license identifiers
An automated conversion using scripts/contrib/convert-spdx-licenses.py to
convert to use the standard SPDX license identifiers. Two recipes in meta-selftest
were not converted as they're that way specifically for testing. A change in
linux-firmware was also skipped and may need a more manual tweak.

Since commit [df313aa810 pseudo: Fix to work with glibc 2.34
systems] applied, it fixed native only. And nativesdk has
the similar issue
Tweak library search order, make prebuilt lib ahead of recipe lib,
after apply the fix:
...

This updates to the latest pseudo version which includes:
Revert "client: Fix some compiler warnings"
ports/linux: Always build statx support
makewrappers: Handle parameters marked as nonnull
client: Fix some compiler warnings
wrappers: Avoid -Wcast-function-type warning
In particular, this pseudo version always has statx enabled which means
we can then remove the need to make pseudo-native host distro specific
which fixes an eSDK issue.

When building pseudo-native to work with uninative, we need to ensure the
configuration will work on all supported target systems. This means
"new clone" semantics, xattr and statvfs support in particular. It is
extremely unlikely we'd run on a system without any of these but add
a check just to be sure when uninative is enabled.

New versions of glibc have an lchmod function so we need to wrap it.
Identified through a reproducibility issue in initramfs-base where
/dev/console created by mknod from coreutils changed permissions
depending on the host distro (mknod used the gnulib wrapper on most
hosts but newer ones used the libc call).

There is magic in the posts where specific variable names have specific

Rather than doing what turns out to be a rather dangerous "fixup" if

Add PSEUDO_IGNORE_PATHS, a comma separated list of path prefixes, where
any files underneath are not handled by pseudo. This allows files to
be left out of the pseudo datanase where we know we don't need the
fake root emulation. This is particularly useful if we know these files
can be deleted outside of pseudo context.

Currently, where pseudo finds a database entry for an inode but the path
doesn't match, it reuses that database entry metadata. This is causing
real world "corruption" of file attributes.
See [YOCTO #14057] for an example of this.
This can happen when files are deleted outside of pseudo context and the
inode is reused by a new file which pseduo then "sees".
Its possible the opposite could happen, it needs to reuse attributes
but this change would prevent it. As far as I can tell, we don't want
pseuo to reuse these attributes though so this code should be safer
and avoid bugs like the above.

On a tumbleweed system, "install X Y" was showing the error:
pseudo: ENOSYS for 'fsetxattr'.
which was being caused by dlsym() for that function returning NULL. This
appears to be due to it finding an unresolved symbol in libacl for this
symbol in libattr. It hasn't been resolved so its NULL. dlerror() returns
nothing since this is a valid symbol entry, its just not the one we want.
We can add the glibc version string for the symbol we actually want so we get
that version rather than the libattr/libacl one. The calls in libattr are just
wrappers around the libc version so our attaching to the libc versions should
intercept any accesses via these too.

Pseudo changes the syscall access patterns which makes it incompatible with
seccomp. Therefore intercept the seccomp syscall and alter it, pretending that
seccomp was setup when in fact we do nothing. If we error as unsupported,
utilities like file will exit with errors so we can't just disable it.
This works around issues on platforms where seccomp is enabled in file
(e.g. archlinux).

pseudo-native is special in that bitbake ends up executing it from the
sysroot-components directory before we have any workdirs for the bitbake
fakeroot worker. Since we switched to dynamically linking sqlite, it
means sqlite from the host system may be found, we really want the version
in sysroot-components. Trying to run tasks to create some special environment
for pseudo is hard and error prone. The simplest fix is to add an RPATH to
the binary so that it can correctly find the sqlite we want.
Unfortunately passing $ORIGIN into make doesn't work so well with shell
quoting so we have to fix that during do_install.

Linux system's realpath() remove trailing slashes, but pseudo's doesn't, need
make them identical.
E.g., the following code (rel.c) prints '/tmp' with system's realpath, but
pseudo's realpath prints '/tmp/':
#include <stdio.h>
#include <limits.h>
#include <stdlib.h>
int main() {
char out[PATH_MAX];
printf("%s\n", realpath("/tmp/", out));
return 0;
}
$ bitbake base-passwd -cdevshell # For pseudo env
$ gcc rel.c
$ ./a.out
/tmp/ (but should be /tmp)
This patch fixes the problem.

