2013-01-11linux/audit.h: move ptrace.h include to kernel headerMike Frysinger
While the kernel internals want pt_regs (and so it includes linux/ptrace.h), the user version of audit.h does not need it. So move the include out of the uapi version. This avoids issues where people want the audit defines and userland ptrace api. Including both the kernel ptrace and the userland ptrace headers can easily lead to failure.

2013-01-11audit: create explicit AUDIT_SECCOMP event typeKees Cook
The seccomp path was using AUDIT_ANOM_ABEND from when seccomp mode 1 could only kill a process. While we still want to make sure an audit record is forced on a kill, this should use a separate record type since seccomp mode 2 introduces other behaviors. In the case of "handled" behaviors (process wasn't killed), only emit a record if the process is under inspection. This change also fixes userspace examination of seccomp audit events, since it was considered malformed due to missing fields of the AUDIT_ANOM_ABEND event type.

2012-10-12audit: allow audit code to satisfy getname requests from its names_listJeff Layton
Currently, if we call getname() on a userland string more than once, we'll get multiple copies of the string and multiple audit_names records.

2012-10-12vfs: define struct filename and have getname() return itJeff Layton
getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-10-12audit: overhaul __audit_inode_child to accomodate retryingJeff Layton
In order to accomodate retrying path-based syscalls, we need to add a new "type" argument to audit_inode_child. This will tell us whether we're looking for a child entry that represents a create or a delete. If we find a parent, don't automatically assume that we need to create a new entry. Instead, use the information we have to try to find an existing entry first. Update it if one is found and create a new one if not.

2012-10-12audit: set the name_len in audit_inode for parent lookupsJeff Layton
Currently, this gets set mostly by happenstance when we call into audit_inode_child. While that might be a little more efficient, it seems wrong. If the syscall ends up failing before audit_inode_child ever gets called, then you'll have an audit_names record that shows the full path but has the parent inode info attached. Fix this by passing in a parent flag when we call audit_inode that gets set to the value of LOOKUP_PARENT. We can then fix up the pathname for the audit entry correctly from the get-go. While we're at it, clean up the no-op macro for audit_inode in the !CONFIG_AUDITSYSCALL case. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

When using audit on OpenRISC, an audit arch is needed.

2012-09-17audit: Add typespecific uid and gid comparatorsEric W. Biederman
The audit filter code guarantees that uid are always compared with uids and gids are always compared with gids, as the comparason operations are type specific. Take advantage of this proper to define audit_uid_comparator and audit_gid_comparator which use the type safe comparasons from uidgid.h. Build on audit_uid_comparator and audit_gid_comparator and replace audit_compare_id with audit_compare_uid and audit_compare_gid. This is one of those odd cases where being type safe and duplicating code leads to simpler shorter and more concise code. Don't allow bitmask operations in uid and gid comparisons in audit_data_to_entry. Bitmask operations are already denined in audit_rule_to_entry. Convert constants in audit_rule_to_entry and audit_data_to_entry into kuids and kgids when appropriate. Convert the uid and gid field in struct audit_names to be of type kuid_t and kgid_t respectively, so that the new uid and gid comparators can be applied in a type safe manner.

2012-01-17audit: inline audit_syscall_entry to reduce burden on archsEric Paris

2012-01-17Audit: push audit success and retcode into arch ptrace.hEric Paris
The audit system previously expected arches calling to audit_syscall_exit to supply as arguments if the syscall was a success and what the return code was. Audit also provides a helper AUDITSC_RESULT which was supposed to simplify things by converting from negative retcodes to an audit internal magic value stating success or failure. This helper was wrong and could indicate that a valid pointer returned to userspace was a failed syscall. The fix is to fix the layering foolishness. We now pass audit_syscall_exit a struct pt_reg and it in turns calls back into arch code to collect the return value and to determine if the syscall was a success or failure. We also define a generic is_syscall_success() macro which determines success/failure based on if the value is < -MAX_ERRNO. This works for arches like x86 which do not use a separate mechanism to indicate syscall failure. We make both the is_syscall_success() and regs_return_value() static inlines instead of macros. The reason is because the audit function must take a void* for the regs. (uml calls theirs struct uml_pt_regs instead of just struct pt_regs so audit_syscall_exit can't take a struct pt_regs). Since the audit function takes a void* we need to use static inlines to cast it back to the arch correct structure to dereference it. The other major change is that on some arches, like ia64, MIPS and ppc, we change regs_return_value() to give us the negative value on syscall failure. THE only other user of this macro, kretprobe_example.c, won't notice and it makes the value signed consistently for the audit functions across all archs. In arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old audit code as the return value. But the ptrace_64.h code defined the macro regs_return_value() as regs[3]. I have no idea which one is correct, but this patch now uses the regs_return_value() function, so it now uses regs[3]. For powerpc we previously used regs->result but now use the regs_return_value() function which uses regs->gprs[3]. regs->gprs[3] is always positive so the regs_return_value(), much like ia64 makes it negative before calling the audit code when appropriate.

2011-06-30netfilter: add SELinux context support to AUDIT targetMr Dash Four
In this revision the conversion of secid to SELinux context and adding it to the audit log is moved from xt_AUDIT.c to audit.c with the aid of a separate helper function - audit_log_secctx - which does both the conversion and logging of SELinux context, thus also preventing internal secid number being leaked to userspace. If conversion is not successful an error is raised. With the introduction of this helper function the work done in xt_AUDIT.c is much more simplified. It also opens the possibility of this helper function being used by other modules (including auditd itself), if desired. With this addition, typical (raw auditd) output after applying the patch would be: type=NETFILTER_PKT msg=audit(1305852240.082:31012): action=0 hook=1 len=52 inif=? outif=eth0 saddr=10.1.1.7 daddr=10.1.2.1 ipid=16312 proto=6 sport=56150 dport=22 obj=system_u:object_r:ssh_client_packet_t:s0 type=NETFILTER_PKT msg=audit(1306772064.079:56): action=0 hook=3 len=48 inif=eth0 outif=? smac=00:05:5d:7c:27:0b dmac=00:02:b3:0a:7f:81 macproto=0x0800 saddr=10.1.2.1 daddr=10.1.1.7 ipid=462 proto=6 sport=22 dport=3561 obj=system_u:object_r:ssh_server_packet_t:s0 Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: Mr Dash Four <mr.dash.four@googlemail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
