RTDM drivers refer to open files or sockets by using struct rtdm_fd. Normally, the user-side file descriptors returned by socket() or open() calls are not necessary for driver operations. However, in some special cases the user-side fd has to be determined, for example as return value of rt_tcp_accept() which is a driver function of RTnet's TCP protocol driver.Signed-off-by: Sebastian Smolorz <sebastian.smol...@gmx.de> --- include/cobalt/kernel/rtdm/fd.h | 6 ++++++ kernel/cobalt/rtdm/fd.c | 1 + 2 files changed, 7 insertions(+) diff --git a/include/cobalt/kernel/rtdm/fd.h b/include/cobalt/kernel/rtdm/fd.h index 58d3c4a..572b17e 100644 --- a/include/cobalt/kernel/rtdm/fd.h +++ b/include/cobalt/kernel/rtdm/fd.h @@ -298,6 +298,7 @@ struct rtdm_fd { struct rtdm_fd_ops *ops; struct cobalt_ppd *owner; unsigned int refs; + int ufd; int minor; int oflags; #ifdef CONFIG_XENO_ARCH_SYS3264 @@ -320,6 +321,11 @@ static inline struct cobalt_ppd *rtdm_fd_owner(const struct rtdm_fd *fd) return fd->owner; }+static inline int rtdm_fd_ufd(const struct rtdm_fd *fd)+{ + return fd->ufd; +} + static inline int rtdm_fd_minor(const struct rtdm_fd *fd) { return fd->minor; diff --git a/kernel/cobalt/rtdm/fd.c b/kernel/cobalt/rtdm/fd.c index 8d577b2..807a11e 100644 --- a/kernel/cobalt/rtdm/fd.c +++ b/kernel/cobalt/rtdm/fd.c @@ -166,6 +166,7 @@ int rtdm_fd_enter(struct rtdm_fd *fd, int ufd, unsigned int magic, fd->magic = magic; fd->ops = ops; fd->owner = ppd; + fd->ufd = ufd; fd->refs = 1; set_compat_bit(fd);
