net/sched: clear actions pointer in miss cookie init fail

2023-04-17T09:06:23+00:00

Palash reports a UAF when using a modified version of syzkaller[1].

When 'tcf_exts_miss_cookie_base_alloc()' fails in 'tcf_exts_init_ex()'
a call to 'tcf_exts_destroy()' is made to free up the tcf_exts
resources.
In flower, a call to '__fl_put()' when 'tcf_exts_init_ex()' fails is made;
Then calling 'tcf_exts_destroy()', which triggers an UAF since the
already freed tcf_exts action pointer is lingering in the struct.

Before the offending patch, this was not an issue since there was no
case where the tcf_exts action pointer could linger. Therefore, restore
the old semantic by clearing the action pointer in case of a failure to
initialize the miss_cookie.

net: sched: sch_qfq: prevent slab-out-of-bounds in qfq_activate_agg

2023-04-14T09:59:26+00:00

If the TCA_QFQ_LMAX value is not offered through nlattr, lmax is determined by the MTU value of the network device.
The MTU of the loopback device can be set up to 2^31-1.
As a result, it is possible to have an lmax value that exceeds QFQ_MIN_LMAX.

Due to the invalid lmax value, an index is generated that exceeds the QFQ_MAX_INDEX(=24) value, causing out-of-bounds read/write errors.

The following reports a oob access:

net/sched: act_api: add specific EXT_WARN_MSG for tc action

2023-03-17T04:25:45+00:00

In my previous commit 0349b8779cc9 ("sched: add new attr TCA_EXT_WARN_MSG
to report tc extact message") I didn't notice the tc action use different
enum with filter. So we can't use TCA_EXT_WARN_MSG directly for tc action.
Let's add a TCA_ROOT_EXT_WARN_MSG for tc action specifically and put this
param before going to the TCA_ACT_TAB nest.

This reverts commit 923b2e30dc9cd05931da0f64e2e23d040865c035.

This is not a correct fix as TCA_EXT_WARN_MSG is not a hierarchy to
TCA_ACT_TAB. I didn't notice the TC actions use different enum when adding
TCA_EXT_WARN_MSG. To fix the difference I will add a new WARN enum in
TCA_ROOT_MAX as Jamal suggested.

net/sched: flower: fix fl_change() error recovery path

2023-03-01T08:49:54+00:00

The two "goto errout;" paths in fl_change() became wrong
after cited commit.

Indeed we only must not call __fl_put() until the net pointer
has been set in tcf_exts_init_ex()

This is a minimal fix. We might in the future validate TCA_FLOWER_FLAGS
before we allocate @fnew.

net/sched: act_sample: fix action bind logic

2023-02-26T18:27:45+00:00

The TC architecture allows filters and actions to be created independently.
In filters the user can reference action objects using:
tc action add action sample ... index 1
tc filter add ... action pedit index 1

In the current code for act_sample this is broken as it checks netlink
attributes for create/update before actually checking if we are binding to an
existing action.

net/sched: act_pedit: fix action bind logic

2023-02-26T18:27:45+00:00

The TC architecture allows filters and actions to be created independently.
In filters the user can reference action objects using:
tc action add action pedit ... index 1
tc filter add ... action pedit index 1

In the current code for act_pedit this is broken as it checks netlink
attributes for create/update before actually checking if we are binding to an
existing action.

tdc results:
