* datapath-windows: Alg support for ftp and tftp in conntrackldejing2022-09-201-0/+1
| | | | | | | | | | | | | | | | | | | | | This patch mainly support alg field in ct action when process ftp/tftp traffic. Tftp with alg mainly parse the tftp packet (IPv4/IPv6), extract connect info from the tftp packet and create the related connection. For ftp, previous version has supported process of ftp traffic. However, previous version regard traffic from or to port 21 as ftp traffic, this is incorrect in some scenario. This version adds alg field in ct for ftp traffic, we could use ct(alg=ftp) to process any ftp traffic from/to any port. IPv4/IPv6. Test cases: 1) ftp ipv4/ipv6 use alg field in the normal and nat scenario. 2) tftp ipv4/ipv6 use alg field in the normal and nat scenario.

* include/windows/unistd.h: Fixed type cast warning on Windows.Sergey Madaminov2021-09-161-1/+1
| | | | | | | | | | | | | | | | | | | | Currently, the function call type cast for getting file handle produces a warning during OvS compilation on Windows with the following message: ..\include\windows\unistd.h:97:25: warning: cast from function call of type 'intptr_t' (aka 'int') to non-matching type 'HANDLE' (aka 'void *') [-Wbad-function-cast] HANDLE h = (HANDLE) _get_osfhandle(fd); There is a function `LongToHandle()` to perform such cast [1]. But as `intptr_t` can be either `long long` for 64-bit or `int` for 32-bit, instead of clogging the code with `#ifdef` macros to use different cast functions, we can perform this cast directly.

* ct-dpif, dpif-netlink: Add conntrack timeout policy supportYi-Hung Wei2019-09-262-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch first defines the dpif interface for a datapath to support adding, deleting, getting and dumping conntrack timeout policy. The timeout policy is identified by a 4 bytes unsigned integer in datapath, and it currently support timeout for TCP, UDP, and ICMP protocols. Moreover, this patch provides the implementation for Linux kernel datapath in dpif-netlink. In Linux kernel, the timeout policy is maintained per L3/L4 protocol, and it is identified by 32 bytes null terminated string. On the other hand, in vswitchd, the timeout policy is a generic one that consists of all the supported L4 protocols. Therefore, one of the main task in dpif-netlink is to break down the generic timeout policy into 6 sub policies (ipv4 tcp, udp, icmp, and ipv6 tcp, udp, icmp), and push down the configuration using the netlink API in netlink-conntrack.c. This patch also adds missing symbols in the windows datapath so that the build on windows can pass.

* Fix nonstandard isatty on WindowsAlin Serdean2017-07-061-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of tests are failing, due to the open flow ports being outputted using names instead of numbers. i.e.: http://64.119.130.115/ovs/beb75a40fdc295bfd6521b0068b4cd12f6de507c/testsuite.dir/0464/testsuite.log.gz The issues encountered above is because 'monitor' with 'detach' arguments are specified, that in turn will call 'close_standard_fds' (https://github.com/openvswitch/ovs/blob/master/lib/daemon-unix.c#L472) which will create a duplicate fd over '/dev/null' on Linux and 'nul' on Windows. 'isatty' will be called on those FDs. What POSIX standard says: http://pubs.opengroup.org/onlinepubs/009695399/functions/isatty.html 'The isatty() function shall test whether fildes, an open file descriptor, is associated with a terminal device.' What MSDN says: https://msdn.microsoft.com/en-us/library/f4s0ddew(VS.80).aspx 'The _isatty function determines whether fd is associated with a character device (a terminal, console, printer, or serial port).' This patch adds another check using 'GetConsoleMode' https://msdn.microsoft.com/en-us/library/windows/desktop/ms683167(v=vs.85).aspx which will fail if the handle pointing to the file descriptor is not associated to a console.

* windows: add definition of getpid and getcwdAlin Serdean2017-05-251-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | getcwd - is used in lib/util.c. getcwd is deprecated on Windows but has _getcwd which is defined in <direct.h>: https://msdn.microsoft.com/en-us/library/sf98bd4y(v=vs.120).aspx getpid - is used in several files (i.e. lib/vlog.c). getpid is also and deprecated and _getpid should be used: https://msdn.microsoft.com/en-us/library/t2y34y40(v=vs.120).aspx The problem using _getpid is that the definition is in <process.h>. A file called process.h also exists in the lib folder. This will mess up includes. An option would be to use a wrapper like we use for lib/string.h(.in) but that would mean to also add it to the automake chain. A simple solution would be to map it to GetCurrentProcessId https://msdn.microsoft.com/en-us/library/windows/desktop/ms683180(v=vs.85).aspx _getpid uses GetCurrentProcessId behind the scenes, casting the result is not required.

* vlog: Ability to override the default log facility.Gurucharan Shetty2015-01-281-0/+13
| | | | | | | | | | | | | | | When Open vSwitch is run in hundreds of hypervisors, it is useful to collect log messages through log collectors. To collect log messages like this, it is useful to log them in a particular RFC5424 facility in the local system. The log collectors can then be used to collect logs anytime desired. This commit provides a sysadmin the ability to specify the facility through which the log messages are logged.
