abrtd:
instead of
"|/usr/libexec/abrt-ccpp-hook DEBUG_DUMPS_DIR %p %s %u %c",
sets coredump handler to
"|/usr/libexec/abrt-ccpp-hook DEBUG_DUMPS_DIR %s %c %p %u %g %t %h %e OLD_PATTERN"
abrt-ccpp-hook:
expands OLD_PATTERN using values of %s %c %p %u %g %t %h %e
and uses it as a name of "compat coredump".
Patch has a feature which prevents usage of kernel-truncated
OLD_PATTERN: it is passed as hex string *with terminating NUL*
(encoded as 00). If ccpp hook doesn't see 00, it refuses to use
OLD_PATTERN and uses string "core" instead.
Run tested. On a new kernel, passes up to 27 char long old pattern.
Longer patterns are still truncated.
This may be improved in future kernels.
