Vincent Bernat b5ac1fb271 9p: fix return code of read() when count is 0 ... When reading 0 bytes from an empty file on a 9P filesystem, the return code of read() was not 0 as expected due to an unitialized err variable. Tested with this simple program: #include <assert.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <unistd.h> int main(int argc, const char **argv) { assert(argc == 2); char buffer[256]; int fd = open(argv[1], O_RDONLY|O_NOCTTY); assert(fd >= 0); assert(read(fd, buffer, 0) == 0); return 0; } Signed-off-by: Vincent Bernat <vincent@bernat.im> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>		2015-08-23 14:21:36 -05:00
