2020-06-28Fix grammar in comment.Mark Kettenis
2020-06-25Add missing kvm_dump(3) and kvm_getfiles(3) under SEE ALSO for completenesskn
2019-12-11add sys/wait.h to unbreak builds; following "Replace p_xstat with ps_xexit andStuart Henderson

2019-10-22struct proc: change ps_start from utc time to uptimecheloha
Allows us to determine how long a process has been running, even if the UTC clock jumps. With help from bluhm@ and millert@, who squashed several bugs. ok bluhm@ millert@
2019-08-11No specific called "exec(3)", so move primary manpage to a name whichTheo de Raadt
does exist -- execv(3). Still call this a family but without "Nm". Adjust Xr in various pages to refer to the precise function used rather than the family, in most cases the semantics of execve(2) are being referenced, so change the Xr. ok jmc
2019-06-28When system calls indicate an error they return -1, not some arbitraryTheo de Raadt
value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.
2019-06-23Export unveil state so that ps(8) can show it. Two new status flags,Theo de Raadt
you'll see one, or neither. 'u' - process installed unveils, but not yet locked with unveil(0,0) or pledge w/o "unveil" 'U' - process has installed unveils, and locked. ok rob

okay deraadt@, otto@, tb@
2018-05-03A few fixes for kvm_getargv(3)/kvm_getenv(3):Vadim Zhukov
1. Most notable: this splits argv buffer into argv-specific one and environ-specific one. This makes ps -eww totally happy. 2. realloc() usage in kvm_argv() is now ENOMEM-prone. 3. The "int off" changed to "ptrdiff_t off", as it should be. input & okay deraadt@, millert@

2017-12-14Add Symbols.map to explicitly define the ABIs, hiding linker defined symbols.Philip Guenther
Use hidden aliases for internal invocations of exported symbols to avoid PLT. ok deraadt@ kettenis@ jca@

struct proc to struct process. ok deraadt@ kettenis@
2017-01-11Add "support" for OpenBSD/arm64 so that it compiles. It's a copy ofPatrick Wildt
the 32-bit ARM version and might need updates.

from Sebastien Marie
2016-09-16handle fallout of moving the address maps to RBT code.David Gwynne
because userland doesnt have subr_tree, and the tree traversal in this file is simple, this inlines the logic that the functions in the kernel do.

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

2016-05-14Revert previous commit. Converting bcopy into memcpy is never safe whenMark Kettenis
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

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@
2015-04-04The swapfile argument is also const char *.Jeremie Courreges-Anglas
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@
2015-02-11Prefer arg != 0 over arg for non-boolean. nitted kettenis@Philip 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@
