Version: 1:4.0.3-36
this bug has been introduced since 1:4.0.3-35 ... perhaps related to the
fix for #314727.
with zsh as your shell, this sequence is busted:
dotlark:~% su -m
Password:
[EMAIL PROTECTED]:~# suspend
zsh: suspended su -m
i'm pretty sure this is because bash and tcsh create their own process
group at startup, and zsh doesn't... so zsh shares the same process group
as the su process.
suppose we have this pstree fragment:
zsh(4782,dean)---su(4788,root)---zsh(4789)
both pids 4788 and 4789 have pgrp 4788.
ok this is gross... but this seems to fix the problems. at first i tried
just adding the setpgrp... but with that the su'd zsh doesn't ever seem to
wake up.
so i threw in the TIOCSPGRP calls to pass the tty pgrp to the su'd zsh...
and that fixes it.
it looks like bash calls TIOCSPGRP

You mean if(setpgrp()) exit(1);?

both pids 4788 and 4789 have pgrp 4788. when zsh
suspends itself it sends SIGTSTP to -4788. this TSTP hits
both zsh(4789) and su(4788) -- which causes zsh(4782)
to finish its waitpid (it was waiting on su(4788)).

As I already said, I'd just prefer to block/ignore
several signals like TSTP.
I did the same as in src/newgrp.c in our current shadow.
I don't currently want to use sigprocmask() in su.
Most probably I'll do the same as in upstream
Hopefully we will release an

block everything (except TERM and ALRM) until exit...
