7493f24ee6 - Implement two new system calls:
int bindat(int fd, int s, const struct sockaddr *addr, socklen_t addrlen);
	int connectat(int fd, int s, const struct sockaddr *name, socklen_t namelen);

  which allow to bind and connect respectively to a UNIX domain socket with a
  path relative to the directory associated with the given file descriptor 'fd'.

- Add manual pages for the new syscalls.

- Make the new syscalls available for processes in capability mode sandbox.

- Add capability rights CAP_BINDAT and CAP_CONNECTAT that has to be present on
  the directory descriptor for the syscalls to work.

- Update audit(4) to support those two new syscalls and to handle path
  in sockaddr_un structure relative to the given directory descriptor.

- Update procstat(1) to recognize the new capability rights.

- Document the new capability rights in cap_rights_limit(2).

2609222ab4 Merge Capsicum overhaul:
- Capability is no longer separate descriptor type. Now every descriptor
  has set of its own capability rights.

- The cap_new(2) system call is left, but it is no longer documented and
  should not be used in new code.

- The new syscall cap_rights_limit(2) should be used instead of
  cap_new(2), which limits capability rights of the given descriptor
  without creating a new one.

- The cap_getrights(2) syscall is renamed to cap_rights_get(2).

- If CAP_IOCTL capability right is present we can further reduce allowed
  ioctls list with the new cap_ioctls_limit(2) syscall. List of allowed
  ioctls can be retrived with cap_ioctls_get(2) syscall.

- If CAP_FCNTL capability right is present we can further reduce fcntls
  that can be used with the new cap_fcntls_limit(2) syscall and retrive
  them with cap_fcntls_get(2).

- To support ioctl and fcntl white-listing the filedesc structure was
  heavly modified.

- The audit subsystem, kdump and procstat tools were updated to
  recognize new syscalls.

- Capability rights were revised and eventhough I tried hard to provide
  backward API and ABI compatibility there are some incompatible changes
  that are described in detail below:

	CAP_CREATE old behaviour:
	- Allow for openat(2)+O_CREAT.
	- Allow for linkat(2).
	- Allow for symlinkat(2).
	CAP_CREATE new behaviour:
	- Allow for openat(2)+O_CREAT.

	Added CAP_LINKAT:
	- Allow for linkat(2). ABI: Reuses CAP_RMDIR bit.
	- Allow to be target for renameat(2).

	Added CAP_SYMLINKAT:
	- Allow for symlinkat(2).

	Removed CAP_DELETE. Old behaviour:

	- Allow to be source for renameat(2).

	Removed CAP_RMDIR. Old behaviour:
	- Allow for unlinkat(2) when removing directory.

	Added CAP_RENAMEAT:
	- Required for source directory for the renameat(2) syscall.

	Added CAP_UNLINKAT (effectively it replaces CAP_DELETE and CAP_RMDIR):
	- Allow for unlinkat(2) on any object.
	- Required if target of renameat(2) exists and will be removed by this
	  call.

	Removed CAP_MAPEXEC.

	CAP_MMAP old behaviour:
	- Allow for mmap(2) with any combination of PROT_NONE, PROT_READ and
	  PROT_WRITE.

	- Disallow read(2), readv(2) (if there is no CAP_SEEK).
	CAP_READ new behaviour:
	- Allow read(2), readv(2).

a66ffea41d When we are waiting for new trail files we may have been disconnected and
reconnected in the meantime. Check if reset is set before opening next trail
file, as not doing so will result in sending OPEN message with the same
file name twice and this is illegal - the second OPEN is send without first
closing previous trail file.

OpenBSM 1.1

- Change auditon(2) parameters and data structures to be 32/64-bit architecture
  independent.  Add more information to man page about auditon(2) parameters.
- Add wrapper functions for auditon(2) to use legacy commands when the new
  commands are not supported.
- Add default for 'expire-after' in audit_control to expire trail files when
  the audit directory is more than 10 megabytes ('10M').
- Interface to convert between local and BSM fcntl(2) command values has been
  added:  au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
  definitions of constants in audit_fcntl.h.
- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
  generated by audit_submit(3) were improperly encoded has been fixed.
- Fix example in audit_submit(3) man page.  Also, make it clear that we want
  the audit ID as the argument.
- A new audit event class 'aa', for post-login authentication and
  authorization events, has been added.

