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.

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.

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:

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. Signed-off-by:

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.) Signed-off-by:

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:

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. Signed-off-by:

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:

This patch re-orders & re-groups the error checks performed on messages being delivered to native API ports, in order to clarify the similarities and differences required for the various message types. Signed-off-by:

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. Signed-off-by:

Turn on special bits to save more power when device is shutdown. Tested on a limited range of hardware, some of the bits are for hardware that probably isn't even in production (like Yukon Supreme) and was ported from the vendor driver. Signed-off-by:

Match the suspend/resume code ordering in e100/e1000e more closely. For example the configuration space should be saved on suspend even for devices that are not up. Signed-off-by:

The memory mapped device configuration space is lost during hibernate. Save and restore it (fixes 'swapped mac' problem). Signed-off-by:

Tobias Diedrich authored
When hibernating in 'shutdown' mode, after saving the image the suspend hook is not called again. However, if the device is in promiscous mode, wake-on-lan will not work. This adds a shutdown hook to setup wake-on-lan before the final shutdown. Signed-off-by:

cxgb3 uses lro_* functions and selects INET_LRO, but this doesn't help unless INET is already enabled, so make the driver depend on INET also. sge.c:(.text+0x9f09a): undefined reference to `lro_flush_all' sge.c:(.text+0x9f62f): undefined reference to `lro_receive_skb' sge.c:(.text+0x9f8a3): undefined reference to `lro_receive_frags' sge.c:(.text+0x9fbe0): undefined reference to `lro_vlan_hwaccel_receive_skb' sge.c:(.text+0x9ffcd): undefined reference to `lro_vlan_hwaccel_receive_frags' Signed-off-by:

Add multi-slice/MSI-X support. By default, a single slice (and the normal firmware) are used. To enable msi-x, multi-slice mode, one must load the driver with myri10ge_max_slices set to either -1, or something larger than 1. Signed-off-by:

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).
