Bjørn Forsman ed0cee645f audit-tmpdir hook: use abspath matching on RPATH entries
This ensures that RPATH entries like "/foo/build/bar" doesn't trigger a
match when TMPDIR is "/build/bar". (I've had this problem with a
prebuilt package.)

autoPatchelfHook: Skip on missing segment headers
If the file in question is not a shared object file but an ELF, we
really want to skip the file, because we won't have anything to patch
there.

For example if the file is created via "gcc -c -o foo.o foo.c", we don't
get a segment header and so far autoPatchelf was trying to patch such a
file.

By checking for missing segment headers, we're now no longer going to
attempt patching such a file.

autoPatchelfHook: Add addAutoPatchelfSearchPath
This function is useful if autoPatchelf is invoked during some of the
phases of a build and allows to add arbitrary shared objects to the
search path.

So far the same functionality was in autoPatchelf itself, but not
available as a separate function, so when adding shared objects to the
dependency cache one would have to do so manually.

The function also has the --no-recurse flag, which prevents recursing
into subdirectories.

autoPatchelfHook: Add --no-recurse flag
This is to be used with the autoPatchelf command and allows to only
patch a specific file or directory without recursing into
subdirectories.

Apart from being able to run the command in a standalone way, as
detailled in the previous commit this is also needed for the Android SDK
emulator, because according to @svanderburg there are subdirectories we
don't want to patch.

The reason why I didn't use GNU getopt is that it might not be available
on all operating systems and the getopts bash builtin doesn't support
long arguments. Apart from that, the implementation for recognizing the
flag is pretty trivial and it's also using bash builtins only, so if we
want to do something really fancy someday, we can still change it.

autoPatchelfHook: Allow to prevent automatic run
If you want to only run autoPatchelf on a specific path and leave
everything else alone, we now have a $dontAutoPatchelf environment
variable, which causes the postFixup hook to not run at all.

The name "dontAutoPatchelf" probably is a bit weird in conjunction with
putting "autoPatchelfHook" in nativeBuildInputs, but unless someone
comes up with a better name I keep it that way because it's consistent
with all the other dontStrip, dontPatchShebangs, dontPatchELF and
whatnot.

A specific example where this is needed is when building the Android SDK
emulator, which contains a few ARM binaries in subdirectories that
should not be patched. If we were to run autoPatchelf on all outputs
unconditionally we'd run into errors because some ARM libraries couldn't
be found.

autoPatchelfHook: Make easier to run autoPatchelf
The autoPatchelf main function which is run against all of the outputs
was pretty much tailored towards this specific setup-hook and was
relying on $prefix to be set globally.

So if you wanted to run autoPatchelf manually - let's say during
buildPhase - you would have needed to run it like this:

  prefix=/some/directory autoPatchelf

This is now more intuitive and all you need to do is run the following:

  autoPatchelf /some/directory

tmpdir audit: only fail with files referenced below (#35068)
On Linux the `$TMPDIR` is `/build`. The TMPDIR audit looks for `$TMPDIR`
in the build output, which will then fail with packages like
/buildkite-agent.

This fixes the heuristic to look for `$TMPDIR/` instead.

autoPatchelfHook: Correctly detect PIE binaries
I originally thought it would just be enough to just check for an INTERP
section in isExecutable, however this would mean that we don't detect
statically linked ELF files, which would break our recent improvement to
gracefully handle those.

In theory, we are only interested in ELF files that have an INTERP
section, so checking for INTERP would be enough. Unfortunately the
isExecutable function is already used outside of autoPatchelfHook, so we
can't easily get rid of it now, so let's actually strive for more
correctness and make isExecutable actually match ELF files that are
executable.

So what we're doing instead now is to check whether either the ELF type
is EXEC *or* we have an INTERP section and if one of them is true we
should have an ELF executable, even if it's statically linked.

Along the way I also set LANG=C for the invocations of readelf, just to
be sure we don't get locale-dependent output.

Tested this with the following command (which contains almost[1] all the
packages using autoPatchelfHook), checking whether we run into any
library-related errors:

  nix-build -E 'with import ./. { config.allowUnfree = true; };
    runCommand "test-executables" {
      drvs = [
        anydesk cups-kyodialog3 elasticsearch franz gurobi
        masterpdfeditor oracle-instantclient powershell reaper
        sourcetrail teamviewer unixODBCDrivers.msodbcsql17 virtlyst
        vk-messenger wavebox zoom-us
      ];
    } ("for i in $drvs; do for b in $i/bin/*; do " +
       "[ -x \"$b\" ] && timeout 10 \"$b\" || :; done; done")
  '

Apart from testing against library-related errors I also compared the
resulting store paths against the ones prior to this commit. Only
anydesk and virtlyst had the same as they didn't have self-references,
everything else differed only because of self-references, except
elasticsearch, which had the following PIE binaries:

  * modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/autoconfig
  * modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/autodetect
  * modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/categorize
  * modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller
  * modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/normalize

These binaries were now patched, which is what this commit is all about.

