2016-05-26Make amaps use less kernel memory (2nd try)Stefan Kempf
The original diff would crash at least i386 and powerpc, as spotted by guenther@ The reason was an incorrect use of sizeof in amap_lookups(). Confirmation that powerpc works by mpi@ and mglocker@ "throw it in" deraadt@ Original commit message: This is achieved by grouping amap slots into chunks that are allocated on-demand by pool(9). Endless "fltamapcopy" loops because of kmem shortage should be solved now. The kmem savings are also important to later enable vmm(4) to use larged shared memory mappings for guest VM RAM. This adapts libkvm also because the amap structure layout has changed. Testing and fix of libkvm glitch in initial diff by tb@ Feedback and "time to get this in" kettenis@
2016-05-22Revert previous: breaks i386 and powerpc, probably all non-PMAP_DIRECT archsPhilip Guenther

there is a big fat comment saying "Avoid alignment issues" immediately above them.
2016-05-11remove hppa64 port, which we never got going beyond broken single users.Theo de Raadt
hppa reverse-stack gives us a valuable test case, but most developers don't have a 2nd one to proceed further with this. ok kettenis

2016-05-04Add ERRORS section (requested by bluhm@). While there, move start ofVadim Zhukov
RETURN VALUES section upper, where it belongs more.

2016-03-30for some time now mandoc has not required MLINKS to functionJason McIntyre
correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

2015-09-08port the changes just made to kvm_getfiles in kvm_file2.c r1.47 toDavid Gwynne
kvm_getprocs. basically cope with the number of procs growing between when we get the size and when we get the list. ok guenther@
2015-09-04fix a race when fetching files from the kernel. the number of filesDavid Gwynne
might have increased between when we got the number of files and when we requested that number of files. now we allocate another 10ish percent on top of what the kernel says we need, and retry if that still isnt enough. while here use realloc instead of constantly going through free/malloc sequences. with input from claudio@ deraadt@ ok millert@ guenther@

part of a larger diff ok millert@ guenther@
2015-08-28Rework the UNIX domain socket garbage collector, including ideas fromPhilip Guenther
{Free,Net}BSD - when a socket is closed with fds in its input, defer closing them to a task to avoid recursing. This eliminates the complicated extra reference taking which had a 37 line(!) comment explanation - move flags, counts, and links only needed for this from struct file to struct unpcb - document the flow of the mark/sweep collector much help from claudio@ who made me explain the GC to him until we trusted it ok claudio@ mpi@ deraadt@
2015-05-11When checking flags that will be passed to open(), test the O_ACCMODE portionPhilip Guenther
separately to avoid false negatives. ok miod@ millert@
2015-04-07Teach libkvm a bit about PAE, making it independent of the kernel definesPhilip Guenther
and doing runtime detection of what the target kernel is using. Getting this is now to avoid breakage when kernel bits come. ok deraadt@

Found a while ago when porting cpulimit. ok deraadt@
2015-03-30Do not include <machine/autoconf.h>, for it is a kernel-only header and libkvmMiod Vallat
doesn't need anything from it. While there, fix format strings and remove unused local variable declarations.
2015-03-28Replace the hand-crafted list of datagram unix domain sockets withAlexander Bluhm
a SLIST. OK mpi@ benno@
2015-03-18Rework the virtual memory layout on SRMMU systems (sun4d/sun4m) to use a muchMiod Vallat
lower VM_MIN_KERNEL_ADDRESS, since these systems are not crippled by the Sun-4 MMU hole and have the real 4GB of address space. Kernels running on Sun-4 MMU are not affected and will still be restricted to the existing 128MB of kernel space, with 1GB - 128MB of user space. Kernels running on SRMMU will now provide the low 3GB of address space to userland, and use the top 1GB for the kernel, except when compiled with option SMALL_KERNEL, in which case they will keep Sun-4 style the layout (this is temporary to allow for people to boot bsd.rd to upgrade even when not running 2.10 boot blocks, and will be removed eventually) A consequence of this is that the top of the userland stack is no longer at 0xf0000000. But since nothing in userland uses USRSTACK anymore, this should not be an issue. Tested on sun4c and various sun4m, with physical memory sizes ranging from 32 to 448MB.
2015-02-11Extend struct kinfo_file a bit for netstat (sync with the kernel).Claudio Jeker
Bump minor number because of this. OK guenther@

2015-02-11sysctl({CTL_KERN, KERN_FILE, KERN_FILE_BYFILE}) previously requiredPhilip Guenther
the extra argument to be zero; instead, make it filter on the file type (DTYPE_*) when non-zero to make claudio's netstat work easier. ok claudio@

2014-11-03Put the socket splicing fields into a seperate struct sosplice thatAlexander Bluhm
gets only allocated when needed. This way struct socket shrinks from 472 to 392 bytes on amd64. When splicing gets active, another 88 bytes are allocated for struct sosplice. OK dlg@

PS_{ZOMBIE,EMBRYO} on the process instead of peeking into the process's thread data. This eliminates the need for the thread-level SDEAD state. Change kvm_getprocs() (both the sysctl() and kvm backends) to report the "most active" scheduler state for the process's threads. tweaks kettenis@ feedback and ok matthew@

this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
