| | | | | | | | | map the framebuffer as device memory in the kernel. Using mismatched memory attributes like this is discouraged (and we should probably fix this at some point) but this particular case is well-defined and the potential side-effects should not matter for thus use-case. ok patrick@
* Revert support for multiple threads to enter kqueue_scan() in parallel.mpi2017-12-182-64/+3
| | | | | | It is not clear if this change is responsible for the lockups experienced by dhill@ and jcs@ but since we're no longer grabbing the socket lock in kqueue(2) filters there's no need for this change.
* Revert grabbing the socket lock in kqueue(2) filters.mpi2017-12-183-28/+10
| | | | | | | | | | This change exposed or created a situation where a CPU started to be irresponsive while holding the KERNEL_LOCK(). These led to lockups and even with MP_LOCKDEBUG it was not clear what happened to this CPU. These situations have been experience by dhill@ with dcrwallet and jcs@ with syncthing. Both applications are written in Go and do kevent(2) & networking across multiple threads.
* Make rw_exit() always succeed after a panic.mpi2017-12-181-1/+5

* Add the CLOCK_BOOTTIME clockid for use with clock_gettime(2)cheloha2017-12-182-2/+5
| | | | | | | | | | | | | | | | | and put it to use in userspace in lieu of the kern.boottime sysctl. Its absolute value is the time that has elapsed since the system booted, i.e., the system uptime. Use in top(1), w(1), and snmpd(8) eliminates a race with settimeofday(2), adjtime(2), etc. inherent to deriving the system uptime via the kern.boottime sysctl. Product of a great deal of discussion/revision with jca@, tb@, and guenther@. ok tb@ jca@ guenther@ dlg@ mlarkin@ tom@

* ifq_barrier should be callable by any nic, not just MPSAFE ones.dlg2017-12-151-4/+1
| | | | | | | if (when) tx mitigation goes in again, all nics will have deferred work that will need a barrier to ensure isn't running anymore. found by bluhm@ when tx mit was in.
* add ifiqueues for mp safety and nics with multiple rx rings.dlg2017-12-155-78/+284
| | | | | | | | | | | | | | | | | | | | | | | | currently there is a single mbuf_queue per interface, which all rings on a nic shove packets onto. while the list inside this queue is protected by a mutex, the counters around it (ie, ipackets, ibytes, idrops) are not. this means updates can be lost, and reading the statistics is also inconsistent. having a single queue means that busy rx rings can dominate and then starve the others. ifiqueue structs are like ifqueue structs. they provide per ring queues, and independent counters for each ring. when ifdata is read for userland, these counters are aggregated. having a queue per ring now allows for per ring backpressure to be applied. MCLGETI will have it's day again. right now we assume every interface wants an input queue and unconditionally provide one. individual interfaces can opt into more. im not completely happy about the shape of this atm, but shuffling it around more makes the diff bigger. ok visa@
* make sched_barrier use cond_wait/cond_signal.dlg2017-12-142-23/+17
| | | | | | | | | | | previously the code was using a percpu flag to manage the sleeps/wakeups, which means multiple threads waiting for a barrier on a cpu could race. moving to a cond struct on the stack fixes this. while here, get rid of the sbar taskq and just use systqmp instead. the barrier tasks are short, so there's no real downside. ok mpi@

* If switching RW->RO, then stop deferring timestamp writes...and possiblyguenther2017-12-141-4/+16
| | | | | | | | | | other pending inode attribute changes. We appear to be missing UFS_UPDATE() calls in some paths with the result that bsd.rd remounting the newly created /mnt to RO would lose the GID changes on device inodes there. This only affected devices, as they're the only inodes where timestamp writes are delayed. ok deraadt@

* The pf code marks ICMP packets belonging to an TCP or UDP divertbluhm2017-12-142-19/+18
| | | | | | | | | | | | | | | | | state as diverted. This is necessary for IP input to accept the packet as ours. But it must not be used to match the ICMP packet to a raw socket. Clear the PF_TAG_DIVERTED mbuf pf flag for the special ICMP and ICMP6 packets in icmp_input_if() and icmp6_input(). The m_tag_delete_chain() caused an inconsistent PF_TAG_DIVERTED mbuf pf flag and PACKET_TAG_PF_DIVERT mbuf tag which triggered an assert in rip_input(). Deleting all mbuf tags can have undesired side effects and is not necessary anymore since icmp_reflect() calls m_resethdr(). Do not touch the mbuf tags and adjust the mbuf pf flags for the correct behavior of rip_input() and rip6_input(). reported by Chris Eidem, James Turner, vicviq, Scott Vanderbilt OK mpi@
