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:

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:

This patch eliminates several cases where message header fields were being set to the same value twice. Signed-off-by:

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:

Allan Stephens authored
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:

Use netdev_alloc_skb for rx buffer allocation. This sets skb->dev and can be overriden for NUMA machines. This device is PowerPC only, so not tested or compiled. 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:

Rx allocation failure at runtime is non-fatal. For normal Rx frame, it just reuses the buffer, and during setup it just continues with a smaller receive buffer pool. Compile tested only. 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:
