2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion4-6/+4
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-09-09vlib: crash in linux_epoll_input_inline for accessing free file index [VPP-1412]Steven1-2/+31
Under rare scenario, epoll may still post an event to VPP although the file descriptor is already deleted via epoll_ctl (EPOLL_CTL_DEL) and the file descriptor is close. VPP tries to access the free file index entry and crash. The fix is to throw away the events which the file descriptor is already deleted.

2018-09-06Fix Telnet option processing issueChris Luke1-1/+8
- A check for the length of the buffer should have used the provided 'len' variable, not 'vec_len' since the buffer pointer may be within a vector, but not the start of one. 'vec_len' reports 0 in that case, causing premature exit from the options processing loop and a wait for further input before it checks the next option. - Also add TCP_NODELAY to CLI sockets to disable Nagle on TCP connections for a possible improvement in interactive response.
