| # $Title: dwatch(8) module for fchmod(2) entry $ | |||||
| # $Copyright: 2014-2017 Devin Teske. All rights reserved. $ | |||||
| # $FreeBSD$ | |||||
| # | |||||
| ############################################################ DESCRIPTION | |||||
| # | |||||
| # Print arguments being passed to fchmod(2) | |||||
| # | |||||
| ############################################################ PROBE | |||||
| # This is optional, if you don't set or it is NULL, dwatch(8) will try to | |||||
| # dynamically determine the probe via the module's filename. For example, if | |||||
| # the module file is named `foo' then dwatch(8) will try `dtrace -ln foo:entry' | |||||
| # to determine an appropriate probe for watching `foo'. | |||||
| PROBE=syscall::fchmod | |||||
| ############################################################ ACTIONS | |||||
| # Optional actions to be performed before hitting the final print action | |||||
| #exec 9<<EOF | |||||
| #EOF | |||||
| #ACTIONS=$( cat <&9 ) | |||||
| #ID= | |||||
| ############################################################ PRINT ACTION | |||||
| # The default value is simply `entry'. This is paired with $PROBE (which can be | |||||
| # auto-probed when unset or NULL) and can be customized to include clauses for | |||||
| # the final print action which must be true before the print action will run. | |||||
| #PRINT= | |||||
| ############################################################ EVENT TAG | |||||
| # The EVENT_TAG is run inside the print action after the timestamp has been | |||||
| # printed. By default, `UID.GID CMD[PID]: ' of the process is printed. | |||||
| #exec 9<<EOF | |||||
| #EOF | |||||
| #EVENT_TAG=$( cat <&9 ) | |||||
| ############################################################ DETAILS | |||||
| # The DETAILS are run after the EVENT_TAG and by default, the program name and | |||||
| # arguments of the process hitting the PRINT action are shown. This can be | |||||
| # customized to call-specific information because the `-v' flag of dwatch(8) | |||||
| # can provide detailed process information for the PRINT action on lines below | |||||
| # the DETAILS. | |||||
| # | |||||
| # NB: Should produce a single-line and not print a trailing newline. | |||||
| exec 9<<EOF | |||||
| printf("fchmod(fd %i, mode %04o)", (int)arg0, (mode_t)arg1); | |||||
| EOF | |||||
| DETAILS=$( cat <&9 ) | |||||
