[vpp-dev] accessing object pools from multiple threads
Hi , I have a basic question on how object pools are accessed by multiple threads in VPP. Do we have any locks underlying that safe gaurd the object pools ? For example: In acl_main_t, we have a pool of acl lists as below. *acl_list_t *acls; /* Pool of ACLs */* This list will be populated by vpp main_thread for add/del. Also, this list will be accessed by worker thread during packet processing. So, is this list guarded by any lock at lower layers for synchronizing the access between main thread and worker thread ?

Re: [vpp-dev] VAT can support define a macro? #vapi
Macros are currently not supported in .api files.
> define MAX_NUM (12)
The "define" keyword defines API messages, not macros.
The C preprocessor is one possibility to add support for macros,
but not sure whether it would play well with .api syntax.
You can try to add that (or a similar feature) by yourself,
mainly to this [0] directory.

Hi Cipher, Which VPP version are you using? We have found similar issue before and had a patch fixed it in VPP 19.08. https://jira.fd.io/browse/VPP-1680 Thanks, Hongjun From: vpp-dev@lists.fd.io [mailto:vpp-dev@lists.fd.io] On Behalf Of Cipher Chen Sent: Tuesday, September 24, 2019 11:14 AM To: vpp-dev@lists.fd.io Subject: [vpp-dev] #vpp #lb vpp hang and unrecoverable Hi, I found a easy way to get vpp hung.
