A debugger that is observing _dl_debug_state() would like to see the relocations the same way that any newly-loaded code will see them. The time to call _dl_debug_state() is just before running the initializer functions of the newly-loaded objects. Version-Release number of selected component (if applicable): glibc-2.3.90-30 How reproducible: Always Steps to Reproduce: 1. Look in elf/dl-open.c:158, function dl_open_worker(). 2. 3. Actual Results: The call to _dl_debug_state() is on line 328, the relocations are performed just after that, and the call to _dl_init() is on line 470. Expected Results: The call to _dl_debug_state() should be just before the call to _dl_init(). Additional info: Suggested patch will be attached. --- Additional comment from jreiser(a)bitwagon.com on 2006-01-26 18:41:13 EST --- Created attachment 123756 patch to call _dl_debug_state just before _dl_init in dl_open_worker --- Additional comment from jreiser(a)bitwagon.com on 2006-02-04 17:30:28 EST --- Here is a testcase which shows that gdb runs into trouble when relocations are not performed before ld-linux calls _dl_debug_state() with RT_CONSISTENT. $ cat my_lib.c #include <stdio.h> int sub1(int x) { printf("sub1 %d\n", x); } $ cat my_main.c #include <dlfcn.h> int main() { void *handle = dlopen("./my_lib.so", RTLD_LAZY); void (*sub1)(int) = (void (*)(int))dlsym(handle, "sub1"); sub1(6); return 0; } $ gcc -o my_lib.so -shared -fPIC -g my_lib.c $ gcc -o my_main -g my_main.c -ldl $ gdb my_main GNU gdb Red Hat Linux (6.3.0.0-1.98rh) (gdb) set stop-on-solib-events 1 ## sets a breakpoint on _dl_debug_state() (gdb) run Starting program: /home/jreiser/my_main Reading symbols from shared object read from target memory...done.

If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.)

Full details here: http://sourceware.org/ml/gdb/2008-11/msg00004.html --- Additional comment from jan.kratochvil(a)redhat.com on 2008-11-12 17:38:41 EST --- Created attachment 323394 Minimized to only move _dl_debug_state() after relocations, for glibc-2.8.90-16. (In reply to comment #0) > The time to call _dl_debug_state() is just before running the initializer > functions of the newly-loaded objects. _dl_debug_state() call be probably called at three places: (A) r_map is already correct (guaranteed by RT_CONSISTENT); current version. (B) Like (A) but also after the relocations are resolved. (C) Like (B) but also after the initializers are executed. I believe the call+RT_CONSISTENT was intended for (A) and neither (B) nor (C). (C) is probably too late because we would not be able to debug initializers. But still nobody guarantees we should stop at (B) instead of at current (A). ------------------------------------------------------------------------------ GDB currently assumes that at _dl_debug_state() time if the `nptl_version', `_thread_db_*' and other symbols are present libthread_db can be used. This is currently not true as it fails at least while reading libpthread unrelocated symbol `stack_used': glibc-20081031T2102/nptl/allocatestack.c: static LIST_HEAD (stack_used); File: /lib64/libpthread.so.0 Symbol table '.symtab' contains 907 entries: Num: Value Size Type Bind Vis Ndx Name 61: 0000000000217220 16 OBJECT LOCAL DEFAULT 28 stack_used Relocation section '.rela.dyn' at offset 0x41a8 contains 68 entries: Offset Info Type Sym. Value Sym. Name + Addend 000000217220 000000000008 R_X86_64_RELATIVE 0000000000217220 No other _dl_debug_state() call is done at a later time so the debugger cannot start tracking the threads. The only possibility is to delay libthread_db initialization by placing a breakpoint at the _dl_debug_state() notification time to the function found for DT_INIT. While I implemented the attached GDB patch and so I do not try to avoid this place for the fix I do not find it as the right solution. ------------------------------------------------------------------------------ Another possibility is to fix libpthread data structures to be fully PIC and so understandable by libthread_db at the current _dl_debug_state() point (A). It seems libthread_db can already parse libpthread at (B) time still before its __pthread_initialize_minimal() is called from DT_INIT. I find it also as a real possibility how to fix glibc libthread_db. Still I do not see there a regression risk to delay _dl_debug_state() after relocations resolving; there is nothing more useful on an unrelocated library. (STT_IFUNC code - called code returning a value for relocations - would be a bit harder to debug but only for resolving with RTLD_NOW - not a problem.) Adjusted the patch for glibc-2.8.90-16 making it a minimal working change. --- Additional comment from jan.kratochvil(a)redhat.com on 2008-11-12 17:40:14 EST --- Created attachment 323395 Two testcases (not suitable for the glibc testsuite). Testcase for the problem with libpthread loaded first only on dlopen().

What makes you believe that? I can't find official documentation for RT_CONSISTENT, but Solaris (from which this interface is copied) AFAICT calls _dl_debug_state() (or rather its Solaris equivalent) at (B): http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/sgs/rtld/… --- Additional comment from jan.kratochvil(a)redhat.com on 2008-11-12 18:16:36 EST --- I also could not find any documentation for _dl_debug_state()/RT_CONSISTENT, My text tries to advice (B) as the best choice out of the existing possibilities and thanks to finding out the Solaris code supports that. --- Additional comment from fedora-triage-list(a)redhat.com on 2009-06-09 18:05:58 EDT --- This message is a reminder that Fedora 9 is nearing its end of life.

If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping --- Additional comment from jreiser(a)bitwagon.com on 2010-04-27 11:45:19 EDT --- This bug still is present in Fedora 13, glibc-2.11.90-20; I am changing Version of this bug to 13.
