[PATCH v38 00/39] LSM: Module stacking for AppArmor

[PATCH v38 00/39] LSM: Module stacking for AppArmor

[Casey Schaufler]

This patchset provides the changes required for
the AppArmor security module to stack safely with any other.
There are additional changes required for SELinux and Smack
to coexist. These are primarily in the networking code and
will be addressed after these changes are upstream.

v38: Rebase to 6.0-rc7
     - Discard the implementation of /proc/self/attr/context
     - Discard the implementation of /proc/self/attr/display_lsm
     - Implement a system call lsm_self_attr() which provides
       a complete list of LSM process attributes.
     - Implement a system call lsm_module_list() which provides
       a list of the security modules active on the system.
     - Implement a pair of prctl() options PR_LSM_ATTR_SET
       and PR_LSM_ATTR_GET. These are used to control the LSM
       that provides the values in /proc/.../attr entries.
     - Make more of the infrastructure data changes early in the
       patch set in support of the new system calls.
     - Add a user interface header uapi/linux/lsm.h which contains
       the format of data provided by lsm_self_attr() and the
       integer LSM identifier values.
v37: Rebase to 5.19-rc3
     - Audit changes should be complete, all comments have been
       addressed.
     - Address indexing an empty array for the case where no
       built in security modules require data in struct lsmblob.
     - Fix a few checkpatch complaints.
v36: Rebase to 5.19-rc1
     - Yet another rework of the audit changes. Rearranging how the
       timestamp is managed allows auxiliary records to be generated
       correctly with a minimum of fuss.
     - In the end no LSM interface scaffolding remains. Secids have
       been replaced with lsmblob structures in all cases, including
       IMA and NetLabel.
v35: Rebase to 5.18-rc2
     - Address the case where CONFIG_SECURITY is enabled but
       no security modules that use secid slots are included.
       The resulting blob.secid[0] instances, although never
       present in a call path, raised concerns.
     - Address the case in interface_lsm where the BPF module
       returns -EINVAL, resulting in a failed setting of the
       value that would be otherwise allowed.
v34: Rebase to 5.18-rc1
     - Incorporate feedback on the audit generation.
v33:
     - Rework the supplimental audit record generation once more,
       this time taking pseudo-code provided by Paul Moore as a
       basis. The resulting code is considerably simpler and fits
       better with the existing code flow.
v32: Rebase to 5.17-rc2
     - Incorporate additional feedback from v30.
v31: Rebase to 5.16-rc4
     - Incorporate feedback from Paul Moore on the audit
       component changes.
v30: Rebase to 5.16-rc1
     - Replace the integrity sub-system reuse of the audit
       subsystem event matching functions with IMA specific
       functions. This is done because audit needs to maintain
       information about multiple security modules in audit
       rules while IMA to restricts the information to a single
       security module.
     - The binder hooks have been changed and are no longer
       called with sufficient information to identify the
       interface_lsm. Pass that information in the binder
       message, and use that in the compatibility decision.
     - Refactor the audit changes.
v29: Rebase to 5.15-rc1
     - Rework the supplimental audit record generation. Attach
       a list of supplimental data to the audit_buffer and
       generate the auxiliary records as needed on event end.
       This should be usable for other auxiliary data, such as
       container IDs. There is other ongoing audit work that
       will require integration with this.
v28: Rebase to 5.14-rc2
     - Provide IMA rules bounds checking (patch 04)
     - Quote contexts in MAC_TASK_CONTEXTS and MAC_OBJ_CONTEXTS
       audit records because of AppArmor's use of '=' in context
       values. (patch 22,23)
v27: Fixes for landlock (patch 02)
     - Rework the subject audit record generation. This version is
       simpler and reflects feedback from Paul Moore. (patch 22)
v26: Rebase to 5.13-rc1
     - Include the landlock security module.
     - Accomodate change from security_task_getsecid() to
       security_task_getsecid_obj() and security_task_getsecid_subj().
v25: Rebase to 5.12-rc2
     Incorporate feedback from v24
     - The IMA team suggested improvements to the integrity rule
       processing.
v24: Rebase to 5.11-rc1
     Incorporate feedback from v23
     - Address the IMA team's concerns about "label collisions".
       A label collision occurs when there is ambiguity about
       which of multiple LSMs is being targeted in the definition
       of an integrity check rule.  A system with Smack and
       AppArmor would be unable to distinguish which LSM is
       important to an integrity rule referrencing the label
       "unconfined" as that label is meaningful to both.
       Provide a boot option to specify which LSM will be used in
       IMA rules when multiple LSMs are present. (patch 04)
       Pull LSM "slot" identification from later audit patches in
       in support of this (patch 03).
     - Pick up a few audit events that need to include supplimental
       subject context records that had been missed in the
       previous version.
v23: Rebase to 5.10-rc4
     Incorporate feedback from v22
     - Change /proc/*/attr/display to /proc/*/attr/interface_lsm to
       make the purpose clearer. (patch 0012)
     - Include ABI documentation. (patch 0012, 0022)
     - Introduce LSM documentation updates with the patches where
       the interfaces are added rather than at the end. (patch 0012, 0022)
     Include more maintainers and mail lists in To: and Cc: directives.
v22: Rebase to 5.10-rc1
v21: Rebase to 5.9-rc4
     Incorporate feedback from v20
     - Further revert UDS SO_PEERSEC to use scaffolding around
       the interfaces that use lsmblobs and store only a single
       secid. The possibility of multiple security modules
       requiring data here is still a future problem.
     - Incorporate Richard Guy Briggs' non-syscall auxiliary
       records patch (patch 0019-0021) in place of my "supplimental"
       records implementation. [I'm not sure I've given proper
       attestation. I will correct as appropriate]
v20: Rebase to 5.9-rc1
     Change the BPF security module to use the lsmblob data. (patch 0002)
     Repair length logic in subject label processing (patch 0015)
     Handle -EINVAL from the empty BPF setprocattr hook (patch 0020)
     Correct length processing in append_ctx() (patch 0022)
v19: Rebase to 5.8-rc6
     Incorporate feedback from v18
     - Revert UDS SO_PEERSEC implementation to use lsmblobs
       directly, rather than allocating as needed. The correct
       treatment of out-of-memory conditions in the later case
       is difficult to define. (patch 0005)
     - Use a size_t in append_ctx() (patch 0021)
     - Fix a memory leak when creating compound contexts. (patch 0021)
     Fix build error when CONFIG_SECURITY isn't set (patch 0013)
     Fix build error when CONFIG_SECURITY isn't set (patch 0020)
     Fix build error when CONFIG_SECURITY isn't set (patch 0021)
v18: Rebase to 5.8-rc3
     Incorporate feedback from v17
     - Null pointer checking in UDS (patch 0005)
     Match changes in IMA code (patch 0012)
     Fix the behavior of LSM context supplimental audit
     records so that there's always exactly one when it's
     appropriate for there to be one. This is a substantial
     change that requires extention of the audit_context beyond
     syscall events. (patch 0020)
v17: Rebase to 5.7-rc4
v16: Rebase to 5.6
     Incorporate feedback from v15 - Thanks Stephen, Mimi and Paul
     - Generally improve commit messages WRT scaffolding
     - Comment ima_lsm_isset() (patch 0002)
     - Some question may remain on IMA warning (patch 0002)
     - Mark lsm_slot as __lsm_ro_after_init not __init_data (patch 0002)
     - Change name of lsmblob variable in ima_match_rules() (patch 0003)
     - Instead of putting a struct lsmblob into the unix_skb_parms
       structure put a pointer to an allocated instance. There is
       currently only space for 5 u32's in unix_skb_parms and it is
       likely to get even tighter. Fortunately, the lifecycle
       management of the allocated lsmblob is simple. (patch 0005)
     - Dropped Acks due to the above change (patch 0005)
     - Improved commentary on secmark labeling scaffolding. (patch 0006)
     - Reduced secmark related labeling scaffolding. (patch 0006)
     - Replace use of the zeroth entry of an lsmblob in scaffolding
       with a function lsmblob_value() to hopefully make it less
       obscure. (patch 0006)
     - Convert security_secmark_relabel_packet to use lsmblob as
       this reduces much of the most contentious scaffolding. (patch 0006)
     - Dropped Acks due to the above change (patch 0006)
     - Added BUILD_BUG_ON() for CIPSO tag 6. (patch 0018)
     - Reworked audit subject information. Instead of adding fields in
       the middle of existing records add a new record to the event. When
       a separate record is required use subj="?". (patch 0020)
     - Dropped Acks due to the above change (patch 0020)
     - Reworked audit object information. Instead of adding fields in
       the middle of existing records add a new record to the event. When
       a separate record is required use obj="?". (patch 0021)
     - Dropped Acks due to the above change (patch 0021)
     - Enhanced documentation (patch 0022)
     - Removed unnecessary error code check in security_getprocattr()
       (patch 0021)

