happen in the TCP stack, this interface calls the specified callback to
handle the situation according to the currently selected congestion
control algorithm.
A new sysctl node was created: net.inet.tcp.congctl.{available,selected}
with obvious meanings.
The old net.inet.tcp.newreno MIB was removed.
The API is discussed in tcp_congctl(9).
In the near future, it will be possible to selected a congestion control
algorithm on a per-socket basis.
Discussed on tech-net and reviewed by <yamt>.
- remove any 'permission checks' via geteuid() - with upcoming
security models these might not match the model any more
- this also fixes a bug where ntp_adjtime() was denied (EPERM)
even though only a legit read status was performed
always using "function" instead of "macro".
Changed "undefined result" into "undefined behavior" for argument values
outside the valid range. Since the character table is allocated via
malloc(), it _may_ happen that it starts at a page boundary, so that
negative values for the argument result in a segmentation fault. In that
case, there is no result at all.
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:
- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
now take the cmd argument rather than the file open flag. The
read-ness or write-ness of an ioctl command is checked by these
routines to ensure that information is being passed to/from the
userland component properly.
- prop_dictionary_copyout_ioctl() now allocates the memory for the
XML plist on behalf of the userland component by way of uvm_mmap().
The XML plist is copied out to the newly-mapped anonymous region,
and the pointer returned via the plistref.
- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
region after parsing the XML plist into internal represenatation.
- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
code to send a dictionary to the kernel and receive one back as a
reply.
Update users of prop_kern for the API changes (Bluetooth).
This constitutes an ABI / protocol change -- but this will also be put
into NetBSD 4.0 so that the first proplib release will implement the new
scheme.
_{files,dns,yp}_getenetbyaddr() functions from unsigned long to uint32_t.
In rev 1.29, getnetbyaddr(3) was changed to take uint32_t `net' argument
and also passisng uint32_t `net' to nsdispatch(3) varargs, but
these callback functions were not changed accordingly.
Patch was provided by christos, and this fixes amd(8) coredumps on alpha
when /etc/nsswitch.conf has more than one sources for netgroups.
