      net: Fix memory leak in the proto_register function · 7e56b5d6
      Catalin Marinas authored
      If the slub allocator is used, kmem_cache_create() may merge two or more
      kmem_cache's into one but the cache name pointer is not updated and
      kmem_cache_name() is no longer guaranteed to return the pointer passed
      to the former function. This patch stores the kmalloc'ed pointers in the
      corresponding request_sock_ops and timewait_sock_ops structures.

      tcp: Do not use TSO/GSO when there is urgent data · 33cf71ce
      Petr Tesarik authored
      This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=12014
      
      Since most (if not all) implementations of TSO and even the in-kernel
      software GSO do not update the urgent pointer when splitting a large
      segment, it is necessary to turn off TSO/GSO for all outgoing traffic
      with the URG pointer set.
      
      Looking at tcp_current_mss (and the preceding comment) I even think
      this was the original intention. However, this approach is insufficient,
      because TSO/GSO is turned off only for newly created frames, not for
      frames which were already pending at the arrival of a message with
      MSG_OOB set. These frames were created when TSO/GSO was enabled,
      so they may be large, and they will have the urgent pointer set
      in tcp_transmit_skb().
      
      With this patch, such large packets will be fragmented again before
      going to the transmit routine.
      
      As a side note, at least the following NICs are known to screw up
      the urgent pointer in the TCP header when doing TSO:
      
      	Intel 82566MM (PCI ID 8086:1049)
      	Intel 82566DC (PCI ID 8086:104b)
      	Intel 82541GI (PCI ID 8086:1076)
      	Broadcom NetXtreme II BCM5708 (PCI ID 14e4:164c)

      axnet_cs / pcnet_cs: moving PCMCIA_DEVICE_PROD_ID for Netgear FA411 · 208fbec5
      Cord Walter authored
      Hi,
      
      after noticing that my Netgear FA411 (PCMCIA-NIC) [1] stopped working with
      the release of the 2.6.25 kernel (sidux-version), I checked the
      respective driver sources and noticed that the pcnet_cs driver bailed
      out with "use axnet_cs instead" for the Netgear FA411, but axnet_cs
      doesn't claim this ID.
      
      I compiled a kernel with the PCMCIA-ID for the netgear card moved to
      axnet_cs from pcnet_cs which worked. I then contacted sidux-kernel
      maintainer Stefan Lippers-Hollmann who turned the info into this patch
      and integrated it into the kernel:
      
      <http://svn.berlios.de/svnroot/repos/fullstory/linux-sidux-2.6/trunk/debian/patches/features/2.6.27.4_PCMCIA_move-PCMCIA-ID-for-Netgear-FA411-from-pcnet_cs-to-axnet_cs.patch>
      
      This works for me and AFAIK there were no reports of any breakage for
      other devices on sidux-support.
      
      This looks like a trivial patch, but since I have very limited
      experience with kernel modifications  I might be woefully wrong there.
      But if there are no side effects of this patch, is it possible to get it
      into the official kernel?
      
      I can provide more detailed information on the affected hardware if
      necessary.
