New: "ls" of an NFSv4 share only works when pumped through strace
https://bugs.busybox.net/show_bug.cgi?id=8941
Bug ID: 8941
Summary: "ls" of an NFSv4 share only works when pumped through
strace
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: major
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: stevejhorton at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
Buildroot = Nightly build commit (46f9454ae177f309c226f4cb8fe7b7f68a109b29) nfs-utils = 1.3.3
busybox = 1.24.1 also tried 1.24.2
Network = 10 Gigabit Ethernet on all hosts
I'm placing the bug here because I can't tell if it's a buildroot or a busybox issue.
NOTES: With a good NFS mount from a buildroot image I can not see the file names unless I use strace like so.
------------------------
# ls -la /share/FILES # I get nothing
# strace -o /dev/null ls -la /share/FILES/ total 44 drwxrwxrwx 4 42949672 42949672 4096 Apr 4 15:58 . drwxrwxrwx 1045 42949672 42949672 32768 May 18 20:03 .. drwxrwxrwx 2 42949672 42949672 4096 May 18 15:05 dir1 drwxrwxrwx 2 42949672 42949672 4096 Apr 4 15:58 dir2

Any Ideas?

Resolution|--- |WONTFIX--- Comment #1 from Thomas Petazzoni <[email protected]> --- Thanks for your bug report, and sorry for the slow response.
Unfortunately, this doesn't really look like a Buildroot problem, but most likely a kernel problem.
Can you test the same kernel, with another distribution (like a Debian distribution) ? Which C library are you using ? If you're using uClibc, can you try glibc ? Is it happening with a different hardware platform, like if you boot the Buildroot system under Qemu ?
We would really need you to investigate further this bug.
Alternatively, you could provide a detailed step-by-step process on how to reproduce the bug: a minimal Buildroot Qemu based defconfig that exhibits the problem, together with the details on how to setup a NFSv4 server. As it is, it's too much effort to setup everything that's needed to reproduce your bug.
