2021-12-01sys/core.h is not needed by these files, therefore sys/param.h isn'tTheo de Raadt
needed for MAXCOMLEN either
2021-12-01Reduce use of sys/param.h, or annotate the reason why it is neededTheo de Raadt
(pretty much MAXCOMLEN for struct process or struct core), and remove sys/vnode.h where not needed
2021-12-01Use system _ALIGN to reduce the reasons why this uses sys/param.hTheo de Raadt
2021-10-06annotate sys/param.h uses as required, and pull in standard userlandTheo de Raadt
.h files as required.... preparing for a potential future when sys/proc.h might be more clean... do not touch the MD .c files yet, the dragons remain full of fire
2021-09-10annotate what symbols are used from sys/param.h lines, or delete themTheo de Raadt
if not required. when deleting, add sys/signal.h or other lines which were not being pulled in

2021-02-08Revert the convertion of per-process thread into a SMR_TAILQ.Martin Pieuchot
We did not reach a consensus about using SMR to unlock single_thread_set() so there's no point in keeping this change.

Currently all iterations are done under KERNEL_LOCK() and therefor use the *_LOCKED() variant. From and ok claudio@

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

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@

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@

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

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.

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@
