| Summary | 0000831: not careful enough when validating uplink parameter in switches.conf causes threads to hang later | |||||||
| Description | in SwitchFactory.pm we accept anything has an uplink: foreach my $_tmp (@_uplink_tmp) { $_tmp =~ s/ //g; push @uplink, $_tmp; } but later down the road we compare uplink in an explicitly numerical way if ( $upLinks[0] == -1 ) { $logger->warn("Can't determine Uplinks for the switch -> do nothing"); we should validate both places at first, only "dynamic" (no matter the case) and arbitrary length digits should be accepted Oct 27 02:02:02 pfcmd(0) INFO: pidof -x pfsetvlan returned 27449 (pf::services::service_ctl) Argument "dynamic" isn't numeric in numeric eq (==) at /usr/local/pf/lib/pf/vlan.pm line 148 (0000001) (W numeric) The indicated string was fed as an argument to an operator that expected a numeric value instead. If you're fortunate the message will identify which operator was so unfortunate. thread failed to start: Can't use string ("0") as a HASH ref while "strict refs" in use at /usr/local/pf/lib/pf/violation.pm line 379 (0000002) (W threads)(S) The entry point function of threads->create() failed for some reason. | |||||||

it would seem that there is already some validation in lib/pf/services.pm |

necessary fix is twofold: 1- test for empty array in vlan.pm at 150, this is only a warning so it'll be done later 2- on startup we do validate what's a good uplink parameter and we stop pfsetvlan if it's not good so I loosed up the check to allow the dynamic keyword in an case-insensitive manner, related to our 809 fix already in place: # # old_revision [2a026176d98198d30d3f66bd404f6145477832f1] # # patch "pf/lib/pf/services.pm" # from [b7bc8368e2acec7bfd1a5e6c488c1a448596eb10] # to [64df13883484a57a3eb337b93bcd357ceca3b57a] # ============================================================ --- pf/lib/pf/services.pm b7bc8368e2acec7bfd1a5e6c488c1a448596eb10 +++ pf/lib/pf/services.pm 64df13883484a57a3eb337b93bcd357ceca3b57a @@ -994,7 +994,7 @@ sub switches_conf_is_valid { my $uplink = $switches_conf{$section}{'uplink'} || $switches_conf{'default'}{'uplink'}; if (( !defined($uplink) ) - || ( ( $uplink ne 'dynamic' ) + || ( ( lc($uplink) ne 'dynamic' ) && ( !( $uplink =~ /(\d+,)*\d+/ ) ) ) ) { |
