David Anderson	63a9adeb6c	portlist: collect IPv6 listening sockets on linux. ... This is important because some of those v6 sockets are actually dual-stacked sockets, so this is our only chance of discovering some services. Fixes #1443.

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
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	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