     - Revise IMA data use (patch 0002)
     Incorporate feedback from v14
     - Fix lockdown module registration naming (patch 0002)
     - Revise how /proc/self/attr/context is gathered. (patch 0022)
     - Revise access modes on /proc/self/attr/context. (patch 0022)
     - Revise documentation on LSM external interfaces. (patch 0022)
v14: Rebase to 5.5-rc5
     Incorporate feedback from v13
     - Use an array of audit rules (patch 0002)
     - Significant change, removed Acks (patch 0002)
     - Remove unneeded include (patch 0013)
     - Use context.len correctly (patch 0015)
     - Reorder code to be more sensible (patch 0016)
     - Drop SO_PEERCONTEXT as it's not needed yet (patch 0023)
v13: Rebase to 5.5-rc2
     Incorporate feedback from v12
     - Print lsmblob size with %z (Patch 0002)
     - Convert lockdown LSM initialization. (Patch 0002)
     - Restore error check in nft_secmark_compute_secid (Patch 0006)
     - Correct blob scaffolding in ima_must_appraise() (Patch 0009)
     - Make security_setprocattr() clearer (Patch 0013)
     - Use lsm_task_display more widely (Patch 0013)
     - Use passed size in lsmcontext_init() (Patch 0014)
     - Don't add a smack_release_secctx() hook (Patch 0014)
     - Don't print warning in security_release_secctx() (Patch 0014)
     - Don't duplicate the label in nfs4_label_init_security() (Patch 0016)

