2015-01-05splassert on some archs (or just sparc64) check that you're not inDavid Gwynne
an interrupt handler at an ipl level higher than what you're splasserting you should be at. if you think code should be protected by IPL_BIO and its entered from an interrupt handler established at IPL_NET, you have a bug. add some asserts to gets and puts so we can pick those cases up.
2015-01-04back out r1.173, aka the "* 8" diff. it tickles a problem on someDavid Gwynne

2014-12-28The greatest happiness is to scatter inferiour APIs, to drive themKenneth R Westerback
before you, to see their files reduced to ashes, to see those who love them shrouded in tears, and to gather into your API all their invocations. In other words, workq is no more. There is only taskq. ok kettenis@ dlg@ (creator of taskq) jmc@

(which we never did, but it was a bug nonetheless). ok kettenis, deraadt
2014-12-22Make it possible to execute PIE binaries that don't have an PT_INTERP segmentMark Kettenis
(and therefore no interpreter). Necessary to make self-relocating "static" PIE working. This will also allow execution of shared libraries that have the 'x' bit set. Those shouldn't exist, but unfortunately people outside OpenBSD think differently which means third-party software sometimes installs shared libraries with the 'x' bit set. ok kurt@, deraadt@

2014-12-19timestamp empty pages, and only free them if theyve been idle for at leastDavid Gwynne
a second. this basically brings back the functionality that was trimmed in r1.53, except this version uses ticks instead of very slow hardware clock reads. ok tedu@
2014-12-19the last commit changed LIST_INSERT_HEAD to TAILQ_INSERT_TAIL cos theDavid Gwynne
latter is cheaper, but i forgot to change the thing that pulls pages off those lists to match the change in direction. the page lists went from LIFO to FIFO. this changes pool_update_curpage to use TAILQ_LAST so we go back to LIFO. pointed out by and ok tedu@
2014-12-19replace the page LISTS with page TAILQs. this will let me pull pages fromDavid Gwynne
either end of the lists cheaply. ok kettenis@ tedu@

2014-12-05Introduce a new sysctl to retrieve VM map entriesMasao Uebayashi
This adds a new sysctl KERN_PROC_VMMAP, which returns an array of VM map entries of a specified process. This prevents debuggers from iterating vm_map_entry RB tree via kvm(3). The name KERN_PROC_VMMAP and struct kinfo_vmentry are chosen from the same function in FreeBSD. struct kinfo_vmentry is revised to reduce size, because OpenBSD does not keep track of filepaths. The semantic is also changed to return max buffer size as a hint, and start iteration at the specified base address. Much valuable input from deraadt@, guenther@, tedu@ OK tedu@ deraadt@

2014-12-01clist's chained, and could get fairly long which is why there was aTheo de Raadt
dynamic clamping mechanism. In the (new? has it already been 20 years?) world of tty ring buffers, c_cn is the maximum... There could be some ugly limit elsewhere, which may cause a deadlock (dug as deep as my patience allows), so please report any sort of new console or xterm issues that show up, such as tty lockups or high cpu utilization..

2014-11-19missed a file when removing KERN_VNODE.Ted Unangst
2014-11-19delete the KERN_VNODE sysctl. it fails to provide any isolation from theTed Unangst
kernel struct vnode defintion, and the only consumer (pstat) still needs kvm to read much of the required information. no great loss to always use kvm until there's a better replacement interface. ok deraadt millert uebayasi

Regression spotted by tobiasu@. XXX I wonder if the page zeroing thread shouldn't perform explicit XXX pmap_update(pmap_kernel()) calls after each page zeroing... but that XXX might not be enough.
