If anyone has any objections, please let me know. ------------------ From: Maximilian Immanuel Brandtner [ Upstream commit af0e5cdd031f4f4a8f6d4160bfbda4f36872b0ed ] When a signal interrupts a blocking send, tls_tx_records() treats the resulting -ERESTARTSYS as a transmission failure and marks the socket errored via tls_err_abort() with the raw error code. Later syscalls return the kernel-internal errno 512 (ERESTARTSYS) to userspace, as the signal it stems from is no longer pending during syscall exit and thus never translated. An interrupted send is not a connection error: the partially sent record stays queued and is resent later. Interrupt error codes are therefore excluded from the abort in the same way as -EAGAIN.