     - Retain LSMBLOB_FIRST. What was I thinking? (Patch 0023)
     - Add compound context to LSM documentation (Patch 0023)
v12: Rebase to 5.5-rc1
     Fixed a couple of incorrect contractions in the text.
v11: Rebase to 5.4-rc6
     Incorporate feedback from v10
     - Disambiguate reading /proc/.../attr/display by restricting
       all use of the interface to the current process.
     - Fix a merge error in AppArmor's display attribute check
v10: Ask the security modules if the display can be changed.
v9: There is no version 9
v8: Incorporate feedback from v7
    - Minor clean-up in display value management
    - refactor "compound" context creation to use a common
      append_ctx() function.
v7: Incorporate feedback from v6
    - Make setting the display a privileged operation. The
      availability of compound contexts reduces the need for
      setting the display.
v6: Incorporate feedback from v5
    - Add subj_<lsm>= and obj_<lsm>= fields to audit records
    - Add /proc/.../attr/context to get the full context in
      lsmname\0value\0... format as suggested by Simon McVittie
    - Add SO_PEERCONTEXT for getsockopt() to get the full context
      in the same format, also suggested by Simon McVittie.
    - Add /sys/kernel/security/lsm_display_default to provide
      the display default value.
v5: Incorporate feedback from v4
    - Initialize the lsmcontext in security_secid_to_secctx()
    - Clear the lsmcontext in all security_release_secctx() cases
    - Don't use the "display" on strictly internal context
      interfaces.
    - The SELinux binder hooks check for cases where the context
      "display" isn't compatible with SELinux.
v4: Incorporate feedback from v3
    - Mark new lsm_<blob>_alloc functions static
    - Replace the lsm and slot fields of the security_hook_list
      with a pointer to a LSM allocated lsm_id structure. The
      LSM identifies if it needs a slot explicitly. Use the
      lsm_id rather than make security_add_hooks return the
      slot value.
    - Validate slot values used in security.c
    - Reworked the "display" process attribute handling so that
      it works right and doesn't use goofy list processing.
    - fix display value check in dentry_init_security
    - Replace audit_log of secids with '?' instead of deleting
      the audit log
v3: Incorporate feedback from v2
    - Make lsmblob parameter and variable names more
      meaningful, changing "le" and "l" to "blob".
    - Improve consistency of constant naming.
    - Do more sanity checking during LSM initialization.
    - Be a bit clearer about what is temporary scaffolding.
    - Rather than clutter security_getpeersec_dgram with
      otherwise unnecessary checks remove the apparmor
      stub, which does nothing useful.

Patch 01 changes the LSM registration interface to pass a
structure lsm_id containing the name of the module instead of
just the LSM name itself.

Patch 02 introduces uapi/linux/lsm.h and numeric LSM identifiers. 
The numeric ID is added to the lsm_id structure.

Patch 03 Adds the information about which process attributes are
supported by each LSM to the lsm_id structure.

Patch 04 introduces a table of LSM attribute data.

Patch 05 changes security_[gs]etprocattr() to use the LSM ID rather
than the LSM name.

Patch 06 implements the lsm_self_attr() system call.

Patch 07 separates the audit rule processing from the
integrity rule processing. They were never really the
same, but void pointers could hide that. The changes
following use the rule pointers differently in audit
and IMA, so keeping the code common is not a good idea.

Patch 08 moves management of the sock security blob
from the individual modules to the infrastructure.

Patches 09-10 introduce a structure "lsmblob" that will gradually
replace the "secid" as a shorthand for security module information.
At this point lsmblob contains an array of u32 secids, one "slot"
for each of the security modules compiled into the kernel that
used secids. A "slot" is allocated when a security module requests
one.

Patch 11 provides mechanism for the IMA subsystem to identify
explicitly which LSM is subject to IMA policy. This includes
a boot option for specifying the default and an additional option
in IMA rules "lsm=".

Patches 12-19 change LSM interfaces to use the lsmblob instead
of secids. It is important that the lsmblob be a fixed size entity
that does not have to be allocated. Several of the places
where it is used would have performance and/or locking
issues with dynamic allocation.

Patch 20 provides a mechanism for a process to identify which
security module's hooks should be used when displaying or
converting a security context string.  A new prctl() options
PR_LSM_ATTR_[GS]ET get and set which security module to show.
Setting the value requires that all modules using the /proc
interfaces allow the transition. The interface LSM of other
processess can be neither read nor written.

Patch 21 Starts the process of changing how a security
context is represented. Since it is possible for a
security context to have been generated by more than one
security module it is now necessary to note which module
created a security context so that the correct "release"
hook can be called. There are several places where the
module that created a security context cannot be inferred.

This is achieved by introducing a "lsmcontext" structure
which contains the context string, its length and the
"slot" number of the security module that created it.
The security_release_secctx() interface is changed,
replacing the (string,len) pointer pair with a lsmcontext
pointer.

Patches 22-25 convert the security interfaces from
(string,len) pointer pairs to a lsmcontext pointer.
The slot number identifying the creating module is
added by the infrastructure. Where the security context
is stored for extended periods the data type is changed.

Patch 26 converts the Netlabel code to save lsmblob structures
instead of secids. This is not strictly necessary as there can
only be one security module that uses Netlabel at this point.
Using a lsmblob is much cleaner, as the interfaces that use the
data have all been converted.

Patch 27 adds checks to the binder hooks which verify
that both ends of a transaction use the same interface LSM.

Patch 28 adds a parameter to security_secid_to_secctx()
that indicates which of the security modules should be used
to provide the context.

Patches 29-33 update the audit system to better handle auxiliary
records. This requires rearranging the timestamp and serial number
handling. The skb pointer used to collect audit data is replaced
by a list of skb pointers.

Patch 34 adds a supplimental audit record for subject
LSM data when there are multiple security modules with such data.
The AUDIT_MAC_TASK_CONTEXTS record is used in conjuction with a
"subj=?" field to identify the subject data. The
AUDIT_MAC_TASK_CONTEXTS record identifies the security module
with the data: subj_selinux=xyz_t subj_apparmor=abc.

