From dc32a7c4b2ee873f72b35ad9c7efa7f7c85bb904 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 22 Aug 1999 22:28:03 +0000 Subject: 1999-08-22 Mark Kettenis * hurd/new-fd.c (_hurd_new_fd): Initialize fcntl flags. * hurd/port2fd.c (_hurd_port2fd): Reset the fcntl flags when installing PORT in the descriptor cell. 1999-08-19 Roland McGrath * sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Mark OPTION and TIMEOUT as outputs of the asm to indicate that the signal thread might mutate them. * hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Short circuit to plain mach_msg if only sending or only receiving (i.e., not an RPC). When making an RPC that might get interrupted, save OPTION and the portion of the message buffer that gets clobbered by an EINTR reply message, and properly restore them before attempting to retry the request message send. --- ChangeLog | 18 ++++++++++++++++++ hurd/new-fd.c | 5 ++++- hurd/port2fd.c | 3 ++- 3 files changed, 24 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index 8e2b1827a0..cee4d64461 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,21 @@ +1999-08-22 Mark Kettenis + + * hurd/new-fd.c (_hurd_new_fd): Initialize fcntl flags. + * hurd/port2fd.c (_hurd_port2fd): Reset the fcntl flags when + installing PORT in the descriptor cell. + +1999-08-19 Roland McGrath + + * sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Mark OPTION and + TIMEOUT as outputs of the asm to indicate that the signal thread + might mutate them. + * hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Short circuit to plain + mach_msg if only sending or only receiving (i.e., not an RPC).
