* | | Add signal functions to lib/qpthreads.cChris Hall (GMCH)2009-12-032-0/+60
| | | | | | | | | | | | Adding qpt_thread_sigmask() and qpt_thread_signal().
* | | Allow floating argument for QTIME(s) in lib/qtime.hChris Hall (GMCH)2009-12-031-1/+2
| | | | | | | | | | | | | | | Changed casts around so that the seconds argument can be a floating point value. So that, in particular, QTIME(2.33) works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lib.c: use a mutex to protect all public methods. Replaced code in command.c etc that modified zlog_default directly with interlocked getters and setters. Requires that vty_log in vty.c handles its own pthread safety TBA. privs.c: use a mutex to protect all public methods. Counts RAISE and LOWER so that privilege stays RAISED until all pthreads have lowered. Improved messages in test-privs.c
* | | | Pthreads infrastructure -- initial commitChris Hall (GMCH)2009-12-029-5/+1818

Implicitly documents the sub-set of Pthreads being used. Provides error checking for a number of functions which may return errors, but are not generally expected to and for whom an error is treated as fatal. Could be modified to "null out" the use of Pthreads. New files: lib/qtime.c & .h Defines a 64-bit integer time value which is a lot easier to handle than the usual timespec and timeval structures. (C99 requires a 64-bit integer.) Provides front ends for gettimeofday() & clock_gettime() which return 64-bit time value. Also conversions to and from timespec and timeval. Provides a monotonic clock for when CLOCK_MONOTONIC is not available. (This is based on code from Joakim Tjernlund.) New files: lib/heap.c & .h Implements a heap data structure closely allied to the vector. This will be used for timer handling. Modified: lib/memtypes.c New memory types for qpthreads structures and for the heap. Modified: lib/zassert.h Added explicit "passert" == assert which is not subject to NDEBUG. Added explicit "nassert" == assert which is subject to NDEBUG. Added zabort, zabort_errno and zabbort_err for when something has gone fatally wrong. (Require changes to lib/log.c which are TBD.)

* | Fix return values for str2prefix_ipv4 and str2prefix_ipv6Chris Hall (GMCH)2009-11-261-32/+60
| | | | | | | | | | | | There appears to be some divergence of opinion over the return values from these functions. This change makes the return == 1 if OK, and 0 otherwise. This is consistent with all usage.
* | Upgrade Prefix-List & BGP Community-List handlingChris Hall (GMCH)2009-11-264-1081/+1352
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Affects: lib/plist.c & .h and bgpd/bgp_clist.c & .h With very long prefix-lists the repeated scanning of the linked list of prefix_list_entry slowed things down (scaled O(n**2)). For lists of 10,000 or more entries this could consume several *minutes* while reading a configuration file. This is a substantial re-working of the code, making use of new facilities introduced in lib/symtab and lib/vector. The prefix-list names are held in a symbol table. The addition of entries to a prefix-list uses binary-chop searches rather than linear list scans. For bgpd, all references to prefix-lists are replaced by symbol table references. The peer_prefix_list_update function is called every time a prefix-list changes. This used to run through every possible reference to a prefix-list to see if its address needed updating. For other daemons, the old interfaces have been preserved. The prefix match code has been stream-lined a little. The BGP community-list and extcommunity-list handling has also been updated to use a symbol table to hold the names. This improves the processing of route-maps, which look-up the list by name each time it is used. (In the longer term, this should be replaced by the use of symbol references.) Other files affected: bgpd/bgpd.c & .h bgpd/bgp_route.c & .h bgpd/bgp_packet.c bgpd/bgp_vty.c updated to use prefix list references & community list symbols. symtab.c & .h small change to symbol_dec_ref & symbol_zero_ref to return NULL if reference count goes to zero, and the symbol otherwise.
* | Add functions to lib/vty.c & .hChris Hall (GMCH)2009-11-242-5/+35
| | | | | | | | | | | | | | | | | | Added: vty_puts -- output string vty_out_newline -- output newline of appropriate form vty_out_indent -- output given number of spaces Made (vty == NULL) a synonym for VTY_TERM, for vty_out and related functions.
