The PRNG seeder daemon is introduced in TM-QPR2 which can lead to
breakage running Android 13 CTS tests depending on when the platform
and CTS tests are built.
Fix: 253185870
Test: run cts --module CtsBionicTestCases

Mostly from extra test cases, but also:
* Move the fgets size < 0 assertion into fgets.
* Use ELF aliases for strtoq/strtouq rather than duplicating code.
* Don't check uname() succeeded, since it can't fail.

R GSI on P product tests fail since pw_shell has changed. This value
has no practical use on Android, so we ignore testing it for older
vendor images.

Previously, these tests would fail if vendors modified
private/android_filesystem_config.h to add their custom AIDs, but we
did not have a good alternative that vendors could use, so we added a
special case to ignore the vendor AID ranges.
We've had a proper solution since P for this range, so it's long past
time to remove this special case.
Test: add system, vendor, odm, product, and system_ext AIDs to
config.fs, ensure that they've taken effect on cuttlefish,
pass these unit tests

1) "fix the system properties design" is written for the old protocol,
so we've already changed the design. There are no other further
planned changes.
2) "don't drag in all the macros, just the types." is not likely to
happen or be particularly impactful.
3) "Find a location suitable for these functions ..." is refering to
legacy code. More likely that this code will be removed before we
find a serious reason to fix this TODO.
4) "(73062966) We still don't have a good way ..." is stale; we fixed
this bug and added the appropriate mechanism.

Historically we've made a few mistakes where they haven't matched the
right number. And most non-Googlers are much more familiar with the
numbers, so it seems to make sense to rely more on them. Especially in
header files, which we actually expect real people to have to read from
time to time.

Note that unlike the oem_ range that is used for the vendor
partitions, we do not create oem_<n> entries for these new reserved
ranges; they will only appear in getpwent()/getgrent() if there is an
entry in the corresponding passwd/group file.

In an attempt to make bionic's reporting of users and groups more
accurate, this change makes the user / group functions do the
following:
1) Fail to query a uid/gid for a secondary user when the uid/gid
doesn't exist. Currently bionic would return successfully but with
a empty string for the name.
2) Fail to query a platform uid/gid, except a limited pre-allocated
set for a secondary user, as these are not used by second users.
3) Fail to query uids for all users for the GID-only app ranges:
CACHE_GID, EXT_GID, EXT_CACHE_GID, SHARED_GID.
4) Fail to query gids in SHARED_GID range for secondary users, as
these GIDs are only allocated for the first user.
5) Use "u#_a#_ext" and u#_a#_ext_cache" for EXT_GID and EXT_CACHE_GID
ranges. This both allows querying based on these names and
returning these names for the appropriate uids/gids.
This also consolidates the tests for better readability.
Test: these unit tests, boot

getpwnam_r() and getpwuid_r() clobber the storage used by getpwnam()
and getpwuid(). This isn't likely to be a big issue, but since we do
this right for the group functions, fix this as well as add a test.
Both use more space in buf than is actually required, but well below
their sysconf() suggested values, so we accept that to keep the code
concise.
Add tests for dealing with unaligned input buffers, particularly for
getgrnam_r() and getgrgid_r(), as they require alignment but this
wasn't being tested.
Refactor common initialization code for both passwd and group state
structs.
Remove extraneous null pointer checks; the values they were testing
were offsets of a previous pointer, so guaranteed to never actually be
null. If the underlying pointer is actually null, we're beyond repair
anyway, so accept that we'll crash.
Test: pwd/grp unit tests

We still don't have a good way to create vendor AIDs in the system or
other non-vendor partitions, therefore we keep this check disabled.

The UID range [90000..98999] is used for isolated processes that are
spawned from an application zygote. Otherwise they are identical to
regular isolated processes in the [99000..99999] range. Fix the tests to
match the new range.

Some vendors may have been using the AIDs outside the oem ranges
for long that those aids need continue to be maitained for the
existing devices. We allow them countinue to use the old AID names
and values on device launch with P and before, to give them the
period of time to adopt the new AID scheme.
Bug: 116405200
Change-Id: I0453ed14df4c0855575ef1404c596ddc6ded681b
We added a check in P that ensures all vendor provided AIDs only
appear in the carved out ranges for vendors to use. However,
upgrading devices may be using AIDs outside of this range and it is
very difficult to change these AIDs, so we waive this test for them.
Bug: 116830906
Test: test succeeds on upgrading devices

During the review of the script that generates /vendor/etc/passwd, it
was suggested that the shell be /vendor/bin/sh instead of the typical
/system/bin/sh. This has subsequently caused bionic unit tests to
fail, since they always check that the shell is set to /system/bin/sh.
In the spirit of that review, libc is modified to return
/vendor/bin/sh for the OEM AID ranges and the test is updated to
expect this.

Now that we're only processing vendor AID names that begin with
vendor_, add an explicit test to fail devices that use AID names
without this prefix.

Vendors that use config.fs will have their own uniquely named
user/group names for uids/gids that fall in the OEM ranges. We
continue to allow lookup via oem_## for these values, however the
returned structs will always include the name from config.fs, so we do
not check it for anything in the tests.

We now have a proper mechanism for OEMs to create new AIDs via
config.fs and /vendor/etc/{passwd,group}. This means that there is no
reason for OEMs to add AIDs by modifying android_filesystem_config.h,
and therefore we can add this check back.

Currently, getpwnam, getpwent, etc return successfully for any uid
from AID_APP_START (10000) to AID_USER_OFFSET (100000) for each user.
This is not correct however, as only specific ranges above
AID_APP_START are reserved as valid ranges. This change corrects this.
This is particularly important as the newly added AID_OVERFLOWUID is
65534, which is above AID_APP_START but not in any reserved range,
collided with the faulty returned values.

grp_pwd_test.cpp uses ASSERT_ where EXPECT_ is possible, causing

Remove the check that AIDs in the OEM range are not defind in

To support upcoming disk usage calculation optimizations, this change
creates a new GID for each app that will be used to mark its cached

quotactl() to track cached data on a per-app basis.

Not efficient to iterate through given the large number of Android
ids (AID). Compile warning will result if you use these functions,
telling you as much. Not for general consumption, however for
example, some filesystem tests would like to see these to perform
all corners.
About 1/4 second for getpwent, and 1/8 second for getgrent to iterate
through all reserved Android aids.

The XXXX now lines up to the underlying uid and has no offset.
Work with AID_OEM_RESERVED uids.
Test uses hard coded values to catch changes in the API expectations
that may occur in private/android_filesystem_config.h.
SideEffects: names change, some product dependencies.