An example of the MAC_TASK_CONTEXTS (1420) record is:

    type=UNKNOWN[1420]
    msg=audit(1600880931.832:113)
    subj_apparmor==unconfined
    subj_smack=_

Patch 35 adds a supplimental audit record for object
LSM data when there are multiple security modules with such data.
The AUDIT_MAC_OBJ_CONTEXTS record is used in conjuction The
with a "obj=?" field to identify the object data.
The AUDIT_MAC_OBJ_CONTEXTS record identifies the security module
with the data: obj_selinux="xyz_t obj_apparmor="abc".  While
AUDIT_MAC_TASK_CONTEXTS records will always contain an entry
for each possible security modules, AUDIT_MAC_OBJ_CONTEXTS
records will only contain entries for security modules for
which the object in question has data.

An example of the MAC_OBJ_CONTEXTS (1421) record is:

    type=UNKNOWN[1421]
    msg=audit(1601152467.009:1050):
    obj_selinux=unconfined_u:object_r:user_home_t:s0

Patches 36-37 clean out scaffolding code.

With all interference on the AppArmor hooks removed,
Patch 38 removes the exclusive bit from AppArmor. An unnecessary
stub hook was also removed.

Patch 39 adds a system call lsm_module_list() that provides a set
of integer LSM ID values describing what is active on the system.

The Ubuntu project is using an earlier version of this patchset in
their distribution to enable stacking for containers.

Performance measurements to date have the change within the "noise".
The sockperf and dbench results are on the order of 0.2% to 0.8%
difference, with better performance being as common as worse. The
benchmarks were run with AppArmor and Smack on Ubuntu.

[PATCH v38 01/39] LSM: Identify modules by more than name

[Casey Schaufler]

Create a struct lsm_id to contain identifying information
about Linux Security Modules (LSMs). At inception this contains
a single member, which is the name of the module. Change the
security_add_hooks() interface to use this structure. Change
the individual modules to maintain their own struct lsm_id and
pass it to security_add_hooks().

Please only use one space after ".lsm". This applies for other commits 
as well.

This command will do the trick:

[PATCH v38 02/39] LSM: Add an LSM identifier for external use

[Casey Schaufler]

Add an integer member "id" to the struct lsm_id. This value is
a unique identifier associated with each security module. The
values are defined in a new UAPI header file. Each existing LSM
has been updated to include it's LSMID in the lsm_id.

What do you have in mind? Why not "reserve" higher bits instead and 
start with SELinux at 1?

Please only use one space after ".id"

I don't know what (if anything) Paul had in mind when he suggested the reserved values.
It's not like there's a shortage of numbers, and as it's part of the ABI and can't
change I'll err on the side of caution.

Order of inclusion upstream. Except for capability. In the next version
I plan to fix the order by putting LSM_ID_CAPABILITY first at 32 and
changing the comment. If we wanted something less mundane we could hex
encode the first 4 letters of the name, but except for hacker style debugging
that doesn't gain anything.

Yeah, I got that from the comments on 01/39. I will make that change
throughout the set.

[PATCH v38 03/39] LSM: Identify the process attributes for each module

[Casey Schaufler]

Add an integer member "features" to the struct lsm_id which
identifies the API related data associated with each security
module. The initial set of features maps to information that
has traditionaly been available in /proc/self/attr.

[PATCH v38 04/39] LSM: Maintain a table of LSM attribute data

[Casey Schaufler]

As LSMs are registered add their lsm_id pointers to a table.
This will be used later for attribute reporting.

I'm not happy with LSMID_ENTRIES. This is a way towards forever forbidding LKM-based LSMs.

I'm fine with using UAPI-visible constants for switching /proc/ files.
But TOMOYO does not need such constant because TOMOYO does not use /proc/ files.

Also, lsm_self_attr() will be limited for LSM modules which use /proc/ files, and
therefore I think prctl() will be already there.

I don't see any way given the locking issues that we're ever going to
mix built in security modules and loaded security modules on the same
hook lists. The SELinux module deletion code is sufficiently scary that
it is being removed. That does not mean that I think loadable modules
are impossible, I think it means that their management is going to have
to be separate, the same way the BPF programs are handled. The only way
that I see a unified hook list is for all the LSMs to be implemented as
loadable modules, and I can't see that happening in my lifetime.

I can see an LSM like BPF, as I mentioned before, that manages loaded
modules. Over the years I've seen several designs that might work. I'm
encouraged (and not a little bit frightened) by the success of the BPF
work.

Converting the array[LSMID_ENTRIES] implementation to a hlist like the
hooks have used would not be that big a project and I don't see that
making such a change would be a show-stopper for implementing loadable
modules. I think that a lot of other issues would be more significant.

I will, on the other hand, listen to compelling arguments. It is not the
intention of this code to lock out loadable modules. If I thought it would
I would not have proposed it.

While the proposed set of attributes map to those in /proc/.../attr there is
no reason to assume they will be limited to those. I can see providing several
of the Smack attributes currently manipulated in smackfs, such as relabel-self.
If we are providing SELinux specific values like keycreate there's no reason
we can't provide Smack or TOMOYO specific values as well.

I'm not expecting for unloadable LSM modules.
I'm expecting for loadable LSM modules.

I'm not expecting to make all LSM modules to be implemented as loadable
LSM modules, for some want to associate "security label" to everything
(including processes which might start before the global init process starts)
but others do not need to associate "security label" to everything.

There can be LSM modules whose lifetime of hooks match the lifetime of
a process which registered hooks for that process. In that case, being
automatically unregistered upon process termination would be preferable.

But there are LSM modules whose lifetime of hooks is irrelevant to a process
which registered a hook for that process. In that case, we need a method for
allowing registered hooks to remain even after that process terminated.

