-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys! A new version of BIRD is close to be released. However there were a lot of changes mainly in OSPF code. Therefore we would like to ask you for some testing before the final version. So if you want to help us, please download here: ftp://bird.network.cz/pub/bird/testing/bird-1.5.0pre.tar.gz And let us know if if you were able to test it. Both positive and negative feedback is very welcome.

Problem running/compiling bird for ARM

Hi, I did a bit of research on the error. I have added the following lines to dbdes.c in ospf_dbdes_receive function -— SNIP -- unsigned int size = ntohs(ps_i->length); /* log sizes */ log(L_ERR "OSPF DBDES packet is (%u B)", n->ip, size); log(L_ERR "OSPF DBDES packet should be (%u B)", sizeof(struct ospf_dbdes_packet)); log(L_ERR "OSPF packet should be (%u B)", sizeof(struct ospf_packet)); log(L_ERR "IMMS should be (%u B)", sizeof(union imms)); log(L_ERR "Size of u8 %u", sizeof(u8)); log(L_ERR "Size of u16 %u", sizeof(u16)); log(L_ERR "Size of u32 %u", sizeof(u32)); log(L_ERR "Size of u64 %u", sizeof(u64)); log(L_ERR "Size of char %u", sizeof(char)); log(L_ERR "Size of short int %u", sizeof(short int)); log(L_ERR "Size of int %u", sizeof(int)); log(L_ERR "Size of long int %u", sizeof(long int)); log(L_ERR "Size of long long int %u", sizeof(long long int)); -— SNIP — This is the result on my 32-bit ARM router: Nov 2 21:38:35 router-2 daemon.err bird6: OSPF DBDES packet is (28 B) Nov 2 21:38:35 router-2 daemon.err bird6: OSPF DBDES packet should be (32 B) Nov 2 21:38:35 router-2 daemon.err bird6: OSPF packet should be (16 B) Nov 2 21:38:35 router-2 daemon.err bird6: IMMS should be (4 B) Nov 2 21:38:35 router-2 daemon.err bird6: Size of u8 1 Nov 2 21:38:35 router-2 daemon.err bird6: Size of u16 2 Nov 2 21:38:35 router-2 daemon.err bird6: Size of u32 4 Nov 2 21:38:35 router-2 daemon.err bird6: Size of u64 8 Nov 2 21:38:35 router-2 daemon.err bird6: Size of char 1 Nov 2 21:38:35 router-2 daemon.err bird6: Size of short int 2 Nov 2 21:38:35 router-2 daemon.err bird6: Size of int 4 Nov 2 21:38:35 router-2 daemon.err bird6: Size of long int 4 Nov 2 21:38:35 router-2 daemon.err bird6: Size of long long int 8 This is the result on 64-bit ubuntu 14.04 machine: 2014-11-02 22:57:14 <ERR> OSPF DBDES packet is (4269801472 B) 2014-11-02 22:57:14 <ERR> OSPF DBDES packet should be (28 B) 2014-11-02 22:57:14 <ERR> OSPF packet should be (16 B) 2014-11-02 22:57:14 <ERR> IMMS should be (1 B) 2014-11-02 22:57:14 <ERR> Size of u8 1 2014-11-02 22:57:14 <ERR> Size of u16 2 2014-11-02 22:57:14 <ERR> Size of u32 4 2014-11-02 22:57:14 <ERR> Size of u64 8 2014-11-02 22:57:14 <ERR> Size of char 1 2014-11-02 22:57:14 <ERR> Size of short int 2 2014-11-02 22:57:14 <ERR> Size of int 4 2014-11-02 22:57:14 <ERR> Size of long int 8 2014-11-02 22:57:14 <ERR> Size of long long int 8 I think that for some reason the ARM gcc () interprets this struct struct immsb { #ifdef CPU_BIG_ENDIAN u8 padding:5; u8 i:1; u8 m:1; u8 ms:1; #else u8 ms:1; u8 m:1; u8 i:1; u8 padding:5; #endif }; as 4 byte struct, instead of 1 byte subdivided into bit-long parts.
