Currently, EROFS supports 4KB fixed-sized output transparent file compression,

as illustrated below::
|
||||
Data compression
|
||||
----------------
|
||||
EROFS implements LZ4 fixed-sized output compression which generates fixed-sized
|
||||
compressed data blocks from variable-sized input in contrast to other existing
|
||||
fixed-sized input solutions. Relatively higher compression ratios can be gotten
|
||||
by using fixed-sized output compression since nowadays popular data compression
|
||||
algorithms are mostly LZ77-based and such fixed-sized output approach can be
|
||||
benefited from the historical dictionary (aka. sliding window).

In details, original (uncompressed) data is turned into several variable-sized
|
||||
extents and in the meanwhile, compressed into physical clusters (pclusters).
|
||||
In order to record each variable-sized extent, logical clusters (lclusters) are
|
||||
introduced as the basic unit of compress indexes to indicate whether a new
|
||||
extent is generated within the range (HEAD) or not (NONHEAD). Lclusters are now
|
||||
fixed in block size, as illustrated below::
|
||||
|
||||
Currently each on-disk physical cluster can contain 4KB (un)compressed data
|
||||
at most. For each logical cluster, there is a corresponding on-disk index to
|
||||
describe its cluster type, physical cluster address, etc.

See "struct z_erofs_vle_decompressed_index" in erofs_fs.h for more details.
|
||||
A physical cluster can be seen as a container of physical compressed blocks
|
||||
which contains compressed data. Previously, only lcluster-sized (4KB) pclusters
|
||||
were supported. After big pcluster feature is introduced (available since
|
||||
Linux v5.13), pcluster can be a multiple of lcluster size.
|
||||
|
||||
For each HEAD lcluster, clusterofs is recorded to indicate where a new extent
|
||||
starts and blkaddr is used to seek the compressed data. For each NONHEAD
|
||||
lcluster, delta0 and delta1 are available instead of blkaddr to indicate the
|
||||
distance to its HEAD lcluster and the next HEAD lcluster. A PLAIN lcluster is
|
||||
also a HEAD lcluster except that its data is uncompressed. See the comments
|
||||
around "struct z_erofs_vle_decompressed_index" in erofs_fs.h for more details.
|
||||
|
||||
If big pcluster is enabled, pcluster size in lclusters needs to be recorded as
|
||||
well. Let the delta0 of the first NONHEAD lcluster store the compressed block
|
||||
count with a special flag as a new called CBLKCNT NONHEAD lcluster. It's easy
|
||||
to understand its delta0 is constantly 1, as illustrated below::

|<----- a big pcluster (with CBLKCNT) ------>|<-- -->|
|
||||
a lcluster-sized pcluster (without CBLKCNT) ^
|
||||
|
||||
If another HEAD follows a HEAD lcluster, there is no room to record CBLKCNT,
|
||||
but it's easy to know the size of such pcluster is 1 lcluster as well.

|

Linux内核开发者认为安全非常重要。因此，我们想要知道当一个有关于
|
||||
安全的漏洞被发现的时候，并且它可能会被尽快的修复或者公开。请把这个安全
|
||||
漏洞报告给Linux内核安全团队。
|
||||
|
||||
1) 联系
|
||||
|
||||
linux内核安全团队可以通过email<security@kernel.org>来联系。这是
|
||||
一组独立的安全工作人员，可以帮助改善漏洞报告并且公布和取消一个修复。安
|
||||
全团队有可能会从部分的维护者那里引进额外的帮助来了解并且修复安全漏洞。
|
||||
当遇到任何漏洞，所能提供的信息越多就越能诊断和修复。如果你不清楚什么
|
||||
是有帮助的信息，那就请重温一下admin-guide/reporting-bugs.rst文件中的概述过程。任
|
||||
何攻击性的代码都是非常有用的，未经报告者的同意不会被取消，除非它已经
|
||||
被公布于众。
|
||||
|
||||
2) 公开
|
||||
|
||||
Linux内核安全团队的宗旨就是和漏洞提交者一起处理漏洞的解决方案直
|
||||
到公开。我们喜欢尽快地完全公开漏洞。当一个漏洞或者修复还没有被完全地理
|
||||
解，解决方案没有通过测试或者供应商协调，可以合理地延迟公开。然而，我们
|
||||
期望这些延迟尽可能的短些，是可数的几天，而不是几个星期或者几个月。公开
|
||||
日期是通过安全团队和漏洞提供者以及供应商洽谈后的结果。公开时间表是从很
|
||||
短（特殊的，它已经被公众所知道）到几个星期。作为一个基本的默认政策，我
|
||||
们所期望通知公众的日期是7天的安排。
|
||||
|
||||
3) 保密协议
|
||||
|
||||
Linux内核安全团队不是一个正式的团体，因此不能加入任何的保密协议。
