[PATCH 5.10] block-map: add __GFP_ZERO flag for alloc_page in function bio_copy_kern

by Nobel Barakat

[ Upstream commit cc8f7fe1f5eab010191aa4570f27641876fa1267 ] Add __GFP_ZERO flag for alloc_page in function bio_copy_kern to initialize the buffer of a bio. Signed-off-by: Haimin Zhang <tcs.kernel(a)gmail.com> Reviewed-by: Chaitanya Kulkarni <kch(a)nvidia.com> Reviewed-by: Christoph Hellwig <hch(a)lst.de> Link: https://lore.kernel.org/r/20220216084038.15635-1-tcs.kernel@gmail.com Signed-off-by: Jens Axboe <axboe(a)kernel.dk> [nobelbarakat: Backported to 5.10: Manually added flag] Signed-off-by: Nobel Barakat <nobelbarakat(a)google.com> --- This changes fixes a kernel info leak since it's possible for bio_copy_kern to copy unitialized memory into userspace. For the backport, I had to manually add the __GFP_ZERO flag since alloc_page on 5.10 uses a different parameter than on 5.15. On 5.10, alloc_page is called with q->bounce_gfp whereas on 5.15 it's called with GFP_NOIO. Version 5.4 is also affected, and I intend to submit a backport there as well. block/blk-map.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/block/blk-map.c b/block/blk-map.c index 21630dccac62..ede73f4f7014 100644 --- a/block/blk-map.c +++ b/block/blk-map.c @@ -488,7 +488,7 @@ if (bytes > len) bytes = len; - page = alloc_page(q->bounce_gfp | gfp_mask); + page = alloc_page(q->bounce_gfp | __GFP_ZERO | gfp_mask); if (!page) goto cleanup; -- 2.36.0.464.gb9c8b46e94-goog

[PATCH 4.9 4.14] net: ipv6: ensure we call ipv6_mc_down() at most once

by Johannes Nixdorf

commit 9995b408f17ff8c7f11bc725c8aa225ba3a63b1c upstream. There are two reasons for addrconf_notify() to be called with NETDEV_DOWN: either the network device is actually going down, or IPv6 was disabled on the interface. If either of them stays down while the other is toggled, we repeatedly call the code for NETDEV_DOWN, including ipv6_mc_down(), while never calling the corresponding ipv6_mc_up() in between. This will cause a new entry in idev->mc_tomb to be allocated for each multicast group the interface is subscribed to, which in turn leaks one struct ifmcaddr6 per nontrivial multicast group the interface is subscribed to. The following reproducer will leak at least $n objects: ip addr add ff2e::4242/32 dev eth0 autojoin sysctl -w net.ipv6.conf.eth0.disable_ipv6=1 for i in $(seq 1 $n); do ip link set up eth0; ip link set down eth0 done Joining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting the sysctl net.ipv6.conf.eth0.forwarding to 1 (=> subscribing to ff02::2) can also be used to create a nontrivial idev->mc_list, which will the leak objects with the right up-down-sequence. Based on both sources for NETDEV_DOWN events the interface IPv6 state should be considered: - not ready if the network interface is not ready OR IPv6 is disabled for it - ready if the network interface is ready AND IPv6 is enabled for it The functions ipv6_mc_up() and ipv6_down() should only be run when this state changes. Implement this by remembering when the IPv6 state is ready, and only run ipv6_mc_down() if it actually changed from ready to not ready. The other direction (not ready -> ready) already works correctly, as: - the interface notification triggered codepath for NETDEV_UP / NETDEV_CHANGE returns early if ipv6 is disabled, and - the disable_ipv6=0 triggered codepath skips fully initializing the interface as long as addrconf_link_ready(dev) returns false - calling ipv6_mc_up() repeatedly does not leak anything Fixes: 3ce62a84d53c ("ipv6: exit early in addrconf_notify() if IPv6 is disabled") Signed-off-by: Johannes Nixdorf <j.nixdorf(a)avm.de> Signed-off-by: David S.

