Full_Name: Asif Iqbal Desai Version: 2.4.16 OS: Solaris 10 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (130.214.64.6) This is a consulation bug for clarification on close() being called from ldap_unbind_s with fd = 1. The application uses ldap client apis for user authentication. We recently upgraded to use OpenLDAP version 2.4.16 and are getting an unexpected AIO error issue when ldap user authentication is enabled. Investigating further revealed that from ldap_unbind_s ( close(-1) is getting called. However the close function of solaris libaio does a special handling when fd < 0 which causes AIO errors. The application needs solaris aio support and hence cannot link libc before libaio. Is there any specific reason for close being called with fd = -1 from ldap_unbind_s. This issue didnot exist with OpenLDAP 2.3.27. Following is the stacktrace: [1] _libaio_close(0xffffffffffffffff, 0x2, 0x1, 0xffffffff7f300200, 0x0, 0x0), at 0xffffffff7f406a64 [2] sb_stream_close(0x100151d80, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), at 0xffffffff7d21eafc [3] ber_int_sb_close(0x100151d00, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), at 0xffffffff7d21e160 [4] ber_sockbuf_free(0x100151d00, 0x1001497d0, 0x1, 0x1, 0xffffffff7dbad2ec, 0xd), at 0xffffffff7d21cebc [5] ldap_ld_free(0x100149520, 0x1, 0x0, 0x0, 0x100117020, 0xdc3), at 0xffffffff7d26a4bc [6] ldap_unbind_ext(0x100149520, 0x0, 0x0, 0x1001219e0, 0x1001219f8, 0x100121a00), at 0xffffffff7d26a048 [7] ldap_unbind_s(0x100149520, 0x1001471d0, 0x100149520, 0xfffffffffffffff2, 0x0, 0x100117728), at 0xffffffff7d26a55c ... ... Thanks in Advance, Asif Iqbal Desai
Can somebody take a look at this issue. Note that the issue here is with close() being called from ldap_unbind_s with fd = (-1). Please read the first line in my original bug description email as: This is a consulation bug for clarification on close() being called from ldap_unbind_s with fd = -1.

I've checked 2.3.43 and 2.4.23; in both cases ber_int_sb_close() is being called twice on the same sockbuf. I suppose that might be considered a bug, but certainly the behavior has not changed between 2.3 and 2.4. > Following is the stacktrace: > [1] _libaio_close(0xffffffffffffffff, 0x2, 0x1, 0xffffffff7f300200, 0x0, 0x0), > at 0xffffffff7f406a64 > [2] sb_stream_close(0x100151d80, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), at > 0xffffffff7d21eafc > [3] ber_int_sb_close(0x100151d00, 0x0, 0x0, 0xffffffff7f300200, 0x0, 0x0), at > 0xffffffff7d21e160 > [4] ber_sockbuf_free(0x100151d00, 0x1001497d0, 0x1, 0x1, 0xffffffff7dbad2ec, > 0xd), at 0xffffffff7d21cebc > [5] ldap_ld_free(0x100149520, 0x1, 0x0, 0x0, 0x100117020, 0xdc3), at > 0xffffffff7d26a4bc > [6] ldap_unbind_ext(0x100149520, 0x0, 0x0, 0x1001219e0, 0x1001219f8, > 0x100121a00), at 0xffffffff7d26a048 > [7] ldap_unbind_s(0x100149520, 0x1001471d0, 0x100149520, 0xfffffffffffffff2, > 0x0, 0x100117728), at 0xffffffff7d26a55c > ... > ... > > Thanks in Advance, > Asif Iqbal Desai > > -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
