"gdbserver" now supports seamless debugging of processes from containers Prior to this update, when *GDB* was executing inside a Super-Privileged Container (SPC) and attached to a process that was running in another container on Red Hat Enterprise Linux Atomic Host, *GDB* did not locate the binary images of the main executable or any shared libraries loaded by the process to be debugged. As a consequence, *GDB* could have displayed error messages relating to files not being present, or being present but mismatched. Also, *GDB* may have seemed to attach correctly, but subsequent commands may have failed or displayed corrupted information. In Red Hat Enterprise Linux 6.9, "gdbserver" has been extended for seamless support of debugging processes from containers. The Red Hat Enterprise Linux 6.9 version of "gdbserver" newly supports the *qXfer:exec-file:read* and *vFile:setfs* packets. However, the Red Hat Enterprise Linux 6.9 version of "gdb" cannot use these packets. The Red Hat Developer Toolset 4.1 (or later) version of "gdb" is recommended for use with containers and with Red Hat Enterprise Linux 6.9 "gdbserver". The Red Hat Developer Toolset version of "gdbserver" can be used as well. Red Hat Enterprise Linux 6.9 "gdb" can now suggest using "gdbserver" when run with the "-p" parameter (or the "attach" command) and when, at the same time, it detects that the process being attached is from a container. Red Hat Enterprise Linux 6.9 "gdb" now also suggests the explicit use of the "file" command to specify the location of the process executable in the container being debugged. The "file" command does not need to be entered when the Red Hat Developer Toolset version of "gdb" is being used instead. With this update, Red Hat Enterprise Linux 6.9 "gdbserver" provides seamless debugging of processes from containers together with Red Hat Developer Toolset 4.1 (or later) "gdb". Additionally, Red Hat Enterprise Linux 6.9 "gdb" guides the user through the debugging of processes from containers when Red Hat Developer Toolset "gdb" is not available.
