Use more fields out of the tunnel key (e.g the tunnel source IP address) provided by upper layers for the route lookup done on the encap offload path. Signed-off-by:
-
Or Gerlitz authored
Currently we use subset of the input tunnel key fields (id, ip daddr, dst port) which are provided by upper layers to indentify flows that should go through the same encapsulation and maintain the HW encapsulation table. This is redundant and can get us wrong. Instead, keep a copy of the ip tunnel info provided by the user through TC and have the tunnel key part as the key to our internal hash. Signed-off-by:

Enhance the parsing of offloaded TC rules to set HW matching on outer IPv6 encapsulation headers. This effectively adds support for TC tunnel key release action (decapsulation) of SRIOV offloads over IPv6 tunnels. Signed-off-by:

The current code is allocating the max encap size supported by the firmware and not the size requested by the caller, fix that. Also, spare a warning when the size of the encapsulation headers is bigger from what is supported by the firmware. Signed-off-by:

Add net.ipv4.ip_unprivileged_port_start, which is a per namespace sysctl that denotes the first unprivileged inet port in the namespace. To disable all privileged ports set this to zero. It also checks for overlap with the local port range. The privileged and local range may not overlap. The use case for this change is to allow containerized processes to bind to priviliged ports, but prevent them from ever being allowed to modify their container's network configuration. The latter is accomplished by ensuring that the network namespace is not a child of the user namespace. This modification was needed to allow the container manager to disable a namespace's priviliged port restrictions without exposing control of the network namespace to processes in the user namespace.

Daniel Mack says: ==================== bpf: add longest prefix match map This patch set adds a longest prefix match algorithm that can be used to match IP addresses to a stored set of ranges. It is exposed as a bpf map type. Internally, data is stored in an unbalanced tree of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Note that this has nothing to do with fib or fib6 and is in no way meant to replace or share code with it. It's rather a much simpler implementation that is specifically written with bpf maps in mind. Patch 1/2 adds the implementation, 2/2 an extensive test suite and 3/3 has benchmarking code for the new trie type. Feedback is much appreciated. Changelog: v3 -> v4: * David added a 3rd patch that augments map_perf_test for LPM trie benchmarks * Limit allocation of maps of this new type to CAP_SYS_ADMIN for now, as requested by Alexei * Add a stub .map_delete_elem so the core does not stumble over a NULL pointer when the syscall is invoked * Tests for non-power-of-2 prefix lengths were added * More comment style fixes v2 -> v3: * Store both the key match data and the caller provided value in the same byte array attached to a node. This avoids double allocations * Bring back node->flags to distinguish between 'real' and intermediate nodes * Fix comment style and some typos v1 -> v2: * Turn spin lock into raw spinlock * Lock with irqsave options during trie_update_elem() * Return -ENOMEM properly from trie_alloc() * Force attr->flags == BPF_F_NO_PREALLOC during creation * Set trie->map.pages after creation to account for map memory * Allow arbitrary value sizes * Removed node->flags and denode intermediate nodes through node->value == NULL instead rfc -> v1: * Add __rcu pointer annotations to make sparse happy * Fold _lpm_trie_find_target_node() into its only caller * Fix some minor documentation issues ==================== Signed-off-by: -

Extend the map_perf_test_{user,kern}.c infrastructure to stress test lpm-trie lookups. We hook into the kprobe on sys_gettid() and measure the latency depending on trie size and lookup count. On my Intel Haswell i7-6400U, a single gettid() syscall with an empty bpf program takes roughly 6.5us on my system. Lookups in empty tries take ~1.8us on first try, ~0.9us on retries. Lookups in tries with 8192 entries take ~7.1us (on the first _and_ any subsequent try). Signed-off-by:David Herrmann <dh.herrmann@gmail.com> Reviewed-by:

The first part of this program runs randomized tests against the lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm) based on simple, linear, single linked lists. The implementation should be pretty straightforward. Based on tlpm, this inserts randomized data into bpf-lpm-maps and verifies the trie-based bpf-map implementation behaves the same way as tlpm. The second part uses 'real world' IPv4 and IPv6 addresses and tests the trie with those. Signed-off-by:

This trie implements a longest prefix match algorithm that can be used to match IP addresses to a stored set of ranges. Internally, data is stored in an unbalanced trie of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Tries may be created with prefix lengths that are multiples of 8, in the range from 8 to 2048. The key used for lookup and update operations is a struct bpf_lpm_trie_key, and the value is a uint64_t. The code carries more information about the internal implementation. Signed-off-by:

The EMAC has an internal PHY that is often called the "SGMII". This SGMII is also connected to an external PHY, which is managed by phylib. These dual PHYs often cause confusion. In this case, the data structure for managing the SGMII was mis-named and located in the wrong header file. Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies to the internal PHY only. It also also moved from emac_phy.h (which supports the external PHY) to emac_sgmii.h (where it belongs). To keep the changes minimal, only the structure name is changed, not the names of any variables of that type. Signed-off-by:

Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware is largely based on the full-blown SYSTEMPORT and differs in the following: - no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since we are always interfaced to an Ethernet switch which is fully Ethernet compliant shortcuts could be made - 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt controller bank - slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*) - 256 RX descriptors (512 words) and 256 TX descriptors (not visible) As a consequence of these two things, update the code paths accordingly to differentiate the full-blown from the light version.

Andrew Lunn says: ==================== net: dsa: Move temperature sensor code into PHY. Marvell Ethernet switches contain a temperature sensor. There appears to be one sensor, which is shared by each of the internal PHYs. Each PHY has independent registers to read this sensor, and to set a limit for when an alarm should be raised. Some Marvell discrete PHY also have the same sensor and registers. Moving the HWMON code from DSA into the PHY makes the sensor available in discrete PHYs, and removes the layering violation, the switch driver poking around in PHY registers. While moving the code into the PHY driver, it has been re-written to use the new HWMON APIs. v2: Better Cover note explaining one sensor, but multiple independent registers Simply error checking. ==================== Signed-off-by: -

Saeed Mahameed says: ==================== mlx5 and mlx5e updates 2017-01-19 This series includes some updates for mlx5 core and mlx5e netdevice driver. From Leon, a small fix that remove an unnecessary print. From Eli Cohen, a fix to the FW version printout in case of internal error. From Eugenia Emantayev, two patches, the 1st adds mlx5 1pps (pulse per second) mlx5 infrastructure support and the 2nd adds the necessary bits for mlx5e ptp logic and structures. From Mohamad, add support for s-tagged packet receive when in promiscuous mode. Form Gal Pressman, MCAM (Management capabilities mask register) and PCAM (Ports capabilities mask register) registers infrastructure, those registers are needed in order to query the different statistics registers support in FW, in order for the driver to enable/disable query and reporting them back to user. On top of this infrastructure we've exposed new set of statistics groups: - MPCNT: Physical layer statistical counters (For symbol errors) - PPCNT: PCIe performance counters In addition to the statistics capabilities series we've moved the mlx5 HCA capabilities fields to a dedicated struct under the driver private data. At the end a small patch to update & query statistics in the most desired order. ==================== Signed-off-by: -
