2018-09-20r8169: fix autoneg issue on resume with RTL8168EHeiner Kallweit1-0/+9
It was reported that chip version 33 (RTL8168E) ends up with 10MBit/Half on a 1GBit link after resuming from S3 (with different link partners). For whatever reason the PHY on this chip doesn't properly start a renegotiation when soft-reset. Explicitly requesting a renegotiation fixes this.

2018-09-20sctp: update dst pmtu with the correct daddrXin Long1-2/+10
When processing pmtu update from an icmp packet, it calls .update_pmtu with sk instead of skb in sctp_transport_update_pmtu. However for sctp, the daddr in the transport might be different from inet_sock->inet_daddr or sk->sk_v6_daddr, which is used to update or create the route cache. The incorrect daddr will cause a different route cache created for the path. So before calling .update_pmtu, inet_sock->inet_daddr/sk->sk_v6_daddr should be updated with the daddr in the transport, and update it back after it's done. The issue has existed since route exceptions introduction. Fixes: 4895c771c7f0 ("ipv4: Add FIB nexthop exceptions.")

MC-aware mode was introduced to mlxsw in commit 7b8195306694 ("mlxsw: spectrum: Configure MC-aware mode on mlxsw ports") and fixed up later in commit 3a3539cd3632 ("mlxsw: spectrum_buffers: Set up a dedicated pool for BUM traffic"). As the final piece of puzzle, a firmware issue whereby a wrong priority was assigned to BUM traffic was corrected in FW version 13.1703.4. Therefore require this FW version in the driver.

2018-09-19qed: Do not add VLAN 0 tag to untagged frames in multi-function mode.Sudarsana Reddy Kalluru2-1/+9
In certain multi-function switch dependent modes, firmware adds vlan tag 0 to the untagged frames. This leads to double tagging for the traffic if the dcbx is enabled, which is not the desired behavior. To avoid this, driver needs to set "dcb_dont_add_vlan0" flag.

2018-09-19qed: Fix populating the invalid stag value in multi function mode.Sudarsana Reddy Kalluru2-1/+18
In multi-function mode, driver receives the stag value (outer vlan) for a PF from management FW (MFW). If the stag value is negotiated prior to the driver load, then the stag is not notified to the driver and hence driver will have the invalid stag value. The fix is to request the MFW for STAG value during the driver load time.

2018-09-18ipv6: fix memory leak on dst->_metricsWei Wang1-1/+4
When dst->_metrics and f6i->fib6_metrics share the same memory, both take reference count on the dst_metrics structure. However, when dst is destroyed, ip6_dst_destroy() only invokes dst_destroy_metrics_generic() which does not take care of READONLY metrics and does not release refcnt. This causes memory leak. Similar to ipv4 logic, the fix is to properly release refcnt and free the memory space pointed by dst->_metrics if refcnt becomes 0.

On the Netgear WNDAP620, the emac ethernet isn't receiving nor xmitting any frames from/to the RTL8363SB (identifies itself as a RTL8367RB). This is caused by the emac hardware not knowing the forced link parameters for speed, duplex, pause, etc. This begs the question, how this was working on the original driver code, when it was necessary to set the phy_address and phy_map to 0xffffffff.

2018-09-18NFC: Fix the number of pipesSuren Baghdasaryan1-1/+1
According to ETSI TS 102 622 specification chapter 4.4 pipe identifier is 7 bits long which allows for 128 unique pipe IDs. Because NFC_HCI_MAX_PIPES is used as the number of pipes supported and not as the max pipe ID, its value should be 128 instead of 127. nfc_hci_recv_from_llc extracts pipe ID from packet header using NFC_HCI_FRAGMENT(0x7F) mask which allows for pipe ID value of 127. Same happens when NCI_HCP_MSG_GET_PIPE() is being used. With pipes array having only 127 elements and pipe ID of 127 the OOB memory access will result.

