* rib.h: (struct rib) Add lock field for refcounting.
* zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra
'master' struct.
* zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC.
* zebra_rib.c: Clean up refcounting of route_node, make struct rib
refcounted and convert rib_process to work-queue. In general,
rib's should be rib_addnode'd and delnode'd to route_nodes, and
these symmetrical functions will manage the locking of referenced
route_node and freeing of struct rib - rather than having users
manage each seperately - with much scope for bugs..
(newrib_free) removed and replaced with rib_lock
(rib_lock) new function, check state of lock and increment.
(rib_unlock) new function, check lock state and decrement. Free
struct rib if refcount hits 0, freeing struct nexthop's, as
newrib_free did.
(rib_addnode) Add RIB to route_node, locking both.
(rib_delnode) Delete RIB from route_node, unlocking each.
(rib_process) Converted to a work-queue work function.
Functional changes are minimal, just arguments, comments and
whitespace.
(rib_queue_add_qnode) Helper function to setup a ribq item.
(rib_queue_add) Helper function, same arguments as old
rib_process, to replace in callers of rib_process.
(rib_queue_qnode_del) ribq deconstructor.
(rib_queue_init) Create the ribq.
(rib_init) call rib_queue_init.
(remainder) Sanitise refcounting of route_node's. Convert to
rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset
to XCALLOC. Remove calls to nexthop_delete and nexthop_free.

* if_ioctl_solaris.c: (if_lookup_linklocal) fix order of args
in ALL_LIST_ELEMENTS_RO macro.
|
|
* zserv.c (zebra_client_read): Fix bug: first read attempt should
read ZEBRA_HEADER_SIZE minus the number of bytes already read.
Improve efficiency by maintaining a calculation of the number
of bytes read instead of calling stream_get_endp multiple times.
If message length is too small, issue a warning message (not debug)
before closing the connection. And also check that message length
is not too big.

about IPv6 nexthops.

status to unsigned here, because we already checked that it isn't
negative or 0.
* rt_netlink.c (netlink_interface_addr): Prefix length belongs to the
address, not to the interface.
* rt_netlink.c (netlink_route_multipath): Fix debug. No useless info
is printed out now and IPv6 info is handeled.
|
|
* lib/vty.c: Improve logging of failures to open vty socket(s).
See bugid #163.
* zebra/zserv.c: print more helpful errors when we fail to successfully
bind and listen on zserv socket. Closes bugzilla #163.

* if_ioctl.c: (interface_list_ioctl) Use if_get_by_name_len.
* if_proc.c: (ifaddr_proc_ipv6) Increase size of ifname buffer to
avoid overflow.
* kernel_socket.c: (ifan_read) Use if_get_by_name_len.
* if.h: Fix comments to reflect that if_lookup_by_name and
if_get_by_name now require the argument strings to be NUL-terminated.
* if.c: (if_lookup_by_name) Compare using strcmp.
(if_get_by_name) Pass strlen(ifname) as 2nd arg to if_create.
|
|
* if.h: (if_lookup_by_name_len, if_get_by_name_len) New functions.
* if.c: (if_lookup_by_name_len, if_get_by_name_len) New functions.
(if_get_by_name) Tighten up code.
(interface) Use new function if_get_by_name_len.
* zclient.c: (zebra_interface_add_read) Use new if_get_by_name_len
function.
(zebra_interface_state_read) Use new if_lookup_by_name_len function.
* kernel_socket.c: (ifm_read) Use new if_lookup_by_name_len function
to save a memcpy.
* if_ioctl_solaris.c: (interface_list_ioctl) Fix subtle bug with new
if_get_by_name_len function.
* ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create.

