[PATCH] x86/nmi: Fix some races in NMI uaccess

by Andy Lutomirski

In NMI context, we might be in the middle of context switching or in the middle of switch_mm_irqs_off(). In either case, CR3 might not match current->mm, which could cause copy_from_user_nmi() and friends to read the wrong memory. Fix it by adding a new nmi_uaccess_okay() helper and checking it in copy_from_user_nmi() and in __copy_from_user_nmi()'s callers. Cc: stable(a)vger.kernel.org Cc: Peter Zijlstra <peterz(a)infradead.org> Cc: Nadav Amit <nadav.amit(a)gmail.com> Signed-off-by: Andy Lutomirski <luto(a)kernel.org> --- The 0day bot is still chewing on this, but I've tested it a bit locally and it seems to do the right thing. I've never observed the bug it fixes, but it does appear to fix a bug unless I've missed something.

Applied "regulator: bd71837: Disable voltage monitoring for LDO3/4" to the regulator tree

by Mark Brown

The patch regulator: bd71837: Disable voltage monitoring for LDO3/4 has been applied to the regulator tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 823f18f8b860526fc099c222619a126d57d2ad8c Mon Sep 17 00:00:00 2001 From: Matti Vaittinen <matti.vaittinen(a)fi.rohmeurope.com> Date: Wed, 29 Aug 2018 15:36:10 +0300 Subject: [PATCH] regulator: bd71837: Disable voltage monitoring for LDO3/4 There is a HW quirk in BD71837.

[PATCH v3 2/2] btrfs: Ensure btrfs_trim_fs can trim the whole fs

by Qu Wenruo

[BUG] fstrim on some btrfs only trims the unallocated space, not trimming any space in existing block groups. [CAUSE] Before fstrim_range passed to btrfs_trim_fs(), it get truncated to range [0, super->total_bytes). So later btrfs_trim_fs() will only be able to trim block groups in range [0, super->total_bytes). While for btrfs, any bytenr aligned to sector size is valid, since btrfs use its logical address space, there is nothing limiting the location where we put block groups. For btrfs with routine balance, it's quite easy to relocate all block groups and bytenr of block groups will start beyond super->total_bytes. In that case, btrfs will not trim existing block groups. [FIX] Just remove the truncation in btrfs_ioctl_fitrim(), so btrfs_trim_fs() can get the unmodified range, which is normally set to [0, U64_MAX].

Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()" There is another cast from unsigned long to int which causes a bounds check to fail with specially crafted input.

reboot on wandboard fails with v4.14.67 (bisected to 2059e527a6)

by Rasmus Villemoes

We're using imx_v6_v7_defconfig on our Wandboards. After upgrading to v4.14.67, reboot no longer works (or, well, takes a very long time when the watchdog is configured). v4.14.66 works fine, the breakage bisects to 2059e527a659cf16d6bb709f1c8509f7a7623fc4 (ARM: imx_v6_v7_defconfig: Select ULPI support), and reverting that on top of v4.14.67 again works.

Applied "spi: spi-fsl-dspi: fix broken DSPI_EOQ_MODE" to the spi tree

by Mark Brown

The patch spi: spi-fsl-dspi: fix broken DSPI_EOQ_MODE has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH] option: Do not try to bind to ADB interfaces

by Romain Izard

Some modems now use the Android Debug Bridge to provide a debugging interface, and some phones can also export serial ports managed by the "option" driver. The ADB daemon running in userspace tries to use USB interfaces with bDeviceClass=0xFF, bDeviceSubClass=0x42, bDeviceProtocol=1 Prevent the option driver from binding to those interfaces, as they will not be serial ports.

