Pass POLLERR and POLLHUP to fd callbacks, as is necessary.
Crash on POLLNVAL since that means our fds are messed up.
Document the behaviour (including the fact that poll sometimes sets
POLLHUP or POLLERR even if only POLLIN was requested.
Fix the one current fd callback to do something with POLLERR|POLLHUP.

We need a slightly more sophisticated data structure to allow this,
where we record the slot not just for each fd but also for each
(fd,eventbit) where eventbit is POLLIN, POLLPRI, POLLOUT.
Document the new relaxed restriction.

The current arrangements in libxl for spawning subprocesses have two
key problems: (i) they make unwarranted (and largely undocumented)
assumptions about the caller's use of subprocesses, (ii) they aren't
integrated into the event system and can't be made asynchronous etc.
So replace them with a new set of facilities.
Primarily, from the point of view of code inside libxl, this is
libxl__ev_child_fork which is both (a) a version of fork() and (b) an
event source which generates a callback when the child dies.
>From the point of view of the application, we fully document our use
of SIGCHLD. The application can tell us whether it wants to own
SIGCHLD or not; if it does, it has to tell us about deaths of our
children.
Currently there are no callers in libxl which use these facilities.
All code in libxl which forks needs to be converted and libxl_fork
needse to be be abolished.

From: Ian Jackson @ 2012-04-25 15:55 UTC (permalink / raw)
To: xen-devel; +Cc: Roger Pau Monne, Ian Jackson
Remove a lot of unnecessary tests. Specifically, we no longer test
for standard POSIX facilities which we expect to be provided
everywhere and which we don't in any case have any alternative for.
Switch to generating config.h.in with autoheader.
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
Cc: Roger Pau Monne <roger.pau@entel.upc.edu>
Changes since v7:
* Removed AX_CHECK_PTYFUNCS (snuck in from previous patch)

- not one of the forms that C requires support for.
- However, doing the test right would require a runtime
- test, and that would make cross-compilation harder.
- Let us hope that IBM fixes the xlc bug, and also adds
- support for this kind of constant expression. In the
- meantime, this test will reject xlc, which is OK, since
- our stdbool.h substitute should suffice. We also test
- this with GCC, where it should work, to detect more

- Here is a matrix of mmap possibilities:
- mmap private not fixed
- mmap private fixed at somewhere currently unmapped
- mmap private fixed at somewhere already mapped
- mmap shared not fixed
- mmap shared fixed at somewhere currently unmapped
- mmap shared fixed at somewhere already mapped
- For private mappings, we should verify that changes cannot be read()
- back from the file, nor mmap's back from the file at a different
- address. (There have been systems where private was not correctly
- implemented like the infamous i386 svr4.0, and systems where the
- VM page cache was not coherent with the file system buffer cache
- like early versions of FreeBSD and possibly contemporary NetBSD.)
- For shared mappings, we should conversely verify that changes get
- propagated back to all the places they're supposed to be.
-
- Grep wants private fixed already mapped.
- The main things grep needs to know about mmap are:
- * does it exist and is it safe to write into the mmap'd area
- * how to use it (BSD variants) */

> - Here is a matrix of mmap possibilities:
> - mmap private not fixed
> - mmap private fixed at somewhere currently unmapped
> - mmap private fixed at somewhere already mapped
> - mmap shared not fixed
> - mmap shared fixed at somewhere currently unmapped
> - mmap shared fixed at somewhere already mapped
> - For private mappings, we should verify that changes cannot be read()
> - back from the file, nor mmap's back from the file at a different
> - address. (There have been systems where private was not correctly
> - implemented like the infamous i386 svr4.0, and systems where the
> - VM page cache was not coherent with the file system buffer cache
> - like early versions of FreeBSD and possibly contemporary NetBSD.)
> - For shared mappings, we should conversely verify that changes get
> - propagated back to all the places they're supposed to be.
> -
> - Grep wants private fixed already mapped.
> - The main things grep needs to know about mmap are:
> - * does it exist and is it safe to write into the mmap'd area
> - * how to use it (BSD variants) */

To: xen-devel; +Cc: Ian Jackson
We may need to #include <libutil.h>, and/or link with -lutil, to use
openpty, login_tty, and the like. Provide INCLUDE_LIBUTIL_H
(preprocessor constant, not always defined) and PTYFUNCS_LIBS
(makefile variable).
We link libxl against PTYFUNCS_LIBS (which comes from autoconf) rather
than UTIL_LIBS, and #include <libutil.h> where appropriate.

