file always after creation to cache the inode number given by the
backend file system. Otherwise we would not find a newly created
node from incore and create another one. In practise this was
pretty well hidden by the kernel name cache.
avoid wasting OS flag bits. In the future we'll probably use fileassoc to
achieve this (once there is a way to make fileassoc persistent) or in the
shorter term libelf, so that we can add and remove the note on demand instead
of burning bits on each binary. Of course since this is a tool, this means
that we'll need to think about how to handle libelf...
this one, since it's a good exercise ..
Add icfs, which does the same thing as the refuse-based icfs agc
added earlier this week, i.e. null-mounts & converts the entire
namespace to lowercase. However, it's a fun comparison, since this
is implemented in a completely different fashion from the refuse
version.
so that it isn't necessary to copy data to/from the stackgap.
Given the nature of the code in this file, it is now probably slightly
more broken than previously. but nothing serious should be worse!
in order to avoid the stackgap (etc).
Note that since changing the darwin socket address is simply a matter of
translating the address family and adding sa_len, it can easily be done
on the mbuf resident address before/after copying to/from userspace.
Simplify the convertion of AF_LOCAL addresses by usingthe user-supplied
buffer length instead of dowing an unbounded strlen().
Untested - did this work before?
'name' is wanted in kernel code.
Similarly split sys_accept() and change the split in recvmsg() so that it
is useful to the compat functions, recvit() is removed and replaced by
do_sys_recvmsg().
Factor out the code that writes socked names to userspace (from mbuf) to
avoid replicated code.
Extract the code that writes socket 'control' (CMSG) data out to userspace,
being more careful about the 'fd' that may exist inside SCM_RIGHTS msgs.
(they still get lost if some of the latter copyout calls fail).
Since these are new functions, and old LKMs will fail to load.
and destroyed, but not yet reclaimed. This prevents puffs_pn_nodewalk()
from returning stale entries. Make nullfs use this (some file
systems are a bit too happy with recycling inode numbers).
