libcli/smb: create explicit talloc stackframe in reparse_data_buffer_marshall()

2025-05-19T09:11:29+00:00

This is needed in order to allow helper functions to use talloc_tos().

libcli: New routine symlink_target_path for [MS-SMB2] 2.2.2.2.1.1

2024-07-04T15:26:36+00:00

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.

reparse: Tighten reparse point length check

2024-05-06T20:55:37+00:00

test_create_reparse shows that the length checks need to be precise,
not just checking for overflow.

libsmb: Fix parsing symlink reparse points

2023-09-08T17:24:19+00:00

Untested code is broken code. For symlinks we need to hand over the
full reparse buffer into symlink_reparse_buffer_parse(), as this is
also used for the smb2 error response handling. For that, the
"reserved" field in [MS-FSCC] 2.1.2.4 Symbolic Link Reparse Data
Buffer is used for the "unparsed" field.

The goal of this is to eventually remove reparse_symlink.c once we

libcli: Add general reparse point data parsing

2023-08-10T13:40:31+00:00

When we retrieve reparse point data, we don't know before what we
get. Right now all we do is expect a symlink, but we could get other
types as well.
