Brad Fitzpatrick	19b0cfe89e	all: prepare for GOOS=ios in Go 1.16 Work with either way for now on iOS (darwin/arm64 vs ios/arm64). In February when Go 1.16 comes out we'll have a universal binary for darwin/arm64 (macOS) and will drop support for Go 1.15 and its darwin/amd64 meaning iOS. (it'll mean macOS).

Brad Fitzpatrick	4a92fc9dc5	portlist: fix tests on Windows when not running as Administrator Updates #50	4 years ago
Josh Bleecher Snyder	a570c27577	portlist: reduce log spam on macOS Running tailscaled on my machine yields lots of entries like: weird: missing {tcp 6060} parsePortsNetstat is filtering out loopback addresses as uninteresting. Then addProcesses is surprised to discover these listening ports, which results in spurious logging. Teach addProcesses to also ignore loopback addresses.

Brad Fitzpatrick	77cad13c70	portlist: avoid syscall audit violation logspam on Android If we don't have access, don't try, don't log, don't continue trying. Fixes #521	4 years ago

Avery Pennarun	806de4ac94	portlist: fix "readdirent: no such file or directory" errors on Linux. This could happen when a process disappeared while we were reading its file descriptor list. I was able to replicate the problem by running this in another terminal: while :; do for i in $(seq 10); do /bin/true & done >&/dev/null; wait >&/dev/null; done And then running the portlist tests thousands of times. Fixes #339. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Brad Fitzpatrick	64f6104e63	portlist: reduce log spam/scariness for portlist in mac sandbox Fixes tailscale/corp#235	5 years ago
Wendi Yu	fde384b359	Fix macOS build staticcheck used to fail on macOS (and presumably windows) due to a variable declared in a common package that was only used by the Linux build, which would prevent `redo pr` from passing on Mac. Moved variable declaration from the common file to the Linux-specific one to resolve the compiler complaint. Signed-off-by: Wendi Yu <wendi.yu@yahoo.ca>	5 years ago

Brad Fitzpatrick	2776209e49	portlist: don't depend on osexec package on ios, even if it's unused Continuation of `5bb14c07dc`. The earlier commit provided the space savings (as the linker could see through that osexec was unused at runtime), but it didn't clean up the dep graph (from go list -json or godepgraph). This removes the netstat.go file from the build too, just so the dep list looks more reasonable.	5 years ago
Brad Fitzpatrick	5bb14c07dc	portlist: don't depend on tempfork/osexec on iOS, saves 90KB This gives us 90KB more of memory on iOS, as it shrinks the NetworkExtension binary by 90KB. The netstat binary isn't available in the network extension anyway, so no point pulling in the osexec package which'll just fail to find netstat anyway.	5 years ago

Brad Fitzpatrick	120273d7f6	portlist: document, clean up, fix an open fd spike, optimize a bit I noticed portlist when looking at some profiles and hadn't looked at the code much before. This is a first pass over it. It allocates a fair bit. More love remains, but this does a bit: name old time/op new time/op delta GetList-8 9.92ms ± 8% 9.64ms ±12% ~ (p=0.247 n=10+10) name old alloc/op new alloc/op delta GetList-8 931kB ± 0% 869kB ± 0% -6.70% (p=0.000 n=10+10) name old allocs/op new allocs/op delta GetList-8 4.59k ± 0% 3.69k ± 1% -19.71% (p=0.000 n=10+10) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	9ac1dda0d9	portlist: add a lint ignore for unused function. The function is indeed unused on linux, but we want it around so that unit tests exercise the netstat logic even on linux, even if it's only used on !linux. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
