[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patches apply w/o changes, not yet built, not yet tested
+ x86_64-musl patches not yet working, still trying to adjust them
+ ppc64le patch removed for now as nothing applies (already upstreamed?)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294
-Change-Id: I11103d1867c7196c1de92e72f9f12dcfd31c29f1

There is an updated pull request by pullmoll against master on the void-packages repository
https://github.com/pullmoll/void-packages chromium
https://github.com/void-linux/void-packages/pull/29205
[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patches apply w/o changes, not yet built, not yet tested
+ x86_64-musl patches not yet working, still trying to adjust them
+ ppc64le patch removed for now as nothing applies (already upstreamed?)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do

Subject: [PATCH] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, not yet tested
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed?)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.

-Bug: 819294

-Subject: [PATCH] GCC: fix attribute on function definition
-
-GCC does not accept attributes at the end for function definitions.
-Solution is to move it before function name. Otherwise GCC fails like
-this:
-
-../../base/compiler_specific.h:97:28: error: attributes are not allowed
-on a function-definition
- 97 | #define WARN_UNUSED_RESULT __attribute__((warn_unused_result))
- | ^~~~~~~~~~~~~

- expansion of macro 'WARN_UNUSED_RESULT'

https://github.com/pullmoll/void-packages chromium
https://github.com/void-linux/void-packages/pull/29205
[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, not yet tested
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed? need to check again)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294
-Change-Id: I11103d1867c7196c1de92e72f9f12dcfd31c29f1

-(updated to use DCHECK as suggested in comments)

There is an updated pull request by pullmoll against master on the void-packages repository
https://github.com/pullmoll/void-packages chromium
https://github.com/void-linux/void-packages/pull/29205
[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, not yet tested
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed? need to check again)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

Subject: [PATCH] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed?)
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.

-Bug: 819294

[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed?)
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do

CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, not yet tested
+ patches/ppc64le-ppc64le-support.patch removed for now (already upstreamed? need to check again)
+ files/musl-paches/xxx-ppc64le-support.patch stripped down to what still applies
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294
-Change-Id: I11103d1867c7196c1de92e72f9f12dcfd31c29f1
-
-(updated to use DCHECK as suggested in comments)

Comment:
Not sure if the x86_64-musl syscall crash is because of me already using musl-1.2.2.
I'll check to see what syscall 0324 is and what to do about it.

I suppose it's 324 `__NR_membarrier` and not 0324 (octal) as printed in the crash log.

Edit: I need to partially restore the sandbox-membarrier.patch. The `#if !defined(_NR_membarrier)` are now in the headers while the `case _NR_membarrier:` is missing in `syscall_sets.cc`.

Comment:
Do you have it in your repository for musl? The current version doesn't crash on musl 1.2.1, at least. I haven't updated to 1.2.2 because it breaks Firefox seccomp (Firefox needs to be built for musl 1.2.2).

I'll rebuild x86_64-musl with that.

[WIP] chromium: update to 89.0.4389.72
CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, "Aw, Snap!" in a VM
seccomp-bpf failure in syscall 0324
+ patches/ppc64le-ppc64le-support.patch removed for now (already upstreamed? need to check again)
+ files/musl-paches/xxx-ppc64le-support.patch stripped down to what still applies
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294
-Change-Id: I11103d1867c7196c1de92e72f9f12dcfd31c29f1

-(updated to use DCHECK as suggested in comments)

Updated: `patches/sandbox-membarrier.patch` now just adds the `case _NR_membarrier:` line and I'm rebuilding x86_64-musl now.

Updated: `patches/sandbox-membarrier.patch` now just adds the `case _NR_membarrier:` line and I'm rebuilding x86_64-musl now.
Status update: x86_64-musl does not immediately crash but soon after when viewing a website:
`libva error: vaGetDriverByNameIndex() failed with unknown libva error, driver name = (null)`

https://github.com/void-linux/void-packages/pull/29205#issuecomment-789948339
Comment:
why are you removing patches that apply? (e.g. `no-getcontext.patch`, the `libc_malloc.patch` should probably stay as well, etc)
`xxx-ppc64le-support.patch` just needs a trivial 5-minute rebase so idk why you're removing it https://gist.github.com/q66/3b7ec52349d4d7390456e3f10726b38f (but i did it myself since i don't trust anyone else not to mess it up)
you'll find that `xxx-ppc64le-support.patch` in musl patches then applies cleanly, without removing any of it (i.e. revert your changes to it)

https://voidlinux.org/ shows and does not crash... this requires further investigation :-(

[WIP] chromium: update to 89.0.4389.72
CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, "Aw, Snap!" in a VM
seccomp-bpf failure in syscall 0324
+ patches/xxx-ppc64le-support.patch removed for now (already upstreamed? need to check again)
+ files/musl-paches/xxx-ppc64le-support.patch stripped down to what still applies
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294

-Subject: [PATCH] GCC: fix attribute on function definition
-
-GCC does not accept attributes at the end for function definitions.
-Solution is to move it before function name. Otherwise GCC fails like
-this:
-
-../../base/compiler_specific.h:97:28: error: attributes are not allowed
-on a function-definition
- 97 | #define WARN_UNUSED_RESULT __attribute__((warn_unused_result))
- | ^~~~~~~~~~~~~

- expansion of macro 'WARN_UNUSED_RESULT'

Comment:
well I'm not expecting it to be finished, i'm just saying the patches tend to depend on each other, so by making patches later in the sequence apply after removing patches earlier in the sequence is just wasting your time (and may result in bugs being introduced by accident)

There is an updated pull request by pullmoll against master on the void-packages repository
https://github.com/pullmoll/void-packages chromium
https://github.com/void-linux/void-packages/pull/29205
[WIP] chromium: update to 89.0.4389.72
CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, "Aw, Snap!" in a VM
seccomp-bpf failure in syscall 0324
+ patches/xxx-ppc64le-support.patch removed for now (already upstreamed? need to check again)
+ files/musl-paches/xxx-ppc64le-support.patch stripped down to what still applies
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294

[WIP] chromium: update to 89.0.4389.72
CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, works but can crash, see comments below
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.
-
-Bug: 819294

-Subject: [PATCH] GCC: fix attribute on function definition
-
-GCC does not accept attributes at the end for function definitions.
-Solution is to move it before function name. Otherwise GCC fails like
-this:
-
-../../base/compiler_specific.h:97:28: error: attributes are not allowed
-on a function-definition
- 97 | #define WARN_UNUSED_RESULT __attribute__((warn_unused_result))
- | ^~~~~~~~~~~~~

- expansion of macro 'WARN_UNUSED_RESULT'

There's a closed pull request on the void-packages repository
[WIP] chromium: update to 89.0.4389.72
https://github.com/void-linux/void-packages/pull/29205
Description:
CVE-2021-21166
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, cursory test in a VM
+ x86_64-musl patch set updated, built, works but can crash, see comments below
+ system opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]
If you don't want to build yourself my repo has the update for testing.
