KernelNewbies:

• Linux_4.13

Last updated at 2017-12-30 01:29:51

Linux 4.13 has been released on Sun, 3 Sep 2017.

Summary: This release adds support in Ext4 for very large number of directory entries, support in Ext4 for extended attributes up to 64k, improvements in asynchronous I/O, improved error handling in background writes, improved error handling in the block layer, kernel TLS acceleration, and many other improvements.

1. Prominent features

1.1. Asynchronous I/O improvements

The asynchronous I/O implementation in Linux has some deficiencies, one of them is that it unexpectedly blocks in some situations. This release adds a way for asynchronous I/O to return errors instead of blocking.

Code: commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

1.2. Ext4 support for a larger number of directory entries

This release adds "largedir", which allows ext4 directories to support over 2 billion directory entries (assuming ~64 byte file names; in practice, users will run into practical performance limits first). This feature adds a "incompatible feature" flag.

Code: commit

1.3. Ext4 support for bigger extended attribute values

This release adds support for extended attribute values up to 64k. It also implements a deduplication feature so that if multiple files have the same xattr value (for example, Windows ACL's stored by Samba), only one copy will be stored on disk for encoding and caching efficiency. This feature adds a "incompatible feature" flag.

1.4. Kernel TLS acceleration

As a way to microoptimize TLS traffic, Facebook created an in-kernel TLS acceleration that slightly accelerates the performance of protocols such as https. Only symmetric crypto is done in the kernel, keys are passed by userspace after the handshake is complete.

Code: commit, commit

1.5. Improved block layer and background writes error handling

Error handling in some parts of the Linux I/O stack is not good as it could be. For example, when the background write process fails, only the first task to call fsync will see the error and any subsequent task calling fsync on a file will get back 0 (unless another writeback error occurs in the interim). This release adds a new way to handle the errors during background writes, making possible to reliable report errors on fsync. This release also adds an improved error handling in the block layer so that upper parts of the storage stack may get a more detailed view of I/O problems and react accordingly.

1.6. CIFS defaults to SMB3.0

Due to recent publicity about security vulnerabilities in the much older CIFS dialect, move the default dialect to the widely accepted (and quite secure) SMB3.0 dialect from the old default of the CIFS dialect. Both Microsoft and CERT now strongly recommend not using the older CIFS dialect (SMB Security Best Practices "recommends disabling SMBv1"). SMB3 is both secure and widely available: in Windows 8 and later, Samba and Macs. Users can still choose to explicitly mount with the less secure dialect (for old servers) by choosing "vers=1.0" on the cifs mount

2. Core (various)

• (FEATURED) Add nonblocking feature to asynchronous I/O writes commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• exec: Limit arg stack to at most 75% of _STK_LIM commit

• kcmp(2): add KCMP_EPOLL_TFD mode to compare epoll target files commit

• proc: extend information about epoll target files in fdinfo/<fd> commit

• kobject: support passing in variables for synthetic uevents commit

• stackprotector: ascii armor the stack canary (recommended LWN article) commit, commit, commit, commit, commit

• IRQ based next prediction (recommended LWN article) commit, commit

• cgroup

  • Make debug cgroup support v2 and thread mode commit

  • Make debug an implicit controller on cgroup2 which is enabled by "cgroup_debug" boot param commit

  • Implement nsdelegate mount option which makes cgroup namespaces delegation boundaries. If set, cgroup behaves as if write permission based delegation took place at namespace boundaries - writes to the resource control knobs from the namespace root are denied and migration crossing the namespace boundary aren't allowed from inside the namespace commit

• locking: Add CONFIG_REFCOUNT_FULL to enable the full refcount_t implementation which has the validation but is slightly slower. When not enabled, efcount_t uses the basic unchecked atomic_t routines, which results in no code changes compared to just using atomic_t directly commit

• RCU locking

  • Remove Classic SRCU. Classic SRCU was only ever intended to be a fallback in case of issues with Tree/Tiny SRCU, and the latter two are doing quite well in testing commit

  • Remove SPARSE_RCU_POINTER Kconfig option commit

  • Remove debugfs tracing commit

  • Remove the RCU_KTHREAD_PRIO Kconfig option commit

  • Remove the now-obsolete PROVE_RCU_REPEATEDLY Kconfig option commit

  • Eliminate NOCBs CPU-state Kconfig options, they are used only in testing and redundant with the rcu_nocbs= boot parameter commit

  • rcuperf: Add ability to performance-test call_rcu() and friends commit, add writer_holdoff boot parameter commit

• task scheduler: deadline scheduler: Base GRUB reclaiming on the inactive utilization (solves fairness issues) commit

• GDB scripts: add lx-fdtdump command to dumps the flattened device tree passed to the kernel from the bootloader commit

• Thin archives make default for all archs (minimum binutils version raised to 2.20) commit

• GCC plugins: Add the randstruct plugin, which randomizes the layout of selected structures at compile time, as a probabilistic defense against attacks that need to know the layout of structures within the kernel commit

• IRQs: expose internals in a debugfs interface commit

• objtool: Major rewrite of objtool. Instead of only tracking frame pointer changes, it now tracks all stack-related operations, including all register saves/restores. In addition to making stack validation more robust, this also paves the way for undwarf generation commit

• tty: add TIOCGPTPEER ioctl to safely open the "peer" end of a PTY file descriptor by using the dentry cached by devpts commit

• fscrypt: Add support for 128-bit AES commit

• fault-inject: support systematic fault injection, a /proc/<pid>/fail-nth file is added that allows failing 0-th, 1-st, 2-nd and so on calls systematically commit, commit
