* fix a race when fetching files from the kernel. the number of filesdlg2015-09-041-36/+41
| | | | | | | | | | | | | | 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@
* Rework the UNIX domain socket garbage collector, including ideas fromguenther2015-08-281-2/+2
| | | | | | | | | | | | | {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@

* Put the socket splicing fields into a seperate struct sosplice thatbluhm2014-11-031-6/+14
| | | | | | | 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@

* Track whether a process is a zombie or not yet fully built via flagsguenther2014-07-041-29/+29
| | | | | | | | | | | 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@
* Eliminates struct pcred by moving the real and saved ugids intoguenther2014-03-301-11/+4
| | | | | | | | | struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

| | | | | | | | | | - convert netstat from kvm_getfiles() to kvm_getfile2() using that - delete kvm_getfiles() and KERN_FILE as no longer used (bump libkvm's major) - rename kvm_getfile2() to kvm_getfiles(), kinfo_file2 to kinfo_file and KERN_FILE2 to KERN_FILE. ok deraadt@, millert@ ports scan sthen@

* Reimplement kvm_getproc2()'s support for reading crash dumps andguenther2010-01-101-3/+1
| | | | | | | | | | | | | | /dev/mem to be direct instead of going through kvm_getprocs(), as that function is going to get more an more broken as we move stuff from struct proc to struct process for rthreads. To minimize the code copying, put the common logic of filling in a kinfo_proc2 structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from both the kernel and user-space. This also hides the KERN_PROC #define behind "#if defined(_KERNEL)||defined(_LIBKVM)", as it's deprecated. Positive feedback from millert and blambert; so committing to unblock further rthreads work.
