2021-07-12Change the error reporting pattern throughout the tree when unveilBob Beck
fails to report the path that the failure occured on. Suggested by deraadt@ after some tech discussion. Work done and verified by Ashton Fagg <ashton@fagg.id.au> ok deraadt@ semarie@ claudio@

2019-10-14pledge() won't work but we can use unveil() to reduce filesystem accessTheo de Raadt
in these 3 related programs (they borrow parts of each other using .PATH) Hopefully no regressions, ktrace checks by myself and mestre

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.

2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2014-07-02populate pool npages, as per src/sys/kern/subr_pool.c r1.135David Gwynne
2014-07-02info about pools is currently given to userland by copying eachDavid Gwynne
pools struct out. however, struct pool in the kernel contains lots of things that userland probably isnt interested in, like actual mutexes, and probably shouldnt get easy access to, like pointers to kernel memory via all the lists/trees. this implements a kinfo_pool structure that has only the data that userland needs to know about. it cuts the sysctl code over to building it from struct pool as required and copying that out instead, and cuts userland over to only handling kinfo_pool. the only problem with this is vmstat, which can read kernel images via kvm, which needs some understanding of struct pool. to cope, the struct pool definition is guarded by if defined(_KERNEL) || defined(_LIBKVM) as inspired by sysctl which needs to do the same thing sometimes. struct pool itself is generally not visible to userland though, which is good. matthew@ suggested struct kinfo_pool instead of struct pool_info. the kinfo prefix has precedent. lots of people liked this.
2014-04-08Use VM_UVMEXP instead of VM_METER for memory usages and directlyMartin Pieuchot
include <sys/vmmeter.h> where it is needed instead of relying on it being included by <uvm/uvm_extern.h>. miod@ likes it, ok guenther@

2013-07-18There is no uvm_km_pages_free in our kernel anymore. The correspondingAlexander Bluhm
lines in dopool_sysctl() have been removed from vmstat.c revision 1.116. Remove uvm_km_pages_free from dopool_kvm() to allow analysing a core dump. OK guenther@ miod@

2009-10-28rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andTheo de Raadt
unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
