- get socket name SYNOPSIS top #include
Error 22 Invalid Argument Zip
the buffer pointed to by addr. The addrlen argument should be initialized to indicate the amount of space (in bytes)
Mount Error 22 Invalid Argument
pointed to by addr. On return it contains the actual size of the socket address. The returned address is truncated if the buffer provided is too small; in this case, addrlen

will return a value greater than was supplied to the call. RETURN VALUE top On success, zero is returned. On error, -1 is returned, and errno is set appropriately. ERRORS top EBADF The argument sockfd is not a valid file descriptor. EFAULT The addr argument points to memory not in a valid part of the process svr4 error 22 invalid argument address space. EINVAL addrlen is invalid (e.g., is negative). ENOBUFS Insufficient resources were available in the system to perform the operation. ENOTSOCK The file descriptor sockfd does not refer to a socket. CONFORMING TO top POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD (getsockname() first appeared in 4.2BSD). NOTES top The third argument of getsockname() is in reality an int * (and this is what 4.x BSD and libc4 and libc5 have). Some POSIX confusion resulted in the present socklen_t, also used by glibc.

According to several 10 Gig of logfiles the error occurs in all kind of situations be it POST or GET and getsockname example always with the same traceback. What I also see is that errors are more frequent when loads are higher, which leads me to the conclusion that this might be a resource dependency specially the fd count per process which http://man7.org/linux/man-pages/man2/getsockname.2.html we currently have at 8192 as I already suspected in our previous discussion end of April. I agree with you that my test script is not exactly the same situation and the test you sent (just for the sake of completeness) me was inconclusive: ---- Paul's code ------------------------------------------------------ I wonder if OpenBSD gives back EINVAL for getsockname(2) when the peer has done a shutdown of the socket. Can you tell me what this program does? from socket import http://twistedmatrix.com/pipermail/twisted-python/2008-October/018503.html socket port = socket() port.bind(('', 0)) port.listen(1) client = socket() client.setblocking(False) client.connect_ex(port.getsockname()) server, clientAddr = port.accept() print 'Before close', server.getsockname() client.close() print 'After close', server.getsockname() If it finishes without error, try it with a time.sleep(5) before the final line. ---- end of Paul's code ------------------------------------------------ After a lot of googling there seems to be a possible onset of the problem dating back to 2006 shortly before the 4.3 release. There are other users reporting similar 'hickups' I experience on SSH and FTP, but none of those reports actually lead to a fix probably because everybody is used to a 'slow login', a typein hickup or a failed ftp. One might speculate that this could be a hardware related error but us having several servers with very different HW under similar loads and observing those errors it might be a race condition in the kernel driver. Also odd enough that the man pages for OpenBSD are the only one among the **xes who do not mention EINVAL as a possible return value but in fact do return it. I'll try to file a bug with OpenBSD but doubt that it will get much attention being so impossible to trigger it. Does somebody which is more fit on TCP/IP have an additional idea how to trigger such a behavior as described in my previous posts. Traceback below for completeness Thxs, Werner Running on twi

The environment is Linux 3.0.35. Any suggestions?Note: the OS has both IPV6 and IPV4 enabledNote error 22 invalid - Progress: the sizeof(struct sockaddr_in) comes as 16. Which can never be when we check its definition in the in.h . Any clue? buddingspacer Asked on February 12, 2015 in No Category. This question was posted in Stack Exchange Share Comment(11) Joachim Pileborg What is `RTCS_OK`? And are you sure the `socket` call succeeded? on February 12, 2015. Update Cancel buddingspacer The variable names would be diff, thats it, yes yes n_namelen is used only once and set right before call of getsockname. on February 12, 2015. Update Cancel Klas Lindbäck `n_namelen` should be of type `socklen_t`. Using `int` will definitely fail if the sizes differ. on February 12, 2015. Update Cancel Sander De Dycker what does "almost" mean ? Why not show the actual code ? A thought : are you always setting `n_namelen` right before every `getsockname` call ? Or are you somehow re-using that variable ? In the latter case, that could be your issue, since `getsockname` can modify it. on
