Yes, I should have -written them *in* DocBook, but hey, I was in a hurry. - -OK, doctool is a program that gathers snippets of a docbook document and -puts them all together in the right order. There are three -places that it gets snippets from: - -1. The document that you tell it you want "finished" - -2. blocks of SGML in *.sgml files - -3. comments in source code - -The first of these is the template file, which is to say, it's a -normal SGML file (sort of). This file is the first one read, and -includes such things as your <book> tags etc. It contains commands to -doctool to tell it where to put the other parts. - -The second, the *.sgml files, contain one or more blocks of SGML. -To work with doctool, each of these snippets must begin and end -with matching tags, must have an id="" attribute, and the start/end -tags must begin at the beginning of the line. For example: - -<foo id="frob-45"> - stuff goes here -</foo> -<bar id="frob-48"> - stuff goes here -</bar> - -In this example, the file contains two snippets, one marked by "foo" -and one barked by "bar", with id's "from-45" and "from-48". Note that -I made up the foo and bar tags. You'd usually use a <sect1> tag or -something useful like that. Stuff outside the blocks is ignored. - -The third is simply an encapsulation of the second in comments, like this: - -/* DOCTOOL-START -<foo id="frob-45"> - stuff goes here -</foo> -DOCTOOL-END */ - -The DOCTOOL-START and DOCTOOL-END things are special. Doctool uses -those to know which parts of which comments are useful, and which -parts are the useless source code stuff ;-) - - -OK, so now we've got all these snippets of SGML floating around. What -do we do with them? Well, inside the template document (#1 in our -list up there) you'd put text snippets that said "ok, put them -here". Each text snippet looks like this: - -DOCTOOL-INSERT-frob- - -Note that the "frob-" part tells doctool to pull in all the snippets -with IDs that start with "frob-", in alphabetical (well, asciibetical -at the moment) order. So, by saying "DOCTOOL-INSERT-frob-" you'd get -all the "frob-*" snippets, like "frob-45" and "frob-48". - -If you just said DOCTOOL-INSERT-frob, it inserts the snippet named -"frob" and no others. - -Note that no snippet will ever be inserted more than once, no matter -how many DOCTOOL-INSERTs you have. - -There's two other tricks doctool has. If it finds a snippet with an ID -like "int-*" (i.e. int-frob-45) that means that snippet of documentation -is for the "internal" version only. The "int-" is discarded, and if -the -i option is given to doctool, this snippet is treated as if the -int- wasn't there. Without the -i, the int-* snippets are ignored -completely. - -If a snippet has "add-" on it, like "add-frob-45", that's an addendum. -Each time a snippet named without the add- is found, doctool looks for -an addendum with exactly that same name (i.e. frob-45 looks for -add-frob-45). If it finds any, it puts them just before the last line -of the non-add snippet (so that it's *inside* the main snippet's -block, not after it). Example: - -<sect1 id="frob-45"> - some text -</sect1> -<sect1 id="add-frob-45"> - more text -</sect1> - -This would yield: - -<sect1 id="frob-45"> - some text - more text -</sect1> - -You should use the same outermost tags as the main snippet, but only -because it sets the proper nesting rules for what's enclosed. - -You can use add- and int- at the same time, but always do add-int- and -not int-add- (i.e. "add-int-frob-45"). - - -OK, now for doctool command line options. - --m tells doctool to "fix" the Makefile (not makefile) to include the -extra dependencies needed by the file you're generating. You need to -manually include dependencies on the Makefile itself and the template -file; doctool only includes the snippet files (sources etc) that it -actually pulled content from. Note: this isn't perfect! Someone can -come along and add a new snippet to a source file, and doctool would -never know. Sometimes, it's best to just rebuild the docs all the -time. - --i means to include snippets with the "int-" prefix on their IDs. Use -with -b to make internal and public versions from the same sources. - -"-d dir" tells doctool to scan all the files in that directory (and -subdirectories, recursively) for files that might contain snippets of -SGML. These include *.c, *.cc, *.h, and *.sgml. The idea is that -most of the documentation would be in a *.sgml file named after the -source (i.e. foo.c -> foo.sgml) but some commentary within the source -might be useful in the docs as well. SGML files (*.sgml) do not need -the DOCTOOL-START/END tags but the others do. - --o sets the output file. Without -o, the file goes to stdout (ick). - --s tells doctool to supress a "source directory prefix". What this -means is that, in the generated output doctool puts comments that say -where each snippet comes from (for debugging), which includes the full -path sometimes, but if you use -s, you can tell doctool to cut off -that prefix. For example, -/usr/people/dj/src/cygnus/latest/devo/winsup/foo.c might get shortened -to winsup/foo.c if you gave "-s -/usr/people/dj/src/cygnus/latest/devo/". Cygnus makefiles could -just use -s $(srcdir) most of the time. - --b changes the ID for the <book> tag. db2html uses the <book> tag's -ID as the default subdirectory name and/or html file name to create -the book with. You'd need this to generate two books (internal vs -public) from the same source. - -The only other thing you'd add to the command line is the ONE template -file you want to pull in. diff --git a/winsup/doc/effectively.sgml b/winsup/doc/effectively.sgml deleted file mode 100644 index fd0c0d447..000000000 --- a/winsup/doc/effectively.sgml +++ /dev/null @@ -1,211 +0,0 @@ -<sect1 id="using-effectively"> -<title>Using Cygwin effectively with Windows</title> - -<para> -Cygwin is not a full operating system, and so must rely on Windows for -accomplishing some tasks.

