This patch optimizes TIPC neighbor discovery code to avoid testing for a null node pointer when the pointer is already known to be non-null. Signed-off-by:

This patch ensures that the simultaneous discovery of the same neighboring node by multiple interfaces does not cause TIPC to add the node into its internal data structures more than once. Signed-off-by:

This patch prevents a TIPC configuration command requiring network administrator privileges from triggering an skbuff underrun if it is issued by a process lacking those privileges. The revised error handling code avoids the use of a potentially uninitialized global variable by transforming the unauthorized command into a new command, then following the standard command processing path to generate the required error message.

These devices use the private area of appropriate size for statistics. Turning them to use on-device ones make them "privless" and thus - really small wrt kmalloc cache, they are allocated from. Besides, code looks nicer, because of absence of multi-braced type casts and dereferences. [ Fix build failures -DaveM ] Signed-off-by:

The ipmr uses ipip tunnels for its purposes and updates the tunnels' stats, but the ipip driver is already switched to use on-device ones. Actually, this is a part of the patch #4 from this set. Signed-off-by:

Just switch from tunnel->stat to tunnel->dev->stats. The ip_tunnel->stat member itself will be removed after I fix its other users (very soon). Signed-off-by:

Even though bridges require 6 fields from struct net_device_stats, the on-device stats are always there, so we may just use them. The br_dev_get_stats is no longer required after this. Signed-off-by:

There are some sysctls left to be switched to read-only, but they are all in ipv6, so complete with them. Signed-off-by:

Parts of fragments-related sysctls are read-only, but this is done by cloning all the tables and dropping write-bits from mode. Do the same but with read-only root. Signed-off-by:
-
Pavel Emelyanov authored
The error code is ignored now, but ipv6 is a module and one can be loaded under memory pressure, so the error may occur (in theory). Besides, I'm going to handle error returned from registering a read-only part of the table, so ignoring this one, while handing the other one would look strange. (However, this possibility of error is rather small, so I'm not sure whether this is a candidate for current net tree). Signed-off-by:

The fragments sysctls also contains some, that are to be visible, but read-only in net namespaces. The naming in net/core/sysctl_net_core.c is - tables, that are to be registered in namespaces have a "ns" word in their names. So rename ones in ipv4/ip_fragment.c and ipv6/reassembly.c to fit this. Signed-off-by:

Most of the net/core/xxx sysctls are read-only now, but this goal is achieved with excessive memory consumption in each namespace - the whole table is cloned and most of the entries in it are ~= 0222. Split it into two parts and register (the largest) one at the read-only root. Signed-off-by:

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:

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:

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.)

Instead of assigning values for the struct cpu_reg's at runtime, we already know these values at compile time. Therefore, we can use designated initializers, to initialize these structures and not have to incur this assignment cost at run-time. Signed-off-by:

To make the bnx2 code more consistent, all instances of RX_COPY_THRESH have been changed to BNX2_RX_COPY_THRESH. Signed-off-by:

Benjamin Li authored
The rx_offset field is set to a constant value and initialized only once. By replacing all references to the rx_offset field, we can eliminate rx_offset from the bnx2 structure. This will save 4 bytes for every bnx2 instance. [Added parentheses to the definition of BNX2_RX_OFFSET, as noted by Ben Hutchings.] Signed-off-by:

Andy Gospodarek <andy@greyhouse.net> found that netconsole would panic when resetting bnx2 devices. >From Andy: "The issue is the bnx2_set_link in bnx2_init_nic will print a link-status message before we are fully initialized and ready to start polling. Polling is currently disabled in this state, but since the __LINK_STATE_RX_SCHED is overloaded to not only try and disable polling but also to make the system aware there is something waiting to be polled, we really have to fix this in drivers. The problematic call is the one to netif_rx_complete as it tries to remove an entry from the poll_list when there isn't one." While this netconsole problem should be fixed separately, we really should not reset the PHY when changing ring sizes, MTU, or other similar settings. The PHY reset causes several seconds of unnecessary link disruptions. Signed-off-by:

Mark Asselstine authored
The use of cli()/sti() within the do/while was a way to ensure interrupts were only disabled for short periods of time while the bulk of the time interrupts were free to occur. The use of the spin lock has eliminated the need to play with interrupts in this way while still allowing for IO to be protected. The remaining 3 sti() calls seem unneeded now that at no other point in the driver is there a call to cli(). Signed-off-by:

The atm_tcp.h uses types from linux/atm.h, but does not include it. It should also use the standard __u## types from linux/types.h rather than the uint##_t types since the former can be found with the kernel already. Same goes for linux/atm.h. The linux/socket.h include there also gets dropped as atm.h does not actually use anything from socket.h. Signed-off-by:

It is possible that the entry in sysfs already exists, one case of this is when a network device is renamed to bonding_masters. Anyway, in this case the proper error path is for device_rename to return an error code, not to generate bogus backtrace and errors. Also, to avoid possible races, the create link should be done before the remove link. This makes a device rename atomic operation like other renames. Signed-off-by:
