[Qemu-devel] [Bug 1356916] [NEW] Too small argv limit

[Andreas Schwab]

Public bug reported:

Current kernels don't have a fixed argv/environ limit any more, but the
user-space emulation of qemu is still using a fixed limit.  This can
cause execve to fail when it wouldn't on a real system.  For example,
the follwing command should not fail in the emulated environment:

$ /bin/true $(yes | head -n 100000)
-bash: /bin/true: Argument list too long

** Affects: qemu
     Importance: Undecided