* | Introduce lib/symtab.c & .hChris Hall (GMCH)2009-11-244-2/+1502
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are two brand new files. They provide a "Symbol Table" data structure, which maps symbol "names" to symbol "values. (Inside the dta structure is a hash table.) There is also support for managing references to symbols, and the ability to visit all references to a symbol when its value is set or unset. Other files affected: lib/Makefile.am -- to add the new files. lib/memtypes.c -- additional memory types for symbol table stuff
* | Upgrade lib/vector.c & .hChris Hall (GMCH)2009-11-247-287/+1539
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This upgrade maintains the existing vector operations, but changes the underlying mechanisms. It then adds a number of new functions, extending the operations on vectors. The "struct vector" is redefined, which affects only some code in lib/command.c -- which pokes around inside what should be treated as a private data structure. Pro tem this is supported by a macro. The constant VECTOR_MIN_SIZE has been removed -- if there is a minimum size that should be enforced by the vector code. New functions include: vector_insert_item -- insert item, moving existing items vector_move_item -- move item from place to place in vector vector_delete_item -- delete item and close up gap vector_reverse -- reverse order of vector vector_push_item -- simple push vector_pop_item -- simple pop vector_insert -- insert 1 or more NULL items, moving existing items vector_delete -- delete 1 or more items and close up gap vector_bsearch -- perform binary search on vector vector_sort -- qsort vector vector_copy_here -- make copy of body of vector vector_move_here -- move body of vector vector_copy_append -- append copy of vector to end of another vector_move_append -- move body of vector to the end of another vector_copy_extract -- copy part of one vector to another vector_move_extract -- move part of one vector to another vector_copy_splice -- copy part of one vector to replace part of another, taking a copy of the replaced part vector_move_splice -- move part of one vector to replace part of another, taking a copy of the replaced part vector_copy_replace -- copy part of one vector to replace part of another vector_move_replace -- move part of one vector to replace part of another vector_discard -- discard body of vector vector_chop -- discard any unused memory in body of vector vector_decant -- decant vector to new body Other files affected: command.c: -- removal of VECTOR_MIN_SIZE -- use of vector_sort() -- use of VECTOR_INDEX to poke around inside vector (removing this is TODO) memtypes.c & memory.c -- updating names and comments for vectors vty.c -- removal of VECTOR_MIN_SIZE memory.h -- added SIZE(t,n) macro -- (sizeof(t) * (n))
* lib/trivial: str2prefix checks return of inet_pton in fragile wayPaul Jakma2009-08-281-2/+2
| | | | | * prefix.c: (str2prefix_ipv6) inet_pton succesful return is presumed to be 1, rather than the "not zero" the man page describes - seemed fragile.
