Description Frank Ch. Eigler 2010-04-22 23:52:35 UTC
For systemtap/gdb purposes, it would be handy if a user could initiate
automagic download of debuginfo on demand, without having to do
sudo debuginfo-install.  If abrtd is already running, its cache under
/var/cache/abrt-di would be a dandy place to find such goods.

For an unprivileged user to be able to request debuginfo downloading
probably does not represent a great hazard, since that user could
already launch the same program, and interfere with it to cause it
to SEGV, and go to abrtd indirectly that way.

To generate a list of build-ids from coredump or a binary:

$ abrt-action-analyze-core.py -c /bin/bash | tee build_ids
Analyzing coredump '/bin/bash'

To perform the download of debuginfos:

$ abrt-action-install-debuginfo
Coredump references 1 debuginfo files, 1 of them are not installed
Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=updates-released-debug-f15&arch=i386 error was

Noticed that abrt-action-install-debuginfo magically knew to look for file named "build_ids"?

Yes. The reason is that abrt-action-install-debuginfo is suid wrapper binary, therefore it is very paranoid about its params. Even though --help says:

$ abrt-action-install-debuginfo --help
Usage: abrt-action-install-debuginfo.py [-vy] [--ids=BUILD_IDS_FILE]
       [--tmpdir=TMPDIR] [--cache=CACHEDIR] [--size_mb=SIZE]

Installs debuginfos for all build-ids listed in BUILD_IDS_FILE
to CACHEDIR, using TMPDIR as temporary staging area.
Old files in CACHEDIR are deleted until it is smaller than SIZE.

    -v          Be verbose
    -y          Noninteractive, assume 'Yes' to all questions
    --ids       Default: build_ids
    --tmpdir    Default: /tmp/abrt-tmp-debuginfo-RANDOM_SUFFIX
    --cache     Default: /var/cache/abrt-di
    --size_mb   Default: 4096

you can't actually use --ids, --cache or --tmpdir: it won't allow you to pass them to the python wrapper (note abrt-action-install-debuginfo.***PY*** in the help output), to not allow you to access "wrong" files under abrt user it is suid'ed to.

You have to either use abrt-action-install-debuginfo with default params, as I show above, or call wrapped tool, abrt-action-install-debuginfo.py, directly. But then you'll have to specify --cache different from /var/cache/abrt-di - that one isn't writable to normal users.

I am going to improve the wrapper to allow --ids=- (meaning "take stdin").

Comment 3 Bug Zapper 2011-06-02 14:58:28 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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 '13'.

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 13'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 13 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:
