Fewer pool_get() in kqueue_register()

Diff below changes the order of operations in kqueue_register() to get rid of an unnecessary pool_get(). When an event is already present on the list try to acquire it first. Note that knote_acquire() may sleep in which case the list might have changed so the lookup has to always begin from the

openrsync(1): add support for IPv6-only hosts

Hello, The current openrsync client is not able to connect to dual-stack remote hosts, when the local host does not have any IPv4 connectivity. This is because connect() fails with EADDRNOTAVAIL when trying to connect to the remote IPv4 address on an IPv6-only local host - and IPv4 seems to be

Push KERNEL_LOCK/UNLOCK in trapsignal()

Taken from a larger diff from claudio@, this reduces the lock dances in MD code and put it where we should focus our effort in kern/kern_sig.c. ok? Index: kern/kern_sig.c === RCS file: /cvs/src/sys/kern/kern_sig.c,v retrieving

slaacd(8): use correct source link-layer address

When sending a router solicitation use the link-layer (mac) address of the outgoing interface in the source link-layer address ICMPv6 option instead of the address of the last configured autoconf interface. It is not the most efficient way to first transform an if_index into and interface name

Log mutex for msgbuf concurrency control

This diff introduces a mutex that serializes access to the kernel message buffers. At the moment, the buffers do not have clear concurrency control. The mutex controls access to all the modifiable fields of struct msgbuf. It also protects logsoftc.sc_state for managing thread wakeups. A tricky

PATCH: VMD fixes for PCI Config Space and BAR Allocation [passthrough PCI support]

This is the first patch for adding PCI passthrough support to VMD. I am splitting up the necessary changes into smaller patches. This code fixes the pci device union for accessing PCI config space >= 0x40 pcidump -xxx would return garbage data due to union overlap pci_add_bar now requires