[PATCH] x86/speculation/l1tf: fix off-by-one error when warning that system has too much RAM

by Vlastimil Babka

Two users have reported [1] that they have an "extremely unlikely" system with more than MAX_PA/2 memory and L1TF mitigation is not effective. In fact it's a CPU with 36bits phys limit (64GB) and 32GB memory, but due to holes in the e820 map, the main region is almost 500MB over the 32GB limit: [ 0.000000] BIOS-e820: [mem 0x0000000100000000-0x000000081effffff] usable Suggestions to use 'mem=32G' to prefer L1TF mitigation while losing the 500MB revealed, that there's an off-by-one error in the check in l1tf_select_mitigation(). l1tf_pfn_limit() returns the last usable pfn (inclusive), but it's more common and hopefully less error-prone to return the first pfn that's over limit, so this patch changes that and updates the other callers.

perf/x86/intel/uncore: propose to support IIO free-running counters in 4.14

by Jin, Yao

Hi, The upstream kernel has supported IIO free-running counters on Skylake server. As of Skylake Server, there are a number of free running counters in each IIO Box that collect counts of per-box IO clocks and per-port Input/Output x BW/Utilization. There are three types of IIO free-running counters on Skylake server: 1. IO CLOCKS counter: a clock of IIO box. 2. BANDWIDTH counters: count inbound(PCIe->CPU)/outbound(CPU->PCIe) bandwidth. 3. UTILIZATION counters: count input/output utilization. With these IIO free-running counters, we can get good observation for IIO traffic on Skylake server. For example, we can see the IIO inbound bandwidth (PCIe->CPU). root@skx /sys/devices# perf stat -a -e uncore_iio_free_running_2/bw_in_port0/ ^C Performance counter stats for 'system wide': 153.19 MiB uncore_iio_free_running_2/bw_in_port0/ 8.037701069 seconds time elapsed I propose to backport the patches which support IIO free-running counters to 4.14 stable kernel. perf/x86/intel/uncore: Introduce customized event_read() for client IMC uncore 2da331465f44f9618abe8837d1a68405d550b66e perf/x86/intel/uncore: Add new data structures for free running counters 927b2deb067b8b4753fc09c7a42092f43fc0c1f6 perf/x86/intel/uncore: Add infrastructure for free running counters 0e0162dfcd1fbe4c711ee86f24f966c318999603 perf/x86/intel/uncore: Support IIO free-running counters on SKX 0f519f0352e37e7d71bdce5559517c74a35f6e33 perf/x86/intel/uncore: Expose uncore_pmu_event*() functions 5a6c9d94e9ed7410142bc6fcb638a4db1895aa0c perf/x86/intel/uncore: Clean up client IMC uncore 9aae1780e7e81e54edfb70ba33ead5b0b48be009 Thanks Jin Yao

[PATCH v2 3/3] x86/kvm: use __decrypted attribute when declaring shared variables

by Brijesh Singh

The following commit: 368a540e0232 (x86/kvmclock: Remove memblock dependency) caused SEV guest regression. When SEV is active, we map the shared variables (wall_clock and hv_clock_boot) with C=0 to ensure that both the guest and the hypervisor is able to access the data. To map the variables we use kernel_physical_mapping_init() to split the large pages, but this routine fails to allocate a new page. Before the above commit, kvmclock initialization was called after memory allocator was available but now its called very early in the boot process. Recently we added a special .data..decrypted section to hold the shared variables. This section is mapped with C=0 very early. Use __decrypted attribute to put the wall_clock and hv_clock_boot in .data..decrypted section so that they are mapped with C=0.

[PATCH -next] spi: Fix double IDR allocation with DT aliases

[PATCH 1/2] x86/mm: add .data..decrypted section to hold shared variables

by Brijesh Singh

kvmclock defines few static variables which are shared with hypervisor during the kvmclock initialization. When SEV is active, memory is encrypted with a guest-specific key, and if guest OS wants to share the memory region with hypervisor then it must clear the C-bit before sharing it. The '__decrypted' can be used to define a shared variables; the variables will be put in the .data.decryption section. This section is mapped with C=0 early in the boot, we also ensure that the initialized values are updated to match with C=0 (i.e peform an in-place decryption).

