#107 pipe10 calls strcmp() on unterminated string

[Nicolas Dade]

ltp/testcases/kernel/syscalls/pipe/pipe10.c writes a string to the child. The length written is strlen(wrbuf), thus it does not include the terminating '\0'. The child read(2)s this into rebuf, and then calls strcmp(rebuf, wrbuf). Since rebuf is not properly terminated strcmp() can fail.

It looks like someone tried to fix this by adding a '\0' at the end of the string used to initialize wrbuf, but since the length sent is determined by strlen(3) that makes no difference.

A simple fix is to include the '\0' in the data written to the child. Patch below.
