2019-02-07Fix parsing overflow in unformat_mac_address_t()Benoît Ganne1-3/+3
'%x' unformat specifier expects a pointer to a 4-byte object and will overflow when using a pointer to a 1-byte object. Use '%X' instead which allows to pass the size of the object alongside its pointer. The bug was exposed with the following commands: ~# make run DBGvpp# loop create loop0 DBGvpp# set ip6 neigh loop0 3001::2 a:a:a:a:a:a DBGvpp# show ip6 neigh Time Address Flags Link layer Interface 35.7743 ::2 D 0a:0a:0a:0a:0a:0a loop0 ^^^ wrong address: should be 3001::2 Note that the bug impact depends from the parsing order and memory layout.

2018-10-12vnet: complete the fix for l3_hdr_offset calculation for single loop ↵Andrew Yourtchenko1-1/+1
fastpass case (VPP-1444) 20e6d36b has moved the calculation of the l3_hdr_offset into the determine_next_node() function, with the assumption that the current_data in the buffer is at the L3 header. This is not the case for the single loop fastpath, where the vlib_buffer_advance() call is made after the call to determine_next_node(), as a day1 behavior. As a result - that path incorrectly sets the l3_hdr_offset. Solution: move the vlib_buffer_advance() call to before determine_next_node() Change-Id: Id5eaa084c43fb6564f8239df4a0b3dc0412b15de Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit 376414f4c3f53af44da4e82ee5d0b1843b291f8e)
2018-10-09vnet: ethernet-input incorrectly sets l3_hdr_offset in some casesAndrew Yourtchenko1-26/+26
The issue surfaced when developing the tap GSO code, with an iteration where output path is reliant on vnet_buffer (b0)->l3_hdr_offset being set correctly in the input path, during performance testing. Adding a workaround in the TX path shows that the issue surfaces only for relatively few packets during the test (about 100 out of 600000). Analysis shows the issue arises if the ethernet-input is handling two untagged packets with different sw_if_index values - then the accelerated path punts to slow path, before the setting of the l2.l2_len values is done, thus resulting in them being 0, and l3_hdr_offset being the same as l2_hdr_offset, wreaking havoc on TX path. The solution is to move the l2_hdr_offset calculation into a place where it is done for all the packets, and move the l3_hdr_offset calculation into the determine_next_node() function - as that function is also the one setting the special-case l2.l2_len value for tagged packets and moving the current_data for the L2 case.

Remove broken special case from l2_input.c:set_int_l2_mode(), which turns out to confuse the graph dispatch engine. The loopback TX function needs to push packets to either ethernet-input or to l2-input, based on bridge / BVI configuration. Rather than overloading a single graph arc - and making vain attempts to reconfigure it - create both arcs and use the correct one. Rewrote the loopback tx function as an idosyncratic multi-arch quad/single loop fn. Change-Id: I15b56ce641d90a11e7b3c7d23859f40e168dd7b2 Signed-off-by: Dave Barach <dave@barachs.net>
