2022-07-15Merge commit 'c70b3198' into thread-next [lots of conflicts]Maria Matejka
There were more conflicts that I'd like to see, most notably in route export. If a bisect identifies this commit with something related, it may be simply true that this commit introduces that bug. Let's hope it doesn't happen.
2022-05-04Explicit definition structures of route attributesMaria Matejka
Changes in internal API: * Every route attribute must be defined as struct ea_class somewhere. * Registration of route attributes known at startup must be done by ea_register_init() from protocol build functions. * Every attribute has now its symbol registered in a global symbol table defined as SYM_ATTRIBUTE * All attribute ID's are dynamically allocated. * Attribute value custom formatting hook is defined in the ea_class. * Attribute names are the same for display and filters, always prefixed by protocol name. Also added some unit testing code for filters with route attributes.

2021-11-27Memory statistics split into Effective and OverheadMaria Matejka
This feature is intended mostly for checking that BIRD's allocation strategies don't consume much memory space. There are some cases where withdrawing routes in a specific order lead to memory fragmentation and this output should give the user at least a notion of how much memory is actually used for data storage and how much memory is "just allocated" or used for overhead. Also raising the "system allocator overhead estimation" from 8 to 16 bytes; it is probably even more. I've found 16 as a local minimum in best scenarios among reachable machines. I couldn't find any reasonable method to estimate this value when BIRD starts up. This commit also fixes the inaccurate computation of memory overhead for slabs where the "system allocater overhead estimation" was improperly added to the size of mmap-ed memory.

2021-03-30Resources: added mb_move() to complement rmove() for memory blocksMaria Matejka
2021-03-25Slab: head now uses bitmask for used/free nodes info instead of listsMaria Matejka
From now, there are no auxiliary pointers stored in the free slab nodes. This led to strange debugging problems if use-after-free happened in slab-allocated structures, especially if the structure's first member is a next pointer. This also reduces the memory needed by 1 pointer per allocated object. OTOH, we now rely on pages being aligned to their size's multiple, which is quite common anyway.
2020-11-24lib/slab: introduce sl_allocz() function and use it in BabelToke Høiland-Jørgensen
The babel protocol code was initialising objects returned from the slab allocator by assigning to each of the struct members individually, but wasn't touching the NODE member while doing so. This leads to warnings on debug builds since commit: baac7009063d ("List expensive check.") To fix this, introduce an sl_allocz() variant of the slab allocator which will zero out the memory before returning it, and switch all the babel call sites to use this version. The overhead for doing this should be negligible for small objects, and in the case of babel, the largest object being allocated was being zeroed anyway, so we can drop the memset in babel_read_tlv().

2016-12-07RPKI protocol with one cache server per protocolPavel Tvrdík
The RPKI protocol (RFC 6810) using the RTRLib (http://rpki.realmv6.org/) that is integrated inside the BIRD's code. Implemeted transports are: - unprotected transport over TCP - secure transport over SSHv2 Example configuration of bird.conf: ... roa4 table r4; roa6 table r6; protocol rpki { debug all; # Import both IPv4 and IPv6 ROAs roa4 { table r4; }; roa6 { table r6; }; # Set cache server (validator) address, # overwrite default port 323 remote "rpki-validator.realmv6.org" port 8282; # Overwrite default time intervals retry 10; # Default 600 seconds refresh 60; # Default 3600 seconds expire 600; # Default 7200 seconds } protocol rpki { debug all; # Import only IPv4 routes roa4 { table r4; }; # Set cache server address to localhost, # use default ports tcp => 323 or ssh => 22 remote 127.0.0.1; # Use SSH transport instead of unprotected transport over TCP ssh encryption { bird private key "/home/birdgeek/.ssh/id_rsa"; remote public key "/home/birdgeek/.ssh/known_hosts"; user "birdgeek"; }; } ...

2004-05-31Added rmove() (by Andreas, tweaked by me).Martin Mares
2000-05-08Implemented debugging function rlookup() which you can call from gdbMartin Mares
to see what resource does the address given as a parameter belong to.
2000-03-29Avoid conflicts with libraries defining their own xmalloc by definingMartin Mares
xmalloc to bird_xmalloc internally.
1999-03-29Added lp_flush() which flushes contents of a linear pool, leaving all theMartin Mares
memory available for subsequent allocations from the same pool. Both flushing and re-using the memory costs just few instructions.
1999-03-04Use dmalloc instead of EFence when available (dmalloc has lot of improvementsMartin Mares
over EFence and also hopefully smaller memory overhead, but sadly it's non-free for commercial use). If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable' checks by default. Also introduced mb_allocz() for cleared mb_alloc().
1998-12-06Name cleanups as suggested by Pavel:Martin Mares
- cfg_strcpy() -> cfg_strdup() - mempool -> linpool, mp_* -> lp_* [to avoid confusion with memblock, mb_*] Anyway, it might be better to stop ranting about names and do some *real* work.
