      ISDN: pcbit: off by one bugs in pcbit_set_msn() · 7bcc6738
      由 Dan Carpenter 提交于 
      1) We don't allocate enough space for the NUL terminator so we end up
   corrupting one character beyond the end of the buffer.

2) The "len - 1" should just be "len".  The code is trying to copy a
   word from a buffer up to a comma or the last word in the buffer.
   Say you have the buffer, "foo,bar,baz", then this code truncates the
   last letter off each word so you get "fo", "ba", and "ba".  You would
   hope this kind of bug would get noticed in testing...

   I'm not very familiar with this code and I can't test it, but I think
   we should copy the final character.

      net: fix the counter ICMP_MIB_INERRORS/ICMP6_MIB_INERRORS · 7304fe46
      由 Duan Jiong 提交于 
      When dealing with ICMPv[46] Error Message, function icmp_socket_deliver()
and icmpv6_notify() do some valid checks on packet's length, but then some
protocols check packet's length redaudantly. So remove those duplicated
statements, and increase counter ICMP_MIB_INERRORS/ICMP6_MIB_INERRORS in
function icmp_socket_deliver() and icmpv6_notify() respectively.

In addition, add missed counter in udp6/udplite6 when socket is NULL.

      sctp: Fixup v4mapped behaviour to comply with Sock API · 299ee123
      由 Jason Gunthorpe 提交于 
      The SCTP socket extensions API document describes the v4mapping option as
follows:

8.1.15.  Set/Clear IPv4 Mapped Addresses (SCTP_I_WANT_MAPPED_V4_ADDR)

   This socket option is a Boolean flag which turns on or off the
   mapping of IPv4 addresses.  If this option is turned on, then IPv4
   addresses will be mapped to V6 representation.  If this option is
   turned off, then no mapping will be done of V4 addresses and a user
   will receive both PF_INET6 and PF_INET type addresses on the socket.
   See [RFC3542] for more details on mapped V6 addresses.

This description isn't really in line with what the code does though.

Introduce addr_to_user (renamed addr_v4map), which should be called
before any sockaddr is passed back to user space. The new function
places the sockaddr into the correct format depending on the
SCTP_I_WANT_MAPPED_V4_ADDR option.

Audit all places that touched v4mapped and either sanely construct
a v4 or v6 address then call addr_to_user, or drop the
unnecessary v4mapped check entirely.

Audit all places that call addr_to_user and verify they are on a sycall
return path.

Add a custom getname that formats the address properly.

Several bugs are addressed:
 - SCTP_I_WANT_MAPPED_V4_ADDR=0 often returned garbage for
   addresses to user space
 - The addr_len returned from recvmsg was not correct when
   returning AF_INET on a v6 socket
 - flowlabel and scope_id were not zerod when promoting
   a v4 to v6
 - Some syscalls like bind and connect behaved differently
   depending on v4mapped

Tested bind, getpeername, getsockname, connect, and recvmsg for proper
behaviour in v4mapped = 1 and 0 cases.

      net: kernel-doc compliant documentation for net_device · 536721b1
      由 Karoly Kemeny 提交于 
      Net_device is a vast and important structure, but it has no kernel-doc
compliant documentation. This patch extracts the comments from the structure
to clean it up, and let the scripts extract documentation from it. I know that
the patch is big, but it's just reordering of comments into the appropriate
form, and adding a few more, for the missing members.

      Vince Bridgers says:

====================
net: stmmac: Improve mcast/ucast filter for snps

This patch series adds Synopsys specific bindings for the Synopsys EMAC
filter characteristics since those are implementation dependent. The
multicast and unicast filtering code was improved to handle different
configuration variations based on device tree settings.

I verified the operation of the multicast and unicast filters through
Synopsys support as requested during the V1 review, and tested the GMAC
configuration on an Altera Cyclone 5 SOC (which supports 256 multicast
bins and 128 Unicast addresses). The 10/100 variant of this driver
modification was not tested, although it was compile tested. I shared
the email thread results of the investigation through Synopsys with the
stmmac maintainer.

V4: Remove patch from series that addressed a sparse issue from a
    down rev'd version of sparse that does not show up in the
    latest version of sparse.
V3: Break up the patch into interface and functional change patches
    per review comments
V2: Confirm with Synopsys methods to determine number of Multicast bins
    and Unicast address filter entries per first round review comments.

      net: stmmac: Support devicetree configs for mcast and ucast filter entries · 3b57de95
      由 Vince Bridgers 提交于 
      This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case #8000684337 and shared with the maintainer.

      dts: Add bindings for multicast hash bins and perfect filter entries · 94ceaa26
      由 Vince Bridgers 提交于 
      This change adds bindings for the number of multicast hash bins and perfect
filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is
configurable at device creation time, and can be configured for a different
number of multicast hash bins and a different number of perfect filter
entries. The device does not provide a way to query these parameters,
therefore parameters are required. The Altera Cyclone V SOC has support for
256 multicast hash bins and 128 perfect filter entries, and is different
than what's currently provided in the stmmac driver.
