2018-04-25Move kernel GTP support from ggsn/ to lib/Harald Welte9-148/+151
This way, the IP address / route handling between TUN devices and kernel GTP can be shared, which will provide not only a unified codebase but also a more consistent behavior. This also paves the road for to use kernel GTP from sgsnemu in the future. Related: OS#3214 Change-Id: Ic53a971136edd0d8871fbd6746d7b0090ce3a188
2018-04-25lib/tun: Remove tun_setaddr() API, as everyone is using tun_addaddr() nowHarald Welte2-17/+0

2018-04-25sgsnemu: Convert from tun_setaddr() to tun_addaddr()Harald Welte1-2/+1
This converts the last caller of tun_setaddr() outside of lib/tun.c to use tun_addaddr(). Change-Id: Ia301d6a4ee3d02c1af1c85f2fe1041d3013268b0
2018-04-25ggsn: Don't explicitly use tun_setaddr() API anymoreHarald Welte1-2/+2
tun_addaddr() internally contains a fallback to tun_setaddr() for the first address, so we can unify the API usage a bit and use tun_addaddr() from all call sites Change-Id: I34de003a1a040254bd38b29e48caea34cb0c88d2

2018-04-25lib/tun.c: Generalize tun_{set,add}addr*() functionsHarald Welte1-51/+98
There's nothing really tun-specific about the adding and removing of addresses to network devices. Let's generalize the related code. Change-Id: I139a950dd81a4b1199953be1608cd109a060f562

2018-04-25fix segfault in case of kernel gtp-uHarald Welte1-0/+8
There's a problem during the initial start-up of osmo-ggsn in case of kernel gtp-u: apn->ggsn->gsn is not yet set while parsing the 'apn' nodes from the config file. This member is only set after the last 'apn' node has been parsed at the end of the 'ggsn' node. Closes: OS#3217 Change-Id: I022a5e5ebc1f155e8f94938856d310462f79bbe8

This option was removed in dda21ed7d4a897c9284c69175d0da598598eae40 and the behaviour previously implied by -f has since been the default. Change-Id: Iba13df713af03771739a4feff4b222a0c3352394 Related: OS#3044

2018-03-05configure: add --enable-werrorNeels Hofmeyr1-0/+21
Provide a sane means of adding the -Werror compiler flag. Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"', but that actually *overwrites* all the other CFLAGS we might want to have set. Maintain these exceptions from -Werror: a) deprecation (allow upstream to mark deprecation without breaking builds); b) "#warning" pragmas (allow to remind ourselves of errors without breaking builds) As a last configure step before generating the output files, print the complete CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

2018-02-14sgsnemu: listen param is a host, not an interfacePau Espin Pedrol3-6/+6
This param is parsed by gethostbyname() and it's confusing to document it as an interface, because users will then attempt to pass "lo" to it, which fails. Change-Id: Id8ef0e12ddcaf8bfd199a44de0ba4280f05d4431
2018-02-12sgsnemu: Fix bad ptr during context deallocationPau Espin Pedrol1-2/+2
Older commit switched pdp_t to have an array of 2 peers instead of only one in order to accomodate for ipv4v6 contexts, which can have 2 addresses assigned. The usage of peer field was not updated in sgsnemu accordingly, which means the wrong memory portion was being accessed.

in "createif" mode uplink traffic not forwarding from tun interface into Gn, inside GTP-U. create_pdp_conf get iphash (ipm) with pdp == 0x0 Fix - in create_pdp_conf - instead of casting using already definned iphash in ipset function. Change-Id: Icd58450548b3a47cb933d70a2e3166c067552b2c
2018-02-09sgsnemu: created "pinghost" and "createif" modes for mutual exclusionViktor Tsymbalyuk3-26/+97
No warnings when used options from "pinghost" and "createif" groups in a same time. sgsnemu created tun0 interface and send pings inside G-PDU, but didn't calculate replys. Added options modes to avoid mutual exclusion options. Change-Id: I196df7838212dcddecd64a64a6cba613b6cfced0

2018-01-26ggsn: encaps_tun: Avoid forwarding packet if EUA is unassigned, fix crashPau Espin Pedrol3-13/+47
Check (before forwarding received GTP packets into the tun) if the pdp ctx associated with the packet requested was assigned an EUA of the given IP version. This way we avoid for instance forwarding an IPv6 packet (or sending back a response to a Router Solicitation packet) in case the APN was configured without IPv6 support or if the MS/SGSN didn't ask for an IPv6 while requesting an EUA. As a side effect, this commit fixes an OSMO_ASSERT hit introduced in handle_router_mcast in 2d6a69e69a4b4cb2b8cc63c4810dae44e5a4d8f6 due to a deffective MS sending an icmpv6 Router Solicitation over IPv6 after having been requesting and assigned an IPv4 EUA (so no IPv6 packets expected). Before that commit, there was no crash but the message was being wrongly answered and used an uninitialized .v6 addr field from the peer struct.

2018-01-26sgsnemu: sgsnemu stopped after recieving "Request accepted" from ggsnViktor Tsymbalyuk1-1/+1
"sgsnemu" stopped with the message "Received create PDP context response. Cause value: 128", but normaly at that poit it should continue working and create "user plane". Reason: Funtion "create_pdp_conf" checking result of "in46a_from_eua" and mistakenly returned EOF when more than 1 IP address provided by GGSN. Now function "create_pdp_conf" stopped with error when 0 IP provided or error code comes from "in46a_from_eua".

2017-12-15ggsn_vty.c: Print ipv6 link-local cmd when writing config to filePau Espin Pedrol1-0/+2
Previous commit added the ipv6 link-local vty cmd but forgot to add code to print its value in config_write_apn. Fixes: 37c45e3998fca240b5266abd3ac883d0a35bab50 Change-Id: I08aeaa98d6dc318b7e9740d837ba4ac48cd7051c
2017-12-14ggsn: Add 'ipv6 link-local' vty cmdPau Espin Pedrol3-1/+37
This vty cmd let's you set up a new link-local IP for a specific APN to be used during ICMPv6 Router Advertisement procedure. osmo-ggsn hence requires a link-local IPv6 address to be added to the tun interface, otherwise the apn will not be configured correctly and it won't be able to allocate addresses from the ipv6 pool later on. This feature is useful in case your OS doesn't support autoconfiguring link-local IPs when the interface is brought up (some linux versions are known to fail at this) or in case you configured your OS specifically to avoid automatic set up (sysctl net.ipv6.conf.*.autoconf). If "no ipv6 link-local" is provided (default), osmo-ggsn will rely on the OS or the ipup-script setting up the link-local IP for the tun interface at creation time, then fetching it after ipup-script time and using the first link-local ip found. On the other hand, if the "ipv6 link-local" cmd is provided, osmo-ggsn will add the link-local IP to the interface manually and use that one for later Router Advertisement procedures.

First of all, dstaddr can be NULL, avoid copying it in that case. Second, we want to copy the addr data, not the pointer. I tested it and the IP was not added (not shown in ip addr) until I copied the content instead of the address. Change-Id: I8da637b155f0e913cab6c5b0dde355c9f33375b5
