Description Yong-Hao Zou 2022-04-19 05:05:46 CEST

Hi,

I got a PANIC in "rte_eal_init"

PANIC in rte_eal_init():
Cannot create pipe

It seems there is a missing check in function "mark_freeable", the result of "rte_mem_virt2memseg" is not checked.

Hi, thank you for reporting an issue.

Please could you explain the condition to reproduce your issue with rte_eal_init?

About "mark_freeable", it is called in "rte_eal_cleanup". Is it related to the issue above?

Hi, I'm sorry that it seems the trace is wrong, it does not relate to the "mark_freeable" function. :(

So please ignore the trace, and is the missing check in "mark_freeable" a bug?

I'm not sure there is a case where rte_mem_virt2memseg can return NULL.
Did you see it happening?
What is the bug you want to fix?

I do not see this happen, just see the code during investigating other issues.

And it seems "rte_mem_virt2memseg" is checked in other functions, so maybe it should be checked in "mark_freeable"?
