Subject: [PATCH] Fix file descriptor leak when executing CA helpers
|
|
|
77e006 |
|
|
|
77e006 |
cm_cadata_start_generic() creates a pipe. One half is passed
|
|
|
77e006 |
to fetch(), the function that does all helper calls,
|
|
|
77e006 |
via the cm_cadata_state variable ret. The other half is the
|
|
|
77e006 |
reader and is used to detect execution errors. There is a pair
|
|
|
77e006 |
of write/read on this descriptor which on error would be the
|
|
|
77e006 |
errno.
|
|
|
77e006 |
|
|
|
77e006 |
This second half wasn't being closed after reading to test for
|
|
|
77e006 |
errors.
