| | | | | | | | | | | | | | vop_stdallocate() is filesystem agnostic and will run as slow as a read/write loop in userspace; however, it serves to correctly implement the functionality for filesystems that do not implement a VOP_ALLOCATE. Note that __FreeBSD_version was already bumped today to 900036 for any ports which would like to use this function. Also reserve space in the syscall table for posix_fadvise(2).

* Use atomic load & store for TSC frequency. It may be overkill for amd64 butjkim2011-04-071-3/+5
| | | | | | | | | safer for i386 because it can be easily over 4 GHz now. More worse, it can be easily changed by user with 'machdep.tsc_freq' tunable (directly) or cpufreq(4) (indirectly). Note it is intentionally not used in performance critical paths to avoid performance regression (but we should, in theory). Alternatively, we may add "virtual TSC" with lower frequency if maximum frequency overflows 32 bits (and ignore possible incoherency as we do now).

* Implement compat32 shims for PCIOCGETCONF.kib2011-04-021-0/+106
| | | | | | | | | | | | There is a generic problem with the shims for ioctls that receive pointers to the usermode data areas in the data argument. We either have to modify the handler to accept UIO_USERSPACE/UIO_SYSSPACE indicator, or allocate and fill a usermode memory for data buffer in the host format. The change goes the second route, in particular because we do not need to modify the handler. Submitted by: John Wehle <john feith com> MFC after: 2 weeks

* Revert r220032:linux compat: add SO_PASSCRED option with basic handlingavg2011-03-311-14/+0
| | | | | | | | | | I have not properly thought through the commit. After r220031 (linux compat: improve and fix sendmsg/recvmsg compatibility) the basic handling for SO_PASSCRED is not sufficient as it breaks recvmsg functionality for SCM_CREDS messages because now we would need to handle sockcred data in addition to cmsgcred.

* Fix some locking nits with the p_state field of struct proc:jhb2011-03-241-2/+0
| | | | | | | | | | | | | | | | | | - Hold the proc lock while changing the state from PRS_NEW to PRS_NORMAL in fork to honor the locking requirements. While here, expand the scope of the PROC_LOCK() on the new process (p2) to avoid some LORs. Previously the code was locking the new child process (p2) after it had locked the parent process (p1). However, when locking two processes, the safe order is to lock the child first, then the parent. - Fix various places that were checking p_state against PRS_NEW without having the process locked to use PROC_LOCK(). Every place was already locking the process, just after the PRS_NEW check. - Remove or reduce the use of PROC_SLOCK() for places that were checking p_state against PRS_NEW. The PROC_LOCK() alone is sufficient for reading the current state. - Reorder fill_kinfo_proc() slightly so it only acquires PROC_SLOCK() once. MFC after: 1 week
