2016-12-23wg: rename 'bandwidth' to 'transfer' in outputTomasz Torcz2-4/+4
'bandwidth' is a measure of speed, but wg's output shows only the number of bytes transferred. Thus 'transfer' is a better label. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-12-23wg: do not use AI_ADDRCONFIGJason A. Donenfeld1-2/+1
Some people run wg(8) using hard coded v6 addresses before interfaces have v6 addresses, causing getaddrinfo to fail. Since AI_ADDRCONFIG doesn't actualy change the sorting, but just the queries made, we don't really need AI_ADDRCONFIG anyway, since we're always only taking the first result.

2016-11-02wg: everybody hates automatic strippingJason A. Donenfeld1-1/+1
I happen to like it, but package managers don't. The GNU standard [1] says there should be a separate install-strip target. I don't like duplicating code like that. So, instead, I'll just remove stripping all together. [1] https://www.gnu.org/prep/standards/html_node/Standard-Targets.html Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-08-02c: specify static array size in function paramsJason A. Donenfeld4-10/+10
The C standard states: A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to type'', where the type qualifiers (if any) are those specified within the [ and ] of the array type derivation. If the keyword static also appears within the [ and ] of the array type derivation, then for each call to the function, the value of the corresponding actual argument shall provide access to the first element of an array with at least as many elements as specified by the size expression. By changing void func(int array[4]) to void func(int array[static 4]), we automatically get the compiler checking argument sizes for us, which is quite nice. Signed-off-by: Jason A.

This is designed to work with a server that follows this: struct sockaddr_un addr = { .sun_family = AF_UNIX, .sun_path = "/var/run/wireguard/wguserspace0.sock" }; int fd, ret; ssize_t len; socklen_t socklen; struct wgdevice *device; fd = socket(AF_UNIX, SOCK_DGRAM, 0); if (fd < 0) exit(1); if (bind(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0) exit(1); for (;;) { /* First we look at how big the next message is, so we know how much to * allocate. Note on BSD you can instead use ioctl(fd, FIONREAD, &len). */ len = recv(fd, NULL, 0, MSG_PEEK | MSG_TRUNC); if (len < 0) { handle_error(); continue; } /* Next we allocate a buffer for the received data. */ device = NULL; if (len) { device = malloc(len); if (!device) { handle_error(); continue; } } /* Finally we receive the data, storing too the return address. */ socklen = sizeof(addr); len = recvfrom(fd, device, len, 0, (struct sockaddr *)&addr, (socklen_t *)&socklen); if (len < 0) { handle_error(); free(device); continue; } if (!len) { /* If len is zero, it's a "get" request, so we send our device back. */ device = get_current_wireguard_device(&len); sendto(fd, device, len, 0, (struct sockaddr *)&addr, socklen); } else { /* Otherwise, we just received a wgdevice, so we should "set" and send back the return status. */ ret = set_current_wireguard_device(device); sendto(fd, &ret, sizeof(ret), 0, (struct sockaddr *)&addr, socklen); free(device); } } Signed-off-by: Jason A.