[PATCH v2] mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MB

by Liu Xiang

If the size of spi-nor flash is larger than 16MB, the read_opcode is set to SPINOR_OP_READ_1_1_4_4B, and fsl_qspi_get_seqid() will return -EINVAL when cmd is SPINOR_OP_READ_1_1_4_4B.

[PATCH] tty: serial: lpuart: avoid leaking struct tty_struct

by Stefan Agner

The function tty_port_tty_get() gets a reference to the tty. Since the code is not using tty_port_tty_set(), the reference is kept even after closing the tty. Avoid using tty_port_tty_get() by directly access the tty instance. Since lpuart_start_rx_dma() is called from the .startup() and .set_termios() callback, it is safe to assume the tty instance is valid. Cc: stable(a)vger.kernel.org # v4.9+ Fixes: 5887ad43ee02 ("tty: serial: fsl_lpuart: Use cyclic DMA for Rx") Signed-off-by: Stefan Agner <stefan(a)agner.ch> --- This fixes a memory leak observable when opening/closing the tty in a loop.

[PATCH] xprtrdma: Fix disconnect regression

by Chuck Lever

I found that injecting disconnects with v4.18-rc resulted in random failures of the multi-threaded git regression test. The root cause appears to be that, after a reconnect, the RPC/RDMA transport is waking pending RPCs before the transport has posted enough Receive buffers to receive the Replies. If a Reply arrives before enough Receive buffers are posted, the connection is dropped. A few connection drops happen in quick succession as the client and server struggle to regain credit synchronization. This regression was introduced with commit 7c8d9e7c8863 ("xprtrdma: Move Receive posting to Receive handler"). The client is supposed to post a single Receive when a connection is established because it's not supposed to send more than one RPC Call before it gets a fresh credit grant in the first RPC Reply [RFC 8166, Section 3.3.3]. Unfortunately there appears to be a longstanding bug in the Linux client's credit accounting mechanism. On connect, it simply dumps all pending RPC Calls onto the new connection. It's possible it has done this ever since the RPC/RDMA transport was added to the kernel ten years ago. Servers have so far been tolerant of this bad behavior. Currently no server implementation ever changes its credit grant over reconnects, and servers always repost enough Receives before connections are fully established. The Linux client implementation used to post a Receive before each of these Calls. This has covered up the flooding send behavior. I could try to correct this old bug so that the client sends exactly one RPC Call and waits for a Reply. Since we are so close to the next merge window, I'm going to instead provide a simple patch to post enough Receives before a reconnect completes (based on the number of credits granted to the previous connection). The spurious disconnects will be gone, but the client will still send multiple RPC Calls immediately after a reconnect. Addressing the latter problem will wait for a merge window because a) I expect it to be a large change requiring lots of testing, and b) obviously the Linux client has interoperated successfully since day zero while still being broken.

[char-misc for 4.9 2/2] mei: bus: need to unlink client before freeing

In case a client fails to connect in mei_cldev_enable(), the caller won't call the mei_cldev_disable leaving the client in a linked stated. Upon driver unload the client structure will be freed in mei_cl_bus_dev_release(), leaving a stale pointer on a fail_list.

