Fix.
Similar fix posted upstream: http://marc.info/?l=linux-kernel&m=120820101915033&w=4 The x86_64 vDSO is used far less than the 32-bit x86 vDSO (it's not necessary for backtraces from syscalls or signals, for example). So I think the only trouble for most users is the pesky message from gdb. If that is enough of a concern, we can put the patch in rawhide/f9. If not, just close as UPSTREAM. (In reply to comment #2) > So I think the only trouble for most users is the pesky message from gdb. It is a message from the so-far Fedora-only build-id files-locating patch. In fact there should be IMO a sanity check in `find-debuginfo.sh' that any .debug file has some `.debug_info' section (at least with just `DW_TAG_compile_unit'). They're still valid if they just have a symtab and no DWARF, technically. And if that's not the case, the file output won't have "not stripped" and so they won't be processed. Still, I think a sanity check of some sort, and even just a warning about no DWARF, might be reasonable. Patch is merged in 2.6.26-rc commit 8705a49c35be088a50b8d5fc5e1aa24d6711fd5b x86 vDSO: compile with -g, 64-bit Do we want this in F9? Yes, it would be nice in F9 just because of that annoying GDB warning, thanks: warning: "/usr/lib/debug/lib/modules/2.6.25-8.fc9.x86_64/vdso/vdso.so.debug": The separate debug info file has no debug info I could patch it in GDB but probably a kernel fix is better. Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is 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 Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
