Weird behavior with writes to a unix socket pair

Hi, I've been testing the effects of the SO_RCVBUF/SO_SNDBUF socket options on unix sockets on various platforms, and I've run into some curious unix socket behavior on Cygwin (independent of the SO_RCVBUF/SO_SNDBUF options). This piece of code should get blocked in one of the writes (and it

malloc(0) crashing with SIGABRT

There's been a twitter discussion on how different POSIX platforms handle malloc(0): https://twitter.com/sortiecat/status/1170697927804817412 . As for Cygwin, the answer appears to be "not well", but this should be easy to fix. Best regards, Petr Skocik -- Problem reports:

bind() behavior inconsistency with Linux and MacOS

Hi. I don't know if this is technically a bug, but I've noticed that unlike on Linux or MacOS, I a cannot bind a unix domain socket in a child process and then listen on it in the parent. The bind succeeds but `listen()` in the parent then fails with EINVAL. (The reason I'd like to `bind` in a

uc_sigmask set in a sigaction signal handler not honored

Hi. Correct me if I'm wrong but POSIX appears to define https://pubs.opengroup.org/onlinepubs/7908799/xsh/ucontext.h.html as, among other things, containing the field: sigset_tuc_sigmask the set of signals that are blocked when this context is active and it also
