Subject: [nft PATCH] json: Fix memleak in set_dtype_json()
Date: Thu, 8 Oct 2020 19:10:13 +0200 [thread overview]
Message-ID: <20201008171013.17076-1-phil@nwl.cc> (raw)
Turns out json_string() already dups the input, so the temporary dup
passed to it is lost.
Fixes: e70354f53e9f6 ("libnftables: Implement JSON output support")
Signed-off-by: Phil Sutter <phil@nwl.cc>
