In qemu-linux-user, when calling gethostbyname2(), it was hanging in .__res_nmkquery. (gdb) bt 0 in .__res_nmkquery () from /lib64/libresolv.so.2 1 in .__libc_res_nquery () from /lib64/libresolv.so.2 2 in .__libc_res_nsearch () from /lib64/libresolv.so.2 3 in ._nss_dns_gethostbyname3_r () from /lib64/libnss_dns.so.2 4 in ._nss_dns_gethostbyname2_r () from /lib64/libnss_dns.so.2 5 in .gethostbyname2_r () from /lib64/libc.so.6 6 in .gethostbyname2 () from /lib64/libc.so.6 .__res_nmkquery() is: ... do { RANDOM_BITS (randombits); } while ((randombits & 0xffff) == 0); ... <.__res_nmkquery+112>: mftbl r11 <.__res_nmkquery+116>: clrlwi r10,r11,16 <.__res_nmkquery+120>: cmpwi cr7,r10,0 <.__res_nmkquery+124>: beq cr7,<.__res_nmkquery+112> but as mftbl (Move From Time Base Lower) is not implemented, r11 is always 0, so we have an infinite loop. This patch fills the Time Base register with cpu_get_real_ticks(). Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Alexander Graf <agraf@suse.de> |
