* genetlink: mark families as __ro_after_initJohannes Berg2016-10-274-6/+6
| | | | | | | | | | | | | | | | Now genl_register_family() is the only thing (other than the users themselves, perhaps, but I didn't find any doing that) writing to the family struct. In all families that I found, genl_register_family() is only called from __init functions (some indirectly, in which case I've add __init annotations to clarifly things), so all can actually be marked __ro_after_init. This protects the data structure from accidental corruption. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* genetlink: statically initialize familiesJohannes Berg2016-10-274-35/+55
| | | | | | | | | | | | 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>
* genetlink: no longer support using static family IDsJohannes Berg2016-10-274-4/+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.

* net: ena: use setup_timer() and mod_timer()Wei Yongjun2016-10-261-6/+3
| | | | | | | | | | | | | | | Use setup_timer() instead of init_timer(), being the preferred/standard way to set a timer up. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer and mod_timer to setup and arm a timer, to make the code cleaner and easier to read. Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: David S.

* hv_netvsc: fix a race between netvsc_send() and netvsc_init_buf()Vitaly Kuznetsov2016-10-211-0/+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>

| | | | | | | | | | | | | | | | | | | | 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.

* net: phy: leds: add support for led triggers on phy link state changeZach Brown2016-10-185-0/+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.
