[Qemu-devel] [Bug 1356916] [NEW] Too small argv limit |
Date: |
Thu, 14 Aug 2014 14:31:15 -0000 |
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
Status: New
