[Linux-stable-mirror] Patch "route: update fnhe_expires for redirect when the fnhe exists" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled route: update fnhe_expires for redirect when the fnhe exists to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: route-update-fnhe_expires-for-redirect-when-the-fnhe-exists.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Tue Dec 12 13:26:17 CET 2017 From: Xin Long <lucien.xin(a)gmail.com> Date: Fri, 17 Nov 2017 14:27:06 +0800 Subject: route: update fnhe_expires for redirect when the fnhe exists From: Xin Long <lucien.xin(a)gmail.com> [ Upstream commit e39d5246111399dbc6e11cd39fd8580191b86c47 ] Now when creating fnhe for redirect, it sets fnhe_expires for this new route cache. But when updating the exist one, it doesn't do it. It will cause this fnhe never to be expired. Paolo already noticed it before, in Jianlin's test case, it became even worse: When ip route flush cache, the old fnhe is not to be removed, but only clean it's members. When redirect comes again, this fnhe will be found and updated, but never be expired due to fnhe_expires not being set. So fix it by simply updating fnhe_expires even it's for redirect.

The effect of running the SMT code on a !SMT part is basically a more aggressive select_idle_cpu(). Removing the avg condition fixed things for him.

[Linux-stable-mirror] Patch "rds: tcp: Sequence teardown of listen and acceptor sockets to avoid races" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled rds: tcp: Sequence teardown of listen and acceptor sockets to avoid races to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: rds-tcp-sequence-teardown-of-listen-and-acceptor-sockets-to-avoid-races.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Tue Dec 12 13:26:17 CET 2017 From: Sowmini Varadhan <sowmini.varadhan(a)oracle.com> Date: Sat, 4 Mar 2017 08:57:35 -0800 Subject: rds: tcp: Sequence teardown of listen and acceptor sockets to avoid races From: Sowmini Varadhan <sowmini.varadhan(a)oracle.com> [ Upstream commit b21dd4506b71bdb9c5a20e759255cd2513ea7ebe ] Commit a93d01f5777e ("RDS: TCP: avoid bad page reference in rds_tcp_listen_data_ready") added the function rds_tcp_listen_sock_def_readable() to handle the case when a partially set-up acceptor socket drops into rds_tcp_listen_data_ready(). However, if the listen socket (rtn->rds_tcp_listen_sock) is itself going through a tear-down via rds_tcp_listen_stop(), the (*ready)() will be null and we would hit a panic of the form BUG: unable to handle kernel NULL pointer dereference at (null) IP: (null) : ? rds_tcp_listen_data_ready+0x59/0xb0 [rds_tcp] tcp_data_queue+0x39d/0x5b0 tcp_rcv_established+0x2e5/0x660 tcp_v4_do_rcv+0x122/0x220 tcp_v4_rcv+0x8b7/0x980 : In the above case, it is not fatal to encounter a NULL value for ready- we should just drop the packet and let the flush of the acceptor thread finish gracefully. In general, the tear-down sequence for listen() and accept() socket that is ensured by this commit is: rtn->rds_tcp_listen_sock = NULL; /* prevent any new accepts */ In rds_tcp_listen_stop(): serialize with, and prevent, further callbacks using lock_sock() flush rds_wq flush acceptor workq sock_release(listen socket) Signed-off-by: Sowmini Varadhan <sowmini.varadhan(a)oracle.com> Signed-off-by: David S.

[Linux-stable-mirror] Patch "powerpc/powernv/ioda2: Gracefully fail if too many TCE levels requested" has been added to the 4.9-stable tree

The existing IODA2 table allocation code aligns the minimum TCE table size to PAGE_SIZE so in the case of 64K system pages and 4K IOMMU pages, we have 64-4-12=48 bits. Since 64K page stores 8192 TCEs, i.e. needs 13 bits, the maximum number of levels is 48/13 = 3 so we physically cannot address more and EEH happens on DMA accesses. This adds a check that too many levels were requested. It is still possible to have 5 levels in the case of 4K system page size.

Alan Modra says: you need both -mbig and -mabi=elfv1 to make a powerpc64le gcc generate powerpc64 code The opposite is true for powerpc64 when generating -mlittle it requires -mabi=elfv2 to generate v2 ABI, which we were already doing. This change adds ABI annotations together with endianness for all cases, LE and BE. This fixes the case of building a BE kernel with a toolchain that is LE by default.
