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). The latter will be phased out completely Signed-off-by: Erik Hugne <erik.hugne@ericsson.com> Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> [PG: use pr_fmt as suggested by Joe Perches <joe@perches.com>] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> --- net/tipc/bcast.c | 2 +- net/tipc/bearer.c | 52 ++++++++++++---------- net/tipc/config.c | 6 +-- net/tipc/core.c | 13 +++--- net/tipc/core.h | 12 +---- net/tipc/discover.c | 4 +- net/tipc/handler.c | 4 +- net/tipc/link.c | 116 ++++++++++++++++++++++++++----------------------- net/tipc/name_distr.c | 25 ++++++----- net/tipc/name_table.c | 40 ++++++++--------- net/tipc/net.c | 8 ++-- net/tipc/netlink.c | 2 +- net/tipc/node.c | 22 +++++----- net/tipc/node_subscr.c | 3 +- net/tipc/port.c | 8 ++-- net/tipc/ref.c | 10 ++--- net/tipc/socket.c | 10 ++--- net/tipc/subscr.c | 14 +++--- 18 files changed, 177 insertions(+), 174 deletions(-) (limited to 'net/tipc/bcast.c') diff --git a/net/tipc/bcast.c b/net/tipc/bcast.c index d9df34fbd7c..fef3689bcf2 100644 --- a/net/tipc/bcast.c +++ b/net/tipc/bcast.c @@ -880,7 +880,7 @@ void tipc_port_list_add(struct tipc_port_list *pl_ptr, u32 port) if (!item->next) { item->next = kmalloc(sizeof(*item), GFP_ATOMIC);

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.
