Pull UBI/UBIFS/JFFS2 updates from Richard Weinberger: "This pull request contains mostly fixes for UBI, UBIFS and JFFS2: UBI: - Fix a regression around producing a anchor PEB for fastmap. Due to a change in our locking fastmap was unable to produce fresh anchors an re-used the existing one a way to often. UBIFS: - Fixes for endianness.

Merge tag 'compat-ioctl-5.5' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann: "As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers. I have patches for those as well, but they need more testing or possibly a rewrite" * tag 'compat-ioctl-5.5' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground: (42 commits) scsi: sd: enable compat ioctls for sed-opal pktcdvd: add compat_ioctl handler compat_ioctl: move SG_GET_REQUEST_TABLE handling compat_ioctl: ppp: move simple commands into ppp_generic.c compat_ioctl: handle PPPIOCGIDLE for 64-bit time_t compat_ioctl: move PPPIOCSCOMPRESS to ppp_generic compat_ioctl: unify copy-in of ppp filters tty: handle compat PPP ioctls compat_ioctl: move SIOCOUTQ out of compat_ioctl.c compat_ioctl: handle SIOCOUTQNSD af_unix: add compat_ioctl support compat_ioctl: reimplement SG_IO handling compat_ioctl: move WDIOC handling into wdt drivers fs: compat_ioctl: move FITRIM emulation into file systems gfs2: add compat_ioctl support compat_ioctl: remove unused convert_in_user macro compat_ioctl: remove last RAID handling code compat_ioctl: remove /dev/raw ioctl translation compat_ioctl: remove PCI ioctl translation compat_ioctl: remove joystick ioctl translation ...

ubi: Fix producing anchor PEBs

2019-11-17T21:45:57Z

When a new fastmap is about to be written UBI must make sure it has a free block for a fastmap anchor available. For this ubi_update_fastmap() calls ubi_ensure_anchor_pebs(). This stopped working with 2e8f08deabbc ("ubi: Fix races around ubi_refill_pools()"), with this commit the wear leveling code is blocked and can no longer produce free PEBs. UBI then more often than not falls back to write the new fastmap anchor to the same block it was already on which means the same erase block gets erased during each fastmap write and wears out quite fast. As the locking prevents us from producing the anchor PEB when we actually need it, this patch changes the strategy for creating the anchor PEB. We no longer create it on demand right before we want to write a fastmap, but instead we create an anchor PEB right after we have written a fastmap. This gives us enough time to produce a new anchor PEB before it is needed. To make sure we have an anchor PEB for the very first fastmap write we call ubi_ensure_anchor_pebs() during initialisation as well. Fixes: 2e8f08deabbc ("ubi: Fix races around ubi_refill_pools()") Signed-off-by: Sascha Hauer Signed-off-by: Richard Weinberger
