- BIOCGDIRECTION and BIOCSDIRECTION get or set the setting determining
whether incoming, outgoing, or all packets on the interface should be
returned by BPF. Set to BPF_D_IN to see only incoming packets on the
interface. Set to BPF_D_INOUT to see packets originating locally and
remotely on the interface. Set to BPF_D_OUT to see only outgoing
packets on the interface. This setting is initialized to BPF_D_INOUT
by default. BIOCGSEESENT and BIOCSSEESENT are obsoleted by these but
kept for backward compatibility.
- BIOCFEEDBACK sets packet feedback mode. This allows injected packets
to be fed back as input to the interface when output via the interface is
successful. When BPF_D_INOUT direction is set, injected outgoing packet
is not returned by BPF to avoid duplication. This flag is initialized to
zero by default.
Note that libpcap has been modified to support BPF_D_OUT direction for
pcap_setdirection(3) and PCAP_D_OUT direction is functional now.

Description:
Because of OpenSSL's recently announced vulnerabilities
(CAN-2006-4339, CVE-2006-2937 and CVE-2006-2940) which affect named,
we are announcing this workaround and releasing patches. A proof of
concept attack on OpenSSL has been demonstrated for CAN-2006-4339.
OpenSSL is required to use DNSSEC with BIND.
Fix for version 9.3.2-P1 and lower:
Upgrade to BIND 9.3.2-P2, then generate new RSASHA1 and
RSAMD5 keys for all old keys using the old default exponent
and perform a key rollover to these new keys.
These versions also change the default RSA exponent to be
65537 which is not vulnerable to the attacks described in
CAN-2006-4339.
understand that non-local variables can never be collected, and when
it collected the static variable for mexitcount_libfunc, gcc aborted
on the next use of this variable.
This quick fix is to reinitialize the variable on every use and depend
on garbage collection recovering the small amount of memory wasted by
this, and not worry by the small amount of time wasted by this. It
would be better to initialize the variable together with most of the
other libfuncs in optabs.c and depend on whatever magic is there to
prevent its collection, but we initialize it here to avoid taking at
least 2 more files off the vendor branch.

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.

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.

OpenBSM 1.0 alpha 9
- Rename many OpenBSM-specific constants and API elements containing the
strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true
for almost all existing constants and APIs.
- Instead of passing a per-instance cookie directly into all audit filter
APIs, pass in the audit filter daemon state pointer, which is then used by
the module using an audit_filter_{get,set}cookie() API. This will allow
future service APIs provided by the filter daemon to maintain their own
state -- for example, per-module preselection state.
OpenBSM 1.0 alpha 8
- Correct typo in definition of AUR_INT.
- Adopt OpenSolaris constant values for AUDIT_* configuration flags.
- Arguments to au_to_exec_args() and au_to_exec_env() no longer const.
- Add kernel versions of au_to_exec_args() and au_to_exec_env().
- Fix exec argument type that is printed for env strings from 'arg' to 'env'.
- New OpenBSM token version number assigned, constants added for other
commonly seen version numbers.
- OpenBSM-specific events assigned numbers in the 43xxx range to avoid future
collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they
are now deprecated numberings.
- autoconf now detects clock_gettime(), which is not available on Darwin.
- praudit output fixes relating to arg32 and arg64 tokens.
- Maximum record size updated to 64k-1 to match Solaris record size limit.

- Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close();
previously we used hard-coded 0 and 1 values.
- Add man page for au_open(), au_write(), au_close(), and
au_close_buffer().
- Support a more complete range of data types for the arbitrary data token:
add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias
to AUR_INT), add AUR_INT64.
- Add au_close_token(), which allows writing a single token_t to a memory
buffer. Not likely to be used much by applications, but useful for
writing test tools.
- Modify au_to_file() so that it accepts a timeval in user space, not just
kernel -- this is not a Solaris BSM API so can be modified without
causing compatibility issues.
- Define a new API, au_to_header32_tm(), which adds a struct timeval
argument to the ordinary au_to_header32(), which is now implemented by

gettimeofday(), as it's not needed, and introduces possible failure

- Don't perform byte order transformations on the addr/machine fields of
the terminal ID that appears in the process32/subject32 tokens. These
are assumed to be IP addresses, and as such, to be in network byte
order.
- Universally, APIs now assume that IP addresses and ports are provided
in network byte order. APIs now generally provide these types in
network byte order when decoding.
- Beginnings of an OpenBSM test framework can now be found in openbsm/test.
This code is not built or installed by default.
- auditd now assigns more appropriate syslog levels to its debugging and
error information.
- Support for audit filters introduced: audit filters are dynamically
loaded shared objects that run in the context of a new daemon,
auditfilterd. The daemon reads from an audit pipe and feeds both BSM and
parsed versions of records to shared objects using a module API. This
will provide a framework for the writing of intrusion detection services.
- New utility API, audit_submit(), added to capture common elements of audit
record submission for many applications.

- Update install notes to indicate /etc files are to be installed manually.
- On systems without LOG_SECURITY, use LOG_AUTH.
- Convert to autoconf/automake in order to move to a more portable (not
BSD-specific) build infrastructure, and more easy conditional building of

not have native support for manual symlinks. This will be addressed in a
future OpenBSM release.
- Add compat/queue.h, to be used on systems dated BSD queue macro libraries

- Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the
existing conventions for a CHANGELOG.
- Some private data structures moved from audit.h to audit_internal.h to
prevent inappropriate use by applications and name space pollution.
- Improved detection and use of endian macros using autoconf.
- Avoid non-portable use of struct in6_addr, which is largely opaque.
- Avoid leaking BSD kernel socket related token code to user space in
bsm_token.c.
- Teach System V IPC calls to look for Linux naming variations for certain
struct ipc_perm fields.
- Test for audit system calls, and if not present, don't build
bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on
those system calls.
- au_close() is not implemented on systems that don't have audit system
calls, but au_close_buffer() is.
- Work around missing BSDisms in bsm_wrapper.c.
- Fix nested includes so including libbsm.h in an application on Linux

- Library build fixed on Darwin following include file tweaks. The native
Darwin sys/audit.h conflicts with bsm/audit.h due to duplicate types, so
for now we force bsm_wrappers.c to not perform a nested include of
sys/audit.h.