[PATCH] ext4: avoid buffer overrun when deleting inline directories

by Theodore Ts'o

A specially crafted file system can trick empty_inline_dir() into reading beyond the bounds of inline directory. Fix this by using the size of the inline directory instead of dir->i_size. Also clean up error reporting in __ext4_check_dir_entry so that the message is clearer and more understandable --- and avoids a potential division by zero trap if the size passed in is zero. (I'm not sure why we coded it that way in the first place; printing offset % size is actually more confusing and less useful.) https://bugzilla.kernel.org/show_bug.cgi?id=200933 Signed-off-by: Theodore Ts'o <tytso(a)mit.edu> Reported-by: Wen Xu <wen.xu(a)gatech.edu> Cc: stable(a)vger.kernel.org --- fs/ext4/dir.c | 20 +++++++++----------- fs/ext4/inline.c | 4 +++- 2 files changed, 12 insertions(+), 12 deletions(-) diff --git a/fs/ext4/dir.c b/fs/ext4/dir.c index e2902d394f1b..f93f9881ec18 100644 --- a/fs/ext4/dir.c +++ b/fs/ext4/dir.c @@ -76,7 +76,7 @@ int __ext4_check_dir_entry(const char *function, unsigned int line, else if (unlikely(rlen < EXT4_DIR_REC_LEN(de->name_len))) error_msg = "rec_len is too small for name_len"; else if (unlikely(((char *) de - buf) + rlen > size)) - error_msg = "directory entry across range"; + error_msg = "directory entry overrun"; else if (unlikely(le32_to_cpu(de->inode) > le32_to_cpu(EXT4_SB(dir->i_sb)->s_es->s_inodes_count))) error_msg = "inode out of bounds"; @@ -85,18 +85,16 @@ int __ext4_check_dir_entry(const char *function, unsigned int line, if (filp) ext4_error_file(filp, function, line, bh->b_blocknr, - "bad entry in directory: %s - offset=%u(%u), " - "inode=%u, rec_len=%d, name_len=%d", - error_msg, (unsigned) (offset % size), - offset, le32_to_cpu(de->inode), - rlen, de->name_len); + "bad entry in directory: %s - offset=%u, " + "inode=%u, rec_len=%d, name_len=%d, size=%d", + error_msg, offset, le32_to_cpu(de->inode), + rlen, de->name_len, size); else ext4_error_inode(dir, function, line, bh->b_blocknr, - "bad entry in directory: %s - offset=%u(%u), " - "inode=%u, rec_len=%d, name_len=%d", - error_msg, (unsigned) (offset % size), - offset, le32_to_cpu(de->inode), - rlen, de->name_len); + "bad entry in directory: %s - offset=%u, " + "inode=%u, rec_len=%d, name_len=%d, size=%d", + error_msg, offset, le32_to_cpu(de->inode), + rlen, de->name_len, size); return 1; } diff --git a/fs/ext4/inline.c b/fs/ext4/inline.c index 3543fe80a3c4..7b4736022761 100644 --- a/fs/ext4/inline.c +++ b/fs/ext4/inline.c @@ -1753,6 +1753,7 @@ bool empty_inline_dir(struct inode *dir, int *has_inline_data) { int err, inline_size; struct ext4_iloc iloc; + size_t inline_len; void *inline_pos; unsigned int offset; struct ext4_dir_entry_2 *de; @@ -1780,8 +1781,9 @@ bool empty_inline_dir(struct inode *dir, int *has_inline_data) goto out; } + inline_len = ext4_get_inline_size(dir); offset = EXT4_INLINE_DOTDOT_SIZE; - while (offset < dir->i_size) { + while (offset < inline_len) { de = ext4_get_inline_entry(dir, &iloc, offset, &inline_pos, &inline_size); if (ext4_check_dir_entry(dir, NULL, de, -- 2.18.0.rc0

[PATCH 2/2] x86/kvm: use __decrypted attribute when declaring shared variables

by Brijesh Singh

The following commit: 368a540e0232 (x86/kvmclock: Remove memblock dependency) caused SEV guest regression. When SEV is active, we map the shared variables (wall_clock and hv_clock_boot) with C=0 to ensure that both the guest and the hypervisor is able to access the data. To map the variables we use kernel_physical_mapping_init() to split the large pages, but this routine fails to allocate a new page. Before the above commit, kvmclock initialization was called after memory allocator was available but now its called very early in the boot process. Recently we added a special .data..decrypted section to hold the shared variables. This section is mapped with C=0 very early. Use __decrypted attribute to put the wall_clock and hv_clock_boot in .data..decrypted section so that they are mapped with C=0.

