[Issue 9947] New: Race in epoch.c

https://bugs.openldap.org/show_bug.cgi?id=9947 Issue ID: 9947 Summary: Race in epoch.c Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: lloadd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- When epoch_leave() tests whether other threads might still be alive, it can test things in reverse order, testing too early to catch a thread to come in and too late to see a thread that just left. If those two saw each other, the clock would not advance and the data in refs might actually still be a reachable pointer. The tests in epoch_leave can actually be simplified leading to machine code not all compilers could figure out by themselves. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9925] New: Fix some compilation issues around usage of #if and #ifdef

https://bugs.openldap.org/show_bug.cgi?id=9925 Issue ID: 9925 Summary: Fix some compilation issues around usage of #if and #ifdef Product: OpenLDAP Version: unspecified Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: connor.smith(a)hitachivantara.com Target Milestone: --- Created attachment 918 --> https://bugs.openldap.org/attachment.cgi?id=918&action=edit git format-patch I noticed a few issues while working with OpenLDAP that would lead to compiler warnings and the like in our particular build environment. They're quite minor, but it would still be good to have them patched upstream. In include/ac/socket.h: Use #elif defined(...) for HAVE_WINSOCK and MACOS. All other instances of these macros use #ifdef or similar. A compiler may warn about them not being defined. In libraries/liblber/sockbuf.c, (DOS && PCNFS) and (DOS && NCSA) were replaced with HAVE_PCNFS and HAVE_NCSA, respectively. It seems logical to do the same at the only remaining occurrence of DOS, PCNFS, and NCSA. For context on the latter: the actual warning was about #elif DOS, similar to #elif HAVE_WINSOCK and #elif MACOS, but looking into it it seemed to make sense to bring socket.h in line with sockbuf.c. In libraries/liblunicode/ucdata/ucgendat.c: Use #if HARDCODE_DATA consistently, replacing two instances of #ifdef. HARDCODE_DATA is always defined, and this way you can set HARDCODE_DATA to 0 and have it work, rather than it going down the wrong branch and failing in these two cases.

I am not a daily C hacker, but I guess cb_data needs to be typed to "unsigned char" just like data from sasl_channel_binding_t (https://github.com/cyrusimap/cyrus-sasl/blob/cb549ef71c5bb646fe583697ebdcab…). Or at least a malloc with an "unsigned char", save the pointer start address, copy the prefix, increment by prefix length, copy the channel binding value and then assign the pointer start address to the output struct. I will unset SASL_CHANNEL_BINDING for now since it is not required in your AD environment when SASL GSSAPI with minssf=1 is set. -- You are receiving this mail because: You are on the CC list for the issue.
