[PATCH] drivers/md/dm-ioctl.c::target_message(): don't leak 'argv' mem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If, after allocating memory for 'argv' via dm_split_args(...), we take
the true branch of 'if (!argc)', we'll jump to the 'out:' label and
neglect to free the memory we allocated. We should instead jump to the
'out_argv:' label in that case as far as I can tell.
