vhost: fix crash when exceeding file descriptors

Protect against DPDK crash when allocation of listen fd >= 1023.
For events on fd:s >1023, the current implementation will trigger
an abort due to access outside of allocated bit mask.

Corrections would include:

  * Match fdset_add() signature in fd_man.c to fd_man.h
  * Handling of return codes from fdset_add()
  * Addition of check of fd number in fdset_add_fd()

The rationale behind the suggested code change is that,
fdset_event_dispatch() could attempt access outside of the FD_SET
bitmask if there is an event on a file descriptor that in turn
looks up a virtio file descriptor with a value > 1023.
Such an attempt will lead to an abort() and a restart of any
vswitch using DPDK.

The root cause is some fields in fm10k_rx_desc are read at the wrong time,
since the descriptor (being 16-bytes big) is not read as a single atomic

in fm10k_rx_desc are read before HW writeback but some fields like DD bit
are read after HW writeback, this will lead to the later packet parsing

8 years agonet/i40e: fix VLAN filtering in promiscuous mode
Jingjing Wu [Thu, 30 Jun 2016 01:25:55 +0000 (09:25 +0800)]
net/i40e: fix VLAN filtering in promiscuous mode

For VLAN filtering, the VLAN table should be enabled.
But the VLAN table is disabled by default until a rule is added.
In promiscuous mode no rule is added to enable the VLAN table.

This patch clears promiscuous VLAN flag on VSI, and adds a
rule to enable the VLAN table to fix VLAN filtering in promiscuous
mode.
