2023-11-07luci-lib-ip: fix creating address instances from integersJo-Philipp Wich
Ensure that the proper byte order is used when creating IPv4/IPv6/MAC instances from integer values on big endian systems. Fixes: #6678 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-06luci-lib-ip: fix tolinklocal invalid ipv6 resultSantiago Piccinini
Force zeroing uninitialized memory. Signed-off-by: Santiago Piccinini <spiccinini@altermundi.net>
2020-02-08luci-lib-ip: explicitly clear scope when allocating new userdataJo-Philipp Wich
Fixes: #3609 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-01-23luci-lib-ip: explicitly initialize address scope valueJo-Philipp Wich
Explicitly initialize the address scope value to zero in parse_cidr() and L_setaddr() to avoid stray scope identifiers getting added when formatting the address object as string. Fixes: 1d2b4c777 ("luci-lib-ip: support scoped IPv6 addresses") Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2015-01-28luci-lib-ip: add functions to deal with IPv6 mapped IPv6Jo-Philipp Wich
* Add luci.ip.cidr.is6mapped4() to test whether an IPv6 CIDR is a mapped IPv4 one * Add luci.ip.cidr.mapped4() to derive IPv4 from mapped CIDR * Remove mapped IPv4 workaround from constructor as it breaks genuine addrs like ::ffff:0 Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
2015-01-28luci-lib-ip: multiple fixesJo-Philipp Wich
* Fix broken neighbor filtering by address range due to uninitialized memory * Fix wrong sizeof in _cidr_add_sub when adding/substracing IPv6 addresses * Properly convert numeric values to IPv6 addresses Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
2015-01-26luci-lib-ip: accept 2nd netmask argument in new(), IPv4() and IPv6()Jo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
2015-01-25luci-lib-ip: fix segfault in link() on systems with ip6gre supportJo-Philipp Wich
If an ip6gre interface is queried, the resulting link local address string of 47 byte overflowed the buffer of 32 bytes used to hold the translated address. Increase the address string buffer to 48 byte and check the address length prior to writing it into the buffer to avoid future problems with longs link local addresses.

2015-01-22luci-lib-ip: fix routes() for non-callback invocationsJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
2015-01-22libs: add luci-lib-ipJo-Philipp Wich
Add new luci.ip library which is an api compatible C reimplementation of ip.lua. It also supports dumping the system routing table and neighbour entry database via netlink. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
