Bug ID: 18976
Summary: Remote shared library transfer fails when gdbserver
isn't root
Product: gdb
Version: 7.10
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: jmgao at google dot com
Target Milestone: ---
gdbserver's handle_open tries to use multifs_open which on linux, ultimately
attempts to use setns to open files from within the target's mount namespace.
This fails when the user gdbserver is running as doesn't have CAP_SYS_CHROOT
and CAP_SYS_ADMIN, which means the remote file transfer stuff doesn't work on
android.
Submitting a patch to gdb-patches that'll retry with a regular open if the
multifs one fails

gdbserver was actually in a different mount namespace, closing as invalid
