Subject: [dpdk-stable] [PATCH v2] hash: fix sprintf with snprintf
Date: Thu, 14 Feb 2019 12:57:42 +0000	[thread overview]
Message-ID: <1550149062-14300-1-git-send-email-pallantlax.poornima@intel.com> (raw)
In-Reply-To: <y>

sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used.

Fixes: 473d1bebce ("hash: allow to store data in hash table")
Cc: stable@dpdk.org

Signed-off-by: Pallantla Poornima <pallantlax.poornima@intel.com>

v2: Addressed review comment to correct the format specifier of 
hastest_key_lens.