* lib: if_lookup_by_name should be more robust to null argumentPaul Jakma2009-08-281-7/+9
| | | | * if.c: (if_lookup_by_name) shouldn't crash just cause we got a NULL name
* bgpd: start listener on first instanceStephen Hemminger2009-07-281-0/+1
| | | | | | | | | | | | | Start BGP listener only after first instance is started. This helps the security if BGP is not used but daemon is started. It also addresses some issues like MD5 not working on listener unless IPV6 configured (because listener was not in list); as well as compiler warnings. * bgp_network.c: (bgp_listener) listen socket creation consolidated here (bgp_socket) Use bgp_listener * bgpd.c: (bgp_get) call bgp_socket on creation of first struct bgp. (bgp_init) remove bgp_socket call. * memtypes.c: Add MTYPE_BGP_LISTENER
* [bgpd] Stability fixes including bugs 397, 492Chris Caputo2009-07-1912-23/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've spent the last several weeks working on stability fixes to bgpd. These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community. This code has been production tested, in non-route-server-client mode, on a linux 32-bit box and a 64-bit box. Release/reset functions, used by bgp_exit(), added to: bgpd/bgp_attr.c,h bgpd/bgp_community.c,h bgpd/bgp_dump.c,h bgpd/bgp_ecommunity.c,h bgpd/bgp_filter.c,h bgpd/bgp_nexthop.c,h bgpd/bgp_route.c,h lib/routemap.c,h File by file analysis: * bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released. * bgpd/bgp_attr.c: #if removed uncalled cluster_dup(). * bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from bgp_exit(). * bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and also fix memory leak. * bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees allocations made as part of bgpd initialization and, to some extent, configuration. If "debug bgp" is configured, memory stats are printed as described above. * bgpd/bgp_nexthop.c: zclient_new() already allocates stream for ibuf/obuf, so bgp_scan_init() shouldn't do it too. Also, made it so zlookup is global so bgp_exit() can use it. * bgpd/bgp_packet.c: bgp_capability_msg_parse() call to bgp_clear_route() adjusted to use new BGP_CLEAR_ROUTE_NORMAL flag. * bgpd/bgp_route.h: Correct reference counter "lock" to be signed. bgp_clear_route() now accepts a bgp_clear_route_type of either BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. * bgpd/bgp_route.c: - bgp_process_rsclient(): attr was being zero'ed and then bgp_attr_extra_free() was being called with it, even though it was never filled with valid data. - bgp_process_rsclient(): Make sure rsclient->group is not NULL before use. - bgp_processq_del(): Add call to bgp_table_unlock(). - bgp_process(): Add call to bgp_table_lock(). - bgp_update_rsclient(): memset clearing of new_attr not needed since declarationw with "= { 0 }" does it. memset was already commented out. - bgp_update_rsclient(): Fix screwed up misleading indentation. - bgp_withdraw_rsclient(): Fix screwed up misleading indentation. - bgp_clear_route_node(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_node_queue_del(): Add call to bgp_table_unlock() and also free struct bgp_clear_node_queue used for work item. - bgp_clear_node_complete(): Do peer_unlock() after BGP_EVENT_ADD() in case peer is released by peer_unlock() call. - bgp_clear_route_table(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. Use struct bgp_clear_node_queue to supply data to worker. Add call to bgp_table_lock(). - bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL. Bug 397 fixes: - bgp_default_originate() - bgp_announce_table() * bgpd/bgp_table.h: - struct bgp_table: Added reference count. Changed type of owner to be "struct peer *" rather than "void *". - struct bgp_node: Correct reference counter "lock" to be signed. * bgpd/bgp_table.c: - Added bgp_table reference counting. - bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if set. - bgp_unlock_node(): Added assertion. - bgp_node_get(): Added call to bgp_lock_node() to code path that it was missing from. * bgpd/bgp_vty.c: - peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment to owner. Handle failure gracefully. - peer_rsclient_unset_vty(): Add call to bgp_clear_route() with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. * bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it. * bgpd/bgpd.c: - peer_lock(): Allow to be called when status is "Deleted". - peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to bgp_clear_route() call. - peer_delete(): Common variable listnode pn. Fix bug in which rsclient was only dealt with if not part of a peer group. Call bgp_clear_route() for rsclient, if appropriate, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host. - peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host. - bgp_delete(): Delete peers before groups, rather than after. And then rather than deleting rsclients, verify that there are none at this point. - bgp_unlock(): Add assertion. - bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself. * lib/command.c,h: Compiler warning fixes. Add cmd_terminate(). Fixed massive leak in install_element() in which cmd_make_descvec() was being called more than once for the same cmd->strvec/string/doc. * lib/log.c: Make closezlog() check fp before calling fclose(). * lib/memory.c: Catch when alloc count goes negative by using signed counts. Correct #endif comment. Add log_memstats_stderr(). * lib/memory.h: Add log_memstats_stderr(). * lib/thread.c: thread->funcname was being accessed in thread_call() after it had been freed. Rearranged things so that thread_call() frees funcname. Also made it so thread_master_free() cleans up cpu_record. * lib/vty.c,h: Use global command_cr. Add vty_terminate(). * lib/zclient.c,h: Re-enable zclient_free().
