Hey there,

recently I debugged my application that uses the SCTP_NKE library. Resuming the application after halt at a breakpoint, the system crashed. After it rebooted, I read the error report and especially the error message:

assertion failed: (sb->sb_flags & SB_LOCK) || (so->so_state & SS_DEFUNCT) || (so->so_flags1 & SOF1_DEFUNCTINPROG), file: /BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-4570.71.3/bsd/kern/uipc_socket2.c

Now because of the assertion is related to sockets and since the process that uses the SCTP library provoked the crash (darias_xtask), I thought that this has maybe something to do with the SCTP library. I also tried provoking the system crash by redoing the debugging steps - but without luck. So my guess is that it either has nothing to do with the SCTP library after all or the error only occurs in very specific scenarios. Nevertheless, I thought I'd share this with you (and especially the full error report) so that you can have a look at it if you want to.

Feel free to close this issue if - with the information provided - it is not clear that the problem arises from the SCTP library. If I find a way to repeatedly provoke the system crash I'll let you now.

Best,
Pascal

Hey there,

I tried building the repository using Xcode and received the following error:
No member named 'socket' in 'struct xsctp_inb'

The error is provoked by lines 519-521 in sctp_sysctl.c:
#if !(defined(FreeBSD) && (__FreeBSD_version < 1001517))
xinpcb.socket = (uintptr_t)inp->sctp_socket;
#endif

Since I'm building Mac OS and not on FreeBSD I guess it is correct that this code snippet gets 'included' by the precompiler right?

Best and thanks in advance,
Pascal

Hello,

after updating my OS to Mojave I was wondering if a SCTP_NKE Version for Mojave is currently planned. If not, are there any information what would need to be changed in the HighSierra Version to make it work with Mojave? I am everything else than an expert in Xcode or OS X kernel extensions but if the changes are restricted to changing some version flags I'm sure that I could make it work myself.

Best

after installing SCTP_NKE on MacOS 10.13 I was trying to import <netinet/sctp.h> and after hours of trying to understand why it wouldn't compile I finally figured out that Xcode pulls its libraries from a different location then the systems. if you go into Xcode by right-clicking and showing contents or by going to "/Applications/Xcode.app/Contents/Developer/usr" you can see the files it uses to compile. after adding socket.h to xcode's "/usr/include/sys/" and sctp.h to xcode's "/usr/include/netinet/" and sctp_uio.h to xcode's "/usr/include/netinet/" and libsctp.dylib to xcodes "/usr/lib/" then going into xcode and adding the library to the linked library it was able to compile my project using <netinet/sctp.h> hopes this helps anyone having the same issue as i have had

Hi,

it seems the SCTP_NKE_HighSierra_02.dmg (https://github.com/sctplab/SCTP_NKE_HighSierra/releases/download/v01/SCTP_NKE_HighSierra_02.dmg) is not available anymore for download. Trying to download will result in a 404 not found.

Another question on this: Would this sctp stack also work fpr MacOS 10.15.* Catalina?

Thanks in advance!

Is it possible to update the NKE for the newest versions of macos (Ventura, Sonoma)?
Or maybe help with some instructions on how to build them myself?
