Some Veriexec stuff that's been rotting in my tree for months.
Bug fixes:
- Fix crash reported by Scott Ellis on current-users@.
- Fix race conditions in enforcing the Veriexec rename and remove
policies. These are NOT security issues.
- Fix memory leak in rename handling when overwriting a monitored
file.
- Fix table deletion logic.
- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.
All relevant man-pages were updated to reflect the above changes.
Binary compatibility with existing veriexecctl binaries is maintained.

Some Veriexec stuff that's been rotting in my tree for months.
Bug fixes:
- Fix crash reported by Scott Ellis on current-users@.
- Fix race conditions in enforcing the Veriexec rename and remove
policies. These are NOT security issues.
- Fix memory leak in rename handling when overwriting a monitored
file.
- Fix table deletion logic.
- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.
All relevant man-pages were updated to reflect the above changes.
Binary compatibility with existing veriexecctl binaries is maintained.

Some Veriexec stuff that's been rotting in my tree for months.
Bug fixes:
- Fix crash reported by Scott Ellis on current-users@.
- Fix race conditions in enforcing the Veriexec rename and remove
policies. These are NOT security issues.
- Fix memory leak in rename handling when overwriting a monitored
file.
- Fix table deletion logic.
- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.
All relevant man-pages were updated to reflect the above changes.

Some Veriexec stuff that's been rotting in my tree for months.
Bug fixes:
- Fix crash reported by Scott Ellis on current-users@.
- Fix race conditions in enforcing the Veriexec rename and remove
policies. These are NOT security issues.
- Fix memory leak in rename handling when overwriting a monitored
file.
- Fix table deletion logic.
- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.

okay, since there was no way to divide this to two commits, here it goes..
introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.
this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.
as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.
also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.
tons of input from yamt@, wrstuden@, martin@, and christos@.

- Don't prevent query requests if not in learning mode.
KPI updates:
- fileassoc_table_run() now takes a cookie to pass to the callback.
- veriexec_table_add() was removed, it is now done internally. As a
result, there's no longer a need for VERIEXEC_TABLESIZE.
- veriexec_report() was removed, it is now internal.
- Perform sanity checks on the entry type, and enforce default type
in veriexec_file_add() rather than in veriexecctl.
- Add veriexec_flush(), used to delete all Veriexec tables, and
veriexec_dump(), used to fill an array with all Veriexec entries.
New features:
- Add a '-k' flag to veriexecctl, to keep the filenames in the kernel
database. This allows Veriexec to produce slightly more accurate
logs under certain circumstances. In the future, this can be either
replaced by vnode->pathname translation, or combined with it.
- Add a VERIEXEC_DUMP ioctl, to dump the entire Veriexec database.
This can be used to recover a database if the file was lost.
Example usage:
# veriexecctl dump > /etc/signatures
Note that only entries with the filename kept (that is, were loaded
with the '-k' flag) will be dumped.
Idea from Brett Lymn.
- Add a VERIEXEC_FLUSH ioctl, to delete all Veriexec entries. Sample
usage:
# veriexecctl flush
- Add a 'veriexec_flags' rc(8) variable, and make its default have
the '-k' flag. On systems using the default signatures file
(generaetd from running 'veriexecgen' with no arguments), this will
use additional 32kb of kernel memory on average.
- Add a '-e' flag to veriexecctl, to evaluate the fingerprint during
load. This is done automatically for files marked as 'untrusted'.
Misc. stuff:
- The code for veriexecctl was massively simplified as a result of
eliminating the need for VERIEXEC_TABLESIZE, and now uses a single
pass of the signatures file, making the loading somewhat faster.
- Lots of minor fixes found using the (still under development)
Veriexec regression testsuite.
- Some of the messages Veriexec prints were improved.
- Various documentation fixes.
All relevant man-pages were updated to reflect the above changes.
Binary compatibility with existing veriexecctl binaries is maintained.

okay, since there was no way to divide this to two commits, here it goes..
introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.
this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.
as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.
also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.
tons of input from yamt@, wrstuden@, martin@, and christos@.
