The protocol used here is a ++ * strict subset of CDC Ethernet, with three basic differences reflecting ++ * the goal that almost any hardware should run it: ++ * ++ * - Minimal runtime control: one interface, no altsettings, and ++ * no vendor or class specific control requests. If a device is ++ * configured, it is allowed to exchange packets with the host. ++ * Fancier models would mean not working on some hardware. ++ * ++ * - Minimal manufacturing control: no IEEE "Organizationally ++ * Unique ID" required, or an EEPROMs to store one. Each host uses ++ * one random "locally assigned" Ethernet address instead, which can ++ * of course be overridden using standard tools like "ifconfig". ++ * (With 2^46 such addresses, same-net collisions are quite rare.) ++ * ++ * - There is no additional framing data for USB. Packets are written ++ * exactly as in CDC Ethernet, starting with an Ethernet header and ++ * terminated by a short packet. However, the host will never send a ++ * zero length packet; some systems can't handle those robustly. ++ * ++ * Anything that can transmit and receive USB bulk packets can implement ++ * this protocol. That includes both smart peripherals and quite a lot ++ * of "host-to-host" USB cables (which embed two devices back-to-back). ++ * ++ * Note that although Linux may use many of those host-to-host links ++ * with this "cdc_subset" framing, that doesn't mean there may not be a ++ * better approach. Handling the "other end unplugs/replugs" scenario ++ * well tends to require chip-specific vendor requests. Also, Windows ++ * peers at the other end of host-to-host cables may expect their own ++ * framing to be used rather than this "cdc_subset" model. ++ */ ++ ++#if defined(CONFIG_USB_EPSON2888) || defined(CONFIG_USB_ARMLINUX) ++/* PDA style devices are always connected if present */ ++static int always_connected (struct usbnet *dev) ++{ ++ return 0; ++} ++#endif ++ ++#ifdef CONFIG_USB_ALI_M5632 ++#define HAVE_HARDWARE ++ ++/*------------------------------------------------------------------------- ++ * ++ * ALi M5632 driver ... does high speed ++ * ++ * NOTE that the MS-Windows drivers for this chip use some funky and ++ * (naturally) undocumented 7-byte prefix to each packet, so this is a ++ * case where we don't currently interoperate.

If new values are added we need to check first if those are set in every line to avoid any undefined behaviour. A wrong comparison parameter was used which caused that the limit feature was never enabled in the rule generation. ----------------------------------------------------------------------- Summary of changes: config/firewall/rules.pl | 12 ++++++------ config/rootfiles/core/86/filelists/files | 1 + 2 files changed, 7 insertions(+), 6 deletions(-) Difference in files: diff --git a/config/firewall/rules.pl b/config/firewall/rules.pl index 75a9357..a475e2d 100755 --- a/config/firewall/rules.pl +++ b/config/firewall/rules.pl @@ -280,7 +280,7 @@ sub buildrules { # Concurrent connection limit my @ratelimit_options = (); - if (($elements gt 34) && ($$hash{$key}[32] eq 'ON')) { + if (($elements ge 34) && ($$hash{$key}[32] eq 'ON')) { my $conn_limit = $$hash{$key}[33]; if ($conn_limit ge 1) { @@ -296,13 +296,13 @@ sub buildrules { } # Ratelimit - if (($elements gt 37) && ($$hash{$key}[34] eq 'ON')) { + if (($elements ge 37) && ($$hash{$key}[34] eq 'ON')) { my $rate_limit = "$$hash{$key}[35]/$$hash{$key}[36]"; - if ($rate_limit) { - push(@ratelimit_options, ("-m", "limit")); - push(@ratelimit_options, ("--limit", $rate_limit)); - } + if ($rate_limit) { + push(@ratelimit_options, ("-m", "limit")); + push(@ratelimit_options, ("--limit", $rate_limit)); + } } # Check which protocols are used in this rule and so that we can diff --git a/config/rootfiles/core/86/filelists/files b/config/rootfiles/core/86/filelists/files index 63b9c5c..dcdb65c 100644 --- a/config/rootfiles/core/86/filelists/files +++ b/config/rootfiles/core/86/filelists/files @@ -1,6 +1,7 @@ etc/system-release etc/issue opt/pakfire/etc/pakfire.conf +usr/lib/firewall/rules.pl usr/local/bin/update-bootloader var/ipfire/header.pl var/ipfire/langs hooks/post-receive -- IPFire 2.x development tree
