[PATCH v3 0/3] MR5195: ws2_32: Implement TCP_KEEPALIVE, TCP_KEEPCNT and TCP_KEEPINTVL socket options
Application "ZusiDisplay" wants to set these socket options. setsockopt() currently returns an error on wine, which prevents the application from working correctly. I'm not really sure if I'm using the IOCTL_AFD_WINE_SET/GET_* correctly. Maybe the new ones should have different "function" numbers and be sorted below the one for TCP_NODELAY? Also, not sure if anything needs to be done in unix/socket.c for portability. Are these TCP_KEEPIDLE etc. constants defined on all OSes supported by wine? If not, how should I handle this? ZusiDisplay seems to work fine if the setsockopt() call is ignored in wine, without returning an error. So if this merge request is not that great, I'd be happy to send a merge request to ignore the call instead. -- v3: ws2_32: Implement TCP_KEEP{ALIVE,CNT,INTVL} options. ws2_32/tests: Test TCP_KEEP{ALIVE,CNT,INTVL} options. include: Add TCP_KEEPCNT and TCP_KEEPINTVL definitions. https://gitlab.winehq.org/wine/wine/-/merge_requests/5195

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=143600 Your paranoid android. === w1064_2qxl (64 bit report) === ws2_32: sock.c:6294: Test failed: failed to wait for thread termination: 0

A brief search suggests that Solaris, FreeBSD, and NetBSD all have them. Mac has them as well, but it calls it TCP_KEEPALIVE like Windows, not TCP_KEEPIDLE, so we should check for that. If we do break compilation anywhere, I suspect it's fine to wait for a report and fix it after the fact. I added some #ifs to hopefully make it work on Mac. I have no way to test it though, and the Mac CI runner is currently offline. So let's see. :-)

We've had problems in the past with applications being very picky about how we do parameter validation, so I'd like to be proactive about getting that right, or at least not copy it from elsewhere without testing. The relevant tests are a bit tricky to read, so I've taken the liberty of adding them and adjusting the implementation appropriately; would you mind fixing up your patches accordingly? [scratch.diff](/uploads/ecf33271bf2f18bce38f7ef6daf40aa7/scratch.diff) Thanks a lot, that's pretty useful! I had to add a new member to the test definition struct for old windows (and initially the wine todo), I hope that's okay. If you'd prefer a different approach, just let me know.
