The hash size is doubled when it needs to grow and compared against hash_max. The >= comparison will limit the hash table size to half of what is expected i.e. the default 512 hash_max will not allow the hash table to grow larger than 256. Also print the hash table limit instead of the desirable size when the limit is reached. Signed-off-by: NThomas Graf <tgraf@suug.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Userspace implementations of network routing protocols sometimes need to tell RA-originated IPv6 routes from other kernel routes to make proper routing decisions. This makes most sense for RA routes with nexthops, namely, default routes and Route Information routes. The intended mean of preserving RA route origin in a netlink message is through indicating RTPROT_RA as protocol code. Function rt6_fill_node() tried to do that for default routes, but its test condition was taken wrong. This change is modeled after the original mailing list posting by Jeff Haran. It fixes the test condition for default route case and sets the same behaviour for Route Information case (both types use nexthops). Handling of the 3rd RA route type, Prefix Information, is left unchanged, as it stands for interface connected routes (without nexthops).

Lenght field should be encoded using big endian byte order, such as intend in the specs. As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues.

John Linville says: ==================== Several drivers see updates: mwifiex, ath9k, iwlwifi, brcmsmac, wlcore/wl12xx/wl18xx, and a handful of others. The bcma bus got a lot of attention from Hauke Mehrtens. The cfg80211 component gets a flurry of patches for multi-channel support, and the mac80211 component gets the first few VHT (11ac) and 60GHz (11ad) patches. This also includes the removal of the iwmc3200 drivers, since the hardware never became available to normal people. Additionally, the NFC subsystem gets a series of updates. According to Samuel, "Here are the interesting bits: - A better error management for the HCI stack. - An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are now reserved only when there's a client for it. - Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and write NFC tags and also establish a p2p link with this dongle now. - A few LLCP fixes." Finally, this includes another pull of the fixes from the wireless tree in order to resolve some merge issues. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The internal log buffer handling functions can now safely be removed since there is no code using it anymore. Requests to interact with the internal tipc log buffer over netlink (in config.c) will report 'obsolete command'. This represents the final removal of any references to a struct print_buf, and the removal of the struct itself. We also get rid of a TIPC specific Kconfig in the process. Finally, log.h is removed since it is not needed anymore.

The tipc_printf is renamed to tipc_snprintf, as the new name describes more what the function actually does. It is also changed to take a buffer and length parameter and return number of characters written to the buffer. All callers of this function that used to pass a print_buf are updated. Final removal of the struct print_buf itself will be done synchronously with the pending removal of the deprecated logging code that also was using it. Functions that build up a response message with a list of ports, nametable contents etc. are changed to return the number of characters written to the output buffer. This information was previously hidden in a field of the print_buf struct, and the number of chars written was fetched with a call to tipc_printbuf_validate. This function is removed since it is no longer referenced nor needed. A generic max size ULTRA_STRING_MAX_LEN is defined, named in keeping with the existing TIPC_TLV_ULTRA_STRING, and the various definitions in port, link and nametable code that largely duplicated this information are removed. This means that amount of link statistics that can be returned is now increased from 2k to 32k. The buffer overflow check is now done just before the reply message is passed over netlink or TIPC to a remote node and the message indicating a truncated buffer is changed to a less dramatic one (less CAPS), placed at the end of the message.

tipc_printf was previously used both to construct debug traces and to append data to buffers that should be sent over netlink to the tipc-config application. A global print_buffer was used to format the string before it was copied to the actual output buffer. This could lead to concurrent access of the global print_buffer, which then had to be lock protected. This is simplified by changing tipc_printf to append data directly to the output buffer using vscnprintf. With the new implementation of tipc_printf, there is no longer any risk of concurrent access to the internal log buffer, so the lock (and the comments describing it) are no longer strictly necessary. However, there are still a few functions that do grab this lock before resizing/dumping the log buffer. We leave the lock, and these functions untouched since they will be removed with a subsequent commit that drops the deprecated log buffer handling code Signed-off-by: NErik Hugne <erik.hugne@ericsson.com> Signed-off-by: NJon Maloy <jon.maloy@ericsson.com> Signed-off-by: NPaul Gortmaker <paul.gortmaker@windriver.com>

The link queue traces and packet level debug functions served a purpose during early development, but are now redundant since there are other, more capable tools available for debugging at the packet level. The TIPC_DEBUG Kconfig option is removed since it does not provide any extra debugging features anymore.

All messages should go directly to the kernel log. The TIPC specific error, warning, info and debug trace macro's are removed and all references replaced with pr_err, pr_warn, pr_info and pr_debug. Commonly used sub-strings are explicitly declared as a const char to reduce .text size. Note that this means the debug messages (changed to pr_debug), are now enabled through dynamic debugging, instead of a TIPC specific Kconfig option (TIPC_DEBUG).

This patch is meant to help improve performance by reducing the number of locked operations required to allocate a frag on x86 and other platforms. This is accomplished by using atomic_set operations on the page count instead of calling get_page and put_page. It is based on work originally provided by Eric Dumazet. In addition it also helps to reduce memory overhead when using TCP. This is done by recycling the page if the only holder of the frame is the netdev_alloc_frag call itself. This can occur when skb heads are stolen by either GRO or TCP and the driver providing the packets is using paged frags to store all of the data for the packets.
