Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Brad Fitzpatrick	4950fe60bd	syncs, all: move to using Go's new atomic types instead of ours Fixes #5185 Change-Id: I850dd532559af78c3895e2924f8237ccc328449d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Brad Fitzpatrick	6a396731eb	all: use various net/netip parse funcs directly Mechanical change with perl+goimports. Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then goimports -d . Finally, removed the net/netaddr wrappers, to prevent future use.

Brad Fitzpatrick	7eaf5e509f	net/netaddr: start migrating to net/netip via new netaddr adapter package Updates #5162 Change-Id: Id7bdec303b25471f69d542f8ce43805328d56c12 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	55095df644	net/interfaces: get Linux default route from netlink as fallback If it's in a non-standard table, as it is on Unifi UDM Pro, apparently. Updates #4038 (probably fixes, but don't have hardware to verify) Change-Id: I2cb9a098d8bb07d1a97a6045b686aca31763a937 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	2a67beaacf	net/interfaces: bound Linux /proc/net/route parsing tailscaled was using 100% CPU on a machine with ~1M lines, 100MB+ of /proc/net/route data. Two problems: in likelyHomeRouterIPLinux, we didn't stop reading the file once we found the default route (which is on the first non-header line when present). Which meant it was finding the answer and then parsing 100MB over 1M lines unnecessarily. Second was that if the default route isn't present, it'd read to the end of the file looking for it. If it's not in the first 1,000 lines, it ain't coming, or at least isn't worth having. (it's only used for discovering a potential UPnP/PMP/PCP server, which is very unlikely to be present in the environment of a machine with a ton of routes) Change-Id: I2c4a291ab7f26aedc13885d79237b8f05c2fd8e4 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	04c2c5bd80	net/interfaces: define DefaultRouteInterface and State.DefaultRouteInterface It was pretty ill-defined before and mostly for logging. But I wanted to start depending on it, so define what it is and make Windows match the other operating systems, without losing the log output we had before. (and add tests for that) Change-Id: I0fbbba1cfc67a265d09dd6cb738b73f0f6005247 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Denton Gentry	09148c07ba	interfaces: check correct error /proc/net/route wrap io.EOF if we hit https://github.com/google/gvisor/issues/5732 Check for the correct err. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	a9745a0b68	interfaces: try larger read from /proc/net/route Work around https://github.com/google/gvisor/issues/5732 by trying to read /proc/net/route with a larger bufsize if it fails the first time. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
