Igor Sysoev 6b9882fc14 Fixed segmentation fault during reconfiguration. 
If idle connection was closed before h1proto had been allocated
then c->socket.data is NULL.  This happens if nxt_h1p_idle_response()
is called by nxt_h1p_idle_close().  However, h1p->conn_write_tail
is used only in nxt_h1p_request_send() that would not be called
after nxt_h1p_idle_response().

The bug was introduced in f237e8c553fd.

Igor Sysoev 09f4db1fc0 Fixed use-after-free error during reconfiguration. 
An idle connection was not removed from idle connection list
if the connections detected that listening socket had been closed.

Igor Sysoev 22c88f0253 Upstream connection was not closed for short chunked response. 2020-09-07 15:21:14 +03:00
Igor Sysoev 18fbfc3d50 Destroying temporary router configuration. 
The lifespan of a listening socket is longer than both router
configuration's and temporary router configuration's lifespan,
so the sockets should be stored in persistent queues. Safety
is ensured by the fact that the router processes only one new
configuration at any time.

Igor Sysoev 2d0dca5243 The kqueue EOF flag might be ignored on some conditions. 
If kqueue reported both the EVFILT_READ and the EVFILT_WRITE events
for the socket but only the former had the EV_EOF flag set, the flag
was silently ignored.

Igor Sysoev 96cd6558ce Fixed connect(2) errors processing on old Linuxes. 
While connect(2) states that non-blocking connect should use EPOLLOUT:

  EINPROGRESS
    The socket is non-blocking and the connection cannot be completed
    immediately.  It is possible to select(2) or poll(2) for completion by
    selecting the socket for writing.  After select(2) indicates writability,
    use getsockopt(2) to read the SO_ERROR option at level SOL_SOCKET to
    determine whether connect() completed successfully (SO_ERROR is zero)
    or unsuccessfully (SO_ERROR is one of the usual error codes listed here,
    explaining the reason for the failure).

On connect error, Linux 2.6.32 (CentOS 6) may return EPOLLRDHUP, EPOLLERR,
EPOLLHUP, EPOLLIN, but not EPOLLOUT.
 2019-11-14 16:39:48 +03:00
Igor Sysoev 09e7357b08 Style fixes. 2019-10-10 19:42:41 +03:00

Igor Sysoev 86d4a0e473 Fixed TLS connections hanging. 
After event is delivered from the kernel its further processing is blocked.
Non-ready TSL I/O operation should mark connection I/O state as not ready
to unblock events and to allow their further processing. Otherwise
the connection hangs.
 2019-03-01 18:20:05 +03:00
Igor Sysoev 834e8ca576 Fixed timer and event race condition. 
When idle timeout occurs at the same time as a request comes in,
the timer handler closes connection while the read event triggers
request processing, and this eventually leads to segmentation fault.

Igor Sysoev 50dd54877d Improved epoll failures handling. 
epoll changes are committed to the kernel before epoll_wait() or
on changes array overflow.  In the latter case if there are errors
epoll_wait() timeout was not set to zero.
