* (global) update all c files to match the lib/vector.h rename of (struct vector).active to max, and vector_max macro to vector_active. * lib/vector.h: Rename to (struct vector).max to slightly less confusing active, for the number of active slots, distinct from allocated or active-and-not-empty. Rename vector_max to vector_active for same reason.
2005-03-142005-03-14 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (various) Fix indentation and other whitespace.
2005-03-142005-03-14 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (sort_node) use vector_max instead of referencing (struct vector *)->max directly. Test that vector_max is > 0 before using it to calculate an index. Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_cmdsize) Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_filter_by_completion) ditto (cmd_filter_by_string) ditto (is_cmd_ambiguous) ditto (cmd_describe_command_real) Change index integers to unsigned. Test that vector_max is > 0 before using it to calculate an index. Return immediately with CMD_ERR_NO_MATCH if vline has no active slots. Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_complete_command_real) ditto. (cmd_execute_command_strict) Fixup vector loop to be conditional on non-null slot.

* ospf_lsa.c: (ospf_lsa_refresh_walker) If the system clock jumps backward, then current time may be less than ospf->lsa_refresher_started. This was causing invalid values for ospf->lsa_refresh_queue.index resulting in infinite loops. Problem fixed by casting the expression to unsigned before taking the modulus. [backport candidate]
2005-03-13 * zebra/interaface.c: "show interface description" commandhasso
implemented.
2005-03-122005-03-12 Paul Jakma <paul.jakma@sun.com>paul

2005-03-122005-03-12 Paul Jakma <paul@dishone.st>paul
* rt_netlink.c: (netlink_route_multipath) dont set equalise flag. No stock Linux kernel has ever supported it, and even if it had
2005-03-092005-03-09 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (config_list_cmd) Don't list hidden or deprecated commands, hiding these from tab completion is still to be done.
2005-03-092005-03-09 Paul Jakma <paul.jakma@sun.com>paul
* command.c: Undo commit of sign warning fix and hidden command in list_cmd. Sign warning is more subtle. list_cmd on its own will be committed after.
2005-03-09 * vtysh_config.c: Move password commands to the AAA_NODE. Ithasso
quarantees that they will appear after SERVICE_NODE to make sure that encrypted passwords will work ("service password-encryption" command). [backport candidate]
2005-03-082005-03-08 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (no_banner_motd_cmd) use XFREE. * vty.c: (vty_hello) fix the indentation and comment.
2005-03-082005-03-08 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (cmd_describe_command_real) sign compile warning fix (cmd_complete_command_real) ditto. (config_list_cmd) Don't list hidden or deprecated commands, hiding these from tab completion is still to be done. * command.h: cmd attr enum should start at 1.
2005-03-082005-03-08 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (banner_motd_file_cmd) use XSTRDUP/XFREE * vty.c: (vty_hello) suggestions from Andrew, read by line and stub out trailling non-printable characters on each line thus allowing us to specify VTY_NEWLINE to vty_out.
2005-03-082005-03-08 Jeroen Massar <jeroen@unfix.org>paul

* 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. (zebra_read_ipv6) Remove unused function. (zread_ipv6_nexthop_lookup) Return value from zsend_ipv6_nexthop_lookup. (zread_router_id_add) Return value from zsend_router_id_update. (zebra_client_close) Call buffer_free(client->wb) and thread_cancel(client->t_suicide). (zebra_client_create) Allocate client->wb using buffer_new. (zebra_client_read) Support non-blocking I/O by using stream_read_try. Use ZEBRA_HEADER_SIZE instead of 3. (zebra_accept) Fix bug: reset accept thread at top. Make client 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).

* {vty.h,vty.c}: Remove vty_finish (duplicate of vty_reset). * isis_main.c: (reload) Call vty_reset instead of vty_finish (both functions were exactly the same).
2005-02-232005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* ospfd.h: Add new field struct stream *ibuf to struct ospf. * ospfd.c: (ospf_new) Check return code from ospf_sock_init. Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1). (ospf_finish) Call stream_free(ospf->ibuf. * ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then pass it to ospf_recv_packet for use in receiving the packet (instead of allocating a new stream for each packet received). Eliminate all calls to stream_free(ibuf). (ospf_recv_packet) The struct stream *ibuf is now passed in as an argument. No need to use recvfrom to peek at the packet header (to see how big it is), just use ospf->ibuf which is always large enough (this eliminates a system call to recvfrom). Therefore, no need to allocate a stream just for this packet, and no need to free it when done.
2005-02-232005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* buffer.h: Make the struct buffer and struct buffer_data structures private by moving them inside buffer.c. Add comments for all functions. Rename buffer_write as buffer_put (to be more consistent with the buffer_putc and buffer_putstr functions). Declare a new buffer_write function that is used to write data to a file descriptor and/or add it to the buffer queue. Remove unused function buffer_flush_vty_all. Create a new enum typedef buffer_status_t to be used as the return code for all buffer_flush* functions and buffer_write. * buffer.c: The struct buffer and struct buffer_data declarations are now private to this file. In conjunction with that, remove some unnecessary fields: struct buffer (alloc, unused_head, unused_tail, length), struct buffer_data (prev). (buffer_data_new) Removed: functionality incorporated into buffer_add. (buffer_data_free) Removed: use a macro BUFFER_DATA_FREE instead. (buffer_new) Use calloc instead of malloc + memset(zero). Supply an appropriate default size if the specified size is 0. (buffer_free) Eliminate code duplication by calling buffer_reset to free the contents of the buffer (and remove unused code related to unused_head). (buffer_empty,buffer_putc,buffer_putstr) Aesthetic change (make more compact). (buffer_reset) Use macro BUFFER_DATA_FREE. No need to set alloc and length to 0 (these fields have been removed). (buffer_add) Fix scope to be static. Call XMALLOC directly instead of calling removed buffer_data_new function. Simplify the logic (since it's now a singly-linked list instead of doubly-linked). (buffer_write) Renamed to buffer_put. Change to void, since return code of 1 was meaningless. No need to adjust length field, since it has been removed. (buffer_putw,buffer_flush,buffer_flush_vty_all,buffer_flush_vty) Remove unused functions. (buffer_flush_all) Rewrite using buffer_flush_available to eliminate a possible failure mode if IOV_MAX is less than the number of buffers on the queue. (buffer_flush_window) Incorporate logic from buffer_flush_vty. Log an error message if there is a writev error. (buffer_flush_available) Be more paranoid: check for case where buffer is already empty. Use new ERRNO_IO_RETRY macro, and use new enum for return codes. Simplify deletion logic (since it's now a singly-linked list). (buffer_write) New function for use with non-blocking I/O. * vty.h: Replace the struct vty sb_buffer field with a fixed-size (5-character) sb_buf field and an sb_len field, since using a struct buffer was inappropriate for this task. Add some useful comments about telnet window size negotiation. * vty.c: Include <arpa/telnet.h> (no longer included by zebra.h). Remove VTY_OBUF_SIZE (instead use buffer_new default size). Make telnet_backward_char and telnet_space_char static const. (vty_out) Replace buffer_write with buffer_put. (vty_log_out) Check for I/O errors. If fatal, close the vty session. Consolidate 3 separate writes into a single write call. (vty_will_echo,vty_command,vty_next_line,vty_previous_line, vty_end_config,vty_describe_fold,vty_clear_buf,vty_serv_sock_addrinfo, vty_serv_sock_family,vty_serv_un,vty_use_backup_config,exec_timeout, vty_config_write,vty_save_cwd) Fix scope to static. (vty_new) Let buffer_new use its default buffer size. (vty_write) Fix signature: 2nd arg should be const char *. Replaced buffer_write with buffer_put. (vty_telnet_option) Fix minor bug (window height or width greater than 255 was broken). Use sb_buf and sb_len instead of removed sb_buffer (which was being used improperly). (vty_read) On error, use ERRNO_IO_RETRY to decide whether it's fatal. If the error is fatal, call buffer_reset so vty_close does not attempt to flush the data. Use new sb_buf and sb_len instead of sb_buffer to store the SB negotiation string. (vty_flush) When vty->lines is 0, call buffer_flush_available instead of buffer_flush_window. Look at the return code from buffer_flush to detect I/O errors (and in that case, log an error message and close the vty). (vty_create) Fix scope to static. Initialize sb_len to 0 instead of creating sb_buffer. (vty_accept) Set socket nonblocking. (vtysh_accept) Use new set_nonblocking function instead of calling fcntl directly. (vtysh_flush) New function called from vtysh_read (after command execution) and from vtysh_write. This flushes the buffer and reacts appropriately to the return code (by closing the vty or scheduling further flushes). (vtysh_read) Check whether error is fatal using ERRNO_IO_RETRY. If not, just try again later. Otherwise, call buffer_reset before calling vty_close (to avoid trying to flush the buffer in vty_close). Fix logic to allow case where a command does not arrive atomically in a single read call by checking for the terminating NUL char. (vtysh_write) Use new vtysh_flush helper function. (vty_close) No need to call buffer_empty, just call buffer_flush_all in any case (it will check whether the buffer is empty). Do not free sb_buffer (since it has been removed). (vty_log_fixed) Use writev instead of write. * zebra.h: Do not include <arpa/telnet.h>, since this is used only by lib/vty.c.

2005-02-172005-02-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* ospf_packet.c: (ospf_recv_packet) If there is somehow a runt packet in the queue, it must be discarded. Improve warning messages. Fix scope to static. (ospf_read) Fix bug: should reset the read thread in all cases to make sure we continue to get incoming messages.

(stream_recvmsg) Should return -1 if the stream is too small to contain the data.
2005-02-162005-02-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* network.c: (set_nonblocking) Should check return code from fcntl(F_GETFL).
