* target: remove obsolete kernel version switches for 4.19Adrian Schmutzler2020-10-301-61/+0
| | | | | | | This removes unneeded kernel version switches from the targets after kernel 4.19 has been dropped. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* generic: drop outdated kernel version switches in local driversAdrian Schmutzler2020-05-171-14/+2
| | | | | | | This drops the obsolete version switches for non-supported kernels from local drivers in generic target. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* kernel: swconfig: make compatible with kernel 5.2Mathias Kresin2020-02-121-6/+41
| | | | | | | | | | | | | | | | | | | | | Since kernel 5.2 within netlink messages the NLA_F_NESTED nested flag is validated. But swconfig/swlib doesn't set the flag for SWITCH_ATTR_OP_VALUE_PORTS related netlink messages and assigning ports to vlans via swconfig dev switch0 vlan 1 set ports '0 1 2 3 4 6t' Errors put with "Failed to set attribute: Invalid input data or parameter". Relax the validation rules and use the deprecated functions, to use the same level of validation as it was till kernel 5.1. Depending on who has swconfig related netlink messages implemented, there might be more broken tools out there and we should keep backward compatibility if possible.

* kernel: generic: Add kernel 4.14 supportHauke Mehrtens2017-12-161-8/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for kernel 4.14 based on the patches for kernel 4.9. In the configuration I deactivated some of the new possible security features like: CONFIG_REFCOUNT_FULL CONFIG_SLAB_FREELIST_HARDENED CONFIG_SOFTLOCKUP_DETECTOR CONFIG_WARN_ALL_UNSEEDED_RANDOM And these overlay FS options are also deactivated: CONFIG_OVERLAY_FS_INDEX CONFIG_OVERLAY_FS_REDIRECT_DIR I activated this: CONFIG_FORTIFY_SOURCE CONFIG_POSIX_TIMERS CONFIG_SLAB_MERGE_DEFAULT CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED I am not sure if I did the porting correct for the following patches: target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch target/linux/generic/hack-4.14/220-gc_sections.patch target/linux/generic/hack-4.14/321-powerpc_crtsavres_prereq.patch target/linux/generic/pending-4.14/305-mips_module_reloc.patch target/linux/generic/pending-4.14/611-netfilter_match_bypass_default_table.patch target/linux/generic/pending-4.14/680-NET-skip-GRO-for-foreign-MAC-addresses.patch Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

* kernel: require admin permissions for swconfig set operationsFelix Fietkau2016-06-121-0/+3

* 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

* 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
