tipc: Message rejection rework preparatory changes

2008-06-05T00:54:48+00:00

This patch defines a few new message header manipulation routines,
and generalizes the usefulness of another, in preparation for upcoming
rework of TIPC's message rejection code.

tipc: Expand link sequence gap field to 13 bits

2008-06-05T00:47:30+00:00

This patch increases the "sequence gap" field of the LINK_PROTOCOL
message header from 8 bits to 13 bits (utilizing 5 previously
unused 0 bits).  This ensures that the field is big enough to
indicate the loss of up to 8191 consecutive messages on the link,
thereby accommodating the current worst-case scenario of 4000
lost messages.

tipc: Optimize message initialization routine

2008-06-05T00:37:34+00:00

This patch eliminates the rarely-used "error code" argument
when initializing a TIPC message header, since the default
value of zero is the desired result in most cases; the few
exceptional cases now set the error code explicitly.

[TIPC]: Enhancements to message header writing

2008-03-06T23:08:10+00:00

This patch makes two enhancements to the routine used to
set bit fields within a TIPC message header:

 1) It now ignores any bits of the new field value that are not
    covered by the mask being used.  (Previously, if the new value
    exceeded the size of the mask the extra bits could corrupt
    other fields in the message header word being updated.)

 2) The code has been optimized to minimize the number of run-time
    endianness conversion operations by leveraging the fact that the
    mask (and, in some cases, the value as well) is constant and the
    necessary conversion can be performed by the compiler.

[TIPC]: Use correct bitmask when setting version

2008-03-06T23:07:42+00:00

This patch ensures that the 3-bit version field of the TIPC
message header is masked correctly when written into a message.

[TIPC]: Minor cleanup of message header code

2008-03-06T23:06:55+00:00

This patch eliminates some unused or duplicate message header
symbols, and fixes up the comments and/or location of a few
other symbols.

[TIPC]: Removal of message header option code

2008-03-06T23:05:07+00:00

This patch removes code associated with optional, user-specified
fields of the TIPC message header.  Such fields were never
utilized by TIPC, and have now been removed from the protocol
specification.

[TIPC]: Kill unused static inline (x5)

2008-02-08T02:17:13+00:00

All these static inlines are unused:

in_own_zone     1 (net/tipc/addr.h)
msg_dataoctet   1 (net/tipc/msg.h)
msg_direct      1 (include/net/tipc/tipc_msg.h)
msg_options     1 (include/net/tipc/tipc_msg.h)
tipc_nmap_get   1 (net/tipc/bcast.h)