Back in 2010[1] we made pseudo statically link against sqlite3. Since then
the world has changed, pseudo now has separate processes for the database
in the server and the client and they have separate linking commands.
Also, whilst there were concerns about needing specific versions of sqlite3,
in the OE environment, this is always the case.
[1] http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=ad0ac0ecd38fc77daf42485489fccc10a5e1e3e7
The static sqlite3-native is causing us problems, in particular:
tmp/work/x86_64-linux/pseudo-native/1.9.0+gitAUTOINC+060058bb29-r0/recipe-sysroot-native/usr/lib/libsqlite3.a(sqlite3.o):(.data.rel+0xb0): undefined reference to `fcntl64'
which occurs if sqlite3-native was built on a machine with glibc 2.28 or later
and pseudo-native is being built on glibc before that. With dyanmical linking,
libc is backwards compatible and works but with static linking it does not.
There appears to be no easy way to avoid this other than adding a copy of
sqlite3 into the pseudo recipe. Given the static linking doesn't seem to
be required any longer due to the separate processes, drop that to fix
those issues.

While working with ostree disk generation in conjunction with wic, I
found a problem with pseudo where it tried to resolve a symlink when
it shouldn't, based on openat() flags. A C program has been
constructed to test pseudo to show that it is working properly with
the correct behavior around openat().
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <dirent.h>

int main()
{
/*
* Tested with: gcc -Wall -o app app.c ; echo "no pseudo" ;
* ./app ; echo "pseudo"; pseudo ./app
*/
system("rm -rf tdir tlink");
system("mkdir tdir");
system("ln -s tdir tlink");
DIR *dir = opendir(".");
int dfd = dirfd(dir);
int target_dfd = openat (dfd, "tlink", O_RDONLY | O_NONBLOCK |
O_DIRECTORY | O_CLOEXEC | O_NOFOLLOW);
if (target_dfd == -1) {
printf("Test 1 good\n");
} else {
printf("Test 1 failed\n");
close(target_dfd);
}
target_dfd = openat (dfd, "tlink", O_RDONLY | O_NONBLOCK |
O_DIRECTORY | O_CLOEXEC);
if (target_dfd == -1) {
printf("Test 2 failed\n");
} else {
printf("Test 2 good\n");
close(target_dfd);
}
/* Test 3 make sure the owner of the link is root */
struct stat sbuf;
if (!lstat("tlink", &sbuf) && sbuf.st_uid == 0) {
printf("Test 3 good\n");
} else {
printf("Test 3 failed\n");
}
/* Test 4 tests open with the "rb" flag, owner should not change */
int ofd = openat(dfd,"./tlink", O_RDONLY|O_CLOEXEC);

if (fstat(ofd, &sbuf) != 0)
printf("ERROR in fstat test 4\n");
else if (sbuf.st_uid == 0)
printf("Test 4 good\n");
close(ofd);
} else {
printf("Test 4 failed with openat()\n");
}
/* Test pseudo db to see the fstat() above did not delete the DB entry */
if (!lstat("tlink", &sbuf) && sbuf.st_uid == 0)
printf("Test 5 good\n");
else
printf("Test 5 failed... tlink is owned by %i and not 0\n", sbuf.st_uid);
return 0;
}

/* Tested with: gcc -Wall -o app app.c ; echo "no pseudo" ; ./app ; echo "pseudo"; pseudo ./app */

printf("This is right\n");
} else {
printf("This is broken\n");
}
return 0;
}
Many thanks to Peter Seebach for fixing the problem in the pseudo code
to use the same logic which was already there for the
AT_SYMLINK_NOFOLLOW.
Also updated is the license MD5 checksum since the master branch of

Newer distros are using new versions of glibc and coreutils which use the new glibc
renameat2 function. We need to intercept this for correct functioning of pseudo. This
is essential to ensure new distros continue to work with the project.
Also, this version has a fix for path/inode cross corruption problems which
may explain our mysterious locale permissions issues.
Many thanks to Otavio and Peter Seebach for the help in figuring this out and
