56c4815402 libcli/smb: Fix failure of Smb3UnixTests.test_create_context_reparse
On tumbleweed at least the definition in py_reparse_put of 'reserved' as
'unsigned' causes the tag value to be overwritten. Note: ParseTuple is
given a format of 'Kk' where
  K = unsigned long long (for tag)
  k = unsigned long      (for reserved)

The problem is 'reserved' is defined as 'unsigned' which on a
64 bit linux system has size 4. The size however of the 'unsigned long' type
on the same 64 bit system is 8. This causes 'tag' to be overwritten by
the value of 'reserved' because it's destination size is smaller than
expected.

0425b0fcbe libcli:auth: Remove unreachable code (CID 1272968)
For us to reach the statement ‘if (0 < len1)’, ‘len1’ must be equal to
‘len2’, and they must not both be equal to zero. That cannot be the case
if ‘len1’ is equal to zero, and therefore the ‘else’ branch cannot be
reached.

b91e257f56 libcli: New routine symlink_target_path for [MS-SMB2] 2.2.2.2.1.1
Right now the only user is the user-space symlink following in
smbd. We will use it in libsmb as well to correctly handle
STOPPED_ON_SYMLINK. When trying to upstream that code I found the
previous_slash function incredibly hard to understand.

This new routine makes copy of "const char *_name_in", so that we can
replace previous_slash with a simple strrchr_m. If that's too
slow (which I doubt, this is "only" chasing symlinks) we can always do
something smarter again.

78f728063a libcli/security: claims_conversions: check for NULL in claims array
If by mistake we end up with a NULL in our array of claims pointers,
it is better to return an error than crash.

There can be NULLs in the array if a resource attribute ACE has a
claim that uses 0 as a relative data pointer. Samba assumes this means
a NULL pointer, rather than a zero offset.

d33ed63147 libcli/security: allow round-trip for conditional ACE octal integers
The string "00" will decode into an integer tagged as octal, but
`snprintf("%#oll")` will write the string "0", which would decode as
decimal, so the in the SDDL1->SD1->SDDL2->SD2 round trip, SD1 would
not be the same as SD2.

The effect is really only relevant to SDDL, which wants to remember
what base the numbers were presented in, though the fuzzers and tests
don't directly compare SDDL, which can have extra spaces and so forth.

e004a5a444 libcli/security: SDDL decode stops earlier with too many ACEs
For this purpose, "too many" means we know for sure that it won't fit
in packet format, even if all the ACEs are minimum size. This would
fail anyway.

Credit to OSS-Fuzz, who found that 50 thousand ACEs that took more
than 60 seconds to decode. This will now fail after 4096 ACEs which
should be about 150 times faster than 50k (because the realloc loop in
quadratic), so ~0.5 seconds in the fuzz context with sanitisers
enabled. That is still slowish, but SDDL parsing is not a critical
path and without address sanitisers it will be many times faster.
