Attaching debdiff from 5.19-0ubuntu1 to 6.1-0.1ubuntu1: strace_5.19-0ubuntu1.dsc-to-strace_6.1-0.1ubuntu1.dsc.diff

I've removed the change related to kexec_file_load because our build/test machines arm64+armhf machines should have kernels recent enough now.
I'd also like to remove other patches but we can do this during the 23.10 cycle (this will require running on test machines which I don't have access to myself).

There's a work-around for the following issue:
- strace testsuite creates huge but sparse files
- autopkgtest calls tar with -S/--sparse
- tar reads the huge-but-sparse files in full and expands them
- this increase storage requirements by 2*3TB of storage which machines probably don't have
- build fails

I'll see during the stabilization of 23.04 or development of 23.10 if I can reproduce that outside of debian packaging and if so, discuss that issue upstream.

Hi Adrien, thanks for your work on this. It looks like we're past Feature Freeze, therefore this fix will need an FFE, or Feature Freeze Exception, as documented here: https://wiki.ubuntu.com/FreezeExceptionProcess

While I will keep ~ubuntu-sponsors subscribed, there is a chance this will need to land next cycle.

Thanks again.

I plan to file an FFe for that and it might serve for other strace updates: the strace version needs to be at least equal to the kernel version (which makes a lot of sense actually).

[Adrien Nader (adrien)]

Requesting an FFE for this update. I discussed this with Steve who actually granted the exception orally but I wanted to go through the process mostly to learn and practice the process (and also because it is likely we will need other FFes for strace in order to keep up with the kernel and having this written once could help for these).

The reason to request this FFe is that the strace version must match the kernel version due to how coupled the two are. The strace version can be actually be higher since strace stays compatible with older kernels and the kernel tries to not break userspace. Since lunar will have Linux 6.1, it should also have strace >= 6.1. Since the versionning is the same as the kernel's, the change from 5.19 to 6.1 is in no way major and breaking.

The changes are pretty simple: mostly updates to match Linux 6.1 and some improvements for terminal ioctl, PTP_* ioctl and setns syscall.

I have tested the updated package on my machine. It installs cleanly, I was able to strace find, ls, touch and other simple commands. Its own testsuite also passed on my machine during packaging.

There are full debdiffs for this strace merge (which happens to line up with Debian's freeze) earlier in this bug. As for the requested files, I'll be copying short ones (install log, NEWS) below and attaching others (ChangeLog, build log).
