Michal, thanks for fixing this. Reviewed-by: Boris Fiuczynski <fiuczy@xxxxxxxxxxxxx> On 2/26/24 13:22, Michal Privoznik wrote:
There are two memleaks inside of nodedevmdevctltest: 1) In the testCommandDryRunCallback() - when appending lines to stdinbuf the pointer is overwritten without freeing the old memory it pointed to. 2) In testMdevctlModify() the livecmd variable is reused and since its marked as g_autoptr() the first use leaks.
