commit a6ab1e81 upstream. sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer set. In this case it aborts the queuing of the upcall. However it has already taken a new counted reference on "h" and doesn't "put" it, even though it frees the data structure holding the reference.

commit 6b87b70c upstream. Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections? Signed-off-by:

commit 33b96d2c upstream. Currently we have an incorrect behaviour when multiple devices are present under the weim node. For example: &weim { ... status = "okay"; sram@0,0 { ... status = "okay"; }; mram@0,0 { ... status = "disabled"; }; }; In this case only the 'sram' device should be probed and not 'mram'. However what happens currently is that the status variable is ignored, causing the 'sram' device to be disabled and 'mram' to be enabled. Change the weim_parse_dt() function to use for_each_available_child_of_node()so that the devices marked with 'status = disabled' are not probed. Suggested-by:

commit 01127848 upstream. When doing delayed allocation, update of on-disk inode size is postponed until IO submission time. However hole punch or zero range fallocate calls can end up discarding the tail page cache page and thus on-disk inode size would never be properly updated. Make sure the on-disk inode size is updated before truncating page cache. Signed-off-by:

commit 32ebffd3 upstream. Current code implementing FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_INSERT_RANGE is prone to races with buffered writes and page faults. If buffered write or write via mmap manages to squeeze between filemap_write_and_wait_range() and truncate_pagecache() in the fallocate implementations, the written data is simply discarded by truncate_pagecache() although it should have been shifted. Fix the problem by moving filemap_write_and_wait_range() call inside i_mutex and i_mmap_sem. That way we are protected against races with both buffered writes and page faults. Signed-off-by:

commit 17048e8a upstream. Currently ext4_alloc_file_blocks() was handling protection against unlocked DIO. However we now need to sometimes call it under i_mmap_sem and sometimes not and DIO protection ranks above it (although strictly speaking this cannot currently create any deadlocks). Also ext4_zero_range() was actually getting & releasing unlocked DIO protection twice in some cases. Luckily it didn't introduce any real bug but it was a land mine waiting to be stepped on. So move DIO protection out from ext4_alloc_file_blocks() into the two callsites. Signed-off-by:

commit ea3d7209 upstream. Currently, page faults and hole punching are completely unsynchronized. This can result in page fault faulting in a page into a range that we are punching after truncate_pagecache_range() has been called and thus we can end up with a page mapped to disk blocks that will be shortly freed. Filesystem corruption will shortly follow. Note that the same race is avoided for truncate by checking page fault offset against i_size but there isn't similar mechanism available for punching holes. Fix the problem by creating new rw semaphore i_mmap_sem in inode and grab it for writing over truncate, hole punching, and other functions removing blocks from extent tree and for read over page faults. We cannot easily use i_data_sem for this since that ranks below transaction start and we need something ranking above it so that it can be held over the whole truncate / hole punching operation. Also remove various workarounds we had in the code to reduce race window when page fault could have created pages with stale mapping information. Signed-off-by:

commit 3b5394a3 upstream. This patch remove the micron_quad_enable() function which force the Quad SPI mode. However, once this mode is enabled, the Micron memory expect ALL commands to use the SPI 4-4-4 protocol. Hence a failure does occur when calling spi_nor_wait_till_ready() right after the update of the Enhanced Volatile Configuration Register (EVCR) in the micron_quad_enable() as the SPI controller driver is not aware about the protocol change. Since there is almost no performance increase using Fast Read 4-4-4 commands instead of Fast Read 1-1-4 commands, we rather keep on using the Extended SPI mode than enabling the Quad SPI mode. Let's take the example of the pretty standard use of 8 dummy cycles during Fast Read operations on 64KB erase sectors: Fast Read 1-1-4 requires 8 cycles for the command, then 24 cycles for the 3byte address followed by 8 dummy clock cycles and finally 65536*2 cycles for the read data; so 131112 clock cycles. On the other hand the Fast Read 4-4-4 would require 2 cycles for the command, then 6 cycles for the 3byte address followed by 8 dummy clock cycles and finally 65536*2 cycles for the read data. So 131088 clock cycles. The theorical bandwidth increase is 0.0%. Now using Fast Read operations on 512byte pages: Fast Read 1-1-4 needs 8+24+8+(512*2) = 1064 clock cycles whereas Fast Read 4-4-4 would requires 2+6+8+(512*2) = 1040 clock cycles. Hence the theorical bandwidth increase is 2.3%. Consecutive reads for non sequential pages is not a relevant use case so The Quad SPI mode is not worth it. mtd_speedtest seems to confirm these figures. Signed-off-by:

commit ff1cab37 upstream. The BSP team noticed that there is spin/mutex lock issue on sh-sci when CPUFREQ is used. The issue is that the notifier function may call mutex_lock() while the spinlock is held, which can lead to a BUG(). This may happen if CPUFREQ is changed while another CPU calls clk_get_rate(). Taking the spinlock was added to the notifier function in commit e552de24 ("sh-sci: add platform device private data"), to protect the list of serial ports against modification during traversal. At that time the Common Clock Framework didn't exist yet, and clk_get_rate() just returned clk->rate without taking a mutex. Note that since commit d535a230 ("serial: sh-sci: Require a device per port mapping."), there's no longer a list of serial ports to traverse, and taking the spinlock became superfluous. To fix the issue, just remove the cpufreq notifier: 1. The notifier doesn't work correctly: all it does is update stored clock rates; it does not update the divider in the hardware. The divider will only be updated when calling sci_set_termios(). I believe this was broken back in 2004, when the old drivers/char/sh-sci.c driver (where the notifier did update the divider) was replaced by drivers/serial/sh-sci.c (where the notifier just updated port->uartclk). Cfr. full-history-linux commits 6f8deaef2e9675d9 ("[PATCH] sh: port sh-sci driver to the new API") and 3f73fe878dc9210a ("[PATCH] Remove old sh-sci driver"). 2. On modern SoCs, the sh-sci parent clock rate is no longer related to the CPU clock rate anyway, so using a cpufreq notifier is futile. Signed-off-by:

commit 5e1021f2 upstream. ext4_reserve_inode_write() in ext4_mark_inode_dirty() could fail on error (e.g. EIO) and iloc.bh can be NULL in this case. But the error is ignored in the following "if" condition and ext4_expand_extra_isize() might be called with NULL iloc.bh set, which triggers NULL pointer dereference. This is uncovered by commit 8b4953e1 ("ext4: reserve code points for the project quota feature"), which enlarges the ext4_inode size, and run the following script on new kernel but with old mke2fs: #/bin/bash mnt=/mnt/ext4 devname=ext4-error dev=/dev/mapper/$devname fsimg=/home/fs.img trap cleanup 0 1 2 3 9 15 cleanup() { umount $mnt >/dev/null 2>&1 dmsetup remove $devname losetup -d $backend_dev rm -f $fsimg exit 0 } rm -f $fsimg fallocate -l 1g $fsimg backend_dev=`losetup -f --show $fsimg` devsize=`blockdev --getsz $backend_dev` good_tab="0 $devsize linear $backend_dev 0" error_tab="0 $devsize error $backend_dev 0" dmsetup create $devname --table "$good_tab" mkfs -t ext4 $dev mount -t ext4 -o errors=continue,strictatime $dev $mnt dmsetup load $devname --table "$error_tab" && dmsetup resume $devname echo 3 > /proc/sys/vm/drop_caches ls -l $mnt exit 0 [ Patch changed to simplify the function a tiny bit. -- Ted ] Signed-off-by:

This change incorrectly used the "slave_links" list to determine if the subdomain is a master to another subdomain, where it should have been using the "master_links" list instead. The "slave_links" list will never be empty for a subdomain and so a subdomain can never be removed. Fix this by testing if the "master_links" list is empty instead.

This didn't go well with the regulator framework, as on few calls the min voltage was set to target and max was set to 0 and so resulted in a kernel crash like below: kernel BUG at ../drivers/regulator/core.c:216!

commit 7b64dbf8 upstream. Signed integer overflow is undefined. Also I added a check for "(offset < 0)" in scif_unregister() because that makes it match the other conditions and because I didn't want to subtract a negative.

commit 50e6315d upstream. Commit 985087db 'misc: add support for bmp18x chips to the bmp085 driver' changed the BMP085 config symbol to a boolean. I see no reason why the shared code cannot be built as a module, so change it back to tristate.