2018-09-18NFC: Fix possible memory corruption when handling SHDLC I-Frame commandsSuren Baghdasaryan1-0/+10
When handling SHDLC I-Frame commands "pipe" field used for indexing into an array should be checked before usage. If left unchecked it might access memory outside of the array of size NFC_HCI_MAX_PIPES(127). Malformed NFC HCI frames could be injected by a malicious NFC device communicating with the device being attacked (remote attack vector), or even by an attacker with physical access to the I2C bus such that they could influence the data transfers on that bus (local attack vector). skb->data is controlled by the attacker and has only been sanitized in the most trivial ways (CRC check), therefore we can consider the create_info struct and all of its members to tainted. 'create_info->pipe' with max value of 255 (uint8) is used to take an offset of the hdev->pipes array of 127 elements which can lead to OOB write.

DST_NOCOUNT in dst_entry::flags tracks whether the entry counts toward route cache size (net->ipv6.sysctl.ip6_rt_max_size). If the flag is NOT set, dst_ops::pcpuc_entries counter is incremented in dist_init() and decremented in dst_destroy(). This flag is tied to allocation/deallocation of dst_entry and should not be copied from another dst/route. Otherwise it can happen that dst_ops::pcpuc_entries counter grows until no new routes can be allocated because the counter reached ip6_rt_max_size due to DST_NOCOUNT not set and thus no counter decrements on gc-ed routes.

2018-09-17clk: x86: Stop marking clocks as CLK_IS_CRITICALHans de Goede1-7/+0
Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware"), which added the code to mark clocks as CLK_IS_CRITICAL, causes all unclaimed PMC clocks on Cherry Trail devices to be on all the time, resulting on the device not being able to reach S0i3 when suspended. The reason for this commit is that on some Bay Trail / Cherry Trail devices the r8169 ethernet controller uses pmc_plt_clk_4. Now that the clk-pmc-atom driver exports an "ether_clk" alias for pmc_plt_clk_4 and the r8169 driver has been modified to get and enable this clock (if present) the marking of the clocks as CLK_IS_CRITICAL is no longer necessary. This commit removes the CLK_IS_CRITICAL marking, fixing Cherry Trail devices not being able to reach S0i3 greatly decreasing their battery drain when suspended.

The reason for this commit is that on some Bay Trail / Cherry Trail devices the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk" alias, so that the relevant ethernet drivers can try to (optionally) use this, without needing X86 specific code / hacks, thus fixing ethernet on these devices without breaking S0i3 support.

2018-09-17kcm: remove any offset before parsing messagesDominique Martinet1-1/+25
The current code assumes kcm users know they need to look for the strparser offset within their bpf program, which is not documented anywhere and examples laying around do not do. The actual recv function does handle the offset well, so we can create a temporary clone of the skb and pull that one up as required for parsing. The pull itself has a cost if we are pulling beyond the head data, measured to 2-3% latency in a noisy VM with a local client stressing that path. The clone's impact seemed too small to measure. This bug can be exhibited easily by implementing a "trivial" kcm parser taking the first bytes as size, and on the client sending at least two such packets in a single write(). Note that bpf sockmap has the same problem, both for parse and for recv, so it would pulling twice or a real pull within the strparser logic if anyone cares about that.

2018-09-17net/mlx5: Check for SQ and not RQ state when modifying hairpin SQAlaa Hleihel1-1/+1
When modifying hairpin SQ, instead of checking if the next state equals to MLX5_SQC_STATE_RDY, we compare it against the MLX5_RQC_STATE_RDY enum value. The code worked since both of MLX5_RQC_STATE_RDY and MLX5_SQC_STATE_RDY have the same value today. This patch fixes this issue. Fixes: 18e568c390c6 ("net/mlx5: Hairpin pair core object setup") Change-Id: I6758aa7b4bd137966ae28206b70648c5bc223b46 Signed-off-by: Alaa Hleihel <[email protected]> Reviewed-by: Or Gerlitz <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
2018-09-17net/mlx5: Fix read from coherent memoryEli Cohen1-1/+1
Use accessor function READ_ONCE to read from coherent memory modified by the device and read by the driver. This becomes most important in preemptive kernels where cond_resched implementation does not have the side effect which guaranteed the updated value.