Use the new of_get_compatible_child() helper to lookup the usb sibling node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node).

Backport e666d4e9ceec crypto: vmx - Use skcipher for ctr fallback

by Petr Vorel

Hi, I wonder, it it makes sense to backport commit e666d4e9ceec crypto: vmx - Use skcipher for ctr fallback to v 4.14 stable kernel. I'm using it in 4.12+. These commits (somehow similar) has been backported to 4.10.2: 5839f555fa57 crypto: vmx - Use skcipher for xts fallback c96d0a1c47ab crypto: vmx - Use skcipher for cbc fallback Kind regards, Petr

[PATCH 1/3] drm/i915: Handle incomplete Z_FINISH for compressed error states

by Chris Wilson

The final call to zlib_deflate(Z_FINISH) may require more output space to be allocated and so needs to re-invoked. Failure to do so in the current code leads to incomplete zlib streams (albeit intact due to the use of Z_SYNC_FLUSH) resulting in the occasional short object capture.

Hi Greg, This patch is not marked for 4.4-stable, but it's already in 4.9 and 4.14 stable. This is a trivial rename patch, but the naming would be more logical and makes backports easier. Please consider to apply this patch to 4.4-stable. -- SZ Lin (林上智)

[PATCH v2] crypto: vmx - Fix sleep-in-atomic bugs

by Ondrej Mosnacek

This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX implementations. The problem is that the blkcipher_* functions should not be called in atomic context. The bugs can be reproduced via the AF_ALG interface by trying to encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then trigger BUG in crypto_yield(): [ 891.863680] BUG: sleeping function called from invalid context at include/crypto/algapi.h:424 [ 891.864622] in_atomic(): 1, irqs_disabled(): 0, pid: 12347, name: kcapi-enc [ 891.864739] 1 lock held by kcapi-enc/12347: [ 891.864811] #0: 00000000f5d42c46 (sk_lock-AF_ALG){+.+.}, at: skcipher_recvmsg+0x50/0x530 [ 891.865076] CPU: 5 PID: 12347 Comm: kcapi-enc Not tainted 4.19.0-0.rc0.git3.1.fc30.ppc64le #1 [ 891.865251] Call Trace: [ 891.865340] [c0000003387578c0] [c000000000d67ea4] dump_stack+0xe8/0x164 (unreliable) [ 891.865511] [c000000338757910] [c000000000172a58] ___might_sleep+0x2f8/0x310 [ 891.865679] [c000000338757990] [c0000000006bff74] blkcipher_walk_done+0x374/0x4a0 [ 891.865825] [c0000003387579e0] [d000000007e73e70] p8_aes_cbc_encrypt+0x1c8/0x260 [vmx_crypto] [ 891.865993] [c000000338757ad0] [c0000000006c0ee0] skcipher_encrypt_blkcipher+0x60/0x80 [ 891.866128] [c000000338757b10] [c0000000006ec504] skcipher_recvmsg+0x424/0x530 [ 891.866283] [c000000338757bd0] [c000000000b00654] sock_recvmsg+0x74/0xa0 [ 891.866403] [c000000338757c10] [c000000000b00f64] ___sys_recvmsg+0xf4/0x2f0 [ 891.866515] [c000000338757d90] [c000000000b02bb8] __sys_recvmsg+0x68/0xe0 [ 891.866631] [c000000338757e30] [c00000000000bbe4] system_call+0x5c/0x70 Fixes: 8c755ace357c ("crypto: vmx - Adding CBC routines for VMX module") Fixes: c07f5d3da643 ("crypto: vmx - Adding support for XTS") Cc: stable(a)vger.kernel.org Signed-off-by: Ondrej Mosnacek <omosnace(a)redhat.com> --- Still untested, please test and review if possible.

