Subject: [dpdk-dev] [PATCH 0/5] clean up snprintf use for string copying
Date: Wed,  3 Apr 2019 15:45:00 +0100	[thread overview]
Message-ID: <20190403144505.46234-1-bruce.richardson@intel.com> (raw)

There are quite a few instances remaining in DPDK where snprintf is being
used for string copying. These were not being picked up by our existing
coccinelle script, but that can be fixed by editing the script and running
it against our code. In the process a bug was found and fixed in the
bonding pmd, where we were incorrectly specifiying the buffer length
parameter to snprintf.

The actual replacement was done in two phases - first replacing all
instances where only the snprintf line in question needed changing, then
fixing the other instances where we also needed to add in the header
include. [Using two stages allowed the header addition to be automated too,
since we had a list of files where every one needed the header inclusion]


Bruce Richardson (5):
  net/bonding: fix buffer length when printing strings
  devtools/cocci: make strlcpy replacement smarter
  devtools/cocci: create safer version of strlcpy script
  replace snprintf with strlcpy without adding extra include
  replace snprintf with strlcpy
