Bo Huang 4df4dfedf6 When new error happend,then errno should be updated accordingly.
Otherwise, need to keep previous errno.

Reproduced steps:
pre-condition:
DUT support external SDcard or Usb mass storage;

1. Insert blank(no partition) SDcard or UMS to DUT;

Expected result:
Should prompt user with storage error.

Test result:
There is no notification for error.

Error log:
01-01 01:06:49.239 I/fsck_msdos( 200): fsck_msdos terminated by exit(8)
01-01 01:06:49.239 E/Vold ( 200): /dev/block/vold/179:16 failed FS checks (I/O error)
01-01 01:06:49.239 D/Vold ( 200): Volume sdcard1 state changing 3 (Checking) -> 1 (Idle-Unmounted)
01-01 01:06:49.239 W/Vold ( 200): Returning OperationFailed - no handler for errno 0)

Root cause analysis:
1.Volume::setState will call senBroadcase to send out state notification;
2.Finally, SocketClient::sendDataLockedv was called to sent message.
In sendDataLockedv funtion,  when current == iovcnt,  e is 0 by default.
So Vold get incorrect errno.

Lorenzo Colitti d7ff7ea652 Support parsing netlink route messages.

Lorenzo Colitti 9b34293566 Improvements to netlink event parsing.
1. Accept that parseNetlinkMessage can only parse one netlink
   message, because its way of returning output is to modify its
   member variables (mAction, mParams, etc.). Currently, it
   loops through all the messages it finds, updating its member
   variables as it goes along, and always returns true at the end
   of the buffer. This has the following problems:

   1. Since the function always returns true even when no
      messages were parsed, the caller has no way to know if
      parsing succeeded, and we get lots of "No subsystem found
      in netlink event" logs if the buffer did not contain any
      valid messages we were interested in.
   2. If there are multiple messages in the buffer, all but the
      last message will be silently ignored.
   3. If there are multiple messages and previous messages have
      more parameters than the last one, the resulting event will
      have a mixture of parameters from multiple messages.

   Instead of doing all this, change the contract to "parse the
   first valid message of interest in the buffer and return true,
   or return false if there were no such messages", and update
   the code and the comments accordingly.

2. Modify the caller (NetlinkListener) so it doesn't log an
   error when parseBinaryNetlinkMessage returns false, because
   this can now simply mean that we weren't interested in that
   particular message. parseBinaryNetlinkMessage already logs
   more informative errors.

3. Provide utility functions to check received message lengths and
   to convert message types to message names.

4. Simplify logging duplicate attributes.

5. Use the appropriate IFLA_xxx macros instead of rolling our own
   code to parse link state messages.

6. Move all the parsing code out to per-message-type parsing
   functions to order to simplify parseBinaryNetlinkMessage.

* 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

Lorenzo Colitti c7eec83f08 Support parsing RDNSS ND options from netlink.
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.

Lorenzo Colitti 526b838c9d Switch back to subsystem "net" for netlink events.
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".

action codes instead of a new subsystem.

Xianzhu Wang 4520246d35 Fix SocketListener socket leak issue.
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.
