[PATCH v2 1/2] HID: hid-plantronics: Add mic mute mapping and generalize quirks

by Wade Wang

From: Terry Junge <linuxhid(a)cosmicgizmosystems.com> Add mapping for headset mute key events. Remove PLT_QUIRK_DOUBLE_VOLUME_KEYS quirk and made it generic. The quirk logic did not keep track of the actual previous key so any key event occurring in less than or equal to 5ms was ignored. Remove PLT_QUIRK_FOLLOWED_OPPOSITE_VOLUME_KEYS quirk. It had the same logic issue as the double key quirk and was actually masking the as designed behavior of most of the headsets. It's occurrence should be minimized with the ALSA control naming quirk that is part of the patch set.

Due to two bugs in damon_commit_targets() and damon_commit_schemes(), which are called from damon_commit_ctx(), some user inputs can be ignored, and some mmeory objects can be leaked. Fix those. Note that only DAMON sysfs interface users are affected. Other DAMON core API user modules that more focused more on simple and dedicated production usages, including DAMON_RECLAIM and DAMON_LRU_SORT are not using the buggy function in the way, so not affected. This patch (of 2): When new DAMON targets are added via damon_commit_targets(), the newly created targets are not deallocated when updating the internal data (damon_commit_target()) is failed. Worse yet, even if the setup is successfully done, the new target is not linked to the context. Hence, the new targets are always leaked regardless of the internal data setup failure. Fix the leaks.

[RFC PATCH] NFSD: Encode COMPOUND operation status on page boundaries

by cel＠kernel.org

From: Chuck Lever <chuck.lever(a)oracle.com> J. David reports an odd corruption of a READDIR reply sent to a FreeBSD client. xdr_reserve_space() has to do a special trick when the @nbytes value requests more space than there is in the current page of the XDR buffer. In that case, xdr_reserve_space() returns a pointer to the start of the next page, and then the next call to xdr_reserve_space() invokes __xdr_commit_encode() to copy enough of the data item back into the previous page to make that data item contiguous across the page boundary. But we need to be careful in the case where buffer space is reserved early for a data item that will be inserted into the buffer later. One such caller, nfsd4_encode_operation(), reserves 8 bytes in the encoding buffer for each COMPOUND operation. However, a READDIR result can sometimes encode file names so that there are only 4 bytes left at the end of the current XDR buffer page (though plenty of pages are left to handle the remaining encoding tasks). If a COMPOUND operation follows the READDIR result (say, a GETATTR), then nfsd4_encode_operation() will reserve 8 bytes for the op number (9) and the op status (usually NFS4_OK). In this weird case, xdr_reserve_space() returns a pointer to byte zero of the next buffer page, as it assumes the data item will be copied back into place (in the previous page) on the next call to xdr_reserve_space(). nfsd4_encode_operation() writes the op num into the buffer, then saves the next 4-byte location for the op's status code. The next xdr_reserve_space() call is part of GETATTR encoding, so the op num gets copied back into the previous page, but the saved location for the op status continues to point to the wrong spot in the current XDR buffer page because __xdr_commit_encode() moved that data item. After GETATTR encoding is complete, nfsd4_encode_operation() writes the op status over the first XDR data item in the GETATTR result. The NFS4_OK status code (0) makes it look like there are zero items in the GETATTR's attribute bitmask. The patch description of commit 2825a7f90753 ("nfsd4: allow encoding across page boundaries") [2014] remarks that NFSD "can't handle a new operation starting close to the end of a page." This behavior appears to be one reason for that remark. Break up the reservation of the COMPOUND op num and op status data items into two distinct 4-octet reservations. Thanks to XDR data item alignment restrictions, a 4-octet buffer reservation can never straddle a page boundary.

[PATCHSET v6.2 4/5] xfs: realtime reverse-mapping support

by Darrick J. Wong

Hi all, This is the latest revision of a patchset that adds to XFS kernel support for reverse mapping for the realtime device. This time around I've fixed some of the bitrot that I've noticed over the past few months, and most notably have converted rtrmapbt to use the metadata inode directory feature instead of burning more space in the superblock. At the beginning of the set are patches to implement storing B+tree leaves in an inode root, since the realtime rmapbt is rooted in an inode, unlike the regular rmapbt which is rooted in an AG block. Prior to this, the only btree that could be rooted in the inode fork was the block mapping btree; if all the extent records fit in the inode, format would be switched from 'btree' to 'extents'. The next few patches enhance the reverse mapping routines to handle the parts that are specific to rtgroups -- adding the new btree type, adding a new log intent item type, and wiring up the metadata directory tree entries. Finally, implement GETFSMAP with the rtrmapbt and scrub functionality for the rtrmapbt and rtbitmap and online fsck functionality. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy!
