Title: cat doesn't handle EPERM Status in coreutils-from package in Ubuntu: Incomplete Status in rust-coreutils package in Ubuntu: Confirmed Status in util-linux package in Ubuntu: Confirmed Bug description: This was found while investigating FTBFS in util-linux (https://launchpadlibrarian.net/797485933/buildlog_ubuntu-questing- amd64.util-linux_2.41-4ubuntu1_BUILDING.txt.gz). This is triggered by this test: tests/ts/lsfd/mkfds-multiplexing This test was skipped with GNU coreutils, because at some point, `cat` fails (with reason) to read a file: https://github.com/util-linux/util-linux/blob/35128888075ade600413092214b62acf3601ead9/tests/ts/lsfd/mkfds-multiplexing#L49-L55 With uutils coreutils, the test is not skipped, but fails for unclear reasons. It boils down to this very easy reproducer: cat /proc/$$/syscall GNU coreutils output: skia@noble:/$ cat /proc/$$/syscall cat: /proc/208/syscall: Operation not permitted skia@noble:/$ echo $? 1 uutils coreutils output: skia@questing:/$ cat /proc/$$/syscall skia@questing:/$ echo $? 0 `strace cat /proc/$$/syscall` clearly shows that `read()` return EPERM with both binaries: ... read(3, 0x7ffd4ef80798, 65536) = -1 EPERM (Operation not permitted) ...
