git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull overflow updates from Kees Cook: "The end goal of the current buffer overflow detection work[0] is to gain full compile-time and run-time coverage of all detectable buffer overflows seen via array indexing or memcpy(), memmove(), and memset(). The str*() family of functions already have full coverage. While much of the work for these changes have been on-going for many releases (i.e. 0-element and 1-element array replacements, as well as avoiding false positives and fixing discovered overflows[1]), this series contains the foundational elements of several related buffer overflow detection improvements by providing new common helpers and FORTIFY_SOURCE changes needed to gain the introspection required for compiler visibility into array sizes. Also included are a handful of already Acked instances using the helpers (or related clean-ups), with many more waiting at the ready to be taken via subsystem-specific trees[2]. The new helpers are: - struct_group() for gaining struct member range introspection - memset_after() and memset_startat() for clearing to the end of structures - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs Also included is the beginning of the refactoring of FORTIFY_SOURCE to support memcpy() introspection, fix missing and regressed coverage under GCC, and to prepare to fix the currently broken Clang support. Finishing this work is part of the larger series[0], but depends on all the false positives and buffer overflow bug fixes to have landed already and those that depend on this series to land. As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time and run-time tests are added for FORTIFY_SOURCE and the mem*()-family functions respectively. The compile time tests have found a legitimate (though corner-case) bug[6] already. Please note that the appearance of "panic" and "BUG" in the FORTIFY_SOURCE refactoring are the result of relocating existing code, and no new use of those code-paths are expected nor desired. Finally, there are two tree-wide conversions for 0-element arrays and flexible array unions to gain sane compiler introspection coverage that result in no known object code differences. After this series (and the changes that have now landed via netdev and usb), we are very close to finally being able to build with -Warray-bounds and -Wzero-length-bounds. However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build. Hopefully these can be solved soon" Link: https://lore.kernel.org/lkml/20210818060533.3569517-1-keescook@chromium.org/ [0] Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?qt=grep&q=FORTIFY_SOURCE [1] Link: https://lore.kernel.org/lkml/202108220107.3E26FE6C9C@keescook/ [2] Link: https://lore.kernel.org/lkml/3ab153ec-2798-da4c-f7b1-81b0ac8b0c5b@roeck-us.net/ [3] Link: https://bugs.llvm.org/show_bug.cgi?id=51682 [4] Link: https://lore.kernel.org/lkml/202109051257.29B29745C0@keescook/ [5] Link: https://lore.kernel.org/lkml/20211020200039.170424-1-keescook@chromium.org/ [6] * tag 'overflow-v5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (30 commits) fortify: strlen: Avoid shadowing previous locals compiler-gcc.h: Define __SANITIZE_ADDRESS__ under hwaddress sanitizer treewide: Replace 0-element memcpy() destinations with flexible arrays treewide: Replace open-coded flex arrays in unions stddef: Introduce DECLARE_FLEX_ARRAY() helper btrfs: Use memset_startat() to clear end of struct string.h: Introduce memset_startat() for wiping trailing members and padding xfrm: Use memset_after() to clear padding string.h: Introduce memset_after() for wiping trailing members/padding lib: Introduce CONFIG_MEMCPY_KUNIT_TEST fortify: Add compile-time FORTIFY_SOURCE tests fortify: Allow strlen() and strnlen() to pass compile-time known lengths fortify: Prepare to improve strnlen() and strlen() warnings fortify: Fix dropped strcpy() compile-time write overflow check fortify: Explicitly disable Clang support fortify: Move remaining fortify helpers into fortify-string.h lib/string: Move helper functions out of string.c compiler_types.h: Remove __compiletime_object_size() cm4000_cs: Use struct_group() to zero struct cm4000_dev region can: flexcan: Use struct_group() to zero struct flexcan_regs regions ...

The variable err is not necessary in such places. It should be revmoved for the simplicity of the code. This will cause the double parentheses to be redundant, and the inner parentheses should be deleted. The clang_analyzer complains as follows: net/xfrm/xfrm_input.c:533: warning: net/xfrm/xfrm_input.c:563: warning: Although the value stored to 'err' is used in the enclosing expression, the value is never actually read from 'err'.

2021-10-18xfrm: Use memset_after() to clear paddingKees Cook2-4/+2
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Clear trailing padding bytes using the new helper so that memset() doesn't get confused about writing "past the end" of the last struct member. There is no change to the resulting machine code.

Syzbot hit shift-out-of-bounds in xfrm_get_default.

2021-07-21net/xfrm/compat: Copy xfrm_spdattr_type_t atributesDmitry Safonov1-5/+44
The attribute-translator has to take in mind maxtype, that is xfrm_link::nla_max. When it is set, attributes are not of xfrm_attr_type_t. Currently, they can be only XFRMA_SPD_MAX (message XFRM_MSG_NEWSPDINFO), their UABI is the same for 64/32-bit, so just copy them. Thanks to YueHaibing for reporting this: In xfrm_user_rcv_msg_compat() if maxtype is not zero and less than XFRMA_MAX, nlmsg_parse_deprecated() do not initialize attrs array fully. xfrm_xlate32() will access uninit 'attrs[i]' while iterating all attrs array.

As the default we assume the traffic to pass, if we have no matching IPsec policy. With this patch, we have a possibility to change this default from allow to block. It can be configured via netlink. Each direction (input/output/forward) can be configured separately. With the default to block configuered, we need allow policies for all packet flows we accept.

