State Changed From-To: open->feedback Need to confirm that this is still an issue. I don't understand the claim, if you use "nfs:phungte2" as your root device then how is the kernel supposed to resolve phungte2 into an IP address? Kris State Changed From-To: feedback->closed We're sorry to not see any feedback received for quite some time. If you think this is still an issue that should be worked on, please provide the requested information and we'll be happy to re-open this ticket. Thank you for bringing this problem to attention! |
depends on the name of the root device, for instance: "nfs:phungte2:/local/diskless_root" the kernel can returns 1 from setrootbyname() in vfs_conf.c or can crash. Fix: in setrootbyname(), the line parsing the name is currently like this: while (cp != '\0' && (*cp < '0' || *cp > '9')) cp++; it should rather be: while (cp != NULL && *cp != 0 || (*cp < '0' || *cp > '9')) cp++; The problem seems to be there still in 4.6.2 in getdiskbyname().
