* Revert "kernel: ar8327/ar8337: disable ARL access code to avoid lockups ↵Stijn Tintel2017-02-221-6/+0
| | | | | | | | | | | (FS#384)" This reverts commit ec1a695daa7390a6c24e3b28d3956f194cba2cb5. Revert the workaround, the problem was properly fixed in 237454991618e0e8b7ceb8a8a2a43fca12c1a454. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* ar8216: flush ARL table during reset after init_globalsGünther Kelleter2017-02-161-0/+1
| | | | | | | | | | commit 33b72b8e0faf7a39faabece584fd6da61cd8f8df "ar8216: adjust ATU flushing in case of link changes" introduced portwise flushing on link down events. Now the ARL table could be in a chaotic state after boot where ar8xxx_sw_get_arl_table looped forever (depending on the entries collected while booting).

* generic: ar8216: improve ar8xxx_is_possible checkChristian Lamparter2016-10-151-6/+6
| | | | | | | | | | | | | | | | | The commit "generic: ar8216: add sanity check to ar8216_probe" (774da6c7a40320a320b28d71291c0e61fcf7bc8a) stated that PHY IDs should be checked at address 0-4. However, the PHY 4 was never check by the loop. This patch extends the check to be similar to the Atheors SDK. It tries all 4 ports and skips unconnected PHYs if necessary. If it cannot find any familiar PHYs, it will prevent the phy driver from initializing. This patch is necessary for the C-60. It doesn't have a PHY at port 3, so this caused the check in ar8xxx_is_possible to fail. As a result, the ethernet ports on the C-60 didn't work.

* 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.

* AR8216: make ARL age time configurableJohn Crispin2016-03-044-4/+80
| | | | | | | | | | | | | | | | | The default TTL for address resolution table entries is 5 minutes for all members of the AR8216 family. This can cause issues if e.g. Wifi clients roam to another AP and their MAC appears on another switch port suddenly. Then the client may not be reachable until the old ARL entry expires. I would have expected the switch to invalidate old entries if it detects the same MAC on another port. But that's not the case. Therefore make the TTL for ARL entries configurable. The effective TTL will always be a multiple of 7 seconds. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 48913