Please don't think loadable LSM modules as something that require special
handling. TOMOYO is an LSM module whose lifetime of hooks is irrelevant to
a process which registered a hook for that process, but does not need to
associate "security label" to everything. It has to be trivial to convert
TOMOYO as a loadable LSM module.

Defining constants for each LSM module (i.e. "LSM: Add an LSM identifier
for external use") is the show-stopper for implementing loadable modules.
We won't be able to accept whatever LSM modules to upstream, and we won't
be able to enable whatever LSM modules in distributor kernels.

LSM modules which cannot define a constant due to either "not accepted
to upstream" or "not enabled by distributor kernels" will be forbidden.
I expect that we assign a constant upon module registration (instead of
API visible constants) if we require all LSM modules to have a constant.

This code is exactly for locking out loadable modules.

Imagine a situation where two individuals independently develop their own
web applications using the same identifier, and then their web applications
started working together with other web applications using that identifier.
When they published their web applications for public and wider use, a problem
that both web applications are already using the same identifier arises.
It is too late to reassign the identifier.

The same trouble can happen with loadable LSM modules. Unless the upstream kernel
behaves as if a DNS registerer that assigns a unique domainname for whatever web
sites (regardless of whether a web site is for public or not), defining a permanent
constant for LSM module is a way towards locking out loadable LSM modules. And it
is well possible that a loadable LSM module wants to run on older kernels which
do not have LSM id defined yet.

This "define LSM id as userspace visible constant" is more dangerous than just
reserving some space for future use. You are trying to control all IP addresses
for the sake of only in-tree LSM modules. No, no, no, please don't do that...

It's really no more dangerous than using the LSM name. What if two developers
implement modules and both name it "belllapadula"? User space won't be able to
tell the difference if they base behavior on the module name. That's one thing
that a loadable module mechanism is going to need to address that a built-in
mechanism doesn't.

I don't see that having a built-in version of TOMOYO and a loadable version
needs to be difficult. That's something that whoever creates the loadable
security module scheme is going to have to address. It will depend on the
details of the loadable module mechanism. I can't comment on how that will
work because I don't see loadable modules hitting the top of my queue.

One possible way for loadable modules to work would be to have a built-in
module LSM_ID_MODLOADER which maintains its own list of module hooks.
The values returned from lsm_self_attr() would identify the this LSM
and the data value would have to identify the loaded module it refers to,
perhaps as "TOMOYO=XYZ" or "datastate=foobar". A flag LSM_ATTR_LOADED would
indicate that the attribute needed to be processed according to loadable
module attribute rules, whatever they might be.

So no, it's not a show stopper. Not any more than u32 secids are a showstopper
for process attributes it audit records. LSM IDs are inconvenient, and not my
first choice, but I'm not going to let that get in the way of getting this
code upstream.

A built in module loader security module would address this issue.
Getting such a module accepted upstream is not going to be trivial,
but the BPF people seem to have managed it.

Maybe the thing to do is rewrite TOMOYO in eBPF. If I wanted to have a
loadable security module I could either take ten years or so to get a
loadable module scheme upstream in addition to my module, or I could
write it in eBPF and use it the next day. I don't know enough about eBPF
programming to say if it has everything TOMOYO needs, but it sure looks
like an easier path if it does.

I hope that I have suggested viable (if not convenient) alternatives.
I suppose it is possible that locking out loadable modules is one
motivation behind the LSM ID scheme, but I really doubt it. And more
importantly, as I've outlined above, I can't be successful in locking
out loadable security modules. I don't even see it as an additional
complication.

How can we guarantee that a built-in module loader security module is
always built-in ? What I'm insisting is that "warrant the freedom to load
loadable LSM modules without recompiling the whole kernel".

Sure, we can load LSM modules which were not built into distributor kernels
if we can recompile the whole kernel". But give me a break, that's a stupid
opinion for non-kernel developers. People won't replace distributor kernels
with rebuilt kernels only for enabling LSM modules which were not built into
distributor kernels.

Even if TOMOYO could be rewritten in eBPF (I don't think it is possible), how TOMOYO
can be loaded into distributor kernels if distributions turn the BPF LSM off ?

Not only it will be very hard to get the loadable module manager LSM upstream,
it will be also very hard to keep the loadable module manager LSM enabled in
distributor kernels.

Again, how can we guarantee that a built-in module loader security module is
always built-in ?

What I'm insisting is that "warrant the freedom to load loadable LSM modules
without recompiling the whole kernel".

Adding EXPORT_SYMBOL_GPL(security_hook_heads) is the only way that can "allow
LSM modules which distributors cannot support to be legally loaded".

Any fixed-sized array like lsm_idlist[LSMID_ENTRIES] that defines max capacity
based on whether that LSM module is built-in will lock out loadable LSM modules.
Thus, I'm not happy with LSMID_ENTRIES.

If the upstream kernel assigns an LSM id for all LSM modules including out-of-tree
and/or private LSM modules (that's why I described that the upstream kernel behaves
as if a DNS registerer), we can assign LSM id = 100 to "belllapadula" from A and
LSM id = 101 to "belllapadula" from B, and both "belllapadula" modules can work
without conflicts by using LSM id. Of course, this implies that we need to preserve
unused space in lsm_idlist[LSMID_ENTRIES] etc. for such LSM modules (if we use
fixed-sized array rather than a linked list).

You can't. That's up to the distribution. Just like BPF.

Since security modules are optional and the LSM infrastructure
itself is optional you can't ensure that any given kernel would
support a loadable security module.

Of course the upstream kernel isn't going to have LSM IDs for out-of-tree
security modules. That's one of many reasons loadable modules are going to
have to be treated differently from built-in modules, if they're allowed
at all.

