--- Comment #5 from happy mu <[email protected]> --- hi Quanah yes, there is an issue in ldap DNS search. currently we use *result=gethostbyname_r in function ldap_pvt_gethostbyname_a. but gethostbyname_r is not support 'ipv6' and deprecated , should use getaddrinfo() instead. will openldap fix this issue ? if yes, which version can be use. /*********************************************************************/ ref : http://refspecs.linux-foundation.org/LSB_4.0.0/LSB-Core-generic/LSB-Core-generic/baselib-gethostbyname-r-3.html pstack : 1412 #0 0x00007f5e92426c3d in poll () from /lib64/libc.so.6 1413 #1 0x00007f5e8ffa4f62 in __res_context_send () from /lib64/libresolv.so.2 1414 #2 0x00007f5e8ffa2394 in __res_context_query () from /lib64/libresolv.so.2 1415 #3 0x00007f5e8ffa35ca in __res_context_search () from /lib64/libresolv.so.2 1416 #4 0x00007f5e80a13208 in gethostbyname3_context () from /lib64/libnss_dns.so.2 1417 #5 0x00007f5e80a13cdb in _nss_dns_gethostbyname_r () from /lib64/libnss_dns.so.2 1418 #6 0x00007f5e9244ce6f in gethostbyname_r@@GLIBC_2.2.5 () from /lib64/libc.so.6 1419 #7 0x00007f5e90e2667e in ldap_pvt_gethostbyname_a (name=name@entry=0x7fff152052c0 "mix-udmee-1-67784ddf44-5krt4", resbuf=resbuf@entry=0x7ff f152052a0, buf=buf@entry=0x7fff15205290, result=result@entry=0x7fff15205298, herrno_ptr=herrno_ptr@entry=0x7fff1520528c) at util-int.c:453 1420 #8 0x00007f5e90e268cd in ldap_pvt_get_fqdn (name=0x7fff152052c0 "mix-udmee-1-67784ddf44-5krt4", name@entry=0x0) at util-int.c:851 1421 #9 0x00007f5e90e24afb in ldap_int_initialize (gopts=gopts@entry=0x7f5e91049120 <ldap_int_global_options>, dbglvl=dbglvl@entry=0x7fff1520549 0) at init.c:682 1422 #10 0x00007f5e90e25841 in ldap_set_option (ld=0x0, option=20481, invalue=0x7fff15205490) at options.c:463 Thanks & Regard Happy -----Original Message----- From: [email protected] <[email protected]> Sent: 2020年7月14日 23:44 To: Mu, Happy (NSB - CN/Qingdao) <[email protected]> Subject: [Issue 9287] ldap_create cause 10s delay in some scenario https://bugs.openldap.org/show_bug.cgi?id=9287 Quanah Gibson-Mount <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |FEEDBACK -- You are receiving this mail because: You are on the CC list for the issue.
