[Bug 1843479] Re: gzip in Ubuntu Eoan results in Exec format error on WSL1
Hello Hayden, or anyone else affected, Accepted binutils into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/binutils/2.33-2ubuntu1.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Tags removed: verification-done verification-done-eoan ** Tags added: verification-needed verification-needed-eoan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843479 Title: gzip in Ubuntu Eoan results in Exec format error on WSL1 To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/1843479/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

* The binutils fix could cause binutils to generate invalid ELF files. The
fix is very small and isolated and has been tested and accepted by upstream,
which makes such problems unlikely.
* Bugs in the toolchain in general can make the rebuilt gzip show new

[Originial Bug Text]
Summary:
Running gzip on WSL1 results in the following error:
$ gzip
-bash: /bin/gzip: cannot execute binary file: Exec format error
What I expect to happen:
gzip executes correctly on WSL1.
What happens instead:
gzip fails with an Exec format error.
Notes:
I suspect a change in how gzip is being built for Eoan is causing issues
with ELF parsing on the WSL1 translation layer. For example:
On Disco with gzip 1.9-3:
$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux
3.2.0, BuildID[sha1]=efa859c26eaf8e035efe9a139361e2a60cd17b3e, stripped
On Eoan with gzip 1.10-0ubuntu3:
$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2,
BuildID[sha1]=bc0f5994544c2a469d04c914bf4bf44b4ded6040, for GNU/Linux 3.2.0,
stripped
Eoan ships with gzip 1.10, while Disco ships with gzip 1.9, but I do not
believe this is an issue in 1.10 because this error does not occur when
building gzip from GNU project source on Ubuntu Eoan.
Justifications:
WSL1 will need to be patched in future Windows builds for this change in
ELF. However that patch will likely not be backported to older builds of
Windows, including Windows Enterprise/Server 2019.
To ensure Eoan can run on current and older builds of Windows Ubuntu
should consider looking at how it's building gzip and see if it can be
made to 'play nice' until WSL1 can be updated.

So the binutils upload will need to be re-built against security and pushed to the -security pocket additionally to the -updates pocket, otherwise all the future potential gzip security updates would revert this fix here. Balint is preparing the rebuild, but I think ubuntu- security should be notified. In the meantime, I have released gzip as is as it does not have any runtime dependency on the new binutils. It did not age fully but I am conditionally accepting it earlier. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843479 Title: gzip in Ubuntu Eoan results in Exec format error on WSL1 To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/1843479/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1843479] Re: gzip in Ubuntu Eoan results in Exec format error on WSL1
** Description changed:
+ [Impact]
+
+ * Running gzip on WSL1 results in the following error:
+$ gzip
+-bash: /bin/gzip: cannot execute binary file: Exec format error
+ * The error occurs frequently in package updates and makes gzip inoperable
on WSL1
+ * The problem is caused by PT_LOAD offset pointing past the end of file and
the fix is fixing strip to not generate such ELF files and recompiling gzip
with the fixed strip.
+
+ [Test Case]
+
+ * Check the gzip binary for wrong offset:
+ $ FILE=/usr/bin/gzip; readelf -W --program-headers $FILE | awk -v
size=$(stat -c %s $FILE) '/^ LOAD/ {if (strtonum($2) > size) {print "wrong
offset ("$2" ("strtonum($2)") points past EOF:" size; exit 1;}}'
+
+ [ Regression Potential ]
+
+ * The binutils fix could cause binutils to generate invalid ELF files. The
fix is very small and isolated and has been tested and accepted by upstream,
which makes such problems unlikely.
+ * Bugs in the toolchain in general can make the rebuilt gzip show new
errors, but this generally applies to many SRUs and security updates. The
testing period in proposed should mitigate this risk.
+
+ [Originial Bug Text]
+
Summary:
Running gzip on WSL1 results in the following error:
$ gzip
-bash: /bin/gzip: cannot execute binary file: Exec format error
What I expect to happen:
gzip executes correctly on WSL1.
What happens instead:
gzip fails with an Exec format error.
Notes:
I suspect a change in how gzip is being built for Eoan is causing issues
with ELF parsing on the WSL1 translation layer. For example:
On Disco with gzip 1.9-3:
$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux
3.2.0, BuildID[sha1]=efa859c26eaf8e035efe9a139361e2a60cd17b3e, stripped
On Eoan with gzip 1.10-0ubuntu3:
$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2,
BuildID[sha1]=bc0f5994544c2a469d04c914bf4bf44b4ded6040, for GNU/Linux 3.2.0,
stripped
Eoan ships with gzip 1.10, while Disco ships with gzip 1.9, but I do not
believe this is an issue in 1.10 because this error does not occur when
building gzip from GNU project source on Ubuntu Eoan.
Justifications:
WSL1 will need to be patched in future Windows builds for this change in
ELF. However that patch will likely not be backported to older builds of
Windows, including Windows Enterprise/Server 2019.
To ensure Eoan can run on current and older builds of Windows Ubuntu
should consider looking at how it's building gzip and see if it can be
made to 'play nice' until WSL1 can be updated.

I tried comparing the binaries with diffoscope, and one difference which jumped out at me is the .plt.sec section which is present in the Eoan binary.