OpenBSM 1.1 beta 1

- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
  Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
  For legacy support no suffix defaults to bytes.
- Audit trail log expiration support added.  It is configured in
  audit_control(5) with the expire-after parameter.  If there is no
  expire-after parameter in audit_control(5), the default, then the audit
  trail files are not expired and removed.  See audit_control(5) for
  more information.
- Change defaults in audit_control: warn at 5% rather than 20% free for audit
  partitions, rotate automatically at 2mb, and set the default policy to
  cnt,argv rather than cnt so that execve(2) arguments are captured if
  AUE_EXECVE events are audited.  These may provide more usable defaults for
  many users.
- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
  au_to_socket_ex(3) arguments to BSM format.
- Fix error encoding AUT_IPC_PERM tokens.

OpenBSM 1.1 alpha 5

- Stub libauditd(3) man page added.
- All BSM error number constants with BSM_ERRNO_.
- Interfaces to convert between local and BSM socket types and protocol
  families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
  au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
  of constants in audit_domain.h and audit_socket_type.h.  This improves
  interoperability by converting local constant spaces, which vary by OS, to
  and from Solaris constants (where available) or OpenBSM constants for
  protocol domains not present in Solaris (a fair number).  These routines
  should be used when generating and interpreting extended socket tokens.
- Fix build warnings with full gcc warnings enabled on most supported
  platforms.
- Don't compile error strings into bsm_errno.c when building it in the kernel
  environment.
- When started by launchd, use the label com.apple.auditd rather than
  org.trustedbsd.auditd.

OpenBSM 1.1 alpha 4

- With the addition of BSM error number mapping, we also need to map the
  local error number passed to audit_submit(3) to a BSM error number,
  rather than have the caller perform that conversion.
- Reallocate user audit events to avoid collisions with Solaris; adopt a
  more formal allocation scheme, and add some events allocated in Solaris
  that will be of immediate use on other platforms.
- Add an event for Calife.
- Add au_strerror(3), which allows generating strings for BSM errors
  directly, rather than requiring applications to map to the local error
  space, which might not be able to entirely represent the BSM error
  number space.
- Major auditd rewrite for launchd(8) support.  Add libauditd library
  that is shared between launchd and auditd.
- Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for
  (re)starting auditing under launchd(8) on Mac OS X.
- Add 'current' symlink to active audit trail.
- Add crash recovery of previous audit trail file when detected on audit
  startup that it has not been properly terminated.
- Add the event AUE_audit_recovery to indicated when an audit trail file
  has been recovered from not being properly terminated.  This event is
  stored in the new audit trail file and includes the path of recovered
  audit trail file.
- Mac OS X and FreeBSD dependent code in auditd.c is separated into
  auditd_darwin.c and auditd_fbsd.c files.
- Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system
  calls.
- For Mac OS X, we use ASL(3) instead of syslog(3) for logging.
- Add support for NOTICE level logging.

OpenBSM 1.1 alpha 3

- Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map
  between BSM error numbers (largely the Solaris definitions) and local
  errno(2) values for 32-bit and 64-bit return tokens.  This is required
  as operating systems don't agree on some of the values of more recent
  error numbers.
- Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the
  total size for the token.  This buge.
- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

OpenBSM 1.1 alpha 2

- Include files in OpenBSM are now broken out into two parts: library builds
  required solely for user space, and system includes, which may also be
  required for use in the kernels of systems integrating OpenBSM.  Submitted
  by Stacey Son.
- Configure option --with-native-includes allows forcing the use of native
  include for system includes, rather than the versions bundled with OpenBSM.
  This is intended specifically for platforms that ship OpenBSM, have adapted
  versions of the system includes in a kernel source tree, and will use the
  OpenBSM build infrastructure with an unmodified OpenBSM distribution,
  allowing the customized system includes to be used with the OpenBSM build.
  Submitted by Stacey Son.
- Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s
  or asprintf().  Added compat/strlcpy.h for Linux.
- Remove compatibility defines for old Darwin token constant names; now only
  BSM token names are provided and used.
- Add support for extended header tokens, which contain space for information
  on the host generating the record.
- Add support for setting extended host information in the kernel, which is
  used for setting host information in extended header tokens.  The
  audit_control file now supports a "host" parameter which can be used by
  auditd to set the information; if not present, the kernel parameters won't
  be set and auditd uses unextended headers for records that it generates.

