pclose(3) is now an alias for fclose(3). We could add a FORTIFY check that you use pclose(3) if and only if you used popen(3), but there seems little value to that when we can just do the right thing. This patch also adds the missing locking to _fwalk --- we need to lock both the global list of FILE*s and also each FILE* we touch. POSIX says that "The popen() function shall ensure that any streams from previous popen() calls that remain open in the parent process are closed in the new child process", which we implement via _fwalk(fclose) in the child, but we might want to just make *all* popen(3) file descriptors O_CLOEXEC in all cases. Ignore fewer errors in popen(3) failure cases. Improve popen(3) test coverage. Bug: http://b/72470344 Test: ran tests Change-Id: Ic937594bf28ec88b375f7e5825b9c05f500af438 |