Like I propose adding EXPORT_SYMBOL_GPL(security_hook_heads),
I'm not taking about distributors who choose CONFIG_SECURITY=n.

No. You are just handwaving/postponing the problem using something unknown
that is not yet shown as a workable code. Anything that can be disabled via
kernel config option cannot be an alternative.

The biggest problem is that quite few developers show interest in loadable LSM modules.
How many developers responded to this topic? Once the ability to allow loadable LSM
modules is technically lost, nobody shall be able to revive it. You will be happy with
ignoring poor people.

You are already and completely trapped into "only in-tree and supported by distributors
is correct" crap.

Then, I have to hate your idea of having fixed sized array.

[PATCH v38 05/39] proc: Use lsmids instead of lsm names for attrs

[Casey Schaufler]

Use the LSM ID number instead of the LSM name to identify which
security module's attibute data should be shown in /proc/self/attr.
The security_[gs]etprocattr() functions have been changed to expect
the LSM ID. The change from a string comparison to an integer comparison
in these functions will provide a minor performance improvement.

[PATCH v38 06/39] LSM: lsm_self_attr syscall for LSM self attributes

[Casey Schaufler]

Create a system call lsm_self_attr() to provide the security
module maintained attributes of the current process. Historically
these attributes have been exposed to user space via entries in
procfs under /proc/self/attr.

Attributes are provided as a collection of lsm_ctx structures
which are placed into a user supplied buffer. Each structure
identifys the security module providing the attribute, which
of the possible attributes is provided, the size of the
attribute, and finally the attribute value. The format of the
attribute value is defined by the security module, but will
always be \0 terminated. The ctx_len value will be larger than
strlen(ctx).

Re: [PATCH v38 06/39] LSM: lsm_self_attr syscall for LSM self attributes

[Mickaël Salaün]

At least linux-api@vger.kernel.org should be in Cc for new syscalls.

You need a dedicated patch to wire this syscall with all architectures. 
It will help a lot dealing with merge conflicts because of other new 
syscalls. You can take a look at the Landlock syscall implementations: 
https://git.kernel.org/c/torvalds/a49f4f81cb48925e8d7cbd9e59068f516e984144

About the name, I'd suggest using a verb, something like lsm_get_self_attr.

I think this paragraph is not enough to justify a new syscall. We should 
highlight what is not possible (or difficult) to do with the filesystem: 
e.g.
- usable in a sandbox which may not have access to the filesystem (but 
is that a good thing here?);
- clearly defined ABI/format;
- …?

What is the goal of this syscall? How will it be used? By who?

To avoid holes in this struct, you might want to use

I'd prefer @size to not be a pointer but a value, and then only be read 
to get the context size.

lsm_module_list() already returns the enabled LSM IDs. It would be much 
simpler to only returns the properties of a specified LSM.
The syscall could then look like this:
lsm_get_self_attr(__u32 lsm_id, char *attr, size_t size, __u32 flags)

Hi Casey,

I had hoped to get to review these patches earlier this week, I know
you are very anxious to see something happen here, but unfortunately
that didn't work out and I'm now in a position of limited network
access and time for a bit.  I will do my best to at least comment on
the new syscall related additions, but thankfully you've already
started to get some good comments from others so I'm hopeful that will
help you keep moving forward.

One comment I did want to make, and it's important: please separate
the LSM syscall patches from the LSM stacking patches.  While the
stacking patches will obviously be dependent on the syscall patches,
the syscall patches should not be dependent on stacking.  However, the
LSM syscall patches must be designed from the start to support
multiple, simultaneous LSMs.

Thanks.

Thanks. I just got back to work myself. Hopefully the comments will prove
useful. I'm just getting to them.

OK. I will refactor into two patch sets. The first will be the syscalls
for getting the LSM attributes and the second will be the stacking changes.
The prctl() I proposed to set the "display" LSM will be in the second, as
it makes no sense to have without anything to change. I have not to date
included the SO_PEERCONTEXT that would be required for complete stacking.
Would you like to see that included in the syscall patches?

Thank you.

[PATCH v38 07/39] integrity: disassociate ima_filter_rule from security_audit_rule

[Casey Schaufler]

Create real functions for the ima_filter_rule interfaces.
These replace #defines that obscure the reuse of audit
interfaces. The new functions are put in security.c because
they use security module registered hooks that we don't
want exported.

[PATCH v38 08/39] LSM: Infrastructure management of the sock security

[Casey Schaufler]

Move management of the sock->sk_security blob out
of the individual security modules and into the security
infrastructure. Instead of allocating the blobs from within
the modules the modules tell the infrastructure how much
space is required, and the space is allocated there.

[PATCH v38 09/39] LSM: Add the lsmblob data structure.

[Casey Schaufler]

When more than one security module is exporting data to
audit and networking sub-systems a single 32 bit integer
is no longer sufficient to represent the data. Add a
structure to be used instead.

The lsmblob structure is currently an array of
u32 "secids". There is an entry for each of the security
modules built into the system that would use secids if
active. The system assigns the module a "slot" when it
registers hooks. If modules are compiled in but not
registered there will be unused slots. The slot number
is added to the lsm_id structure.

The audit rules data is expanded to use an array of
security module data rather than a single instance.
A new structure audit_lsm_rules is defined to avoid the
confusion which commonly accompanies the use of
void ** parameters.

[PATCH v38 11/39] IMA: avoid label collisions with stacked LSMs

[Casey Schaufler]

Integrity measurement may filter on security module information
and needs to be clear in the case of multiple active security
modules which applies. Provide a boot option ima_rules_lsm= to
allow the user to specify an active security module to apply
filters to. If not specified, use the first registered module
that supports the audit_rule_match() LSM hook. Allow the user
to specify in the IMA policy an lsm= option to specify the
security module to use for a particular rule.

[PATCH v38 12/39] LSM: Use lsmblob in security_audit_rule_match

[Casey Schaufler]

Change the secid parameter of security_audit_rule_match
to a lsmblob structure pointer. Pass the entry from the
lsmblob structure for the approprite slot to the LSM hook.

Change the users of security_audit_rule_match to use the
lsmblob instead of a u32. The scaffolding function lsmblob_init()
fills the blob with the value of the old secid, ensuring that
it is available to the appropriate module hook. The sources of
the secid, security_task_getsecid() and security_inode_getsecid(),
will be converted to use the blob structure later in the series.
At the point the use of lsmblob_init() is dropped.

[PATCH v38 13/39] LSM: Use lsmblob in security_kernel_act_as

[Casey Schaufler]

Change the security_kernel_act_as interface to use a lsmblob
structure in place of the single u32 secid in support of
module stacking. Change its only caller, set_security_override,
to do the same. Change that one's only caller,
set_security_override_from_ctx, to call it with the new
parameter type.

The security module hook is unchanged, still taking a secid.
The infrastructure passes the correct entry from the lsmblob.
lsmblob_init() is used to fill the lsmblob structure, however
this will be removed later in the series when security_secctx_to_secid()
is updated to provide a lsmblob instead of a secid.

[PATCH v38 15/39] LSM: Use lsmblob in security_secid_to_secctx

[Casey Schaufler]

Change security_secid_to_secctx() to take a lsmblob as input
instead of a u32 secid. It will then call the LSM hooks
using the lsmblob element allocated for that module. The
callers have been updated as well. This allows for the
possibility that more than one module may be called upon
to translate a secid to a string, as can occur in the
audit code.

[PATCH v38 16/39] LSM: Use lsmblob in security_ipc_getsecid

[Casey Schaufler]

There may be more than one LSM that provides IPC data
for auditing. Change security_ipc_getsecid() to fill in
a lsmblob structure instead of the u32 secid. The
audit data structure containing the secid will be updated
later, so there is a bit of scaffolding here.

[PATCH v38 17/39] LSM: Use lsmblob in security_current_getsecid

[Casey Schaufler]

Change the security_current_getsecid_subj() and
security_task_getsecid_obj() interfaces to fill in
a lsmblob structure instead of a u32 secid in support of
LSM stacking. Audit interfaces will need to collect all
possible secids for possible reporting.

[PATCH v38 18/39] LSM: Use lsmblob in security_inode_getsecid

[Casey Schaufler]

Change the security_inode_getsecid() interface to fill in a
lsmblob structure instead of a u32 secid. This allows for its
callers to gather data from all registered LSMs. Data is provided
for IMA and audit.

[PATCH v38 19/39] LSM: Use lsmblob in security_cred_getsecid

[Casey Schaufler]

Change the security_cred_getsecid() interface to fill in a
lsmblob instead of a u32 secid. The associated data elements
in the audit sub-system are changed from a secid to a lsmblob
to accommodate multiple possible LSM audit users.

[PATCH v38 20/39] LSM: Specify which LSM to display

[Casey Schaufler]

Create two new prctl() options PR_LSM_ATTR_SET and PR_LSM_ATTR_GET
which change and report the Interface LSM respectively.

The LSM ID number of an active LSM that supplies hooks for
human readable data may be passed in the arg2 value with the
PR_LSM_ATTR_SET option. The PR_LSM_ATT_GET option returns the
LSM ID currently in use. At this point there can only be one LSM
capable of display active. A helper function lsm_task_ilsm() is
provided to get the interface lsm slot for a task_struct.

Security modules that wish to restrict this action may provide
a task_prctl hook to do so. Each such security module is
responsible for defining its policy.

AppArmor hook initially provided by John Johansen
<john.johansen@canonical.com>. SELinux hook initially provided by
Stephen Smalley <stephen.smalley.work@gmail.com>

[PATCH v38 21/39] LSM: Ensure the correct LSM context releaser

[Casey Schaufler]

Add a new lsmcontext data structure to hold all the information
about a "security context", including the string, its size and
which LSM allocated the string. The allocation information is
necessary because LSMs have different policies regarding the
lifecycle of these strings. SELinux allocates and destroys
them on each use, whereas Smack provides a pointer to an entry
in a list that never goes away.

[PATCH v38 22/39] LSM: Use lsmcontext in security_secid_to_secctx

[Casey Schaufler]

Replace the (secctx,seclen) pointer pair with a single
lsmcontext pointer to allow return of the LSM identifier
along with the context and context length. This allows
security_release_secctx() to know how to release the
context. Callers have been modified to use or save the
returned data from the new structure.

security_secid_to_secctx() will now return the length value
if the passed lsmcontext pointer is NULL.

[PATCH v38 23/39] LSM: Use lsmcontext in security_inode_getsecctx

[Casey Schaufler]

Change the security_inode_getsecctx() interface to fill
a lsmcontext structure instead of data and length pointers.
This provides the information about which LSM created the
context so that security_release_secctx() can use the
correct hook.

[PATCH v38 24/39] Use lsmcontext in security_dentry_init_security

[Casey Schaufler]

Replace the (secctx,seclen) pointer pair with a single
lsmcontext pointer to allow return of the LSM identifier
along with the context and context length. This allows
security_release_secctx() to know how to release the
context. Callers have been modified to use or save the
returned data from the new structure.