In strictDeps=false, autoPatchshebangs should use
--build (corresponding to PATH) to lookup commands. This restores the
previous behavior of patchshebangs so that we don’t break stuff that

breakpointHook: add for debugging failing builds
Usuage: Add breakpointHook to your `buildInputs` like this:

  stdenv.mkDerivation rec {
    # ...
    buildInputs = [ breakpointHook ];
  });

When the build fails as show in this example:

  pkgs.hello.overrideAttrs (old: {
    buildInputs = [ breakpointHook ];
    postPatch = ''
      false
    '';
  });

It will halt execution printing the following message:

To attach to this build run the following command as root:

   cntr attach -t command cntr-/nix/store/ynyb4n82x2r7sldd58pbb405jdqh5f00-hello-2.10

Installing cntr and running the command will provide shell access to the
build sandbox of failed build:

Revert "patch-shebangs: respect cross compilation"
This causes problems for packages built using a bootstrap stdenv,
resulting in references to /bin/sh or even bootstrap-tools. The darwin
stdenv is much stricter about what requisites/references are allowed but
using /bin/sh on linux is also undesirable.

autoPatchelfHook: Silence errors in isExecutable
The "maxx" package recursively runs isExecutable on a bunch of files and
since the change to use "readelf" instead of "file" a lot of errors like
this one are printed during build:

  readelf: Error: Not an ELF file - it has the wrong magic bytes at the
  start

While the isExecutable was never meant to be used outside of the
autoPatchelfHook, it's still a good idea to silence the errors because
whenever readelf fails, it clearly indicates that the file in question
is not a valid ELF file.

autoPatchelfHook: Only check PT_INTERP on execs
If the ELF file is not an executable, we do not get a PT_INTERP section,
because after all, it's a *shared* library.

So instead of checking for PT_INTERP (to avoid statically linked
executables) for all ELF files, we add another check to see if it's an
executable and *only* skip it when it is and there's no PT_INTERP.

autoPatchelfHook: Run after patchelf's setup hook
So far the runtimeDependencies variable has been rather useless unless
you also set dontPatchelf, because the patchelf setup hook ran *after*
the autoPatchelfHook and thus stripped off the additional RPATHs added
using runtimeDependencies.

I did this by moving the autoPatchelfHook to be run in postFixup instead
of fixupOutput, however I needed to replicate the for loop that runs the
hook on all outputs.

Until we have a way to influence order of execution for hooks I've
marked this with an XXX so that we can use fixupOutput again.

Tested this against all packages that use autoPatchelfHook using the
following and checking whether the output contains any errors concerning
shared libraries:

nix-build -E 'with import ./. { config.allowUnfree = true; };
  runCommand "test-executables" {
    drvs = [
      masterpdfeditor franz zoom-us anydesk teamviewer maxx
      oracle-instantclient cups-kyodialog3 virtlyst powershell

  } "for i in $drvs; do for b in $i/bin/*; do \"$b\" || :; done; done"

pruneLibtoolFiles: init setup hook (#41819)
A .la file specifies linker flags to link with the library it describes. Its
"dependency_libs" field lists the libraries that this library depends upon.
This list often contains "-l" flags without corresponding "-L" flags. Many
packages in Nixpkgs deal with this in one of these ways:
- delete .la file [1]
- clear dependency_libs [2]
- add -L flags to dependency_libs [3]
- propagate dependencies [4]

Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev"
output with headers rather than to the main output with libraries. They have to
be edited or deleted to reduce closure size [5].

Deleting .la files is often but not always safe [6].  Atomatically deleting as
many of them as possible is complex [7].  Deleting .la files that describe
shared rather than static libraries is probably safe; but clearing their
"dependency_libs" field achieves the same effect with less potential for
unintended consequences.  This is the approach that may be enabled for all
Nixpkgs.

setup-hooks: Add autoPatchelfHook
I originally wrote this for packaging proprietary games in Vuizvui[1]
but I thought it would be generally useful as we have a fair amount of
proprietary software lurking around in nixpkgs, which are a bit tedious
to maintain, especially when the library dependencies change after an
update.

So this setup hook searches for all ELF executables and libraries in the
resulting output paths after install phase and uses patchelf to set the
RPATH and interpreter according to what dependencies are available
inside the builder.

For example consider something like this:

stdenv.mkDerivation {
  ...
  nativeBuildInputs = [ autoPatchelfHook ];
  buildInputs = [ mesa zlib ];
  ...
}

Whenever for example an executable requires mesa or zlib, the RPATH will
automatically be set to the lib dir of the corresponding dependency.

If the library dependency is required at runtime, an attribute called
runtimeDependencies can be used to list dependencies that are added to
all executables that are discovered unconditionally.

Beside this, it also makes initial packaging of proprietary software
easier, because one no longer has to manually figure out the
dependencies in the first place.
