* These NDINIT run out of the context of the process doing execve,deraadt2015-11-051-1/+5
| | | | | so PS_PLEDGE is active. PLEDGE_EXEC must be noted for the namei operations, so that the action is understood by the namei check code.

* emul_native is only used for kernel threads which can't dump core, soguenther2015-05-051-3/+2
| | | | | | | | | | | delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump, and various #includes that are superfluous. This leaves compat_linux processes without a coredump callback. If that ability is desired, someone should update it to use coredump_elf32() and verify the results... ok kettenis@

* Indroduce fd_getfile_mode() and use it were fd_getfile() is directlympi2015-04-302-14/+4
| | | | | | | followed by a mode check. This will simplify the ref/unref dance as soon as fd_getfile() will increment fp's reference counter. Idea from and ok guenther@, ok millert@

| | | | optval is not valid. Found by Maxime Villard. OK bluhm@
* Move the "stackgap" from the stack into its own page at a random address.kettenis2015-01-261-10/+16
| | | | | | | This allows us the unmap the initial part of the stack, such that it can't be used as a staging area for ROP (or other) attacks. ok guenther@, tedu@

* Delete option COMPAT_43: support for pre-sa_len binaries has been obsoleteguenther2015-01-211-8/+22
| | | | | | | | for a couple decades. Keep the OSIOCGIFCONF ioctl to support COMPAT_LINUX but move the rest of the Linux-specific ioctl() handling into linux_socket.c This lets struct osockaddr finally move from sys/socket.h to protocols/talkd.h ok krw@ deraadt@ mpi@
* Prefer linux_sockaddr over osockaddr, so the latter can go away.guenther2015-01-193-193/+68
| | | | | | | | | | | sys_socket() supports SOCK_{CLOEXEC,NONBLOCK} now, so build on that. doaccept() supports the non-inheriting-of-O_NONBLOCK, so build on that. Merge compat_sys_{accept,send,recv}() into their only callers. Lie a little and use struct sockaddr in the linux socket syscall args when it's a return argument to avoid a bunch a casts. Delete many other unnecessary sockaddr casts verified with a curl Linux binary

* primary change: move uvm_vnode out of vnode, keeping only a pointer.tedu2014-12-161-1/+3
| | | | | | objective: vnode.h doesn't include uvm_extern.h anymore. followup changes: include uvm_extern.h or lock.h where necessary. ok and help from deraadt

* Replace a plethora of historical protection options with justderaadt2014-11-161-3/+3
| | | | | | | PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h. PROT_MASK is introduced as the one true way of extracting those bits. Remove UVM_ADV_* wrapper, using the standard names. ok doug guenther kettenis

* Retire kernel support for SO_DONTROUTE, this time without breakingmpi2014-04-071-3/+1
| | | | | | | | | | | localhost connections. The plan is to always use the routing table for addresses and routes resolutions, so there is no future for an option that wants to bypass it. This option has never been implemented for IPv6 anyway, so let's just remove the IPv4 bits that you weren't aware of. Tested a least by lteo@, guenther@ and chrisz@, ok mikeb@, benno@

* Move p_emul and p_sigcode from proc to process.guenther2014-03-2612-70/+70
| | | | | | | | | Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

| | | | | | | | Linux-compat clone() syscall when *not* using CLONE_THREAD. pirofti@ confirms Opera runs in compat without this, so out it goes; one less hair to choke on in kern_exit.c ok tedu@ pirofti@
* Try to cope better with void pointer to int usage cases.pirofti2014-01-231-3/+5
| | | | | | | Use intptr_t for such cases. More casts/types should be improved in this file. Tested with syscall regression tests from IBM.
