2008-06-09af_iucv: exploit target message class support of IUCVUrsula Braun1-0/+1
The first 4 bytes of data to be sent are stored additionally into the message class field of the send request. A receiving target program (not an af_iucv socket program) can make use of this information to pre-screen incoming messages. Signed-off-by: Ursula Braun <braunu@de.ibm.com> Signed-off-by: David S.

2008-06-09iucv: prevent cpu hotplug when walking cpu_online_map.Heiko Carstens1-4/+7
The code used preempt_disable() to prevent cpu hotplug, however that doesn't protect for cpus being added. So use get_online_cpus() instead.

2008-06-09iucv: fix section mismatch warning.Heiko Carstens1-1/+1
WARNING: net/iucv/built-in.o(.exit.text+0x9c): Section mismatch in reference from the function iucv_exit() to the variable .cpuinit.data:iucv_cpu_notifier This warning is caused by a reference from unregister_hotcpu_notifier() from an exit function to a cpuinitdata annotated data structurre. This is a false positive warning since for the non CPU_HOTPLUG case unregister_hotcpu_notifier() is a nop. Use __refdata instead of __cpuinitdata to get rid of the warning.

2008-06-04tipc: Message rejection rework preparatory changesAllan Stephens3-4/+31
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 <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-04tipc: Fix bugs in rejection of message with short headerAllan Stephens1-4/+6
This patch ensures that TIPC doesn't try to access non-existent message header fields when rejecting a message with a short header. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-04tipc: Message header creation optimizationsAllan Stephens1-6/+1

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: Add missing spinlock in name table display codeAllan Stephens1-1/+3
This patch ensures that the display code that traverses the publication lists belonging to a name table entry take its associated spinlock, to protect against a possible change to one of its "head of list" pointers caused by a simultaneous name table lookup operation by another thread of control.

2008-06-04tipc: Prevent display of name table types with no publicationsAllan Stephens1-0/+3
This patch adds a check to prevent TIPC's name table display code from listing a name type entry if it exists only to hold subscription info, rather than published names. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-04tipc: Optimize message initialization routineAllan Stephens7-18/+16
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.

2008-06-04tipc: Prevent access of non-existent field in short message headerAllan Stephens1-1/+3
This patch eliminates a case where TIPC's link code could try reading a field that is not present in a short message header. (The random value obtained was not being used, but the read operation could result in an invalid memory access exception in extremely rare circumstances.)

2008-06-04tipc: Minor optimizations to received message processingAllan Stephens3-25/+8
This patch enhances TIPC's handler for incoming messages in two ways: - the trivial, single-use routine for processing non-sequenced messages has been merged into the main handler - the interface that received a message is now identified without having to access and/or modify the associated sk_buff Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-04tipc: Fix minor bugs in link session number handlingAllan Stephens1-5/+12
This patch introduces a new, out-of-range value to indicate that a link endpoint does not have an existing session established with its peer, eliminating the risk that the previously used "invalid session number" value (i.e. zero) might eventually be assigned as a valid session number and cause incorrect link behavior. The patch also introduces explicit bit masking when assigning a new link session number to ensure it does not exceed 16 bits.

2008-06-04tipc: Fix bugs in message error code display when debuggingAllan Stephens1-3/+0
This patch corrects two problems in the display of error code information in TIPC messages when debugging: - no longer tries to display error code in NAME_DISTRIBUTOR messages, which don't have the error field - now displays error code in 24 byte data messages, which do have the error field Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-04tipc: Standardize error checking on incoming messages via native APIAllan Stephens1-16/+9

2008-06-04tipc: Fix bug in connection setup via native APIAllan Stephens1-6/+3
This patch fixes a bug that prevented TIPC from receiving a connection setup request message on a native TIPC port. The revised connection setup logic ensures that validation of the source of a connection-based message is skipped if the port is not yet connected to a peer.

2008-05-29tcp: Reorganize tcp_sock to fill 64-bit holes & improve localityIlpo Järvinen1-25/+25
I tried to group recovery related fields nearby (non-CA_Open related variables, to be more accurate) so that one to three cachelines would not be necessary in CA_Open. These are now contiguously deployed: struct sk_buff_head out_of_order_queue; /* 1968 80 */ /* --- cacheline 32 boundary (2048 bytes) --- */ struct tcp_sack_block duplicate_sack[1]; /* 2048 8 */ struct tcp_sack_block selective_acks[4]; /* 2056 32 */ struct tcp_sack_block recv_sack_cache[4]; /* 2088 32 */ /* --- cacheline 33 boundary (2112 bytes) was 8 bytes ago --- */ struct sk_buff * highest_sack; /* 2120 8 */ int lost_cnt_hint; /* 2128 4 */ int retransmit_cnt_hint; /* 2132 4 */ u32 lost_retrans_low; /* 2136 4 */ u8 reordering; /* 2140 1 */ u8 keepalive_probes; /* 2141 1 */ /* XXX 2 bytes hole, try to pack */ u32 prior_ssthresh; /* 2144 4 */ u32 high_seq; /* 2148 4 */ u32 retrans_stamp; /* 2152 4 */ u32 undo_marker; /* 2156 4 */ int undo_retrans; /* 2160 4 */ u32 total_retrans; /* 2164 4 */ ...and they're then followed by URG slowpath & keepalive related variables. Head of the out_of_order_queue always needed for empty checks, if that's empty (and TCP is in CA_Open), following ~200 bytes (in 64-bit) shouldn't be necessary for anything. If only OFO queue exists but TCP is in CA_Open, selective_acks (and possibly duplicate_sack) are necessary besides the out_of_order_queue but the rest of the block again shouldn't be (ie., the other direction had losses). As the cacheline boundaries depend on many factors in the preceeding stuff, trying to align considering them doesn't make too much sense. Commented one ordering hazard. There are number of low utilized u8/16s that could be combined get 2 bytes less in total so that the hole could be made to vanish (includes at least ecn_flags, urg_data, urg_mode, frto_counter, nonagle).
