2012-01-11If the DUID of the boot disk has not been provided, attempt to locate itJoel Sing
via the boot device. This allows root on softraid to work on most architectures. For architectures that cannot clearly identify their boot device, the DUID of the boot disk can still be passed from the boot loader, as is already done for amd64 and i386. Based on a suggestion from kettenis@ ok krw@
2012-01-11Move softraid root mapping to later in the boot process - this will allowJoel Sing
us to play some tricks in setroot().

No binary change. ok mikeb@ deraadt@ guenther@
2012-01-07Add rtable id and thread id to struct kinfo_proc (and fix process id)Philip Guenthe
and add an 'rtableid' keyword to ps. Add rtable id, thread id, and socket splice info to struct kinfo_file2 and make fstat display socket splice information. Remove old KVM_PROC2 and kinfo_proc2 interfaces; bump libkvm major Socket splice info and corrections from bluhm@ "Lovely" deraadt@
2012-01-04Fix use after free in cache_lookup() - found by PedroBob Beck
fix is to manipulate the name cache structures before potentially sleeping on a vn_lock(). This avoids the race of the ncp entry being recycled while we are asleep. run in snaps and on ftp.openbsd.org for months ok thib@

2011-12-28Avoid the use of an invalid disklabel by setting a DK_LABELVALID flagJoel Sing
if we correctly read and validated the disklabel. Always check that this flag is set before using the DUID from the disklabel. Discussed with deraadt@ ok krw@
2011-12-28An all-zero DUID is considered to be a blank DUID - ensure that we do notJoel Sing
generate one. ok krw@
2011-12-14Handle rthreads consistently in ktrace by moving the flags and vnode intoPhilip Guenthe
struct process; KTRFAC_ACTIVE becomes P_INKTR. Also, save the credentials used to open the file in sys_ktrace() and use them for all writes to the vnode. much feedback and ok jsing@

2011-12-02dont put MAXMCLBYTES in the mclsizes array with a comment saying its 64kDavid Gwynne
when the macro can change without automatically fixing the comment. instead add a diagnostic that checks that the biggest cluster size is always MAXMCLBYTES. requested by and ok kettenis@
2011-11-30this diff introduces the MAXMCLBYTES macro to describe the largestDavid Gwynne
cluster the generic network stack will be able to give you. it also recognises that external storage on an mbuf may be bigger than MCLBYTES. its only when m_pullup or m_pulldown need to allocate another cluster that they now check the len argument, and now they do it against MAXMCLBYTES. this is required for me to do pfsync on jumbo frames as the m_pulldown for the subregions fail beyond MCLBYTES into the packet. ok deraadt@ mikeb@ henning@ blambert@ manpage changes ok jmc@

2011-11-23block interrupts while pool_reclaim_all is grubbing around in every poolsDavid Gwynne
internals. this fixes a panic i got where a network interrupt tried to use the mbuf pools mutex while pool_reclaim_all already held it which lead to the same cpu trying to lock that mutex twice. ok deraadt@
2011-11-22Move struct proc's sigaltstack struct from the zeroed area into theJoshua Elsasser
copied area, and initialize it properly in the FORK_THREAD case. This restores the behavior of a forked process inheriting its parent's signal stack. ok guenther@

ahci_hibernate_io, a skeleton of which is also provided in this diff. This code is from deraadt@. Tested on a few wd machines to ensure it works there as well.

2011-11-05I had moved earlier the adding of processes to the pgrp and children listsPhilip Guenthe
during the big rework at c2k10, but it's too early as signals can be posted before the process is fully built. Move those list adds back down to the late stage they were before. Problem seen on sebastia@'s sparc. ok deraadt@ miod@

2011-10-27Allow segments to be used even after they were marked for deletion withRobert Nagy
the IPC_RMID flag. This is permitted as an extension beyond the standards and this is similar to what other operating systems like linux do. Because compat_linux(8) was emulating this already, remove that code since now this is the default. input from oga@, guenther@, jmc@, deraadt@ ok deraadt@

2011-10-15"TLS-lite": add kernel support for a per-thread userspace pointer,Philip Guenthe
for pointing to the thread-control-block. Support for mapping this to the correct hardware register can be added as it's finished; start with support for amd64, sparc, and sparc64. Includes syscalls for getting and setting it (for a portable __errno implementation) as well as creating a new thread with an initial value for it. discussed with miod@, kettenis@, deraadt@; committing to get the syscalls in with the impending libc bump and do further refinements in tree

they apply. ok oga@ deraadt@
2011-10-06Introduce a kqfilter wrapper for the controlling tty device entryMike Belopuhov
which allows a correct registration of kqueue(2) notifications on the /dev/tty instead of calling a function via a null pointer in the ttkqfilter leading to a local DoS. Surprisingly the same code is present in NetBSD since the kqueue merge, but didn't make it to the OpenBSD for 10 years. Thanks to Anton Yabchinskiy <arn-at-bestmx-dot-ru> for a GHCi crash report and his willingness to test multiple diffs for over a week. With input from nicm, ok miod, derraadt.
