Maximilian Immanuel Brandtner dbd7fa2c83 tls: don't abort the connection on signal-interrupted sends 
[ Upstream commit af0e5cdd03 ]

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.

Fixes: b341ca51d2 ("tls: Fix tls_sw_sendmsg error handling")
