2019-07-05net/mlx5e: Add kTLS TX HW offload supportTariq Toukan14-7/+748
Add support for transmit side kernel-TLS acceleration. Offload the crypto encryption to HW. Per TLS connection: - Use a separate TIS to maintain the HW context. - Use a separate encryption key. - Maintain static and progress HW contexts by posting the proper WQEs at creation time, or upon resync. - Use a special DUMP opcode to replay the previous frags and sync the HW context. To make sure the SQ is able to serve an xmit request, increase SQ stop room to cover: - static params WQE, - progress params WQE, and - resync DUMP per frag. Currently supporting TLS 1.2, and key size 128bit. Tested over SimX simulator.

2019-07-05ipv4: Fix NULL pointer dereference in ipv4_neigh_lookup()Ido Schimmel1-1/+1
Both ip_neigh_gw4() and ip_neigh_gw6() can return either a valid pointer or an error pointer, but the code currently checks that the pointer is not NULL. Fix this by checking that the pointer is not an error pointer, as this can result in a NULL pointer dereference [1]. Specifically, I believe that what happened is that ip_neigh_gw4() returned '-EINVAL' (0xffffffffffffffea) to which the offset of 'refcnt' (0x70) was added, which resulted in the address 0x000000000000005a.

2019-07-05net: netsec: Sync dma for device on buffer allocationIlias Apalodimas1-0/+5
Quoting Arnd, We have to do a sync_single_for_device /somewhere/ before the buffer is given to the device. On a non-cache-coherent machine with a write-back cache, there may be dirty cache lines that get written back after the device DMA's data into it (e.g. from a previous memset from before the buffer got freed), so you absolutely need to flush any dirty cache lines on it first. Since the coherency is configurable in this device make sure we cover all configurations by explicitly syncing the allocated buffer for the device before refilling it's descriptors Signed-off-by: Ilias Apalodimas <[email protected]> Signed-off-by: David S.

Ido Schimmel says: ==================== mlxsw: Enable/disable PTP shapers Shalom says: In order to get more accurate hardware time stamping in Spectrum-1, the driver needs to apply a shaper on the port for speeds lower than 40Gbps. This shaper is called a PTP shaper and it is applied on hierarchy 0, which is the port hierarchy. This shaper may affect the shaper rates of all hierarchies. This patchset adds the ability to enable or disable the PTP shaper on the port in two scenarios: 1. When the user wants to enable/disable the hardware time stamping 2. When the port is brought up or down (including port speed change) Patch #1 adds the QEEC.ptps field that is used for enabling or disabling the PTP shaper on a port. Patch #2 adds a note about disabling the PTP shaper when calling to mlxsw_sp_port_ets_maxrate_set(). Patch #3 adds the QPSC register that is responsible for configuring the PTP shaper parameters per speed. Patch #4 sets the PTP shaper parameters during the ptp_init(). Patch #5 adds new operation for getting the port's speed. Patch #6 enables/disables the PTP shaper when turning on or off the hardware time stamping. Patch #7 enables/disables the PTP shaper when the port's status has changed (including port speed change). Patch #8 applies the PTP shaper enable/disable logic by filling the PTP shaper parameters array. ==================== Signed-off-by: David S. Miller <[email protected]>

2019-07-05hsr: implement dellink to clean up resourcesCong Wang5-10/+25
hsr_link_ops implements ->newlink() but not ->dellink(), which leads that resources not released after removing the device, particularly the entries in self_node_db and node_db. So add ->dellink() implementation to replace the priv_destructor. This also makes the code slightly easier to understand.

2019-07-05hsr: fix a memory leak in hsr_del_port()Cong Wang2-2/+5
hsr_del_port() should release all the resources allocated in hsr_add_port(). As a consequence of this change, hsr_for_each_port() is no longer safe to work with hsr_del_port(), switch to list_for_each_entry_safe() as we always hold RTNL lock.

Commit 2589726d12a1 ("bpf: introduce bounded loops") caused a change in the way some registers liveliness is reported in the test_align. Add missing "_w" to a couple of tests.

2019-07-05bpf, riscv: Enable zext optimization for more RV64G ALU opsLuke Nelson1-8/+8
Commit 66d0d5a854a6 ("riscv: bpf: eliminate zero extension code-gen") added the new zero-extension optimization for some BPF ALU operations. Since then, bugs in the JIT that have been fixed in the bpf tree require this optimization to be added to other operations: commit 1e692f09e091 ("bpf, riscv: clear high 32 bits for ALU32 add/sub/neg/lsh/rsh/arsh"), and commit fe121ee531d1 ("bpf, riscv: clear target register high 32-bits for and/or/xor on ALU32"). Now that these have been merged to bpf-next, the zext optimization can be enabled for the fixed operations.
