| | | | | | Apparently the boot rom on some cards leaves an interrupt vector set up, which will be run on completion of the first command after we set up the event queue, causing kernel crashes. chris@ reported this a while ago.

While here, only set up the available media types during attach, rather than on every mcx_media_status() call, as they don't reflect the type of module or cable present so they won't change over time. ok dlg@

* Prevent corruption of the pckbc command queue. If multiple synchronousanton2019-06-031-9/+27
| | | | | | | | | | | | | | commands are in flight and all corresponding threads are sleeping waiting for a response, the first command to timeout will clear the command queue. The remaining threads once awake will then try to remove a dequeued command from the queue, leading to corruption. Instead, remove commands from the queue before waking up the sleeping thread. A quirk is still needed to handle the case where tsleep() returns successfully during suspend. ok mpi@ visa@ Reported-by: syzbot+fe74fc50c630bfa26302@syzkaller.appspotmail.com

| | | | | | | | | | | one that will match any packet, used in promisc mode; one that matches on the low bit of the first byte of the destination mac address, used to receive all multicast packets; and one that matches on the whole destination mac address, used to receive unicast, broadcast and specific multicast addresses. As we add multicast addresses, we create flow entries to match them, but if we run out, we create an all-multicast flow entry. ok dlg@

* Switch from bintime_add() et al. to bintimeadd(9).cheloha2019-06-033-62/+55
| | | | | | | | | | | | | | | Basically just make all the bintime routines look and behave more like the timeradd(3) macros. Switch to three-argument forms for structure math, introduce and use bintimecmp(9), and rename the structure conversion routines to resemble e.g. TIMEVAL_TO_TIMESPEC(3). Document all of this in a new bintimeadd.9 page. Code input from mpi@, manpage input from schwarze@. code ok mpi@, docs ok schwarze@, docs probably still ok jmc@

* Refactor the MAP_STACK feature, and introduce another similar variation:deraadt2019-06-0113-225/+160
| | | | | | | | | Lookup the address that a syscall instruction is executed from, and kill the process if that page is writeable. This brings an aspect of W^X behaviour to W|X mappings (in JITs not yet adapted to W^X). The goal is to remove simple attack methods and force use of ret2libc or other more complicated means. ok kettenis stefan visa
* Bump VM_MAX_KERNEL_ADDRESS so that we have about 16G of KVA. Sincepatrick2019-06-011-2/+2
| | | | | | | | | we need KVA to keep track of all the RAM pages, machines with a lot of memory easily exhaust our KVA space. We need about 1G of KVA per 32G of memory, so with 16G of KVA we can maintain close to 512G of memory. ok kettenis@
* Revert to using the SCHED_LOCK() to protect time accounting.mpi2019-06-0114-101/+54
| | | | | | | | | It currently creates a lock ordering problem because SCHED_LOCK() is taken by hardclock(). That means the "priorities" of a thread should be moved out of the SCHED_LOCK() first in order to make progress.

* On machines with large amounts of physical memory we fail to initialize uvmkettenis2019-06-012-13/+66
| | | | | | | | | | because we don't have enough kernel memory available in the early bootstrap phase to allocate the vm_page structures. Fix this by making uvm_growkernel() work before uvm is initialized like we do on other architectures that don't use a direct map and explicitly call it after enumerating the available physical memory with an estimate of how much KVA we need to initialize uvm. ok patrick@
