2016-10-27genetlink: statically initialize familiesJohannes Berg8-35/+59
Instead of providing macros/inline functions to initialize the families, make all users initialize them statically and get rid of the macros. This reduces the kernel code size by about 1.6k on x86-64 (with allyesconfig). Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-10-27genetlink: no longer support using static family IDsJohannes Berg8-13/+0
Static family IDs have never really been used, the only use case was the workaround I introduced for those users that assumed their family ID was also their multicast group ID. Additionally, because static family IDs would never be reserved by the generic netlink code, using a relatively low ID would only work for built-in families that can be registered immediately after generic netlink is started, which is basically only the control family (apart from the workaround code, which I also had to add code for so it would reserve those IDs) Thus, anything other than GENL_ID_GENERATE is flawed and luckily not used except in the cases I mentioned. Move those workarounds into a few lines of code, and then get rid of GENL_ID_GENERATE entirely, making it more robust. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

2016-10-26firewire: net: set initial MTU = 1500 unconditionally, fix IPv6 on some ↵Stefan Richter1-7/+1
CardBus cards firewire-net, like the older eth1394 driver, reduced the initial MTU to less than 1500 octets if the local link layer controller's asynchronous packet reception limit was lower. This is bogus, since this reception limit does not have anything to do with the transmission limit. Neither did this reduction affect the TX path positively, nor could it prevent link fragmentation at the RX path. Many FireWire CardBus cards have a max_rec of 9, causing an initial MTU of 1024 - 16 = 1008. RFC 2734 and RFC 3146 allow a minimum max_rec = 8, which would result in an initial MTU of 512 - 16 = 496. On such cards, IPv6 could only be employed if the MTU was manually increased to 1280 or more, i.e. IPv6 would not work without intervention from userland. We now always initialize the MTU to 1500, which is the default according to RFC 2734 and RFC 3146. On a VIA VT6316 based CardBus card which was affected by this, changing the MTU from 1008 to 1500 also increases TX bandwidth by 6 %. RX remains unaffected.

2016-10-26firewire: net: fix maximum possible MTUStefan Richter1-3/+4
Commit b3e3893e1253 ("net: use core MTU range checking in misc drivers") mistakenly introduced an upper limit for firewire-net's MTU based on the local link layer controller's reception capability. Revert this. Neither RFC 2734 nor our implementation impose any particular upper limit. Actually, to be on the safe side and to make the code explicit, set ETH_MAX_MTU = 65535 as upper limit now. (I replaced sizeof(struct rfc2734_header) by the equivalent RFC2374_FRAG_HDR_SIZE in order to avoid distracting long/int conversions.)

2016-10-21hv_netvsc: fix a race between netvsc_send() and netvsc_init_buf()Vitaly Kuznetsov1-0/+7
Fix in commit 880988348270 ("hv_netvsc: set nvdev link after populating chn_table") turns out to be incomplete. A crash in netvsc_get_next_send_section() is observed on mtu change when the device is under load. The race I identified is: if we get to netvsc_send() after we set net_device_ctx->nvdev link in netvsc_device_add() but before we finish netvsc_connect_vsp()->netvsc_init_buf() send_section_map is not allocated and we crash. Unfortunately we can't set net_device_ctx->nvdev link after the netvsc_init_buf() call as during the negotiation we need to receive packets and on the receive path we check for it. It would probably be possible to split nvdev into a pair of nvdev_in and nvdev_out links and check them accordingly in get_outbound_net_device()/ get_inbound_net_device() but this looks like an overkill. Check that send_section_map is allocated in netvsc_send(). Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-10-20net: smc91x: fix neponset breakage by pxa u16 writesRobert Jarzmik1-0/+2
The patch isolating the u16 writes for pxa assumed all machine_is_*() calls were removed, and therefore removed the mach-types.h include which provided them. Unfortunately 2 machine_is_*() remained in smc91x.c file including smc91x.h from which the include was removed, triggering the error: drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_drv_probe’: drivers/net/ethernet/smsc/smc91x.c:2380:2: error: implicit declaration of function ‘machine_is_assabet’ [-Werror=implicit-function-declaration] if (machine_is_assabet() && machine_has_neponset()) This adds back the wrongly removed include.

Writes to u16 has a special handling on 3 PXA platforms, where the hardware wiring forces these writes to be u32 aligned. This patch isolates this handling for PXA platforms as before, but enables this "workaround" to be set up dynamically, which will be the case in device-tree build types. This patch was tested on 2 PXA platforms : mainstone, which relies on the workaround, and lubbock, which doesn't. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: David S.

2016-10-18net: phy: leds: add support for led triggers on phy link state changeZach Brown5-0/+156
Create an option CONFIG_LED_TRIGGER_PHY (default n), which will create a set of led triggers for each instantiated PHY device. There is one LED trigger per link-speed, per-phy. The triggers are registered during phy_attach and unregistered during phy_detach. This allows for a user to configure their system to allow a set of LEDs not controlled by the phy to represent link state changes on the phy. LEDS controlled by the phy are unaffected. For example, we have a board where some of the leds in the RJ45 socket are controlled by the phy, but others are not. Using the triggers provided by this patch the leds not controlled by the phy can be configured to show the current speed of the ethernet connection. The leds controlled by the phy are unaffected.
