Hello Julia.

I just sent a patch to add yet another string copy mechanism.

This could help avoid misuses of strscpy and strlcpy like this
patch set:

https://lore.kernel.org/lkml/cover.1562283944.git.joe@perches.com/T/

A possible cocci script to do conversions could be:

   $ cat str.cpy.cocci
   @@
   expression e1;
   expression e2;
   @@

   - strscpy(e1, e2, sizeof(e1))
   + stracpy(e1, e2)

   @@
   expression e1;
   expression e2;
   @@

   - strlcpy(e1, e2, sizeof(e1))
   + stracpy(e1, e2)

This obviously does not match the style of all the
scripts/coccinelle cocci files, but this might be
something that could be added improved and added.

This script produces:

$ spatch --in-place -sp-file str.cpy.cocci .
$ git checkout tools/
$ git diff --shortstat
 958 files changed, 2179 insertions(+), 2655 deletions(-)

The remainder of strlcpy and strscpy uses in the
kernel would generally have a form like:

	strlcpy(to, from, DEFINE)

where DEFINE is the specified size of to

Could the cocci script above be updated to find
and correct those styles as well?

cheers, Joe