Fix problems when netlink interfaces are renamed (same ifindex used
for a new interface). Start cleaning up some problems with the way
interface names are handled.
* interface.c: (if_new_intern_ifindex) Remove obsolete function.
(if_delete_update) After distributing the interface deletion message,
set ifp->ifindex to IFINDEX_INTERNAL.
(if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is
IFINDEX_INTERNAL.
(zebra_interface) Check return code from interface_cmd.func.
Do not set internal ifindex values to if_new_intern_ifindex(),
since we now use IFINDEX_INTERNAL for all pseudo interfaces.
* kernel_socket.c: (ifm_read) Fix code and comments to reflect that
all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL.
* rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex.
Detects interface rename events by checking if that ifindex is already
being used. If it is, delete the old interface before assigning
the ifindex to the new interface.
(netlink_interface, netlink_link_change) Call set_ifindex to update
the ifindex.
* if.h: Remove define for IFINDEX_INTERNBASE and add define
IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo-
interfaces should have ifindex set to 0.
(if_new) Remove function.
(if_delete_retain) New function to delete an interface without
removing from iflist and freeing the structure.
(ifname2ifindex) New function.
* if.c: (if_new) Remove function (absorb into if_create).
(if_create) Replace function if_new with call to calloc.
Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error
in assert to check length of interface name. Add error message
if interface with this name already exists.
(if_delete_retain) New function to delete an interface without
removing from iflist and freeing the structure.
(if_delete) Implement with help of if_delete_retain.
(ifindex2ifname) Reimplement using if_lookup_by_index.
(ifname2ifindex) New function to complement ifindex2ifname.
(interface) The interface command should check the name length
and fail with a warning message if it is too long.
(no_interface) Fix spelling in warning message.
(if_nametoindex) Reimplement using if_lookup_by_name.
(if_indextoname, ifaddr_ipv4_lookup) Reimplement using
if_lookup_by_index.
* bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex
to IFINDEX_INTERNAL.
* isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead
of if_delete, since it is generally not safe to remove interface
structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
(zebra_interface_if_lookup) Tighten up code.
* ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function
was commented out. But this is not safe: we should at least update
the ifindex when the interface is deleted. So the new version
updates the interface status and sets ifp->ifindex to
IFINDEX_INTERNAL.
(ospf6_zebra_route_update) Use if_indextoname properly.
* ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface
flags to help with debugging.
* ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex
to IFINDEX_INTERNAL.
(zebra_interface_if_lookup) Make function static. Tighten up code.
* rip_interface.c: (rip_interface_delete) After deleting, set
ifp->ifindex to IFINDEX_INTERNAL.
* ripng_interface.c: (ripng_interface_delete) After deleting, set
ifp->ifindex to IFINDEX_INTERNAL.

it's not for debug.
* rt_netlink.c (netlink_talk): Don't assume we use netlink_cmd
although we do now actually.
* rt_netlink.c (netlink_route, netlink_route_multipath): Always use
netlink_cmd to send messages to the kernel.

* irdp.h: Add prototype for irdp_sock_init, and fix protos for
other irdp_* functions.
* irdp_interface.c: (irdp_if_start) If irdp_sock is negative,
call irdp_sock_init to create the IRDP socket.
(irdp_if_init) Rename to irdp_init().
(get_iflist_ifp) Remove function that is a duplicate of
if_lookup_by_index.
(*) Make many functions static. And remove superfluous "\n" from
several zlog messages.
* irdp_main.c: (irdp_init) Remove function that used to call
irdp_if_init() and irdp_sock_init(), since we will now create
the socket only upon first use.
(irdp_sock_init) Do not update global irdp_sock variable, just
return the fd and assume that the caller will do so. If setsockopt
calls fail, close the socket before returning -1.
(*) Make many functions static.
* irdp_packet.c: Initialize irdp_sock to -1.
(irdp_read_raw) Call standard library function if_lookup_by_index
instead of get_iflist_ifp.
(irdp_recvmsg) Should be static, not global.

* rt_netlink.c: (netlink_link_change) If the status of an
operative interface changes (e.g. MTU changes), the client
daemons should be notified by calling zebra_interface_up_update.
Previously, the information was being updated in zebra's
interface structure, but the clients were not notified of
changes to an operative interface.
* ospf_zebra.c: (ospf_interface_state_up) If the MTU of an operative
interface changes, print a debug message and call ospf_if_reset()
to simulate down/up on the interface.
* ospf_interface.h: Declare new function ospf_if_reset().
* ospf_interface.c: (ospf_if_reset) New function to call ospf_if_down
and ospf_if_up for all ospf interfaces attached to an interface.

* interface.c, interface.h, rtadv.c, rtadv.h: extensions to Neighbor
discovery for Mobile IPv6.

