The following reply was made to PR kern/105943; it has been noted by GNATS. From: Yar Tikhiy <yar@comp.chem.msu.su> To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/105943: Network stack may modify read-only mbuf chain copies Date: Sun, 24 Dec 2006 12:14:09 +0300 JFTR: A local workaround was independently applied to if_ethersubr.c in its rev. 1.221. However, less used L2 modules such as arcnet, fddi, and token ring still suffer from the same bug. Moreover, as already noted in this PR, other callers of m_copym() may get it wrong, too. Unfortunately, I neither suffer from this issue personally nor have free time to fully investigate and address it out of general interest. OTOH, financial support can motivate me to do so. Granting the number of source files potentially involved (~45) and the amount of thorough testing requred, it would be not less than 10 hours worth of work. -- Yar
