      xfrm: Initialize the struct xfrm_dst behind the dst_enty field · 141e369d
      由 Steffen Klassert 提交于 
      We start initializing the struct xfrm_dst at the first field
behind the struct dst_enty. This is error prone because it
might leave a new field uninitialized. So start initializing
the struct xfrm_dst right behind the dst_entry.

      Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next · 921a678c
      由 David S. Miller 提交于 
      John Linville says:

====================
Several drivers see updates: mwifiex, ath9k, iwlwifi, brcmsmac,
wlcore/wl12xx/wl18xx, and a handful of others.  The bcma bus got a
lot of attention from Hauke Mehrtens.  The cfg80211 component gets
a flurry of patches for multi-channel support, and the mac80211
component gets the first few VHT (11ac) and 60GHz (11ad) patches.
This also includes the removal of the iwmc3200 drivers, since the
hardware never became available to normal people.

Additionally, the NFC subsystem gets a series of updates.  According to
Samuel, "Here are the interesting bits:

- A better error management for the HCI stack.
- An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are
  now reserved only when there's a client for it.
- Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and
  write NFC tags and also establish a p2p link with this dongle now.
- A few LLCP fixes."

Finally, this includes another pull of the fixes from the wireless
tree in order to resolve some merge issues.

      tipc: remove print_buf and deprecated log buffer code · 869dd466
      由 Erik Hugne 提交于 
      The internal log buffer handling functions can now safely be
removed since there is no code using it anymore.  Requests to
interact with the internal tipc log buffer over netlink (in
config.c) will report 'obsolete command'.

This represents the final removal of any references to a
struct print_buf, and the removal of the struct itself.
We also get rid of a TIPC specific Kconfig in the process.

Finally, log.h is removed since it is not needed anymore.

      tipc: phase out most of the struct print_buf usage · dc1aed37
      由 Erik Hugne 提交于 
      The tipc_printf is renamed to tipc_snprintf, as the new name
describes more what the function actually does.  It is also
changed to take a buffer and length parameter and return
number of characters written to the buffer.  All callers of
this function that used to pass a print_buf are updated.

Final removal of the struct print_buf itself will be done
synchronously with the pending removal of the deprecated
logging code that also was using it.

Functions that build up a response message with a list of
ports, nametable contents etc. are changed to return the number
of characters written to the output buffer. This information
was previously hidden in a field of the print_buf struct, and
the number of chars written was fetched with a call to
tipc_printbuf_validate.  This function is removed since it
is no longer referenced nor needed.

A generic max size ULTRA_STRING_MAX_LEN is defined, named
in keeping with the existing TIPC_TLV_ULTRA_STRING, and the
various definitions in port, link and nametable code that
largely duplicated this information are removed.  This means
that amount of link statistics that can be returned is now
increased from 2k to 32k.

The buffer overflow check is now done just before the reply
message is passed over netlink or TIPC to a remote node and
the message indicating a truncated buffer is changed to a less
dramatic one (less CAPS), placed at the end of the message.

      tipc: simplify print buffer handling in tipc_printf · e2dbd601
      由 Erik Hugne 提交于 
      tipc_printf was previously used both to construct debug traces
and to append data to buffers that should be sent over netlink
to the tipc-config application.  A global print_buffer was
used to format the string before it was copied to the actual
output buffer.  This could lead to concurrent access of the
global print_buffer, which then had to be lock protected.
This is simplified by changing tipc_printf to append data
directly to the output buffer using vscnprintf.

With the new implementation of tipc_printf, there is no longer
any risk of concurrent access to the internal log buffer, so
the lock (and the comments describing it) are no longer
strictly necessary.  However, there are still a few functions
that do grab this lock before resizing/dumping the log
buffer.  We leave the lock, and these functions untouched since
they will be removed with a subsequent commit that drops the
deprecated log buffer handling code

      tipc: simplify link_print by divorcing it from using tipc_printf · 5deedde9
      由 Paul Gortmaker 提交于 
      To pave the way for a pending cleanup of tipc_printf, and
removal of struct print_buf entirely, we make that task simpler
by converting link_print to issue its messages with standard
printk infrastructure.  [Original idea separated from a larger
patch from Erik Hugne <erik.hugne@ericsson.com>]

      tipc: remove TIPC packet debugging functions and macros · 568fc588
      由 Erik Hugne 提交于 
      The link queue traces and packet level debug functions served
a purpose during early development, but are now redundant
since there are other, more capable tools available for
debugging at the packet level.

The TIPC_DEBUG Kconfig option is removed since it does not
provide any extra debugging features anymore.

This gets rid of a lot of tipc_printf usages, which will
make the pending cleanup work of that function easier.

      tipc: use standard printk shortcut macros (pr_err etc.) · 2cf8aa19
      由 Erik Hugne 提交于 
      All messages should go directly to the kernel log.  The TIPC
specific error, warning, info and debug trace macro's are
removed and all references replaced with pr_err, pr_warn,
pr_info and pr_debug.

Commonly used sub-strings are explicitly declared as a const
char to reduce .text size.

Note that this means the debug messages (changed to pr_debug),
are now enabled through dynamic debugging, instead of a TIPC
specific Kconfig option (TIPC_DEBUG).  The latter will be
phased out completely
