A phonet packet is limited to USHRT_MAX bytes, this is never checked during tx which means that the user can specify any size he wishes, and the kernel will attempt to allocate that size. In the good case, it'll lead to the following warning, but it may also cause the kernel to kick in the OOM and kill a random task on the server.

commit 2f533844 (tcp: allow splice() to build full TSO packets) added a regression for splice() calls using SPLICE_F_MORE. We need to call tcp_flush() at the end of the last page processed in tcp_sendpages(), or else transmits can be deferred and future sends stall. Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but with different semantic. For all sendpage() providers, its a transparent change.

The driver uses a 2-order allocation, which is too much on architectures like ppc64, which has a 64KiB page. This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

This patch fixes a link problem on BCM57712 + BCM8727 designs in which the TX laser is controller by GPIO, after 1.60.xx drivers were previously loaded. On these designs the TX_LASER is enabled by logic AND between the PHY (through MDIO), and the GPIO. When an old driver is used, it disables the MDIO part, hence the GPIO control had no affect de facto.

Modified from original patch from Chris. The sky2 driver has to have 8 byte alignment of receive buffer on some chip versions. On architectures which don't support efficient unaligned access this doesn't work very well. The solution is to just copy all received packets which is what the driver already does for small packets. This allows the driver to be used on the Tilera TILEmpower-Gx, since the tile architecture doesn't currently handle kernel unaligned accesses, just userspace.

由 Shlomo Pongratz 提交于
The current implemenation was buggy for slaves who use ndo_neigh_setup, since the networking stack invokes the bonding device ndo entry (from neigh_params_alloc) before any devices are enslaved, and the bonding driver can't further delegate the call at that point in time. As a result when bonding IPoIB devices, the neigh_cleanup hasn't been called. Fix that by deferring the actual call into the slave ndo_neigh_setup from the time the bonding neigh_setup is called.

由 Thomas Graf 提交于
getsockopt(..., SCTP_EVENTS, ...) performs a length check and returns an error if the user provides less bytes than the size of struct sctp_event_subscribe. Struct sctp_event_subscribe needs to be extended by an u8 for every new event or notification type that is added. This obviously makes getsockopt fail for binaries that are compiled against an older versions of <net/sctp/user.h> which do not contain all event types. This patch changes getsockopt behaviour to no longer return an error if not enough bytes are being provided by the user. Instead, it returns as much of sctp_event_subscribe as fits into the provided buffer. This leads to the new behavior that users see what they have been aware of at compile time. The setsockopt(..., SCTP_EVENTS, ...) API is already behaving like this. Signed-off-by: NThomas Graf <tgraf@suug.ch> Acked-by: NVlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: NDavid S.
