[PATCH openEuler-1.0-LTS] tcp: add sanity checks to rx zerocopy
by Ziyang Xuan 24 Mar '24

24 Mar '24

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v6.8-rc3 commit 577e4432f3ac810049cb7e6b71f4d96ec7c6e894 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JO6 CVE: CVE-2024-26640 -------------------------------- 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 Signed-off-by: David S.
