apparmor: Remove deadcode

2024-11-27T03:21:05Z

aa_label_audit, aa_label_find, aa_label_seq_print and aa_update_label_name were added by commit f1bd904175e8 ("apparmor: add the base fns() for domain labels") but never used. aa_profile_label_perm was added by commit 637f688dc3dc ("apparmor: switch from profiles to using labels on contexts") but never used. aa_secid_update was added by commit c092921219d2 ("apparmor: add support for mapping secids and using secctxes") but never used. aa_split_fqname has been unused since commit 3664268f19ea ("apparmor: add namespace lookup fns()") aa_lookup_profile has been unused since commit 93c98a484c49 ("apparmor: move exec domain mediation to using labels") aa_audit_perms_cb was only used by aa_profile_label_perm (see above). All of these commits are from around 2017. Remove them. Signed-off-by: Dr. David Alan Gilbert Signed-off-by: John Johansen

apparmor: refcount the pdb

2023-10-18T22:30:47Z

With the move to permission tables the dfa is no longer a stand alone entity when used, needing a minimum of a permission table. However it still could be shared among different pdbs each using a different permission table. Instead of duping the permission table when sharing a pdb, add a refcount to the pdb so it can be easily shared. Reviewed-by: Georgia Garcia Signed-off-by: John Johansen

apparmor: Free up __cleanup() name

2023-06-26T09:14:18Z

In order to use __cleanup for __attribute__((__cleanup__(func))) the name must not be used for anything else. Avoid the conflict. Signed-off-by: Peter Zijlstra (Intel) Acked-by: John Johansen Link: https://lkml.kernel.org/r/20230612093537.536441207%40infradead.org

apparmor: extend permissions to support a label and tag string

2022-10-03T21:49:03Z

add indexes for label and tag entries. Rename the domain table to the str_table as its a shared string table with label and tags. Signed-off-by: John Johansen

apparmor: preparse for state being more than just an integer

2022-10-03T21:49:03Z

Convert from an unsigned int to a state_t for state position. This is a step in prepping for the state position carrying some additional flags, and a limited form of backtracking to support variables. Signed-off-by: John Johansen

apparmor: fix absroot causing audited secids to begin with =

2022-07-09T22:13:58Z

AppArmor is prefixing secids that are converted to secctx with the = to indicate the secctx should only be parsed from an absolute root POV. This allows catching errors where secctx are reparsed back into internal labels. Unfortunately because audit is using secid to secctx conversion this means that subject and object labels can result in a very unfortunate == that can break audit parsing. eg. the subj==unconfined term in the below audit message type=USER_LOGIN msg=audit(1639443365.233:160): pid=1633 uid=0 auid=1000 ses=3 subj==unconfined msg='op=login id=1000 exe="/usr/sbin/sshd" hostname=192.168.122.1 addr=192.168.122.1 terminal=/dev/pts/1 res=success' Fix this by switch the prepending of = to a _. This still works as a special character to flag this case without breaking audit. Also move this check behind debug as it should not be needed during normal operqation.

apparmor: fix zero-length compiler warning in AA_BUG()

2021-11-03T08:08:15Z

Uses of AA_BUG() without a message can result in the compiler warning warning: zero-length gnu_printf format string [-Wformat-zero-length] Fix this with a pragma for now. A larger rework of AA_BUG() will follow. Signed-off-by: John Johansen

apparmor: avoid -Wempty-body warning

2021-11-03T07:46:12Z

Building with 'make W=1' shows a warning for an empty macro: security/apparmor/label.c: In function '__label_update': security/apparmor/label.c:2096:59: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body] 2096 | AA_BUG(labels_ns(label) != labels_ns(new)); Change the macro definition to use no_printk(), which improves format string checking and avoids the warning.