* [lib] Fix IPv6 normalisationStephen Hemminger2009-07-161-0/+1
| | | | | | * lib/sockunion.c: (sockunion_normalise_mapped) The code to normalize address was not copying port value - probably reason why IPV4 in IPV6 never worked right.
* [lib/cleanup] Use a typedef for the thread typePaul Jakma2009-06-302-6/+8
| | | | | * lib/thread.{c,h}: As per subject. This will avoid head-scratching for next person who adds a thread-type and gets strange breakage.
* Fixes to RFC2385/MD5 BGPChris Caputo2009-06-231-3/+12
| | | | | | | | | * bgpd/bgp_network.c: Fix MD5 listen in IPv4 version of bgp_socket() by adding listen socket to listen_sockets list so that MD5 passwords can get set. * lib/sockopt.c: (sockopt_tcp_signature) Fix bogus "% Error while applying TCP-Sig to session(s)" / "can't set TCP_MD5SIG option" startup error messages by not returning error when there isn't one.
* [configure] Refine CLOCK_MONOTONIC testPaul Jakma2009-06-181-2/+10
| | | | | | | * configure.ac: Check for the actual CLOCK_MONOTONIC symbol, as clock_gettime need not imply that clock type is supported * lib/zebra.h: use the method given in autoconf docs for sys/time.h inclusion
* [cleanup] Allow message tables to be constantStephen Hemminger2009-06-182-2/+2
| | | | | Avoid bugs, and improve cache locality by allowing message lists to be read/only.
* [cleanup] Use const in smux interfaceStephen Hemminger2009-06-182-10/+11
| | | | smux_trap and oid_copy should allow read-only source.
* [lib] Put symbolic backtrace on system logStephen Hemminger2009-06-181-6/+15
| | | | When BGP crashes, sometimes all we get to see is syslog.
* [lib] sockopt_tcp_signature: sin6 requires HAVE_IPV6Stephen Hemminger2009-06-181-0/+2
| | | | | An external user was building on system without IPv6 and it wouldn't work.
* [gcc] Add gcc printf format checksStephen Hemminger2009-06-181-6/+12
|
* [cleanup] Make command nodes staticStephen Hemminger2009-06-126-14/+14
| | | | | The cmd_nodes used to configure vty, can mostly be static so (basic data hiding 101).
* [cleanup] functions taking no args should be declared with void argsStephen Hemminger2009-06-121-1/+1
| | | | | Use Ansi-C prototypes rather than old K&R method of declaring function without arguments
* [cleanup] add const attribute to lib/if.c::if_dumpStephen Hemminger2009-06-121-1/+1

* [cleanup] Convert XMALLOC/memset to XCALLOCStephen Hemminger2009-06-127-33/+9
| | | | Simple conversion of XMALLOC/memset to XCALLOC
* [bgpd] Add support for the old Linux 2.4, TCP_MD5_AUTH RFC2385 patchPaul Jakma2009-06-121-2/+25
| | | | | | | | | * configure.ac: Add a --enable-linux24-tcp-md5 argument, to compile in support for the old TCP-MD5 patch for Linux 2.4 systems. This overrides auto-detection of TCP-MD5 supported by the target system. * lib/sockopt.c: (sockopt_tcp_signature) add in a variant for the old Linux 2.4, TCP_MD5_AUTH variant of TCP-MD5 support, conditional on the previous configure arg.
* [snmp] Compiler warning fixes for when "--enable-snmp" is configured.Chris Caputo2009-06-021-51/+44
| | | | | Compiled on 32-bit and 64-bit linux gcc 4.1.2 platforms. No run-time testing on 32-bit and limited run-time testing on 64-bit.