For example, sometimes files used by system -services end up owned by the SYSTEM account and not writable by regular users. -</para> -<para>The quickest way to delete the entire tree if you run into this problem is to -change the ownership of all files and folders to your account. To do this in -Windows Explorer, right click on the root Cygwin folder, choose Properties, then -the Security tab.

Select -Advanced, then go to the Owner tab and make sure your account is listed as -the owner. Select the 'Replace owner on subcontainers and objects' checkbox -and press Ok. After Explorer applies the changes you should be able to -delete the entire tree in one operation.

An ACE contains three parts:</para> - -<itemizedlist spacing="compact"> -<listitem><para>the type of the ACE </para></listitem> -<listitem><para>permissions, described with a DWORD </para></listitem> -<listitem><para>the SID, for which the above mentioned permissions are -set </para></listitem> -</itemizedlist> - -<!-- Is the historical note really important here? we're at version 1.5.9, after all.. --> -<para>The two important types of ACEs are the `access allowed ACE' and the -`access denied ACE'. The ntsec functionality only used `access allowed ACEs' up -to Cygwin version 1.1.0. Later versions also use `access denied ACEs' -to reflect the UNIX permissions as well as possible.</para> - -<para>The possible permissions on objects are more detailed than in -UNIX. For example, the permission to delete an object is different -from the write permission.</para> - -<para>With the aforementioned method NT is able to grant or revoke permissions -to objects in a far more specific way. But what about cygwin? In a POSIX -environment it would be fine to have the security behavior of a POSIX -system. The NT security model is MOSTLY able to reproduce the POSIX model. -The ntsec method tries to do this in cygwin.</para> - -<para>You ask "Mostly? Why mostly???"

