2018-08-08net/mlx5e: Properly check if hairpin is possible between two functionsOr Gerlitz
The current check relies on function BDF addresses and can get us wrong e.g when two VFs are assigned into a VM and the PCI v-address is set by the hypervisor.

2018-08-08parisc: Define mb() and add memory barriers to assembler unlock sequencesJohn David Anglin
For years I thought all parisc machines executed loads and stores in order. However, Jeff Law recently indicated on gcc-patches that this is not correct. There are various degrees of out-of-order execution all the way back to the PA7xxx processor series (hit-under-miss). The PA8xxx series has full out-of-order execution for both integer operations, and loads and stores. This is described in the following article: http://web.archive.org/web/20040214092531/http://www.cpus.hp.com/technical_references/advperf.shtml For this reason, we need to define mb() and to insert a memory barrier before the store unlocking spinlocks. This ensures that all memory accesses are complete prior to unlocking. The ldcw instruction performs the same function on entry.

2018-08-08parisc: Enable CONFIG_MLONGCALLS by defaultHelge Deller
Enable the -mlong-calls compiler option by default, because otherwise in most cases linking the vmlinux binary fails due to truncations of R_PARISC_PCREL22F relocations. This fixes building the 64-bit defconfig. Cc: stable@vger.kernel.org # 4.0+ Signed-off-by: Helge Deller <deller@gmx.de>

2018-08-08net-next: hinic: fix a problem in free_tx_poll()Zhao Chen
This patch fixes the problem below. The problem can be reproduced by the following steps: 1) Connecting all HiNIC interfaces 2) On server side # sudo ifconfig eth0 192.168.100.1 up #Using MLX CX4 card # iperf -s 3) On client side # sudo ifconfig eth0 192.168.100.2 up #Using our HiNIC card # iperf -c 192.168.101.1 -P 10 -t 100000 after hours of testing, we will see errors: hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 The errors are caused by the following problem. 1) The hinic_get_wqe() checks the "wq->delta" to allocate new WQEs: if (atomic_sub_return(num_wqebbs, &wq->delta) <= 0) { atomic_add(num_wqebbs, &wq->delta); return ERR_PTR(-EBUSY); } If the WQE occupies multiple pages, the shadow WQE will be used. Then the hinic_xmit_frame() fills the WQE. 2) While in parallel with 1), the free_tx_poll() checks the "wq->delta" to free old WQEs: if ((atomic_read(&wq->delta) + num_wqebbs) > wq->q_depth) return ERR_PTR(-EBUSY); There is a probability that the shadow WQE which hinic_xmit_frame() is using will be damaged by copy_wqe_to_shadow(): if (curr_pg != end_pg) { void *shadow_addr = &wq->shadow_wqe[curr_pg * wq->max_wqe_size]; copy_wqe_to_shadow(wq, shadow_addr, num_wqebbs, *cons_idx); return shadow_addr; } This can cause WQE data error and you will see the above error messages.
