* lib: add extern "C" {} blocks to all libfrr headersRenato Westphal2019-02-121-0/+8
| | | | | | | These are necessary to use functions defined in these headers from C++. Signed-off-by: David Lamparter <equinox@diac24.net> Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
* lib: make atomic ops C++ compatibleDavid Lamparter2019-02-111-5/+5
| | | | | | | C++ doesn't have ISO C11 stdatomic.h or "_Atomic inttype", so use std::atomic instead to get the headers compatible. Signed-off-by: David Lamparter <equinox@diac24.net>
* lib: MTYPE_PREFIX_FLOWSPEC should not be exposed by memory.hDonald Sharp2019-02-071-1/+0
| | | | | | This MTYPE should be owned by prefix.c as a STATIC for the file. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* lib: count total memory allocation per MTYPEDavid Lamparter2018-08-081-0/+8
| | | | | | | | If malloc_usable_size() or malloc_size() are available, we can count total usage of a particular MTYPE. (Without the functions, we don't know how much to subtract on free.) Signed-off-by: David Lamparter <equinox@diac24.net>
* lib: prefix support for flowspecPhilippe Guibert2018-03-301-0/+1
| | | | | | | | | | | prefix structure is used to handle flowspec prefixes. A new AFI is introduced: AF_FLOWSPEC. A sub structure named flowspec_prefix is used in prefix to host the flowspec entry. Reason to introduce that new kind is that prefixlen from prefix structure is too short to all the flowspec needs, since NLRI can go over 0xff bytes.

* lib: split off compiler magic into its own fileDavid Lamparter2017-08-241-35/+1

* lib: centralized memstats-at-exitDavid Lamparter2017-08-241-1/+3
| | | | | | | | | adds a new all-daemon "debug memstats-at-exit" command. Also saves memstats to a file in /tmp, useful if a long-running daemon is having weird issues (e.g. in a user install). Fixes: #437 Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

* lib: Linux indentation on memory.[ch]David Lamparter2017-03-311-22/+20
| | | | | | | | | | The fact that I originally wrote this in Linux Kernel style and then reindented it to GNU makes me want to gouge my eyes out every time I look at it. Restore original indentation. [This patch is whitespace-only.] Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: memtypes: restore atomicityDavid Lamparter2017-03-311-2/+3
| | | | | | | the original version of this code already used _Atomic and atomic_*(). Restore this functionality for future multithreading. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: replace MIT license with ISCDavid Lamparter2016-12-011-16/+10
| | | | | | | | Since other parts (e.g. ldpd) use the ISC license, and the ISC license is just a simplified form of the MIT license, just move things over and reduce the number of different licenses we have in use here. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: deregister memtypes on exit/unloadDavid Lamparter2016-09-191-6/+25
| | | | | | | | | | This is useful for DSO modules in order to get support for unloading them dynamically. It also runs on exit, which doesn't matter much. At some future point, the code could be extended to check that allocation counts are 0 on unloading a module. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: clean/restore memory debugging functionsDavid Lamparter2016-09-191-0/+1
| | | | | | | | | | | | This adapts the dump-at-exit handler and removes the old leftover code. (Note the text in log_memtype_stderr was actually incorrect as the only caller in bgpd cleans up configuration before calling it, i.e. any remaining allocations are missing-cleanup bugs.)

* *: split & distribute memtypes and stop (re|ab)using lib/ MTYPEsDavid Lamparter2016-09-191-2/+3
| | | | | | | | | | | | | | | | | | | This is a rather large mechanical commit that splits up the memory types defined in lib/memtypes.c and distributes them into *_memory.[ch] files in the individual daemons. The zebra change is slightly annoying because there is no nice place to put the #include "zebra_memory.h" statement. bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the library for its own use. This is bad practice and would break when the memtype are made static.

* lib: add new extensible memory-type handlingDavid Lamparter2016-09-191-1/+178
| | | | | | | | | | | | This rewrites Quagga's memory per-type allocation counting, without using a fixed global list of types. Instead, source files can declare memory types which get handled through constructor functions called by the dynamic linker during startup.

* lib/memory: fix indirect static link with zlibBaruch Siach2016-09-021-2/+2
| | | | | | | | | | | | | | | | | | quagga SNMP support depends on netsnmp, that optionally depends on OpenSSL, which in turn requires zlib. zlib exports the 'zcalloc' symbol, which collides with a function of the same name in memory.c. This is not a problem when linking dynamically, since quagga does not use zlib directly. But static linking fails with the error: CCLD ospfd .../output/host/usr/mips64el-buildroot-linux-uclibc/sysroot/usr/lib/libz.a(zutil.o): In function `zcalloc': zutil.c:(.text+0x48): multiple definition of `zcalloc' .../output/build/quagga-1.0.20160315/lib/.libs/libzebra.a(memory.o):memory.c:(.text+0x1a0): first defined here Rename 'zcalloc' to 'zzcalloc' to avoid symbol collision.

| | | | | | | | | | * lib/memory.h * mtype_zcalloc(): correct function prototype * XFREE(): make both definitions consistent in setting the pointer to NULL after freeing the memory These changes will only have an effect if MEMORY_LOG is defined (it is not by default).
* [bgpd] Stability fixes including bugs 397, 492Chris Caputo2009-07-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | | | | | | | | * (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h
