* MFC r283427:dchagin2016-01-091-2/+2
| | | | | Where possible we will use M_LINUX malloc(9) type. Move M_FUTEX defines to the linux_common.ko.
* MFC r276564, r276654:dchagin2015-01-111-3/+3
| | | | | | | | | | | | | | | | Cast *path to silence clang -Wpointer-sign warning. Indeed, instead of hiding the kern___getcwd() bug by bogus cast in r276564, change path type to char * (pathnames are always char *). And remove bogus casts of malloc(). kern___getcwd() internally doesn't actually use or support u_char * paths, except to copy them to a normal char * path. These changes are not visible to libc as libc/gen/getcwd.c misdeclares __getcwd() as taking a plain char * path. While here remove _SYS_SYSPROTO_H_ for __getcwd() syscall as we always have sysproto.h.

* vn_lock() is currently only used with the 'curthread' passed as argument.attilio2008-01-101-2/+2
| | | | | | | | | | | | | | | | Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed. Manpage and FreeBSD_version will be updated through further commits. As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

* Merge first in a series of TrustedBSD MAC Framework KPI changesrwatson2007-10-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | from Mac OS X Leopard--rationalize naming for entry points to the following general forms: mac_<object>_<method/action> mac_<object>_check_<method/action> The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names. All MAC policy modules will need to be recompiled, and modules not updates as part of this commit will need to be modified to conform to the new KPI.

* Changes to MI Linux emulation code necessary to run 32-bit Linux binariestjr2004-08-161-0/+7
| | | | | | | | | | | | | | | 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.

* (This commit certainly increases the need for a wash&clean of vfs_cache.c,phk2003-03-171-409/+2
| | | | | | | | | | | | | | | | | but I decided that it was important for this patch to not bit-rot, and since it is mainly moving code around, the total amount of entropy is epsilon /phk) This is a patch to move the common parts of linux_getcwd() back into kern/vfs_cache.c so that the standard FreeBSD libc getcwd() can use it's extended functionality. The linux syscall linux_getcwd() in compat/linux/linux_getcwd.c has been rewritten to use it too. It should be possible to simplify libc's getcwd() after this. No doubt this code needs some cleaning up, since I've left in the sysctl variables I used for debugging. PR: 48169 Submitted by: James Whitwell <abacau@yahoo.com.au>

* - Replace v_flag with v_iflag and v_vflagjeff2002-08-041-1/+1
| | | | | | | | | | | | | | | - v_vflag is protected by the vnode lock and is used when synchronization with VOP calls is needed. - v_iflag is protected by interlock and is used for dealing with vnode management issues. These flags include X/O LOCK, FREE, DOOMED, etc. - All accesses to v_iflag and v_vflag have either been locked or marked with mp_fixme's. - Many ASSERT_VOP_LOCKED calls have been added where the locking was not clear. - Many functions in vfs_subr.c were restructured to provide for stronger locking.
