    OTP-12445    Application(s): erts

                 Fix getifaddrs realloc pointer error

                 When a buffer was exhausted and subsequently
                 reallocated, we could get an unsafe pointer pointing to
                 faulty memory.

                 For this to occur we would need to have a large number
                 of interfaces and a reallocation of memory to a lower
                 addresses.

                 The symptom would be garbage returned from
                 erlang:port_control(Port, 25, [])
                 (prim_inet:getifaddrs(Port) resulting in a badarg) or a
                 segmentation fault.

                 Don't close all file descriptors twice in child_setup

                 The commit c2b4eab25c907f453a394d382c04cd04e6c06b49
                 introduced an error in which child_setup erroneously
                 tried to close all file descriptors twice.

                 Use closefrom() if available when closing all file
                 descriptors.

                 The function closefrom() was only used in the vfork()
                 case before but is now also used in the fork() case if
                 available.


    OTP-12447    Application(s): erts

                 During a crashdump all file descriptors are closed to
                 ensure the closing of the epmd port and to reserve a
                 file descriptor for the crashdump file.

                 If a driver (third party library) cannot handle closing
                 of sockets this could result in a segmentation fault in
                 which case a crashdump would not be produced. This is
                 now fixed by only closing inets sockets via an
                 emergency close callback to the driver and thus closing
                 the epmd socket.

   The inets-5.10.5 application can be applied independently of other
   applications on a full OTP 17 installation.

                 Related Id(s): seq12786

                 mod_alias now handles https-URIs properly

                 Consistent view of configuration parameter
                 keep_alive_timeout, should be presented in the
                 httpd:info/[1,2] function in the same unit as it is
                 inputted.


   --- Improvements and New Features ---

    OTP-12429    Application(s): inets

                 Gracefully handle invalid content-lenght headers
                 instead of crashing in list_to_integer.
