[PATCH openEuler-1.0-LTS] tracing/kprobes: Do the notrace functions check without kprobes on ftrace
by Liu Chuang 31 Jan '24

31 Jan '24

From: Masami Hiramatsu <mhiramat(a)kernel.org> stable inclusion from stable-v4.19.169 commit 4ec3187d17c6915f02e40b2c7b1f41d0fdda1eb4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9093Z CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7bb83f6fc4ee84e95d0ac0d14452c2619fb3fe70 upstream. Enable the notrace function check on the architecture which doesn't support kprobes on ftrace but support dynamic ftrace. This notrace function check is not only for the kprobes on ftrace but also sw-breakpoint based kprobes. Thus there is no reason to limit this check for the arch which supports kprobes on ftrace. This also changes the dependency of Kconfig. Because kprobe event uses the function tracer's address list for identifying notrace function, if the CONFIG_DYNAMIC_FTRACE=n, it can not check whether the target function is notrace or not.

Hence adding the missing read memory barrier to fix this. This is a Load-Load reordering issue, which only occurs on some weak mem-ordering architectures (e.g. ARM64, ALPHA), but not on strong mem-ordering architectures (e.g. X86). And theoretically the problem doesn't only happen on ext4, filesystems that call filemap_read() but don't hold inode lock (e.g. btrfs, f2fs, ubifs ...) will have this problem, while filesystems with inode lock (e.g. xfs, nfs) won't have this problem.

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

'pci_stop_and_remove_bus_device_locked()' will be called. This function will get the global mutex lock 'pci_rescan_remove_lock', and remove the slot. If the irq thread 'pciehp_ist' is still running, we will wait until it exits. If a pciehp interrupt happens immediately after we remove the slot by sysfs, but before we free the pciehp irq in 'pci_stop_and_remove_bus_device_locked()'. 'pciehp_ist' will hung because the global mutex lock 'pci_rescan_remove_lock' is held by the sysfs operation. But the sysfs operation is waiting for the pciehp irq thread 'pciehp_ist' ends. Then a hung task occurs. So this two kinds of operation, removing through attention buttion and removing through /sys/devices/pci***/remove, should not be excuted at the same time. This patch add a global variable to mark that one of these operations is under processing. When this variable is set, if another operation is requested, it will be rejected. We use a global variable 'slot_being_removed_rescaned' to mark whether a slot is being removed or rescaned. This will cause a slot hotplug operation is delayed if another slot is being remove or rescaned. But if these two slots are under different root ports, they should not influence each other. This patch make the flag 'slot_being_removed_rescanned' per root port so that one slot hotplug operation doesn't influence slots below another root port. We record the root port in struct pci_dev when the pci device is initialized and added into the system instead of using 'pcie_find_root_port()' to find the root port when we need it. Because iterating the pci tree needs the protection of 'pci_lock_rescan_remove()'. This will make the problem more complexed because the lock is very coarse-grained. We don't need to worry about 'use-after-free' because child pci devices are always removed before the root port device is removed.

[PATCH OLK-5.10] tcp: add sanity checks to rx zerocopy
by Zhengchao Shao 30 Jan '24

30 Jan '24

From: Eric Dumazet <edumazet(a)google.com> maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8ZTOK Reference: https://lore.kernel.org/all/20240125103317.2334989-1-edumazet@google.com/ -------------------------------- TCP rx zerocopy intent is to map pages initially allocated from NIC drivers, not pages owned by a fs. This patch adds to can_map_frag() these additional checks: - Page must not be a compound one. - page->mapping must be NULL. This fixes the panic reported by ZhangPeng. syzbot was able to loopback packets built with sendfile(), mapping pages owned by an ext4 file to TCP rx zerocopy. r3 = socket$inet_tcp(0x2, 0x1, 0x0) mmap(&(0x7f0000ff9000/0x4000)=nil, 0x4000, 0x0, 0x12, r3, 0x0) r4 = socket$inet_tcp(0x2, 0x1, 0x0) bind$inet(r4, &(0x7f0000000000)={0x2, 0x4e24, @multicast1}, 0x10) connect$inet(r4, &(0x7f00000006c0)={0x2, 0x4e24, @empty}, 0x10) r5 = openat$dir(0xffffffffffffff9c, &(0x7f00000000c0)='./file0\x00', 0x181e42, 0x0) fallocate(r5, 0x0, 0x0, 0x85b8) sendfile(r4, r5, 0x0, 0x8ba0) getsockopt$inet_tcp_TCP_ZEROCOPY_RECEIVE(r4, 0x6, 0x23, &(0x7f00000001c0)={&(0x7f0000ffb000/0x3000)=nil, 0x3000, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, &(0x7f0000000440)=0x40) r6 = openat$dir(0xffffffffffffff9c, &(0x7f00000000c0)='./file0\x00', 0x181e42, 0x0) Fixes: 93ab6cc69162 ("tcp: implement mmap() for zero copy receive") Link: https://lore.kernel.org/netdev/5106a58e-04da-372a-b836-9d3d0bd2507b@huawei.… Reported-and-bisected-by: ZhangPeng <zhangpeng362(a)huawei.com> Signed-off-by: Eric Dumazet <edumazet(a)google.com> Cc: Arjun Roy <arjunroy(a)google.com> Cc: Matthew Wilcox <willy(a)infradead.org> Cc: linux-mm(a)vger.kernel.org Cc: Andrew Morton <akpm(a)linux-foundation.org> Cc: linux-fsdevel(a)vger.kernel.org Conflicts: net/ipv4/tcp.c Signed-off-by: Zhengchao Shao <shaozhengchao(a)huawei.com> --- net/ipv4/tcp.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/net/ipv4/tcp.c b/net/ipv4/tcp.c index dcbc5ec00da8..bb74fc0aa2d2 100644 --- a/net/ipv4/tcp.c +++ b/net/ipv4/tcp.c @@ -1917,6 +1917,8 @@ static int tcp_zerocopy_receive(struct sock *sk, ret = 0; curr_addr = address; while (length + PAGE_SIZE <= zc->length) { + struct page *page; + if (zc->recv_skip_hint < PAGE_SIZE) { u32 offset_frag; @@ -1944,7 +1946,10 @@ static int tcp_zerocopy_receive(struct sock *sk, if (!frags || offset_frag) break; } - if (skb_frag_size(frags) != PAGE_SIZE || skb_frag_off(frags)) { + + page = skb_frag_page(frags); + if (skb_frag_size(frags) != PAGE_SIZE || skb_frag_off(frags) || + PageCompound(page) || page->mapping) { int remaining = zc->recv_skip_hint; while (remaining && (skb_frag_size(frags) != PAGE_SIZE || @@ -1955,7 +1960,7 @@ static int tcp_zerocopy_receive(struct sock *sk, zc->recv_skip_hint -= remaining; break; } - pages[pg_idx] = skb_frag_page(frags); + pages[pg_idx] = page; pg_idx++; length += PAGE_SIZE; zc->recv_skip_hint -= PAGE_SIZE; -- 2.34.1

[PATCH openEuler-22.03-LTS-SP2] drm/atomic: Fix potential use-after-free in nonblocking commits
by Guo Mengqi 30 Jan '24

30 Jan '24

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7V6NJ CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7V6NJ CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.
