* command.h: Remove fields log_stdout and log_syslog from struct host,
since they are just trying to duplicate information in the
zlog_default structure. Note that this fixes a bug since those
fields were not registering any logging that was established
in the initial call to openzlog (this affects only the zebra and
ospf6d daemons). It is probably a bug to turn on any logging by
default in the call to openzlog.
* command.c: (config_write_host) Get logging info from zlog_default
instead of now-removed fields host.log_stdout and host.log_syslog.
(config_log_stdout,no_config_log_stdout) Do not set now-removed field
host.log_stdout, since this info is recorded in zlog_default.
(config_log_file) Use XSTRDUP (instead of strdup) to set host.logfile.
(config_log_syslog,config_log_syslog_facility,no_config_log_syslog)
Do not set now-removed field host.log_syslog, since this info is
recorded in zlog_default.

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

zlog_notice to print the startup message, which now includes
the vty port.

* log.h: Remove several unused fields from struct zlog. Add comments
for other fields, and add one new field syslog_options that is
used in the new syslog_sigsafe implementation.
* log.c: (syslog_sigsafe) New function to send syslog messages in
an async-signal safe way that can be used inside a signal handler.
(syslog_connect) New function to connect to syslog daemon inside a
signal handler. This function supports only systems where /dev/log

|
|
* debug.[ch]: Remove unused files.
* Makefile.am: Remove references to debug.c and debug.h
* ospf_main.c: Remove #include "debug.h" (was not being used, and
lib/debug.h has now been deleted).
|
|
* log.c: (zlog_backtrace) New function to log a backtrace.
(zlog_backtrace_safe) Log a backtrace in an async-signal-safe way.
Unfortunately, this function does not support syslog logging yet.

to stdarg handling.
|
|
* zebra.h: If not C99 and there's no va_copy macro and there is
a __va_copy macro, define va_copy as __va_copy.
|
|
* pid_output.c: (pid_output_lock) Fix 2 bugs: when locking, should
set l_whence to SEEK_SET, not SEEK_END. And after writing new
pid to file, must ftruncate to eliminate any extraneous bytes left
over from the last time a pid was written.

to be safe.
|
|
|
|

as necessary for multiple traversals.
(zlog) Pass only one va_list to vzlog.
(zlog_*,plog_*) Use a macro for boilerplate code; pass only one

|
|

in lib/zebra.h, ensure that RFC3542-required CMSG_SPACE and CMSG_LEN
are defined. Warn if alignment assumptions are made, since they are
i386-centric.
in lib/sockopt.h, declare that sockopt sizes are without
CMSG_SPACE-required padding - just simple sizeof.
in ospfd/ospf_packet.c, simply use CMSG_SPACE
This should remove all instances of CMSG_ALIGN from the source code.
This is a nonstandard, though rational, construct; quagga should use
only those defines in RFC3542.
|
|
* memory.c: (zerror) Use zlog_err instead of fprintf to stderr.
Instead of exiting, log currenty memory usage and then abort.
(log_memstats) New function to log memory statistics, called by
zerror.
(show_memory_all) Loop over new mlists array instead of calling
show_memory_vty separately for each memory_list.