2021-07-02xfrm: Fix RCU vs hash_resize_mutex lock inversionFrederic Weisbecker1-9/+8
xfrm_bydst_resize() calls synchronize_rcu() while holding hash_resize_mutex. But then on PREEMPT_RT configurations, xfrm_policy_lookup_bytype() may acquire that mutex while running in an RCU read side critical section. This results in a deadlock. In fact the scope of hash_resize_mutex is way beyond the purpose of xfrm_policy_lookup_bytype() to just fetch a coherent and stable policy for a given destination/direction, along with other details. The lower level net->xfrm.xfrm_policy_lock, which among other things protects per destination/direction references to policy entries, is enough to serialize and benefit from priority inheritance against the write side. As a bonus, it makes it officially a per network namespace synchronization business where a policy table resize on namespace A shouldn't block a policy lookup on namespace B.

2021-06-22xfrm: Fix xfrm offload fallback fail caseAyush Sawal1-0/+1
In case of xfrm offload, if xdo_dev_state_add() of driver returns -EOPNOTSUPP, xfrm offload fallback is failed. In xfrm state_add() both xso->dev and xso->real_dev are initialized to dev and when err(-EOPNOTSUPP) is returned only xso->dev is set to null. So in this scenario the condition in func validate_xmit_xfrm(), if ((x->xso.dev != dev) && (x->xso.real_dev == dev)) return skb; returns true, due to which skb is returned without calling esp_xmit() below which has fallback code. Hence the CRYPTO_FALLBACK is failing. So fixing this with by keeping x->xso.real_dev as NULL when err is returned in func xfrm_dev_state_add().

In commit 68dc022d04eb ("xfrm: BEET mode doesn't support fragments for inner packets"), it tried to fix the issue that in TX side the packet is fragmented before the ESP encapping while in the RX side the fragments always get reassembled before decapping with ESP. This is not true for IPv6. IPv6 is different, and it's using exthdr to save fragment info, as well as the ESP info. Exthdrs are added in TX and processed in RX both in order. So in the above case, the ESP decapping will be done earlier than the fragment reassembling in TX side. Here just remove the fragment check for the IPv6 inner packets to recover the fragments support for BEET mode.

2021-06-01xfrm: policy: Read seqcount outside of rcu-read side in ↵Varad Gautam1-7/+14
xfrm_policy_lookup_bytype xfrm_policy_lookup_bytype loops on seqcount mutex xfrm_policy_hash_generation within an RCU read side critical section. Although ill advised, this is fine if the loop is bounded. xfrm_policy_hash_generation wraps mutex hash_resize_mutex, which is used to serialize writers (xfrm_hash_resize, xfrm_hash_rebuild). This is fine too. On PREEMPT_RT=y, the read_seqcount_begin call within xfrm_policy_lookup_bytype emits a mutex lock/unlock for hash_resize_mutex. Mutex locking is fine, since RCU read side critical sections are allowed to sleep with PREEMPT_RT. xfrm_hash_resize can, however, block on synchronize_rcu while holding hash_resize_mutex. This leads to the following situation on PREEMPT_RT, where the writer is blocked on RCU grace period expiry, while the reader is blocked on a lock held by the writer: Thead 1 (xfrm_hash_resize) Thread 2 (xfrm_policy_lookup_bytype) rcu_read_lock(); mutex_lock(&hash_resize_mutex); read_seqcount_begin(&xfrm_policy_hash_generation); mutex_lock(&hash_resize_mutex); // block xfrm_bydst_resize(); synchronize_rcu(); // block <RCU stalls in xfrm_policy_lookup_bytype> Move the read_seqcount_begin call outside of the RCU read side critical section, and do an rcu_read_unlock/retry if we got stale data within the critical section. On non-PREEMPT_RT, this shortens the time spent within RCU read side critical section in case the seqcount needs a retry, and avoids unbounded looping.

While testing ipcomp on a realtime kernel, Xiumei reported a "sleeping in atomic" bug, caused by a memory allocation while preemption is disabled (ipcomp_decompress -> alloc_page -> ... get_page_from_freelist). As Sebastian noted [1], this get_cpu() isn't actually needed, since ipcomp_decompress() is called in napi context anyway, so BH is already disabled. This patch replaces get_cpu + per_cpu_ptr with this_cpu_ptr, then simplifies the error returns, since there isn't any common operation left.

2021-04-19xfrm: xfrm_state_mtu should return at least 1280 for ipv6Sabrina Dubroca1-2/+12
Jianwen reported that IPv6 Interoperability tests are failing in an IPsec case where one of the links between the IPsec peers has an MTU of 1280. The peer generates a packet larger than this MTU, the router replies with a "Packet too big" message indicating an MTU of 1280. When the peer tries to send another large packet, xfrm_state_mtu returns 1280 - ipsec_overhead, which causes ip6_setup_cork to fail with EINVAL. We can fix this by forcing xfrm_state_mtu to return IPV6_MIN_MTU when IPv6 is used. After going through IPsec, the packet will then be fragmented to obey the actual network's PMTU, just before leaving the host. Currently, TFC padding is capped to PMTU - overhead to avoid fragementation: after padding and encapsulation, we still fit within the PMTU. That behavior is preserved in this patch.
