2020-07-13S390: Replace HTTP links with HTTPS onesAlexander A. Klimov
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.

2020-06-29s390/debug: remove raw viewHeiko Carstens
There is not a single user of the debug raw view. Therefore remove it before anybody uses it. If anybody would make use of the view it would expose the struct __debug_entry definition to userspace and really would make it uapi. This wouldn't be good, since the definition is suboptimal and needs to be changed. Right now the structure definition is only defined to be uapi, however there is no user.

2020-06-03vfio-ccw: Introduce a new CRW regionFarhan Ali
This region provides a mechanism to pass a Channel Report Word that affect vfio-ccw devices, and needs to be passed to the guest for its awareness and/or processing. The base driver (see crw_collect_info()) provides space for two CRWs, as a subchannel event may have two CRWs chained together (one for the ssid, one for the subchannel). As vfio-ccw will deal with everything at the subchannel level, provide space for a single CRW to be transferred in one shot.

2020-06-02vfio-ccw: Enable transparent CCW IPL from DASDJared Rossi
Remove the explicit prefetch check when using vfio-ccw devices. This check does not trigger in practice as all Linux channel programs are intended to use prefetch. It is expected that all ORBs issued by Linux will request prefetch. Although non-prefetching ORBs are not rejected, they will prefetch nonetheless. A warning is issued up to once per 5 seconds when a forced prefetch occurs. A non-prefetch ORB does not necessarily result in an error, however frequent encounters with non-prefetch ORBs indicate that channel programs are being executed in a way that is inconsistent with what the guest is requesting. While there is currently no known case of an error caused by forced prefetch, it is possible in theory that forced prefetch could result in an error if applied to a channel program that is dependent on non-prefetch.

So move the pure prototype kdocs of ("s390: include/asm/debug.h add kerneldoc markups") from debug.h to debug.c and merge them with the old function docs. Also, I had the impression that kdoc typically is at the implementation in the compile unit rather than at the prototype in the header file. While at it, update the short kdoc description to distinguish the different functions. And a few more consistency cleanups.

Instead of keeping the documentation inside s390dbf.rst, move them to arch/s390/include/asm/debug.h, using standard kernel-doc markups. Keeping the documentation close to the code helps to keep it updated. It also makes easier to document other stuff inside debug.h, as all it needs is to add kernel-doc markups inside it, as the file will be already be included at the produced documentation. - Those were converted to kerneldoc using this script specially designed to parse ths file, and manually editted: <script> use strict; my $mode = ""; my $parameter = ""; my $ret = ""; my $descr = ""; sub add_var($) { my $ln = shift; $ln =~ s/^\s+//; $ln =~ s/\s+$//; return if ($ln eq ""); $ln =~ s/^(\S+)\s+/$1\t/; print " * \@$ln\n"; } sub add_return($) { my $ln = shift; print " *\n * Return:\n" if ($mode ne "Return Value:"); $ln =~ s/^\s+//; $ln =~ s/\s+$//; return if ($ln eq ""); print " * - $ln\n"; } sub add_description($) { my $ln = shift; print " *\n * \n" if ($mode ne "Description:"); $ln =~ s/^\s+//; $ln =~ s/\s+$//; return if ($ln eq ""); print " * $ln\n"; } sub flush_results() { print " */\n\n"; } while (<>) { if (m/^[\-]+$/) { flush_results(); $mode = ""; $parameter = ""; $ret = ""; $descr = ""; next; } if (m/(Parameter:)(.*)/) { print " *\n" if ($mode eq "func"); add_var($2); $mode = $1; next; } if (m/(Return Value:)(.*)/) { add_return($2); $mode = $1; next; } if (m/(Description:)(.*)/) { add_description($2); $mode = $1; next; } if ($mode eq "Parameter:") { add_var($_); next; } if ($mode eq "Return Value:") { add_return($_); next; } if ($mode eq "Description:") { add_description($_); next; } next if (m/^\s*$/); if (m/^\S+.*\s\*?(\S+)\s*\(/) { if ($mode eq "") { print "/**\n * $1()\n"; } else { print " * $1()\n"; } $mode="func"; } } flush_results(); </script> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

2018-09-09Drop all 00-INDEX files from Documentation/Henrik Austad
This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway. As a starting point, remove all index-files and references to 00-INDEX and see where the discussion is going. Signed-off-by: Henrik Austad <henrik@austad.us> Acked-by: "Paul E.