[PATCH 4.9.y] net: sched: prevent UAF on tc_ctl_tfilter when temporarily dropping rtnl_lock

by Thadeu Lima de Souza Cascardo

When dropping the rtnl_lock for looking up for a module, the device may be removed, releasing the qdisc and class memory. Right after trying to load the module, cl_ops->put is called, leading to a potential use-after-free. Though commit e368fdb61d8e ("net: sched: use Qdisc rcu API instead of relying on rtnl lock") fixes this, it involves a lot of refactoring of the net/sched/ code, complicating its backport. This fix calls cl_ops->put before dropping rtnl_lock as it will be called either way, and zeroes it out so it won't be called again on the exit path. This has been shown to stop the following KASAN report with the reproducer: [ 256.609111] ================================================================== [ 256.609585] BUG: KASAN: use-after-free in cbq_put+0x20/0xd0 at addr ffff880021daaba0 [ 256.610078] Read of size 4 by task total_cbq/11184 [ 256.610380] CPU: 0 PID: 11184 Comm: total_cbq Not tainted 4.9.311 #78 [ 256.610778] ffff8800215875a8 ffffffff96e18735 ffff880024803080 ffff880021daaa80 [ 256.611274] ffff8800215875d0 ffffffff96334841 ffffed00043b5574 ffffed00043b5574 [ 256.611768] ffff880024803080 ffff880021587658 ffffffff96334af8 0000000000000000 [ 256.612186] Call Trace: [ 256.612344] [<ffffffff96e18735>] dump_stack+0x6d/0x8b [ 256.612632] [<ffffffff96334841>] kasan_object_err+0x21/0x70 [ 256.612973] [<ffffffff96334af8>] kasan_report.part.1+0x218/0x4f0 [ 256.613349] [<ffffffff96c5a2e0>] ? cbq_put+0x20/0xd0 [ 256.613634] [<ffffffff96333cd6>] ? kasan_unpoison_shadow+0x36/0x50 [ 256.613993] [<ffffffff96335105>] kasan_report+0x25/0x30 [ 256.614288] [<ffffffff96333701>] __asan_load4+0x61/0x80 [ 256.614580] [<ffffffff96c5a2e0>] cbq_put+0x20/0xd0 [ 256.614862] [<ffffffff96c53184>] tc_ctl_tfilter+0x4f4/0xb80 [ 256.615151] [<ffffffff96c52c90>] ? tfilter_notify+0x140/0x140 [ 256.615478] [<ffffffff960056ef>] ? do_syscall_64+0xef/0x190 [ 256.615799] [<ffffffff96e28a8e>] ? entry_SYSCALL_64_after_swapgs+0x58/0xc6 [ 256.616190] [<ffffffff96bce3f6>] ? sock_sendmsg+0x76/0x80 [ 256.616484] [<ffffffff96bce53f>] ? sock_write_iter+0x13f/0x1f0 [ 256.616833] [<ffffffff96367b02>] ? __vfs_write+0x262/0x3c0 [ 256.617152] [<ffffffff96369dc9>] ? vfs_write+0xf9/0x260 [ 256.617451] [<ffffffff9636c009>] ?

[PATCH] KVM: PPC: Book3S PR: Enable MSR_DR for switch_mmu_context()

by Alexander Graf

Commit 863771a28e27 ("powerpc/32s: Convert switch_mmu_context() to C") moved the switch_mmu_context() to C. While in principle a good idea, it meant that the function now uses the stack. The stack is not accessible from real mode though. So to keep calling the function, let's turn on MSR_DR while we call it. That way, all pointer references to the stack are handled virtually.

Re: [PATCH] mmc: rtsx: add 74 Clocks in power on flow

by Christian Löhle

Can we get 1f311c94aabdb419c28e3147bcc8ab89269f1a7e merged into the stable tree? I have some compatibility issues on Realtek chips because of the missing initialization clocks. Thanks!

During these steps the core also tries to manage the different delays that are needed according to the eMMC/SD specs. You may have a look at mmc_power_up() in drivers/mmc/core/core.c. In the rtsx case, MMC_POWER_ON and MMC_POWER_UP are treated as one single step. Moreover, it has turned out that some mmc HWs are actually controlling these delays during the initialization themselves, which makes the delays in the core superfluous. Therefore we have made the delays configurable for host drivers. For DT based platforms, we have the DT property "post-power-on-delay-ms" and for others, it's perfectly fine to update host->power_delay_ms before calling mmc_add_host(). Would it be possible to take advantage of the above "features" from the core, to avoid hard coded and superfluous delays?