The creation of this semaphore -can be found in sigproc.cc, function `getsem'. The first parameter to the -function call `CreateSemaphore' is an SA. Without ntsec this SA -assigns default security to the semaphore. There is a simple disadvantage: -Only the owner of the process may send signals to it. Or, in other words, -if the owner of the process is not a member of the administrators' group, -no administrator may kill the process! This is especially annoying, if -processes are started via service manager.</para> - -<para>Ntsec now assigns an SA to the process control semaphore, that -has each permission set for the user of the process, for the -administrators' group and for `system', which is a synonym for the -operating system itself. The creation of this SA is done by the function -`sec_user', that can be found in `shared.cc'. Each member of the -administrators' group is now allowed to send signals to any process -created in Cygwin, regardless of the process owner.</para> - -<para>Moreover, each process now has the appropriate security settings, when -it is started via `CreateProcess'. You will find this in function -`spawn_guts' in module `spawn.cc'. The security settings for starting a -process in another user context have to add the SID of the new user, too. -In the case of the `CreateProcessAsUser' call, sec_user creates an SA with -an additional entry for the sid of the new user.</para> - -</sect2> - -<sect2 id="ntsec-files"><title id="ntsec-files.title">File permissions</title> - -<para>If ntsec is turned on, file permissions are set as in UNIX. An SD is -assigned to the file containing the owner and group and ACEs for the -owner, the group and `Everyone'.</para> - -<para>The complete settings of UNIX like permissions can be found in the file -`security.cc'. The two functions `get_nt_attribute' and `set_nt_attribute' -are the main code. The reading and writing of the SDs is done by the -functions `read_sd' and `write_sd'. `write_sd' uses the function `BackupRead' -instead of the simpler function `SetFileSecurity' because the latter is -unable to set owners different from the caller.</para> - -<para>If you are creating a file `foo' outside of Cygwin, you will see something -like the following on <command>ls -ln</command>:</para> - -<para>If your login is member of the administrators' group:</para> -<screen> - rwxrwxrwx 1 544 513 ... foo -</screen> -<para>if not:</para> -<screen> - rwxrwxrwx 1 1000 513 ... foo -</screen> - -<para>Note the user and group IDs. 544 is the UID of the administrators' group. -This is a `feature' <literal>:-P</literal> of WinNT.

Cygwin maps Win32 file ownership and permissions to the -more standard, older UNIX model by default. Cygwin version 1.1 introduces -support for ACLs according to the system calls used on newer versions of -Solaris. This ability is used when the `ntsec' feature is switched on which -is described in <xref linkend="ntsec"></xref>. -The chmod call maps UNIX-style permissions -back to the Win32 equivalents.

With version 1.1.3 Cygwin introduced a mechanism for setting real -and effective UIDs under Windows NT/W2K. This is described in -<xref linkend="ntsec"></xref>. As of version 1.5.13, the Cygwin developers -are not aware of any feature in the Cygwin DLL that would allow users to gain -privileges or to access objects to which they have no rights under Windows. -However there is no guarantee that Cygwin is as secure as the Windows it runs -on. Cygwin processes share some variables and are thus easier targets of -denial of service type of attacks. -</para> - -<para>Under Windows 9x, the situation is considerably different. Since a -security model is not provided, Cygwin fakes file ownership by making all -files look like they are owned by a default user and group id. As under NT, -file permissions can still be determined by examining their read/write/execute -status. Rather than return an unimplemented error, under Windows 9x, the -chown call succeeds immediately without actually performing any action -whatsoever. This is appropriate since essentially all users jointly own the -files when no concept of file ownership exists.</para> - -</sect2> - -<sect2 id="ov-hi-files"><title>File Access</title> <para>Cygwin supports -both Win32- and POSIX-style paths, using either forward or back slashes as the -directory delimiter. Paths coming into the DLL are translated from Win32 to -POSIX as needed.

It then creates a suspended -child process using the Win32 CreateProcess call. Next, the parent -process calls setjmp to save its own context and sets a pointer to -this in a Cygwin shared memory area (shared among all Cygwin -tasks).

The child then -sets the mutex the parent is waiting on and blocks on another mutex. -This is the signal for the parent to copy its stack and heap into the -child, after which it releases the mutex the child is waiting on and -returns from the fork call. Finally, the child wakes from blocking on -the last mutex, recreates any memory-mapped areas passed to it via the -shared area, and returns from fork itself.</para> - -<para>While we have some -ideas as to how to speed up our fork implementation by reducing the -number of context switches between the parent and child process, fork -will almost certainly always be inefficient under Win32.

Because there is no way to do an actual exec under -Win32, Cygwin has to invent its own Process IDs (PIDs).

The immediate consequence is that Cygwin system -functions are interruptible unless special care is taken to avoid -this. We go to some lengths to prevent the sig_send function that -sends signals from being interrupted.
