Hi, Would anyone please help with a question on xen-netfront.c code?
In xen-netfront.c, the return value of gnttab_claim_grant_reference() is checked with "BUG_ON((signed short)ref < 0);". Why we use signed short here while the return value is of uint32_t? Am I missing anything or can I send a patch to fix this issue? In xen-blkfront.c and xen-scsifront.c "BUG_ON(gnt_list_entry->gref == -ENOSPC);" is involved to check return value. The guest kernel would panic after grant refs reach a very large number (when guest is attached with large number of devices and live migrated). Thank you very much!
