Fix TUN core elevation: decide sudo from the config context snapshot (#9830 )
CoreManager.RunProcess decided sudo elevation from the live mutable _config.TunModeItem.EnableTun while the launched config was generated from the immutable CoreConfigContext snapshot. If the TUN state changed while a reload was in flight, a core whose config contains a TUN inbound could launch without elevation and die within the 100ms health check ("Failed to run core"), with no stderr shown. The elevation decision now follows context.IsTunEnabled / preContext.IsTunEnabled, so the generated config and the launch mode always agree. With legacy TUN protect, the sing-box pre-core hosting TUN is elevated and the main core no longer runs as root needlessly.

hyjhyj111	ee7e21268a	Fix TUN core elevation: decide sudo from the config context snapshot (#9830 ) CoreManager.RunProcess decided sudo elevation from the live mutable _config.TunModeItem.EnableTun while the launched config was generated from the immutable CoreConfigContext snapshot. If the TUN state changed while a reload was in flight, a core whose config contains a TUN inbound could launch without elevation and die within the 100ms health check ("Failed to run core"), with no stderr shown. The elevation decision now follows context.IsTunEnabled / preContext.IsTunEnabled, so the generated config and the launch mode always agree. With legacy TUN protect, the sing-box pre-core hosting TUN is elevated and the main core no longer runs as root needlessly.	2026-07-26 21:24:11 +08:00

mymyme	0427037638	fix: sanitize system proxy exceptions to avoid macOS ExceptionsList b… (#9815 ) * fix: sanitize system proxy exceptions to avoid macOS ExceptionsList being dropped On macOS/Linux the exception list is comma-separated and passed to networksetup. It was only stripped of spaces, so a stray newline or a trailing comma left a malformed/empty entry. macOS configd then silently rejects the whole ExceptionsList (scutil --proxy shows no ExceptionsList), so the bypass never takes effect. Split on ',' with TrimEntries + RemoveEmptyEntries and rejoin; behavior-preserving for well-formed input. Windows path (';') is left unchanged. Note: not built locally (no .NET SDK on hand); relying on CI. * Update SysProxyHandler.cs --------- Co-authored-by: 2dust <31833384+2dust@users.noreply.github.com>	2026-07-24 14:12:10 +08:00

Miheichev Aleksandr Sergeevich	165e0bf9e9	chore(deps): update NuGet dependencies (#9745 ) - Downloader 5.9.0 -> 5.9.4 - NLog 6.1.3 -> 6.1.4 - Repobot.SQLite.Unofficial 3.53.3 -> 3.53.3.8 - sqlite-net-e 1.11.0 -> 1.11.285 - YamlDotNet 18.0.0 -> 18.1.0 sqlite-net-e and Repobot.SQLite.Unofficial are bumped together: the newer sqlite-net-e moves to SQLitePCLRaw.config.e_sqlite3 3.0.3. SkiaSharp.NativeAssets.Linux intentionally stays at 3.119.4 to match the managed SkiaSharp resolved through Avalonia.Skia 12.1.0; bumping it alone to 4.x would compile but break rendering at runtime on Linux. It should follow Avalonia when Avalonia itself moves to SkiaSharp 4. ReactiveUI.Avalonia stays at 12.0.3: the numerically higher 14.x line targets Avalonia 11 / ReactiveUI 19 and would be an effective downgrade for the Avalonia 12 stack.	2026-07-15 19:12:56 +08:00
