[BACKPORT PATCH] mtd: nand: fix return value check for bad block status

by Abhishek Sahu

commit e9893e6fa932f42c90c4ac5849fa9aa0f0f00a34 upstream. Positive return value from read_oob() is making false BAD blocks. For some of the NAND controllers, OOB bytes will be protected with ECC and read_oob() will return number of bitflips. If there is any bitflip in ECC protected OOB bytes for BAD block status page, then that block is getting treated as BAD.

by Dan Rue

Hi Greg - Please apply bfe72442578b ("net: phy: micrel: fix crash when statistic requested for KSZ9031 phy") to 4.9.y. Since at least 4.9.95 (this was discussed during 4.9.95 release cycle), 'ethtool --phy-statistics eth0' causes a system crash on micrel systems. This is still happening, and this patch fixes the issue. Thanks! Dan

[PATCH] cifs: Fix slab-out-of-bounds in send_set_info() on SMB2 ACE setting

by Stefano Brivio

A "small" CIFS buffer is not big enough in general to hold a setacl request for SMB2, and we end up overflowing the buffer in send_set_info().

[PATCH v4 2/3] ioremap: Update pgtable free interfaces with addr

by Toshi Kani

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64. Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page() so that TLB purge can be added later in seprate patches.

[PATCH] cifs: Fix infinite loop when using hard mount option

by Paulo Alcantara

For every request we send, whether it is SMB1 or SMB2+, we attempt to reconnect tcon (cifs_reconnect_tcon or smb2_reconnect) before carrying out the request. So, while server->tcpStatus != CifsNeedReconnect, we wait for the reconnection to succeed on wait_event_interruptible_timeout(). If it returns, that means that either the condition was evaluated to true, or timeout elapsed, or it was interrupted by a signal. Since we're not handling the case where the process woke up due to a received signal (-ERESTARTSYS), the next call to wait_event_interruptible_timeout() will _always_ fail and we end up looping forever inside either cifs_reconnect_tcon() or smb2_reconnect(). Here's an example of how to trigger that: $ mount.cifs //foo/share /mnt/test -o username=foo,password=foo,vers=1.0,hard (break connection to server before executing bellow cmd) $ stat -f /mnt/test & sleep 140 [1] 2511 $ ps -aux -q 2511 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2511 0.0 0.0 12892 1008 pts/0 S 12:24 0:00 stat -f /mnt/test $ kill -9 2511 (wait for a while; process is stuck in the kernel) $ ps -aux -q 2511 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 2511 83.2 0.0 12892 1008 pts/0 R 12:24 30:01 stat -f /mnt/test By using 'hard' mount point means that cifs.ko will keep retrying indefinitely, however we must allow the process to be killed otherwise it would hang the system.

stable request: Revert "sit: reload iphdr in ipip6_rcv"

by Luca Boccassi

Hello, Please consider backporting to 4.9.y the following commit from DaveM [CC'ed]: f4eb17e1efe538d4da7d574bedb00a8dafcc26b7 ("Revert "sit: reload iphdr in ipip6_rcv"") It cherry-picks cleanly and builds fine. The original commit was introduced and reverted in v4.12-rc5, but only the original made its way into the 4.9 stable release (v4.9.94). It causes a regression: pings to v6 hosts over a SIT tunnel do not work anymore, and the following error appears in dmesg: kernel: sit: non-ECT from 0.0.0.0 with TOS=0xd This was also reported and reverted downstream by Ubuntu: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1772775 Thanks! -- Kind regards, Luca Boccassi