* [smux] 64-bit fix for lib/smux.h SNMP_INTEGER() macroChris Caputo2009-06-021-2/+2
| | | | | | | | | | | | | | | | | | Macro SNMP_INTEGER() prepares data which is eventually processed by asn_build_int(). SNMP_INTEGER() was using "int32_t" whereas asn_build_int() uses "long". On 32-bit systems these are the same, both 4 bytes, but on x86 64-bit systems "long" is 8 bytes. asn_build_int()'s reaction to an improperly sized value is to return a NULL pointer. Quagga's smux.c would eventually get this NULL pointer and use it in calculations to determine how much data to send over the smux connection, resulting in garbage being sent to the SNMP agent. Corrected SNMP_INTEGER() to use "long". Tested on 32-bit and 64-bit x86 Linux 2.6.27.10 systems running Quagga 0.99.11 with bgpd smux.
* [bgp] Fix crash on SIGHUP, deref of freed workqueuesSteve Hill2009-06-021-0/+3
| | | | | | | * lib/workqueue.c: free-ing workqueues had never been tested obviously, queue's thread was not being stopped * bgpd/bgpd.c: null out freed workqueues, to prevent acting on freed workqueues
* [lib] Fix timer precision.Joakim Tjernlund2008-11-291-1/+1
| | | | | | | | Whenever a thread adds an timer funcname_thread_add_timer_timeval() gets called to add the timer. Before adding the timer a quagga_gettimeofday() call is made to do some time house keeping. However quagga_gettimeofday() only updates recent_time, not relative_time that is used to calculate the alarm_time. Replace with quagga_get_relative (NULL)
* [lib] Move type cast in Fletcher checksumJoakim Tjernlund2008-11-291-1/+1
| | | | | | | | The int type cast should be on the whole expression passed to the mod operator. Otherwise it won't work when/if c0/c1 is unsigned. Making c0/c1 unsigned makes it possible to use 5802 as MODX value.
* [lib] fix missing sockunion_normalise_mappedPaul Jakma2008-11-241-0/+1
| | | | | * lib/sockunion.c: (sockunion_accept) sockunion needs to be normalised here, as it used to before this was moved to a dedicated function..
* [lib] Switch Fletcher checksum back to old ospfd versionPaul Jakma2008-11-162-33/+21
| | | | | | | | | | | | | | | | | | | | | | * lib/checksum.c: (fletcher_checksum) Switch the second phase of the checksum back to the old ospfd logic. The isisd-derived version: a) is very hard to follow b) had some kind of subtle bug that caused it be wrong when c0=0 and c1=254 (potentially fixable by doing the mods before adjusting x and y) Additionally: - explicitely cast expressions using non-internal variables to int, to ensure the result is signed. - defensively change the length argument to 'size_t', to ensure the code works with that argument being unsigned.. Thanks to Joakim Tjernlund for the investigative work into this bug. * tests/test-checksum.c: new file to exercise the checksum code.
* [lib] re-enable conversion of v6mapped INET6 sockunions to regular INETPaul Jakma2008-09-091-40/+20
| | | | | | | | | | * lib/sockunion.c: Re-enable conversion of v6mapped INET6 sockunions to regular INET sockunions, which was disabled in 0df7c9, as it leads to failures in sockunion_cmp. (sockunion_normalise_mapped) consolidate here (sockunion_accept) remove conversion code altogether here - no sockunion is created (sockunion_get{sockname,peername}) normalise newly created sockunion.

| * [vty] Add support for a 'restricted mode' with anonymous vty connectionsPaul Jakma2008-08-234-4/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib/command.h: Add a RESTRICTED_NODE, intended for use with anonymous, 'no login' vtys, to provide a subset of 'view' mode commands. * lib/command.c: Add RESTRICTED_NODE bits, nothing special, just following VIEW_NODE. * lib/vty.c: (vty_auth) enable authentication should fall back to restricted/view node as appropriate. (vty_create) init vty's to restricted/view node as appropriate, for the 'no login' case. (vty_{no_,}restricted_mode_cmd) config commands to enable 'anonymous restricted' in vty configuration. (vty_config_write) 'anonymous restricted' config.
