From: Wolfram Sang <wsa+rene...@sang-engineering.com> When allocating an skb fails, rxdesc is still NULL (or the previous ring index on further iterations of the loop). However, this pointer is dereferenced after the loop.
This is intended. What we seem to actually need is a NULL check before that dereference.
So, make sure rxdesc is updated immediately at the beginning of the loop.
No, this seems wrong. We don't want an unfilled descriptor to be marked as last, we still need the previous one marked as last. Actually, 'rxdesc' shouldn't be "advanced" even before the second *break* as it is now.
