2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn48-136/+180
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

The IDT ClockMatrix (TM) family includes integrated devices that provide eight PLL channels. Each PLL channel can be independently configured as a frequency synthesizer, jitter attenuator, digitally controlled oscillator (DCO), or a digital phase lock loop (DPLL). Typically these devices are used as timing references and clock sources for PTP applications. This patch adds support for the device.

2019-11-02inet: stop leaking jiffies on the wireEric Dumazet1-1/+1
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

2019-11-02net/mlx5: Support lockless FTE read lookupsParav Pandit2-15/+56
During connection tracking offloads with high number of connections, (40K connections per second), flow table group lock contention is observed. To improve the performance by reducing lock contention, lockless FTE read lookup is performed as described below. Each flow table entry is refcounted. Flow table entry is removed when refcount drops to zero. rhash table allows rcu protected lookup. Each hash table entry insertion and removal is write lock protected. Hence, it is possible to perform lockless lookup in rhash table using following scheme. (a) Guard FTE entry lookup per group using rcu read lock. (b) Before freeing the FTE entry, wait for all readers to finish accessing the FTE. Below example of one reader and write in parallel racing, shows protection in effect with rcu lock. lookup_fte_locked() rcu_read_lock(); search_hash_table() existing_flow_group_write_lock(); tree_put_node(fte) drop_ref_cnt(fte) del_sw_fte(fte) del_hash_table_entry(); call_rcu(); existing_flow_group_write_unlock(); get_ref_cnt(fte) fails rcu_read_unlock(); rcu grace period(); [..] kmem_cache_free(fte); Signed-off-by: Parav Pandit <parav@mellanox.com> Reviewed-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier1-1/+2
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.

Notify the RDMA driver by calling the bnxt_ulp_stop()/bnxt_ulp_start() hooks during error recovery.

2019-11-01bnxt_en: Improve bnxt_ulp_stop()/bnxt_ulp_start() call sequence.Vasundhara Volam3-11/+20
We call bnxt_ulp_stop() to notify the RDMA driver that some error or imminent reset is about to happen. After that we always call some variants of bnxt_close(). In the next patch, we will integrate the recently added error recovery with the RDMA driver. In response to ulp_stop, the RDMA driver may free MSIX vectors and that will also trigger bnxt_close(). To avoid bnxt_close() from being called twice, we set a new flag after ulp_stop is called. If the RDMA driver frees MSIX vectors while the new flag is set, we will not call bnxt_close(), knowing that it will happen in due course. With this change, we must make sure that the bnxt_close() call after ulp_stop will reset IRQ. Modify bnxt_reset_task() accordingly if we call ulp_stop.

2019-11-01bnxt_en: flow_offload: offload tunnel decap rules via indirect callbacksSriharsha Basavapatna3-2/+165
The decap (VXLAN tunnel) flow rules are not getting offloaded with upstream kernel. This is because TC block callback infrastructure has been updated to use indirect callbacks to get offloaded rules from other higher level devices (such as tunnels), instead of ndo_setup_tc(). Since the decap rules are applied to the tunnel devices (e.g, vxlan_sys), the driver should register for indirect TC callback with tunnel devices to get the rules for offloading. This patch updates the driver to register and process indirect TC block callbacks from VXLAN tunnels.

2019-11-01bnxt: Avoid logging an unnecessary message when a flow can't be offloadedSomnath Kotur1-1/+2
For every single case where bnxt_tc_can_offload() can fail, we are logging a user friendly descriptive message anyway, but because of the path it would take in case of failure, another redundant error message would get logged. Just freeing the node and returning from the point of failure should suffice.