OpenBSM 1.1 alpha 1

- Add option to auditreduce(1) which allows users to invert sense of
  matching, such that BSM records that do not match, are selected.
- Fix bug in audit_write() where we commit an incomplete record in the
  event there is an error writing the subject token.  This was submitted
  by Diego Giagio.
- Build support for Mac OS X 10.5.1 submitted by Eric Hall.
- Fix a bug which resulted in host XML attributes not being arguments so
  that const strings can be passed as arguments to tokens.  This patch was
  submitted by Xin LI.
- Modify the -m option so users can select more then one audit event.
- For Mac OS X, added Mach IPC support for audit trigger messages.
- Fixed a bug in getacna() which resulted in a locking problem on Mac OS X.
- Added LOG_PERROR flag to openlog when -d option is used with auditd.
- AUE events added for Mac OS X Leopard system calls.

history notes since the last import:

OpenBSM 1.0 alpha 12

- Correct bug in auditreduce which prevented the -c option from working
  correctly when the user specifies to process successful or failed events.
  The problem stemmed from not having access to the return token at the time
  the initial preselection occurred, but now a second preselection process
  occurs while processing the return token.
- getacfilesz(3) API added to read new audit_control(5) filesz setting,
  which auditd(8) now sets the kernel audit trail rotation size to.
- auditreduce(1) now uses stdin if no file names are specified on the command
  line; this was the documented behavior previously, but it was not
  implemented.  Be more specific in auditreduce(1)'s examples section about
  what might be done with the output of auditreduce.
- Add audit_warn(5) closefile event so that administrators can hook
  termination of an audit trail file.  For example, this might be used to
  compress the trail file after it is closed.
- auditreduce(1) now uses regular expressions for pathname matching. Users can
  now supply one or more (comma delimited) regular expressions for searching
  the pathnames. If one of the regular expressions is prefixed with a tilde
  (~), and a path matches, it will be excluded from the search results.

bb97b41819 Vendor import of OpenBSM 1.0 alpha 11, with the following change history
notes since the last import:

OpenBSM 1.0 alpha 11

- Reclassify certain read/write operations as having no class rather than the
  fr/fw class; our default classes audit intent (open) not operations (read,
  write).
- Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads
  and writes of sysctls as separate events.  Add additional kernel
  environment and jail events for FreeBSD.
- Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER
  (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued
  by the kernel audit implementation) so that they can be distinguished.
- Disable rate limiting of rotate requests; as the kernel doesn't retransmit
  a dropped request, the log file will otherwise grow indefinitely if the
  trigger is dropped.
- Improve auditd debugging output.
- Fix a number of threading related bugs in audit_control file reading
  routines.
- Add APIs au_poltostr() and au_strtopol() to convert between text
  representations of audit_control policy flags and the flags passed to
  auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY).
- Add API getacpol() to return the 'policy:' entry from audit_control, an
  extension to the Solaris file format to allow specification of policy
  persistent flags.
- Update audump to print the audit_control policy field.
- Update auditd to read the audit_control policy field and set the kernel
  policy to match it when configuring/reconfiguring.  Remove the -s and -h
  arguments as these policies are now set via the configuration file.  If a
  policy line is not found in the configuration file, continue with the
  current default of setting AUDIT_CNT.
- Fix bugs in the parsing of large execve(2) arguments and environmental
  variable tokens; increase maximum parsed argument and variable count.
- configure now detects strlcat(), used by policy-related functions.
- Reference token and record sample files added to test tree.

fdb4472c92 Vendor import of OpenBSM 1.0 alpha 10, with the following changes:
- auditd now generates complete audit records for its events, as required for
  application-submitted audit records in the the FreeBSD kernel audit
  implementation.

This also restores contrib/openbsm/bsm/audit_record to the vendor version
after the build fixes previously committed; however, this file is not used
in the build.

functions are in sync between the kernel and user space.

This restores bsm_token.c as found in OpenBSM 1.0 alpha 9.

8379353c85 Remove duplicated include files from HEAD that appear in both
contrib/openbsm/bsm and sys/bsm.  This will help avoid triggering
problems due to an inconsistent include order between the base and
lib32 builds.  We will continue to import these files on the vendor
branch.  Files used purely in user space (audit_uevents.h) are not
removed.

58178f6693 Import on vendor branch two files that have been tweaked to unbreak
the build.  The openbsm folks are free to fix it in any other way they
see fit once they resurface.

Basically, make everything always be const char **, even though const
char ** usually should be 'const char * const *' in most cases.  This
makes the three different definitions consistant and allows world to
build.
