Arch Linux User Repository

To those getting a segfault: coverity has built their tool using an ancient version of glibc which they statically linked. That glibc was using a deprecated kernel API, which has been disabled (for security reasons) since kernel 4.8. They need to recompile their tool with a more recent version of glibc so that it can be used on modern Linux. They are aware of the issue (they talk about it on the front page of https://scan.coverity.com, although they got confused between sysctl and linux cmdline), but they still haven't done it 2 years later.

In the mean time, the kernel feature can be re-enabled by adding vsyscall=emulate to your Linux command line, although it requires the kernel to be compiled with CONFIG_X86_VSYSCALL_EMULATION=y (which is still the case of the official linux package as of today). You can check that by running zgrep CONFIG_X86_VSYSCALL_EMULATION /proc/config.gz.

I am also getting 808190e72ae2059076c2afb8bb3f85cced5b2deb7ce80011d9b88b732d5c3d85 as the SHA-256 hash for cov-analysis-linux64-2019.03.tar.gz.

@1ace, sorry I missed your reply. Yes, I just verified this with a fresh clone/rebuild and I still need that tar/tar.gz patch; I also needed to update the checksum as I mentioned previously as well.

@pcmoore: for that .tar.gz patch, are you sure? on my machine makepkg extracts the gz and we're left with a .tar.
Please make sure you didn't have an old build directory around with random old files :)

A patch somewhat like the following is also needed:

@pcmoore: I just downloaded it a few hours ago, and noticing that the hash had updated without them bumping the version number I updated the hash (see 0cc1589ca525)

If you're seeing yet another hash, that means it's become impossible to have a stable has to check against, which means I'll need to give up on that and allow anything (ie. 'SKIP' as the hash to check against) :/

It looks like the x86_64 checksum needs to be updated:

808190e72ae2059076c2afb8bb3f85cced5b2deb7ce80011d9b88b732d5c3d85 cov-analysis-linux64-2019.03.tar.gz

FYI: I had similar problems to @Rucikir and found that the bsdtar/$PATH fixes suggested by @csslayer solved the problem.

@1ace, can we get an update to the package?

For the latest version for the tar, bsdtar --strip-components=1 -xf "${srcdir}/${_tarball}" (1 instead of 2) should be used. And also the PATH need to be updated to /opt/cov-analysis/bin accordingly.

I have this error when I try cov-build:

[ERROR] Failed to initialize ICU, try using the --prevent-root option.

How do I fix it?

FYI: it appears the checksums need to be updated. The currently available Linux x86_64 package does not match the checksum in the PKGBUILD:
