Subject: [PATCH] Don't close STDERR when submitting request
|
|
|
5e5f7c |
|
|
|
5e5f7c |
cm_subproc_mark_most_cloexec() now closes all open file
|
|
|
5e5f7c |
descriptors except for up to three requested for stdin, stdout
|
|
|
5e5f7c |
and stderr. Before the optimization those three were always
|
|
|
5e5f7c |
left open.
|
|
|
5e5f7c |
|
|
|
5e5f7c |
This was causing errors in the IPA helper ipa-server-guard
|
|
|
5e5f7c |
because it tries to display the contents of stderr which was
|
|
|
5e5f7c |
always being closed, causing ipa-server-guard to blow up.
