Aaron Klotz	c17a817769	util/osdiag: add logging for winsock layered service providers to Windows bugreports ... The Layered Service Provider (LSP) is a deprecated (but still supported) mechanism for inserting user-mode DLLs into a filter chain between the Winsock API surface (ie, ws2_32.dll) and the internal user-mode interface to the networking stack. While their use is becoming more rare due to the aforementioned deprecation, it is still possible for third-party software to install their DLLs into this filter chain and interfere with Winsock API calls. Knowing whether this is happening is useful for troubleshooting. Fixes https://github.com/tailscale/tailscale/issues/8142 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	1 year ago
Aaron Klotz	37925b3e7a	go.mod, cmd/tailscaled, ipn/localapi, util/osdiag, util/winutil, util/winutil/authenticode: add Windows module list to OS-specific logs that are written upon bugreport ... * We update wingoes to pick up new version information functionality (See pe/version.go in the https://github.com/dblohm7/wingoes repo); * We move the existing LogSupportInfo code (including necessary syscall stubs) out of util/winutil into a new package, util/osdiag, and implement the public LogSupportInfo function may be implemented for other platforms as needed; * We add a new reason argument to LogSupportInfo and wire that into localapi's bugreport implementation; * We add module information to the Windows implementation of LogSupportInfo when reason indicates a bugreport. We enumerate all loaded modules in our process, and for each one we gather debug, authenticode signature, and version information.
