[PATCH] perf/core: Fix race in the perf_mmap_close() function
by Yang Yingliang 16 Oct '20

16 Oct '20

From: Jiri Olsa <jolsa(a)redhat.com> mainline inclusion from mainline-v5.10 commit f91072ed1b7283b13ca57fcfbece5a3b92726143 category: bugfix bugzilla: NA CVE: CVE-2020-14351 -------------------------------- There's a possible race in perf_mmap_close() when checking ring buffer's mmap_count refcount value. The problem is that the mmap_count check is not atomic because we call atomic_dec() and atomic_read() separately. perf_mmap_close: ... atomic_dec(&rb->mmap_count); ... if (atomic_read(&rb->mmap_count)) goto out_put; <ring buffer detach> free_uid out_put: ring_buffer_put(rb); /* could be last */ The race can happen when we have two (or more) events sharing same ring buffer and they go through atomic_dec() and then they both see 0 as refcount value later in atomic_read(). Then both will go on and execute code which is meant to be run just once. The code that detaches ring buffer is probably fine to be executed more than once, but the problem is in calling free_uid(), which will later on demonstrate in related crashes and refcount warnings, like: refcount_t: addition on 0; use-after-free. ... RIP: 0010:refcount_warn_saturate+0x6d/0xf ...

[PATCH] geneve: add transport ports in route lookup for geneve
by Yang Yingliang 15 Oct '20

15 Oct '20

From: Mark Gray <mark.d.gray(a)redhat.com> stable inclusion from linux-4.19.148 commit c797110d97c48054d1491251fd713900ff51615c CVE: CVE-2020-25645 -------------------------------- [ Upstream commit 34beb21594519ce64a55a498c2fe7d567bc1ca20 ] This patch adds transport ports information for route lookup so that IPsec can select Geneve tunnel traffic to do encryption. This is needed for OVS/OVN IPsec with encrypted Geneve tunnels. This can be tested by configuring a host-host VPN using an IKE daemon and specifying port numbers. For example, for an Openswan-type configuration, the following parameters should be configured on both hosts and IPsec set up as-per normal: $ cat /etc/ipsec.conf conn in ... left=$IP1 right=$IP2 ... leftprotoport=udp/6081 rightprotoport=udp ... conn out ... left=$IP1 right=$IP2 ... leftprotoport=udp rightprotoport=udp/6081 ... The tunnel can then be setup using "ip" on both hosts (but changing the relevant IP addresses): $ ip link add tun type geneve id 1000 remote $IP2 $ ip addr add 192.168.0.1/24 dev tun $ ip link set tun up This can then be tested by pinging from $IP1: $ ping 192.168.0.2 Without this patch the traffic is unencrypted on the wire.

[PATCH 01/11] xfs: Fix tail rounding in xfs_alloc_file_space()
by Yang Yingliang 15 Oct '20

15 Oct '20

From: Max Reitz <mreitz(a)redhat.com> mainline inclusion from mainline-v5.4-rc3 commit e093c4be760ebf46c131ae0dd6138865a22f46fa category: bugfix bugzilla: NA CVE: NA --------------------------- To ensure that all blocks touched by the range [offset, offset + count) are allocated, we need to calculate the block count from the difference of the range end (rounded up) and the range start (rounded down). Before this patch, we just round up the byte count, which may lead to unaligned ranges not being fully allocated: $ touch test_file $ block_size=$(stat -fc '%S' test_file) $ fallocate -o $((block_size / 2)) -l $block_size test_file $ xfs_bmap test_file test_file: 0: [0..7]: 1396264..1396271 1: [8..15]: hole There should not be a hole there. Instead, the first two blocks should be fully allocated. With this patch applied, the result is something like this: $ touch test_file $ block_size=$(stat -fc '%S' test_file) $ fallocate -o $((block_size / 2)) -l $block_size test_file $ xfs_bmap test_file test_file: 0: [0..15]: 11024..11039 Signed-off-by: Max Reitz <mreitz(a)redhat.com> Reviewed-by: Carlos Maiolino <cmaiolino(a)redhat.com> Reviewed-by: Christoph Hellwig <hch(a)lst.de> Reviewed-by: Darrick J.

[PATCH 1/6] blk-mq: insert passthrough request into hctx->dispatch directly
by Yang Yingliang 13 Oct '20

13 Oct '20

From: Ming Lei <ming.lei(a)redhat.com> mainline inclusion from mainline-5.6-rc4 commit 01e99aeca3979600302913cef3f89076786f32c8 category: bugfix bugzilla: 42777 CVE: NA --------------------------- For some reason, device may be in one situation which can't handle FS request, so STS_RESOURCE is always returned and the FS request will be added to hctx->dispatch. However passthrough request may be required at that time for fixing the problem. If passthrough request is added to scheduler queue, there isn't any chance for blk-mq to dispatch it given we prioritize requests in hctx->dispatch. Then the FS IO request may never be completed, and IO hang is caused. So passthrough request has to be added to hctx->dispatch directly for fixing the IO hang. Fix this issue by inserting passthrough request into hctx->dispatch directly together withing adding FS request to the tail of hctx->dispatch in blk_mq_dispatch_rq_list(). Actually we add FS request to tail of hctx->dispatch at default, see blk_mq_request_bypass_insert(). Then it becomes consistent with original legacy IO request path, in which passthrough request is always added to q->queue_head.
