From dd906398dd0aa8582bdba519a2026278359c2888 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 24 Jun 2015 13:27:34 +0200 Subject: sd-netlink: don't export internal type-system details The kernel bonding layer allows passing an array of ARP IP targets as bond-configuration. Due to the weird implementation of arrays in netlink (which we haven't figure out a generic way to support, yet), we usually hard-code the supported array-sizes. However, this should not be exported from sd-netlink. Instead, make sure the caller just uses it's current hack of enumerating the types, and the sd-netlink core will have it's own list of supported array-sizes (to be removed in future extensions, btw!). If either does not match, we will just return a normal error. Note that we provide 2 constants for ARP_IP_TARGETS_MAX now. However, both have very different reasons: - the constant in netdev-bond.c is used to warn the user that the given number of targets might not be supported by the kernel (even though the kernel might increase that number at _any_ time) - the constant in sd-netlink is solely used due to us missing a proper array implementation. Once that's supported in the type-system, it can be removed without notice Last but not least, this patch turns the log_error() into a log_warning(). Given that the previous condition was off-by-one, anyway, it never hit at the right time. Thus, it was probably of no real use. --- src/libsystemd/sd-netlink/netlink-types.h | 22 ---------------------- 1 file changed, 22 deletions(-) (limited to 'src/libsystemd/sd-netlink/netlink-types.h') diff --git a/src/libsystemd/sd-netlink/netlink-types.h b/src/libsystemd/sd-netlink/netlink-types.h index b1ef7af421..a210163241 100644 --- a/src/libsystemd/sd-netlink/netlink-types.h +++ b/src/libsystemd/sd-netlink/netlink-types.h @@ -90,25 +90,3 @@ typedef enum NLUnionLinkInfoData { const char *nl_union_link_info_data_to_string(NLUnionLinkInfoData p) _const_; NLUnionLinkInfoData nl_union_link_info_data_from_string(const char *p) _pure_; - -/* Maximum ARP IP target defined in kernel */ -#define BOND_MAX_ARP_TARGETS 16 - -typedef enum BondArpTargets { - BOND_ARP_TARGETS_0, - BOND_ARP_TARGETS_1, - BOND_ARP_TARGETS_2, - BOND_ARP_TARGETS_3, - BOND_ARP_TARGETS_4, - BOND_ARP_TARGETS_5, - BOND_ARP_TARGETS_6, - BOND_ARP_TARGETS_7, - BOND_ARP_TARGETS_8, - BOND_ARP_TARGETS_9, - BOND_ARP_TARGETS_10, - BOND_ARP_TARGETS_11, - BOND_ARP_TARGETS_12, - BOND_ARP_TARGETS_13, - BOND_ARP_TARGETS_14, - BOND_ARP_TARGETS_MAX = BOND_MAX_ARP_TARGETS, -} BondArpTargets; -- cgit v1.2.3-54-g00ecf