Special care is taken in the NFS code, which uses the
same data structure for its own copied labels as it does
for the data which comes from security_dentry_init_security().
In the case of copied labels the data has to be freed, not
released.

[PATCH v38 26/39] NET: Store LSM netlabel data in a lsmblob

[Casey Schaufler]

Netlabel uses LSM interfaces requiring an lsmblob and
the internal storage is used to pass information between
these interfaces, so change the internal data from a secid
to a lsmblob. Update the netlabel interfaces and their
callers to accommodate the change. This requires that the
modules using netlabel use the lsm_id.slot to access the
correct secid when using netlabel.

[PATCH v38 27/39] binder: Pass LSM identifier for confirmation

[Casey Schaufler]

Send an identifier for the security module interface_lsm
along with the security context. This allows the receiver
to verify that the receiver and the sender agree on which
security module's context is being used. If they don't
agree the message is rejected.

than or equal to zero, the security module associated with
that LSM "slot" is used. If the value is LSMBLOB_DISPLAY
the "interface lsm" is used. If the value is LSMBLOB_FIRST
the first security module providing a hook is used.

The integrity IMA subsystem has chosen to always use the
LSMBLOB_FIRST behavior, regardless of the lsm_display values.

[PATCH v38 29/39] Audit: Keep multiple LSM data in audit_names

[Casey Schaufler]

Replace the osid field in the audit_names structure
with a lsmblob structure. This accommodates the use
of an lsmblob in security_audit_rule_match() and
security_inode_getsecid().

[PATCH v38 32/39] Audit: Allow multiple records in an audit_buffer

[Casey Schaufler]

Replace the single skb pointer in an audit_buffer with
a list of skb pointers. Add the audit_stamp information
to the audit_buffer as there's no guarantee that there
will be an audit_context containing the stamp associated
with the event. At audit_log_end() time create auxiliary
records (none are currently defined) as have been added
to the list. Functions are created to manage the skb list
in the audit_buffer.

[PATCH v38 33/39] Audit: Add record for multiple task security contexts

[Casey Schaufler]

Create a new audit record AUDIT_MAC_TASK_CONTEXTS.
An example of the MAC_TASK_CONTEXTS (1420) record is:

    type=MAC_TASK_CONTEXTS[1420]
    msg=audit(1600880931.832:113)
    subj_apparmor=unconfined
    subj_smack=_

When an audit event includes a AUDIT_MAC_TASK_CONTEXTS record
the "subj=" field in other records in the event will be "subj=?".
An AUDIT_MAC_TASK_CONTEXTS record is supplied when the system has
multiple security modules that may make access decisions based
on a subject security context.

[PATCH v38 35/39] Audit: Add record for multiple object contexts

[Casey Schaufler]

Create a new audit record AUDIT_MAC_OBJ_CONTEXTS.
An example of the MAC_OBJ_CONTEXTS (1421) record is:

    type=MAC_OBJ_CONTEXTS[1421]
    msg=audit(1601152467.009:1050):
    obj_selinux=unconfined_u:object_r:user_home_t:s0

When an audit event includes a AUDIT_MAC_OBJ_CONTEXTS record
the "obj=" field in other records in the event will be "obj=?".
An AUDIT_MAC_OBJ_CONTEXTS record is supplied when the system has
multiple security modules that may make access decisions based
on an object security context.

[PATCH v38 38/39] AppArmor: Remove the exclusive flag

[Casey Schaufler]

With the inclusion of the interface LSM process attribute
mechanism AppArmor no longer needs to be treated as an
"exclusive" security module. Remove the flag that indicates
it is exclusive. Remove the stub getpeersec_dgram AppArmor
hook as it has no effect in the single LSM case and
interferes in the multiple LSM case.

With lsm_self_attr(), this would look like a dir/file structure.

Would it be useful for user space to list all the currently used LSMs 
instead of only retrieving information about a known (list of) LSM?
What is the use case for this syscall?

As for the other syscall, this should also be in the same dedicated 
"wire syscalls" patch.

I'm not sure I understand what you mean by this. I think you're suggesting
that lsm_module_list() shows the list of possibilities and lsm_self_attr()
shows the data. That's roughly correct. Note that many security modules
will never provide any data in lsm_self_attr(), and that others will
only provide it when it has been explicitly set.

I believe so. User space tends to lag behind kernel features. ps(1) can report
the "current" value for any LSM without knowing which module supplied the value
today by using the /proc/self/attr/current interface. id(1) could do the same
were it not unnecessarily coded to be SELinux specific. lsm_module_list(2), like
the existing /sys/kernel/security/lsm interface, allows an application to know
if it should address the modules it knows about. It also provides the LSM order,
which could be significant to systemd, dbus, auditd or other sophisticated system
services.


> What is the use case for this syscall?

1. Identify if a specific LSM is in the list.
	Used by ps(1) to format the -Z output correctly
	Used by systemd(1) to determine which service start options to support
	Used by dbus to identify what policy to enforce at runtime
2. Identify the order of LSMs in the list.
	Will AppArmor data show up in /proc/self/attr/current, or will Smack data?

Please test that flags == 0 so it can be used in the future:

No need to repeat this, if it is written first.

No need for the alloc/free. Here's what I would imagine for the whole
thing:

	if (flags)
		return -EINVAL;

	if (get_user(usize, size))
		return -EFAULT;

	if (put_user(total_size, size) != 0)
		return -EFAULT;

	if (usize < total_size)
		return -E2BIG;

	for (i = 0; i < lsm_id; i++)
		if (put_user(lsm_idlist[i]->id, id++))
			return -EFAULT;

	return lsm_id;
