2020-06-26scripts/kernel-doc: parse __ETHTOOL_DECLARE_LINK_MODE_MASKMauro Carvalho Chehab1-0/+2
The __ETHTOOL_DECLARE_LINK_MODE_MASK macro is a variant of DECLARE_BITMAP(), used by phylink.h. As we have already a parser for DECLARE_BITMAP(), let's add one for this macro, in order to avoid such warnings: ./include/linux/phylink.h:54: warning: Function parameter or member '__ETHTOOL_DECLARE_LINK_MODE_MASK(advertising' not described in 'phylink_link_state' ./include/linux/phylink.h:54: warning: Function parameter or member '__ETHTOOL_DECLARE_LINK_MODE_MASK(lp_advertising' not described in 'phylink_link_state' Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/d1d1dea67a28117c0b0c33271b139c4455fef287.1592895969.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2020-06-26docs: f2fs: fix a broken tableJonathan Corbet1-156/+156
Commit ed318a6cc0b6 ("fscrypt: support test_dummy_encryption=v2") added an entry to the massive option table in Documentation/filesystems/f2fs.txt. The option was too wide for the formatting of the table, though, leading to a verbose and ugly warning starting with: Documentation/filesystems/f2fs.rst:229: WARNING: Malformed table. Text in column margin in table line 126. Fixing this requires formatting the whole table; let's hear it for Emacs query-replace-regexp.

2020-06-26docs: Don't push Sphinx upgrades quite so readilyJonathan Corbet1-4/+0
The sphinx-pre-install script will put out a verbose message recommending an upgrade for anybody running less than 2.4.4 - which was only released in March. So *everybody* will see that warning at this point. Let's only warn if the user is below our generally recommended version (1.7.9 currently). It might be good to put out a warning if people are explicitly making PDF files, but would need to be done in a different place and relatively few people do that.

2020-06-14security: Add LSM hooks to set*gid syscallsThomas Cedeno5-1/+40
The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba4-166/+169
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

2020-06-13net: ethernet: ti: ale: fix allmulti for nu type aleGrygorii Strashko1-9/+40
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
