Sorry about this, I meant to send this patch to the *buildroot* list to fix the bugs in the current version of lttng that's part of buildroot. It's non-obviously but significantly broken on 32-bit ARM systems and I wanted to get it fixed before the next version of lttng-modules is released. Not sure how I got the address incorrect. > > Patch to fix recv() syscall missing in ARM syscall list. > > This was probably missing because the current ARM syscall instrumentation > was generated from a 3.4.25 kernel that was missing SYSCALL macro > description of those system calls.

My most recent available ARM system uses 3.18.0, if a patch for that kernel is desirable, I'll submit one. But it sounded like a newer 4.x kernel was wanted and I don't have such a system. This was meant to be sent to buildroot as a bug fix until a proper fix was came from upstream lttng. Usually when a distro does patching to fix some cross-build issue or something like that, one prefers to fix on the side of "minimal changes" instead of "best fix". Less trouble porting that way. That's why I didn't add 3.18 and made the smaller patch to fix the 3.4.25 descriptions. > > Patch from lttng mailing list that fixes kernel timestamps being off > > by about ~2 seconds on 32-bit systems.

I didn't know there was a new version, as I didn't see a followup on the thread about the original. I'll send the newer patch from stable-2.9 to buildroot instead of this one then. Apologies again for sending this to the wrong list. _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
