2022-11-08context: add APIs for writing and reading cancelation causeSameer Ajmani
Extend the context package to allow users to specify why a context was canceled in the form of an error, the "cause". Users write the cause by calling WithCancelCause to construct a derived context, then calling cancel(cause) to cancel the context with the provided cause. Users retrieve the cause by calling context.Cause(ctx), which returns the cause of the first cancelation for ctx or any of its parents. The cause is implemented as a field of cancelCtx, since only cancelCtx can be canceled. Calling cancel copies the cause to all derived (child) cancelCtxs. Calling Cause(ctx) finds the nearest parent cancelCtx by looking up the context value keyed by cancelCtxKey. API changes: +pkg context, func Cause(Context) error +pkg context, func WithCancelCause(Context) (Context, CancelCauseFunc) +pkg context, type CancelCauseFunc func(error) Fixes #26356 Fixes #51365 Change-Id: I15b62bd454c014db3f4f1498b35204451509e641 Reviewed-on: https://go-review.googlesource.com/c/go/+/375977 Reviewed-by: Damien Neil <dneil@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> Run-TryBot: Sameer Ajmani <sameer@golang.org> Auto-Submit: Sameer Ajmani <sameer@golang.org>

2022-09-09syscall: add CgroupFD support for ForkExec on LinuxKir Kolyshkin
Implement CLONE_INTO_CGROUP feature, allowing to put a child in a specified cgroup in a clean and simple way. Note that the feature only works for cgroup v2, and requires Linux kernel 5.7 or newer. Using the feature requires a new syscall, clone3. Currently this is the only reason to use clone3, but the code is structured in a way so that other cases may be easily added in the future. Add a test case. While at it, try to simplify the syscall calling code in forkAndExecInChild1, which became complicated over time because: 1. It was using either rawVforkSyscall or RawSyscall6 depending on whether CLONE_NEWUSER was set. 2. On Linux/s390, the first two arguments to clone(2) system call are swapped (which deserved a mention in Linux ABI hall of shame). It was worked around in rawVforkSyscall on s390, but had to be implemented via a switch/case when using RawSyscall6, making the code less clear. Let's - modify rawVforkSyscall to have two arguments (which is also required for clone3); - remove the arguments workaround from s390 asm, instead implementing arguments swap in the caller (which still looks ugly but at least it's done once and is clearly documented now); - use rawVforkSyscall for all cases (since it is essentially similar to RawSyscall6, except for having less parameters, not returning r2, and saving/restoring the return address before/after syscall on 386 and amd64).

The constants for these were auto-generated from the C includes into zerrors_linux* files quite some time ago. The generator is currently broken, but some new flags need to be added nevertheless. As the flags won't change and the values are the same for all architectures, we can just define them statically (as it's already done in the runtime package): - remove the CLONE_* constants from zerrors_linux_*.go; - patch mkerrors.sh to not generate CLONE_ constants (in case it will be fixed and used in the future); - add the constants and some comments about them to exec_linux.go, using Linux v5.17 include/uapi/sched.h as the ultimate source. This adds the following new flags: - CLONE_CLEAR_SIGHAND - CLONE_INTO_CGROUP - CLONE_NEWCGROUP - CLONE_NEWTIME - CLONE_PIDFD For #51246.

2022-08-16net/http/httputil: add ReverseProxy.RewriteDamien Neil
Add a new Rewrite hook to ReverseProxy, superseding the Director hook. Director does not distinguish between the inbound and outbound request, which makes it possible for headers added by Director to be inadvertently removed before forwarding if they are listed in the inbound request's Connection header. Rewrite accepts a value containing the inbound and outbound requests, with hop-by-hop headers already removed from the outbound request, avoiding this problem. ReverseProxy's appends the client IP to the inbound X-Forwarded-For header by default. Users must manually delete untrusted X-Forwarded-For values. When used with a Rewrite hook, ReverseProxy now strips X-Forwarded-* headers by default. NewSingleHostReverseProxy creates a proxy that does not rewrite the Host header of inbound requests. Changing this behavior is cumbersome, as it requires wrapping the Director function created by NewSingleHostReverseProxy. The Rewrite hook's ProxyRequest parameter provides a SetURL method that provides equivalent functionality to NewSingleHostReverseProxy, rewrites the Host header by default, and can be more easily extended with additional customizations.

2022-08-06fmt: add a function to recover the original format string given a StateRob Pike
Sometimes when implementing a Formatter it's helpful to use the fmt package without invoking the formatter. This new function, FormatString, makes that easier in some cases by recreating the original formatting directive (such as "%3.2f") that caused Formatter.Format to be called. The original Formatter interface is probably not what we would design today, but we're stuck with it. FormatString, although it takes a State as an argument, compensates by making Formatter a little more flexible. The State does not include the verb so (unlike in the issue), we must provide it explicitly in the call to FormatString. Doing it there minimizes allocations by returning the complete format string.
