300f ("sctp: delay calls to sk_data_ready() as much as possible") may insert latency specially if the receiving application is running on another CPU and that it would be better if we signalled as early as possible. This patch thus basically inverts the logic on fb586f25300f and signals it as early as possible, similar to what we had before.

2016-04-29net/mlx5: Add user chosen levels when allocating flow tablesMaor Gottlieb
Currently, consumers of the flow steering infrastructure can't choose their own flow table levels and are limited to one flow table per level. This just waste levels. Instead, we introduce here the possibility to use multiple flow tables in a level. The user is free to connect these flow tables, while following the rule (FTEs in FT of level x could only point to FTs of level y where y > x). In addition this patch switch the order of the create/destroy flow tables of the NIC(vlan and main).

2016-04-29ppp: add rtnetlink device creation supportGuillaume Nault
Define PPP device handler for use with rtnetlink. The only PPP specific attribute is IFLA_PPP_DEV_FD. It is mandatory and contains the file descriptor of the associated /dev/ppp instance (the file descriptor which would have been used for ioctl(PPPIOCNEWUNIT) in the ioctl-based API). The PPP device is removed when this file descriptor is released (same behaviour as with ioctl based PPP devices). PPP devices created with the rtnetlink API behave like the ones created with ioctl(PPPIOCNEWUNIT). In particular existing ioctls work the same way, no matter how the PPP device was created. The rtnl callbacks are also assigned to ioctl based PPP devices. This way, rtnl messages have the same effect on any PPP devices. The immediate effect is that all PPP devices, even ioctl-based ones, can now be removed with "ip link del". A minor difference still exists between ioctl and rtnl based PPP interfaces: in the device name, the number following the "ppp" prefix corresponds to the PPP unit number for ioctl based devices, while it is just an unrelated incrementing index for rtnl ones.

2016-04-28net: dsa: Provide CPU port statistics to master netdevFlorian Fainelli
This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also include switch-side statistics, which is useful for debugging purposes, when the switch is not properly connected to the Ethernet MAC (duplex mismatch, (RG)MII electrical issues etc.). We accomplish this by retaining the original copy of the master netdev's ethtool_ops, and just overload the 3 operations we care about: get_sset_count, get_strings and get_ethtool_stats so as to intercept these calls and call into the original master_netdev ethtool_ops, plus our own. We take this approach as opposed to providing a set of DSA helper functions that would retrive the CPU port's statistics, because the entire purpose of DSA is to allow unmodified Ethernet MAC drivers to be used as CPU conduit interfaces, therefore, statistics overlay in such drivers would simply not scale. The new ethtool -S <iface> output would therefore look like this now: <iface> statistics p<2 digits cpu port number>_<switch MIB counter names> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2016-04-28tcp: Make use of MSG_EOR in tcp_sendmsgMartin KaFai Lau
This patch adds an eor bit to the TCP_SKB_CB. When MSG_EOR is passed to tcp_sendmsg, the eor bit will be set at the skb containing the last byte of the userland's msg. The eor bit will prevent data from appending to that skb in the future. The change in do_tcp_sendpages is to honor the eor set during the previous tcp_sendmsg(MSG_EOR) call. This patch handles the tcp_sendmsg case. The followup patches will handle other skb coalescing and fragment cases. One potential use case is to use MSG_EOR with SOF_TIMESTAMPING_TX_ACK to get a more accurate TCP ack timestamping on application protocol with multiple outgoing response messages (e.g. HTTP2).

2016-04-28tcp: remove SKBTX_ACK_TSTAMP since it is redundantSoheil Hassas Yeganeh
The SKBTX_ACK_TSTAMP flag is set in skb_shinfo->tx_flags when the timestamp of the TCP acknowledgement should be reported on error queue. Since accessing skb_shinfo is likely to incur a cache-line miss at the time of receiving the ack, the txstamp_ack bit was added in tcp_skb_cb, which is set iff the SKBTX_ACK_TSTAMP flag is set for an skb. This makes SKBTX_ACK_TSTAMP flag redundant. Remove the SKBTX_ACK_TSTAMP and instead use the txstamp_ack bit everywhere. Note that this frees one bit in shinfo->tx_flags.

