This one limits the fallout until proper enablement. - Use cpu_feature_enabled() in the idxd driver so that it can be build-time disabled through the defines in disabled-features.h. - Fix LVT thermal setup for SMI delivery mode by making sure the APIC LVT value is read before APIC initialization so that softlockups during boot do not happen at least on one machine. - Mark all legacy interrupts as legacy vectors when the IO-APIC is disabled and when all legacy interrupts are routed through the PIC" * tag 'x86_urgent_for_v5.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/sev: Check SME/SEV support in CPUID first x86/fault: Don't send SIGSEGV twice on SEGV_PKUERR x86/setup: Always reserve the first 1M of RAM x86/alternative: Optimize single-byte NOPs at an arbitrary position x86/cpufeatures: Force disable X86_FEATURE_ENQCMD and remove update_pasid() dmaengine: idxd: Use cpu_feature_enabled() x86/thermal: Fix LVT thermal setup for SMI delivery mode x86/apic: Mark _all_ legacy interrupts when IO/APIC is missing

ext4: Only advertise encrypted_casefold when encryption and unicode are enabled

2021-06-06T14:10:23Z

Encrypted casefolding is only supported when both encryption and casefolding are both enabled in the config.

ext4: fix no-key deletion for encrypt+casefold

2021-06-06T14:10:23Z

commit 471fbbea7ff7 ("ext4: handle casefolding with encryption") is missing a few checks for the encryption key which are needed to support deleting enrypted casefolded files when the key is not present. This bug made it impossible to delete encrypted+casefolded directories without the encryption key, due to errors like: W : EXT4-fs warning (device vdc): __ext4fs_dirhash:270: inode #49202: comm Binder:378_4: Siphash requires key Repro steps in kvm-xfstests test appliance: mkfs.ext4 -F -E encoding=utf8 -O encrypt /dev/vdc mount /vdc mkdir /vdc/dir chattr +F /vdc/dir keyid=$(head -c 64 /dev/zero | xfs_io -c add_enckey /vdc | awk '{print $NF}') xfs_io -c "set_encpolicy $keyid" /vdc/dir for i in `seq 1 100`; do mkdir /vdc/dir/$i done xfs_io -c "rm_enckey $keyid" /vdc rm -rf /vdc/dir # fails with the bug Fixes: 471fbbea7ff7 ("ext4: handle casefolding with encryption") Signed-off-by: Daniel Rosenberg Link: https://lore.kernel.org/r/20210522004132.2142563-1-drosen@google.com Signed-off-by: Theodore Ts'o

ext4: fix memory leak in ext4_fill_super

2021-06-06T14:10:23Z

Buffer head references must be released before calling kill_bdev(); otherwise the buffer head (and its page referenced by b_data) will not be freed by kill_bdev, and subsequently that bh will be leaked. If blocksizes differ, sb_set_blocksize() will kill current buffers and page cache by using kill_bdev(). And then super block will be reread again but using correct blocksize this time. sb_set_blocksize() didn't fully free superblock page and buffer head, and being busy, they were not freed and instead leaked. This can easily be reproduced by calling an infinite loop of: systemctl start .mount, and systemctl stop .mount ... since systemd creates a cgroup for each slice which it mounts, and the bh leak get amplified by a dying memory cgroup that also never gets freed, and memory consumption is much more easily noticed.

ext4: fix fast commit alignment issues

2021-06-06T14:10:23Z

Fast commit recovery data on disk may not be aligned. So, when the recovery code reads it, this patch makes sure that fast commit info found on-disk is first memcpy-ed into an aligned variable before accessing it. As a consequence of it, we also remove some macros that could resulted in unaligned accesses.
