2018-08-07ipacm: send all IPv6 framents to IPA appsMohammed Javid
In case of TCP, if the ipv6 packets are fragmented there is a possibility that the second fragment packets match TCP SYN/FIN/RST rules and packets are routed to apps. This results in connection failure as the primary fragment will be routed correctly to hotspot client. Change-Id: I482b48c4786bda180b6f5d921149fed766c91fe0
2017-10-20ipacm: Add flag -Wall -Werror and fix warningsMohammed Javid

2017-09-12ipacm: fix the v6-offload issue on AndroidSkylar Chang
Remove the check on how many ipv6 addresses are received from modem interface, fix the client prefix comparison logic which contradicts with MDM requirement to only offload tethered-clients who has same prefix as modem interface. Change-Id: Ib4b2f9e67f5c92021956c3ecb963cfed7f016959
2017-08-21IPACM: Support Dual embedded & rmnet callSkylar Chang
Change DL TCP SYNC/RST/FIN ipv6 filter rules to meta-data based rules to avoid DL tcp v6 SYNC-ack back to AP in rmnet-call. Change-Id: I34b56e2bc008e744d7685ae8774705e597952960
2017-07-22IPACM: handle the timing issue on upstream_delSkylar Chang
When CNE send upstream_del event to IPACM after tethered iface down, WAN instance is unable to clean up its v4/v6 tethered list. Add the support to handle this timing issue. Change-Id: I7601c70749e0cd30ef951c99d2ea601ecc4c9201
2017-05-12IPACM: Add support on IPACM-HAL for Android-OSkylar Chang

2016-08-26IPACM: adjust ip type maintenance logicSkylar Chang
Adjust the maintenance logic of interface ip type so that IPACM won't fail to install IPv6 default filtering rules. Change-Id: I1955d991633e0f7d88964e1a47e5c00b7df134b1 Acked-by: Shihuan Liu <shihuanl@qti.qualcomm.com> Signed-off-by: Skylar Chang <chiaweic@codeaurora.org>
2016-08-23ipacm: changes related to IP PasshthroughSridhar Ancha
In IP passthrough, WAN interface will be assigned a private ip address. NAT rules related this IP need to be added to the HW so that there will not be any exceptions. Give provision in XML using which QCMAP indicates passthrough mode. Whenever passthrough mode is enabled and the private ip matches with wan ip, nat rules will be added to the HW.

2016-04-11IPACM: add ethernet header for ipv6 DL trafficSkylar Chang
In AP+STA/CRADLE modes, the catch-up DL routing rule will not retain the header for ipv6 traffic and be dropped on kernel. The fix is to use hdr_proc_context to add the ethernet header to make SW-path working Change-Id: I415c28c70066bbe97217200e26b7282cf5ee2761

2015-10-12IPACM: Fix to clean up default LL routesRavinder Konka
When IPv4 only call is brought up, interface will still have v6 LL address and we go ahead and add default routes. When the call is torn down, we do not clean this as there is no global v6 address. Make a change to clean default LL routes in this case. Change-Id: I7e203aa82a03351cb94f65ea89fa57bd3f1059a9
2015-10-08IPACM: Fix the UL traffic taking SW-exceptionSkylar Chang
When LTE comes first with usb/wlan-tethering enable lately from android UI, IPACM failed to add modem UL filter rules if it's getting UPSTREAM_add event from CNE earlier then the usb/wlan netdev creation event from netlink. The fix is to handle this timing issue. Change-Id: I6452c1bb880bcaec2232784b117e22a2d12c6e8f

2015-09-29IPACM: Fix the ipv6-only AP+STA use-caseSkylar Chang
For ipv6-only AP+STA, SoftAP won't posting v6 default route event to IPACM because of its new feature called priority backhaul. Therefore IPACM needs to listen for RTPROT_RA netlink event instead to find the externel AP's mac and construct the full wlan header.

2015-05-18IPACM: Add support for Ethernet bridge ModeSkylar Chang
In ethernet bridge mode, all data traffics are routed directly to modem via IPA HW path from ethernet client and vice-versa. To support, IPACM installs modem uplink and downlink rules with action PASS_TO_ROUTING. Change-Id: Ia743d86e0480528021c4c62025f91df29d09ec38

2015-02-17IPACM : Add support for the XLAT featureSkylar Chang
IPA needs to support modem CLAT feature which translates ipv4 traffic to ipv6 and vice-versa. In order to acheive this, IPACM needs configure CLAT/XLAT rules if the embedded PDN is CLAT PDN, otherwise it should construct the rules for normal internet PDN.interface Change-Id: Ia0ce20fbe0463cb5ac6d25a066be4c50c0303da2

2015-02-03IPACM: support external-AP running bridge modeSkylar Chang
To support MTP running as AP+STA mode and connect to external-AP which is running as bridge mode, IPACM needs to construct the ethernet header by using the mac-addr which matched the default gw IP instead of directly using external-ap's MAC via wlan-driver sent.

2015-01-14IPACM: fix external AP switch issueSkylar Chang
When device keep switching between external AP1 and AP2, sometimes getifaddrs API returns old ipv4 of STA iface which causes IPACM passing the wrong wan-ip for IPANAT tbl. The fix is to wait netlink socket to tell IPACM the updated STA iface ipv4-addr. Change-Id: I000e45f10dcb726059f6c161b4514a128ed7754c

In AP+STA mode, usb-client can download FTP if FTP server outside the subnet of external AP. However if the FTP server is insided the same subnet as external-AP, the FTP download will failed, also TCP UL/DL is not working properly. The fix is to construct headers/routing rules for each wifi-client which is connected to the same external AP's subnet. Change-Id: I839d33d34b4fd544381b9cf7bd2ba20b51a17551

2014-07-01IPACM: Fix end2end ipv6 ping issueSkylar Chang
Identify the root-cause of end2end ipv6 ping issue is because the NS/NA packets are not retaining the ethernet header when RT miss go Apps in AP+STA mode or ecm-backhaul cradle mode. The fix is to add icmpv6 filter rule on wan RX endpoint when device is in AP+STA or cradle ecm-backhaul mode. Change-Id: I1c763b38b9ec524c35f381e59dd0ca5cefaf1f7c

2014-05-21IPACM: support usb dynamic config w.o plug-in/outSkylar Chang
In order to support dynamically change from ecm-thethering to ecm-backhaul without usb-cable plug-in/plug-out, IPACM needs to propagate configuration change event to all ifaces and each iface will clean/delete its own rules if its category is changed and open a new instance to install the new routing/filtering rules.
