[PATCH v2 4/5] ucounts: Move RLIMIT_NPROC handling after set_user

by Eric W. Biederman

During set*id() which cred->ucounts to charge the the current process to is not known until after set_cred_ucounts. So move the RLIMIT_NPROC checking into a new helper flag_nproc_exceeded and call flag_nproc_exceeded after set_cred_ucounts. This is very much an arbitrary subset of the places where we currently change the RLIMIT_NPROC accounting, designed to preserve the existing logic. Fixing the existing logic will be the subject of another series of changes. Cc: stable(a)vger.kernel.org Fixes: 21d1c5e386bc ("Reimplement RLIMIT_NPROC on top of ucounts") Signed-off-by: "Eric W.

I looked at cred->ucount and it is only used for rlimit operations that were previously stored in cred->user. Making the fact cred->ucount can refer to a different user from cred->user a bug, affecting all uses of cred->ulimit not just RLIMIT_NPROC. Fix set_cred_ucounts to always use the real uid not the effective uid. Further simplify set_cred_ucounts by noticing that set_cred_ucounts somehow retained a draft version of the check to see if alloc_ucounts was needed that checks the new->user and new->user_ns against the current_real_cred(). Remove that draft version of the check. All that matters for setting the cred->ucounts are the user_ns and uid fields in the cred.

[PATCH v2 2/5] ucounts: Enforce RLIMIT_NPROC not RLIMIT_NPROC+1

This can be fixed either by fixing the test or by moving the increment to be before the test. Fix it my moving copy_creds which contains the increment before is_ucounts_overlimit. In the case of CLONE_NEWUSER the ucounts in the task_cred changes. The function is_ucounts_overlimit needs to use the final version of the ucounts for the new process. Which means moving the is_ucounts_overlimit test after copy_creds is necessary. Both the test in fork and the test in set_user were semantically changed when the code moved to ucounts. The change of the test in fork was bad because it was before the increment. The test in set_user was wrong and the change to ucounts fixed it. So this fix only restores the old behavior in one lcation not two.

[PATCH dlm/next] fs: dlm: fix plock invalid read

by Alexander Aring

This patch fixes an invalid read showed by KASAN. A unlock will allocate a "struct plock_op" and a followed send_op() will append it to a global send_list data structure. In some cases a followed dev_read() moves it to recv_list and dev_write() will cast it to "struct plock_xop" and access fields which are only available in those structures. At this point an invalid read happens by accessing those fields. To fix this issue the "callback" field is moved to "struct plock_op" to indicate that a cast to "plock_xop" is allowed and does the additional "plock_xop" handling if set. Example of the KASAN output which showed the invalid read: [ 2064.296453] ================================================================== [ 2064.304852] BUG: KASAN: slab-out-of-bounds in

[PATCH 4/8] ucounts: Only except the root user in init_user_ns from RLIMIT_NPROC

by Eric W. Biederman

In [1] Michal Koutný <mkoutny(a)suse.com> reported that it does not make sense to unconditionally exempt the INIT_USER during fork and exec from RLIMIT_NPROC and then to impose a limit on that same user with is_ucounts_overlimit. So I looked into why the exeception was added. commit 909cc4ae86f3 ("[PATCH] Fix two bugs with process limits (RLIMIT_NPROC)") says: > If a setuid process swaps it's real and effective uids and then > forks, the fork fails if the new realuid has more processes than > the original process was limited to. This is particularly a > problem if a user with a process limit (e.g. 256) runs a > setuid-root program which does setuid() + fork() (e.g. lprng) while > root already has more than 256 process (which is quite possible). > > The root problem here is that a limit which should be a per-user > limit is being implemented as a per-process limit with per-process > (e.g. CAP_SYS_RESOURCE) controls. Being a per-user limit, it > should be that the root-user can over-ride it, not just some > process with CAP_SYS_RESOURCE. > > This patch adds a test to ignore process limits if the real user is root. With the moving of the limits from per-user to per-user-per-user_ns it is clear that testing a user_struct is no longer the proper test and the test should be a test against the ucounts struct to match the rest of the logic change that was made. With RLIMIT_NPROC not being enforced for the global root user anywhere else should it be enforced in is_ucounts_overlimit for a user namespace created by the global root user? Since this is limited to just the global root user, and RLIMIT_NPROC is already ignored for that user I am going to vote no. This change does imply that it becomes possible to limit all users in a user namespace but to not enforce the rlimits on the root user or anyone with CAP_SYS_ADMIN and CAP_SYS_RESOURCE in the user namespace. It is not clear to me why any of those exceptions exist so I figure we should until this is actually a problem for someone before we relax the permission checks here.

[PATCH 3/8] ucounts: Fix and simplify RLIMIT_NPROC handling during setuid()+execve

by Eric W. Biederman

Michal Koutný <mkoutny(a)suse.com> wrote: > The check is currently against the current->cred but since those are > going to change and we want to check RLIMIT_NPROC condition after the > switch, supply the capability check with the new cred. > But since we're checking new_user being INIT_USER any new cred's > capability-based allowance may be redundant when the check fails and the > alternative solution would be revert of the commit 2863643fb8b9 > ("set_user: add capability check when rlimit(RLIMIT_NPROC) exceeds") As of commit 2863643fb8b9 ("set_user: add capability check when rlimit(RLIMIT_NPROC) exceeds") setting the flag to see if execve should check RLIMIT_NPROC is buggy, as it tests the capabilites from before the credential change and not aftwards. As of commit 21d1c5e386bc ("Reimplement RLIMIT_NPROC on top of ucounts") examining the rlimit is buggy as cred->ucounts has not yet been properly set in the new credential. Make the code correct and more robust moving the test to see if execve() needs to test RLIMIT_NPROC into commit_creds, and defer all of the rest of the logic into execve() itself. As the flag only indicateds that RLIMIT_NPROC should be checked in execve rename it from PF_NPROC_EXCEEDED to PF_NPROC_CHECK.

[PATCH 1/8] ucounts: Fix RLIMIT_NPROC regression

by Eric W. Biederman

This can be fixed either by fixing the test or by moving the increment to be before the test. Fix it my moving copy_creds which contains the increment before is_ucounts_overlimit. This is necessary so that in the case of CLONE_NEWUSER the new credential with the new ucounts is available of is_ucounts_overlimit to test. Both the test in fork and the test in set_user were semantically changed when the code moved to ucounts. The change of the test in fork was bad because it was before the increment. The test in set_user was wrong and the change to ucounts fixed it. So this fix is only restore the old behavior in one lcatio not two.
