2020-07-30atm: fix atm_dev refcnt leaks in atmtcp_remove_persistentXin Xiong
atmtcp_remove_persistent() invokes atm_dev_lookup(), which returns a reference of atm_dev with increased refcount or NULL if fails. The refcount leaks issues occur in two error handling paths. If dev_data->persist is zero or PRIV(dev)->vcc isn't NULL, the function returns 0 without decreasing the refcount kept by a local variable, resulting in refcount leaks. Fix the issue by adding atm_dev_put() before returning 0 both when dev_data->persist is zero or PRIV(dev)->vcc isn't NULL.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-01-25firestream: fix memory leaksWenwen Wang
In fs_open(), 'vcc' is allocated through kmalloc() and assigned to 'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g., there is no more free channel, an error code EBUSY or ENOMEM will be returned. However, 'vcc' is not deallocated, leading to memory leaks. Note that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated in fs_close(). But, if fs_open() fails, there is no guarantee that fs_close() will be invoked. To fix this issue, deallocate 'vcc' before the error code is returned. Signed-off-by: Wenwen Wang <wenwen@cs.uga.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up.

2019-01-17atm: he: fix sign-extension overflow on large shiftColin Ian King
Shifting the 1 by exp by an int can lead to sign-extension overlow when exp is 31 since 1 is an signed int and sign-extending this result to an unsigned long long will set the upper 32 bits. Fix this by shifting an unsigned long. Detected by cppcheck: (warning) Shifting signed 32-bit value by 31 bits is undefined behaviour Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: David S.

2019-01-08cross-tree: phase out dma_zalloc_coherent()Luis Chamberlain
We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out.

There is no need for an indirection before calling the dma alloc routines now that we store a struct device in struct fore200e. Also remove the pointless GFP_ATOMIC for the sbus case, and fix the up the error handling by removing the 0 dma_addr test - some iommus can return 0 as a perfectly valid bus address.
