Hi,
|
||||
|
||||
Regression: gdb --pid $(pidof qemu-system-x86_64) stopped working with gdb 7.11.1
|
||||
https://sourceware.org/bugzilla/show_bug.cgi?id=20609
|
||||
|
||||
It was reported for qemu-system-x86_64 but it happens for any multithreaded
|
||||
inferior with a JIT debugging hook.
|
||||
|
||||
136613ef0c6850427317e57be1b644080ff6decb is the first bad commit
|
||||
Author: Pedro Alves <palves@redhat.com>

||||
Fix PR gdb/19828: gdb -p <process from a container>: internal error
|
||||
Message-ID: <cbdf2e04-4fa8-872a-2a23-08c9c1b26e00@redhat.com>

|
||||
|
||||
jit_breakpoint_re_set() is specific by trying to insert a breakpoint into the
|
||||
main executable, not into a shared library. During attachment GDB thinks it
|
||||
needs to use 'breakpoint always-inserted' from
|
||||
breakpoints_should_be_inserted_now() as a newly attached thread is
|
||||
'thread_info->executing' due to 'lwp_info->must_set_ptrace_flags' enabled and
|
||||
the task not yet stopped. This did not happen before the 'bad commit' above
|
||||
which adds tracking of such thread.
|
||||
|
||||
GDB then fails to insert the breakpoints to invalid address as PIE executable
|
||||
gets properly relocated during later phase of attachment. One can see in the
|
||||
backtraces below:
|
||||
#11 in setup_inferior (from_tty=0) at infcmd.c:2663
|
||||
-> jit_breakpoint_re_set_internal()
|
||||
later:
|
||||
#5 in setup_inferior (from_tty=0) at infcmd.c:2673
|
||||
-> svr4_exec_displacement()
|
||||
|
||||
One can suppress the initial breakpoint_re_set() call as there will be another
|
||||
breakpoint_re_set() done from the final post_create_inferior() call in
|
||||
setup_inferior().
|
||||
|
||||
BTW additionally 'threads_executing' cache bool is somehow stale (somewhere is
|
||||
missing update_threads_executing()). I was trying to deal with that in my
|
||||
first/second attempt below but in my final third attempt (attached) I have
|
||||
left it as it is.
|
||||
|
||||
First attempt trying not to falsely require 'breakpoint always-inserted':
|
||||
https://people.redhat.com/jkratoch/rhbz1375553-fix1.patch
|
||||
Reduced first attempt:
|
||||
https://people.redhat.com/jkratoch/rhbz1375553-fix2.patch
|
||||
|
||||
The third attempt suppresses breakpoint insertion until PIE executable gets
|
||||
relocated by svr4_exec_displacement(). Attached.
|
||||
|
||||
No regressions on {x86_64,x86_64-m32,i686}-fedora26pre-linux-gnu.
|
||||
|
||||
OK for check-in for trunk + 7.12?

Sync proc_service definition with GLIBC
|
||||
|
||||
GLIBC BZ#20311 [1] proc_service.h install patch also remove 'const'
|
||||
attributes from ps_get_thread_area and comment #15 discuss why to remove
|
||||
the const attribute (basically since it a callback with the struct
|
||||
ps_prochandle owned by the client it should be able to modify it if
|
||||
it the case).
|
||||
|
||||
On default build this is not the issue and current g++ does not trigger
|
||||
any issue with this mismatch declaration. However, on some bootstrap
|
||||
build configuration where gdbserver is build with gcc instead this
|
||||
triggers:
|
||||
|
||||
error: conflicting types for 'ps_get_thread_area'
|
||||
|
||||
This patch fixes it by syncing the declaration with GLIBC.
