d57486e21c Updates to libprocstat(3) and procstat(1) to allow monitoring Capsicum
capability mode and capabilities.

Right now no attempt is made to unwrap capabilities when operating on
a crashdump, so further refinement is required.

e95725cb76 Most of these changes to isp are to allow for isp.ko unloading.
We also revive loop down freezes. We also externaliz within isp
isp_prt_endcmd so something outside the core module can print
something about a command completing. Also some work in progress to
assist in handling timed out commands better.

fd9a5f73f6 When falloc() was broken into separate falloc_noinstall() and finstall(),
a bug was introduced in kern_openat() such that the error from the vnode
open operation was overwritten before it was passed as an argument to
dupfdopen().  This broke operations on /dev/{stdin,stdout,stderr}.  Fix
by preserving the original error number across finstall() so that it is
still available.

bc69c09054 Allow openat(2), fstatat(2), etc. in capability mode.
namei() and lookup() can now perform "strictly relative" lookups.
Such lookups, performed when in capability mode or when looking up
relative to a directory capability, enforce two policies:
 - absolute paths are disallowed (including symlinks to absolute paths)
 - paths containing '..' components are disallowed

These constraints make it safe to enable openat() and friends.
These system calls are instrumental in supporting Capsicum
components such as the capability-mode-aware runtime linker.

Finally, adjust comments in capabilities.conf to reflect the actual state
of the world (e.g. shm_open(2) already has the appropriate constraints,
getdents(2) already requires CAP_SEEK).

69d377fe1b Allow Capsicum capabilities to delegate constrained
access to file system subtrees to sandboxed processes.

- Use of absolute paths and '..' are limited in capability mode.
- Use of absolute paths and '..' are limited when looking up relative
  to a capability.
- When a name lookup is performed, identify what operation is to be
  performed (such as CAP_MKDIR) as well as check for CAP_LOOKUP.

With these constraints, openat() and friends are now safe in capability
mode, and can then be used by code such as the capability-mode runtime
linker.

a0108be612 Test *at(2) calls with capability-mode lookup.
This commit adds regression testing for openat(), fstatat(), etc. with
capability scoping ("strict relative" lookup), which applies:
 - in capability mode
 - when performing any *at() lookup relative to a capability

These tests will fail until the *at() code is committed; on my local
instance, with the *at() changes, they all pass.

d6d2cfa24b Only call fdclose() on successfully-opened FDs.
Since kern_openat() now uses falloc_noinstall() and finstall() separately,
there are cases where we could get to cleanup code without ever creating
a file descriptor. In those cases, we should not call fdclose() on FD -1.

a9d2f8d84f Second-to-last commit implementing Capsicum capabilities in the FreeBSD
kernel for FreeBSD 9.0:

Add a new capability mask argument to fget(9) and friends, allowing system
call code to declare what capabilities are required when an integer file
descriptor is converted into an in-kernel struct file *.  With options
CAPABILITIES compiled into the kernel, this enforces capability
protection; without, this change is effectively a no-op.

Some cases require special handling, such as mmap(2), which must preserve
information about the maximum rights at the time of mapping in the memory
map so that they can later be enforced in mprotect(2) -- this is done by
narrowing the rights in the existing max_protection field used for similar
purposes with file permissions.

In namei(9), we assert that the code is not reached from within capability
mode, as we're not yet ready to enforce namespace capabilities there.
This will follow in a later commit.

Update two capability names: CAP_EVENT and CAP_KEVENT become
CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they
represent.

852f933d9d Sync makefs(8) ISO 9660 support with NetBSD:
o cd9960 -> cd9660
o Move inclusion of sys/endian.h from cd9660_eltorito.c to cd9660.h
  since actual user is not cd9660_eltorito.c but iso.h and
  cd9660_eltorito.h.

  Actually, include order/place of sys/endian.h doesn't matter on
  netbsd since it is always included by sys/types.h but it's not
  true on other system.  This should fix cross build breakage on
  freebsd introduced by rev. 1.16 of cd9660_eltorito.c.
  Problem reported and fix suggested on twitter.
o Fix fd leaks in error cases. Found by cppcheck.
o RRIP RE length should be 4, not 0
o Apply fixes for PR bin/44114 (makefs(8) -t cd9660 -o rockridge creates
  corrupted cd9660fs), iso9660_rrip.c part:
  - cd9660_rrip_finalize_node() should check rr_real_parent in node->parent,
    not in node itself in RRIP_PL case
  - cd9660_rrip_initialize_node() should update only node passed as arg
    so handle RRIP_PL in DOTDOT case

  Fixes malformed dotdot entries in deep (more than 8 level) directories
  moved into .rr_moved dir.

  Should be pulled up to netbsd-5.
  (no official ISO has such deep dirs, but cobalt restorecd is affected)
