uapi: export all headers under uapi directories

2017-05-10T15:21:54+00:00

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-blackfin/shmparam.h
asm-blackfin/ucontext.h
asm-c6x/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret  for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch//include/uapi/asm/Kbuild;
 - arch//include/asm/Kbuild.

Merge tag 'xtensa-20170507' of git://github.com/jcmvbkbc/linux-xtensa

2017-05-08T19:29:46+00:00

Pull Xtensa updates from Max Filippov:

 - clearly mark references to spilled register locations with SPILL_SLOT
   macros

 - clean up xtensa ptrace: use generic tracehooks, move internal kernel
   definitions from uapi/asm to asm, make locally-used functions static,
   fix code style and alignment

 - use command line parameters passed to ISS as kernel command line.

xtensa: move internal ptrace definitions from uapi/asm to asm

2017-05-01T14:00:10+00:00

Stack frame layout diagram, kernel stack size and exception_handlers
offsets are used by the kernel and are not supposed to be accessible to
userspace. Move these definitions from uapi/asm/ptrace.h to asm/ptrace.h

New getsockopt option to get socket cookie

2017-04-08T15:07:01+00:00

Introduce a new getsockopt operation to retrieve the socket cookie
for a specific socket based on the socket fd.  It returns a unique
non-decreasing cookie for each socket.

net: Introduce SO_INCOMING_NAPI_ID

2017-03-25T03:49:31+00:00

This socket option returns the NAPI ID associated with the queue on which
the last frame is received. This information can be used by the apps to
split the incoming flows among the threads based on the Rx queue on which
they are received.

If the NAPI ID actually represents a sender_cpu then the value is ignored
and 0 is returned.

sock: introduce SO_MEMINFO getsockopt

2017-03-22T18:18:58+00:00

Allows reading of SK_MEMINFO_VARS via socket option. This way an
application can get all meminfo related information in single socket
option call instead of multiple calls.

Adds helper function, sk_get_meminfo(), and uses that for both
getsockopt and sock_diag_put_meminfo().

tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPING

2016-11-30T15:04:25+00:00

This patch exports the sender chronograph stats via the socket
SO_TIMESTAMPING channel. Currently we can instrument how long a
particular application unit of data was queued in TCP by tracking
SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having
these sender chronograph stats exported simultaneously along with
these timestamps allow further breaking down the various sender
limitation.  For example, a video server can tell if a particular
chunk of video on a connection takes a long time to deliver because
TCP was experiencing small receive window. It is not possible to
tell before this patch without packet traces.

To prepare these stats, the user needs to set
SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags
while requesting other SOF_TIMESTAMPING TX timestamps. When the
timestamps are available in the error queue, the stats are returned
in a separate control message of type SCM_TIMESTAMPING_OPT_STATS,
in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME,
TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.
