2017-01-24In preparation of compiling our kernels with -ffreestanding, explicitly mapMark Kettenis
a few performance-critical functions to compiler builtins. Since the builtins supported by gcc3, gcc4 and clang are not the same, there are (unfortunately) some compiler checks to make sure we only do the mapping for builtins that are actually supported by the compiler. ok jca@, tom@, guenther@
2017-01-24In accept(2) and accept4(2) allocate a new file descriptor beforeMartin Pieuchot
checking if the socket head's queue is empty and possibly sleeping. This way we avoid lock ordering problems as the NET_LOCK() and fdplock() won't be held at the same time. Note that socketpair(2) and close(2) are the two remaining syscalls holding these locks at the same time. They both respect the same order: fdplock() then NET_LOCK(). Initial deadlock reported by kettenis@ and ajacoutot@. ok bluhm@, guenther@, deraadt@

2017-01-24Track a per-fd flag UF_PLEDGED. This indicates the initial open was done by aTheo de Raadt
pledged process. dup(2) and recvmsg(2) retain UF_PLEDGED from the original fd. In pledge "exec" circumstances, exceve clears UF_PLEDGED on all the process's fds. In a pledge'd process, ioctl(2) can use this additional information to grant access to ioctl's which are more sensitive or dive deeply into the kernel. Developers will be encouraged to open such sensitive resources before calling pledge(2), rather than afterwards. That matches the heading of privsep development practices. Future changes will introduce those ioctl(2) changes. Lots of discussions with semarie guenther and benno.
2017-01-24add support for multiple transmit ifqueues per network interface.David Gwynne
an ifq to transmit a packet is picked by the current traffic conditioner (ie, priq or hfsc) by providing an index into an array of ifqs. by default interfaces get a single ifq but can ask for more using if_attach_queues(). the vast majority of our drivers still think there's a 1:1 mapping between interfaces and transmit queues, so their if_start routines take an ifnet pointer instead of a pointer to the ifqueue struct. instead of changing all the drivers in the tree, drivers can opt into using an if_qstart routine and setting the IFXF_MPSAFE flag. the stack provides a compatability wrapper from the new if_qstart handler to the previous if_start handlers if IFXF_MPSAFE isnt set. enabling hfsc on an interface configures it to transmit everything through the first ifq. any other ifqs are left configured as priq, but unused, when hfsc is enabled. getting this in now so everyone can kick the tyres. ok mpi@ visa@ (who provided some tweaks for cnmac).

2017-01-24Introduce rt_report() a function that generates a route message from anClaudio Jeker
rt_entry. Use this function in the success case of all route commands. Reduce the goto madness in route_output and make the code hopefully a bit easier to read and work with. OK mpi@ bluhm@
2017-01-23File descriptor passing internalizes fd's into an mbuf-stored array ofTheo de Raadt
struct file *, and then externalizes back to fd upon delivery. Convert storage to array of struct fdpass, containing struct file * (and soon something else). memcpy originally intended for alignment purposes can be removed because CMSG_ALIGN is _ALIGN. There is some anxiety over changing this code, but it reads easier. ok mpi guenther kettenis

2017-01-23The function raw_input() has not been called since netiso has beenAlexander Bluhm
removed in 2004. The comment about raw_input() above rip_input() was added in 1981, but it is wrong since 1992. After that it has been copied to rip6_input(). (*pr_input)() is never called with the parameters (mbuf, sockproto, sockaddr, sockaddr). So retire raw_input(). OK guenther@ deraadt@
