2017-06-16networking: convert many more places to skb_put_zero()Johannes Berg21-68/+35
There were many places that my previous spatch didn't find, as pointed out by yuan linyu in various patches. The following spatch found many more and also removes the now unnecessary casts: @@ identifier p, p2; expression len; expression skb; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_zero(skb, len); | -p = (t)skb_put(skb, len); +p = skb_put_zero(skb, len); ) ... when != p ( p2 = (t2)p; -memset(p2, 0, len); | -memset(p, 0, len); ) @@ type t, t2; identifier p, p2; expression skb; @@ t *p; ...

2017-06-16r8152: move calling delay_autosuspend functionhayeswang1-7/+5
Move calling delay_autosuspend() in rtl8152_runtime_suspend(). Calling delay_autosuspend() as late as possible. The original flows are 1. check if the driver/device is busy now. 2. set wake events. 3. enter runtime suspend. If the wake event occurs between (1) and (2), the device may miss it. Besides, to avoid the runtime resume occurs after runtime suspend immediately, move the checking to the end of rtl8152_runtime_suspend().

2017-06-15net/mlx4_en: Refactor mlx4_en_free_tx_descTariq Toukan1-29/+16
Some code re-ordering, functionally equivalent. - The !tx_info->inl check is evaluated anyway in both flows (common case/end case). Run it first, this might finish the flows earlier. - dma_unmap calls are identical in both flows, get it out of the if block into the common area.

2017-06-15net/mlx4_en: Increase default TX ring sizeTariq Toukan1-1/+1
Increase the default TX ring size (from 512 to 1024) to match the RX ring size. This gives the XDP TX ring a better chance to keep up with the rate of its RX ring in case of a high load of XDP_TX actions. Tested: Ethtool counter rx_xdp_tx_full used to increase, after applying this patch it stopped.

2017-06-15net/mlx4_en: Poll XDP TX completion queue in RX NAPITariq Toukan5-16/+51
Instead of having their own NAPIs, XDP TX completion queues get polled within the corresponding RX NAPI. This prevents any possible race on TX ring prod/cons indices, between the context that issues the transmits (RX NAPI) and the context that handles the completions (was previously done in a separate NAPI). This also improves performance, as it decreases the number of NAPIs running on a CPU, saving the overhead of syncing and switching between the contexts.

2017-06-15r8152: add byte_enable for ocp_read_word functionhayeswang1-1/+3
Add byte_enable for ocp_read_word() to replace reading 4 bytes data with reading the desired 2 bytes data. This is used to avoid the issue which is described in commit b4d99def0938 ("r8152: remove sram_read"). The original method always reads 4 bytes data, and it may have problem when reading the PHY registers. The new method is supported since RTL8153B, but it doesn't influence the previous chips. The bits of the byte_enable for the previous chips are the reserved bits, and the hw would ignore them. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

2017-06-15ibmvnic: Remove VNIC_CLOSING check from pending_scrqThomas Falcon1-2/+1
Fix a kernel panic resulting from data access of a NULL pointer during device close. The pending_scrq routine is meant to determine whether there is a valid sub-CRQ message awaiting processing. When the device is closing, however, there is a possibility that NULL messages can be processed because pending_scrq will always return 1 even if there no valid message in the queue. It's not clear what this closing state check was originally meant to accomplish, so just remove it. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.

2017-06-14i40e: Fix a sleep-in-atomic bugJia-Ju Bai1-0/+2
The driver may sleep under a spin lock, and the function call path is: i40e_ndo_set_vf_port_vlan (acquire the lock by spin_lock_bh) i40e_vsi_remove_pvid i40e_vlan_stripping_disable i40e_aq_update_vsi_params i40e_asq_send_command mutex_lock --> may sleep To fixed it, the spin lock is released before "i40e_vsi_remove_pvid", and the lock is acquired again after this function.

If we hit this error path we end up returning ERR_PTR(0) which is NULL. The caller is not expecting that so it results in a NULL dereference.
