When support for binding to 'mapped INADDR_ANY (::ffff.0.0.0.0)' was added
in 0f8d3c7a the rest of the code
wasn't told so now it's possible to bind IPv6 datagram socket to
::ffff.0.0.0.0, connect it to another IPv4 address and it will all
work except for getsockhame() which does not return the local address
as expected.

To give getsockname() something to work with check for 'mapped INADDR_ANY'
when connecting and update the in-core source addresses appropriately.

The sendmmsg() introduced by commit 228e548e "net: Add sendmmsg socket system
call" is capable of sending to multiple different destination addresses.

SMACK is using destination's address for checking sendmsg() permission.
However, security_socket_sendmsg() is called for only once even if multiple
different destination addresses are passed to sendmmsg().

Therefore, we need to call security_socket_sendmsg() for each destination
address rather than only the first destination address.

Since calling security_socket_sendmsg() every time when only single destination
address was passed to sendmmsg() is a waste of time, omit calling
security_socket_sendmsg() unless destination address of previous datagram and
that of current datagram differs.

To limit the amount of time we can spend in sendmmsg, cap the
number of elements to UIO_MAXIOV (currently 1024).

For error handling an application using sendmmsg needs to retry at
the first unsent message, so capping is simpler and requires less
application logic than returning EINVAL.

sendmmsg uses a similar error return strategy as recvmmsg but it
turns out to be a confusing way to communicate errors.

The current code stores the error code away and returns it on the next
sendmmsg call. This means a call with completely valid arguments could
get an error from a previous call.

Change things so we only return an error if no datagrams could be sent.
If less than the requested number of messages were sent, the application
must retry starting at the first failed one and if the problem is
persistent the error will be returned.

This matches the behaviour of other syscalls like read/write - it
is not an error if less than the requested number of elements are sent.

This isn't really critical any more, since other patches (commit

While `pci_eisa_driver' still refer `pci_eisa_init', the .probe() function
should not be called after init memory release, as pointed out by commit
74b9a297. The structure is still referenced in the drivers subsystem, and can
be accesseed through sysfs, so the modpost warning is a false positive. Mark
it as such.

In the same time, the warning referenced in 005bdad7 did only mention
`pci_eisa_driver', not `pci_eisa_pci_tbl', so remove its marking.

drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC Lines (here: Asus M2A-VM HDMI)

    Some integrated ATI Radeon chipset implementations with add-on HDMI card
    (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even
    when the add-on card is not plugged in or HDMI is disabled in BIOS setup.
    In this case, drm_get_edid() and drm_edid_block_valid() periodically
    dump data and kernel errors into system log files and onto terminals.
    For these connectors DDC probing is extended by a check for a correct
    EDID header. Only in case a valid EDID header is also found, the
    (HDMI or DVI) connector will be used by the Radeon driver. This prevents
    the kernel driver from useless flooding of logs and terminal sessions with
    EDID dumps and error messages.
    This patch adds a flag 'requires_extended_probe' to the radeon_connector
    structure. In function radeon_connector_needs_extended_probe() this flag
    can be set on a chipset family/vendor/connector type specific basis.
    In addition, function radeon_ddc_probe() has been adapted to perform
    extended DDC probing if required by the connector's flag.
    Requires function drm_edid_header_is_valid() in DRM module provided by
    [PATCH] drm: Separate EDID Header Check from EDID Block Check.

    Tested for kernel 2.6.35, 2.6.38 and 3.0 on Asus M2A-VM HDMI board

    and replaces EDID header check part of function drm_edid_block_valid()
    by a call of drm_edid_header_is_valid().
    This is a prerequisite to extend DDC probing, e. g. in function
    radeon_ddc_probe() for Radeon devices, by a central EDID header check.
