Do you think 5.10 is stable currently? Thanks for your help again. :) Hi Young, See https://www.kernel.org/releases.html for a list of the LTS branches. The 5.10 kernel is already designated as LTS and should be used by most stable tree users; this is the preferrable kernel to adopt right now. The AMD hardware enablement stuff won't be backported on top of 5.4. -- Thanks, Sasha

Question for AMD patches

by Young Hsieh

Hello, This is Young Hsieh from Uber and currently I am in Uber infra team and in charge of server system design. Nice to e-meet you! :) We are working on AMD Milan platform with Debian, and notice there are some patches for performance and security improvements, which are not implemented in LTS kernels (4.14/4.19/5.4) yet. On our side, we prefer to use the general LTS kernel release instead of a customized kernel, in case we will not align on major fixes down the road. So would like to know if there is any plan to backport these patches and if so, what is the timeline? Thanks a lot again for any advice. Cheers, **************************************** Young Hsieh Uber Hardware Engineer ****************************************

[PATCH 6/8] ext4: Fix deadlock with fs freezing and EA inodes

by Jan Kara

Xattr code using inodes with large xattr data can end up dropping last inode reference (and thus deleting the inode) from places like ext4_xattr_set_entry(). That function is called with transaction started and so ext4_evict_inode() can deadlock against fs freezing like: CPU1 CPU2 removexattr() freeze_super() vfs_removexattr() ext4_xattr_set() handle = ext4_journal_start() ... ext4_xattr_set_entry() iput(old_ea_inode) ext4_evict_inode(old_ea_inode) sb->s_writers.frozen = SB_FREEZE_FS; sb_wait_write(sb, SB_FREEZE_FS); ext4_freeze() jbd2_journal_lock_updates() -> blocks waiting for all handles to stop sb_start_intwrite() -> blocks as sb is already in SB_FREEZE_FS state Generally it is advisable to delete inodes from a separate transaction as it can consume quite some credits however in this case it would be quite clumsy and furthermore the credits for inode deletion are quite limited and already accounted for. So just tweak ext4_evict_inode() to avoid freeze protection if we have transaction already started and thus it is not really needed anyway.

Szmigiero" <maciej.szmigiero(a)oracle.com> Date: Sat, 5 Dec 2020 01:48:08 +0100 Subject: [PATCH] KVM: mmu: Fix SPTE encoding of MMIO generation upper half Commit cae7ed3c2cb0 ("KVM: x86: Refactor the MMIO SPTE generation handling") cleaned up the computation of MMIO generation SPTE masks, however it introduced a bug how the upper part was encoded: SPTE bits 52-61 were supposed to contain bits 10-19 of the current generation number, however a missing shift encoded bits 1-10 there instead (mostly duplicating the lower part of the encoded generation number that then consisted of bits 1-9). In the meantime, the upper part was shrunk by one bit and moved by subsequent commits to become an upper half of the encoded generation number (bits 9-17 of bits 0-17 encoded in a SPTE). In addition to the above, commit 56871d444bc4 ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation") has changed the SPTE bit range assigned to encode the generation number and the total number of bits encoded but did not update them in the comment attached to their defines, nor in the KVM MMU doc.