SOCKWQ_ASYNC_NOSPACE is tested in sock_wake_async() so that a SIGIO signal is sent when needed. tcp_sendmsg() clears the bit. tcp_poll() sets the bit when stream is not writeable. We can avoid two atomic operations by first checking if socket is actually interested in the FASYNC business (most sockets in real applications do not use AIO, but select()/poll()/epoll()) This also removes one cache line miss to access sk->sk_wq->flags in tcp_sendmsg() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2016-04-27net: snmp: kill various STATS_USER() helpersEric Dumazet
In the old days (before linux-3.0), SNMP counters were duplicated, one for user context, and one for BH context. After commit 8f0ea0fe3a03 ("snmp: reduce percpu needs by 50%") we have a single copy, and what really matters is preemption being enabled or disabled, since we use this_cpu_inc() or __this_cpu_inc() respectively. We therefore kill SNMP_INC_STATS_USER(), SNMP_ADD_STATS_USER(), NET_INC_STATS_USER(), NET_ADD_STATS_USER(), SCTP_INC_STATS_USER(), SNMP_INC_STATS64_USER(), SNMP_ADD_STATS64_USER(), TCP_ADD_STATS_USER(), UDP_INC_STATS_USER(), UDP6_INC_STATS_USER(), and XFRM_INC_STATS_USER() Following patches will rename __BH helpers to make clear their usage is not tied to BH being disabled.

2016-04-26devpts: more pty driver interface cleanupsLinus Torvalds
This is more prep-work for the upcoming pty changes. Still just code cleanup with no actual semantic changes. This removes a bunch pointless complexity by just having the slave pty side remember the dentry associated with the devpts slave rather than the inode. That allows us to remove all the "look up the dentry" code for when we want to remove it again. Together with moving the tty pointer from "inode->i_private" to "dentry->d_fsdata" and getting rid of pointless inode locking, this removes about 30 lines of code. Not only is the end result smaller, it's simpler and easier to understand. The old code, for example, depended on the d_find_alias() to not just find the dentry, but also to check that it is still hashed, which in turn validated the tty pointer in the inode. That is a _very_ roundabout way to say "invalidate the cached tty pointer when the dentry is removed". The new code just does dentry->d_fsdata = NULL; in devpts_pty_kill() instead, invalidating the tty pointer rather more directly and obviously. Don't do something complex and subtle when the obvious straightforward approach will do. The rest of the patch (ie apart from code deletion and the above tty pointer clearing) is just switching the calling convention to pass the dentry or file pointer around instead of the inode.

Redesign ethtool statistics handling and reporting in the driver: 1. Move counters to a separate file (en_stats.h). 2. Remove unnecessary dependencies between stats and strings. 3. Use counter descriptors which hold a name and offset for each counter, and will be used to decide which counters will be exposed. For example when adding a new software counter to ethtool, instead of: 1. Add to stats struct. 2. Add to strings struct in the same order. 3. Change macro defining number of software counters. The only thing needed is to link the new counter to a counter descriptor. VPort counters are a set of hardware traffic counters created automatically for each virtual port opened. PPort counters are a set of counters describing per physical port performance statistics. These counters are gathered from hardware register and divided to groups according to different protocols.

I also fix commit 8b32ab9e6ef1: use nla_total_size_64bit() for OVS_FLOW_ATTR_USED in ovs_flow_cmd_msg_size(). Fixes: 8b32ab9e6ef1 ("ovs: use nla_put_u64_64bit()") Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-26sock_diag: align nlattr properly when neededNicolas Dichtel
I also fix the value of INET_DIAG_MAX. It's wrong since commit 8f840e47f190 which is only in net-next right now, thus I didn't make a separate patch.

2016-04-26Revert "ipv6: Revert optional address flusing on ifdown."David S. Miller
This reverts commit 841645b5f2dfceac69b78fcd0c9050868d41ea61. Ok, this puts the feature back. I've decided to apply David A.'s bug fix and run with that rather than make everyone wait another whole release for this feature. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-26ila: add checksum neutral ILA translationsTom Herbert
Support checksum neutral ILA as described in the ILA draft. The low order 16 bits of the identifier are used to contain the checksum adjustment value. The csum-mode parameter is added to described checksum processing. There are three values: - adjust transport checksum (previous behavior) - do checksum neutral mapping - do nothing On output the csum-mode in the ila_params is checked and acted on. If mode is checksum neutral mapping then to mapping and set C-bit. On input, C-bit is checked. If it is set checksum-netural mapping is done (regardless of csum-mode in ila params) and C-bit will be cleared. If it is not set then action in csum-mode is taken.
