2011-03-13T20:35:16+00:00

Adds support for the SO_RCVTIMEO socket option to TIPC's socket

Thanks go out to Raj Hegde  for his contribution
to the development and testing this enhancement.

tipc: Allow receiving into iovec containing multiple entries

2011-03-13T20:35:16+00:00

Enhances TIPC's socket receive routines to support iovec structures
containing more than a single entry. This change leverages existing
sk_buff routines to do most of the work; the only significant change
to TIPC itself is that an sk_buff now records how much data has been
already consumed as an numeric offset, rather than as a pointer to
the first unread data byte.

tipc: Prevent invalid memory access when sending to configuration service

2011-02-23T23:05:07+00:00

Reject TIPC configuration service messages without a full message
header.  Previously, an application that sent a message to the
configuration service that was too short could cause the validation
code to access an uninitialized field in the msghdr structure,
resulting in a memory access exception.

tipc: Remove unused global variable tipc_user_count

2011-02-23T23:05:06+00:00

Eliminates a global variable that was previously used by TIPC's user
registry to track the number of distinct applications using TIPC. Due to
the recent elimination of the user registry this variable no longer serves
any purpose and can be removed.

tipc: remove extraneous braces from single statements

2011-01-01T21:57:57+00:00

Cleans up TIPC's source code to eliminate the presence of unnecessary
use of {} around single statements.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

tipc: remove zeroing assignments to static global variables

2011-01-01T21:57:57+00:00

Cleans up TIPC's source code to eliminate the needless initialization
of static variables to zero.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

tipc: split variable assignments out of conditional expressions

2011-01-01T21:57:56+00:00

Cleans up TIPC's source code to eliminate assigning values to variables
within conditional expressions, improving code readability and reducing
warnings from various code checker tools.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

tipc: cleanup various cosmetic whitespace issues

2011-01-01T21:57:56+00:00

Cleans up TIPC's source code to eliminate deviations from generally
accepted coding conventions relating to leading/trailing white space
and white space around commas, braces, cases, and sizeof.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

tipc: recode getsockopt error handling for better readability

2011-01-01T21:57:55+00:00

The existing code for the copy to user and error handling at the
end of getsockopt isn't easy to follow, due to the excessive use
of if/else.  By simply using return where appropriate, it can be
made smaller and easier to follow at the same time.

useful purpose.