Acked-by: Ian Campbell <ian.campbell@citrix.com>
Changes since v7:
* Actually include the call to AX_CHECK_PTYFUNCS in this patch,
not the previous one, and regenerate configure accordingly.
Changes since v6:
* Put failure macro call in correct place so it might actually happen.
* Try both with -lutil and without.
* Patch now contains update for config.h.in.

These utility functions cope with EINTR AND ENOENT, do error logging,
and we provide a recursive version to delete whole directory trees.

We will want to reuse the fd-sending code, so break it out into its
own function, and provide the corresponding sending function.

To: xen-devel; +Cc: Ian Jackson
Convert libxl_run_bootloader to an ao_how-taking function.
It's implemented in terms of libxl__bootloader_run, which can be used
internally. The resulting code is pretty much a rewrite.
Significant changes include:
- We direct the bootloader's results to a file, not a pipe. This
makes it simpler to deal with as we don't have to read it
concurrently along with everything else.
- We now issue a warning if we find unexpected statements in the
bootloader results.
- The arrangements for buffering of bootloader input and output
are completely changed. Now we have a fixed limit of 64k
on output, and 4k on input, and discard the oldest data when
this overflows (which it shouldn't). There is no timeout
any more.
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
Acked-by: Ian Campbell <ian.campbell@citrix.com>
Changes since v6:
* Use libxl__ev_child_inuse rather than testing pid directly.
* Fix a code style error.
* Properly initialise the sub-operations' aos in _init.
* Bugfixes.

This involves adding a new log feature to libxl__datacopier, and then
using it.
If the bootloader exits nonzero we print the log filename in a log
message from libxl.

Mark the gc produced by AO_GC and EGC_GC with the gcc feature
__attribute__((unused)). This allows the use of EGC_INIT and
STATE_AO_GC by functions which do actually use the gc.
This is convenient because those functions might want to use the ao or
egc, rather than the gc; and also because it means that functions
which morally ought to be fishing any gc they use out of an egc or
state structure can be written do so regardless of whether the gc is
actually used right then.

Remove this obsolete hook. Callers inside libxl which create and reap
children should use the mechanisms provided by the event system.
(This has no functional difference since there is no way for
ctx->waitpid_instead ever to become set.)

In the next patch these variables will turn into actual pointers.
To clarify that patch, prepare the ground by changing these variables
from "struct foo var" to "struct foo var[1]". This enables accesses
to them and their members to be made as if they were pointers.
No functional change.

