aed5570872 Complete break-out of sys/sys/mac.h into sys/security/mac/mac_framework.h
begun with a repo-copy of mac.h to mac_framework.h.  sys/mac.h now
contains the userspace and user<->kernel API and definitions, with all
in-kernel interfaces moved to mac_framework.h, which is now included
across most of the kernel instead.

This change is the first step in a larger cleanup and sweep of MAC
Framework interfaces in the kernel, and will not be MFC'd.

33f19bee6f - Conditionalize Giant around VFS operations for ALQ, ktrace, and
generating a coredump as the result of a signal.
- Fix a bug where we could leak a Giant lock if vn_start_write() failed
  in coredump().

e551d45211 Modify the alq(9) alq_open() API to accept a file creation mode, rather
than defaulting the cmode argument to vn_open() to 0.  Supply a default
argument of ALQ_DEFAULT_CMODE (0600) in current callers.

7c89f162bc Add fdidx argument to vn_open() and vn_open_cred() and pass -1 throughout. 2003-07-27 17:04:56 +00:00
Robert Watson
4b090e41ff Add an explicit credential argument to alq_open() to allow the caller to
specify what credential to use when authorizing vn_open() and later
write operations, rather than curthread->td_ucred.

When writing KTR traces to an ALQ, specify the credential of the thread
generating the sysctl request.

30fd5d085d - Reset the free ent to NULL if we have consumed the last free entry. This
fixes a problem where we would overwrite old data if we ran out of free
   entries.

9405072a95 - Add an asynchronous fixed length record logging mechanism called
ALQ (Asynch. Logging Queues).  ALQ supports many seperate queues with
   different record and buffer sizes.  It opens and logs to any vnode so
   it can be used with character devices as well as regular files.