When scanning for movable pages, filter out Hugetlb pages if hugepage migration is not supported.

How to report kernel panic in 4.4.x

by Matthias B.

Hallo, 4.4.147 is the last kernel of the 4.4.x series that boots for me. All subsequent versions panic on boot. How do I report this bug? If I'm supposed to use https://bugzilla.kernel.org/ I don't know what to fill into the fields. I don't even know if the longterm kernel falls under "Mainline" or some other tree. MSB -- Fun chemistry experiments: Sodium chloride doubles its volume when combined with an equal amount of table salt.

kernel-doc patches for 4.18

by Nathan Chancellor

Hi Greg, Arch Linux recently enabled building the kernel documentation in their PKGBUILD, which turned my normally peaceful build into a spamfest of unescaped braces warnings from Perl. These are fixed upstream with the following two patches: 701b3a3c0ac4 ("PATCH scripts/kernel-doc") 673bb2dfc364 ("scripts/kernel-doc: Escape all literal braces in regexes") Could they please be applied to 4.18? They should be clean cherry-picks. Thanks! Nathan

Current LTS and their EOL

by Rodrigo Vivi

Hi Greg, Ben, and all Is https://www.kernel.org/category/releases.html updated in terms of EOL? Some news out of Linaro conference [2] generated a lot of doubts and questions around. Specially because on the way it was stated by the news 3.16 wouldn't be active anymore. So I'm not sure about the news, but I'd like confirmation from you about expected EOL. [2] https://itsfoss.com/linux-lts-kernel-six-years/ Thanks in advance, Rodrigo.

[PATCH v2] avoid race condition between start_xmit and cm_rep_handler

by Aaron Knister

Inside of start_xmit() the call to check if the connection is up and the queueing of the packets for later transmission is not atomic which leaves a window where cm_rep_handler can run, set the connection up, dequeue pending packets and leave the subsequently queued packets by start_xmit() sitting on neigh->queue until they're dropped when the connection is torn down. This only applies to connected mode. These dropped packets can really upset TCP, for example, and cause multi-minute delays in transmission for open connections. Here's the code in start_xmit where we check to see if the connection is up: if (ipoib_cm_get(neigh)) { if (ipoib_cm_up(neigh)) { ipoib_cm_send(dev, skb, ipoib_cm_get(neigh)); goto unref; } } The race occurs if cm_rep_handler execution occurs after the above connection check (specifically if it gets to the point where it acquires priv->lock to dequeue pending skb's) but before the below code snippet in start_xmit where packets are queued. if (skb_queue_len(&neigh->queue) < IPOIB_MAX_PATH_REC_QUEUE) { push_pseudo_header(skb, phdr->hwaddr); spin_lock_irqsave(&priv->lock, flags); __skb_queue_tail(&neigh->queue, skb); spin_unlock_irqrestore(&priv->lock, flags); } else { ++dev->stats.tx_dropped; dev_kfree_skb_any(skb); } The patch re-checks ipoib_cm_up with priv->lock held to avoid this race condition. Since odds are the conn should be up most of the time (and thus the connection *not* down most of the time) we don't hold the lock for the first check attempt to avoid a slowdown from unecessary locking for the majority of the packets transmitted during the connection's life.

I'm announcing the release of the 4.17.19 kernel. Note, this is the LAST 4.17.y kernel to be released, it is now end-of-life. Pleas move to 4.18.y at this time. All users of the 4.17 kernel series must upgrade. The updated 4.17.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.17.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 8 -

[PATCH 4/9] mmc: meson-mx-sdio: fix OF child-node lookup

Use the new of_get_compatible_child() helper to lookup the slot child node instead of using of_find_compatible_node(), which searches the entire tree and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the node of the device being probed). While at it, also fix up the related slot-node reference leak.

