https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293307 Bug ID: 293307 Summary: if_rge detach cleanup for crash when error occurs during attach Product: Base System Version: 14.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: john@cybersashi.com Created attachment 268203 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=268203&action=edit Updated patch for crash As requested in Bug 292879 here's an updated patch for if_rge to avoid crashing in detach if an error occurs while attaching. The additional changes are to avoid calling bus_dmamap_unload if the memory hasn't been allocated and to postpone zeroing q->q_tx / q->q_rx until after the related buffers have been freed. The code to handle an all zeros eaddr is included just because (obviously unrelated to the panic). Tested on a FriendlyElec NanoPC-T6 LTS RK3588 where at the moment rge reset is falling during the attach probably due to recent platform code changes (I'm in the process of bringing up FreeBSD on this platform). -- You are receiving this mail because: You are the assignee for the bug.home | help