* zserv.c: Must include network.h and buffer.h for non-blocking I/O.
Remove global message_queue and t_write (need separate buffering for
each client).
(zebra_server_dequeue,zebra_server_enqueue) Remove functions
related to old buggy buffering code.
(zserv_delayed_close) New thread callback function to delete a client.
(zserv_flush_data) New thread callback function to flush buffered
data to client.
(zebra_server_send_message) Rewritten to use buffer_write (so
buffering of writes and non-blocking I/O work properly).
(zsend_interface_add,zsend_interface_delete,zsend_interface_address,
zsend_interface_update) Return 0 instead of -1 if !client->ifinfo
(this is not really an error). Return value from
zebra_server_send_message.
(zsend_route_multipath,zsend_ipv4_nexthop_lookup,
zsend_ipv4_import_lookup) Return value from zebra_server_send_message.
(zsend_ipv6_nexthop_lookup) Fix scope to static, and return value
from zebra_server_send_message.
(zsend_router_id_update) Must use zebra_server_send_message instead
of deprecated writen function. Return 0 instead of -1 if this client
is not subscribed to router-id updates (since this is not really
an error).
(zread_interface_add) Change type to static int. If
zsend_interface_add fails or zsend_interface_address fails, return -1
immediately (since the client has had an I/O error).
(zread_interface_delete,zread_ipv4_add,zread_ipv4_delete,
zread_ipv6_add,zread_ipv6_delete,zread_router_id_delete) Return 0
to indicate success.
(zread_ipv4_nexthop_lookup) Return value from
zsend_ipv4_nexthop_lookup.
(zread_ipv4_import_lookup) Return value from zsend_ipv4_import_lookup.

socket non-blocking using the set_nonblocking function.
(config_write_forwarding) Fix scope to static.
(zebra_init) Remove initialization code for old buggy write buffering.
* zserv.h: Add 2 new fields to struct zserv: struct buffer *wb
(to enable buffered writes with non-blocking I/), and
struct thread *t_suicide to support delayed close on I/O
errors.
* router-id.h: Remove prototypes for zread_router_id_add and
zread_router_id_delete (their scope should be static to zserv.c).

* redistribute.c: (zebra_check_addr,is_default,
zebra_redistribute_default,zebra_redistribute) Fix scope to be static.

* zserv.c: (zebra_accept) Comment out setting of socket to NONBLOCK
for now, as we dont actually deal with with resending.... See
bugzilla #122, fix from wawa@yandex-team.ru (Vladimir Ivanov).
* kernel_socket.c: (routing_socket) ditto.
|
|
* configure.ac: Added test for broken CMSG_FIRSTHDR macro
(relevant for Solaris 8 and unpatched Solaris 9, don't know
whether other platforms are affected).
* zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether
config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined
by the configure test program).
* sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead
of CMSG_FIRSTHDR.
* rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR
instead of CMSG_FIRSTHDR.
* ripd.c: (rip_recvmsg) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR.

* connected.c: (connected_add_ipv4) Limit warning about /32 addresses
with no peer specified to PtP interfaces only.
|

Note two warnings in comments. The serious one is that struct
interface->ifindex probably needs to be signed, ssince we store and
compare to -1.

* *.c: Change level of debug messages to LOG_DEBUG.
|
|
* bgp_main.c: (main) The 2nd argument to openzlog has been removed.
* isis_main.c: (main) The 2nd argument to openzlog has been removed.
* ospf6_main.c: (main) The 2nd argument to openzlog has been removed.

