* mlxsw: spectrum_router: Avoid potential packets lossIdo Schimmel2017-03-22
| | | | | | | | | | | | | | | | [ Upstream commit f7df4923fa986247e93ec2cdff5ca168fff14dcf ] When the structure of the LPM tree changes (f.e., due to the addition of a new prefix), we unbind the old tree and then bind the new one. This may result in temporary packet loss. Instead, overwrite the old binding with the new one.

* mlxsw: switchx2: Fix memory leak at skb reallocationArkadi Sharshevsky2017-02-04
| | | | | | | | | | | | | | | | | | | [ Upstream commit 400fc0106dd8c27ed84781c929c1a184785b9c79 ] During transmission the skb is checked for headroom in order to add vendor specific header. In case the skb needs to be re-allocated, skb_realloc_headroom() is called to make a private copy of the original, but doesn't release it. Current code assumes that the original skb is released during reallocation and only releases it at the error path which causes a memory leak. Fix this by adding the original skb release to the main path.

* mlxsw: spectrum_router: Flush FIB tables during finiIdo Schimmel2016-11-14
| | | | | | | | | | | | | | | | | | Since commit b45f64d16d45 ("mlxsw: spectrum_router: Use FIB notifications instead of switchdev calls") we reflect to the device the entire FIB table and not only FIBs that point to netdevs created by the driver. During module removal, FIBs of the second type are removed following NETDEV_UNREGISTER events sent. The other FIBs are still present in both the driver's cache and the device's table. Fix this by iterating over all the FIB tables in the device and flush them. There's no need to take locks, as we're the only writer.

* mlxsw: spectrum_router: Correctly dump neighbour activityArkadi Sharshevsky2016-11-13
| | | | | | | | | | | | | | | | | The device's neighbour table is periodically dumped in order to update the kernel about active neighbours. A single dump session may span multiple queries, until the response carries less records than requested or when a record (can contain up to four neighbour entries) is not full. Current code stops the session when the number of returned records is zero, which can result in infinite loop in case of high packet rate. Fix this by stopping the session according to the above logic.

* mlxsw: spectrum: Fix refcount bug on span entriesYotam Gigi2016-11-13
| | | | | | | | | | | | | | | | | When binding port to a newly created span entry, its refcount is initialized to zero even though it has a bound port. That leads to unexpected behaviour when the user tries to delete that port from the span entry. Fix this by initializing the reference count to 1. Also add a warning to put function.

* mlxsw: spectrum_router: Ignore FIB notification events for non-init namespacesJiri Pirko2016-11-10
| | | | | | | | | | | | | | | | | | | Since now, the table with same id in multiple netnamespaces were squashed to a single virtual router. That is not only incorrect, it also causes error messages when trying to use RALUE register to do double remove of FIB entries, like this one: mlxsw_spectrum 0000:03:00.0: EMAD reg access failed (tid=facb831c00007b20,reg_id=8013(ralue),type=write,status=7(bad parameter)) Since we don't allow ports to change namespaces (NETIF_F_NETNS_LOCAL), and the infrastructure is not yet prepared to handle netnamespaces, just ignore FIB notification events for non-init namespaces. That is clear to do since we don't need to offload them.

* mlxsw: spectrum_router: Fix handling of neighbour structureJiri Pirko2016-11-10
| | | | | | | | | | | | | | | | | | __neigh_create function works in a different way than assumed. It passes "n" as a parameter to ndo_neigh_construct. But this "n" might be destroyed right away before __neigh_create() returns in case there is already another neighbour struct in the hashtable with the same dev and primary key. That is not expected by mlxsw_sp_router_neigh_construct() and the stored "n" points to freed memory, eventually leading to crash. Fix this by doing tight 1:1 coupling between neighbour struct and internal driver neigh_entry. That allows to narrow down the key in internal driver hashtable to do lookups by "n" only.

* mlxsw: spectrum: Fix incorrect reuse of MID entriesIdo Schimmel2016-10-31
| | | | | | | | | | | | | | | | | | | In the device, a MID entry represents a group of local ports, which can later be bound to a MDB entry. The lookup of an existing MID entry is currently done using the provided MC MAC address and VID, from the Linux bridge. However, this can result in an incorrect reuse of the same MID index in different VLAN-unaware bridges (same IP MC group and VID 0). Fix this by performing the lookup based on FID instead of VID, which is unique across different bridges.

| * mlxsw: spectrum: Set port type before setting its addressIdo Schimmel2016-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During port init, we currently set the port's type to Ethernet after setting its MAC address. However, the hardware documentation states this should be the other way around. Align the driver with the hardware documentation and set the port's MAC address after setting its type.

| * mlxsw: spectrum: Don't take multiple references on a FIDIdo Schimmel2016-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 14d39461b3f4 ("mlxsw: spectrum: Use per-FID struct for the VLAN-aware bridge") I added a per-FID struct, which member ports can take a reference on upon VLAN membership configuration. However, sometimes only the VLAN flags (e.g. egress untagged) are toggled without changing the VLAN membership. In these cases we shouldn't take another reference on the FID.

| | | | | | | | | | | | | | | | | | | | | | | | Originally, I expected that there would be needed to call update operation in case RALUE record action is changed. However, that is not needed since write operation takes care of that nicely. Remove prepared construct and always call the write operation.

| * mlxsw: spectrum_router: Fix failure caused by double fib removal from HWJiri Pirko2016-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | In mlxsw we squash tables 254 and 255 together into HW. Kernel adds/dels /32 ip to/from both 254 and 255. On del path, that causes the same prefix being removed twice. Fix this by introducing reference counting for private mlxsw fib entries. That required a bit of code reshuffle. Also put dev into fib entry key so the same prefix could be represented once per every router interface.
