* MFC revision 1.131Xin LI2006-01-111-5/+5
| | | | | | | | | | | | | 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 <jaro_AT_coop-voz_dot_sk> Reminded by: glebius Notes: svn path=/stable/5/; revision=154226
* MFC 1.62:Gleb Smirnoff2006-01-101-1/+1
| | | | | | | Add \n to log() message. Notes: svn path=/stable/5/; revision=154173
* MFC:Paul Saab2005-05-051-3/+2
| | | | | | | | | | | | | - 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. Notes: svn path=/stable/5/; revision=145924
* MFC:Paul Saab2005-05-051-17/+10

* MFC: rev 1.65Paul Saab2005-04-231-132/+39
| | | | | | | | | | - 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. Notes: svn path=/stable/5/; revision=145463

* MFC: rev 1.165Paul Saab2005-04-231-19/+7
| | | | | | | | Use kern_setitimer() to implement linux_alarm() instead of fondling the real interval timer directly. Notes: svn path=/stable/5/; revision=145451
* MFC:Paul Saab2005-04-211-64/+33
| | | | | | | | | | 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. Notes: svn path=/stable/5/; revision=145381

* Changes to MI Linux emulation code necessary to run 32-bit Linux binariesTim J. Robbins2004-08-1612-112/+244
| | | | | | | | | | | | | | | | | | on AMD64, and the general case where the emulated platform has different size pointers than we use natively: - declare certain structure members as l_uintptr_t and use the new PTRIN and PTROUT macros to convert to and from native pointers. - declare some structures __packed on amd64 when the layout would differ from that used on i386. - include <machine/../linux32/linux.h> instead of <machine/../linux/linux.h> if compiling with COMPAT_LINUX32. This will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel. - other small scattered changes. This should be a no-op on i386 and Alpha.

* Replace linux_getitimer() and linux_setitimer() with implementationsTim J. Robbins2004-08-151-24/+77

* Use sv_psstrings from the current process's sysentvec structure insteadTim J. Robbins2004-08-151-2/+3

* Clean up and wash struct iovec and struct uio handling.Poul-Henning Kamp2004-07-101-20/+7
| | | | | | | | | | | | | | | Add copyiniov() which copies a struct iovec array in from userland into a malloc'ed struct iovec. Caller frees. Change uiofromiov() to malloc the uio (caller frees) and name it copyinuio() which is more appropriate. Add cloneuio() which returns a malloc'ed copy. Caller frees. Use them throughout.

* Deorbit COMPAT_SUNOS.Poul-Henning Kamp2004-06-112-2/+2

* - Replace wait1() with a kern_wait() function that accepts the pid,John Baldwin2004-03-171-32/+15
| | | | | | | | | | | | | | | | | | options, status pointer and rusage pointer as arguments. It is up to the caller to copyout the status and rusage to userland if needed. This lets us axe the 'compat' argument and hide all that functionality in owait(), by the way. This also cleans up some locking in kern_wait() since it no longer has to drop locks around copyout() since all the copyout()'s are deferred. - Convert owait(), wait4(), and the various ABI compat wait() syscalls to use kern_wait() rather than wait1() or wait4(). This removes a bit more stackgap usage. Tested on: i386 Compiled on: i386, alpha, amd64 Notes: svn path=/head/; revision=127140

| | | | | | | | | | | | | | | Remove the unused second argument from udev2dev(). Convert all remaining users of makedev() to use udev2dev(). The semantic difference is that udev2dev() will only locate a pre-existing dev_t, it will not line makedev() create a new one. Apart from the tiny well controlled windown in D_PSEUDO drivers, there should no longer be any "anonymous" dev_t's in the system now, only dev_t's created with make_dev() and make_dev_alias() Notes: svn path=/head/; revision=126081