[PATCH] lpfc: Correct MDS diag and nvmet configuration

by James Smart

A recent change added some MDS processing in the lpfc_drain_txq routine that relies on the fcp_wq being allocated. For nvmet operation the fcp_wq is not allocated because it can only be an nvme-target. When the original MDS support was added LS_MDS_LOOPBACK was defined wrong, (0x16) it should have been 0x10 (decimal value used for hex setting). This incorrect value allowed MDS_LOOPBACK to be set simultaneously with LS_NPIV_FAB_SUPPORTED, causing the driver to crash when it accesses the non-existent fcp_wq. Correct the bad value setting for LS_MDS_LOOPBACK. Fixes: ae9e28f36a6c ("lpfc: Add MDS Diagnostic support.")

+ mm-migration-fix-migration-of-huge-pmd-shared-pages.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: migration: fix migration of huge PMD shared pages has been added to the -mm tree. Its filename is mm-migration-fix-migration-of-huge-pmd-shared-pages.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-migration-fix-migration-of-huge… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-migration-fix-migration-of-huge… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: mm: migration: fix migration of huge PMD shared pages The page migration code employs try_to_unmap() to try and unmap the source page. This is accomplished by using rmap_walk to find all vmas where the page is mapped. This search stops when page mapcount is zero. For shared PMD huge pages, the page map count is always 1 no matter the number of mappings. Shared mappings are tracked via the reference count of the PMD page. Therefore, try_to_unmap stops prematurely and does not completely unmap all mappings of the source page. This problem can result is data corruption as writes to the original source page can happen after contents of the page are copied to the target page. Hence, data is lost. This problem was originally seen as DB corruption of shared global areas after a huge page was soft offlined due to ECC memory errors. DB developers noticed they could reproduce the issue by (hotplug) offlining memory used to back huge pages. A simple testcase can reproduce the problem by creating a shared PMD mapping (note that this must be at least PUD_SIZE in size and PUD_SIZE aligned (1GB on x86)), and using migrate_pages() to migrate process pages between nodes while continually writing to the huge pages being migrated. To fix, have the try_to_unmap_one routine check for huge PMD sharing by calling huge_pmd_unshare for hugetlbfs huge pages. If it is a shared mapping it will be 'unshared' which removes the page table entry and drops the reference on the PMD page. After this, flush caches and TLB. mmu notifiers are called before locking page tables, but we can not be sure of PMD sharing until page tables are locked. Therefore, check for the possibility of PMD sharing before locking so that notifiers can prepare for the worst possible case.

[merged] reiserfs-fix-broken-xattr-handling-heap-corruption-bad-retval.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: reiserfs: fix broken xattr handling (heap corruption, bad retval) has been removed from the -mm tree. Its filename was reiserfs-fix-broken-xattr-handling-heap-corruption-bad-retval.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Jann Horn <jannh(a)google.com> Subject: reiserfs: fix broken xattr handling (heap corruption, bad retval) This fixes the following issues: - When a buffer size is supplied to reiserfs_listxattr() such that each individual name fits, but the concatenation of all names doesn't fit, reiserfs_listxattr() overflows the supplied buffer. This leads to a kernel heap overflow (verified using KASAN) followed by an out-of-bounds usercopy and is therefore a security bug. - When a buffer size is supplied to reiserfs_listxattr() such that a name doesn't fit, -ERANGE should be returned. But reiserfs instead just truncates the list of names; I have verified that if the only xattr on a file has a longer name than the supplied buffer length, listxattr() incorrectly returns zero. With my patch applied, -ERANGE is returned in both cases and the memory corruption doesn't happen anymore. Credit for making me clean this code up a bit goes to Al Viro, who pointed out that the ->actor calling convention is suboptimal and should be changed.