libxl__spawn_spawn becomes a callback-style asynchronous function.
The implementation is now in terms of libxl__ev_* including
libxl_ev_child.
All the callers need to be updated. This includes the device model
spawning functions libxl__create_device_model and
libxl__create_stubdom; these are replaced with libxl__spawn_local_dm
and libxl__spawn_stubdom. libxl__confirm_device_model_startup is
abolished; instead the dm spawner calls back.
(The choice of which kind of device model to create is lifted out of
what used to be libxl__create_device_model, because that function was
indirectly recursive. Recursive callback-style operations are clumsy
because they require a pointer indirection for the nested states.)
Waiting for proper device model startup it is no longer notionally
optional. Previously the code appeared to tolerate this by passing
NULL for various libxl__spawner_starting* parameters to device model
spawners. However, this was not used anywhere.
Conversely, the "for_spawn" parameter to libxl__wait_for_offspring is
no longer supported. It remains as an unused formal parameter to
avoid updating, in this patch, all the call sites which pass NULL.
libxl__wait_for_offspring is in any case itself an obsolete function,
so this wrinkle will go away when its callers are updated to use the
event system. Consequently libxl__spawn_check is also abolished.
The "console ready" callback also remains unchanged in this patch.
The API for this needs to be reviewed in the context of the event
series and its reentrancy restrictions documented.
Thus their callers need to be updated. These are the domain creation
functions libxl_domain_create_new and _restore. These functions now
take ao_hows, and have a private state structure.
However domain creation remains not completely converted to the event
mechanism; in particular it runs the outward-facing function
libxl_run_bootloader with a NULL ao_how, which is quite wrong. As it
happens in the current code this is not a bug because none of the rest
of the functionality surrounding the bootloader call will mind if the
event loop is reentered in the middle of its execution.
The file-scope function libxl__set_fd_flag which was used by the
previous spawn arrangements becomes unused and is removed; other
places in libxl can use libxl_fd_set_nonblock and
libxl_fd_set_cloexec, which of course remain.
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
Changes since v7:
* Rename libxl__spawn_stubdom to libxl__spawn_stub_dm (and ..._state);
rename the state's stubdom_* members to dm_*.
* Eliminate the union between the two dm creation states in
libxl__domain_create_state. Instead, the domain creation code
simply uses libxl__stub_dm_spawn_state.dm directly, if we're
taking the local dm path.
* Remove a spurious "break".
* In domain creation, move the PV non-qemu case into the switch.
* Code style fixes.
* Constify some convenience aliases.
* Improve comments (including typo fixes).

Document the concurrent access policies for libxl__ao and libxl__egc,
and their corresponding gcs.
Fix a violation of the policy:
If an ao was submitted and a callback requested, and while the
initiating function was still running on the original thread, the ao
is completed on another thread, the completing thread would improperly
concurrently access the ao with the initiating thread.

This will be used for reporting, during domain creation, that the
console is ready.
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
Changes since v7:
* If aop->how.callback, actually add the aop to the for_callback list (!)
* Document the threadsafety of aop's, and make appropriate cross-references.
* Allocate the actual aop from its thread's egc; do not free it.
* Remove pointless code motion of libxl__ao_create.
* Minor formatting fixes.

Change to use libxl__zalloc, where allocation failure is fatal.
Also remove a spurious semicolon from the helper macro.

Remove the old console callback. (Its reentrancy properties were
troublesome: in principle, the event loop might be reentered during
the callback, and the libxl__domain_create_state swept out from under
the feet of the domain creation.)
As a side effect of the new code arrangements, the console callback
for non-bootloader-using PV guests now occurs near the end of domain
creation, in the same place as for HVM guests, rather than near the
start.
The new arrangements should in principle mean that by the time the
console is described as ready by the callback, the xenstore key is
indeed ready. So in the future the timeout might be removed from
the console client.

Abolish libxl_fork. Its only callers were in xl. Its functionality
is now moved elsewhere, as follows:
* The "logging version of fork", which is what it was billed as, is now
xl_fork, which also dies on failure.
* Closing the xenstore handle in the child is now done in
libxl__ev_child_fork, which is the only remaining place where fork
is called in libxl.
* We provide a new function libxl__ev_child_xenstore_reopen for
in-libxl children to make the ctx useable for xenstore again.
* Consequently libxl__spawn_record_pid now no longer needs to mess
about with its own xenstore handle. As a bonus it can now just use
libxl__xs_write.
Also, since we have now converted all the forkers in libxl, we can
always honour the fork_replacement childproc hook - so do so.

Cancel the bootloader (specifically, by sending it a signal) if the
domain is seen to disappear from xenstore.
We use a new utility event source libxl__domaindeathcheck which
provides a convenient wrapper for the xenstore watch.
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
Acked-by: Ian Campbell <ian.campbell@citrix.com>
Changes since v7:
* Add a comment explaining why we use a watch on the domain's
xenstore path rather than @releaseDomain.
* Fix typo in error message.
