There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block. Signed-off-by:

inet_gso_segment() and inet_gso_send_check() are called by skb_mac_gso_segment() under rcu lock, no need to use rcu_read_lock() / rcu_read_unlock() Avoid calling ip_hdr() twice per function. We can use ip_send_check() helper. Signed-off-by:

Remove the specialized code in __tcp_retransmit_skb() that tries to trim any ACKed payload preceding a FIN before we retransmit (this was added in 1999 in v2.2.3pre3). This trimming code was made unreachable by the more general code added above it that uses tcp_trim_head() to trim any ACKed payload, with or without a FIN (this was added in "[NET]: Add segmentation offload support to TCP." in 2002 circa v2.5.33).

The current test works fine in practice. The "amount" variable is actually used as a boolean so negative values or any non-zero values count as "true". However since we don't allow numbers greater than one, let's not allow negative numbers either. Signed-off-by:

When checking statistics or changing parameters on a link, the link_find_link function is used to locate the link with a given name. The complex method of deconstructing the name into local and remote address/interface is error prone and may fail if the interface names contains special characters. We change the lookup method to iterate over the list of nodes and compare the link names. Signed-off-by:

link_cmd_set_value() takes commands for link, bearer and media related configuration. Genereally the function returns 0 when a command is recognized, and -EINVAL when it is not. However, in the switch for link related commands it returns 0 even when the command is unrecognized. This will sometimes make it look as if a failed configuration command has been successful, but has otherwise no negative effects. We remove this anomaly by returning -EINVAL even for link commands. We also rework all three switches to make them conforming to common kernel coding style. Signed-off-by:

Currently, rcv_msg() always returns zero on a packet delivery upcall from net_device. To make its behavior more compliant with the way this API should be used, we change this to let it return NET_RX_SUCCESS (which is zero anyway) when it is able to handle the packet, and NET_RX_DROP otherwise. The latter does not imply any functional change, it only enables the driver to keep more accurate statistics about the fate of delivered packets. Signed-off-by:

tipc_block_bearer() currently takes a bearer name (const char*) as argument. This requires the function to make a lookup to find the pointer to the corresponding bearer struct. In the current code base this is not necessary, since the only two callers (tipc_continue(),recv_notification()) already have validated copies of this pointer, and hence can pass it directly in the function call. We change tipc_block_bearer() to directly take struct tipc_bearer* as argument instead. Signed-off-by:

TIPC 'bearer' exists as an abstract concept, while 'media' is deemed a specific implementation of a bearer, such as Ethernet or Infiniband media. When a component inside TIPC wants to control a specific media, it only needs to access the generic bearer API to achieve this. However, in the current media implementations, the 'bearer' name is also extensively used in media specific function and variable names. This may create confusion, so we choose to replace the term 'bearer' with 'media' in all function names, variable names, and prefixes where this is what really is meant. Note that this change is cosmetic only, and no runtime behaviour changes are made here. Signed-off-by:

tipc_msg_build() now copies message data from iovec to skb_buff using memcpy_fromiovecend(), which doesn't need to be passed the iovec length to perform the copying. So we remove the parameter indicating iovec length in all functions where TIPC messages are built and sent. Signed-off-by:

tipc_msg_build() calls skb_copy_to_linear_data_offset() to copy data from user space to kernel space. However, the latter function does in its turn call memcpy() to perform the actual copying. This poses an obvious security and robustness risk, since memcpy() never makes any validity check on the pointer it is copying from. To correct this, we the replace the offending function call with a call to memcpy_fromiovecend(), which uses copy_from_user() to perform the copying. Signed-off-by:
