-Empty /proc/self/auxv (linux-user)
-
-The userspace Linux API virtualization used to fake access to /proc/self/auxv, to provide meaningful data for the guest process.
-
-For newer qemu versions, this fails: The openat() is intercepted, but there's no content: /proc/self/auxv has length zero (i.e. reading from it returns 0 bytes).
-
-Good:
-
-$ x86_64-linux-user/qemu-x86_64 /usr/bin/cat /proc/self/auxv | wc -c
-256 /proc/self/auxv
-
-Bad:
-
-$ x86_64-linux-user/qemu-x86_64 /usr/bin/cat /proc/self/auxv | wc -c
-0 /proc/self/auxv
-
-This worked in 2.7.1, and fails in 2.10.1.
-
-This causes e.g. any procps-ng-based tool to segfault while reading from /proc/self/auxv in an endless loop (probably worth another bug report...)
-
-Doing a "git bisect" shows that this commit: https://github.com/qemu/qemu/commit/7c4ee5bcc introduced the problem.
-
-It might be a simple logic (subtraction in the wrong direction?) or sign-ness error: Adding some logging (to v2.10.1)

-And 352 could be the expected length.

-Oops, yes, commit 7c4ee5bcc82e643 broke this -- it switched the order in which we fill in the AUXV info, but forgot to adjust the calculation of the length, which as you've guessed we now get backwards.

-I've just sent this patch which fixes this bug:
-https://lists.gnu.org/archive/html/qemu-devel/2017-11/msg01199.html
-(it turns out it wasn't quite as simple as getting the sign wrong, we were subtracting two things that were totally wrong).
-
-
-Fix has been released with QEMU 2.11:
