We have moved the gerrit service to a new server and at the same time allowed
direct access to gerrit. This change updates the '.gitreview' file to reflect
these changes. If you have an existing checkout you might need to update your
.ssh/config file to remove the git-minix alias and edit .git/config to update
the gerrit repository from 'git-minix' to the new url sheme:
ssh://username@gerrit.minix3.org:2222/minix

The job option enable the usage of pipes to communicate with sub-makes.
On MINIX, it seems that there is possibility of receiving an EAGAIN on
such reads, even when it had previously been tested for POLLIN using
poll().
This patch is a workaround, by wrapping the read operation within a
do {} while(errno == EAGAIN && ...) loop.

. select callback on close() on a pipe
would falsely revive a read-select on
the pipe
. the extra pipe_check catches it
. fixes the new import of the netbsd
make in -j N mode (make jobs that communicate
with pipes)
. define _MINIX_SYSTEM for all system code from minix.service.mk
. hide some system-level declarations and definitions
behind _MINIX_SYSTEM to cleanly fix host tool build problems on
Minix (such as: NONE being defined and paddr_t being used but not
declared)
. the similar definition _SYSTEM is unsuitable as it changes the
values of errno definitions

has to run as root so it can flush the FS cache; needed to
force FS cache misses for unmapped pages.
See the comment in test74.c for a full description of what the tested
cases are.
also re-enable filemap on arm
This fcntl requests all cached blocks associated with the minor device
number associated with the regular file are invalidated. If the file
is a block special, invalidate the blocks associated with that minor
device instead.
This is to be used for a test that tests unmapped file-mapped memory
ranges whose blocks are not in the cache and therefore must be fetched
from a FS.

Change the kernel to add features to vircopy and safecopies so that
transparent copy fixing won't happen to avoid deadlocks, and such copies
fail with EFAULT.
Transparently making copying work from filesystems (as normally done by
the kernel & VM when copying fails because of missing/readonly memory)
is problematic as it can happen that, for file-mapped ranges, that that
same filesystem that is blocked on the copy request is needed to satisfy
the memory range, leading to deadlock. Dito for VFS itself, if done with
a blocking call.
This change makes the copying done from a filesystem fail in such cases
with EFAULT by VFS adding the CPF_TRY flag to the grants. If a FS call
fails with EFAULT, VFS will then request the range to be made available
to VM after the FS is unblocked, allowing it to be used to satisfy the
range if need be in another VFS thread.
Similarly, for datacopies that VFS itself does, it uses the failable
vircopy variant and callers use a wrapper that talk to VM if necessary
to get the copy to work.
. kernel: add CPF_TRY flag to safecopies
. kernel: only request writable ranges to VM for the
target buffer when copying fails
. do copying in VFS TRY-first
. some fixes in VM to build SANITYCHECK mode
. add regression test for the cases where
- a FS system call needs memory mapped in a process that the
FS itself must map.
- such a range covers more than one file-mapped region.
. add 'try' mode to vircopy, physcopy
. add flags field to copy kernel call messages
. if CP_FLAG_TRY is set, do not transparently try
to fix memory ranges
. for use by VFS when accessing user buffers to avoid
deadlock
. remove some obsolete backwards compatability assignments
. VFS: let thread scheduling work for VM requests too
Allows VFS to make calls to VM while suspending and resuming
the currently running thread. Does currently not work for the
main thread.
. VM: add fix memory range call for use by VFS

Diagnostics messages are printed using locally generated requests,
using KERNEL as the calling endpoint. No reply should be sent for
such cases. This check was accidentally lost with the previous
removal of tty_reply().
Change-Id: I4b76215a4d90e927b0071675d89d861aa399abb3
The constants ANY, NONE, and SELF are now a function of the way the
endpoint number is split between a generation number and a process
slot number, rather than the other way around. This allows for the
use of bit masking and shifting instead of the previous (and more
expensive) multiplication and division.

ld.so linked with gold didn't work - gold was not generating
the _DYNAMIC ptr in the first GOT entry, leaving it zero, causing
mayhem for ld.so.
. patch for gold: always generate _DYNAMIC ptr. submitted upstream,
more info here: https://sourceware.org/bugzilla/show_bug.cgi?id=16900
. revert "REMOVE ME: Static tests for now" - we can link tests dynamically
This reverts commit 3e0a3993deb831eb5abcd1c1a2cb1246b43f8d1d.

These 2 patches are from upstream binutils and together properly
detect whether -ldl is necessary and available to build ld and gold
in plugins mode, instead of hard-coding its usage always. This lets
us build ld and gold on *bsd and minix systems, which do not have
or need -ldl for dl*() functions.

The syntax of the stat(1) command varies between Linux and FreeBSD.
This prevented `x86_hdimage.sh -i` from succeeding on FreeBSD 10.0.
The fix is to use the NetBSD stat from the tooldir for all systems.

This patch adds pthread compatibility by using libmthread.
To use this with a program using pthreads, you have to replace
#include <pthread>
with
#define _MTHREADIFY_PTHREADS
#include <minix/mthreads>
This also changes the initialization function to be a constructor, which
is implicitly called before the call to main. This allows for
conformance with pthreads, while not paying a high price by checking on
each mthread_* call whether the library has been initialized or not.
As mthread_init is now a constructor, it also has been set as static, and
relevent calls removed from programs using it.

This default is overriden by curl when it is available on the system.
This allows for the fetch script to work on MINIX systems without any
additions from PKGSRC, while requiring either a netbsd compatible ftp or
curl to be installed on other systems.

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
