2020-10-09vlib: save signal handler data to global vblsDave Barach1-4/+4
Turns out that clang is a bit too enthusiastic about mapping static variables to registers, which makes it hard to extract (especially) the faulting VA from an optimized core file. Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I836e5d9695aeb4c5ee4a27f9565acf08ee4eaac0

2020-10-06vppinfra: add heap header in front of dlmalloc spaceDamjan Marion2-12/+1

2020-06-19vlib: add recursive macro expander to debug cliDave Barach1-1/+142
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

2020-06-12vlib: node recyling and node deletion missing triggering graph node syncSteven Luong1-27/+1
When recycling a graph node vnet_register_interface, it is missing an explicit call to vlib_worker_thread_node_runtime_update(). However, there is an implicit call to vlib_worker_thread_node_runtime_update() via vnet_sw_interface_set_flags_helper() if it enables a new feature on the interface for the first time. But that implicit call is not guaranteed. For example, if an interface is created, deleted, and created, then it may skip the implicit call to vlib_worker_thread_node_runtime_update(). When that happens, the graph nodes on thread 0 are not sync'ed to the worker threads. So the worker thread's graph nodes are out of sync momentarily with the main thread's graph nodes until some other event happens which calls for a sync is needed. During this window, the worker thread's graph node is vulnerable and may experience a crash. When deleting a graph node, we never trigger a sync to the worker thread. A patch was committed 3 years ago via https://gerrit.fd.io/r/c/vpp/+/7523 to fix a show run crash. In hindsight, the approach taken by 7523 is not orthogonal. While at it, let's fix it right for both issues with a call to vlib_worker_thread_node_runtime_update() in the appropriate place and remove 7523.

Instead of allocating stack from the main heap, this patch mmaps stack memory together with guard page. This aproach reduces main heap usage, and stack memory is prefaulted on demand, so bigger process stacks will have zero impact on memory usage as long as stack memory is not needed for real. In addition, it fixes issue with systems which have bigger default page size (observed with 65536).
