-Subject: [PATCH] Fix PR gdb/19828: gdb -p <process from a container>: internal
- error
-
-When GDB attaches to a process, it looks at the /proc/PID/task/ dir
-for all clone threads of that process, and attaches to each of them.
-
-Usually, if there is more than one clone thread, it means the program
-is multi threaded and linked with pthreads. Thus when GDB soon after
-attaching finds and loads a libthread_db matching the process, it'll
-add a thread to the thread list for each of the initially found
-lower-level LWPs.
-
-If, however, GDB fails to find/load a matching libthread_db, nothing
-is adding the LWPs to the thread list. And because of that, "detach"
-hits an internal error:
-
- (gdb) PASS: gdb.threads/clone-attach-detach.exp: fg attach 1: attach
- info threads
- Id Target Id Frame
- * 1 LWP 6891 "clone-attach-de" 0x00007f87e5fd0790 in __nanosleep_nocancel () at ../sysdeps/unix/syscall-template.S:84
- (gdb) FAIL: gdb.threads/clone-attach-detach.exp: fg attach 1: info threads shows two LWPs
- detach
- .../src/gdb/thread.c:1010: internal-error: is_executing: Assertion `tp' failed.
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
- Quit this debugging session? (y or n)
- FAIL: gdb.threads/clone-attach-detach.exp: fg attach 1: detach (GDB internal error)

- Cannot find AT_ENTRY auxiliary vector entry.

-
-That's because GDB can't figure out where the scratch pad is.
-
-This is a regression introduced by the earlier changes to make the
-Linux native target always work in non-stop mode.

-This commit makes GDB detect the case and fallback to stepping over
-breakpoints in-line.

-
-
---azLHFNyN32YCQGCU
-Content-Type: text/plain; charset=us-ascii
-Content-Disposition: inline
-
-Hi,
-
-currently
- gdb -p <pid from a container>
-will print:
- warning: Target and debugger are in different PID namespaces; thread lists and other data are likely unreliable
-
-BTW it is a bit lost in all the other messages. Full screen output is in:
- https://sourceware.org/bugzilla/show_bug.cgi?id=19828
-
-It correctly states the problem but it does not say how to solve it.
-
-Is at least this little suggestion OK?
-
-Originally I wanted to suggest also the Docker "-p 1234:1234" parameter but
-I see the containers are more general topic than just Docker (even LxC etc.).
-
-According to Gary future GDBs should be able to work even without gdbserver.
-But currently gdbserver is still required.
-
-
-Thanks,
-Jan

- 33b4777ca1b7 btrace, frame: fix crash in get_frame_type
- a038fa3e14a4 stack: check frame_unwind_caller_id
- 2f3ef606b912 frame: add skip_tailcall_frames
-
- In skip_artificial_frames we repeatedly call get_prev_frame_always until we get
- a non-inline and non-tailcall frame assuming that there must be such a frame
- eventually.
-
- For record targets, however, we may have a frame chain that consists only of
- artificial frames. This leads to a crash in get_frame_type when dereferencing a
- NULL frame pointer.
-
- Change skip_artificial_frames and skip_tailcall_frames to return NULL in such a
- case and modify each caller to cope with a NULL return.
-
- In frame_unwind_caller_pc and frame_unwind_caller_arch, we simply assert that
- the returned value is not NULL. Their caller was supposed to check
- frame_unwind_caller_id before calling those functions.
-
- In other cases, we thrown an error.
-
- In infcmd further move the skip_tailcall_frames call to the forward-stepping
- case since we don't need a frame for reverse execution and we don't want to fail
- because of that. Reverse-finish does make sense for a tailcall frame.

- Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach
-
- Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html
-
- GDB currently fails to fetch the list of already-registered JIT
- modules on attach.
-
- Nothing is calling jit_inferior_init, which is what is responsible for
- walking the JIT object list at init time.
-
- Despite the misleading naming, jit_inferior_created_hook ->
- jit_inferior_init is only called when the inferior execs.
-
- This regressed with the fix for PR gdb/13431 (03bef283c2d3):
- https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
- removed the inferior_created (jit_inferior_created_observer)
- observer.
-
- Adding an inferior_created observer back fixes the issue.
-
- In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
- which is returning the wrong result when we already have the
- breakpoint at the right address.
-
- gdb/ChangeLog:
- 2016-03-31 Yichao Yu <yyc1992@gmail.com>
-
- PR gdb/19858
- * jit.c (jit_breakpoint_re_set_internal): Return 0 if we already
- got the breakpoint at the right address.
- (jit_inferior_created): New function.
- (_initialize_jit): Install jit_inferior_created as
- inferior_created observer.

- Add regression test for PR gdb/19858 (JIT code registration on attach)
-
- The compiled code's .debug_line is wrong (for the simplistic approach of GDB
- to put a breakpoint on the first address belonging to that source line) and so
- GDB misses the breakpoint at the last line:
- WAIT_FOR_GDB; return 0; /* gdb break here 2 */
-
- Most of the patch is just about reindentation, no changes there.

- Fix PR remote/19840: gdb crashes on reverse-stepi
-
- Reverse debugging against a remote target that does reverse debugging
- itself (with the bs/bc packets) always trips on:
-
- (gdb) target remote localhost:...
- (gdb) reverse-stepi
- ../../gdb/target.c:602: internal-error: default_execution_direction: to_execution_direction must be implemented for reverse async
-
- I missed adding a to_execution_direction method to remote.c in commit
- 3223143295b5 (Adds target_execution_direction to make record targets
- support async mode), GDB 7.4 time. Later, GDB 7.8 switched to
- target-async on by default, making the regression user-visible by
- default too.
-
- Fix is simply to add the missing to_execution_direction implementation
- to target remote.
-
- Tested by Andi Kleen against Simics.

- Workaround gdbserver<7.7 for setfs
-
- With current FSF GDB HEAD and old FSF gdbserver I expected I could do:
- gdb -ex 'file target:/root/redhat/threadit' -ex 'target remote :1234'
- (supplying that unsupported qXfer:exec-file:read by "file")
- But that does not work because:
- Sending packet: $vFile:setfs:0#bf...Packet received: OK
- Packet vFile:setfs (hostio-setfs) is supported
- ...
- Sending packet: $vFile:setfs:104#24...Packet received: OK
- "target:/root/redhat/threadit": could not open as an executable file: Invalid argument
-
- GDB documentation says:
- The valid responses to Host I/O packets are:
- An empty response indicates that this operation is not recognized.
-
- This "empty response" vs. "OK" was a bug in gdbserver < 7.7. It was fixed by:
- commit e7f0d979dd5cc4f8b658df892e93db69d6d660b7
