KevinLiang10	243ce6ccc1	util/linuxfw: decoupling IPTables logic from linux router ... This change is introducing new netfilterRunner interface and moving iptables manipulation to a lower leveled iptables runner. For #391 Signed-off-by: KevinLiang10 <kevinliang@tailscale.com>	1 year ago
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
Denton Gentry	d2480fd508	net/netns: support !CAP_NET_ADMIN ... netns_linux checked whether "ip rule" could run to determine whether to use SO_MARK for network namespacing. However in Linux environments which lack CAP_NET_ADMIN, such as various container runtimes, the "ip rule" command succeeds but SO_MARK fails due to lack of permission. SO_BINDTODEVICE would work in these environments, but isn't tried. In addition to running "ip rule" check directly whether SO_MARK works or not. Among others, this allows Microsoft Azure App Service and AWS App Runner to work. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago

Brad Fitzpatrick	a5d6c9d616	net/netns: optimize defaultRouteInterface a bit ... It'll be called a bunch, so worth a bit of effort. Could go further, but not yet.
