Hi, I'm getting an error message when trying to "enter" into zip archive. The error is the following: file -L -z xxx.zip xxx.zip: Bad system call The call is here: https://github.com/MidnightCommander/mc/blob/master/src/filemanager/ext.c#L75 "file -z" A quick workaround is to add "-S" option: -S, --no-sandbox On systems where libseccomp (https://github.com/seccomp/libseccomp) is available, the -S flag disables sandboxing which is enabled by default. This option is needed for file to execute ex‐ ternal decompressing programs, i.e. when the -z flag is specified and the built-in decompressors are not available. On systems where sandboxing is not available, this option has no effect. You might know a better solution Upstream bug is here: https://midnight-commander.org/ticket/4219 ---------------- emerge --info Portage 3.0.13 (python 3.9.2-final-0,

Thanks for the report. Let's start off with the easy bit and hope that it's that: what version of sys-apps/file? (please show emerge -pvO sys-apps/file and emerge --info). We may get lucky and find that bug 771096 has already resolved your case. If not, can you provide strace output (in addition to above information) like in that bug, of file failing on a zip file of yours? We need to know exactly which syscall is being made.

Created attachment 692205 [details] zip file with the issue I tried few zip files and facing this problem with all of them. So here is the smallest I found
I can reproduce and confirm this. The --uncompress option with .zip files causes an invalid system call for me as well.
Created attachment 692229 [details] Strace output
same here
I can confirm, and not only zip archives are affected, but also at least: lzma, xz, zstd

Something which would help a bit, is if anybody could fire up gdb on file with debugging symbols and show us a backtrace of when this happens.
I suspect the file command is working as designed. The seccomp policy installed by file prohibits execution of external commands, but it needs to call unzip to look "inside" a zip file. This is even mentioned in the manpage that was quoted in comment 0. I think app-misc/mc would need to be updated to stop passing "-z" to file, or to add the "-S" option.

I'd argue an error should be thrown rather than letting the filter kill it, but yes.
> I'd argue an error should be thrown rather than letting the filter kill it The end result would be the same, but I suppose the error message could be improved. It might make sense to request that as an enhancement upstream.
This was fixed in mc upstream last month. Probably just needs a release or a backport. https://github.com/MidnightCommander/mc/commit/1ed638d66cf803f69ac12ee80a72d217f2146e43
1. Does mc-9999 work for you? 2. Upstream asks follow-up questions at https://midnight-commander.org/ticket/4219. Can you provide answers?
