--- Comment #7 from Ivan Rozhuk <[email protected]> --- (In reply to Mark Johnston from comment #5) > I don't think m_pullup() is the right layer to handle unmapped mbufs. It > gets called very frequently This is good place to make sure that it handles most all cases where unmapped data can be accessed. Code rely on m_pullup() to ensure that data will be available for read. > The patch to m_pullup() assumes that "m" is mapped, which might not be the > case. May be some additional changes required for this patch :) > e1000 should handle unmapped mbufs though. Do you see "NOMAP" in the > interface flags as reported by ifconfig? Yes, I see NOMAP in ifconfig output. Probably it not work or if_vlan required to be in chain to reproduce error. > I think it wouldn't be too difficult to make bpf_filter() work with unmapped > mbufs. It will fix one error, there is many other netgraph configurations that may be affected. ng_checksum, ng_deflate(?), ng_patch, ng_tcpmss and possible others. -- You are receiving this mail because: You are the assignee for the bug.
