* Cleanup usage of free() in libkvm.zhuk2018-05-031-20/+11
| | | | okay deraadt@, otto@, tb@
* A few fixes for kvm_getargv(3)/kvm_getenv(3):zhuk2018-05-031-1/+10
| | | | | | | | | | | 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@

* fix a race when fetching files from the kernel. the number of filesdlg2015-09-041-4/+3
| | | | | | | | | | | | | | 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@

* Replace the old, broken KERN_PROC ABI and its matching functionsguenther2011-03-121-4/+1
| | | | | | | | | in libkvm with the stable-ABI versions that are currently named KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols will continue to be supported for a few releases. Committing now that they ports people have had a couple releases to update pkgs that usd the old functions
