List-Post: List-Help: List-Subscribe: , List-Archive: (resend after subscribing to list...) Hello, Has anyone gotten nfs-utils to work as a server on a Linux uClibc based system. I'm using Linux 2.4.25 (yup, just built it yesterday) with all the NFS server stuff compiled in (semi-embedded system, no modules). Root and userspace are mostly from the pre-built uClibc development system (http://www.uclibc.org/toolchains.html) - I'm currently using 0.9.23, which is a little old, but I hope that doesn't matter. This is GCC 3.3.1 based. I managed to get nfs-utils (1.0.6) built for this system after hacking up a fake getrpcbynumber_r, which uClibc doesn't have (I called getrpcbynumber and copied the result into the result buffer - yes, I know it's not thread safe, but I don't see how that would be causing my problems). BTW, is getrpcbynumber_r actually documented anywhere - all the man pages I found had the wrong (not enough) parameters - I had to kind of guess what was going on. Anyway I got it running, but what I'm seeing now is while I can export things OK, any mount request for something I've exported are failing. I've debugged mountd, and it looks like all the auth stuff is working. What seems to be failing is a call to nfsctl(NFSCTL_EXPORT, ...). This is the call stack when that happens: ... mount_mnt_3_svc get_rootfh export_export nfsexport nfsctl syscall Everything before the nfsctl/syscall seems to work just fine. get_rootfs does the authentication and that works OK. The syscall however, returns -1, and sets errno to be 22 (EINVAL). I have the system setup if anyone else wants more debugging info. I'll see if I can get a dump of the arguments in nfsctl when it dies. I could even let someone ssh into if they wish. I don't see how uClibc could be causing a problem, but I don't know for sure.
