date: 2005/12/13 15:32:52; author: delphij; state: Exp; lines: +5 -5 In Linux, kernel parameters passed to ioctl are by value, while in FreeBSD they are passed by reference. Handle the difference within the linux_ioctl_termio on the LINUX_TCFLSH path. Submitted by: Jaroslav Drzik Reminded by: glebius

MFC 1.62:

Add \n to log() message.

- Tweak kern_msgctl() to return a copy of the requested message queue id structure in the struct pointed to by the 3rd argument for IPC_STAT and get rid of the 4th argument. The old way returned a pointer into the kernel array that the calling function would then access afterwards without holding the appropriate locks and doing non-lock-safe things like copyout() with the data anyways. This change removes that unsafeness and resulting race conditions as well as simplifying the interface.

Split out kernel side of msgctl(2) into two parts.

MFC: rev 1.65

2005-04-23T21:57:43Z

- Use kern_{l,f,}stat() and kern_{f,}statfs() functions rather than duplicating the contents of the same functions inline. - Consolidate common code to convert a BSD statfs struct to a Linux struct into a static worker function.

MFC: rev 1.28

2005-04-23T21:56:04Z

Make linux_emul_convpath() a simple wrapper for kern_alternate_path().

MFC: rev 1.165

2005-04-23T16:38:27Z

Use kern_setitimer() to implement linux_alarm() instead of fondling the real interval timer directly.

MFC:

2005-04-21T22:00:10Z

Split out kernel side of {get,set}itimer(2) into two parts: the first that pops data from the userland and pushes results back and the second which does actual processing. Use the latter to eliminate stackgap in the linux wrappers of those syscalls.

MFC: Handle unimplemented syscall by instantly returning ENOSYS instead of sending

signal first and only then returning ENOSYS to match what real linux does. Approved by: re (kensmith)

MFC: semctl(2) with IPC_STAT command should return zero in case of success.