[merged] zram-fix-bug-storing-backing_dev.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: drivers/block/zram/zram_drv.c: fix bug storing backing_dev has been removed from the -mm tree. Its filename was zram-fix-bug-storing-backing_dev.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Peter Kalauskas <peskal(a)google.com> Subject: drivers/block/zram/zram_drv.c: fix bug storing backing_dev The call to strlcpy in backing_dev_store is incorrect. It should take the size of the destination buffer instead of the size of the source buffer. Additionally, ignore the newline character (\n) when reading the new file_name buffer. This makes it possible to set the backing_dev as follows: echo /dev/sdX > /sys/block/zram0/backing_dev The reason it worked before was the fact that strlcpy() copies 'len - 1' bytes, which is strlen(buf) - 1 in our case, so it accidentally didn't copy the trailing new line symbol. Which also means that "echo -n /dev/sdX" most likely was broken.

[PATCH v3 1/2] mm: migration: fix migration of huge PMD shared pages

by Mike Kravetz

The page migration code employs try_to_unmap() to try and unmap the source page. This is accomplished by using rmap_walk to find all vmas where the page is mapped. This search stops when page mapcount is zero. For shared PMD huge pages, the page map count is always 1 no matter the number of mappings. Shared mappings are tracked via the reference count of the PMD page. Therefore, try_to_unmap stops prematurely and does not completely unmap all mappings of the source page. This problem can result is data corruption as writes to the original source page can happen after contents of the page are copied to the target page. Hence, data is lost. This problem was originally seen as DB corruption of shared global areas after a huge page was soft offlined due to ECC memory errors. DB developers noticed they could reproduce the issue by (hotplug) offlining memory used to back huge pages. A simple testcase can reproduce the problem by creating a shared PMD mapping (note that this must be at least PUD_SIZE in size and PUD_SIZE aligned (1GB on x86)), and using migrate_pages() to migrate process pages between nodes while continually writing to the huge pages being migrated. To fix, have the try_to_unmap_one routine check for huge PMD sharing by calling huge_pmd_unshare for hugetlbfs huge pages. If it is a shared mapping it will be 'unshared' which removes the page table entry and drops the reference on the PMD page. After this, flush caches and TLB. mmu notifiers are called before locking page tables, but we can not be sure of PMD sharing until page tables are locked. Therefore, check for the possibility of PMD sharing before locking so that notifiers can prepare for the worst possible case.

please revert commit ce8556cca6 "kbuild: verify that $DEPMOD is installed" introduced in v4.18.4.

by H. Nikolaus Schaller

This patch requires that /sbin/depmod is installed and installable on the build host. But not all build hosts for cross compiling Linux are Linux systems and are able to provide a working port of depmod, especially at the file patch /sbin/depmod. I use, for example, a Darwin system to cross compile Linux and I run depmod -a on the embedded system once, after installing a new Linux kernel there. I have no problem with seeing a warning, but aborting the build process is IMHO a bad idea since the previous behaviour didn't harm many people as far as I see. Probably 99% of people compiling Linux kernels do that on Linux and 99% of those have depmod installed for optimal operation of their build host. So IMHO printing the warning is good enough.

[PATCH] powerpc/nohash: fix pte_access_permitted()

by Christophe Leroy

Commit 5769beaf180a8 ("powerpc/mm: Add proper pte access check helper for other platforms") replaced generic pte_access_permitted() by an arch specific one. The generic one is defined as (pte_present(pte) && (!(write) || pte_write(pte))) The arch specific one is open coded checking that _PAGE_USER and _PAGE_WRITE (_PAGE_RW) flags are set, but lacking to check that _PAGE_RO and _PAGE_PRIVILEGED are unset, leading to a useless test on targets like the 8xx which defines _PAGE_RW and _PAGE_USER as 0. Commit 5fa5b16be5b31 ("powerpc/mm/hugetlb: Use pte_access_permitted for hugetlb access check") replaced some tests performed with pte helpers by a call to pte_access_permitted(), leading to the same issue. This patch rewrites powerpc/nohash pte_access_permitted() using pte helpers.
