2008-05-19tipc: Cosmetic cleanup of topology service codeAllan Stephens1-5/+3
This patch contains a set of cosmetic changes to TIPC's network topology service subsystem, including: - updates to comments (including copyright dates) - re-ordering structure fields to group them more logically - removal of optional debugging code that is no longer required - minor changes to whitespace to conform to Linux coding conventions Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-05-19tipc: Consolidate subscriber & subscriber port referencesAllan Stephens1-86/+113
This patch modifies TIPC's network topology service so that it only requires a single reference table entry per subscriber connection, rather than two. This is achieved by letting the reference to the server port communicating with the subscriber act as the reference to the subscriber object itself. (Since the subscriber cannot exist without its port, and vice versa, this dual role for the reference is perfectly natural.) This consolidation reduces the size of the reference table by 50% in the default configuration. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-05-19tipc: Fix bug in topology server byte swapping routineAllan Stephens1-3/+1
This patch fixes TIPC's topology server so that it does byte swapping correctly when endianness conversion is required. (Note: This bug only impacted an application if it issues a subscription request to a topology server on another node, rather than the server on it's own node; since the topology server is normally not accessible by off-node applications, most TIPC applications were not impacted by the bug.)

2008-05-19tipc: Add support for customized subscription endiannessAllan Stephens1-19/+16
This patch enables TIPC's topology server code to do customized endianness conversions on a per-subscription basis. (This capability is needed to support the upcoming consolidation of subscriber and subscription object references.)

2008-05-19tipc: Add support for customized subscription overlap handlingAllan Stephens1-1/+3
This patch enables TIPC's topology server code to do customized overlap detection handling on a per-subscription basis.

2008-05-12tipc: Fix race condition when creating socket or native portAllan Stephens1-0/+1
This patch eliminates the (very remote) chance of a crash resulting from a partially initialized socket or native port unexpectedly receiving a message. Now, during the creation of a socket or native port, the underlying generic port's lock is not released until all initialization required to handle incoming messages has been done.

2006-10-18[TIPC]: Added subscription cancellation capabilityLijun Chen1-15/+84
This patch allows a TIPC application to cancel an existing topology service subscription by re-requesting the subscription with the TIPC_SUB_CANCEL filter bit set. (All other bits of the cancel request must match the original subscription request.)

2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar1-1/+1
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-20[TIPC]: Remove inlines from *.cSam Ravnborg1-1/+1
With reference to latest discussions on linux-kernel with respect to inline here is a patch for tipc to remove all inlines as used in the .c files. See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch.

2006-03-20[TIPC]: Fix simple sparse warningsSam Ravnborg1-14/+14
Tried to run the new tipc stack through sparse. Following patch fixes all cases where 0 was used as replacement of NULL. Use NULL to document this is a pointer and to silence sparse. This brough sparse warning count down with 127 to 24 warnings. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Per Liden <per.liden@ericsson.com> Signed-off-by: David S.
