2020-08-19vppinfra: minor tweaks for cgo interoperationDave Barach5-13/+67
'type' is a keyword in golang, so s/type/event_type/ in elog.h and elsewhere. Add vec_len_not_inline(...), elog_write_file_not_inline(...) and elog_read_file_not_inline(...) since the inline forms aren't usable. More such tweaks may follow.

2020-07-16vlib: fix asan compilation with gccBenoît Ganne1-0/+12
clang tends to force alignment of all sections when compiling for address sanitizer, confusing VPP plugin infra. On the contrary, GCC does not support this attribute on sections.

2020-06-19vlib: add recursive macro expander to debug cliDave Barach3-33/+92
All of the pieces have been sitting around for years. Added several debug CLI commands: "define <variable-name> <value>" "undefine <variable-name>" "show macro [noeval]" "echo <whatever>" Macros may refer to other macros. To defer evaluation: "define foo \$(bar)" or some such. The macro evaluator is not smart about "define foo \$(foo)" or more complicated circular definitions, so don't do that. Environment variables are available, simply use $<name-of-environment-vbl> The macro expander has a table of (overrideable) builtin names, which are evaluated by calling functions. Simple example: echo $USER define ip1 192.168.1.1/24 define ip2 192.168.2.1/24 loop create loop create set int ip address loop0 $ip1 set int ip address loop1 $ip2 show int addr show macro undefine ip1 undefine ip2 Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I08a800647bac573d8ae3cfd75c40061d41c5f976

2020-05-08vppinfra: set explicit found in search_free_list loopSteven Luong1-2/+6
While https://gerrit.fd.io/r/c/vpp/+/26948 fixed avoid using -1 to index into h->free_lists[b][l] by changing the loop counter, the check for the value of the loop counter (l < 0) cannot be trusted to decide whether we've found a large enough object within the bin or not. When the loop is terminated, the value of the variable l could be ambiguous if it equals to 0 and it is never less than 0, ie, when we bail out of the loop, we don't know if it was due to the breaking out of the condition in if ((s = f_size - size) >= 0) break; or while (l > 0); The fix is to explicitly set a variable when we have found a large enough object inside the loop to be used to test whether the loop was prematurely terminated (found == 1) or the loop just ran exhausted (found == 0) Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0161813fbd44dcba8982a767eac2e0930e9d77e3

Fix the endianness conversion function u32x4_byte_swap() on Arm. Here's an example of using this function with and without the fix. This issue is seen using Mellanox NIC RDMA driver on Arm servers.

2020-05-07vppinfra: loop counter off by 1 in search_free_list()Steven Luong1-1/+1
In search_free_list(), we have this do while loop. do { l--; f_index = h->free_lists[b][l]; f = elt_at (h, f_index); f_size = heap_elt_size (v, f); if ((s = f_size - size) >= 0) break; } while (l >= 0); When (l == 0), we still go back up to execute l--. Then l become -1. The next statement is we index h->free_lists[b][-1]. After that, elt_at() would probably cause a crash in the ASSERT.
