There is magic in the posts where specific variable names have specific
magic. For that magic to work, "path" needs to be used not "pathname" as
is currently there. Fix this, which fixes path issues on systems using
statx (Ubuntu 20.04 in particular).

Where files are link()'d and one is unlink()'d, pseudo's fd mappings
can become confused. Add a patch to try and improve this for the common
usecases we see.

Rather than doing what turns out to be a rather dangerous "fixup" if
we see a file with a different path but the same inode as another file
we've previously seen, throw and abort. Direct the user to a wiki page
where we can maintain information about what this error means.

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.

Pseudo tests for an item being renamed to itself only after
information about it has been deleted. Move the test to before
we change the database.
Note that pseudo does not support renameat2(), but neither does
glibc.

We have a significant number of outstanding patches to pseudo. Rather than
queue these up as patches, create a branch in the upstream repo and use that
until such times as we have someone with the time/skills to properly review
these for master in the pseudo repo.

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).

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.

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>
#include <unistd.h>
#include <fcntl.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 (ofd >= 0) {
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;
}
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("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
pseudo has had the SPDX data updated.

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
fixing it.

If sqlite3 is built with FTS5 it uses log() from libm, it sqlite3 is built
with READLINE it uses tgetent from a curses lib and readline from libreadline,
if it is built using deflate from libz ... , but all that linkage is lost
if we manually statically link so explicitely extract extra static linking
options from pkg-config and force them into pseudo as well.
This commit obsoletes (so include the implicit revert)

In a heavily loaded container, the child process might not started
before the parent process had terminated. The child process attempts to
signal the parent with SIGUSR1. If the parent had terminated, the
parent becomes PID 1, which is generally init. When it signaled pid 1,
it caused the docker mini-init to terminate.
This doesn't happen in a traditional system, as systemd/sysvinit is
protected to only root users can signal it.

The 0600 modes were coming from fopen/freopen/etc., because those
don't specify a filesystem mode (just an access mode like "r" or
"w"). Use 0666 & ~umask. (And then the PSEUDO_FS_MODE macro masks
in the 0600 bits we want to be sure are present.)

Pseudo 1.7 adds an experimental feature (which I think needs more testing
before it becomes the default) allowing the pseudo client to store modes
and uid/gid values in extended attributes rather than using the sqlite
database. On most Linux-like systems, this works only if the underlying
file is a plain file or a directory.
Also added is a profiling feature to allow some amount of reporting on
the wall-clock time the client spends in wrappers, processing operations,
or in IPC. This feature is not intendeded to be precisely accurate, but
gives a good overview of where time is going.
Based on the results from the profiling feature, the client now suppresses
OP_OPEN and OP_EXEC messages if the server is not logging messages, and
no longer uses constant dynamic allocation and free cycles for canonicalized
paths.
There's a few other likely-looking optimizations being considered, but
this seemed like a good cutoff for now.
1.7.1 fixes two bugs, one affecting mostly XFS systems with 64-bit
inode values, and one affecting code that called realpath(x, NULL), such
as the RPM backend.
1.7.2 fixes an indirect side-effect of the chmod fixes to deal with
umask 0700, which had no effect with opkg 0.2.4 but appears to cause
failures with 0.3.0.
1.7.3 prevents mkdirat() (and mkfifoat()) from setting errno on success,
because glibc's localedef inexplicably errors out if errno was set, even
if the operation's actual return code (which it tests) indicated
success.

There was a stupid logic error controlling the diagnostic for
a "possible" mismatch involving trailing slashes and whether or
not a node was believed to be a directory. Specifically, a diagnostic
got printed any time a lookup for a directory *didn't* have a
trailing slash, as well as in the (actually intended) case where
a non-directory lookup *did*.
No other changes, but that one is probably significant.

pseudo 1.6.3 merges (with some changes) the changes from
Peter A. Bigot to make --without-fallback-passwd work. It
also adds a proposed fix for Yocto bug #7097, which has
passed the obvious tests I could think of.
pseudo 1.6.4 fixes a silly configure bug introduced with
1.6.3.

pseudo 1.6.2 fixes problems with 64-bit inodes and some underlying issues
involving file renames that could occasionally cause very strange behaviors
files being deleted, linked, or renamed, mostly observed as strange
recovery if an inode got reused.

Pseudo now automatically tries to shut down the server after running
single commands under pseudo ("pseudo <cmd>"), which means it can
print a useless "server already offline" message in some cases. The
message has been changed to a debugging message only.
The glibc symbol versions for memcpy were being applied to non-x86
targets, unintentionally, which broke builds for at least some targets.
(But pseudo doesn't usually get built for targets so it didn't
get noticed right away.)

This uprevs pseudo to 1.6. This merges in all of the existing
fixes, and also adds partial support for extended attributes,
including storing arbitrary extended attributes in the database,
and also interpreting the posix permissions ACLs as chmod
requests.
The extended attribute support means we need xattr.h, the simplest
way to be sure of this is to build attr before pseudo, which doesn't
take long.

Remove all PR = "r0" from all .bb files in oe-core. This was done
with the command sed -e '/^PR.*=.*r0\"/d' recipes*/*/*.bb -i
We've switching to the PR server, PR bumps are no longer needed and
this saves people either accidentally bumping them or forgetting to
remove the lines (r0 is the default anyway).

pseudo 1.5's enable-force-async works great, unless you use a host
where, inexplicably, stat(2) reports inconsistent and changing values
for a file's size or times for some time unless a file has been fsynced,
in which case you might want a way to cause an fsync to work.
Also noticed that some recent changes never made it into the docs, so
I did a little cleanup there. And changed the way NDEBUG suppresses
pseudo's debug messages, so arguments to them with possible side
effects (like calls into functions in another translation unit) can be
omitted, which should drastically reduce computational time if anyone
ever uses NDEBUG.

The pseudo 1.5 update is a moderately experimental set of changes
which ought to improve performance. With these changes, pseudo
uses an in-memory sqlite database which is lushed on exit,
the protocol is changed to reduce waiting for server responses,
and pseudo can suppress any and all fsync/fdatasync type operations.
This last feature is optional, and not on by default, so we need
to pass in an extra configure argument, but that argument wouldn't
be known to an older configure, so... Enter PSEUDO_EXTRA_OPTS which
is passed to configure, and which pseudo_1.5.bb sets by default to
"--enable-force-async". (I haven't added it in pseudo_git.bb, but
maybe it should be changed; I'm not quite as sure there.)
The justification for these changes is that, for most of the real-world
build cases I deal with, they produce a 25% or more reduction in the
build time of a project. This increases when a system is heavily
loaded.

The 1.4.4 fix replaced possible double-prepending of chroot paths
with possible non-prepending of chroot paths. After significant
evaluation, have settled on a single prepending of the chroot
path as a workable compromise.

The pseudo 1.4.2 linkat() implementation had a broken edge case
in which you could end up with chroot paths being doubled when
using plain link() calls instead of linkat() calls.
