* kernel: deny swconfig set requests for unprivileged usersJo-Philipp Wich2016-06-111-0/+3
| | | | | | | | | | | | | | | | | The swconfig kernel infrastructure fails to do any permissions checks when changing settings. As such an ordinary user account on a device with a switch can change switch settings without any special permissions. Routers generally have few non-admin users so this isn't a big hole, but it is a security hole. Likely the greatest danger is for multifunction devices which have a lot of extra daemons, compromising a low-security daemon would allow one to modify switch settings and cause the router/switch to appear to lock-up (or cause other sorts of troublesome nyetwork behavior). Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any requests originating from user contexts lacking this capability.

* swconfig: add (PHY) generic helper setting port linkRafał Miłecki2016-02-031-0/+36
| | | | | | | | | | It's quite common for switches to have PHY per port so adding a generic helper setting link state will help many drivers. It just needs an API to access PHYs which this patch also adds. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48621
* swconfig: simplify init codeJonas Gorski2016-01-241-6/+1
| | | | | | | | | Directly return the return value of genl_register_family_with_ops() instead of storing it in a temporary variable, then returning it. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 48472
* swconfig: drop linux < 3.13 code pathsJonas Gorski2016-01-241-20/+0
| | | | | | | | | The oldest kernel we support is 3.18, no need to keep code paths for older kernels. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 48471
* swconfig: add API for setting port link speedRafał Miłecki2016-01-061-1/+48
| | | | | | | | | Some switches can force link speed for a port. Let's add API that will allow drivers to export this feature. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48142
* swconfig: switch kernel PORT_LINK support to SWITCH_TYPE_LINKJohn Crispin2015-12-231-47/+4
| | | | | | | | | As explained earlier, using SWITCH_TYPE_LINK gives more flexibility, it doesn't require e.g. string parsing to read some data. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 47999
* swconfig: add SWITCH_TYPE_LINK and support sending link info to user spaceJohn Crispin2015-12-231-0/+56
| | | | | | | | | | | | | So far we were sending link data as a string. It got some drawbacks: 1) Didn't allow writing clean user space apps reading link state. It was needed to do some screen scraping. 2) Forced whole PORT_LINK communication to be string based. Adding support for *setting* port link required passing string and parting it in the kernel space. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 47997