|
|
|
* buffer.c: Add missing include of log.h.
(buffer_flush_available) written is compared against
mostly against unsigned types, only for the writev do we need
signed compare, so declare it as size_t and cast it to ssize_t
just for the error compare when we've called writev.
* buffer.h: Add comment that buffer data sizes really should be
size_t.
|
|
* lib/version.h.in: add autoconf configure_input output var
|
|
* vty.h: Remove fields in struct vty that were related to VTY_CONTINUE
capabilities (that were used only in bgpd/bgp_route.c and are now
removed). Also remove some other fields that were not being
used at all.
* vty.c: (vty_execute) Do not test for obsolete status values VTY_START
and VTY_CONTINUE.
(vty_read) Remove calls to vty->output_func since that was part
of the VTY_CONTINUE infrastructure that has been removed.
(vty_flush) Remove code to support VTY_START and VTY_CONTINUE.
(vty_close) Remove code to cancel vty->t_output thread, since that
thread was never actually used.
* bgp_route.c: Remove all code related to VTY_CONTINUE; this feature
is deprecated because the output did not represent a single point
in time. All output needs to be generated inline and buffered
by the library code.
(route_vty_out,route_vty_out_tag,damp_route_vty_out,
flap_route_vty_out) Remove code to count number of lines of output,
since this was only useful for VTY_CONTINUE behavior.
(bgp_show_callback) Removed.
(bgp_show_table) Remove hooks for VTY_CONTINUE callback support.
As a result, there's a new output_arg argument to this function.
Make function static.
(bgp_show) Make function static and add a new output_arg argument.
Change all functions that call bgp_show or bgp_show_table to
pass the new output_arg argument (that used to be passed inside
vty->output_arg).
* bgp_mplsvpn.c: Remove declarations of functions defined in
bgp_route.c; these declarations belong in bgp_route.h.
* bgp_route.h: Declare 3 global functions used in both bgp_route.c
and in bgp_mplsvpn.c.
|
|
* vty.c: Vtysh connections to daemons should use buffering.
(vty_out) Remove exception for vty_shell_serv, just use buffer_write.
(vty_new) Increase output buffer size to 4096 rounded up to a
multiple of pagesize.
(vtysh_read) After command has been executed and all output buffered,
call buffer_flush_available and schedule further writes if the
buffers are not yet empty.
(vtysh_write) New function to flush output to vtysh when the socket
is writeable.
(vty_event) Added new VTYSH_WRITE event for flushing buffers to vtysh
clients. Also, should save read thread in vty->t_read so the
thread can be cancelled in vty_close.
* buffer.h: In struct buffer_data, remove unused "parent" field.
Convert "unsigned char *data" to "unsigned char data[0]" to save
a malloc. Declare new function buffer_flush_available that works
with non-blocking sockets.
* buffer.c: (buffer_data_new) Use a single malloc now that data is
a variable-size array at end of structure.
(buffer_data_free) Just a single free now that data is part of the
structure.
(buffer_write) Simplify the logic to make behavior more transparent.
(buffer_flush) Decrease b->length as data is written out.
(buffer_flush_vty_all) Decrease b->length as buffers are freed.
(buffer_flush_vty) Decrease b->length as data is written out.
(buffer_flush_available) New function to flush non-blocking sockets.

with CVS trees.
|
|
* sockopt.c: (setsockopt_pktinfo) remove, its unused.
|
|
* thread.c: Use XCALLOC and sizeof the type, not the pointer.
|
|
* smux.c: fix int to size_t compile warnings
|
|
* memory.h: Add MTYPE_THREAD_FUNCNAME and MTYPE_THREAD_STATS
* thread.c: Update stats and funcname alloc/free to use previous
specific memory type defines
|
|
* keychain.c: Convert some more strtoul users to VTY_GET_INTEGER.
|
|
* vty.c: As per Andrew's suggestions..
(vty_serv_un) remove flags.
(vtysh_accept) close socket if we cant set NONBLOCK. Add flags.
|
|
* vty.c: Move setting of sock to O_NONBLOCK from vty_serv_un
to vtysh_accept, where sock is the actual fd we wanted to set to
O_NONBLOCK, ie the /connected/ vtysh unix socket.
|
|
|
|
* zebra.h: reserve ZEBRA_ROUTE_HSLS
|
|
|
|
* sockopt.h: Fix elif that should be an else.
|
|
* command.h: Cleanup the defines a bit, add helper defines and
collapse all defines to use those. Add an attribute field to
cmd_element to support, eg hidden or deprecated commands, add
defun defines for such. All that's left to do is add logic
to command.c to check these attributes... ;)
|
|
* sockopt.c: (setsockopt_pktinfo) unexported
* sockopt.h: Cleanup SOCKOPT_CMSG defines a bit. Add a throwaway
define for SOPT_SIZE_CMSG_IFINDEX_IPV4 for systems which have
neither IP_RECVIF nor IP_PKTINFO (eg openbsd).
|
|
* sockopt.c: (getsockopt_ipv4_ifindex) no ifindex should be 0, not
-1.

ripd might need some more testing though.

initializes connection, and "no smux peer" command terminates it. Fixes
bugzilla #47 and #112.
