2020-02-24mlxsw: spectrum_trap: Introduce dummy group with thin policerJiri Pirko2-0/+25
For "source traps" it is not possible to change HPKT action to discard. But there is still need to disallow packets arriving to CPU as much as possible. Handle this by introduction of a "dummy group". It has a "thin" policer, which passes as less packets to CPU as possible. The rest is going to be discarded there. The "dummy group" is to be used later on by ACL trap (which is a "source trap").

2020-02-24mlxsw: core: Extend MLXSW_RXL_DIS to register disabled trap groupJiri Pirko3-39/+47
Extend the mlxsw_listener struct to contain trap group for disabled traps too. Rename the original "trap_group" item to "en_trap_group" as it represents enabled state. Let both groups be the same for MLXSW_RXL however extend MLXSW_RXL_DIS to register separate groups for enable and disable.

2020-02-24mlxsw: core: Allow to enable/disable rx_listener for trapJiri Pirko2-10/+40
For source traps, the "thin policer" is going to be used in order to reduce the amount of trapped packets to minimum. However, there will be still small number of packets coming in that need to be dropped in the driver. Allow to enable/disable rx_listener related to specific trap in order to prevent unwanted packets to go up the stack.

2020-02-24floppy: check FDC index for errors before assigning itLinus Torvalds1-2/+5
Jordy Zomer reported a KASAN out-of-bounds read in the floppy driver in wait_til_ready(). Which on the face of it can't happen, since as Willy Tarreau points out, the function does no particular memory access. Except through the FDCS macro, which just indexes a static allocation through teh current fdc, which is always checked against N_FDC. Except the checking happens after we've already assigned the value. The floppy driver is a disgrace (a lot of it going back to my original horrd "design"), and has no real maintainer. Nobody has the hardware, and nobody really cares. But it still gets used in virtual environment because it's one of those things that everybody supports. The whole thing should be re-written, or at least parts of it should be seriously cleaned up. The 'current fdc' index, which is used by the FDCS macro, and which is often shadowed by a local 'fdc' variable, is a prime example of how not to write code. But because nobody has the hardware or the motivation, let's just fix up the immediate problem with a nasty band-aid: test the fdc index before actually assigning it to the static 'fdc' variable.

The patches follow already accepted ethtool change [3] to set as a default linux kernel version. It allows us to remove driver version and present to the users unified picture of driver version, which is similar to default MODULE_VERSION(). As part of this series, I deleted various creative attempts to mark absence of FW. There is no need to set "N/A" in ethtool ->fw_version field and it is enough to do not set it. 1. The code is compile tested and passes 0-day kbuild. 2. The proposed changes are based on commit: 2bb07f4e1d86 ("tc-testing: updated tdc tests for basic filter") 3. WIP branch is [4].

In br_dev_xmit() we perform vlan filtering in br_allowed_ingress() but if the packet has the vlan header inside (e.g. bridge with disabled tx-vlan-offload) then the vlan filtering code will use skb_vlan_untag() to extract the vid before filtering which in turn calls pskb_may_pull() and we may end up with a stale eth pointer. Moreover the cached eth header pointer will generally be wrong after that operation. Remove the eth header caching and just use eth_hdr() directly, the compiler does the right thing and calculates it only once so we don't lose anything.

2020-02-24net: ll_temac: Fix race condition causing TX hangEsben Haabendal1-3/+16
It is possible that the interrupt handler fires and frees up space in the TX ring in between checking for sufficient TX ring space and stopping the TX queue in temac_start_xmit. If this happens, the queue wake from the interrupt handler will occur before the queue is stopped, causing a lost wakeup and the adapter's transmit hanging. To avoid this, after stopping the queue, check again whether there is sufficient space in the TX ring. If so, wake up the queue again. This is a port of the similar fix in axienet driver, commit 7de44285c1f6 ("net: axienet: Fix race condition causing TX hang").

2020-02-24mac80211: Add api to support configuring TID specific configurationTamizh chelvam3-0/+93
Implement drv_set_tid_config api to allow TID specific configuration and drv_reset_tid_config api to reset peer specific TID configuration.

2020-02-24nl80211: modify TID-config APIJohannes Berg5-94/+121
Make some changes to the TID-config API: * use u16 in nl80211 (only, and restrict to using 8 bits for now), to avoid issues in the future if we ever want to use higher TIDs. * reject empty TIDs mask (via netlink policy) * change feature advertising to not use extended feature flags but have own mechanism for this, which simplifies the code * fix all variable names from 'tid' to 'tids' since it's a mask * change to cfg80211_ name prefixes, not ieee80211_ * fix some minor docs/spelling things.
