[PATCH OLK-6.6] ubifs: Queue up space reservation tasks if retrying many times

There are 2 empty LEBs used for index nodes, which is calculated as min_idx_lebs - idx_lebs = 2. In theory, LEB 15 and 33 should be reclaimed as free state after committing, but it is now in taken state. After looking the realization of reserve_space(), there's a possible situation: LEB 15: free 2000 dirty 248000 used 3952 (jhead 2) LEB 23: free 2000 dirty 248104 used 3848 (bud, taken) LEB 33: free 2000 dirty 251952 used 0 (bud, taken) wb_workfn wb_workfn_2 do_writepage // write 3000 bytes ubifs_jnl_write_data make_reservation reserve_space ubifs_garbage_collect ubifs_find_dirty_leb // ret ENOSPC, dirty LEBs are taken nospc_retries++ // 1 ubifs_run_commit do_commit LEB 15: free 2000 dirty 248000 used 3952 (jhead 2) LEB 23: free 2000 dirty 248104 used 3848 (dirty) LEB 33: free 2000 dirty 251952 used 0 (dirty) do_writepage // write 2000 bytes for 3 times ubifs_jnl_write_data // grabs 15\23\33 LEB 15: free 0 dirty 248000 used 5952 (bud, taken) LEB 23: free 0 dirty 248104 used 5848 (jhead 2) LEB 33: free 0 dirty 253952 used 0 (bud, taken) reserve_space ubifs_garbage_collect ubifs_find_dirty_leb // ret ENOSPC, dirty LEBs are taken if (nospc_retries++ < 2) // false ubifs_ro_mode ! Fetch a reproducer in Link. The dirty LEBs could be grabbed by other threads, which fails finding dirty LEBs of GC in current thread, so make_reservation() could try many times to invoke GC&&committing, but current realization limits the times of retrying as 'nospc_retries'(twice). Fix it by adding a wait queue, start queuing up space reservation tasks when someone task has retried gc + commit for many times. Then there is only one task making space reservation at any time, and it can always make success under the premise of correct budgeting.

[PATCH openEuler-1.0-LTS] net/sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve
by Zhengchao Shao 31 Jan '24

31 Jan '24

From: Pedro Tammela <pctammela(a)mojatatu.com> stable inclusion from stable-v4.19.297 commit a39a303c06dffaf851e418d814808f5eae669de2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I902AI CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a13b67c9a015c4e21601ef9aa4ec9c5d972df1b4 upstream. Christian Theune says: I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script, leaving me with a non-functional uplink on a remote router. A 'rt' curve cannot be used as a inner curve (parent class), but we were allowing such configurations since the qdisc was introduced. Such configurations would trigger a UAF as Budimir explains: The parent will have vttree_insert() called on it in init_vf(), but will not have vttree_remove() called on it in update_vf() because it does not have the HFSC_FSC flag set. The qdisc always assumes that inner classes have the HFSC_FSC flag set. This is by design as it doesn't make sense 'qdisc wise' for an 'rt' curve to be an inner curve. Budimir's original patch disallows users to add classes with a 'rt' parent, but this is too strict as it breaks users that have been using 'rt' as a inner class. Another approach, taken by this patch, is to upgrade the inner 'rt' into a 'sc', warning the user in the process. It avoids the UAF reported by Budimir while also being more permissive to bad scripts/users/code using 'rt' as a inner class. Users checking the `tc class ls [...]` or `tc class get [...]` dumps would observe the curve change and are potentially breaking with this change. v1->v2: https://lore.kernel.org/all/20231013151057.2611860-1-pctammela@mojatatu.com/ - Correct 'Fixes' tag and merge with revert (Jakub) Cc: Christian Theune <ct(a)flyingcircus.io> Cc: Budimir Markovic <markovicbudimir(a)gmail.com> Fixes: b3d26c5702c7 ("net/sched: sch_hfsc: Ensure inner classes have fsc curve") Signed-off-by: Pedro Tammela <pctammela(a)mojatatu.com> Acked-by: Jamal Hadi Salim <jhs(a)mojatatu.com> Link: https://lore.kernel.org/r/20231017143602.3191556-1-pctammela@mojatatu.com Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Zhengchao Shao <shaozhengchao(a)huawei.com> --- net/sched/sch_hfsc.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/net/sched/sch_hfsc.c b/net/sched/sch_hfsc.c index 60e71a4ce0af..bb9b42002708 100644 --- a/net/sched/sch_hfsc.c +++ b/net/sched/sch_hfsc.c @@ -913,6 +913,14 @@ hfsc_change_usc(struct hfsc_class *cl, struct tc_service_curve *usc, cl->cl_flags |= HFSC_USC; } +static void +hfsc_upgrade_rt(struct hfsc_class *cl) +{ + cl->cl_fsc = cl->cl_rsc; + rtsc_init(&cl->cl_virtual, &cl->cl_fsc, cl->cl_vt, cl->cl_total); + cl->cl_flags |= HFSC_FSC; +} + static const struct nla_policy hfsc_policy[TCA_HFSC_MAX + 1] = { [TCA_HFSC_RSC] = { .len = sizeof(struct tc_service_curve) }, [TCA_HFSC_FSC] = { .len = sizeof(struct tc_service_curve) }, @@ -1021,10 +1029,6 @@ hfsc_change_class(struct Qdisc *sch, u32 classid, u32 parentid, if (parent == NULL) return -ENOENT; } - if (!(parent->cl_flags & HFSC_FSC) && parent != &q->root) { - NL_SET_ERR_MSG(extack, "Invalid parent - parent class must have FSC"); - return -EINVAL; - } if (classid == 0 || TC_H_MAJ(classid ^ sch->handle) != 0) return -EINVAL; @@ -1077,6 +1081,12 @@ hfsc_change_class(struct Qdisc *sch, u32 classid, u32 parentid, cl->cf_tree = RB_ROOT; sch_tree_lock(sch); + /* Check if the inner class is a misconfigured 'rt' */ + if (!(parent->cl_flags & HFSC_FSC) && parent != &q->root) { + NL_SET_ERR_MSG(extack, + "Forced curve change on parent 'rt' to 'sc'"); + hfsc_upgrade_rt(parent); + } qdisc_class_hash_insert(&q->clhash, &cl->cl_common); list_add_tail(&cl->siblings, &parent->children); if (parent->level == 0) -- 2.34.1
