2008-06-04tipc: Message rejection rework preparatory changesAllan Stephens1-2/+29
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. Signed-off-by: Allan Stephens <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-06-04tipc: Expand link sequence gap field to 13 bitsAllan Stephens1-4/+4
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.

2008-06-04tipc: Optimize message initialization routineAllan Stephens1-2/+1
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.

2008-03-06[TIPC]: Enhancements to message header writingAllan Stephens1-2/+4
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.

2008-03-06[TIPC]: Use correct bitmask when setting versionAllan Stephens1-1/+1
This patch ensures that the 3-bit version field of the TIPC message header is masked correctly when written into a message. Signed-off-by: Allan Stephens <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-03-06[TIPC]: Minor cleanup of message header codeAllan Stephens1-11/+8
This patch eliminates some unused or duplicate message header symbols, and fixes up the comments and/or location of a few other symbols. Signed-off-by: Allan Stephens <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-03-06[TIPC]: Removal of message header option codeAllan Stephens1-23/+0
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.

2008-02-07[TIPC]: Kill unused static inline (x5)Ilpo Järvinen1-5/+0
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) Signed-off-by: Ilpo Järvinen <[email protected]> Signed-off-by: David S.

2007-04-25[TIPC]: Enhancements to msg_set_bits() routineAllan Stephens1-4/+7
This patch makes two enhancements to msg_set_bits(): 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.

2007-04-25[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo1-3/+4
To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
