2020-11-07r8169: disable hw csum for short packets on all chip versionsHeiner Kallweit
RTL8125B has same or similar short packet hw padding bug as RTL8168evl. The main workaround has been extended accordingly, however we have to disable also hw checksumming for short packets on affected new chip versions. Instead of checking for an affected chip version let's simply disable hw checksumming for short packets in general. v2: - remove the version checks and disable short packet hw csum in general - reflect this in commit title and message Fixes: 0439297be951 ("r8169: add support for RTL8125B") Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Link: https://lore.kernel.org/r/7fbb35f0-e244-ef65-aa55-3872d7d38698@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-11-07perf/core: Fix a memory leak in perf_event_parse_addr_filter()kiyin(尹亮)
As shown through runtime testing, the "filename" allocation is not always freed in perf_event_parse_addr_filter(). There are three possible ways that this could happen: - It could be allocated twice on subsequent iterations through the loop, - or leaked on the success path, - or on the failure path. Clean up the code flow to make it obvious that 'filename' is always freed in the reallocation path and in the two return paths as well. We rely on the fact that kfree(NULL) is NOP and filename is initialized with NULL. This fixes the leak. No other side effects expected.

2020-11-06ext4: clean up the JBD2 API that initializes fast commitsHarshad Shirwadkar
This patch removes jbd2_fc_init() API and its related functions to simplify enabling fast commits. With this change, the number of fast commit blocks to use is solely determined by the JBD2 layer. So, we move the default value for minimum number of fast commit blocks from ext4/fast_commit.h to include/linux/jbd2.h. However, whether or not to use fast commits is determined by the file system. The file system just sets the fast commit feature using jbd2_journal_set_features(). JBD2 layer then determines how many blocks to use for fast commits (based on the value found in the JBD2 superblock). Note that the JBD2 feature flag of fast commits is just an indication that there are fast commit blocks present on disk. It doesn't tell JBD2 layer about the intent of the file system of whether to it wants to use fast commit or not. That's why, we blindly clear the fast commit flag in journal_reset() after the recovery is done.

Secondly, don't pass inode to ext4_fc_track_link/create/unlink functions. inode can be found inside these functions as d_inode(dentry). However, rename path is an exeception.

2020-11-06ext4: correctly report "not supported" for {usr,grp}jquota when !CONFIG_QUOTAKaixu Xia
The macro MOPT_Q is used to indicates the mount option is related to quota stuff and is defined to be MOPT_NOSUPPORT when CONFIG_QUOTA is disabled. Normally the quota options are handled explicitly, so it didn't matter that the MOPT_STRING flag was missing, even though the usrjquota and grpjquota mount options take a string argument. It's important that's present in the !CONFIG_QUOTA case, since without MOPT_STRING, the mount option matcher will match usrjquota= followed by an integer, and will otherwise skip the table entry, and so "mount option not supported" error message is never reported. [ Fixed up the commit description to better explain why the fix works. --TYT ] Fixes: 26092bf52478 ("ext4: use a table-driven handler for mount options") Signed-off-by: Kaixu Xia <kaixuxia@tencent.com> Link: https://lore.kernel.org/r/1603986396-28917-1-git-send-email-kaixuxia@tencent.com Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@kernel.org

2020-11-06bpf: Update verification logic for LSM programsKP Singh
The current logic checks if the name of the BTF type passed in attach_btf_id starts with "bpf_lsm_", this is not sufficient as it also allows attachment to non-LSM hooks like the very function that performs this check, i.e. bpf_lsm_verify_prog. In order to ensure that this verification logic allows attachment to only LSM hooks, the LSM_HOOK definitions in lsm_hook_defs.h are used to generate a BTF_ID set. Upon verification, the attach_btf_id of the program being attached is checked for presence in this set.

2020-11-06net/sunrpc: return 0 on attempt to write to "transports"Dan Carpenter
You can't write to this file because the permissions are 0444. But it sort of looked like you could do a write and it would result in a read. Then it looked like proc_sys_call_handler() just ignored it. Which is confusing. It's more clear if the "write" just returns zero. Also, the "lenp" pointer is never NULL so that check can be removed.
