Logically, EFX_BUG_ON_PARANOID can never be correct. For, BUG_ON should only be used if it is not possible to continue without potential harm; and since the non-DEBUG driver will continue regardless (as the BUG_ON is compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver. So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID or the newly defined EFX_WARN_ON_ONCE_PARANOID. Signed-off-by: NEdward Cree <ecree@solarflare.com> Signed-off-by: NDavid S.

Sargun Dhillon says: ==================== samples, bpf: Refactor; Add automated tests for cgroups These two patches are around refactoring out some old, reusable code from the existing test_current_task_under_cgroup_user test, and adding a new, automated test. There is some generic cgroupsv2 setup & cleanup code, given that most environment still don't have it setup by default. With this code, we're able to pretty easily add an automated test for future cgroupsv2 functionality. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds the sample program test_cgrp2_attach2. This program is similar to test_cgrp2_attach, but it performs automated testing of the cgroupv2 BPF attached filters. It runs the following checks: * Simple filter attachment * Application of filters to child cgroups * Overriding filters on child cgroups * Checking that this still works when the parent filter is removed The filters that are used here are simply allow all / deny all filters, so it isn't checking the actual functionality of the filters, but rather the behaviour around detachment / attachment. If net_cls is enabled, this test will fail. Signed-off-by: NSargun Dhillon <sargun@sargun.me> Acked-by: NAlexei Starovoitov <ast@kernel.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

net_generic() function is both a) inline and b) used ~600 times. It has the following code inside ... ptr = ng->ptr[id - 1]; ... "id" is never compile time constant so compiler is forced to subtract 1. And those decrements or LEA [r32 - 1] instructions add up. We also start id'ing from 1 to catch bugs where pernet sybsystem id is not initialized and 0. This is quite pointless idea (nothing will work or immediate interference with first registered subsystem) in general but it hints what needs to be done for code size reduction. Namely, overlaying allocation of pointer array and fixed part of structure in the beginning and using usual base-0 addressing. Ids are just cookies, their exact values do not matter, so lets start with 3 on x86_64.

Publishing net_generic pointer is done with silly mistake: new array is published BEFORE setting freshly acquired pernet subsystem pointer. memcpy rcu_assign_pointer kfree_rcu ng->ptr[id - 1] = data; This bug was introduced with commit dec827d1 ("[NETNS]: The generic per-net pointers.") in the glorious days of chopping networking stack into containers proper 8.5 years ago (whee...) How it didn't trigger for so long? Well, you need quite specific set of conditions: *) race window opens once per pernet subsystem addition (read: modprobe or boot) *) not every pernet subsystem is eligible (need ->id and ->size) *) not every pernet subsystem is vulnerable (need incorrect or absense of ordering of register_pernet_sybsys() and actually using net_generic()) *) to hide the bug even more, default is to preallocate 13 pointers which is actually quite a lot. You need IPv6, netfilter, bridging etc together loaded to trigger reallocation in the first place. Trimmed down config are OK.

nla_ok() consists of 3 clauses: 1) int rem >= (int)sizeof(struct nlattr) 2) u16 nla_len >= sizeof(struct nlattr) 3) u16 nla_len <= int rem The statement is that clause (1) is redundant. What it does is ensuring that "rem" is a positive number, so that in clause (3) positive number will be compared to positive number with no problems. However, "u16" fully fits into "int" and integers do not change value when upcasting even to signed type. Negative integers will be rejected by clause (3) just fine. Small positive integers will be rejected by transitivity of comparison operator. NOTE: all of the above DOES NOT apply to nlmsg_ok() where ->nlmsg_len is u32(!), so 3 clauses AND A CAST TO INT are necessary.

Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Qian Zhang (张谦) reported a potential socket buffer overflow in tipc_msg_build() which is also known as CVE-2016-8632: due to insufficient checks, a buffer overflow can occur if MTU is too short for even tipc headers. As anyone can set device MTU in a user/net namespace, this issue can be abused by a regular user. As agreed in the discussion on Ben Hutchings' original patch, we should check the MTU at the moment a bearer is attached rather than for each processed packet. We also need to repeat the check when bearer MTU is adjusted to new device MTU. UDP case also needs a check to avoid overflow when calculating bearer MTU.
