Corinna Vinschen a96d68c5bd Cygwin: s4uauth: make sure to fetch correct package id
for domain accounts we try KerbS4ULogon first, MsV1_0S4ULogon
second.  But we only fetch the package id for the supporting
authentication package (Kerberos/MsV1_0) once at the start.

Duplicate LsaLookupAuthenticationPackage call and move into the
Kerb/MsV1_0 branches so that it fetches the correct package id
for the method we call next.

Curious enough this worked before.  Apparently both methods
work with the MICROSOFT_KERBEROS_NAME_A package id.  However,
requesting and using the right authentication package id is
the prudent thing to do.

Corinna Vinschen 367c1ae161 Cygwin: mount: define binary mount as default
Commit c1023ee353 changed the way
path_conv::binmode() works.  Rather than returning three states,
O_BINARY, O_TEXT, 0, it only returned 2 states, O_BINARY, O_TEXT.  Since
mounts are only binary if they are explicitely mounted binary by setting
the MOUNT_BINARY flag, textmode is default.

This introduced a new bug.  When inheriting stdio HANDLEs from native
Windows processes, the fhandler and its path_conv are created from a
device struct only.  None of the path or mount flags get set this way.
So the mount flags are 0 and path_conv::binmode() returned 0.

After the path_conv::binmode() change it returned O_TEXT since, as
explained above, the default mount mode is textmode.

Rather than just enforcing binary mode for path_conv's created from
device structs, this patch changes the default mount mode to binary:

Replace MOUNT_BINARY flag with MOUNT_TEXT flag with opposite meaning.
Drop all explicit setting of MOUNT_BINARY.  Drop local set_flags
function, it doesn't add any value.

When looking up valid accounts by name, LookupAccountName returns
a SID and a case-correct domain name.  However, the name was input
and LookupAccountName is case-insensitive, so the name is not
necessarily written the same way as in SAM or AD.

Fix that by doing a reverse lookup on the just fetched SID.  This
fetches the account name in the correct case.  Override the
incoming name with the case correct name from LookupAccountSid.

Tamar Christina 1ba66fe8fa AArch32: Fix the build for M class semihosting
The M class cores don't support Semihosting v2 mixed mode, but we were
accidentally using the new immediates for it.  My last patch changed the
immediates which broke the build because doing a full multi-lib build
including M architectures now results in an assembler error instead of
silently doing the wrong thing.

This fixes the issue by changing the defines around such that According
to the specs any M class build uses the normal semihosting instructions.

Regtested on arm-none-eabi and no issues, using a build with m class
multilibs too.

Corinna Vinschen 0be0b8f033 Cygwin: execve: fix setting O_APPEND file offset for native child
dtable::set_file_pointers_for_exec is called from
child_info_spawn::worker to move the file position of O_APPEND
files to EOF if the child is a native child.

However, this only works correctly for the first O_APPEND
file descriptor:

- set_file_pointers_for_exec calls SetFilePointer.  The higher
  4 bytes of the desired file offset are given to SetFilePointer
  as pointer to a DWORD value.  On return, SetFilePointer returns
  the higher 4 bytes of the new file position in this DWORD.

- So for the second and subsequent descriptors the higher 4 byte
  of the file position depend on what the actual file position
  of the previous file has been set to:

- If the file is > 2 Gigs, the high offset will not be 0 anymore.

- If the desciptor points to a non-seekable file (i.e., a pipe
  or socket), SetFilePosition returns an error and sets the high
  position to -1.

Fix this by calling SetFilePointerEx instead, which does not
modify the incoming position value.

Corinna Vinschen 88605243a1 Cygwin: fix child getting another pid after spawnve
When calling spawnve, in contrast to execve, the parent has
to create the pid for the child.  With the old technique
this was simply the Windows pid, but now we have to inform
the child about its new pid.

Add a cygpid member to class child_info_spawn.  Set it in
child_info_spawn::worker, just prior to calling CreateProcess
rather than afterwards.  Overwrite cygheap->pid in
child_info_spawn::handle_spawn before calling pinfo::thisproc.
Make sure pinfo::thisproc knows the pid is already set by
setting the handle argument to INVALID_HANDLE_VALUE.

Also set procinfo->dwProcessId to myself_initial.dwProcessId
instead of to myself_initial.pid for clarity.

Tamar Christina 6d6a623e7d AArch32: Add support for HLT to Mixed Mode models
The Semihosting v2 protocol requires us to output the Armv8-a HLT instruction
when in mixed mode (SEMIHOST_V2_MIXED_MODE), however it also requires this to
be done for Armv7-a and earlier architectures.

The HLT instruction is defined in the undefined encoding space for older
architectures but simulators such as QEMU already trap on it [1] for all
architectures and is a requirement for semihosting v2 [2].

Unfortunately the GAS restricts the use of HLT to Armv8-a which requires us to
use the instruction encodings we want directly in crt0.

This patch does this, I have not updated newlib/libc/* as that is quite out of
date already.  A proper sync is needed in order to get things back in sync.

A different patch for this would be best.

Michael Haubenwallner 3956ddd9bf forkables: hardlink without WRITE_ATTRIBUTES first
When the current process has renamed (to bin) a readonly dll, we get
STATUS_TRANSACTION_NOT_ACTIVE for unknown reason when subsequently
creating the forkable hardlink. A workaround is to open the original
file with FILE_WRITE_ATTRIBUTES access, but that fails with permission
denied for users not owning the original file.

* forkable.cc (dll::create_forkable): Retry hardlink creation using the
original file's handle opened with FILE_WRITE_ATTRIBUTES access when the
first attempt fails with STATUS_TRANSACTION_NOT_ACTIVE.

Michael Haubenwallner 5a41aa6f4d forkables: Keep hardlinks disabled via shared mem.
To avoid the need for each process to check the filesystem to detect
that hardlink creation is impossible or disabled, cache this fact in
shared memory.  Removing cygfork directory while in use does disable
hardlinks creation.  To (re-)enable hardlinks creation, the cygfork
directory has to exist before the first cygwin process does fork.

	forkables needs to impossible when disabled via shared memory.
	(dll_list::update_forkables_needs): When detecting hardlink
	creation as impossible (not on NTFS) while still (we are the

Michael Haubenwallner ece7282f32 forkables: On fork failure, retry with hardlinks.
To support in-cygwin package managers, the fork() implementation must
not rely on .exe and .dll files to stay in their original location, as
the package manager's job is to replace these files.  Instead, when the
first fork try fails, and we have NTFS, we use hardlinks to the original
binaries in /var/run/cygfork/ to create the child process during the
second fork try, along the main.exe.local file to enable the "DotLocal
Dll Redirection" feature for the dlls.

The (probably few) users that need an update-safe fork manually have to
create the /var/run/cygfork/ directory for now, using:
mkdir --mode=a=rwxt /var/run/cygfork

In preparation to protect fork() against dll- and exe-updates, create
hardlinks to the main executable and each loaded dll in subdirectories
of /var/run/cygfork/, if that one exists on the NTFS file system.

The directory names consist of the user sid, the main executable's NTFS
IndexNumber, and the most recent LastWriteTime of all involved binaries
(dlls and main executable).  Next to the main.exe hardlink we create the
empty file main.exe.local to enable dll redirection.

The name of the mutex to synchronize hardlink creation/cleanup also is
assembled from these directory names, to allow for synchronized cleanup
of even orphaned hardlink directories.

The hardlink to each dynamically loaded dll goes into another directory,
named using the NTFS IndexNumber of the dll's original directory.

Michael Haubenwallner fb3e8bd88b fork: remove cygpid.N sharedmem on fork failure
When fork finally fails although both CreateProcess and creating the
"cygpid.N" shared memory section succeeded, we have to release that
shared memory section as well - before releasing the process handle.
Otherways we leave an orphan "cygpid.N" shared memory section, and any
subsequent cygwin process receiving the same PID fails to initialize.

* fork.cc (frok::parent): Call child.allow_remove in cleanup code.
