Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

UDF file system
|
|
===============
|
|
|
|
If you encounter problems with reading UDF discs using this driver,
|
|
please report them according to MAINTAINERS file.
|
|
|
|
Write support requires a block driver which supports writing. Currently
|
|
dvd+rw drives and media support true random sector writes, and so a udf
|
|
filesystem on such devices can be directly mounted read/write. CD-RW
|
|
media however, does not support this. Instead the media can be formatted
|
|
for packet mode using the utility cdrwtool, then the pktcdvd driver can
|
|
be bound to the underlying cd device to provide the required buffering
|
|
and read-modify-write cycles to allow the filesystem random sector writes
|
|
while providing the hardware with only full packet writes. While not
|
|
required for dvd+rw media, use of the pktcdvd driver often enhances
|
|
performance due to very poor read-modify-write support supplied internally
|
|
by drive firmware.
|
|
|
|
-------------------------------------------------------------------------------
|
|
|
|
The following mount options are supported:
|
|
|
|
=========== ======================================
|
|
gid= Set the default group.
|
|
umask= Set the default umask.
|
|
mode= Set the default file permissions.
|
|
dmode= Set the default directory permissions.
|
|
uid= Set the default user.
|
|
bs= Set the block size.
|
|
unhide Show otherwise hidden files.
|
|
undelete Show deleted files in lists.
|
|
adinicb Embed data in the inode (default)
|
|
noadinicb Don't embed data in the inode
|
|
shortad Use short ad's
|
|
longad Use long ad's (default)
|
|
nostrict Unset strict conformance
|
|
iocharset= Set the NLS character set
|
|
=========== ======================================
|
|
|
|
The uid= and gid= options need a bit more explaining. They will accept a
|
|
decimal numeric value and all inodes on that mount will then appear as
|
|
belonging to that uid and gid. Mount options also accept the string "forget".
|
|
The forget option causes all IDs to be written to disk as -1 which is a way
|
|
of UDF standard to indicate that IDs are not supported for these files .
|
|
|
|
For typical desktop use of removable media, you should set the ID to that of
|
|
the interactively logged on user, and also specify the forget option. This way
|
|
the interactive user will always see the files on the disk as belonging to him.
|
|
|
|
The remaining are for debugging and disaster recovery:
|
|
|
|
===== ================================
|
|
novrs Skip volume sequence recognition
|
|
===== ================================
|
|
|
|
The following expect a offset from 0.
|
|
|
|
========== =================================================
|
|
session= Set the CDROM session (default= last session)
|
|
anchor= Override standard anchor location. (default= 256)
|
|
lastblock= Set the last block of the filesystem/
|
|
