[POSSIBLE systemd's bug]Strang problem about "getgroups".
I'm working on a little learning project,need to call "getgroups(int gidsetsize, gid_t grouplist[])"
I'v got "0" result of an id should have a list.
while checking all possibilities,I found out the user's group must not be "0",or the function won't return none 0 result.
but i'm only meet this problem on my own computer.
I checked virtual machine which use manjaro or ubuntu,none of them has the problem ,
a co-league has an vps which use arch too do not has the problem.
Any suggestions?

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
the user's group must not be "0"
man 3 getgroup wrote:
DESCRIPTION
The getgroups() function shall fill in the array grouplist with the current supplementary
group IDs of the calling process. It is implementation-defined whether getgroups() also
returns the effective group ID in the grouplist array.
man 3 getgroup wrote:
DESCRIPTION
getgroups() returns the supplementary group IDs of the calling process in list. The argu‐
ment size should be set to the maximum number of items that can be stored in the buffer
pointed to by list. If the calling process is a member of more than size supplementary
groups, then an error results.It is unspecified whether the effective group ID of the calling process is included in the
returned list. (Thus, an application should also call getegid(2) and add or remove the
resulting value.)

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
I'v compared id output before the post.
Only the physical machine give me NULL list,and the strace output is different
...my machine...
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
getgroups(0, NULL) = 0
getgroups(0, []) = 0
newfstatat(AT_FDCWD, "/etc/nsswitch.conf", {st_mode=S_IFREG|0644, st_size=359, ...}, 0) = 0...
other machine's the first getgroups will return none 0 result,no matter what's the user's gid are,and then,the 2nd will use the result as the 1st para to get a list.
one of my virtual machine which use ubuntu:
getgroups(0, NULL) = 7
getgroups(7, [0, 4, 24, 27, 30, 46, 110]) = 7"id" command only return the none zero result to get "self" result but not other's because of different execution branch.
Tried edit the user's gid to none 0,after reboot,the result going to normal
Change gid back to 0 again,after reboot,the result is NULL again.
Might be something about user namespace?

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
I meant: What is the actual output of "id" of the tested users on either system?

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
arch phy machine,when gid is 0
->id
uid=1000(prosup) gid=0(root) groups=0(root)id with para "username" is correct because of different branch
->id prosup
uid=1000(prosup) gid=0(root) groups=0(root),998(wheel),1000(prosup),972(docker)arch phy machine,when gid is not 0
->id
uid=1000(prosup) gid=1000(prosup) groups=1000(prosup),0(root),998(wheel),972(docker)ubuntu test vm does not has the problem even the gid is 0
->id
uid=1000(prosup) gid=0(root) groups=0(root),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),110(lxd) Last edited by prosup (2022-11-14 03:57:46)

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
Why do you have a user who is a member of root's group? This is not at all usual (and not at all safe).
Here is my result on Arch for my ordinary user account
uid=1000(dienw) gid=1000(dienw) groups=1000(dienw),7(lp),10(wheel),100(users),1002(between)Note that I am not in root's group at all - never mind only in root's group.
[Edited because the post it responded to was edited.]

No,I'm not. The result is wrong when the gid is 0. See the 1st post.
ONLY When The GID is not zero like "1000",the result would has a list,AND THE PROBLEM is only occur on my phy machine.

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
Please post the complete straces of
strace -o /tmp/getgroup.bad id
strace -o /tmp/getgroup.good id prosupand your /etc/group and /etc/passwd (there're no passwords in the latter)
On a general matter, while this is academically interesting cfr has a very strong point that your user should™ not be in the root group at all and to begin with.
Nevertheless this isn't the expected behavior (nor reproducible here)

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
How are you manipulating your group memberships? You might have corrupted /etc/group and/or /etc/gshadow. You can use grpck to check for corruption.

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
I know "my user Should not be in root group" ,It's a testbench to work on,I will fix this later.
Found out interest "GOOD" result,when use "su" command to switch to "MYSELF"
❯ LANG=C
❯ strace -o id.bad.log id
uid=1000(prosup) gid=0(root) groups=0(root)
❯ su prosup
Password:
❯ strace -o id.good.log id
uid=1000(prosup) gid=0(root) groups=0(root),972(docker),983(systemd-journal),998(wheel),1000(prosup),below is the log ,i'm using 2 user names to do the test,the output belongs to qiyin

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
switch to i3 found interesting info:
When the process is child of (grand child etc.)
/usr/lib/systemd/systemd --usergetgroups will give bad result.
When the process is not child of upper process(the "init" got it),getgroups will give good result
-----------------edited----------------
recreate the same problem on manjaro vm
click the "konsole" icon on taskbar,the konsole will be leaf of sddm,the result is ok.

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
So, the problem might be associated with systemd?
Likely - your "good" case looks more like a local test user login ("id" - w/o any parameter!) while the bad case misses several system calls in comparism.
What happens if you
sudo -i -u prosupwithin a "bad" terminal and then run "id"?

like #10 post
su prosup or sudo -i -u prosup in "bad" terminal will produce "good" result.
Because the problem can be re-created,phy machine user remove from root group (follow cfr advise),below result comes from my vm.
[prosup@qmanjaro ~]$ id
uid=1000(prosup) gid=0(root) groups=0(root)
[prosup@qmanjaro ~]$ su prosup
Password:
[prosup@qmanjaro ~]$ id
uid=1000(prosup) gid=0(root) groups=0(root),3(sys),90(network),98(power),991(lp),998(wheel)
[prosup@qmanjaro ~]$ exit
exit
[prosup@qmanjaro ~]$ sudo -i -u prosup
[prosup@qmanjaro ~]$ id
uid=1000(prosup) gid=0(root) groups=0(root),3(sys),90(network),98(power),991(lp),998(wheel)
[prosup@qmanjaro ~]$ getgroups is a syscall as i understand,but pure user space action will affect the result is really confusing.

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".

grep -i groups /proc/556/status # PIDs taken from your tree in #11

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
The problem addressed by the url is quite alike,but not the same.Adding pam_groups.so will not solve the problem
the root process "systemd --user" result is "A NULL" list
[prosup@qmanjaro ~]$ id //which is leaf of sddm
uid=1000(prosup) gid=0(root) groups=0(root),3(sys),90(network),98(power),991(lp),998(wheel)
[prosup@qmanjaro ~]$ grep -i groups /proc/535/status //535 is the pid of systemd --user
Groups:
[prosup@qmanjaro ~]$ other process ,by root result will be
->grep -i groups /proc/657/status
Groups: 0It's another bug ?

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
Same problem, just the mitigation didn't work.
Just adding pam_group in and by itself would do noting, the user likely configured /etc/security/group.conf to get him the desired groups.
Given https://github.com/sddm/sddm/issues/1159te origina migt also be SDDM - did you ever try anoter DM?

Re: [POSSIBLE systemd's bug]Strang problem about "getgroups".
It's systemd's problem ,not DM's .tried on debian wsl(imp -s). can recreate the same problem.
I'v submitted an issue to systemd's git repo,this thread could be closed .
Thanks for help.
