  • dd8dbf2e6   security: report the module name to security_module_request ... Browse Code »

    For SELinux to do better filtering in userspace we send the name of the
    module along with the AVC denial when a program is denied module_request.

    Example output:

    type=SYSCALL msg=audit(11/03/2009 10:59:43.510:9) : arch=x86_64 syscall=write success=yes exit=2 a0=3 a1=7fc28c0d56c0 a2=2 a3=7fffca0d7440 items=0 ppid=1727 pid=1729 auid=unset uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=(none) ses=unset comm=rpc.nfsd exe=/usr/sbin/rpc.nfsd subj=system_u:system_r:nfsd_t:s0 key=(null)
    type=AVC msg=audit(11/03/2009 10:59:43.510:9) : avc: denied { module_request } for pid=1729 comm=rpc.nfsd kmod="net-pf-10" scontext=system_u:system_r:nfsd_t:s0 tcontext=system_u:system_r:kernel_t:s0 tclass=system

  • c720c7e83   inet: rename some inet_sock fields ... Browse Code »

    In order to have better cache layouts of struct sock (separate zones
    for rx/tx paths), we need this preliminary patch.

    Goal is to transfert fields used at lookup time in the first
    read-mostly cache line (inside struct sock_common) and move sk_refcnt
    to a separate cache line (only written by rx path)

    This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,
    sport and id fields. This allows a future patch to define these
    fields as macros, like sk_refcnt, without name clashes.

  • d81165919   lsm: Use a compressed IPv6 string format in audit events ... Browse Code »

    Currently the audit subsystem prints uncompressed IPv6 addresses which not
    only differs from common usage but also results in ridiculously large audit
    strings which is not a good thing. This patch fixes this by simply converting
    audit to always print compressed IPv6 addresses.

    Old message example:

    audit(1253576792.161:30): avc: denied { ingress } for
    saddr=0000:0000:0000:0000:0000:0000:0000:0001 src=5000
    daddr=0000:0000:0000:0000:0000:0000:0000:0001 dest=35502 netif=lo
    scontext=system_u:object_r:unlabeled_t:s15:c0.c1023
    tcontext=system_u:object_r:lo_netif_t:s0-s15:c0.c1023 tclass=netif

    New message example:

    audit(1253576792.161:30): avc: denied { ingress } for
    saddr=::1 src=5000 daddr=::1 dest=35502 netif=lo
    scontext=system_u:object_r:unlabeled_t:s15:c0.c1023
    tcontext=system_u:object_r:lo_netif_t:s0-s15:c0.c1023 tclass=netif

  • 2bf496903   SELinux: Convert avc_audit to use lsm_audit.h ... Browse Code »

    Convert avc_audit in security/selinux/avc.c to use lsm_audit.h,
    for better maintainability.

    - changed selinux to use common_audit_data instead of
    avc_audit_data
    - eliminated code in avc.c and used code from lsm_audit.h instead.

    Had to add a LSM_AUDIT_NO_AUDIT to lsm_audit.h so that avc_audit
    can call common_lsm_audit and do the pre and post callbacks without
    doing the actual dump. This makes it so that the patched version
    behaves the same way as the unpatched version.

    Also added a denied field to the selinux_audit_data private space,
    once again to make it so that the patched version behaves like the
    unpatched.

    I've tested and confirmed that AVCs look the same before and after
    this patch.

  • 6e837fb15   smack: implement logging V3 ... Browse Code »

    This patch creates auditing functions usable by LSM to audit security
    events. It provides standard dumping of FS, NET, task etc ... events
    (code borrowed from SELinux)
    and provides 2 callbacks to define LSM specific auditing, which should be
    flexible enough to convert SELinux too.
