* libsysutils: SocketListener export releaseMark Salyzyn2014-01-271-0/+3
| | | | | | | | | | | | * Foreground thread (legacy) closes connection by reporting false return value for onDataAvailable. * Background thread can choose instead to close the connection asynchronously by calling release, must return true for the onDataAvailable method. (cherry picked from commit d7ad4e409eaac53db3a9789060097b712850b337) Change-Id: I70ab37d5c22b02804aa3b4dfb26cc9b75291f8b6
* libsysutils: Add iovec/runOnEachSocketMark Salyzyn2014-01-273-13/+48
| | | | | | | | | | | | | | | | | | | | SocketClient: * Replace sendDataLocked with sendDataLockedv which takes an iovec. * Add a version of sendData, sendDatav, which takes an iovec. * do not preserve iovec content through sendDatav SocketListener: * Add runOnEachSocket, which allows to to specify a SocketClientCommand to run individually on each socket. This allows you to do broadcast-like actions customized for each individual socket. * Client safe list reference counting for sendBroadcast & runOnEach Socket (cherry picked from commit a6e965578e44f8ae5f98de822ba5decec381d5fc) Signed-off-by: Nick Kralevich <nnk@google.com> Signed-off-by: Mark Salyzyn <salyzyn@google.com> Change-Id: I716f89c01b4cb7af900045c7e41fac1492defb06

* | Support parsing RDNSS ND options from netlink.Lorenzo Colitti2013-11-201-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The RDNSS options (RFC 6106) used to configure DNS servers via router advertisements are passed from the kernel to userspace via RTM_NEWNDUSEROPT netlink messages. Add code to NetlinkEvent to parse them. Also fix a compiler warning and a couple of style issues.

* | Switch back to subsystem "net" for netlink events.Lorenzo Colitti2013-11-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change to enable address tracking via netlink incorrectly changed the subsystem of rtnetlink events from "net" to "interface". This broke interface add/delete notifications, which come from the kernel with subsystem "net". Switch back to "net" and deal with address tracking via new action codes instead of a new subsystem.

* | Parse IP address changes in NetlinkEvent.Lorenzo Colitti2013-11-201-0/+1
|/ | | | | | | | | | | | | | | This adds support for parsing RTM_NEWADDR and RTM_DELADDR netlink messages received on netd's netlink socket and formatting them them so NetlinkHandler can process them. Address changes are notified in subsystem "address". Interface changes, which used to be notified in subsystem "net", are now notified in subsystem "interface" to avoid confusion.

| | | | | | | | | | | | | | | | | | | | Allows for one socket to be multiplexed for multiple requests. Doesn't use command sequence numbers for broadcasts - would make no sense.

* Fix SocketListener socket leak issue.Xianzhu Wang2011-09-291-2/+3
| | | | | | | | | | | | The problem was: if a socket is shared between SocketListener and another thread, only if the last reference is removed by SocketListener can the socket be closed, otherwise the socket will leak. This sometimes happens in netd's dnsproxyd. This change let the SocketClient own the socket and close the socket when the SocketClient is destructed.

* Workaround Motorola ril.so incompatiblity with Netlink changesMike J. Chen2011-06-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | To workaround a binary incompatiblity with Motorola's ril.so, I had to temporarily provide the old constructor for NetlinkListener as well as a new contructor that takes an additional format argument. There's still a slight chance of a problem because the size of the NetlinkListener has changed with the addition of the mFormat member, but so far I've not seen any obvious problem with that incompatiblity. Another way we could have worked around the incompatiblity is to have netd (the main user of the new format argument to NetlinkListener) keep track of the format itself in it's NetlinkHandler (derived from NetlinkListener) and supply it's own version of onDataAvailable() that's almost 100% identical to NetlinkListener's except for the decode() call. That would allow us not to modify NetlinkListener at all. Worth considering but I think it's more properly divided right now and we just have to make Motorola fix their code (and ideally not use our private APIs). This change should be reverted when Motorola's has fixed their ril to either not use our private APIs or to use our updated ones.

Also, reintroduce the const usage that was not in the original changes by Stan. Also fix some indent spacing. Change-Id: Ice9ec7f0d5c4a0673037e2e04a764d88a98f68eb Signed-off-by: Mike J.

Conflicts: libsysutils/src/NetlinkEvent.cpp Bring back the changes from Stan Chesnutt regarding adding NETLINK_ROUTE processing. The original commit message description was: Add NETLINK_ROUTE processing to the netlink client code, so that Ethernet physical-layer up/down events can be tracked. Upper layers will use these events to enable/disable Ethernet connectivity. The original change was reverted due to an incompatiblity with Motorola's ril.so binary. I'll submit a patch to workaround that incompatiblity separately. Change-Id: I4e97ac98833b10543e654c63ecae3b9b8c7db44f Signed-off-by: Mike J. Chen <mjchen@google.com>
