TOOLS: Fix memory leak after getline() failed This patch fixes buffer freeing in case if getline() failed in function sss_colondb_readline(). ssize_t getline(char **lineptr, size_t *n, FILE *stream); If *lineptr is set to NULL and *n is set 0 before the call, then getline() will allocate a buffer for storing the line. This buffer should be freed by the user program even if getline() failed. man 3 getline This patch fix buffer freeing in case if getline() failed.

TOOLS: Fix minor memory leak in sss_colondb_writeline The variable line was initialized to NULL. The we created temporary context tmp_ctx. We use talloc_asprintf_append to append string to line which is initially NULL and therefore new context which was not connected to tmp_ctx. man 3 talloc_string -> talloc_asprintf_append Reviewed-by: Petr Cech <pcech@redhat.com>