not running as a daemon.
* ospf_main.c: (main) The 2nd argument to openzlog has been removed.
* rip_main.c: (main) The 2nd argument to openzlog has been removed.
* ripng_main.c: (main) The 2nd argument to openzlog has been removed.
* main.c: (main) The 2nd argument to openzlog has been removed.
So stdout logging will no longer be enabled by default.
* irdp_main.c: (irdp_finish) Reduce severity of shutdown message
from LOG_WARNING to LOG_INFO.
* vtysh.c: Make several functions static instead of global.
Added several commands to support destination-specific logging levels.
(vtysh_completion) This function is unused, so comment it out.
* basic.texi: Document new logging features. Separate basic config
commands from basic VTY commands.
* log.h: Replace struct zlog flags and maskpri fields with maxlvl
array to support individual logging levels for each destination.
Remove the 2nd argument to openzlog since the default logging config
should be standardized inside the library. Replaced the
zlog_set_flag and zlog_reset_flag functions with zlog_set_level.
And zlog_set_file now requires an additional log_level argument.
Declare zlog_proto_names for use inside command.c in the
"show logging" command. Added defines useful for command
construction.
* log.c: (vzlog) Decide where to send the message based on the
individual logging levels configured for each destination.
Remove support for ZLOG_STDERR since it was never actually used.
Support record-priority for terminal monitors.
(zlog_signal,zlog_backtrace_sigsafe) Support destination-specific
logging levels. Remove stderr support (was never used). Added
support for terminal monitor logging.
(_zlog_assert_failed) Increase message severity to LOG_EMERG.
(openzlog) Remove 2nd argument since default config should be
standardized in library. By default, terminal monitoring
is set to debug, and all other logging is disabled.
(zlog_set_flag,zlog_reset_flag) Removed.
(zlog_set_level) New function to replace zlog_set_flag and
zlog_reset_flag. Supports destination-specific logging levels.
(zlog_set_file,zlog_reset_file) Support file-specific logging level.
(zlog_rotate) Log an error message if fopen fails, and support
new file-specific logging level.
* command.h: Change DEFUN_CMD_FUNC_DECL and DEFUN_CMD_FUNC_TEXT so that
command functions will be static instead of global. Remove
declarations for config_exit and config_help. Define new macros
DEFUNSH_ATTR, DEFUNSH_HIDDEN, and DEFUNSH_DEPRECATED so we can
have deprecated commands in vtysh. Similarly, for completeness,
define macros ALIAS_SH, ALIAS_SH_HIDDEN, and ALIAS_SH_DEPRECATED.
Also, fix bug in ALIAS_ATTR macro (didn't matter because it
was never used).
* command.c: Make many functions static instead of global.
(facility_name,facility_match,level_match) New functions
to support enhanced destination-specific logging levels.
(config_write_host) Support new destination-specific logging levels.
(config_logmsg) Added new "logmsg" command to help test logging
system.
(show_logging) Added "show logging" command to show the current
configuration of the logging system.
(config_log_stdout_level) Support explicit stdout logging level.
(no_config_log_stdout) Now takes optional LEVEL arg.

"log stdout <level>", "log monitor", "log monitor <level>",
"no log monitor", "log file <filename> <level>",
"no log file <filename> <level>", "log syslog <level>",
"log facility", and "no log facility".
* vty.h: Added a "level" argument to vty_log so it can support
"log record-priority". Declare new function vty_log_fixed for
use in signal handlers.
* vty.c: (vty_log,vty_log_out) Added a "level" argument to support
"log record-priority" for vty terminal monitors.
(vty_down_level) Use config_exit_cmd.func instead of calling
config_exit directly (since command functions will now be static
instead of global).
(vty_log_fixed) New function to send terminal monitor messages
from inside a signal handler.

* bgp_main.c: (sigint) Use zlog_notice for termination message.
(main) Use zlog_notice for startup announcement.
* isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
(terminate) This function should be static, not global.

ifdef ZEBRA_VERSION.
* version.h.in: Remove declaration for pid_output_lock, this function
is now static, not global.
* pid_output.c: (pid_output_lock) This function should be static, not
global. And remove "old umask" error message, since it was really
an unimportant debug message, not an error.
(pid_output) Need to declare static function pid_output_lock.
* ospf6_main.c: (sigint,sigterm) Use zlog_notice for termination
message.
(main) Remove commented-out call to pid_output_lock (which should
never be called other than from inside pid_output). And use
zlog_notice to print the startup message, which now includes
the vty port.
* ospf_main.c: (sigint) Use zlog_notice for termination message.
(main) Issue a startup announcement using zlog_notice.
* rip_main.c: (sigint) Use zlog_notice for termination message.
(main) Add a startup announcement using zlog_notice.
* ripng_main.c: (sighup) Remove spurious terminating message.
(sigint) Use zlog_notice for termination message.
(main) Issue a startup announcement using zlog_notice.

compare it to received checksum. Check data length against
claimed length in header.
Always use ntoh.. when accessing addresses, even when the
comparison happens to be endian-safe.
(send_packet) minor style isues. Use
sockopt_iphdrincl_swab_htosys.
